Hard-Wired Dopant Networks and the Prediction of High Transition Temperatures in Ceramic Superconductors by J. C. Phillips

“…Popular “first principle” methods for predicting transition temperatures in conventional crystalline superconductors have failed for cuprate HTSC, as have parameterized models based on CuO2 planes (with or without apical oxygen). Following a path suggested by Bayesian probability, it was found that the glassy, self-organized dopant network percolative model is so successful that it defines a new homology class appropriate to ceramic superconductors. …”

Effect of ADH II Deficiency on the Intracellular Redox Homeostasis in Zymomonas mobilis by Nina Galinina, Zane Lasa, Inese Strazdina, Reinis Rutkis, Uldis Kalnenieks

“…Mutant strain of the facultatively anaerobic, ethanol-producing bacterium Zymomonas mobilis, deficient in the Fe-containing alcohol dehydrogenase isoenzyme (ADH II), showed impaired homeostasis of the intracellular NAD(P)H during transition from anaerobic to aerobic conditions, and also in steady-state continuous cultures at various oxygen supplies. At the same time, ADH II deficiency in aerobically grown cells was accompanied by a threefold increase of catalase activity and by about 50% increase of hydrogen peroxide excretion. …”

A Novel Drug-Drug Salt of Naproxen and Vortioxetine: Synthesis, Characterization, and Solubility Study by Xianrui Zhang, Yuting Gao

“…The NAP and VOT molecules in the salt were connected by N-H+⋯O hydrogen bonds between the carbonyl oxygen of NAP and the piperazine group of VOT. In addition, solubility and dissolution rate experiments were performed in water and pH 6.86 phosphate buffers, and the result suggested that salt formation could increase the solubility and dissolution rate of NAP and VOT in water. …”

Steel Pipe Internal Corrosion Protection Using Magnesium Anode: Impact of Protective Potential and Phase Layer Formation on Corrosion Rate by Georgii Vasyliev, Yuriy Gerasymenko

“…However, for the remaining part of the metal pipe, the reduction of corrosion rate of 1.5 times was obtained due to the formation of the phase layer on the metal surface that leads to the reduction of oxygen supply. The results obtained in the study can be further applied for designing and maintenance of water supply systems.…”

Characteristics of Generating Carbon Oxides at Low-temperature Oxidation Stages of Low-Rank Coal by Yimeng Song

“…The research results indicate that the low-temperature oxidation phase of coal is divided into four main phases, namely, the physical-chemical adsorption phase, the desorption phase, the dynamic equilibrium phase, and the oxidative adsorption phase, each of which has different characteristics for the production of carbon-oxygen compounds, which is important for the prediction of coal spontaneous combustion and the prevention of coal geological disasters.…”

A mutation in RNA polymerase imparts resistance to β-lactams by preventing dysregulation of amino acid and nucleotide metabolism by Yesha Patel, John D. Helmann

“…These same pathways are upregulated by CEF, and their derepression increases CEF sensitivity and antibiotic-induced production of reactive oxygen species. The CEF-resistant rpoC G1122D mutant evades these metabolic perturbations, and repression of the BCAA and pyrimidine pathways may function to restrict membrane biogenesis, which is beneficial when cell wall synthesis is impaired. …”
