Abstract With the description of more and complex one‐ two‐dimensional NMR experiments comes need to develop methods make a comprehensive interpretation various different that can be carried out on same sample or series related samples. We present some examples modelling solid‐state spectra I = ½ spin quadrupolar nuclei, using laboratory‐developed software is made available community. Copyright © 2001 John Wiley & Sons, Ltd.
Due to its three hydroxyl groups, glycerol is a potential starting material for various high value fine chemicals such as dihydroxyacetone, tartronic acid and mesoxalic acid. The corresponding oxidation reactions are catalysed by metals palladium, platinum, bismuth or gold. Nevertheless, the selectivity not only depends on type of active phase, but also influenced numerous parameters metal particles size, pore size support pH reaction medium. This review describes recent developments in...
Catalytic conversion of ethanol is a promising technology for producing sustainable butadiene. This paper reviews the reaction and its catalysts, discusses challenges their development faces.
1,3-Butadiene is traditionally produced as a byproduct of ethylene production from steam crackers. What unusual that the alternative route for this important commodity chemical via ethanol was developed long time ago, before World War II. Currently, there renewed interest in butadiene biomass due to general trend replace oil industry. This review describes recent progress (ETB) by one or two-step process through intermediate acetaldehyde with an emphasis on new catalytic systems. The...
HAP solids were prepared with different Ca/P ratios and Na<sup>+</sup>cations before being characterized by XRD, XPS, LEIS, NMR, IR, TGA. Their acid–base properties then measured discussed in relation to the characterization results.
While the initial catalytic performances of silica-supported silicotungstic acid are high in glycerol dehydration reaction, they rapidly decrease with time on stream and acrolein yield quickly decreases.
The interaction of multiply charged ions (He${}^{2+}$, ${\mathrm{O}}^{3+}$, and Xe${}^{20+}$) with gas-phase pericondensed polycyclic aromatic hydrocarbon (PAH) molecules coronene (C${}_{24}$H${}_{12}$) pyrene (C${}_{16}$H${}_{10}$) is studied for low-velocity collisions ($v\ensuremath{\leqslant}0.6$ a.u.). mass spectrometric analysis shows that singly up to quadruply intact are important reaction products. relative experimental yields compared the results a simple classical over-the-barrier...
Fully characterized HAP solids with various Ca/P ratios were used in the Guerbet reaction of ethanol to produce higher alcohols. In this respect, an optimal ratio between amount acid and basic sites 5 was evidenced.
Abstract Ti 3 C 2 MXenes with different halogen modifications are prepared rapidly and efficiently by microwave molten salt method, the MXene surface functional group modification is successfully achieved to address problems of low purity, complex groups, uncontrollable energy band structure obtained traditional liquid phase etching. Among them, iodine (I) onto changes gap, resulting in easier photoexcitation more photogenerated carriers. The increased Fermi closer conduction band, decreased...
We report highly selective covalent bond modifications in collisions between keV alpha particles and van der Waals clusters of ${\mathrm{C}}_{60}$ fullerenes. Surprisingly, $\mathrm{C}_{119}{}^{+}$ $\mathrm{C}_{118}{}^{+}$ are the dominant molecular fusion products. use dynamics simulations to show that $\mathrm{C}_{59}{}^{+}$ $\mathrm{C}_{58}{}^{+}$ ions---effectively produced prompt knockout processes with ${\mathrm{He}}^{2+}$---react rapidly form dumbbell $\mathrm{C}_{118}{}^{+}$. Ion...
Here an overview of all pathways that integrate chemical and biological catalysis is presented. We emphasize the factors to be considered in order understand catalytic synergy.
Dimethoxymethane or DMM is a versatile chemical with applications in many industries such as paints, perfume, pharmacy, and fuel additives.

Abstract CeNi X H Z O Y nano‐oxyhydride catalysts were developed for the highly efficient sustainable hydrogen production from ethanol and water in oxidative steam reforming reaction. After an situ treatment temperature range of 200–300 °C, cerium–nickel binary mixed oxides became reservoirs, which called oxyhydrides, presence species hydride nature anionic vacancies oxides. A novel technology was room by using chemical energy released reaction between oxygen, completely converted...
