Jianjun Tian,Jianjun Tian,Rui Gao,Qifeng Zhang,Shengen Zhang,Yanwei Li,Jo-Lin Lan,Xuanhui Qu,Guozhong Cao +8 more
TL;DR: In this article, the authors optimized the thickness and porosity of TiO2 mesoporous film for better distribution of quantum dots to enhance the performance of CdS/CdSe quantum dot cosensitized solar cells.
Journal ArticleDOI
Supply and demand of some critical metals and present status of their recycling in WEEE.
TL;DR: It is found that the demand of indium, REEs, lithium and cobalt in EEE will continuously increasing, while precious metals are decreasing because of new substitutions with less or even without precious metals.
Journal ArticleDOI
The mechanisms of heavy metal immobilization by cementitious material treatments and thermal treatments: A review.
TL;DR: Converting heavy metals into more stable phases during immobilization processes should be a common way to enhance the immobilization effect of these immobilization methods.
