Why gold-palladium alloys are better than palladium for hydrogen storage

11-Jul-2018

Materials that absorb hydrogen are used for hydrogen storage and purification, thus serving as clean energy carriers. The best-known hydrogen absorber, palladium (Pd), can be improved by alloying with gold (Au). New research led by The University of Tokyo Institute of Industrial Science explains ...

Efficient synthesis of multi-substituted anilines by domino rearrangement

05-Jul-2018

Anilines have been widely used in medicine, in particular in acetaminophen pain killers. They are also used in organic materials, such as liquid crystals and organic light-emitting diodes. The ability to efficiently synthesize a new class of aniline derivatives will enable further developments in ...

Catalyst upgrades carbon dioxide to fuels

28-Jun-2018

Liquid multi-carbon alcohols such as ethanol and n-propanol are desired as renewable transportation fuels. They offer high energy densities, ease of long-range transport, and direct drop-in usage in existing internal combustion engines. Engineering catalysts that favor high-value alcohols is ...

Reducing CO2 with common elements and sunlight

28-Jun-2018

An international collaborative research group including Tokyo Institute of Technology, Universite PARIS DIDEROT, and CNRS has discovered that CO2 is selectively reduced to CO when a photocatalyst composed of an organic semiconductor material and an iron complex is exposed to visible light. They ...

Modern alchemists are making chemistry greener

18-Jun-2018

Ancient alchemists tried to turn lead and other common metals into gold and platinum. Modern chemists in Paul Chirik's lab at Princeton are transforming reactions that have depended on environmentally unfriendly precious metals, finding cheaper and greener alternatives to replace platinum, ...

A splash of detergent makes catalytic compounds more powerful

05-Jun-2018

Researcher David Rosenberg examines images of a white powder under a powerful scanning electron microscope. Up close, the powder looks like coarse gravel, a heap of similar but irregular chunks. Then he looks at a second image — the same material produced by colleague Hongyou Fan instead of ...

A path to sustainable and biodegradable polyesters

04-Jun-2018

There's a good chance you've touched something made out of the polyolefin polymer today. It's often used in polyethylene products like plastic bags or polypropylene products like diapers. As useful as polyolefins are in society, they continue to multiply as trash in the environment. Scientists ...

Magic in metal could help put excess carbon dioxide to good use

01-Jun-2018

The chunk of metal sitting on a table in Joel Rosenthal's office at the University of Delaware looks like it should belong in a wizard's pocket. Shiny silver with shocks of pink and splashes of gold, it's called bismuth, and it's currently used to make products ranging from shotgun pellets to ...

Technique doubles conversion of CO2 to plastic component

24-May-2018

Fossil fuels have long been the precursor to plastic, but new research from the University of Nebraska-Lincoln and European collaborators could help send that era up in smoke - carbon dioxide, to be exact. Produced almost entirely from burning fossil fuels, carbon dioxide concentrations in the ...
