Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Nb‐Si‐based superalloys are considered as the most potential candidate materials for nickel‐based superalloys due to the lower density and higher using temperature. Here, a type of stable Nbss/γNb5Si3 bi‐phases structure with a coherent interface has been successfully designed. Additionally, the Nbss and γNb5Si3 phases showcase the orientation

Shuitu Baochi Xuebao, 2022 土壤板结是农田土壤退化问题之一,秸秆还田是提高土壤有机质含量、改良土壤的重要措施。但秸秆还田和土壤基质势对土壤板结的影响尚不明确。试验设0,3,5 g/kg 3个秸秆添加量处理,以及高(1 000 kPa)、中(100 kPa)、和低(10 kPa)3个土壤基质势处理。通过固结试验,测定不同处理的压缩曲线并计算压缩回弹特性指标。结果表明:秸秆添加量、土壤基质势及其二者间的交互作用对压缩曲线最大曲率、预固结压力值、压缩指数和回弹指数的影响都达到显著性水平。预固结压力值 ...

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Achieving a simultaneous enhancement of strength and ductility remains a critical bottleneck for the large‐scale and cost‐effective engineering application of magnesium alloys. In this work, guided by first‐principles calculations, we tailored the τ‐Mg32(Al,Zn)49 phase and optimised twin boundary, thereby designing and successfully ...

Journal of Linguistic Anthropology, Volume 35, Issue 2, August 2025.Abstract This article argues that social actors' media ideologies about digital interfaces are key to the enregisterment of online activities. Focusing on an online register emergent from user activities around Year, Hare, Affair (YHA)—a state‐aligned Chinese animation—I explore how different metadiscourses evaluate this register by entextualizing ...

Zhejiang Daxue xuebao. Lixue ban, 2022 采用智能感官分析技术结合传统感官评价，研究了细点圆趾蟹蟹肉、细点圆趾蟹重组蟹肉、仿蟹肉块和仿蟹肉棒的感官品质。4类均为低脂类、可放心食用的食品。用电子舌技术与主成分分析法对4类蟹肉样品进行了区分和识别，用质构仪检测了4类样品的适口性（包括硬度、弹性、黏结性、胶性、咀嚼性和回复性）。结果表明，仿蟹肉制品与纯蟹肉在味道上存在明显差异，纯蟹肉较仿蟹肉制品具有更强的鲜味回味，但苦味、涩味和苦味回味相对较高；蛋白质类添加剂（TG酶）有利于提高纯蟹肉的感官品质，尤其可大幅度改良口感和质地 ...

Rare Metals, Volume 43, Issue 8, Page 3702-3712, August 2024.Graphical abstract AbstractThe highly reversible insertion/extraction of large‐radius K+ into electrode materials remains a tough goal, especially for conversion‐type materials. Herein, we design a current collector‐integrated electrode (N–CoSe/CoSe2–C@Cu) as an advanced anode for potassium‐ion battery (PIBs).

多核白细胞弹性蛋白酶在白细胞介素-1诱导下对角膜基质细胞胶原降解的作用
Zhongguo shiyan zhenduanxue, 2006 目的观察多核白细胞弹性蛋白酶及白细胞介素-1α（Interleukin-1α,IL-1α）对人角膜基质细胞胶原降解作用的影响,探讨角膜溃疡的发生机理。方法角膜基质细胞三维胶原凝胶模型表面添加含多核白细胞弹性蛋白酶及IL-1α的MEM液,培养5天,通过测定培养液中的羟脯氨酸（HYP）的量作为胶原降解活性单位。结果多核白细胞弹性蛋白酶直接降解I型胶原,但对角膜基质细胞胶原降解无明显影响,同时添加弹性蛋白酶和IL-1α,明显增加角膜基质细胞胶原降解。结论多核白细胞弹性蛋白酶和IL ...

Integrative Conservation, Volume 3, Issue 1, Page 36-45, March 2024.Threatened and endangered species that occur in coastal areas are susceptible to the impacts of hurricanes that can destroy and reorganize their habitats. We used long‐term tracking of endangered beach mice to reveal they survive these impacts by using high elevation dune habitats to stay safe.
