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 ...

Imperfection is OK for better MOFs

Perfect crystals are not necessarily the most useful. Defects in the ordered crystalline structure of metal-organic frameworks (MOFs) could tailor these versatile materials for specific applications. KAUST researchers have ...

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 ...

Crystal clear solvent filtration

Covalent organic materials with well-ordered porous microstructures could provide the membranes needed for technology to meet increasingly stringent environmental controls and be cost effective to produce.

Intuition and failure are valuable ingredients in chemistry

When researchers make a new discovery, they tend to only publish the results of their successful experiments. But just as informative are all the experiments that didn't work – the failed trials and incorrect hypotheses, ...

Modular construction—on a molecular scale

Modular constructions from cages (proteins), hubs (metal ions), and struts (organic linkers) allows the rational design of porous scaffolds. The inherent chemical and structural diversity of these building blocks leads to ...

New ways of looking at glass-to-metal seals

Components housed in stainless steel for protection against extreme environments seen in the aerospace and defense industries require paths for electricity to power them and communicate with them. Those paths in turn need ...

Making sense of metallic glass

If you freeze any liquid fast enough, even liquid metal, it becomes a glass. Vitrified metals, or metallic glasses, are at the frontier of materials science research. They have been made by rapidly cooling alloys of various ...
