Luminescence of Sm3+ in double perovskite-type Ba2SrWO6 for insect trapping.

The predominant method for pest control has been the use of pesticides, which have been shown to have detrimental effects on soil, freshwater, and crop quality. Therefore, the development of novel and sustainable crop protection strategies has become increasingly imperative. In this study, a novel orange-red emitting Ba2SrWO6: Sm3+ phosphor was synthesized using the high-temperature solid-state reaction. Under ultraviolet excitation, the phosphors showed obvious emission peaks at 575, 614, and 662 nm. The Ba2SrWO6: Sm3+ was used to fabricate a fluorescence film with polydimethylsiloxane (PDMS), and attracted twice as many insects as the blank control group under 365 nm ultraviolet light. This material holds great potential as a fluorescent agent for insect trapping in the pest control fields of tea, cotton, eggplant, rice, potato, grape, and other agricultural industries. Our findings provide an eco-friendly approach to pest management for the increment of food production.

MoS2 Hollow Multishelled Nanospheres Doped Fe Single Atoms Capable of Fast Phase Transformation for Fast-charging Na-ion Batteries.

Low Na+ and electron diffusion kinetics severely restrain the rate capability of MoS2 as anode for sodium-ion batteries (SIBs). Slow phase transitions between 2H and 1T, and from NaxMoS2 to Mo and Na2S as well as the volume change during cycling, induce a poor cycling stability. Herein, an original Fe single atom doped MoS2 hollow multishelled structure (HoMS) is designed for the first time to address the above challenges. The Fe single atom in MoS2 promotes the electron transfer, companying with shortened charge diffusion path from unique HoMS, thereby achieving excellent rate capability. The strong adsorption with Na+ and self-catalysis of Fe single atom facilitates the reversible conversion between 2H and 1T, and from NaxMoS2 to Mo and Na2S. Moreover, the buffering effect of HoMS on volume change during cycling improves the cyclic stability. Consequently, the Fe single atom doped MoS2 quadruple-shelled sphere exhibits a high specific capacity of 213.3 mAh g-1 at an ultrahigh current density of 30 A g-1, which is superior to previously-reported results. Even at 5 A g-1, 259.4 mAh g-1 (83.68 %) was reserved after 500 cycles. Such elaborate catalytic site decorated HoMS is also promising to realize other "fast-charging" high-energy-density rechargeable batteries.

A New Type of Si-Based MOSFET for Radiation Reinforcement.

This paper thoroughly analyses the role of drift in the sensitive region in the single-event effect (SEE), with the aim of enhancing the single-particle radiation resistance of N-type metal-oxide semiconductor field-effect transistors (MOSFETs). It proposes a design for a Si-based device structure that extends the lightly doped source-drain region of the N-channel metal-oxide semiconductor (NMOS), thereby moderating the electric field of the sensitive region. This design leads to a 15.69% decrease in the charge collected at the leaky end of the device under the standard irradiation conditions. On this basis, a device structure is further proposed to form a composite metal-oxide semiconductor (MOS) by connecting a pn junction at the lightly doped source-drain end. By adding two charge paths, the leakage collection charge is further reduced by 13.85% under standard irradiation conditions. Moreover, the deterioration of the drive current in the purely growing lightly doped source-drain region can be further improved. Simulations of single-event effects under different irradiation conditions show that the device has good resistance to single-event irradiation, and the composite MOS structure smoothly converges to a 14.65% reduction in drain collection charge between 0.2 pC/µm and 1 pC/µm Linear Energy Transfer (LET) values. The incidence position at the source-to-channel interface collects the highest charge reduction rate of 28.23%. The collecting charge reduction rate is maximum, at 17.12%, when the incidence is at a 45-degree angle towards the source.

Neutron penumbral image reconstruction with a convolution neural network using fast Fourier transform.

