A novel photocatalysis and gas sensing material was synthesized by decorating Au nanoparticles on tungsten trioxide nanorods. Tungsten nanorods were prepared through the ion-exchange method combined with hydrothermal treatment further modified (Au NPs). After NPs decorated surface of WO3 (WO3 NRs), reducing (hydrogen, methanol, ethanol, etc.) properties photocatalytic performance rhodamine B (RhB) all greatly improved. NP NP@WO3 NRs) exhibit not only larger response (H2 50 ppm, recovery time...
Abstract On the development of flexible electronics, a highly nonvolatile memory, which is an important circuit component for portability, necessary. However, flexibility existing memory has been limited, e.g . smallest radius into can be bent millimeters range, due to difficulty in maintaining properties while bending. Here we propose ultra resistive using Ag-decorated cellulose nanofiber paper (CNP). The CNP devices showed stable effects with 6 orders ON/OFF resistance ratio and small...

Seeking a novel approach magnify their sensitivities toward gas molecules, e.g., volatile organic compounds (VOCs), will definitely expand applications in the frontier area of healthcare air-quality monitoring. In this work, delafossite CuCrO2 (CCO) nanoparticles different grain sizes have been utilized oxide sensors. It was found that singly...
Background Biocatalytic processes often require a full recycling of biocatalysts to optimize economic benefits and minimize waste disposal. Immobilization onto particulate carriers has been widely explored as an option meet these requirements. However, surface properties affect the amount immobilized, their bioactivity stability, hampering wide applications. The aim this work is explore how immobilization lipases magnetite nanoparticles affects biocatalytic performance under carefully...
Nitrogen dioxide (NO2) is one of the air pollutant gases that harms environment, human health, and world ecosystem. The main source NO2 emission combustion engine, therefore, it requires a gas-sensing device to monitor emission.
