TaF4: A Novel Two-Dimensional Antiferromagnetic Material with a High Néel Temperature Investigated Using First-Principles Calculations.

The structural, electronic, and magnetic properties of a novel two-dimensional monolayer material, TaF4, are investigated using first-principles calculations. The dynamical and thermal stabilities of two-dimensional monolayer TaF4 were confirmed using its phonon dispersion spectrum and molecular dynamics calculations. The band structure obtained via the high-accuracy HSE06 (Heyd-Scuseria-Ernzerhof 2006) functional theory revealed that monolayer two-dimensional TaF4 is an indirect bandgap semiconductor with a bandgap width of 2.58 eV. By extracting the exchange interaction intensities and magnetocrystalline anisotropy energy in a J1-J2-J3-K Heisenberg model, it was found that two-dimensional monolayer TaF4 possesses a Néel-type antiferromagnetic ground state and has a relatively high Néel temperature (208 K) and strong magnetocrystalline anisotropy energy (2.06 meV). These results are verified via the magnon spectrum.

Nanometer-Resolved Mapping of Organic Cation Migration Behavior in Methylammonium Lead Halide Perovskites.

The performance and stability of organic metal halide perovskite (OMHP) optoelectronic devices have been associated with ion migration. Understanding of nanoscale resolved organic cation migration mechanism would facilitate structure engineering and commercialization of OMHP. Here, we report a three-dimensional approach for in situ nanoscale infrared imaging of organic ion migration behavior in OMHPs, enabling to distinguish migrations along grain boundary and in crystal lattice. Our results reveal that organic cation migration along OMHP film surface and grain boundaries (GBs) occurs at lower biases than in crystal lattice. We visualize the transition of organic cation migration channels from GBs to volume upon increasing electric field. The temporal resolved results demonstrate the fast MA+ migration kinetics at GBs, which is comparable to diffusivity of halide ions. Our findings help understand the role of organic cations in the performance of OMHP devices, and the proposed approach holds broad applicability for revealing migration mechanisms of organic ions in OMHPs based optoelectronic devices.

Fluorinated organic ammonium salt passivation for high-efficiency and stable inverted CsPbI2Br perovskite solar cells.

All-inorganic CsPbI2Br inverted perovskite solar cells (PSCs) have drawn increasing attention because of their outstanding thermal stability and compatible process with tandem cells. However, relatively low open circuit voltage (Voc) has lagged their progress far behind theoretical limits. Herein, we introduce phenylmethylammonium iodide and 4-trifluoromethyl phenylmethylammonium iodide (CFPMAI) on the surface of a CsPbI2Br perovskite film and investigate their passivation effects. It is found that CFPMAI with a -CF3 substituent significantly decreases the trap density of the perovskite film by forming interactions with the under-coordinated Pb2+ ions and effectively suppresses the non-radiative recombination in the resulting PSC. In addition, CFPMAI surface passivation facilitates the optimization of energy-level alignment at the CsPbI2Br perovskite/[6,6]-phenyl C61 butyric acid methyl ester interface, resulting in improved charge extraction from the perovskite to the charge transport layer. Consequently, the optimized inverted CsPbI2Br device exhibits a markedly improved champion efficiency of 14.43% with a Voc of 1.12 V, a Jsc of 16.31 mA/cm2, and a fill factor of 79.02%, compared to the 10.92% (Voc of 0.95 V) efficiency of the control device. This study confirms the importance of substituent groups on surface passivation molecules for effective passivation of defects and optimization of energy levels, particularly for Voc improvement.

Stable room-temperature ferromagnetism and gate-tunable quantum anomalous Hall effect of two-dimensional 5d transition-metal trihalide OsX3 (X = Cl, Br, I) monolayers.

