First observation of native ferroelectric metal

In a paper released today in Science Advances, Australian researchers describe the first observation of a native ferroelectric metal: a native metal with bistable and electrically switchable spontaneous polarization states—the ...

New molecular sieves

An international team of researchers recently synthesized polyarylether-based covalent organic frameworks, the most stable crystalline porous material on record. The team, which includes the University of Delaware's Yushan ...

New material also reveals new quasiparticles

Researchers at PSI have investigated a novel crystalline material that exhibits electronic properties that have never been seen before. It is a crystal of aluminum and platinum atoms arranged in a special way. In the symmetrically ...

Inorganic perovskite absorbers for use in thin-film solar cells

A team at the Helmholtz-Zentrum Berlin has succeeded in producing inorganic perovskite thin films at moderate temperatures using co-evaporation - making post-tempering at high temperatures unnecessary. The process makes it ...

Layered liquids arrange nanoparticles into useful configurations

Materials scientists at Duke University have theorized a new "oil-and-vinegar" approach to engineering self-assembling materials of unusual architectures made out of spherical nanoparticles. The resulting structures could ...

Turning buildings into energy producers

Photovoltaics can be used directly in building and renovation projects and serve as a construction material in their own right. Integrating solar panels into facades and roofs can transform buildings into electricity producers ...

Anti-fatigue-fracture hydrogels

Hydrogels are polymer networks infiltrated with water, widely used for tissue engineering vehicles of drug delivery and novel platforms for biomedical engineering. Emerging applications for new hydrogel materials call for ...
