On taking a closer look at how nonuniform particles self-assemble, engineers were surprised to discover that it happens in multiples phases.

Researchers have shown that a nano-coating of boron nitride can stabilize solid electrolytes in lithium metal batteries.

Researchers have discovered why vanadium disulfide is unstable as a battery cathode material and developed a way to make it more stable.

Researchers have not only unexpectedly detected polar skyrmions in a material with reversible electrical properties, but also found that they're chiral.

Applying high pressures and temperatures to elements like potassium and sodium produces a new, stable state of matter that is both solid and liquid.

A coating of graphene can stop oxygen escaping from the cathode of a lithium battery, helping to prevent the battery from catching fire.

Scientists have developed a model for predicting the shape of metal ‘islands’ sandwiched between or below 2D materials such as graphene.

Scientists used advanced microscopy to monitor atoms as they rearrange in real-time during the synthesis of intermetallic nanoparticles.

A hot-drawing technique for processing plastics can create transparent polythene film that is stronger than aluminium but a fraction of the weight.

An environmentally friendly deep eutectic solvent can extract valuable elements from the metal oxides commonly used as cathodes in lithium-ion batteries.

Researchers have developed a 'hybrid' cathode for lithium-sulfur batteries that combines an intercalation type material with a conversion type material.

Scientists have found a way to place catalysts inside the tiniest pores of different host materials, a bit like fitting a model ship inside a bottle.

Scientists have theorized a new ‘oil-and-vinegar’ approach for inducing spherical nanoparticles to self-assemble into unusual architectures.