5d transition-metal compounds are usually not expected to exhibit distinct magnetic ordering owing to their substantial binding energy associated with 5d electrons. In this study, we demonstrate that two-dimensional (2D) 5d transition-metal Os trihalide OsX3 monolayers can exhibit room-temperature ferromagnetism and quantum anomalous Hall effect (QAHE) by utilizing density functional theory and Monte Carlo simulation. Our calculation results of coexisting Raman and infrared activities of lattice vibration reveal the structural stability of 2D OsX3 (X = Cl, Br, I) and structural instability of 2D OsX3 (X = F). Furthermore, all 2D OsX3 trihalides (X = Cl, Br, I) are half-metals, and their ferromagnetism remains stable under ambient temperature, where 2D OsCl3 and OsBr3 have an in-plane easy axis while 2D OsI3 has an out-of-plane easy axis. Notably, when spin-orbit coupling is included, the gate-tunable QAHE could emerge in ferromagnetic 2D OsI3, while 2D OsCl3 and OsBr3 are topologically trivial. Additionally, the magnon bands of 2D OsX3 (X = Cl, Br, I) possess two spin-wave branches with dispersion similar to that of the Dirac cone in the electronic structure of graphene, which are attributed to the unique ferromagnetic honeycomb sublattice of osmium atoms.

Atomic Force Microscopy-Based Nanoscale Infrared Techniques for Catalysis.

Atomic force microscopy (AFM)-based nanoscale infrared (nano-IR) techniques have found extensive application in the fields of chemistry, physics, and materials science, enabling the visualization of nanoscale features that surpass the optical diffraction limit. More recently, tentative investigations have been conducted into the use of these techniques in the field of catalysis, particularly in studying interfacial processes involving molecular monolayer samples. IR nanoimaging and nanospectroscopy offer unique perspectives on catalytic processes. Considering the specific characteristics of catalytic processes, this Perspective highlights the need for and reviews the current status of AFM-based nano-IR techniques for catalysis investigations, which aims to contribute to a deeper understanding of the nanoscale mechanisms underlying the catalytic processes.

Progress and Prospects in Metallic FexGeTe2 (3 ≤ x ≤ 7) Ferromagnets.

Thermal fluctuations in two-dimensional (2D) isotropy systems at non-zero finite temperatures can destroy the long-range (LR) magnetic order due to the mechanisms addressed in the Mermin-Wanger theory. However, the magnetic anisotropy related to spin-orbit coupling (SOC) may stabilize magnetic order in 2D systems. Very recently, 2D FexGeTe2 (3 ≤ x ≤ 7) with a high Curie temperature (TC) has not only undergone significant developments in terms of synthetic methods and the control of ferromagnetism (FM), but is also being actively explored for applications in various devices. In this review, we introduce six experimental methods, ten ferromagnetic modulation strategies, and four spintronic devices for 2D FexGeTe2 materials. In summary, we outline the challenges and potential research directions in this field.

Large-scale fabrication and Mo vacancy-induced robust room-temperature ferromagnetism of MoSe2 thin films.

Molybdenum selenide (MoSe2) has recently attracted particular attention due to its room-temperature ferromagnetism (RTFM) and related spintronic applications. However, not only does the FM mechanism of MoSe2 remain controversial, but also the synthesis of MoSe2 thin films with robust RTFM is still an unmet challenge. Here it is shown that using polymer-assisted deposition under appropriate growth conditions, large-scale (4 cm × 4 cm) synthesis of MoSe2 thin films with robust RTFM and a smooth surface (roughness average ∼0.22 nm) is possible. A new record-high saturation magnetization (6.69 emu g-1) is achieved in the prepared MoSe2 thin films, about 5 times the previously reported record (1.39 emu g-1) obtained in 2H-MoSe2 nanoflakes. Meanwhile, the coercivity of the MoSe2 films can be tuned down to a new record-low value (5.0 Oe), one-tenth of the previously reported record. Notably, detailed analysis combining the experimental findings and calculation results shows that the robust RTFM mainly comes from the Ruderman-Kittel-Kasuya-Yoshida (RKKY) interaction between the magnetic moments induced by abundant Mo vacancies (VMos) in the MoSe2 films. Our results give insights into the large-scale production and robust RTFM of MoSe2 thin films and may provide a platform for designing and fabricating spintronic materials and devices based on transition-metal dichalcogenides.

