Ammonia synthesis by mechanocatalysis in a ball mill
A breakthrough in the fight against hunger, three Nobel Prizes, and 150 million tonnes of annual production—yet still a tricky topic for research: For over 100 years, the chemical industry has been using the Haber-Bosch process to convert atmospher.....»»
New synthesis process paves way for more efficient lasers, LEDs
Researchers from North Carolina State University have developed a new process that makes use of existing industry standard techniques for making III-nitride semiconductor materials, but results in layered materials that will make LEDs and lasers more.....»»
Facet controllable synthesis of two-dimensional rare earth oxides
Since graphene was awarded the Nobel Prize in 2010, two-dimensional (2D) materials have continued to attract researchers' attention in logic, storage, optoelectronic and photonic 2D device manufacturing fields because of the atomic thickness and exce.....»»
Agricultural runoff contributes to global warming, but a new study offers insight on climate-change mitigation
Nitrous oxide (N2O) is a potent greenhouse gas, with 300 times the warming ability of carbon dioxide. Due to fertilizer runoff from farm fields, an increasing load of nitrogen is washing into rivers and streams, where nitrogen-breathing microbes brea.....»»
Shagene A synthesis perfected for leishmaniasis treatment
Just north of Antarctica and a little east of the southern tip of South America is the Scotia Sea. Besides glimpses of an occasional iceberg, these waters offer little to tourists......»»
Imaging technique reveals strains and defects in vanadium oxide
Researchers led by Edwin Fohtung, an associate professor of materials science and engineering at Rensselaer Polytechnic Institute, have developed a new technique for revealing defects in nanostructured vanadium oxide, a widely used transition metal w.....»»
Photoinitiators for dental fillings, contact lenses and dentures
Photoinitiators ensure that liquid plastic—for example for dental fillings—hardens quickly by means of light. Thanks to a new synthesis method developed by TU Graz, these initiators can be produced cheaply, something which will open up further do.....»»
Binary stars boost cosmic carbon footprint
The cosmic origin of carbon, a fundamental building block of life, is still uncertain. Massive stars play an important role in the synthesis of all heavy elements, from carbon and oxygen to iron and so on. But even though most massive stars are born.....»»
Total synthesis of the sesquiterpene agarozizanol B
Starting from available chemicals, a German team of researchers successfully completed the total synthesis of agarozizanol B, an interesting natural substance found in agarwood. As described in the journal Angewandte Chemie, the key sequence in the r.....»»
New strategy achieves efficient and stable carbon dioxide electrolysis in solid oxide electrolysis cell
Solid oxide electrolysis cell (SOEC) is promising in CO2 conversion and renewable clean electricity energy storage. It can convert CO2 and H2O simultaneously into syngas or hydrocarbon fuel at the cathode, and produce high purity O2 at the anode......»»
Manganese makes its mark in drug synthesis
Just because you've solved a standing chemistry challenge doesn't mean you can't make it better. Rice University scientists had that in mind when they set out to improve their technique to make a common building block for drugs......»»
Correlated electrons "tango" in a perovskite oxide at the extreme quantum limit
A team led by the Department of Energy's Oak Ridge National Laboratory has found a rare quantum material in which electrons move in coordinated ways, essentially "dancing." Straining the material creates an electronic band structure that sets the sta.....»»