In Inertial Confinement Fusion (ICF), the asymmetry of a hot spot is an important influence factor in implosion performance. Neutron penumbral imaging, which serves as an encoded-aperture imaging technique, is one of the most important diagnostic methods for detecting the shape of a hot spot. The detector image is a uniformly bright range surrounded by a penumbral area, which presents the strength distribution of hot spots. The present diagnostic modality employs an indirect imaging technique, necessitating the reconstruction process to be a pivotal aspect of the imaging protocol. The accuracy of imaging and the applicable range are significantly influenced by the reconstruction algorithm employed. We develop a neural network named Fast Fourier transform Neural Network (FFTNN) to reconstruct two-dimensional neutron emission images from the penumbral area of the detector images. The FFTNN architecture consists of 16 layers that include a FFT layer, convolution layer, fully connected layer, dropout layer, and reshape layer. Due to the limitations in experimental data, we propose a phenomenological method for describing hot spots to generate datasets for training neural networks. The reconstruction performance of the trained FFTNN is better than that of the traditional Wiener filtering and Lucy-Richardson algorithm on the simulated dataset, especially when the noise level is high as indicated by the evaluation metrics, such as mean squared error and structure similar index measure. This proposed neural network provides a new perspective, paving the way for integrating neutron imaging diagnosis into ICF.

Novel Ge-Based Plasma TFET with High Rectification Efficiency for 2.45 GHz Microwave Wireless Weak Energy Transmission.

The enhancement of rectification efficiency in 2.45 GHz microwave wireless weak energy transmission systems is centred on rectifier device selection. The overall rectification efficiency of traditional rectifier devices is low in weak energy density situations, failing to fulfil the commercial requirements of this region. The subthreshold swing of the emerging device TFET exceeds 60 mV/dec, which has the advantages of a large open-state current and a small off-state current in the corresponding region of the weak energy density. In view of this, this paper designs a double-gate plasma rectifier TFET with an embedded n+ heavily doped layer on the basis of a PNPN-structured TFET, where the device is simulated with the MixedMode module of Silvaco TCAD 2018, the rectification efficiency at -10 dBm is 44.12%, which is 10.61% higher than that of the PNPN-TFET, and the efficiency in the weak energy density region is generally 10% or more than that of commercial HSMS devices, showing obvious rectification advantages.

Surface Crystal Modification of Na3 V2 (PO4 )3 to Cast Intermediate Na2 V2 (PO4 )3 Phase toward High-Rate Sodium Storage.

The two-phase reaction of Na3 V2 (PO4 )3 - Na1 V2 (PO4 )3 in Na3 V2 (PO4 )3 (NVP) is hindered by low electronic and ionic conductivity. To address this problem, a surface-N-doped NVP encapsulating by N-doped carbon nanocage (N-NVP/N-CN) is rationally constructed, wherein the nitrogen is doped in both the surface crystal structure of NVP and carbon layer. The surface crystal modification decreases the energy barrier of Na+ diffusion from bulk to electrolyte, enhances intrinsic electronic conductivity, and releases lattice stress. Meanwhile, the porous architecture provides more active sites for redox reactions and shortens the diffusion path of ion. Furthermore, the new interphase of Na2 V2 (PO4 )3 is detected by in situ XRD and clarified by density functional theory (DFT) calculation with a lower energy barrier during the fast reversible electrochemical three-phase reaction of Na3 V2 (PO4 )3 - Na2 V2 (PO4 )3 - Na1 V2 (PO4 )3 . Therefore, as cathode of sodium-ion battery, the N-NVP/N-CN exhibited specific capacities of 119.7 and 75.3 mAh g-1 at 1 C and even 200 C. Amazingly, high capacities of 89.0, 86.2, and 84.6 mAh g-1 are achieved after overlong 10000 cycles at 20, 40, and 50 C, respectively. This approach provides a new idea for surface crystal modification to cast intermediate Na2 V2 (PO4 )3 phase for achieving excellent cycling stability and rate capability.

CircRNA PGAM1 Promotes the Migration and Invasion of Pancreatic Adenocarcinoma Cells by Activating the AKT/mTOR Signaling Pathway.