Objective To screen antigen targets for immunotherapy by analyzing over-expressed genes, and to identify significant pathways and molecular mechanisms in esophageal cancer by using bioinformatic methods such as enrichment analysis, protein-protein interaction (PPI) network, and survival analysis based on the Gene Expression Omnibus (GEO) database.Methods By screening with highly expressed genes, we mainly analyzed proteins MUC13 and EPCAM with transmembrane domain and antigen epitope from TMHMM and IEDB websites. Significant genes and pathways associated with the pathogenesis of esophageal cancer were identified using enrichment analysis, PPI network, and survival analysis. Several software and platforms including Prism 8, R language, Cytoscape, DAVID, STRING, and GEPIA platform were used in the search and/or figure creation.Results Genes MUC13 and EPCAM were over-expressed with several antigen epitopes in esophageal squamous cell carcinoma (ESCC) tissue. Enrichment analysis revealed that the process of keratinization was focused and a series of genes were related with the development of esophageal cancer. Four genes including ALDH3A1, C2, SLC6A1,and ZBTB7C were screened with significant P value of survival curve.Conclusions Genes MUC13 and EPCAM may be promising antigen targets or biomarkers for esophageal cancer. Keratinization may greatly impact the pathogenesis of esophageal cancer. Genes ALDH3A1, C2, SLC6A1,and ZBTB7C may play important roles in the development of esophageal cancer.

Clinical analysis of liver dysfunction induced by SHR-1210 alone or combined with apatinib and chemotherapy in patients with advanced esophageal squamous cell carcinoma / 中华肿瘤杂志

Objective: To investigate the clinical characteristics of abnormal liver function in patients with advanced esophageal squamous carcinoma treated with programmed death-1 (PD-1) antibody SHR-1210 alone or in combination with apatinib and chemotherapy. Methods: Clinical data of 73 patients with esophageal squamous carcinoma from 2 prospective clinical studies conducted at the Cancer Hospital Chinese Academy of Medical Sciences from May 11, 2016, to November 19, 2019, were analyzed, and logistic regression analysis was used for the analysis of influencing factors. Results: Of the 73 patients, 35 had abnormal liver function. 13 of the 43 patients treated with PD-1 antibody monotherapy (PD-1 monotherapy group) had abnormal liver function, and the median time to first abnormal liver function was 55 days. Of the 30 patients treated with PD-1 antibody in combination with apatinib and chemotherapy (PD-1 combination group), 22 had abnormal liver function, and the median time to first abnormal liver function was 41 days. Of the 35 patients with abnormal liver function, 2 had clinical symptoms, including malaise and loss of appetite, and 1 had jaundice. 28 of the 35 patients with abnormal liver function returned to normal and 7 improved to grade 1, and none of the patients had serious life-threatening or fatal liver function abnormalities. Combination therapy was a risk factor for patients to develop abnormal liver function (P=0.007). Conclusions: Most of the liver function abnormalities that occur during treatment with PD-1 antibody SHR-1210 alone or in combination with apatinib and chemotherapy are mild, and liver function can return to normal or improve with symptomatic treatment. For patients who receive PD-1 antibody in combination with targeted therapy and chemotherapy and have a history of long-term previous smoking, alcohol consumption and hepatitis B virus infection, liver function should be monitored and actively managed in a timely manner.

Interface Engineering of Cu(In,Ga)Se2 Solar Cells by Optimizing Cd- and Zn-Chalcogenide Alloys as the Buffer Layer.

