Study on the vitrification of rat embryonic cerebral cells(大鼠胚脑细胞玻璃化冷冻保存研究)
Zhejiang Daxue xuebao. Lixue ban, 2005 在20 ℃室温下，用玻璃化冻存液（含5.5 mol/L乙二醇和1 mol/L蔗糖）对大鼠胚脑细胞进行一步法和两步法深低温保存.在冻存1、3、7、15 d后，37 ℃水浴快速复温，洗脱冻存保护剂，检测细胞活性.结果表明：两步法0.5 min平衡组，在玻璃化冻存15 d后，胚脑细胞的存活率和SDH活性分别为(78.6±3.3)% 和0.69±0.05，细胞活性水平最高.此外，一步法1 min平衡组，冻存15 d后，细胞活性也较高，细胞存活率和SDH活性分别为(77.9±4.7)% 和0.68±0.04 ...

Zhejiang Daxue xuebao. Lixue ban, 2023 在埋藏过程中，随着埋深的增加，细粒沉积岩的矿物组成、有机质形态、孔隙类型与质量分数等会发生一系列变化。为揭示其变化规律，对有机质热模拟的残样进行了扫描电镜、全岩X射线衍射、镜质体反射率（Ro）、岩石热解、有机碳质量分数等测试。发现在从室温（25 ℃）到550 ℃的升温过程中，有机质形态由团块状向条带状、团块状变化；黏土矿物由层片状逐渐向絮状转化；碳酸盐矿物溶蚀加剧，温度超过500 ℃后，出现溶蚀-沉淀现象；随着温度的升高，由有机质热演化产生的有机质孔的面积不断增加，在450~475 ℃时 ...

Effects of Warming and Sea-level Rise on the Growth of Kandelia obovata and Laguncularia racemosa Seedlings [PDF]
, 2013 据政府间气候变化专门委员会（IPCC）估计，未来二十年全球平均气温将以每十年增加大约0.2ºC的速率变暖。未来100年全球平均气温大约上升2oC。全球变暖引起海洋自身的热膨胀与陆地上冰川、冰帽、极地冰盖的消融，导致海平面上升。根据中国国家海洋局公报，未来100年我国沿海海平面上升幅度约为30cm。红树林是分布在热带和亚热带海岸潮间带的木本植物群落，它将首当其冲受到全球气候变化的影响：既受到气温上升的影响，又同时受到海平面上升的影响。全球气温升高和海平面上升对红树林的影响是交互的。 秋茄 ...

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Developing oxygen evolution reaction (OER) catalysts that combine high performance with cost‐effectiveness is a critical challenge for advancing the commercialization of anion exchange membrane water electrolysis (AEMWE). Practical application is often hindered by issues such as poor batch reproducibility and low‐cost efficiency.

Jianzhu Gangjiegou Jinzhan, 2019 局部火灾下,网架结构升温具有明显的非均匀性,结构中温度高的杆件热膨胀受到温度较低杆件的约束,使得网架结构的部分杆件具有显著的约束杆件高温力学特征。基于局部火灾下网架结构力学反应全过程数值追踪技术,考察结构升温非均匀性、结构荷载比、火源位置和结构跨度影响因素下,网架结构杆件高温屈曲后强度对整体结构抗火极限承载力的贡献。研究表明:当结构温度分布非均匀系数η在0.2≤η0.5时,杆件高温屈曲后强度对结构抗火极限承载力的贡献先逐渐减小然后转变为逐渐增大。上述研究结论可为建立网架结构第2阶段失效准则提供理论依据。

Creep characteristics of sandstone during freezing/thawing process [PDF]
The rock mass in cold regions is always subjected to the load and freeze-thaw. If the impact of long-term freeze-thaw mechanical behavior on sandstone mass is neglected, it would lead to significant hazards to the construction and safe operation of ...

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Metal oxide‐based catalysts for oxygen reduction reaction (ORR) have drawn great attention in recent years. However, it remains technically challenging for the precise regulation of the overall performance due to the trade‐off effect among the activity, selectivity, and stability of electrocatalysts. Herein, a balancing strategy to control the

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Driven by global energy transition and sustainability, sodium‐ion batteries (SIBs) have emerged as key alternatives to lithium‐ion batteries for low‐to‐medium energy storage, because of abundant sodium resources and low cost. However, their commercialization is hindered by the lack of anodes with high capacity, fast kinetics, and long‐term ...
