In general, the mixed base metal oxides may be used as catalysts for the oxidation of nitrogen oxide in hot gas streams containing oxygen. They may optionally be used in a combination with palladium or platinum. But platinum, which is very expensive, does not have to be used in such ...
The development of high-performance, portable and miniaturized gas sensors has aroused increasing interest in the fields of environmental monitoring, security, medical diagnosis, and agriculture. Among different detection tools, metal oxide semiconductor (MOS)-based chemiresistive gas sensors are the most ...
base sites are mixed with an organic modifier that contains at least two Lewis base functional groups. Here we demonstrate the strategy by combining cerium oxide and 2-cyanopyridine that self-assembles to form a charge-transfer complex in methanol that exhibits a 2,000-fold increase in reaction...
Metal oxidecatalysts are widely used in the catalytic reaction of oxidation–reduction mechanism; most of the oxides of main group elements are used in the catalytic reaction of acid–base mechanism (such as solid acid catalyst), including oxidation,dehydrogenation, hydrogenation,oxidative dehydrogenation...
[48] used M/Fe catalysts on an Al2O3 base (M = Ni, Mo and Pd) which resulted in a lower deactivation by cracking because the nanoparticles grow away from the catalyst. Oxide supported catalysts can also promote the surface properties and chemisorption of metal particles [43]. As shown ...
metal oxide semiconductors (MOS) are the most commonly exploited sensing materials with advantages like a fast response, low cost, ease of handling, a wide range of target gases, and longer lifetimes. However, they also suffer from disadvantages like higher energy consumption and lower selectivities...

We use an approach that is compatible with complementary metal–oxide–semiconductor (CMOS) processes to stack ten n-channel In2O3 TFTs. Different architectures—including bottom-, top- and dual-gate TFTs—can be fabricated at different layers in the stack. Our dual-gate devices exhibit ...
A gold-free platinum material that is dispersion-strengthened by small, finely dispersed particles of base metal oxide. The base metal is either 0.01-0.5 wt. % Sc or a mixture/alloy of Sc and at least
Since the double metal oxide powder produced by the method of the present invention contains fewer agglomerates, and has the narrow particle size distribution and the polyhedral shape, it can be preferably used as a raw material powder of a metal oxide base ceramic which is used as a functional...