Pancreatic adenocarcinoma (PAAD) is a lethal malignancy of the gastrointestinal tract. Circular RNA, an endogenous noncoding RNA, is considered a new regulatory molecule in tumorigenesis and development. Here, we aimed to investigate the role of circPGAM1 in PAAD. The PAAD cell line HPAC was transfected with OE-circPGAM1 to overexpress circPGAM1 and treated with AZD5363 to inhibit the AKT/mTOR pathway. Simultaneously, another PAAD cell line BxPC-3 was transfected with sh-circPGAM1 to silence circPGAM1. The GEPIA database was used to determine the expression of circPGAM1 in PAAD and its association with overall and disease-free survival. CircPGAM1 expression levels were determined in cell lines using reverse transcription-quantitative PCR. The cell counting kit-8, wound healing, and transwell assays were performed to determine cell migration and invasion. The protein expression levels of phosphorylated AKT and mTOR were determined using western blotting. CircPGAM1 was overexpressed in PAAD and related to poor prognosis. Silencing circPGAM1 inhibited migration and invasion of BxPC-3 cells, and overexpression of circPGAM1 showed the opposite effects. Overall, circPGAM1 promoted the migration and invasion of PAAD cells through the AKT/mTOR axis.

PI3K/AKT/mTOR pathway and its related molecules participate in PROK1 silence-induced anti-tumor effects on pancreatic cancer.

The PI3K/AKT/mTOR (phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin) pathway can be initiated by PROK1 (prokineticin 1), but its effect and mechanism of action in pancreatic carcinoma (PC) are not fully understood. In this study, we elucidated the roles of PROK1 and its related molecules in PC in vivo. PANC-1 cells with PROK1 knockdown were injected into BALB/c nude mice. The growth and weight of the tumor were monitored and measured, which was followed by TUNEL (terminal deoxynucleotidyl transferase biotin-dUTP nick end labeling), immunohistochemical staining, and hematoxylin and eosin staining. The key proteins related to proliferation, apoptosis, and the PI3K/AKT/mTOR pathway were determined by Western blotting. We also used public databases to identify the molecules related to PROK1. The reduction of PROK1 inhibited angiopoiesis and promoted apoptosis in vivo. PCNA-1, cyclin D1, and Bcl-2 decreased considerably, while Bax and cleaved caspase-3 increased significantly after PROK1 inhibition. The PI3K/AKT/mTOR signal inhibition was also closely associated with PROK1 knockdown. The possible related molecules of PROK1, such as von Willebrand factor, were screened and considered to be involved in the aberrant activation of PI3K/AKT. In conclusion, PROK1 knockdown significantly prevented tumor growth and promoted apoptosis of human PC cells in vivo, where the PI3K/AKT/mTOR pathway was probably inhibited. Therefore, PROK1, along with its related molecules, might be important targets for PC therapy.

Oxidation of tetracycline hydrochloride with a photoenhanced MIL-101(Fe)/g-C3N4/PMS system: Synergetic effects and radical/nonradical pathways.

MIL-101(Fe)-based catalysts have been widely used for degradation of organic pollutants based on peroxymonosulfate (PMS) activation. Hence, a facile calcination and hydrothermal method was used in this study to prepare a MIL-101(Fe)/g-C3N4 composite catalyst with high activity and high stability for PMS activation to degrade tetracycline hydrochloride (TC) under visible-light irradiation. We clearly elucidated the mechanism involved in the MIL-101(Fe)/g-C3N4 photo Fenton-catalyzed PMS activation process by separating the PMS activation and pollutant oxidation processes. The synergetic effects of MIL-101(Fe) and g-C3N4 involved MIL-101(Fe) acting as an electron shuttle mediating electron transfer from the organic substrate to PMS, accompanied by redox cycling of the surface Fe(II)/Fe(III). Multiple experimental results indicated that PMS was bound to the surface of MIL-101(Fe)/g-C3N4 during visible irradiation and generation of sulfate radicals (SO4•-), hydroxyl radicals (•OH) and superoxide anion free radicals (•O2-) for the radical pathway and singlet oxygen (1O2) and holes (h+) for the nonradical pathway. The major degradation pathways for TC can be described as demethylation, deamination, deamidation and carbonylation. This work provides valuable information and advances the fundamental understanding needed for design and syntheses of metal-free conjugated polymers modified by metal-organic frameworks for heterogeneous photo-Fenton reactions.

