A new type of activated carbon immobilized copper(Cu/AC)photocatalyst was prepared by a facile impregnation-adsorption method,where Cu2+is chemically adsorbed b
A new ZnS/CdS heterojunction is constructed through the direct sulfurization of a metal ions exchanged Zn/Cd-MOF precursor(MOF=metal-organic framework material)
High-performance self-cleaning coatings are highly desired by the industry and market.Herein,we synthesized two kinds of ultrafine TiO2 nanocrystals,one is anat
We investigate Whittle index policy for a restless bandit model whose state space may be enlarged under passive actions.This model arises in many important ap-p
