Influence of the Fuel/Oxidant Ratio on the Elaboration of Binary Oxide Catalyst by a Microwave-Assisted Solution Combustion Method

Three series of binary metal oxide catalysts containing Ni, Cu, or Co oxides were prepared, fully characterized and tested in CO oxidation.The catalysts, with a constant transition metal loading of 10 wt%, were prepared from metal nitrates and urea mixtures by a microwave-assisted solution combustion method.The RV/OV ratio, corresponding to the sto

Division of labor in hand usage is associated with higher hand performance in free-ranging bonnet macaques, Macaca radiate [corrected].

A practical approach to understanding lateral asymmetries in body, brain, and cognition would be to examine the performance advantages/disadvantages associated with the corresponding functions and behavior.In the present study, we examined whether the division of labor in hand usage, marked by the preferential usage of the two hands across manual o

Plant fertilization interacts with life history: variation in stoichiometry and performance in nettle-feeding butterflies.

Variation in food stoichiometry affects individual performance and population dynamics, but it is also likely that species with different life histories should differ in their sensitivity to food stoichiometry.To address this question, we investigated the ability of the three nettle-feeding butterflies (Aglais urticae, Polygonia c-album, and Aglais

Validation of a Holistic System for Operational Analysis and Provision of Ancillary Services in Active Distribution Networks

The advent of distributed renewable energy sources (DRESs) has led to the progressive transformation of traditional distribution networks to active components of the power system.This transformation, however, may jeopardize the reliable grid operation due to the advent of new technical problems, such as network overloading, over-/under-voltage even
