Synthesis and Unique Behaviors of High-Purity HEA Nanoparticles Using Femtosecond Laser Ablation.

High-entropy alloys (HEAs) are a class of metal alloys consisting of four or more molar equal or near-equal elements. HEA nanomaterials have garnered significant interest due to their wide range of applications, such as electrocatalysis, welding, and brazing. Their unique multi-principle high-entropy effect allows for the tailoring of the alloy composition to facilitate specific electrochemical reactions.

Cholecystectomy via Kocher incision without peritoneal closure.

This investigation was carried out to evaluate the surgical wound outcome of patients who underwent cholecystectomy via Kocher incision, without peritoneal closure. Consecutive patients (n = 129) were randomized either to have the peritoneal closure (n = 66) or to have this step omitted (n = 63). Demographic data of the patients were similar in both groups.

Monitoring for clenbuterol abuse in N. Ireland 1989-1994.

Laboratory testing in N. Ireland for the illegal growth promoting agent, clenbuterol (CBL), is centralized at the Veterinary Sciences Division, Belfast. During the past 6 years a variety of testing schemes have evolved to determine the level of abuse of this drug in the local meat industry.