Cobalt and nitrogen co-doped monolithic carbon foam for ultrafast degradation of emerging organic pollutants via peroxymonosulfate activation.

Cobalt-based catalysts are expected as one of the most promising peroxymonosulfate (PMS) activators for the removal of organic pollutants from industrial wastewater. However, the easy agglomeration, difficult separation, and secondary pollution of cobalt ions limit their practical application. In this study, a novel, highly efficient, reusable cobalt and nitrogen co-doped monolithic carbon foam (Co-N-CMF) was utilized to activate PMS for ultrafast pollutant degradation. Co-N-CMF (0.2 g/L) showed ultrafast catalytic kinetics and higher total organic carbon (TOC) removal efficiency. Bisphenol A, ciprofloxacin, 2,4-dichlorophenoxyacetic acid, and 2,4-dichlorophenol could be completely degraded after 2, 4, 5, and 5 min, and the TOC removal efficiencies were 77.4 %, 68.9 %, 72.8 %, and 79.8 %, respectively, corresponding to the above pollution. The sulfate radical (SO4•-) was the main reactive oxygen species in Co-N-CMF/PMS based on electron paramagnetic resonance. The ecological structure-activity relationship program analysis via the quantitative structure activity relationship analysis and phytotoxicity assessment revealed that the Co-N-CMF/PMS system demonstrates good ecological safety and ecological compatibility. The Co-N-CMF catalyst has good catalytic activity and facile recycling, which provides a fine method with excellent PMS activation capacity for 2,4-dichlorophenol elimination from simulated industrial wastewater. This study provides new insights into the development of monolithic catalysts for ultrafast wastewater treatment via PMS activation.

Analysis of Serum Levels of IFN-γ, IL-4, and TNF-α in Patients with Cervicitis Complicated by HPV Infection and Their Clinical Significance.

In order to investigate the expression levels of serum IFN-γ, IL-4, and tumor necrosis TNF-α in patients with cervicitis complicated with human papillomavirus (HPV) infection and clinical significance, a retrospective study was conducted on 90 patients with chronic cervicitis complicated by HP V infection who visited our hospital from June 2020 to June 2021, and they are included in the research group. According to the degree of HPV infection, the patients are divided into low-risk HPV type group (n = 65 cases) and high-risk HPV type group (n = 25 cases); 50 patients with cervicitis (without HPV infection) who received treatment in our hospital are selected as control group 1. Fifty healthy women who underwent physical examination are selected as the control group 2. The general data of the two groups of patients during hospitalization are collected, and HPV-DNA, IFN-γ, IL-4, and TNF-α are detected in all patients. For patients with cervicitis complicated by HPV infection, the IFN-indexes in the body are significantly decreased, IL-4 and TNF-αare significantly increased, and with the degree of HPV infection, IFN-γ, IL-4, and TNF-α have high diagnostic performance with HPV infection, and there is a significant correlation between the three, which can be used in cervicitis complicated with HPV infection. It is widely used in the early diagnosis and screening of infected patients.

Interlayer-Expanded MoS2 Nanoflowers Vertically Aligned on MXene@Dual-Phased TiO2 as High-Performance Anode for Sodium-Ion Batteries.

As a promising energy-storage and conversion anode material for high-power sodium-ion batteries operated at room temperature, the practical application of layered molybdenum disulfide (MoS2) is hindered by volumetric expansion during cycling. To address this issue, a rational design of MoS2 with enlarged lattice spacing aligned vertically on hierarchically porous Ti3C2Tx MXene nanosheets with partially oxidized rutile and anatase dual-phased TiO2 (MoS2@MXene@D-TiO2) composites via one-step hydrothermal method without following anneal process is reported. This unique "plane-to-surface" structure accomplishes hindering MoS2 from aggregating and restacking, enabling sufficient electrode/electrolyte interaction simultaneously. Meanwhile, the heterogeneous structure among dual-phased TiO2, MoS2, and MXene could constitute a built-in electric field, promoting high Na+ transportation. As a result, the as-constructed 3D MoS2@MXene@D-TiO2 heterostructure delivers admirable high-rate reversible capacity (359.6 mAh g-1 up to 5 A g-1) at room temperature, excellent cycling stability (about 200 mAh g-1) at a low temperature of -30 °C, and superior electrochemical performance in Na+ full batteries by coupling with a Na3V2(PO4)3 cathode. This ingenious design is clean and facile to inspire the potential of advanced low-dimensional heterogeneous structure electrode materials in the application of high-performance sodium-ion batteries.

