Defect-filled lead-halide perovskites rival silicon solar cells because domain walls inside the material separate and guide charges. Researchers visualized these charge-transport networks using a ...

If we are to prevent the impending environmental crisis, it is imperative that we find efficient and sustainable ways to avoid being wasteful. One area with much room for improvement is the recycling ...

The study of curvature effects on crystal structures and defect dynamics offers pivotal insights into how geometric constraints influence material properties at the micro‐ and nanoscale. Curved ...

Quantum engineers have spent years trying to tame the fragility of qubits, only to be thwarted by the tiniest imperfections in the materials they use. Now a new line of research flips that problem on ...

Light can hit a lead halide perovskite crystal that is anything but pristine and still end up as useful electric current.

Electron diffraction is a powerful analytical technique used to study the atomic structure of materials. It involves the interaction of a beam of electrons with a crystalline sample, resulting in a ...

A team of researchers has discovered an effective method for removing lattice defects from crystals. A team of researchers from Osaka University, the Institute for High Pressure Physics and the ...

Despite being riddled with impurities and defects, solution-processed lead-halide perovskites are surprisingly efficient at converting solar energy into electricity. Their efficiency is approaching ...

Using two-photon excitation, Japanese scientists have, for the first time, observed the internal defects of semiconductor crystals in three-dimensions. Having studied defects to a depth of 200 µm in ...

Controlling the transport properties through a zeolite and the rates of diffusion and size of molecules that can be stored or transported are key in developing and optimizing zeolites for various ...

(Nanowerk Spotlight) The petrochemical industry relies on separating chemicals that differ by just fractions of a nanometer in size. Methanol must be purified from similarly-sized molecules in the ...