The optimization of band alignment at the buffer/absorber interface is realized by tuning compositions of Cd and Zn chalcogenides as the buffer layer toward high-efficiency Cu(In,Ga)Se2 (CIGS) solar cells. Using the special quasi-random structure (SQS) approach, we construct randomly disordered ZnxCd1-xSySe1-y alloys and ZnSxO1-x alloys as alternatives to the traditional CdS buffer layer. The compositional dependence of formation energies, lattice parameters, band-gap energies, and band alignments of ZnxCd1-xSySe1-y and ZnSxO1-x alloys is investigated by first-principles density functional theory calculations. For quaternary ZnxCd1-xSySe1-y alloys, we find that the miscibility temperatures and the bandgap bowing coefficients are proportional to the lattice mismatch between the mixing elements. The linear dependence of lattice parameters, trinomial dependence of band-gap energies and band-edge positions on the alloy-composition of ZnxCd1-xSySe1-y alloys are established. For ZnSxO1-x alloys, we find the lattice parameters also exhibit a linear dependence on its composition. Because of the large lattice mismatch and the chemical disparity between ZnO and ZnS, the bowing coefficient for the bandgap energies of ZnSxO1-x alloys is composition dependent, and is larger for dilute ZnSxO1-x alloys. With the optimization criteria of moderate spike-like conduction band offset, large valance band offset, sufficiently wide bandgap, and lattice match with respect to the CIGS absorber, we illustrate the optimal composition range of both ZnxCd1-xSySe1-y alloys and ZnSxO1-x alloys as the buffer layer of the CIGS solar cells. Our work demonstrates that ZnxCd1-xSySe1-y alloys and ZnSxO1-x alloys are promising buffer layers for high-efficiency CIGS solar cells.

Less immediate postoperative pain and bleeding were reported. Patients were followed up for an average of 10 months (range, 6 to 21 months). There were no cases of major malpositions, double-bubble and bottom out symptoms. The overall outcome was with better symmetry and satisfaction with time passed by, and no secondary surgical procedures needed.Conclusions:Primary and satisfactory results have been obtained in subfascial breast augmentation and restoration for indications. With the endoscopic-assisted accurate pectoral fascial dissection, and well reserved soft tissue coverage, this technique could avoid the pectoralis major muscle ablation and keep the advantages of sub-glandular plane.

Impact of aesthetic suture techniques training in improving the suture quality of non-plastic surgeons / 中华医学美学美容杂志

Objective:To investigate the effect and necessity of aesthetic suture techniques training in improving the suture quality of non-plastic surgeons.Methods:The well-planned aesthetic suture techniques training programs were run in non-plastic surgery senior residents and attending surgeons at Peking University People＇s Hospital from January 2017 to January 2019. There were 120 senior residents and attending surgeons included (aged from 25-32 years, average 28.9 years, with 66 males and 54 females). Mixed teaching methods were used such as video shows, lectures, surgery live show and scenario simulation. Baseline tests were taken before the training. Suture quality tests were taken when the trainings came to the end. Self-assessments were carried out both before and after the trainings.Results:Eight rounds of aesthetic suture techniques training were accomplished and 120 trainees were included in all. One hundred and two trainees passed the test while eight failed, while 10 trainees were absent in some courses or the final test. The passing rate was 85.0%. The scales of suture tools and material selection, incision design, subcutaneous tissue suture quality, tension relaxation, aesthetic suture appearance, and flexibility of different suture techniques were sharply improved after the training in both subjective and objective assessments.Conclusions:The aesthetic suture techniques training is effective in improving the suture quality of non-plastic surgeons, which is worthy to generalize in resident training.

Defect Dynamic Model of the Synergistic Effect in Neutron- and γ-Ray-Irradiated Silicon NPN Transistors.

A defect dynamic model is proposed for the positive synergistic effect of neutron- and γ-ray-irradiated silicon NPN transistors. The model considers a γ-ray-induced transformation and annihilation of the neutron-induced divacancy defects in the p-type base region of the transistor. The derived model of the base current predicts a growth function of the γ-ray dose that approaches exponentially an asymptotic value, which depends linearly on the neutron-induced initial displacement damage (DD) and a linear decay function of the dose whose slope depends quadratically on the initial DD. Variable fluence and dose neutron-γ-ray irradiation experiments are carried out, and we find all of the novel dose and fluence dependence predicted by the proposed model are confirmed by the measured data. Our work, hence, identifies that the defect evolution under γ-ray irradiation, rather than the widely believed interface Coulomb interaction, is the dominating mechanism of the synergistic effect. Our work also paves the way for the modification of displacement defects in silicon by γ-ray irradiation.

