Proving nanoparticles in sunscreen products

Cosmetics increasingly contain nanoparticles. One especially sensitive issue is the use of the miniscule particles in cosmetics, since the consumer comes into direct contact with the products. Sunscreen lotions for example have nanoparticles of titanium oxide. They provide UV protection: like a film made of infinite tiny mirrors, they are applied to...

Researchers demystify the ferroelectric properties observed in hafnium-oxide-based thin films

Ferroelectric materials have applications in next-generation electronics devices from optoelectronic modulators and random access memory to piezoelectric transducers and tunnel junctions. Now researchers at Tokyo Institute of Technology report insights into the properties of epitaxial hafnium-oxide-based (HfO2-based) thin films, confirming a stable...
