Rice U team creates low-cost, high-efficiency integrated device for solar-driven water splitting; solar leaf

Green Car Congress

Rice University researchers have created an efficient, low-cost device that splits water to produce hydrogen fuel. The module developed at Rice University can be immersed into water directly to produce fuel when exposed to sunlight. We simplify the system by encapsulating the perovskite layer with a Surlyn (polymer) film.

Researchers use melamine to create effective, low-cost carbon capture; potential tailpipe application

Green Car Congress

Using an inexpensive polymer called melamine, researchers from UC Berkeley, Texas A&M and Stanford have created a cheap, easy and energy-efficient way to capture carbon dioxide from smokestacks. The low cost of porous melamine means that the material could be deployed widely.

UCalgary, Rice team uses flash joule heating to manufacture graphene from petroleum waste

Green Car Congress

A team from the University of Calgary and Rice University has used flash joule heating (FJH) ( earlier post ) to convert low-value asphaltenes—a by-product of crude oil refining—into a high-value carbon allotrope, asphaltene-derived flash graphene (AFG). Flash graphene from asphaltenes. (A) —Saadi et al.

New multifunctional polymer binder achieves theoretical capacity of LiFePO4 Li-ion batteries without additives

Green Car Congress

Researchers led by a team from Griffith University in Australia have developed a multifunctional polymer binder that not only maintains the outstanding binding capabilities of sodium alginate but also enhances the mechanical integrity and lithium-ion diffusion coefficient in a LiFePO 4 (LFP) electrode during the operation of the batteries.