Interfacial charge-transfer enhances the dual-function of the porous NiCo2S4@SiO2 heterojunction for high-performance Li-S batteries.

Porous NiCo2S4@SiO2 is employed as the sulfur host. The negatively charged SiO2 can increase the charge density and conductivity of NiCo2S4 and accelerate the conversion of sulfur. The charge transfer effect would in turn reduce the electrostatic repulsion between SiO2 and negatively charged polysulfide, thereby enhancing the adsorption of polysulfides.

Application of CoMn/CoFe layered double hydroxide based on metal-organic frameworks template to activate peroxymonosulfate for 2,4-dichlorophenol degradation.

Metal-organic frameworks (MOFs) have unique properties and stable structures, which have been widely used as templates/precursors to prepare well developed pore structure and high specific surface area materials. In this article, an innovative and facile method of crystal reorganization was designed by using MOFs as sacrificial templates to prepare a layered double hydroxide (LDH) nano-layer sheet structure through a pseudomorphic conversion process under alkaline conditions. The obtained CoMn-LDH and CoFe-LDH catalysts broke the ligand of MOFs and reorganized the structure on the basis of retaining a high specific surface area and a large number of pores, which had higher specific surface area and well developed pore structure compared with LDH catalysts prepared by traditional methods, and thus provide more active sites to activate peroxymonosulfate (PMS). Due to the unique framework structure of MOFs, the MOF-derived CoMn-LDH and CoFe-LDH catalysts could provide more active sites to activate PMS, and achieve a 2,4-dichlorophenol degradation of 99.3% and 99.2% within 20 minutes, respectively. In addition the two LDH catalysts displayed excellent degradation performance for bisphenol A, ciprofloxacin and 2,4-dichlorophenoxyacetic acid (2,4-D). X-ray photoelectron spectroscopy indicated that the valence state transformation of metal elements participated in PMS activation. Electron paramagnetic resonance manifested that sulfate radical (SO4•-) and singlet oxygen (1O2) were the main species for degrading pollutants. In addition, after the three-cycle experiment, the CoMn-LDH and CoFe-LDH catalysts also showed long-term stability with a slight activity decrease in the third cycle. The phytotoxicity assessment determined by the germination of mung beans proved that PMS activation by MOF-derived LDH catalysts can basically eliminate the phytotoxicity of a 2,4-D solution. This research not only developed high-activity LDH catalysts for PMS activation, but also expanded the environmental applications of MOF derivants.

Treatment of acute pancreatitis with early pancreatic stenting: a case series of 336 patients.

BACKGROUND: Pancreatic duct (PD) obstruction and hypertension may play a central role in the onset and progression of acute pancreatitis (AP). However, only a few studies have reported using pancreatic stenting to relieve PD obstruction in the early phase of AP, with conflicting results. Whether pancreatic stenting is effective in the early phase of AP remains unknown. We conducted this experiment in order to study the therapeutic efficacy and safety of pancreatic stenting in the early stage of AP. METHODS: We conducted a retrospective analysis of 336 AP patients from 2011 to 2018 who underwent pancreatic stenting within 48 hours of admission. RESULTS: A total of 330 (98.2%) patients underwent successful pancreatic stenting, of whom 23 (7.0%) had severe AP, 178 (53.9%) had moderately severe AP, and 129 (39.1%) had mild AP. Visible PD obstructive material was observed in 94 (28.5%) patients. The mean oral refeeding time since admission and length of hospital stay were 3.5±2.7 and 7.4±6.7 days, respectively. Procedure-related adverse events, in-hospital mortality, and local complication rates were 0.3%, 0.3%, and 7.6%, respectively. CONCLUSIONS: Early endoscopic pancreatic stenting in AP patients effectively shortened the fasting time and length of hospital stay and did not increase the risk of adverse events, death, or local complications. A further prospective randomized controlled clinical trial is currently underway to validate the safety and efficacy of this procedure.

miR­32­5p suppresses the proliferation and migration of pancreatic adenocarcinoma cells by targeting TLDC1.

