DOI: 10.1016/j.jeurceramsoc.2017.12.012
Abstract: Abstract Macroporous ceramic membranes with hierarchical pore structure were developed and characterized for the time-integrated analysis of water contaminants. The alumina membranes were boosted to allow a suitable diffusion rate for envisaged applications. Sacrificial fugitives… read more here.

DOI: 10.1021/acsami.7b00705
Abstract: Permeable membranes are indispensable for in vitro epithelial barrier models. However, currently available polymer-based membranes are low in porosity and relatively thick, resulting in a limited permeability and unrealistic culture conditions. In this study, we… read more here.
