Fabrication of core−shell structure of M@C (M=Se, Au, Ag2Se) and transformation to yolk−shell structure by electron beam irradiation or vacuum annealing
Selenium @ carbon core−shell spheres have been synthesized via a simple one-step hydrothermal carbonization process using sucrose and sodium selenite as precursors. Metal selenide or noble metal, e.g. Ag2Se or Au, can be ...
A carbon monoxide gas sensor using oxygen plasma modified carbon nanotubes
Carbon monoxide (CO) is a highly toxic gas that can be commonly found in many places. However, it is not easily detected by human olfaction due to its colorless and odorless nature. Therefore, highly sensitive sensors need ...
An effective method for the fabrication of few-layer-thick inorganic nanosheets
Intercalation and exfoliation of lithium: Few-layer-thick inorganic nanosheets (BN, NbSe2, WSe2, Sb2Se3, and Bi2Te3) have been prepared from their layered bulk precursors by using a controllable electrochemical lithium ...
