Development of MoS2-TiO2/ PVDF-based hollow fibre membranes for membrane distillation desalination / Nurul Syazana Fuzil

Membrane distillation (MD) is a hybrid system that combines membrane technology with thermal distillation, which has recently emerged as one of the technologies used for seawater desalination. However, MD faced several limitations that hamper its comprehensive utilization for clean water production,...