Mn(ii) chelate-coated superparamagnetic iron oxide nanocrystals as high-efficiency magnetic resonance imaging contrast agents.

In this communication, a paramagnetic bifunctional manganese(ii) chelate ([Mn(Dopa-EDTA)]2-) containing a catechol group is designed and synthesized. The catechol can bind iron ions on the surface of superparamagnetic iron oxide (SPIO) nanocrystals to form core-shell nanoparticles. Both 4 and 7 nm SPIO@[Mn(Dopa-EDTA)]2- show good water solubility, single-crystal dispersion, and low cytotoxicity. The study of the interplay between the longitudinal and transverse relaxation revealed that 4 nm SPIO@[Mn(Dopa-EDTA)]2- with lower r 2/r 1 = 1.75 at 0.5 T tends to be a perfect T 1 contrast agent while 7 nm SPIO@[Mn(Dopa-EDTA)]2- with a higher r 2/r 1 = 15.0 at 3.0 T tends to be a T 2 contrast agent. Interestingly, 4 nm SPIO@[Mn(Dopa-EDTA)]2- with an intermediate value of r 2/r 1 = 5.26 at 3.0 T could act as T 1-T 2 dual-modal contrast agent. In vivo imaging with the 4 nm SPIO@[Mn(Dopa-EDTA)]2- nanoparticle shows unique imaging features: (1) long-acting vascular imaging and different signal intensity changes between the liver parenchyma and blood vessels with the CEMRA sequence; (2) the synergistic contrast enhancement of hepatic imaging with the T 1WI and T 2WI sequence. In summary, these Fe/Mn hybrid core-shell nanoparticles, with their ease of synthesis, good biocompatibility, and synergistic contrast enhancement ability, may provide a useful method for tissue and vascular MR imaging.

Exploration and practice of Wechat-based patient signature for paperless medical records against COVID-19 / 中华医院管理杂志

December 2019 witnessed the outbreak of COVID-19 in Wuhan city. Tongji Hospital, as a designated hospital for treatment of critical patients, shoulders the diagnosis and treatment tasks of numerous critical patients of COVID-19.For the purpose of handling their medical records and effectively preventing the nosocomial infection of the disease, the hospital put in place both the electronic signature system of patients based on a Wechat applet and a paperless medical record total solution based on the data center. These measures overcome the challenges incurred by patients′ signature on paper-based records and medical records archiving during the epidemic. On the other hand, they can not only downsize the paper-based medical records, minimize the risk of infection caused by paper-based medical records via physical contacts, but also effectively save the hospital of its operating costs and improve its efficiency of clinical work.

A Clinical Case of Breast Reconstruction with Greater Omentum Flap for Treatment of Upper Extremity Lymphedema.

Patients presenting with complications regarding breast cancer surgery require individualized surgical protocol for correction and reconstruction. This clinical case summarizes our clinical experience in the application of the free greater omentum flap for treatment of upper extremity lymphedema and breast reconstruction. This method combines aesthetic reconstruction of the breast with functional correction. The presented clinical vignette features a patient with post-biquadrantectomy upper extremity lymphedema. A free greater omentum flap was chosen for the purpose of breast reconstruction and vascularized lymph node transfer to treat upper extremity lymphedema. Upper extremity circumferences were monitored before and after surgical correction. The revascularized flap survived well after the operation and the reconstructed breast had a natural appearance. Six months after the operation, the patient's upper extremity circumferences decreased significantly, and the pain and swelling were also alleviated. The patient was satisfied with the results. The use of the free greater omentum flap for breast reconstruction and treatment of upper extremity lymphedema provides both aesthetic and functional patient rehabilitation. The application of this technique requires proper patient selection and thorough surgical planning.

