A typical high-e fficiency solar cell device needs the best lattice matching between different constituent layers to mitigate the open-circuit voltage loss. In the present work, the physical properties of Cds thin films are investigated where films with 100 nm thickness were fabricated on the different types of substrates viz. soda–lime glass, indium-doped tin oxide(ITO)-and fl uorine-doped tin oxide(FTO)-coated glass substrates, and silicon wafer using electron beam evaporation. The X-ray diffraction patterns confirmed that deposited thin films showed cubic phase and had(111) as predominant orientation where the structural parameters were observed to be varied with nature of substrates. The ohmic behaviour of the Cds films was disclosed by current–voltage characteristics, whereas the scanning electron microscopy micrograph revealed the uniform deposition of the Cds films with the presence of round-shaped grains. The elemental analysis confirmed the Cds films deposition where the Cd/s weight percentage ratio was changed with nature of substrates. The direct energy band gap was observed in the 1.63–2.50 eV range for the films grown on different substrates. The investigated properties of thin Cds layers demonstrated that the selection of substrate(in terms of nature) during device fabrication plays a crucial role.

There is a strong evidence supporting the hypothesis of synaptic dysfunction as a major contributor to neural circuit and network disruption underlying emotional and mood dysregulation in psychiatric disorders(simmons et al.,2024).Diverse sets of distinct molecular signaling pathways converge on the synapse to regulate synaptogenesis,synaptic function,and synaptic plasticity in brain regions and circuits through complex interactions organized by numerous multivalent protein scaffolds,including the family of proteins known as A-kinase anchoring proteins(AKAPs).

Chinese utilities as well as those worldwide are facing increased demand for additional electricity, reduced plant emissions and greater efficiency. To meet this challenge will require increasing boiler temperature, pressure and coal ash corrosion resistance of the materials of boiler construction of future coal-fired boilers. A new nickel-based tube alloy, INCONEl^R alloy 740, is described aiming at meeting this challenge. Emphasis will be on describing the alloy＇ s mechanical properties, coal-ash and steam corrosion resistance. Microstructural stability as a function of temperature and time is addressed as well as some of the early methodology em- ployed to arrive at the current chemical composition.

A highly selective and sensitive liquid chromatography-tandem mass spectrometry （lC-Ms/Ms） assay has been described for the determination of asenapine （AsE） in presence of its inactive metabolites N-desmethyl asenapine （DMA） and asenapine-N-glucuronide （AsG）. AsE, and AsE 13C-d3, used as internal standard （Is）, were extracted from 300 μl human plasma by a simple and precise liquid-liquid extraction procedure using methyl tert-butyl ether. Baseline separation of AsE from its inactive metabolites was achieved on Chromolith Performance RPse （100 mm ×4.6 mm） column using acetonitrile- 5.0 mM ammonium acetate-10% formic acid （90：10：0.1, v/v/v） within 4.5 min. Quantitation of AsE was done on a triple quadrupole mass spectrometer equipped with electrospray ionization in the positive mode. The protonated precursor to product ion transitions monitored for AsE and AsE 13C-d3 were m/z 286.1 → 166.0 and m/z 290.0 → 166.1, respectively. The limit of detection （lOD） and limit of quantitation （lOQ） of the method were 0.0025 ng/ml and 0.050 ng/ml respectively in a linear concentration range of 0.050-20.0 ng/ml for AsE. The intra-batch and inter-batch precision （% CV） and mean relative recovery across quality control levels were 〈 5.8% and 87.3%, respectively. Matrix effect, evaluated as Is-normalized matrix factor, ranged from 1.03 to 1.05. The stability of AsE under different storage conditions was ascertained in presence of the metabolites. The developed method is much simpler, matrix free, rapid and economical compared to the existing methods. The method was suc- cessfully used for a bioequivalence study of asenapine in healthy Indian subjects for the first time.

Piezoelectric resonators with mechanical damping and resistance in current conduction

引用

science China(Physics,Mechanics & Astronomy) 2007年第5期50卷 650-672页

作者： Yook-Kong YONG Mihir s patel Department of Civil and Environmental Engineering Rutgers University Piscataway NJ 08854 USA

A novel design method for high Q piezoelectric resonators was presented and proposed using the 3-D equations of linear piezoelectricity with quasi-electrostatic approximation which include losses attributed to mechanical damping in solid and resistance in current conduction. There is currently no finite element software for estimating the Q of a resonator without apriori assumptions of the resonator im- pedance or damping. There is a necessity for better and more realistic modeling of resonators and filters due to miniaturization and the rapid advances in frequency ranges in telecommunication. We presented new three-dimensional finite element models of quartz and barium titanate resonators with mechanical damping and resistance in current conduction. lee, liu and Ballato’s 3-D equations of linear piezoelectricity with quasi-electro- static approximation which include losses attributed to mechanical damping in solid and resistance in current conduction were formulated in a weak form and implemented in COMsOl. The resulting finite element model could predict the Q and other electrical parameters for any piezoelectric resonator without apriori as- sumptions of damping or resistance. Forced and free vibration analyses were per- formed and the results for the Q and other electrical parameters were obtained. Comparisons of the Q and other electrical parameters obtained from the free vibra- tion analysis with their corresponding values from the forced vibration analysis were found to be in excellent agreement. Hence, the frequency spectra obtained from the free vibration analysis could be used for designing high Q resonators. Results for quartz thickness shear AT-cut and sC-cut resonators and thickness stretch poled barium titanate resonators were presented. An unexpected benefit of the model was the prediction of resonator Q with energy losses via the mounting supports.

A selective, sensitive and rugged liquid chromatography–tandem mass spectrometry(lC–Ms/Ms) assay has been developed for the simultaneous determination of doxepin(Dox) and its pharmacologically active metabolite, nordoxepin(NDox) in human plasma. The analytes and their internal standards(Is)were extracted from 500 m l of human plasma by liquid-liquid extraction using methyl tert-butyl *** separation was achieved on Hypurity C8 column(100 mm ? 4.6 mm, 5 mm) using a mixture of acetonitrile-methanol(95:5, v/v) and 2.0 mM ammonium formate in 93:7(v/v) ratio. Detection was accomplished by tandem mass spectrometry in the positive ionization and multiple reaction monitoring acquisition mode. The protonated precursor to product ion transitions studied for Dox, NDox,and their corresponding Iss, propranolol and desipramine, were m/z 280.1-107.0, 266.0-107.0,260.1-116.1 and 267.1-72.1, respectively. A linear dynamic range of 15.0–3900 pg/ml for Dox and 5.00–1300 pg/ml for NDox was established with mean correlation coefficient(r2) of 0.9991 and 0.9993, respectively. The extraction recovery ranged from 86.6%–90.4% and 88.0%–99.1% for Dox and NDox, respectively. The intra-batch and inter-batch precision(% CV) across quality control levels was r 8.3% for both the analytes. stability evaluated under different storage conditions showed no evidence of degradation and the % change in stability samples compared to nominal concentration ranged from 4.7% to12.3%. The method was successfully applied to a bioequivalence study of 6 mg doxepin hydrochloride orally disintegrating tablet in 41 healthy Indian subjects under fasting and fed conditions.
