UT Arlington researchers use polyaniline to split CO2 into alcohols

Green Car Congress

Researchers at The University of Texas at Arlington have been the first to demonstrate that polyaniline (PANI), a member of the organic conducting polymer family, is a promising photocathode material for the conversion of carbon dioxide into alcohol fuels without the need for a co-catalyst.

Study shows uncovers how beetle gut microbes serve as reactor for fuel production

Green Car Congress

These insights into how the beetle and its distinct microbiome have co-evolved provide a roadmap for the production of affordable, nature-derived fuels and bioproducts. Understanding how evolution has solved the complex lignocellulose to fuel conversation process can help us design better industrial mimics and find novel enzymes or pathways.

IBM Research and Stanford researchers ID develop new catalyst for cheaper bioplastics

Green Car Congress

A team from IBM Research and Stanford University has identified a chemical catalyst that can be used to create cheaper, biodegradable plastics from plants such as palm trees and beets. The new catalyst is an organic substance that lowers the energy required for the conversion from plant to plastic to occur.

Roadmap shows how to improve lignocellulosic biofuel biorefining with high-value products from isolated lignin

Green Car Congress

This can happen either after removal of most of the carbohydrates by hydrolysis and fermentation operations (top sequence) or by pretreatment before downstream carbohydrate conversion (bottom sequence). Such insights may help redesign lignin within its cross-linked complex biological matrix to meet subsequent process and end product goals.

Argonne-led study insights help to reduce degradation in fuel cells and extend lifetime

Green Car Congress

Vehicles powered by polymer electrolyte membrane fuel cells (PEMFCs) are energy-efficient and eco-friendly, but despite increasing public interest in PEMFC-powered transportation, current performance of materials that are used in fuel cells limits their widespread commercialization. Lopes, P.P.,
