Generation of Schrödinger Cat States in a Hybrid Cavity Optomechanical System.

We present an alternative scheme to achieve Schrödinger cat states in a strong coupling hybrid cavity optomechanical system. Under the single-photon strong-coupling regime, the interaction between the atom-cavity-oscillator system can induce the mesoscopic mechanical oscillator to Schrödinger cat states. Comparing to previous schemes, the proposed proposal consider the second order approximation on the Lamb-Dicke parameter, which is more universal in the experiment. Numerical simulations confirm the validity of our derivation.

Catalytic co-pyrolysis behaviors and kinetics of camellia shell and take-out solid waste using pyrolyzer - gas chromatography/mass spectrometry and thermogravimetric analyzer.

The influences of operating temperature, catalyst types and mixing ratios on co-pyrolysis of camellia shell (CS) and take-out solid waste (TSW) were investigated through orthogonal experiments design. The target was to gain more aliphatic hydrocarbons and monocyclic aromatic hydrocarbons (MAHs) and reduce the production of acids. According to orthogonal experiments results, higher temperature contributed to generate aliphatic hydrocarbons and inhibit formation of acids. Combined utilization of HZSM-5 and CaO was effective to obtain more MAHs and reduce acids. With the improvement of proportion of TSW, the yield of aliphatic hydrocarbons increased and acids decreased. The mixing ratio of CS and TSW was 3:7, 700 °C was chosen as operating temperature and combined utilization of HZSM-5 and CaO were identified. The apparent activation energy (Eave) of CS, TSW and their blends were calculated. 3CS7TSW had the lowest Eave which were 165.33 kJ/mol (by OFW) and 163.14 kJ/mol (by KAS).

A study on catalytic co-pyrolysis of kitchen waste with tire waste over ZSM-5 using TG-FTIR and Py-GC/MS.

Co-pyrolysis characteristics of kitchen waste (KW) with tire waste (TW) were studied by TGA-FTIR and Py-GC/MS. The kinetic parameters were calculated by Ozawa-Flynn-Wall (OFW) and the Kissinger-Akahira-Sunose (KAS) methods. TGA-FTIR results indicated that CO2, CO, NO, NH3, SO2, CH and CC groups were the main gases released from the pyrolysis process, finding that a certain coupling synergistic interaction occurred between KW and TW. Co-pyrolysis of KW and TW displayed positive synergy in pyrolysis kinetics, especially at the ratio of 5:5 whose apparent activation energy declined 16.78% (by FWO) and 17.54% (by KAS). The Py-GC/MS results found that co-pyrolysis could increase the total peak area of volatile matters (10.92-15.34%). Moreover, co-pyrolysis could increase hydrocarbons (especially for olefins (13.25-37.42%)) and inhibit non-hydrocarbon compounds (about 63%) of volatile products. In brief, co-pyrolysis of KW and TW could be a potential way for improving quality of pyrolysis oil.