Pancreatic adenocarcinoma (PAAD) is one of the most fatal types of cancer in humans. However, the molecular mechanisms underlying the migration and invasion abilities of PAAD cells remain unclear. The aim of the present study was to explore the regulatory roles of microRNA (miR)­32­5p in PAAD cells. miR­32­5p mimic and inhibitor were used to transfect the human PAAD AsPC­1 cell line to determine the role of miR­32­5p in cell proliferation and metastasis. The starBase database predicted the binding of miR­32­5p to the target gene TBC/LysM­associated domain containing 1 (TLDC1). Further analyses were performed to assess miR­32­5p and TLDC1 expression levels in healthy and PAAD tissues, as well as the association between miR­32­5p or TLDC1 expression and the prognosis of patients with PAAD. The interaction between miR­32­5p and TLDC1 was verified using the dual­luciferase reporter assay. miR­32­5p and TLDC1 expression levels were detected by reverse transcription­quantitative PCR and western blotting, respectively. The Cell Counting Kit­8 assay was utilised to assess cell proliferation, whereas the wound­healing and Transwell assays were conducted to assess cell migration and invasion, respectively. miR­32­5p expression levels were markedly lower in PAAD tissue compared with those in healthy tissue, and were significantly lower in PAAD cell lines compared with those in the human pancreatic duct cell line HPDE6, which corresponded with poor prognosis. miR­32­5p significantly inhibited the proliferation of PAAD cells and markedly reduced migration and invasion compared with the negative controls. miR­32­5p was shown to target TLDC1, with miR­32­5p expression in PAAD being negatively correlated with TLDC1 expression. High TLDC1 expression levels were associated with a poorer prognosis compared with low TLDC1 expression levels. Co­transfection of miR­32­5p mimic and pcDNA/TLDC1 demonstrated that TLDC1 significantly reversed miR­32­5p­mediated inhibition of the proliferation, migration and invasion of PAAD cells. Overall, the present study demonstrated that miR­32­5p may serve as a tumor­suppressor gene by inhibiting the proliferation and migration and invasion of PAAD cells via the downregulation of TLDC1. Therefore, miR­32­5p may serve as a potential diagnostic or prognostic marker for PAAD.

Renewable and robust biomass waste-derived Co-doped carbon aerogels for PMS activation: Catalytic mechanisms and phytotoxicity assessment.

Developing monolithic carbon-based catalyst with low cost, easy separation and high performance to degrade pollutants via PMS activation is crucial. In this work, a series of novel monolithic Me-CA catalysts based on biomass derived carbon aerogel were prepared by hydrothermal method using waste watermelon peel as raw material. Co-CA catalyst showed excellent performance to activate PMS for 2, 4-DCP degradation in different temperature and different water matrices. Different pollutants, such as ciprofloxacin (CIP), bisphenol A (BPA), and 2, 4-dichlorophenoxyacetic acid (2, 4-D) could also be removed in the Co-CA/PMS system. As expected, Co-CA could be easily separated from degraded solution, and show high stability and reusability for PMS activation with a lower cobalt leaching. Based on the results of the quenching tests, electron paramagnetic resonance (EPR) spectra, Chronoamperometric test (i-t curves) and electro-chemical impedance spectroscopy (EIS), the PMS activation mechanism was proposed. The phytotoxicity assessment determined by germination situation of mung bean indicated that PMS activation could eliminate the hazards of 2, 4-D. Therefore, this study provides a low cost, efficient and environmental-friendly monolithic biomass carbon aerogel catalyst for different pollutants degradation, which further advances monolithic catalyst for practical wastewater treatment.

Low-voltage and fast-response SnO2nanotubes/perovskite heterostructure photodetector.

