1 mM glucose (positive control) (p < 0.01), indicating that the loss of aioR or mcp did not interrupt the bacte- rial chemotactic system for certain carbon sources (Fig. 2). Chemotaxis experiments showed positive responses towards As(III) (0.5 mM up to 2 mM, data ...
Activated carbonZero-valent ironCatalytic wet peroxide oxidationThe main objective of the work is to prepare catalysts based on nanoscale zero-valent iron supported on activated carbon (nZVI/AC) and to test their activity for catalytic wet peroxide oxidation of phenol. The catalysts were characterized...
Thus, it is of great interest to develop efficient and low-cost catalysts for the low-temperature operation of the CO oxidation reaction. Metal-free catalysts have attracted attention due to their high activities in the catalytic oxidation reaction. Various kinds of carbon-based materials, such as...
The renewability and sustainability issues of producing chemicals, materials and fuels from depleted fossil resources have greatly accelerated and expanded the development of renewable energies and resources [[1], [2], [3]]. As a highly-accessible and renewable natural carbon source, biomass is curr...
However, the Be/Sn co-doping sequence accumulated the highest lattice strain and micro-strain, most probable because Be will first occupy the most preferable and large sites, resulting in larger number of under-coordinated O atoms, and also leaving smaller or unsuitable doping sites for Sn in ...
In the case of ZnHCCO, the peaks can be assigned at 2177, 1605, 698 and 450 cm−1 for strong C≡Nstretching frequency; O–H bending of interstitial water molecules; metal-carbon bending; and metal-cyanide bending, respectively. The peak assignment for the rest of the MHCCo complexes ...

Nitrogen Dioxide This free radical (NO2•) can be formed from the autoxidation of nitric oxide, from the decay of peroxynitrite in the presence of carbon dioxide and from the oxidation of nitrite. It is an oxidizing species with E◦'(NO2•/NO2–) = +1.04 V [88]. The reaction ...
It was concluded that the presence of Ag+ sites on the catalyst is responsible for the high soot oxidation activity. Keywords: silver oxide; cerium oxide; oxidation; diesel soot; catalysis; ALD 1. Introduction The number of diesel-powered vehicles has increased rapidly in recent years due to ...
POSS is an inorganic-organic hybrid compound with a general formula (RSiO1.5)n, where R is an organic group, n is the number of silicon atoms (n = 8, 10, 12), and a special molecular structure which is composed of an inorganic core cage and the functional organic group surrounding ...
