We report on the preparation of capacitive-type relative humidity sensors incorporating plasma-activated multi-wall carbon nanotube (p-MWCNT) electrodes and their performance compared with existing commercial technology. Highly open porous conductive electrodes, which are almost impossible to obtain conventional metal fabricated by spray-depositing MWCNT networks a polyimide layer. Oxygen plasma activation MWCNTs is also explored improve water adsorption films, introducing oxygen-containing...
Summary Statins are potent inhibitors of hydroxyl-3-methylglutaryl co-enzyme A (HMG-CoA) reductase, and have emerged as potential anti-cancer agents based on preclinical evidence. In particular, compelling evidence suggests that statins a wide range immunomodulatory properties. However, little is known about the role in tumour immune tolerance. Tumour tolerance involves production immunosuppressive molecules, such interleukin (IL)-10, transforming growth factor (TGF)-β...

Silicon heterojunction solar cells require high quality surface passivation to enhance the device performance. In this study, dual-layered hydrogenated amorphous silicon (a-Si:H) deposited at different hydrogen dilution is investigated for improvement of passivation. Dual-layered a-Si:H functionalized as smooth interfacial and dense capping layers. As-deposited shows 33.4% enhancement minority carrier lifetime from quasi-steady-state photo-conductance measurements up 197.6 μs comparing 148.1...
Two-dimensional (2D) transition metal dichalcogenides (TMDs) have attracted significant attention for their outstanding optoelectrical properties. Unlike most TMDs with layer-dependent photoresponsivity, rhenium disulfide (ReS2) shows excellent thickness-independent photoresponsivity. Herein, we show a surfactant-free polyvinyl alcohol (PVA)-assisted exfoliation method 2D-TMDs in aqueous solution and transparent photosensitive memristor synapse device based on ReS2 nanosheets composited PVA....
A new concept of a tunneling oxide-free nonvolatile memory device with deep trap interface floating gate is proposed. This demonstrates high on/off current ratio 107 and sizable window due to traps at the between channel dielectric layers. Interestingly, irradiation 400 nm light can completely restore program state initial one (performing an erasing process), which attributed visible light-sensitive layer. Device reproducibility enhanced by selectively passivating shallow using in situ H2...
Abstract Herein, In x Ti y O films are successfully deposited via the atomic layer deposition method, which involves sub‐cycles of 2 3 and TiO application at a growth temperature 200 °C. an excellent alternative to for use in channels thin film transistors (TFTs), can be used avoid issues such as metal‐like conduction characteristics undesirable negative shifts. Adjusting addition enables modulation cut‐off wavelength UV region. However, adversely affects on‐current level. The content is...
This work reports an innovative method for achieving high quality MoS<sub>2</sub> and MoSe<sub>2</sub> films uniformly on large-area wafers at growth temperatures of 600 °C or lower.
Abstract The development of electronic devices that emulate the learning mechanism human brain is crucial for replicating capabilities brain. Photoelectric with are good candidates input‐energy‐effective and multi‐level memory devices. Herein, a novel TiO 2 ‐metaloxide‐semiconductor field‐effect transistor (MOSFET)‐based device reported, effectively converts learned data to long‐term (LTM) by longer stimulus intervals realizes multi‐state memory. This programmed UV light uses deep trap sites...

Two-dimensional MoX2 (X = S, Se) films were vertically grown on highly rough transparent conducting F-doped SnO2 glass substrates for the first time and successfully used as photogenerated carrier-guiding layers (CGLs) in hydrogenated amorphous silicon (a-Si:H) thin film solar cells (TFSCs). The MoSe2 CGL could be at 530 °C using thermally cracked small Se-molecules FTO significantly improved cell performance.
