In the present contribution,we demonstrate that the sluggish kinetics of oxygen evolution reaction(OER)over the bismuth sulfide(Bi_(2)S_(3))photoanode,which severely restricts its photoelectrochemical activity,is markedly accelerated by employing a sulfatecontaining ***-principle calculation points to the spontaneous adsorption of sulfate(SO_(4)^(2−))on Bi_(2)S_(3)and its capacity of stabilizing the OER intermediates through hydrogen bonding,which is further reinforced by increasing the local density of states near the Fermi level of Bi_(2)S_(3).Meanwhile,the electron transfer is also promoted to synergistically render the ratedetermining step(from O*to OOH*)of OER over Bi_(2)S_(3)kinetically *** but not least,benefitting from such enhanced OER activity and efficient charge separation resulted from depositing Bi_(2)S_(3)on the zinc oxide nanorods(ZnO NRs),forming a core–shell heterojunction,its photocurrent density achieves 8.61 mA·cm^(−2)at 1.23 VRHE,far surpassing those reported for additional Bi_(2)S_(3)-based and several state-of-the-art photoanodes in the literature and further exceeding their theoretical *** great promise of the Bi_(2)S_(3)/ZnO NRs is in view of such outperformance,the superior Faradaic yield of oxygen of more than~80%and the outstanding half-cell applied bias photon-to-current efficiency of~1%well corroborated.

Bank Lending and Economic Growth of Chinese Cities

引用

China & World Economy 2012年第2期20卷 59-79页

作者： Chin hwa lu Chung Hua Shen Department of Finance China University of Technology Department of Finance National Taiwan University

Using a city-level dataset over the period 2004-2006, the present study investigates the relationship between bank lending and the economic growth of Chinese cities. Unlike past studies, we divide bank lending into loans from three types of banks： foreign banks, city banks and other banks. Our findings are threefold. First, the lending of foreign banks exhibits a strong and positive association with the economic growth of Chinese cities. Second, foreign direct investment in the sampled cities enhances the lending effects of foreign banks, but reduces the lending effects of other banks on the economy of Chinese cities. Third, the effects of city competitiveness are similar to those offoreign direct investment; that is, city competitiveness augments the lending effects of foreign banks but reduces the lending effects of other banks.

Photonics Research 2022年第4期10卷 1011-1021页

作者： Dinusha Serandi Gunawardena Xin Cheng Jingxian Cui Geraldi Edbert Linyue lu Yuk Ting Ho hwa-Yaw Tam Department of Electrical Engineering The Hong Kong Polytechnic UniversityKowloonHong KongChina Photonics Research Institute The Hong Kong Polytechnic UniversityKowloonHong KongChina

We report for the first time, to the best of our knowledge, regenerated polymer optical fiber Bragg gratings(RPOFBGs) in ZEONEX-based polymer optical fibers(POFs). The regeneration temperature can be adjusted using a heat treatment process on the POF before FBG inscription, enabling a scalable improvement of the thermal stability of the RPOFBGs. Thermal sustainability of the RPOFBGs at high temperature conditions was investigated for their prolonged use in diverse environments. Furthermore, these RPOFBGs can withstand strain levels up to 2.8% while maintaining a good linearity, even at temperature of 110℃. The RPOFBGs are capable of short-term operation at elevated temperatures of up to 132℃, which is the standard temperature for steam sterilization with at least a 4 min exposure period. The distinction in the morphologies of the two grades of ZEONEX(E48R and 480R, ZEON Corp.) used to fabricate the optical fiber together with the characteristics of UV irradiated and regenerated gratings is explained using micro-Raman spectroscopy. Collectively, these findings provide new heights for long-term operation of POF Bragg gratings(POFBGs) at elevated temperature environments and would be applicable to a wide range of disciplines.

引用

World Journal of Gastroenterology 2005年第7期11卷 1048-1051页

作者： Full-Young Chang Chih-Yen Chen Ching-Liang lu Jiing-Chyuan luo Rei-hwa lu Shou-Dong Lee Division of Gastroenterology

AIM: To investigate the effect of Helicobacter pylori eradication on endothelin-1 (ET-1) and nitric oxide (NO) in duodenal ulcer (DU) patients. METHODS: Sixty-six Hpylori-infected active DU patients were consecutively enrolled to receive one-week triple therapy (rabeprazole, amoxicillin and metronidazole) and then one-month rabeprazole therapy. They were asked back to determine ulcer and Hpylori status using endoscopy one month later. Thirty-seven healthy controls (H pylori +/-:17/20) were enrolled for comparison. Blood samples were collected in each visit to measure plasma ET-1 and nitrate/nitrite levels using an enzyme immunoassay kit. RESULTS: Sixty DU patients finished trial per protocol. The ulcer healing and Hpylori-eradication rates were 86.7% and 83.3%, respectively. Plasma ET-1 level in DU patients was higher than that of Hpylori-negative and positive controls (3.59±0.96 vs0.89±0.54 vs0.3±0.2 pg/mL,PluSION: Both plasma ET-1 and nitrate/nitrite levels increase in active DU patients. After an effective H pylori eradication, DU healing is associated with diminished blood ET-1 level and elevated nitrate/nitrite level.

Impact of Foreign Bank Entry on the Performance of Chinese Banks

引用

China & World Economy 2009年第3期17卷 102-123页

作者： Chung-Hua Shen Chin-hwa lu Meng-Wen Wu Department of Finance National Taiwan University Department of International Business China University of Technology Department of Finance Ming Chuan University

This study investigates how foreign bank/investor penetrations influence local bank performance in China. At the country level, foreign bank penetration is proxied by MacroFP, measured by the percentage of banks with foreign strategic investors （FSI） among total banks. At the bank level foreign bank penetration is proxied by MicroFP, measured by the percentage shareholding of FSl in a bank. When foreign bank penetration is proxied by MacroFP, it is found to improve the profitability of local banks but not to reduce costs. Next, when foreign bank penetration is proxied by MicroFP, it is found to affect neither profitability nor costs. In sum, the present study demonstrates that the opening-up policy is correct from a macro perspective, However, for banks that have introduced FSI, determining the reasons for improvements in performance being inhibited is more important than releasing more shares to foreign investors.

Benzo[1,2-b:4,5-b′]dithiophene(BDT) has been widely used to construct donor-acceptor(D-A) copolymers in organic solar cells(OSCs). However, benzo[1,2-b:4,5-b′]difuran(BDF), an analogue of BDT, has received less attention than BDT. The photovoltaic performance of BDF copolymers has lagged behind that of BDT copolymers. Here, we designed and synthesized two BDF copolymers, PBF1-C and PBF1-C-2Cl. PBF1-C-2Cl, which is composed of BDF and benzo[1,2-c:4,5-c′]dithiophene-4,8-dione connected by a chlorinated thiophene π-bridge, displays a low-lying highest occupied molecular orbital energy level,which helps in yielding a high open-circuit voltage(Voc) in OSCs. As a result, when blended with Y6, PBF1-C-2Cl-based devices showed a high Voc of 0.83 V and a power conversion efficiency(PCE) of 13.10%. To the best of our knowledge, the PCE of 13.10% is among the highest efficiency values for OSCs based on BDF copolymers.
