为了解蛇纹石矿物在全球碳循环中的作用,我们以二氧化碳(CO2)为压力介质,对蛇纹石[Mg3Si2O5(OH)4]进行了高压X射线衍射(XRD)实验研究。同步辐射XRD图谱表明,在170 ℃和2.5(1) GPa条件下,样品加热1 h后形成了菱镁矿和纤蛇纹石高压相。Rietveld精修结果表明,在菱镁矿形成时,初始的纤蛇纹石晶胞组成变为Mg2.4(1)Si2O5(OH)2.4(1),这似乎是由于最内层羟基(OH3)的脱氢和M1位置上镁元素的重新排布,从而导致亚稳态单层脱羟基纤蛇纹石的形成。亚稳态纤蛇纹石压力和温度测量至5.0(1) GPa和500 ℃,这与苏门答腊南部和琉球俯冲带所在的莫霍板块地热温压条件相对应。在恢复到常温常压条件后,最初的纤维状纤蛇纹石已转变为土状。这些结果可以帮助我们了解沿俯冲带分布的深部碳循环作用过程,并可能促使设计利用压力和温度对石棉解毒的一种新方法。

PFRs were produced on biochar during Cr(VI) decontamination. PFRs formation on biochar was owing to the oxidization of phenolic-OH by Cr(VI). Appearance of excessive oxidant led to the consumption of PFRs on biochar. Biochar charred at high temperature possessed great performance to Cr(VI) removal.

Ionically Imprinting-Based Copper (Ⅱ) Label-Free Detection for Preventing Hearing Loss Article

Copper is a microelement with important physiological functions in the body. However, the excess copper ion (Cu2+) may cause severe health problems, such as hair cell apoptosis and the resultant hearing loss. Therefore, the assay of Cu2+ is important. We integrate ionic imprinting technology (IIT) and structurally colored hydrogel beads to prepare chitosan-based ionically imprinted hydrogel beads (IIHBs) as a low-cost and high-specificity platform for Cu2+ detection. The IIHBs have a macroporous microstructure, uniform size, vivid structural color, and magnetic responsiveness. When incubated in solution, IIHBs recognize Cu2+ and exhibit a reflective peak change, thereby achieving label-free detection. In addition, benefiting from the IIT, the IIHBs display good specificity and selectivity and have an imprinting factor of 19.14 at 100 lmol∙L–1. These features indicated that the developed IIHBs are promising candidates for Cu2+ detection, particularly for the prevention of hearing loss.
