The electrochemical nitrogen reduction reaction (NRR) has been regarded as a promising alternative to the conventional Haber-Bosh process for NH3 synthesis. Inspired by the Fe-Mo-S cofactor in the enzyme nitrogenase, metal sulfide catalysts, mostly Fe- or Mo-based sulfides, have recently received ...
The compounds (NH4)3AsS4· 5 NH3 (1) and (NH4)3SbS4· 8 NH3 (2) were prepared by the reaction of Na3AsS4 and Na3SbS4 with a proton-charged ion exchange mat... F Eckart,W Ludwig - 《Zeitschrift Für Naturforschung B》 被引量: 0发表: 2003年 Vapour-Pressure Investigations of Impur...
As the oxidation reaction (first step) is self-limiting, the etch depth is no longer dependent on the etch time, but is dependent on the number of etching cycles. By repeating these two ner as shown schematically in steps, the Fig. 1. extremely scaled Ge or Ge1−xSnx fins can be...
In the process of reaction, both ammonia and carboxymethyl cellulose (CMC) play key roles in the formation of the nZunmxCbde1r−oxSf hollow structures. It is known that CMC is a kind of water soluble polyanionic compounds with a large carboxyl and hydroxyl groups. With the addition of ...

印制电路板废水处理工艺应针对下列主要污染物:Cu、COD、Ni、NH3-N、CN、酸碱等,应分别采用不同流程进行处理或预处理。 4.2 废水水量 设计废水量应根据项目环评报告及其批复环保意见或厂家给出的资料进行,无资料时可参考电路板产能进行估算:单面板按 t/m2;双面板按 t/m2;多层板按[~] t/m2;HDI板按[~] t/...
When the 6 M NH3 began to be added, the color shifted to dark purple color after 15 mL of ammonia and the amount of the precipitate was less. After 20 mL of ammonia, the solution became a red brown with very little of the blue precipitate. After 30 mL of ammonia, the solution was...
