CO2 hydrogenation to methanol and steam reforming (MSR) are regarded as two critical reactions for transportation on-site production of hydrogen, but it still lacks efficient catalysts both reactions. Herein, the CuZnSi-ammonia evaporation method (AEM) catalyst prepared by AEM with extremely low metal loading highly dispersed Cu/Zn species, in particular, high concentration Cu+ exhibits an opti...

We report the synthesis and characterization, reaction kinetics, deactivation mechanism of a series catalysts with metallic nickel (Ni) molybdenum carbide (Mo2C) particles supported on zeolite Y (Ni-Mo2C/FAU) in methane steam reforming (MSR) at 850 °C. Despite low Ni loading 2.4 wt%, MSR Ni-Mo2C/FAU exhibits high activity stability, yet Ni-FAU is significant. Further investigations elucidate th...

On Cu/ZrO2 catalysts, variation of the Cu loading from 0.2 wt% to 80 allows assessing influence Cu-ZrO2 interface on methanol steam reforming (MSR) performance by steering particle size and morphology, revealing contribution potential active sites at intrinsic relative contributions support surface fraction. As ZrO2 influences both CO2-selective selectivity-spoiling MSR reaction channels, disen...

The effect of mechanical activation on the kinetics of ammoniacal thiosulfate leaching of a refractory oxide gold ore containing 2.8 ppm Au was investigated. The gold extraction of 99.81% was achieved by 16 h leaching of a sample mechanically activated for 60 minutes. The gold extraction observed for a similar reference sample without mechanical activation was only 55%. Studies revealed that le...

The interest in mechanochemical reactions and their fields of application have increased enormously recent times. Mechanically activated offer the advantage cost-efficiency as well environmentally friendly syntheses routes. In contrast to thermally induced processes, energy transfer via milling media takes place on a local scale. This leads unique reaction pathways, which often also result form...

Traditionally chemical reactions are driven by light, thermal, chemical, or electrical potential. Mechanically induced bond cleavage can also be achieved, but is typically non-selective and/ or destructive. [ 1 ] By synthesizing and linking force-sensitive molecules (mechanophores) into a polymer backbone, mechanical deformation can be used to drive site-specifi c in situ chemical reactions. A ...

The goal of biclustering in a gene expression data matrix is to find a submatrix such that the genes in the submatrix show highly correlated activities across all conditions in the submatrix. A measure called Mean Squared Residue (MSR) is used to simultaneously evaluate the coherence of rows and columns within a submatrix. In this paper a new method for biclustering gene expression data is deve...

The MSR field has received a great deal of attention and has now its own research conference : http://www.msrconf.org/. However performing MSR studies is still a technical challenge. Indeed, data sources (such as version control system or bug tracking systems) are highly heterogeneous. Moreover performing a study on a lot of data sources is very expensive in terms of execution time. Surprisingl...

Self-touch is considered important for bodily self-consciousness and self-other distinction has been reported to improve clinical symptoms of disembodiment. To investigate the link between self-touch disembodiment in healthy participants, we studied effect versus touch produced by another person (other-touch) on experimentally induced In a mixed reality paradigm, across two experiments, partici...
