Shape matters for light-activated nanocatalysts

September 18, 2020

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

A model by Rice University scientists shows how two positively charged spheres attached to springs are attracted to the electric field of light. Due to the motion of the spheres, the spring system scatters light at different energies when irradiated with clockwise and anticlockwise trochoidal waves.

Cartwheeling light reveals new optical phenomenon

June 29, 2020

Researchers at Rice University have discovered details about a novel type of polarized light-matter interaction with light that literally turns end over end as it propagates from a source.

Fluorocarbon bonds are no match for light-powered nanocatalyst

June 22, 2020

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.
