Researchers from Washington State University and Ohio State University have developed a low-cost, easy way to make custom lenses that could help manufacturers avoid the expensive molds required for optical manufacturing.
New technologies have made the world smaller. Rana Abudayyeh, a professor of interior architecture, asks how architects respond to shifting perspectives of space for displaced people. 'A Syrian refugee living in a Jordanian camp, or an immigrant to the US, will have multiple associations with place,' said Abudayyeh. 'They carry archival images of their home with them on smart devices, and that will influence the way they interact with their physical space.'
Producing cement takes a big toll on our climate: Around eight per cent of annual global carbon dioxide emissions can be attributed to this process. However, the demand for cement continues to rise. A team of geoscientists from Martin Luther University Halle-Wittenberg (MLU) has found a way to produce more environmentally friendly and sustainable alternatives. In the journal "Construction and Building Materials" they describe how industrial residues can be used to produce high-quality, climate-friendly materials.
A seemingly counterintuitive approach -- converting one greenhouse gas into another -- holds promise for returning the atmosphere to pre-industrial concentrations of methane, a powerful driver of global warming.
EPFL chemical engineers have designed an easy method to achieve commercially attractive carbon-capturing with metal-organic frameworks.
Researchers have developed a new method of using rare and expensive catalysts as sparingly as possible. They enclosed a precious metal salt in outer shells, tiny micelles, and had them strike against a carbon electrode, thus coating the surface with nanoparticles of the precious metal contained in the micelles. At the same time, the team was able to precisely analyse how much of the metal was deposited.
A research group led by Professor Liu Shengzhong from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences and Dr. XU Zhuo at Shaanxi Normal University (SNNU) developed a technique to prepare large size 2D perovskite single crystals to achieve highest photodetector performance among this type.
Unlike water, liquid refrigerants and other fluids that have a low surface tension tend to spread quickly into a sheet when they come into contact with a surface. But for many industrial process it would be better if the fluids formed droplets, which could roll or fall off the surface and carry heat away with them. Now, researchers at MIT have made significant progress in promoting droplet formation and shedding in such fluids.
A team of scientists has created a bowl-shaped electrode with 'hot edges' which can efficiently convert CO2 from gas into carbon based fuels and chemicals, helping combat the climate change threat posed by atmospheric carbon dioxide.
The production of 1-butene via ethylene dimerization is one of the few industrial processes that employs homogeneous catalysis due to their high selectivity. Now, a new paper by the University of the Basque Country (UPV/EHU), in collaboration with the Institute of Chemical Research of Catalonia (ICIQ) and RTI International, shows a more sustainable alternative.
