Shape matters for light-activated nanocatalysts

Points matter when designing nanoparticles that drive important chemical reactions using the power of light, according research from Rice University's Laboratory for Nanophotonics.

Atoms in the crystal lattice of tantalum disulfide arrange themselves into six-pointed stars that can be manipulated by light, according to Rice University researchers. The phenomenon can be used to control the material’s refractive index. It could become useful for 3D displays, virtual reality and in lidar systems for self-driving vehicles.

Ambient light alters refraction in 2D material

Microscopic crystals in tantalum disulfide have a starring role in what could become a hit for 3D displays, virtual reality and even self-driving vehicles.

No limit yet for carbon nanotube fibers

Rice University researchers report advances in their quest to make the best carbon nanotube fibers for industry.

Naomi Halas is a Rice University engineer and chemist who's spent more than 25 years pioneering the use of light-activated nanomaterials.

Purifying water with a partly coated gold nanoparticle

Rice's Naomi Halas has collaborated with Yale University engineers on the creation of a light-activated nanoparticle for clearing water of pollutants. The research is part of an effort by NEWT, the Rice-based Nanosystems Engineering Research Center for Nanotechnology-Enabled Water Treatment.

Fluorocarbon bonds are no match for light-powered nanocatalyst

Rice University engineers have created a light-powered catalyst that can break the strong chemical bonds in fluorocarbons, a group of synthetic materials that includes persistent environmental pollutants.
