Medium-entropy oxides(MEOs)with broad compositional tunability and entropy-driven structural stability,are receiving booming attention as a promising candidate for oxygen evolution reaction(OER)***,ultrathin two-dimensional(2D)nanostructure offers extremely large specific surface area and is therefore considered to be an ideal catalyst ***,it remains a grant challenge to synthesize ultrathin 2D MEOs due to distinct nucleation and growth kinetics of constituent multimetallic elements in 2D anisotropic *** this work,an ultrathin 2D MEO(MnFeCoNi)O was successfully synthesized by a facile and low-temperature ionic layer epitaxy *** from multi-metal synergistic effects within ultrathin 2D nanostructure,this 2D MEO(MnFeCoNi)O revealed excellent OER electrocatalytic performance with a quite low overpotential of 117 mV at 10 mA·cm^(-2) and an impressive stability for 120 h continuous operation with only 6.9%***,the extremely high mass activity(5584.3 A·g^(-1))was three orders of magnitude higher than benchmark RuO_(2)(3.4 A·g^(-1))at the same overpotential of 117 *** work opens up a new avenue for developing highly efficient and stable electrocatalysts by creating 2D nanostructured MEOs.

钙稳态失衡与心房颤动介导的心肌病的关系

实用心脑肺血管病杂志 2024年第1期32卷 119-121,128页

心房颤动介导的心肌病(AMC)指阵发性或持续性心房颤动(AF)引起心脏扩大,导致心室收缩与舒张功能受损、左心室射血分数下降,最终引发心力衰竭(HF),患者恢复窦性心律或心室率得到严格控制后,心脏扩大与HF症状能够得到完全性或几乎完全性... 详细信息

心房颤动介导的心肌病(AMC)指阵发性或持续性心房颤动(AF)引起心脏扩大,导致心室收缩与舒张功能受损、左心室射血分数下降,最终引发心力衰竭(HF),患者恢复窦性心律或心室率得到严格控制后,心脏扩大与HF症状能够得到完全性或几乎完全性逆转。临床中AMC的发病率并不低,早期诊断、干预可以明显改善患者预后,但目前临床在排除其他病因后才能诊断AMC,缺乏特异性诊断指标,且对于AMC的病理过程尚不清楚。本文从钙稳态失衡入手,分别介绍了其在AF和HF中的作用,进而分析其与AMC的关系,以期为AMC的临床诊断和治疗提供方向。

通过掺入气密剂,配制适用于瓦斯隧道的气密性机制砂混凝土,并研究其对水泥水化的影响,运用等温量热仪、X射线衍射仪、热重分析仪、扫描电镜和压汞法对水泥水化放热及水化产物进行分析。结果表明:相较未掺时,掺入气密剂混凝土表观渗透率由497.50×10^(-18) m^(2)减小为29.16×10^(-18) m^(2),抗氯离子渗透系数减小了54.96%,56 d干燥收缩减小了8.63%,56 d抗压强度提高了11.2%。掺加气密剂对水泥净浆水化产物的生成无不利影响,同时明显减少了水泥净浆水化产物内部的大毛细孔(100~1000 nm)数量,使水化产物更密实,并改善了混凝土界面过渡区结构,从而提高了混凝土的强度、气密性及耐久性。