One-dimensional metal-oxides (1D-MO) nanostructure has been regarded as one of the most promising candidates for high-performance photodetectors due to their outstanding electronic properties, low-cost and environmental stability. However, the current bottlenecks are high energy consumption and relatively low sensitivity. Here, Schottky junctions between nanotubes (NTs) and FTO were fabricated by electrospinning SnO2NTs on FTO glass substrate, and the bias voltage of SnO2NTs photodetectors was as low as ∼1.76 V, which can effectively reduce energy consumption. Additionally, for improving the response and recovery speed of SnO2NTs photodetectors, the NTs were covered with organic/inorganic hybrid perovskite. SnO2NTs/perovskite heterostructure photodetectors exhibit fast response/recovery speed (∼0.075/0.04 s), and a wide optical response range (∼220-800 nm). At the same time, the bias voltage of heterostructure photodetectors was further reduced to 0.42 V. The outstanding performance is mainly attributed to the formation of type-II heterojunctions between SnO2NTs and perovskite, which can facilitate the separation of photogenerated carriers, as well as Schottky junction between SnO2NTs and FTO, which reduce the bias voltage. All the results indicate that the rational design of 1D-MO/perovskite heterostructure is a facile and efficient way to achieve high-performance photodetectors.

Energy-Saving Synthesis of Functional CoS2/rGO Interlayer With Enhanced Conversion Kinetics for High-Performance Lithium-Sulfur Batteries.

Lithium sulfur (Li-S) battery has exhibited great application potential in next-generation high-density secondary battery systems due to their excellent energy density and high specific capacity. However, the practical industrialization of Li-S battery is still affected by the low conductivity of sulfur and its discharge product (Li2S2/Li2S), the shuttle effect of lithium polysulfide (Li2Sn, 4 ≤ n ≤ 8) during charging/discharging process and so on. Here, cobalt disulfide/reduced graphene oxide (CoS2/rGO) composites were easily and efficiently prepared through an energy-saving microwave-assisted hydrothermal method and employed as functional interlayer on commercial polypropylene separator to enhance the electrochemical performance of Li-S battery. As a physical barrier and second current collector, the porous conductive rGO can relieve the shuttle effect of polysulfides and ensure fast electron/ion transfer. Polar CoS2 nanoparticles uniformly distributed on rGO provide strong chemical adsorption to capture polysulfides. Benefitting from the synergy of physical and chemical constraints on polysulfides, the Li-S battery with CoS2/rGO functional separator exhibits enhanced conversion kinetics and excellent electrochemical performance with a high cycling initial capacity of 1,122.3 mAh g-1 at 0.2 C, good rate capabilities with 583.9 mAh g-1 at 2 C, and long-term cycle stability (decay rate of 0.08% per cycle at 0.5 C). This work provides an efficient and energy/time-saving microwave hydrothermal method for the synthesis of functional materials in stable Li-S battery.

Treatment of acute pancreatitis with pancreatic duct decompression via ERCP: A case report series.

Acute pancreatitis is a common disorder in the gastrointestinal system, which is characterized by an increasing incidence and a high mortality. Currently, symptomatic treatment becomes the predominant option for the treatment of acute pancreatitis. To date, there is little knowledge on the treatment of acute pancreatitis through alleviation of pancreatic ductal hypertension and removal of pancreatic ductal obstruction. Endoscopic retrograde cholangiopancreatography (ERCP), an effective treatment for acute biliary pancreatitis, may alleviate the obstruction and edema in the common channel of the bile duct and pancreatic duct, to achieve the indirect treatment of acute pancreatitis, and may achieve the removal of intrapancreatic ductal obstruction and reduction in the intrapancreatic ductal pressure. Hereby, we report 3 cases with acute pancreatitis that were successfully treated by the pancreatic duct decompression via ERCP in one single center from China. Our data demonstrate that pancreatic duct decompression via ERCP is effective for the treatment of acute pancreatitis, which may shorten the course of acute pancreatitis through alleviating pain, shortening fasting duration and controlling the inflammatory reactions. It is recommended to use further prospective, randomized, controlled clinical trials to evaluate the efficacy and safety of pancreatic duct decompression via ERCP for acute pancreatitis.
