The reversible covalent binding of diols to an -Bn 1,2-BN cyclohexane has been studied by B and H NMR spectroscopy and single-crystal X-ray diffraction analysis. The activation barrier for the reversible B-N Lewis acid-base interaction has been measured by variable-temperature NMR with bound (2,3)-(-)-2,3-butanediol ( = -40 °C, Δ = 11.2 ± 0.2 kcal mol). Deuterium labeling experiments demonstrate that ligand exchange is reversible and rapid at room temperature, and competitive binding studies establish diol association as a thermodynamically controlled process.

Background: We aimed to evaluate and compare the rise in the temperature for the safety of the kidney parenchyma on firing the Holmium: Yttrium Aluminium Garnet laser and the Thulium Fiber Laser during laser lithotripsy in humans.
Method: We included 30 pre-stented patients with renal calculi undergoing Retrograde intra-renal surgery. They were randomized into two groups - 15 patients underwent holmium laser lithotripsy and 15 patients underwent TFL laser lithotripsy.

With the global surge in lithium-ion batteries (LIBs), recycling spent LIBs has become an essential and urgent research area. In the context of global efforts to promote sustainable development, and achieve energy conservation and emission reduction, advancing recycling technologies that efficiently recover critical metals like Ni, Co, Mn, and Li is crucial. Herein, a novel and environmentally friendly simplified process for selectively extracting critical metals from the mixed electrode materials of spent LIBs is proposed for the first time.

Sour rot (SR) is a late-season non-Botrytis rot affecting grapevines, resulting from a complex interplay of microorganisms, including non-Saccharomyces yeasts and acetic acid bacteria. Nonmicrobial factors contributing to disease development encompass vectors (e.g.

The remediation of wastewaters contaminated with dyes (discharged mainly from industry) is very important for preserving environmental quality and human health. In this study, a new composite chitosan (CS)-based adsorbent combined with activated carbon (AC) and curcumin (Cur) (abbreviated hereafter as CS/AC@Cur) in three different ratios (12.5%, 25%, and 50%) was synthesized for the removal of anionic [reactive black 5 (RB5)] and cationic [methylene blue (MB)] dyes in single-component or binary systems.

Self-organization realizes various nanostructures to control material properties such as superconducting vortex pinning and thermal conductivity. However, the self-organization of nucleation and growth is constrained by the growth geometric symmetry. To realize highly controlled three-dimensional nanostructures by self-organization, nanostructure formation that breaks the growth geometric symmetry thermodynamically and kinetically, such as tilted or in-plane aligned nanostructures, is a challenging issue.
