This research explored a novel chemical reduction of organic aluminum for plating Al on a graphene surface. The thermodynamics of the Al plating reaction process were studied. The Al plating process consisted of two stages: the first was to prepare (C₂H₅)₃Al. In this reaction, the ΔH(enthalpy) was 10.64 kcal/mol, the ΔG(Gibbs free energy) was 19.87 kcal/mol and the ΔS(entropy) was 30.9 cal/(mol·K); this was an endothermic reaction. In the second stage, the (C₂H₅)₃Al decomposed into Al atoms, which were gradually deposited on the surface of the graphene and the Al plating formed. At 298.15 K, the ΔH was -20.21 kcal/mol, the ΔG was -54.822 kcal/mol, the ΔS was 116.08 cal/(mol·K) and the enthalpy change was negative, thus indicating an endothermic reaction.

In the process of zinc hydrometallurgy, the content of fluorine in zinc sulfate solution directly affects the stripping of the zinc plate, which easily leads to the deterioration of working conditions. It not only has a serious impact on the entire zinc hydrometallurgical system but also causes huge economic losses. Especially in the process of zinc secondary resource utilization, the concentration of fluoride ions in the electrolyte exceeds the control standard of smelting enterprises, which has become a long-term technical challenge in the smelting industry.

The black soldier fly, , is a voracious scavenger of various organic materials; therefore, it could be exploited as a biological system for processing daily food waste. In order to survey novel hydrolytic enzymes, we constructed a fosmid metagenome library using unculturable intestinal microorganisms from . Through functional screening of the library on carboxymethyl cellulose plates, we identified a fosmid clone, the product of which displayed hydrolytic activity.

Background: Temperature increases in the context of climate change affect numerous mental health outcomes. One such relevant outcome is involuntary admissions as these often relate to severe (life)threatening psychiatric conditions. Due to a shortage of studies into this topic, relationships between mean ambient temperature and involuntary admissions have remained largely elusive.

Calcium metal batteries with high capacity and low cost are promising alternatives to Li-ion batteries for large-scale energy storage. However, its development is crucially impeded by the irreversible Ca metal anode, which is highly associated with uncontrollable Ca plating/stripping. Here, we report a new riveting strategy to regulate the nucleation and growth of a Ca metal anode in the 3D structure of a carbon nanotube film (CNF) by introducing in situ-formed Na metal mediators.

Introduction And Objective: The aim of the study was to investigate the effect of bee venom on the activity of two analgesics: ketoprofen (a non-steroidal anti-inflammatory drug) and tramadol (an opioid drug) in the acute thermal pain model (hot-plate test) in mice.
Material And Methods: Linear regression analysis was used to evaluate the dose-response relationship between logarithms of drug doses and their resultant maximum possible anti-nociceptive effects in the mouse hot-plate test. Doses that increased the anti-nociceptive effect by 20% (ED values) for bee venom, ketoprofen and tramadol, and their combination were calculated from linear equations.
