Elastomers that replicate complex twisting action just through the use of light

Using rapid, powerful bursts of light, scientists have uncovered evidence of Rashba effects in bulk organometallic halide perovskites.

By stretching hexagonal boron nitride, scientists have obtained the largest spectral color-tuning range from an atomically thin quantum system.

Researchers have developed a carbon nanotube-based sensor that can track how plants respond to stresses such as injury, infection and light damage.

The traps that capture charge carriers in perovskite crystals occur at the boundaries between distorted grains and pristine grains.

data can be written and erased in novel light-emitting hybrid combining bioimaging organic dyes and luminescent solid-state metal clusters

Researchers have designed a novel liquid crystal elastomer that can be ‘programmed’ to both twist and bend in the presence of light.

Researchers have developed an hexagonal silicon-germanium alloy that can emit light, which could prove of great use for photonics.

Researchers have developed a novel machine-learning algorithm for quantitatively characterizing material microstructure in three dimensions.

When heated, a novel photonic crystal appears to emit more coherent light at infrared wavelengths than can be explained by Planck's Law.

Sheets that are just a single molecular layer thick could be used to detect toxic gases

Researchers have demonstrated that solar cells made from organic materials may be better than traditional silicon solar cells for use underwater.
