Improvement of Visible a-SiC:H Based p-i-n Type-Film LED Characteristics by Hydrogen Passivation
No full textImprovement of amorphous-carbon active-layer thin-film light-emitting diodes using room-temperature ultrasound treatment
No full textUltrasound treatment (UST) applied at room temperature enhances electroluminescent intensity (maximum at 600 nm) and optical output in thin-film light-emitting diodes with hydrogenated amorphous-carbon as an active layer. This positive UST effect is attributed to a reduction of the diode series resistance caused by a change of the interface and contact resistances. The UST effect is saturated with increase of the ultrasound amplitude. (C) 1999 American Institute of Physics. [S0003-6951(99)02232-9]

Extremely transparent and conductive ZnO:Al thin films prepared by photo-assisted metalorganic chemical vapor deposition (photo-MOCVD) using AlCl3(6H(2)O) as new doping material
No full textExtremely transparent and conductive ZnO:Al thin films were successfully prepared by a photo-assisted metalorganic chemical vapor deposition (photo-MOCVD) technique at a temperature of 140 degrees C using diethylzine and H2O as source materials. The vapor from an aqueous solution of aluminum chloride hydrate (AlCl3(6H(2)O)) was used as a doping gas. ZnO:Al thin films with a minimum resistivity of 6.22 x 10(-4) Omega cm were obtained. Their total transmittance at 550 nm was 91%. Moreover, the average transmittance in the wavelength region of 400 nm to 1200 nm was over 91%. The new Al-doping method using AlC1(3)(6H(2)O) by the photo-MOCVD, proposed for the first time in this study, is economical as well as safe, and high-quality ZnO:Al can be successfully applied to a transparent conductive electrode for large area thin-film solar cells
Risk of QT prolongation through drug interactions between hydroxychloroquine and concomitant drugs prescribed in real world practice
No full textHydroxychloroquine has recently received attention as a treatment for COVID-19. However, it may prolong the QTc interval. Furthermore, when hydroxychloroquine is administered concomitantly with other drugs, it can exacerbate the risk of QT prolongation. Nevertheless, the risk of QT prolongation due to drug-drug interactions (DDIs) between hydroxychloroquine and concomitant medications has not yet been identified. To evaluate the risk of QT prolongation due to DDIs between hydroxychloroquine and 118 concurrent drugs frequently used in real-world practice, we analyzed the electrocardiogram results obtained for 447,632 patients and their relevant electronic health records in a tertiary teaching hospital in Korea from 1996 to 2018. We repeated the case–control analysis for each drug. In each analysis, we performed multiple logistic regression and calculated the odds ratio (OR) for each target drug, hydroxychloroquine, and the interaction terms between those two drugs. The DDIs were observed in 12 drugs (trimebutine, tacrolimus, tramadol, rosuvastatin, cyclosporin, sulfasalazine, rofecoxib, diltiazem, piperacillin/tazobactam, isoniazid, clarithromycin, and furosemide), all with a p value of < 0.05 (OR 1.70–17.85). In conclusion, we found 12 drugs that showed DDIs with hydroxychloroquine in the direction of increasing QT prolongation
New nanoporous carbon materials with high adsorption capacity and rapid adsorption kinetics for removing humic acids
No full textWe report that new nanoporous carbon materials (SMCI), which were produced using silica sol particles as templates, show higher and faster adsorption of humic acids than two commercial activated carbons (F400 and Norit SA). In the best result, SMCI showed 16 times the adsorption capacity of conventional activated carbons. In addition, the adsorption of humic:acids on SMCI proceeded very quickly, reaching the equilibrium concentration of humic acids within 15 min. (C) 2002 Elsevier Science Inc.

Decision rights, residual claim and performance: A theory of how the Chinese state enterprise reform works
No full textThis paper is intended to model the process of shifting decision rights and residual claim from the central agent (government) to the inside members of the firm in China, and to analyze how the reform has improved performance of the state-owned enterprises. We show that the bargaining solution between the central agent and the firm is preferred to a one-sided solution, and that managerial discretion of state enterprises can greatly improve efficiency through both its direct incentive effect and indirectly hardening budget constraints. Further improvement of efficiency requires that authority of selecting management is transferred from bureaucrats to capitalists, which implies privatization of the state enterprises. China is already well on its way.EconomicsSSCI10ARTICLE167-82
