The Microstructures, Mechanical Properties, and Energetic Characteristics of a Novel Dual-Phase TiZrWMo High-Entropy Alloy.

High-energy structural materials (ESMs) integrate a high energy density with rapid energy release, offering promising applications in advanced technologies. In this study, a novel dual-phase TiZrWMo high-entropy alloy (HEA) was synthesized and evaluated as a potential ESM. The alloy exhibited a body-centered cubic (BCC) matrix with Mo-W-rich BCC precipitates of varying sizes, which increased proportionally with the W content.

Unveiling the Stacking Fault-Driven Phase Transition Delaying Cryogenic Fracture in Fe-Co-Cr-Ni-Mo-C-Based Medium-Entropy Alloy.

In this work, the tensile deformation mechanisms of the FeCoCrNiMoC-based medium-entropy alloy at room temperature (R.T.), 77 K, and 4.

Effect of Aging Treatment on the Microstructure and Properties of 2.2 GPa Tungsten-Containing Maraging Steel.

Maraging steel is a prominent category of ultrahigh-strength steel (UHSS) characterized by excellent comprehensive properties, and it finds wide applications in manufacturing load-bearing structural components. In this study, a novel tungsten-containing maraging steel, C-250W, was designed. The effects of aging treatments on the mechanical properties, microstructure, precipitations, and reverted austenite of C-250W steel were investigated.

Design, synthesis and mechanism study of novel natural-derived isoquinoline derivatives as antifungal agents.

In screening for natural fungicidal leads, two series of novel 3-aryl-isoquinoline derivatives 8 and 9 were designed and synthesized based on sanguinarine, chelerythrine and berberine. Their structures were confirmed by 1D, 2D NMR and HRMS. Most of the title compounds showed medium to excellent antifungal activity in vitro at 50 mg/L, which were much more active than the lead of sanguinarine.

[Familial male-limited precocious puberty due to Asp578His mutations in the LHCGR gene: clinical characteristics and gene analysis in an infant].

The aim of the study was to provide a descriptive analysis of familial male-limited precocious puberty (FMPP), which is a rare inherited disease caused by heterozygous constitutively activating mutations of the luteinizing hormone/choriogonadotropin receptor gene (LHCGR). The patient was a ten-month-old boy, presenting with penile enlargement, pubic hair formation, and spontaneous erections. Based on the clinical manifestations and laboratory data, including sexual characteristics, serum testosterone levels, GnRH stimulation test, and bone age, this boy was diagnosed with peripheral precocious puberty.

[Analyzing crude/processed root of Polygonum multiflorum from different habitats by UPLC fingerprint and mode identification methods].

To establish a content determination method for 2,3,5,4'-tetrahydroxy stilbene-2-O-β-D-glucoside (TSG) of the crude/processed root of Polygonum multiflorum from different habitats in China and set up the fingerprint by using UPLC. Various samples were pretreated by macro-porous resin. Then UPLC analysis was performed on Waters ACQUITY UPLC@BEH C18 chromatographic column (2.
