晶体的结构相变是在温度、压力等外界因素刺激下发生的成分不变的结构转换现象。在相变的过程中,结极单元的重排或运动可能导致材料在高低介电态之间发生可逆转换,形成介电开关[1,2,3]。

A primary capacity of 9420 mA h g-1 under 1 atm of oxygen was achieved in a Li-O2 battery based on the robust Mn-MOF-74,more than four times higher than the value obtained in a cell without an MOF.
The control of the Ru(Ⅲ/Ⅱ)redox potential is critical in many optoelectronic applications,which can be achieved by changing the electronic nature of auxiliary ligands [1].
结构相变行为是具有重要理论研究意义和实用价值的一种临界现象。材料发生相变时,某些物理性质如二阶非线性光学性质、电导率、磁化率或介电常数常会发生突变,从而使其在光学传感、信息储存、磁电开关等方面具有潜在的应用 [1,2]。
谷胱甘肽(GSH)存在于几乎身体的每一个细胞，对维持人体正常生理功能起着重要作用，包括保持正常的免疫系统的功能、信号传导、解毒和基因调控等.GSH水平异常或者GSH及其氧化型谷胱甘肽二硫化物(GSSG)之间浓度失衡通常是一些疾病的先兆，如人类免疫缺陷病毒，肝损伤，阿尔茨海默病，炎症和心血管疾病等.
