Binding energies determined from kinetic energy release measurements following the evaporation of single molecules from the molecular clusters H +(H 2O) n, H +(NH 3) n and H +(CH 3OH) ndoi:10.1016/j.ijms.2012.08.003High resolution mass spectrometry in conjunction with a supersonic source ...
2a. The binding energies of these intermediates are highly correlated, leading to a minimum theoretical overpotential of about 0.37 V60. In contrast, OCM with the introduction of a second active center can break the structural constraint on the crucial oxygenated intermediate. In this case, the...
of atoms was constructed with the bottom 3 layers of atoms being fixed without optimization to mimic the bulk structure. A vacuum layer with a thickness of 10 Å was constructed to avoid the interactions between the layers. The adsorption energiesEadwere calculated from the following equation:...
Following a 1-week acclimation period, mice were weighed, randomized into 2 groups (5 males and 5 females per group), and shaved. The control group was treated daily with the cream vehicle, while the treatment group was treated daily with 15% WDL cream. The skin condition, food intake, ...
Practical methods to obtain functionally graded adhesives include the following two: mixing adhesives with particles of different properties or in different volumetric percentages to create a non-uniform reinforcement distribution in the bondline; and applying different localised curing cycles. Compared to ...
(TLUD) cookstove, using wood pellets as fuel, is studied. Furthermore, the gasification process was thermodynamically characterized. The TLUD cookstove assessment was carried out following a modified water boiling test (WBT). The highest thermal efficiency of the cookstove was 26.74%. The lowest ...
In the studied adsorbents, oxygen can occur in the following multiforms: carbonyl (CO) and/or carboxyl (–O–CO), aliphatic hydroxyl groups, ethers (C–O–C) and/or aromatic hydroxyl groups, and also adsorbed H2O, epoxy groups and/or SiO2 and silica hydroxyl groups, with the dominance (...
Section 4 reports and discusses the results. Section 5 concludes. 2. Data To examine the impact of COVID-19 on financial stock markets, the following stock indices are chosen: the Nikkei 225 (Japan) and SSE (China) to represent Aisa, the SP500 to represent the US; CAC40 (France), ...
No claim is made about the order of the subsequent reactions. The pseudo-first-order rate constants (k1) for this reaction can be estimated by the following Eq. (6): $$\ln \frac{{I_{\mathrm{{n}}}{{I_{\mathrm{{s}}} = - k_1\frac{{P_{\mathrm{{e}}}{\Delta} t}}{{k_{...
The higher bond dissociation energies of β-O-4 linkage with γ-OH (69.2 kcal/mol)25 compared with β-O-4 without γ-OH (65.5 kcal/mol)26 leads to a variety of unwanted by-products, which is the main reason of lower yield. Moreover, the target molecule application is so ...
