Portable Photoelectrocatalytic Device for Water Disinfection
­Bacteria, viruses, and other harmful microorganisms pose a significant pathogenic health-related risk to safe drinking water. Disinfection by chlorination is commonly practiced, however, chlorine is a toxic chemical that typically requires careful storage and proper handling. While ultraviolet (UV) disinfection can be effective, UV-based processes...

Metal Matrix-Hydrophobic Nanoparticle Composites for Promoting Dropwise Condensation
Water vapor condensation is an essential aspect of many technologies in energy generation, desalination, and air conditioning. An increased heat transfer rate during water vapor condensation could lead to considerable economic savings as well as environmental benefits. Hydrophobization improves heat transfer by switching the condensation mode from filmwise...
