ABSTRACTThe interaction of nitrogen trifluoride (NF3) with silicon (Si) surfaces has been investigated by x-ray photoelectron spectroscopy (XPS). Si (100) surfaces were subjected to plasmas created by NF3 gas mixtures and ion bombardment from NF3-generated ion beams as a means of approximating the ion component of plasma processing under controlled conditions. NF 3 plasma processing has lead to the appearance of an interesting high binding energy component in F 1s XPS spectra. Investigation into the mechanism responsible for the high binding energy component suggests that the unusual component is directly influenced by diluent gas ions in the gas mixtures. It is postulated that the high binding energy component is the result of neutral fluorine incorporated in the Si lattice as a result of an ion damage mechanism.

A 3D electrocatalyst designed by ginkgo-nut derived porous carbon with CoS2 nanoparticles decoration exhibits a high Li–S battery performance. This is ascribed to a high binding energy towards LiPSs and a low Li+ diffusion energy barrier of CoS2.

AbstractSingle-layer FeSe films grown on the SrTiO3 substrate (FeSe/STO) have attracted much attention because of their possible record-high superconducting critical temperature (Tc) and distinct electronic structures. However, it has been under debate on how high its Tc can really reach due to the inconsistency of the results from different measurements. Here we report spectroscopic evidence of superconductivity pairing at 83 K in single-layer FeSe/STO films. By preparing high-quality single-layer FeSe/STO films, we observe strong superconductivity-induced Bogoliubov back-bending bands that extend to rather high binding energy ~ 100 meV by high-resolution angle-resolved photoemission measurements. They provide a new definitive benchmark of superconductivity pairing that is directly observed up to 83 K. Moreover, we find that the pairing state can be further divided into two temperature regions. These results indicate that either Tc as high as 83 K is achievable, or there is a pseudogap formation from superconductivity fluctuation in single-layer FeSe/STO films.

In the present work, we have employed a molecular docking approach to study the ability of mitocurcumin (MC), a triphenyl phosphonium conjugated curcumin derivative, to inhibit SARS-CoV-2 infection. Computational analysis revealed that MC can bind strongly to SARS-CoV-2 ADP Ribose Phosphatase (NSP3) with high binding energy of -10.3 kcal/mol and to SARS-CoV-2 methyltransferase (NSP10-NSP16 complex) with a high binding energy of -10.4 kcal/mol. We found that MC interacts with critical residues of viral NSP3 macro-domain, known to suppress host immune response, through hydrophobic interactions and occupies its active site. Furthermore, MC interacts with the critical residues of NSP10-NSP16 complex, known to prevent innate immune detection of viral mRNA, through hydrophobic and hydrogen bond interaction and occupies the methyl group donor site. MC is also found to bind to main protease of SARS-CoV-2 and may potentially act as an inhibitor of the viral protease. In conclusion, MC can potentially inhibit the activity of multiple SARS-CoV-2 proteins and may accentuate the innate immune system mediated clearance of viral load resulting in improved clinic outcome in COVID-19 patients.

Doped boron atoms are bridged to glue more electroactive nitrogen sites on the carbon surface, and the high binding energy of the consequent B–C bonds further consolidates the porous carbon scaffold for durable ion/electron transfer.

<p class="AMSmaintext"><span lang="EN-GB">The formation of the Guinier-Preston zones in aluminium alloys is closely linked with the excess vacancies. Traces of tin added to an Al-Ag alloy exert an influence on the Guinier-Preston zones precipitation. Due to their high binding energy with vacancies, tin atoms trap some of these available to promote the diffusion of silver atoms for the formation of the Guinier-Preston zones. At 125°C, tin microalloying slows down the reaction of the Guinier-Preston zones precipitation. The diffusion coefficient of the solute atoms in the Sn free alloy and in the Sn added alloy are determined during the coarsening regime which obeys to the Lifshitz, Slyosov and Wagner theory.</span></p>
