Hui Sun, Hsuan-Chung Wu, Sheng-Chi Chen, Che-Wei Ma Lee, Xin Wang
Amorphous Si (a-Si) films with metal silicide are expected to enhance the absorption ability of pure a-Si films. In this present study, NiSi (20 nm)/Si (40 nm) and AlSi (20 nm)/Si (40 nm) bilayer thin films are deposited through radio frequency (RF) sputtering at room temperature. The influence of the film's composition and the annealing temperature on the film's optical absorption is investigated. The results show that all the NiSi/Si films and AlSi/Si films possess higher absorption ability compared to a pure a-Si film (60 nm)...

BACKGROUND: Taxanes are drugs used in various chemotherapeutical protocols to treat solid tumors. They have multiple systemic adverse effects, such as bone marrow suppression, alopecia, nausea, and vomiting, and may rarely cause ocular symptoms. In the past decade, a few reported cases have shown the occurrence of a cystoid macular edema with significant visual loss after the use of a taxane-based chemotherapy. The aim of this study was to compare the central macular thickness (CMT) before and after the initiation of a taxane-based therapy in visually asymptomatic patients and to elucidate the possible impact of these drugs on the vision of cancer patients...

Microbial fuel cell-coupled constructed wetlands (CW-MFCs) use electrochemical, biological, and ecological functions to treat wastewater. However, few studies have investigated the risks of antibiotic resistance genes (ARGs) when using such systems to remove antibiotics. Therefore, three CW-MFCs were designed to assess the dynamics of ARGs in filler biofilm and effluent over 5000 h of operation. The experimental results indicated that relatively high steady voltages of 605.8 mV, 613.7 mV, and 541.4 mV were obtained at total influent antibiotic concentrations of 400, 1,000, and 1600 μg L(-1), respectively...
