Chemists find new way to do light-driven reactions in solar energy quest

The more efficient method opens another possible pathway to harness sunlight for energy

10-Aug-2015

Chemists have found a new, more efficient method to perform light-driven reactions, opening up another possible pathway to harness sunlight for energy. The journal Science is publishing the new method, which is based on plasmon - a special motion of electrons involved in the optical properties of ...

NIST calculates high cost of hydrogen pipelines, shows how to reduce it

22-Jul-2015

The National Institute of Standards and Technology (NIST) has put firm numbers on the high costs of installing pipelines to transport hydrogen fuel - and also found a way to reduce those costs.Pipelines to carry hydrogen cost more than other gas pipelines because of the measures required to ...

The simplest element: Turning hydrogen into 'graphene'

18-Dec-2014

New work from Carnegie's Ivan Naumov and Russell Hemley delves into the chemistry underlying some surprising recent observations about hydrogen, and reveals remarkable parallels between hydrogen and graphene under extreme pressures. Their work is the cover story in the December issue of Accounts ...

A new solution for storing hydrogen fuel for alternative energy

23-May-2014

Turning the "hydrogen economy" concept into a reality, even on a small scale, has been a bumpy road, but scientists are developing a novel way to store hydrogen to smooth out the long-awaited transition away from fossil fuels. Their report on a new solid, stable material that can pack in a large ...

Chemists challenge conventional understanding of how photocatalysis works

New model proposed by UC Riverside researchers could help identify better promoters for photocatalysis

21-May-2014

Photocatalysis is a promising route to convert solar energy into chemical fuels. Particularly appealing is the possibility to use photocatalysis to split water molecules into molecular hydrogen. Although photocatalysis has been around for many years, the search for viable photocatalysts to ...

Halving hydrogen

First view of nature-inspired catalyst after ripping hydrogen apart provides insights for better, cheaper fuel cells

25-Apr-2014

Like a hungry diner ripping open a dinner roll, a fuel cell catalyst that converts hydrogen into electricity must tear open a hydrogen molecule. Now researchers have captured a view of such a catalyst holding onto the two halves of its hydrogen feast. The view confirms previous hypotheses and ...

MRI, on a molecular scale

Researchers develop system that could one day peer into the atomic structure of individual molecules

23-Apr-2014

For decades, scientists have used techniques like X-ray crystallography and nuclear magnetic resonance imaging (NMR) to gain invaluable insight into the atomic structure of molecules, but such efforts have long been hampered by the fact that they demand large quantities of a specific molecule and ...
