Researchers from the Faculty of Engineering at Universiti Malaysia Sabah (UMS) fabricated carbonized sawdust/barium titanate composite using a sol-gel method, which was later incorporated into cotton substrate by using a dip-coating process to produce a solar absorber.

In this article, we take a closer look at a research on coalescence of oil droplets using microporous membranes. In the case of oil-water emulsion, the separation by using the polymeric microporous membrane behaves differently and molecular sieving mechanism may not be applicable. Oil droplets in water are instable and tend to coalesce to form larger droplets. Contrarily, smaller oil droplets are more stable and the leaning to merge with each other is low.