To investigate the possibility of microsurgical anastomosis of artery, vein and lymphat-ic vessel under 3-dimension screen without eyepiece. Methods During March, 2019, 2 cases (48 and 62 years old) were operated for breast reconstruction, chest wall deformity modified, and axillary scar contracture release, under 3-dimension screen without eyepiece.Deep epigastric artery perforators (artery and vein) dissections were carried on, and microsurgical anastomosis of artery, vein and lymphatic vessel were finished. Coupler was used to do the end-to-end anastomosis of veins (2.5 mm), interrupted suture end-to-end anastomosis with 9-0 nylon for artery (2.0 mm). Reverse arm lymphatic dynamic fluorescence methylene blue tracer under Near Infrared Imaging was used to test the func-tion of lymphatic system. The ends of 2 dominant drainage lymphatic vessels was found in the released axillary area (0.2 mm and 0.3 mm, respectively), and were anastomosis to the vein (0.5 mm) of lateral chest lymphatic tissue.Im-mediate methylene blue tracer under near infrared imaging was used to confirm the patency of lymphatic vessels-veins anastomosis and follow-up post operation. Flap were monitored use HHD. Results Two patients recovered well, and the flaps survived completely with appreciated appearances. The lymphedema of the arms were getting better, the peripheral diameter was reduced by about 2.0 cm compared with that before operation. Conclusion The technique of microsurgical anastomosis of artery, vein and lymphatic vessel without eyepiece under 3-dimension screen is possi-ble and safe.

All patients were satisfied with the aesthetic and functional outcomes.@*Conclusions@#The technique of Pacman flap is a simple and effective method to repair the skin and soft tissue defects.

Analysis of satisfaction and quality of life of 54 patients after breast reconstruction: a retrospective study / 中华整形外科杂志

Objective@#This is a study to evaluate complication rate, satisfaction and quality of life after breast reconstruction under different classifications. The classification criteria are the timing of operation, surgical procedures, and patients′age.@*Methods@#By reviewing the surgical cases from August 2004 to June 2018, the authors summarized the data of 102 patients with breast reconstruction of the same surgeon in Peking University People′s Hospital and Plastic Surgery Hospital (Institute) CAMS PUMC. Fifty-four patients who met the inclusion criteria and completed the BREAST-Q breast reconstruction module scale, were divided into immediate group or delayed group, according to the timing of operation; divided into abdomen group or other procedures group, according to the surgical procedure; and divided into the young patients′group or senior patients′group according to age. The index were (1) postoperative complication rate, (2)satisfaction with breasts, psychosocial well-being, physical well-being of chest and abdomen, sexual well-being, satisfaction with outcome, satisfaction with information, satisfaction with care (based on the BREAST-Q scale).@*Results@#Complication rate was 9.1%(1/11) in the immediate group, 16.3%(7/43) in the delayed group, 14.7%(5/34) in the abdomen group, 15.0%(3/20) in other procedures group, 13.6%(3/22) in the young patients′group, and 15.6%(5/32) in the senior patients′group. There was no significant difference in the incidence of complications (P>0.05). The postoperative scores of satisfaction with breasts, psychological well-being and sexual well-being were significantly higher in the immediate group than in the delayed group(P=0.026, P<0.001 and P=0.001, respectively). The score of postoperative physical well-being of chest was significantly higher in the abdomen group than other procedures group(P=0.020). The score physical well-being of abdomen was lower compared with the preoperative in the abdomen group (P<0.001). The score of physical well-being of abdomen was lower in the senior patients′group than that of the young patients′group (P=0.010).@*Conclusions@#The complication incidence of breast reconstruction patients was similar among different groups. The breast reconstruction surgery can significantly improve satisfaction and quality of life of patients. To some extent, immediate breast reconstruction can reduce the psychological and physiological effects of breast loss on patients, leading to higher postoperative satisfaction. Breast reconstruction with abdominal flaps can provide patients with better chest health but poor abdomen health. Although elderly patients undergoing breast reconstruction will have poor physical well-being of abdomen, they can still achieve higher satisfaction of operation.
