Cr-Triggered Local Structural Change in Cr2Ge2Te6 Phase Change Material
, 2019 Cr2Ge2Te6 (CrGT) is a phase change material with higher resistivity in the crystalline phase than in the amorphous phase. CrGT exhibits an ultralow operation energy for amorphization.

分光光度法同时测定水中Cr(Ⅵ)、Cr(Ⅲ)和总铬的条件优化
Gongye shui chuli, 2007 实验中用过硫酸铵代替高锰酸钾将Cr(Ⅲ)氧化成Cr(Ⅵ),再与二苯碳酰二肼(DPCI)进行显色反应。利用Cr(Ⅵ)与DPCI的显色反应及可见光谱法建立了同时测定水样中痕量Cr(Ⅵ)和Cr(Ⅲ)的方法。用此方法对含有Cr(Ⅲ)和Cr(Ⅵ)的混合水样进行测定,分析效果良好。对影响各反应的条件及检测条件进行了优化研究,建立了快速、简便、可靠地测定水样中铬含量的方法。

Study on the removal of Cr(Ⅵ) by acid-modified distillers’ grains biochar
Gongye shui chuliThe acid modified biochar (H-BC) was prepared with distillers’ grains, which was activated by KHCO3 and modified by dipping in acid solution. By optimizing the preparation parameters of H-BC (pyrolysis temperature, activator ratio, type and concentration

Advanced Engineering Materials, EarlyView.Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated
