Superconductivity in ordered Li-Al-B compounds.

Using first principles calculations, we show that [Formula: see text] materials have strong electron-phonon coupling, with many having a superconducting critical temperature ([Formula: see text]) that exceeds that of the more familiar [Formula: see text] at ambient pressure. In particular, we find that [Formula: see text] is the most stable member of the family, with [Formula: see text] whilst the peak [Formula: see text] is with [Formula: see text] which has [Formula: see text]. Our results reveal that these materials are both thermodynamically and dynamically stable, with strong electron-phonon coupling, indicating significant potential for practical superconducting applications.

Evaluating the safety and effectiveness of the sub-400 corneal cross-linking protocol: initial clinical and morphological findings.

Purpose: To assess the safety and the efficacy of the "Sub-400 corneal cross-linking (CXL) protocol" for progressive keratoconus (KC) in ultrathin corneas.

Methods: The study included thirty four patients with progressive KC, who underwent CXL using the "Sub-400" protocol due to intraoperative thinnest corneal pachymetry ranging from 295 to 398 μm after epithelial removal. After the epithelium was removed, the following ultraviolet A irradiation was applied at a fluence of 3 mW/cm and the duration was adjusted based on the specific corneal stromal thickness.

Investigation of Wettability, Thermal Stability, and Solar Behavior of Composite Films Based on Thermoplastic Polyurethane and Barium Titanate Nanoparticles.

Herein, composite films were produced by incorporating different amounts (1, 3, 5, and 7%) of barium titanate nanoparticles into the thermoplastic polyurethane matrix using a solution casting method. This study examined the impact of the presence and concentration of a barium titanate additive on morphologic properties, mechanical performance, thermal stability, solar behavior, and wettability of produced film samples. The films were characterized by Fourier transform infrared spectroscopy, differential scanning calorimetry, thermal gravimetric analysis, scanning electron microscope, ultraviolet-visible near-infrared spectrophotometer, water contact angle, and tensile strength measurements.

An Experimental Insight Into the Role of Agomelatine in Renal Ischemia/Reperfusion Injury.

Acute kidney injury (AKI) is one of the leading causes of chronic kidney disease and accounts for 50%-75% of mortality following renal pathologies or organ transplantation. Ischemia‒reperfusion injury (IRI) involves an interrupted blood supply to organs and the kidney; IRI exacerbates AKI development. Owing to several pharmacological treatment methods, AKI still has a poor prognosis, and novel therapeutic options are needed.
