A wearable device for regrowing hair

Although some people embrace the saying "bald is beautiful," for others, alopecia, or excessive hair loss, can cause stress and anxiety. Some studies have shown that stimulating the skin with lasers can help regrow hair, ...

Understanding origami in 2-D materials

One in five mobile phone users in the UK have cracked their screen by dropping the phone in a three year period, according to a YouGov poll. The mobile screens break easily because they are usually made from an oxide material ...

Nanoparticles form supercrystals under pressure

Self-assembly and crystallisation of nanoparticles (NPs) is generally a complex process, based on the evaporation or precipitation of NP-building blocks. Obtaining high-quality supercrystals is slow, dependent on forming ...

Getting an up-close, 3-D view of gold nanostars

Extremely small structures, far smaller in diameter than a strand of hair, could greatly benefit sensors and other devices. To master these nanomaterials, scientists need to determine their shape. That's difficult. Scientists ...

Why size matters for gold as a catalyst

Gold is the noblest metal—the most resistant to oxidation. However, nano-size gold has a unique ability to perform as a catalyst, even at low temperatures. The underlying mechanism for this size-dependent change in properties ...

Lab probes molecular limit of plasmonics

Rice University researchers are probing the physical limits of excited electronic states called plasmons by studying them in organic molecules with fewer than 50 atoms.
