Missing atoms in a forgotten crystal bring luminescence


A little-studied member of the perovskite family of materials could find use in a range of electronic devices, after researchers at KAUST discovered the secret of its strong photoluminescence. Perovskites are a wide group of materials that are known to have remarkable optical and electronic ...


Getting the most out of natural gas


The use of natural gas as a raw material for chemicals production is a goal pursued intensively in chemical research. Scientists working under Javier Pérez-Ramírez, Professor of Catalysis Engineering, have now succeeded in optimising a process which enables natural gas constituents to be upgraded ...

ORNL tracks how halogen atoms compete to grow 'winning' perovskites


Researchers at the Department of Energy's Oak Ridge National Laboratory have found a potential path to further improve solar cell efficiency by understanding the competition among halogen atoms during the synthesis of sunlight-absorbing crystals. Photovoltaic cells that convert sunlight directly ...

Smallest Swiss cross - Made of 20 single atoms


The manipulation of atoms has reached a new level: Together with teams from Finland and Japan, physicists from the University of Basel were able to place 20 single atoms on a fully insulated surface at room temperature to form the smallest "Swiss cross", thus taking a big step towards next ...


Do not get from the frying pan into the fire

Ceresana publishes new market report on flame retardants


Flame retardants prevent or delay the combustion of materials and are indispensable in the protection of plastic products, electric devices, construction materials or textiles. An increasing demand for plastics in the construction sector, automotive industry and the segment electrics and ...


New flow battery could enable cheaper energy storage

Design may support widespread use of solar and wind energy


MIT researchers have engineered a new rechargeable flow battery that doesn't rely on expensive membranes to generate and store electricity. The device, they say, may one day enable cheaper, large-scale energy storage. The palm-sized prototype generates three times as much power per square ...


Chemophobia shouldn't be on the menu

New Dartmouth study finds many people unnecessarily fear low amounts of chemicals in their food


When it comes to what's for dinner – or breakfast and lunch for that matter-- many people suffer from chemophobia, an irrational fear of natural and synthetic chemicals that pose no risk to our health, a Dartmouth study finds. Chemistry Professor Gordon Gribble, whose paper appears in the journal ...

Noble way to low-cost fuel cells, halogenated graphene may replace expensive platinum


The research team of Ulsan National Institute of Science and Technology (UNIST), Case Western Reserve University and University of North Texas have paved a new way for affordable commercialization of fuel cells with efficient metal-free electrocatalysts using edge-halogenated graphene ...


Metal-free catalyst outperforms platinum in fuel cell

Researchers now optimizing cheap, easy-to-make alternative


Researchers from South Korea, Case Western Reserve University and University of North Texas have discovered an inexpensive and easily produced catalyst that performs better than platinum in oxygen-reduction reactions. The finding, detailed in Nature's Scientific Reports, is a step toward ...
