Cleaning a fouled membrane using warm water, instead of commonly used fouling control chemicals, is an approach advocated in resource-limited settings, where small-scale membrane filtration is used to provide clean water. Thermoresponsive polymers coated onto membranes undergo a conformational change across their lower critical solution temperature (LCST), enabling foulant removal during such temperature-swing cleaning. However, their intrinsic hydrophobicity above the LCST poses a fundamental m

Waterborne pathogens pose a major threat to global water safety. Solar energy could provide a critical opportunity for households without reliable access to safe water; however, many solar-driven household water treatment systems (HWTS) fail to provide adequate year-round quantities of clean drinking water, as they often cannot remove viruses during low-sun periods, exposing users to waterborne diseases. We demonstrate the disinfection capacity of a novel concentrating solar water-energy managem
