Abstract The ternary compound semiconductor Cu 2 SnS 3 (CTS) is formed from non‐toxic materials that are abundant in Earth's crust and other low‐cost elements. CTS has also been reported to a band gap energy range of 0.93–1.77 eV an absorption coefficient 1.0×10 4 cm –1 . Consequently, potential material for the p‐type absorber layer thin film solar cells. In this study, we examined dependence optical, electrical photovoltaic properties films on Cu/Sn composition ratio. were fabricated by...
Antimelanoma differentiation‐associated protein (anti‐MDA)5 antibodies are associated with rapidly progressive interstitial lung disease (RP‐ILD) in patients clinically amyopathic dermatomyositis (CADM) or (DM). We aimed to evaluate the relevance of monitoring anti‐MDA5 antibody levels for management RP‐ILD CADM DM. Twelve (n = 10) DM 2) accompanied by were included. Baseline characteristics and outcomes recorded. Serial measurements measured. All treated corticosteroids, tacrolimus...
Abstract Cu 2 ZnSnS 4 (CZTS) thin films were prepared by sulfurization of electrodeposited Cu‐Zn‐Sn precursors. The precursors deposited on Mo‐coated glass substrates in a one‐step process from an electrolyte containing copper (II) sulfate pentahydrate, zinc heptahydrate, tin chloride dehydrate and tri‐sodium citrate dehydrate. sulfurized annealing with sulfur at temperatures 580 °C 600 N atmosphere. X‐ray diffraction peaks attributable to CZTS detected the films. Photovoltaic cells...
We report on the sulfurization of metal-alloyed precursors in Cu2SnS3 (CTS)-based thin-film solar cells. CTS thin films were prepared through Cu–Sn alloy at temperatures 500–580 °C for 2 h a N2 atmosphere with sulfur vapor. The Cu/Sn composition ratios sulfurized determined by X-ray fluorescence analysis to be range 1.77–1.89. photovoltaic properties CTS-based cells improved increasing temperature owing higher external quantum efficiency long wavelengths. cell comprising film 580 exhibited...
The ternary compound Cu 2 SnS 3 (CTS) is composed of elements that are low in cost, non‐toxic, and abundant the Earth's crust. In addition, CTS a p‐type semiconductor with high reported absorption coefficient more than 10 4 cm −1 band gap energy 0.92–1.77 eV. It is, therefore, considered to be suitable candidate for absorber layer thin film solar cells. present study, films were produced by first depositing precursor co‐evaporation Cu, Sn, S, then annealing them. Solar cells fabricated using...
Mammalian mRNAs are generated by complex and coordinated biogenesis pathways acquire 5′-end m7G caps that play fundamental roles in processing translation. Here we show several selenoprotein not recognized efficiently translation initiation factor eIF4E because they bear a hypermethylated cap. This cap modification is acquired via maturation pathway similar to of the small nucle(ol)ar RNAs (sn- snoRNAs). Our findings also establish trimethylguanosine synthase 1 (Tgs1) interacts with for...
Selenoproteins contain the amino acid selenocysteine which is encoded by a UGA Sec codon. Recoding requires complex mechanism, comprising cis-acting SECIS RNA hairpin in 3′UTR of selenoprotein mRNAs, and trans-acting factors. Among these, Binding Protein 2 (SBP2) central to mechanism. SBP2 has been so far functionally characterized only rats humans. In this work, we report characterization Drosophila melanogaster (dSBP2). Despite its shorter length, it retained same synthesis-promoting...
In this paper, the effects of geometric imperfections on nonlinear buckling behavior rigidly jointed single-layer lattice domes under vertical loading have been studied. A commercially available finite-element code has used. Numerical experiments using varying levels imperfection, chosen to be same forms as various linear eigenmodes, demonstrated complexity behavior. Lower bounds imperfection sensitivity elastic overall loads shown result from reduced stiffness analysis which is a simple...
The binding potencies of OCT to chick intestinal calcitriol receptor and vitamin DBP were approximately 1/8 1/600 the respective values calcitriol. is circulating mainly as an intact form bound chylomicrons and/or lipoproteins. Intravenously injected [3H]-OCT normal rats was quickly decreased from blood rapid excretion a glucuronate into bile observed. However, significant amounts radioactivities recovered in liver intestine even after 24 h. separation calcemic immune differentiation...
Cu 2 SnS 3 (CTS) is a promising compound for use as an absorber layer in thin‐film solar cells because it made up of low‐cost and abundant elements. However, the band gap energy 0.94 eV monoclinic less than optimal value layers single‐junction cells. On other hand, GeS (CGS) approximately 1.5–1.6 eV. Therefore, this study, we carried out synthesis Sn 1− x Ge S , which solid solution . The structure prepared samples was investigated using X‐ray diffraction Raman analyses. Diffuse reflectance...
A novel vitamin D3 analogue, [2 beta-(3-hydroxypropoxy)-calcitriol: ED-71] showed a similar Ca-regulating activity as calcitriol in the vivo and vitro Ca mobilization test ex intestinal absorption assay using D-deficient rats. The differentiation-inducing of ED-71 mouse myeloid leukemia cell line (WEHI-3 cell) was slightly less than that calcitriol. distributes predominantly plasma an intact form its half-life twice long Further study revealed higher binding potency to plasma-specific...
Among more than 20 yeast strains isolated from the traditional starter "murcha" in Nepal, we characterized a that might be involved saccharification. This strain, identified as Pichia burtonii, produced an extracellular amylolytic enzyme when cultured presence of starch medium. Since no amylase secreted by P. burtonii has yet been reported, purified and determined its N-terminal amino acid sequence. Together with results hydrolyzing activity assay toward various substrates, it was found to...
Liquid embolic agents are widely used for the endovascular embolization of vascular conditions. However, based on phase transition is limited by adhesion microcatheter to agent, use an organic solvent, unintentional catheter retention, and other complications. By mimicking thrombus formation, a water-soluble polymer that rapidly glues blood into gel without triggering coagulation was developed. The polymer, which consists cationic aromatic residues with adjacent sequences, shows...
