Research on the Detoxification of Municipal Solid Waste Incineration Fly Ash: Organic Acid Washing Pretreatment Coupled With Cement/DDTC Stabilization

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Heavy metals in municipal waste incineration fly ash are potentially harmful to the ecological environment and human health. To mitigate the hazards of fly ash, this study attempts to detoxify fly ash through organic acid washing pretreatment coupled with cement/sodium diethyldithiocarbamate (DDTC) solidification.

Copper‐doped borosilicate bioactive glass coating modified bacterial cellulose functional dressing for diabetic ulcer

open access: yesBMEMat, EarlyView.
For the first time, a borosilicate‐based bioactive glass coating was successfully formed on the surface of bacterial cellulose nanofibers. A copper‐doped borosilicate bioactive glass coating‐modified bacterial cellulose functional dressing was designed for the management of chronic wounds, such as diabetic ulcers.
