‘Dope’ finding could produce faster semiconductors

Researchers have found another reason why semiconductors lose their ability to carry a charge as they become more densely ‘doped’.

Proportional advance for solid-state electrolytes

By altering the proportion of the ingredients in a lithium-based material, scientists have found a good candidate for a solid-state electrolyte.

Scientists have shown that repeated cycles of heating and cooling offer a cheap way to produce single-crystal metals.

Windows coated with thermochromic vanadium dioxide nanoparticles can let heat in during winter and keep it out in summer.

Scientists have developed new materials for splitting water to create hydrogen and splitting carbon dioxide to create carbon monoxide.

By sandwiching rare earth metals between layers of graphene, scientists have been able to control its band gap.

A novel way to measure the band gap of the 2D material molybdenum disulfide has revealed the link between its electronic and optical properties.

Using nanorods and metal coatings, scientists have developed a new way of controlling the domain structure of ferroelectric materials.

Adding nanodiamonds to the electrolyte in lithium-ion batteries can help prevent the formation of short-circuiting dendrites.

Expanding the pores in a titanium disulfide cathode drastically increases the storage capacity of magnesium batteries.

Scientists have detected a rare state of matter known as ‘electronic nematic’, in which electrons in a superconducting crystal organize collectively.

Carbonated water offers a greener way to remove graphene produced by chemical vapor deposition from metal substrates.
