Influence of Al2O3 reinforcement on precipitation kinetic of Cu-Cr nanocomposite
(Elsevier, 2011)
In this paper, the kinetic of precipitation process in mechanically alloyed Cu-1 wt.% Cr and Cu-1 wt.% Cr/3 wt.% Al2O3 solid solution was compared using differential scanning calorimetry (DSC), X-ray diffraction (XRD) and ...

Monolayer arrangement of fatty hydroxystearic acids on graphite: Influence of hydroxyl groups
(Elsevier, 2013)
Previous studies have indicated that long-chain linear carboxylic acids form commensurate packed crystalline monolayers on graphite even at temperatures above their melting point. This study examines the effect on the ...

Theoretical studies on the mechanism of molybdenum-catalysed deoxydehydration of diols
(Royal Society of Chemistry, 2023-03-18)
Molybdenum-catalysed deoxydehydration (DODH) of vicinal diols to alkenes has been investigated using density functional theory (DFT). In particular, the mechanism of DODH of diols using a phosphane as a reductant and a ...

Current scenario and prospects in manufacture strategies for glass, quartz, polymers and metallic microreactors: A comprehensive review
(Institute of Chemical Engineers, 2021)
One of the most remarkable benefits of the microreactors is the achievement of more efficient processes by enhancing the heat and mass transfer phenomena, which is the key factor for processes intensification in chemical ...

Does shaping catalysts modify active phase sites? A comprehensive in situ FTIR spectroscopic study on the performance of a model Ru/Al2O3 catalyst for the CO methanation
(Elsevier, 2018)
Routinely, it seems assumed that the catalytic layer coated on monoliths and microchannel reactors preserve the properties of the initial powder catalyst. However, this assumption should be reasonably demonstrated since ...

Effect of starch as binder in carbon aerogel and carbon xerogel preparation
(Elsevier, 2019)
Carbon aerogels and carbon xerogels were synthesized through resorcinol – formaldehyde polycondensation using Na2CO3 as catalyst. The effect of soluble starch introduction in the organic gel preparation on the porous surface ...

Large-scale preparation and labelling reactions of deuterated silanes
(John Wiley & Sons, 2012)
A catalytic synthesis of deuterated silanes SiEt3D, SiMe2PhD and SiPh2D2 is reported that allows their facile generation in a 3–4 g scale, utilizing D2 (0.5 bar) as the hydrogen isotope source and low catalyst loadings ...

Cooperative activation of X–H (X = H, C, O, N) bonds by a Pt(0)/Ag(i) metal-only Lewis pair
(Royal Society of Chemistry, 2019)
Metal-only Lewis pairs made of Pt(0)/Ag(I) combinations have been previously reported, but their cooperative reactivity remains unexplored. Here we demonstrate that these systems are capable of synergistically activating ...

Influence of gold particle size in Au/C catalysts for base-free oxidation of glucose
(Elsevier, 2017)
A series of gold colloids were prepared and immobilized on commercial activated carbon. The influence of the colloid preparation and stability were studied and related to the gold particle size in the final catalyst. The ...
