Physicists develop new material for water desalination

Titanium dioxide nanoparticles with gold absorb about 96% of the solar spectrum and turn it into heat. The material can accelerate the evaporation in desalination plants up to 2.5 times and can track hazardous molecules and ...

Tuning tubes for better catalysts

Titanium dioxide (TiO2) has considerable power as a photocatalyst—a material that captures light energy to accelerate chemical reactions that are otherwise difficult to achieve. One of its most promising applications is ...

No nanoparticle risks found in field tests of spray sunscreens

People can continue using mineral-based aerosol sunscreens without fear of exposure to dangerous levels of nanoparticles or other respirable particulates, according to Penn State research published in the journal Aerosol ...

Lighting the path to recycling carbon dioxide

Semiconductive photocatalysts that efficiently absorb solar energy could reduce the energy required to drive a bioelectrochemical process that converts CO2 emissions into valuable chemicals, KAUST researchers have shown.
