一般描述

1,2-二氯乙烷(二氯乙烯,DCE)是一种溶剂。它是氯乙烯制造业(EDC-tar)释放的降解副产物之一。它的诱变活性已在鼠伤寒沙门氏菌TA 1535上进行了检测。已对其在二氧化钛/二氧化硅(酸催化剂)上的催化降解进行了研究。

应用

1,2-二氯乙烷(二氯乙烯,DCE)已用于制造Cl掺杂的少层WS2或MoS2后栅极场效应晶体管(FET)期间的化学掺杂。它可以用作产乙烯脱卤拟球菌195的培养基中的电子受体。它可以在各种研究中用作氯化有机物的模型化合物。

Immuno-EM is a method that can determine the localization of a protein in a tissue at the ultrastructural level. Generally, membrane structures in immuno-EM specimens have very low contrast because fixation is performed without osmium. Here, by using high-angle annular

Low-resistivity metal-semiconductor (M-S) contact is one of the urgent challenges in the research of 2D transition metal dichalcogenides (TMDs). Here, we report a chloride molecular doping technique which greatly reduces the contact resistance (Rc) in the few-layer WS2 and MoS2.

"Dehalococcoides ethenogenes" 195 can reductively dechlorinate tetrachloroethene (PCE) completely to ethene (ETH). When PCE-grown strain 195 was transferred (2% [vol/vol] inoculum) into growth medium amended with trichloroethene (TCE), cis-dichloroethene (DCE), 1,1-DCE, or 1,2-dichloroethane (DCA) as an electron acceptor, these chlorinated
