An
inexpensive method for generating clean fuel is the modern-day
equivalent of the philosopher’s stone. One compelling idea is to use
solar energy to split water into its constituent hydrogen and oxygen and
then harvest the hydrogen for use as fuel. But splitting water
efficiently turns out to be not so easy. - Read more here

Molecular footballs could revolutionize your next World Cup experience
A new way to assemble
individual molecules could revolutionize the creation of novel materials
with numerous potential applications, including emerging technologies
such as flexible TVs. The results of this ground-breaking research are
published on 22 June in the prestigious journal Nature Chemistry.

Evolution of a bimetallic nanocatalyst
Atomic-scale
snapshots of a bimetallic nanoparticle catalyst in action have provided
insights that could help improve the industrial process by which fuels
and chemicals are synthesized from natural gas, coal or plant biomass. A
multi-national lab collaboration led by researchers with the U.S.
Department of Energy (DOE)’s Lawrence Berkeley National Laboratory
(Berkeley Lab) has taken the most detailed look ever at the evolution of
platinum/cobalt bimetallic nanoparticles during reactions in oxygen and
hydrogen gases.

New fluorescent hybrid material changes color according to direction of light
The UPV/EHU's Molecular Spectroscopy Group, in collaboration with the
Institute of Catalysis and Petroleum Chemistry of the CSIC (Spanish
National Research Council), has developed a highly fluorescent hybrid
material that changes colour depending on the polarisation of the light
that it is illuminated by.
The research has been published in ACS
Photonics, the new journal devoted exclusively to Photonics published by
the American Chemical Society.
The aim with respect to hybrid materials with one organic component
and another inorganic one is to combine the best attributes of each one
into a single system.
Labs across the world are working to develop new
hybrid materials for technological applications in nanotechnologies, in
particular, and these materials are already being used in lightweight
materials for cars, sports equipment, in biomimetic materials, like
prostheses, etc.

Steering Chemical Reactions with Laser Pulses
Usually, chemical reactions just take their course, much like a ball
rolling downhill.
However, it is also possible to deliberately control
chemical reactions: at the Vienna University of Technology, molecules
are hit with femtosecond laser pulses, changing the distribution of
electrons in the molecule.
This interaction is so short that at first
it does not have any discernable influence on the atomic nuclei, which
have much more mass than the electrons. However, the disturbance of the
electron distribution can still initiate chemical processes and
eventually separate the nuclei from each other.
The properties of the
laser pulse determine which chemical final products are created.

PNNL: News - Halving hydrogen
PNNL: News - Halving hydrogen
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 provides insight into how to make the catalyst work better for alternative energy uses.
This study is the first time scientists have shown precisely where the hydrogen halves end up in the structure of a molecular catalyst that breaks down hydrogen, the team reported online April 22 in Angewandte Chemie International Edition.
The design of this catalyst was inspired by the innards of a natural protein called a hydrogenase enzyme.

Neutron crystallography shows this iron catalyst gripping two hydrogen atoms (red spheres). This arrangement allows an unusual dihydrogen bond to form between the hydrogen atoms (red dots). |
