Chiral light-matter interactions have been investigated for two centuries, leading to the discovery of many chiroptical processes used for discrimination of enantiomers. Whereas most chiroptical effects result from a response of bound electrons, photoionization can produce much stronger chiral signals that manifest as asymmetries in the angular distribution of the photoelectrons along the light-propagation axis. We implemented self-referenced attosecond photoelectron interferometry to measure th...

The Environmental Protection Agency (EPA) has with immediate effect ordered the repatriation of four 40-feet containers of hazardous chemicals to Greece, from where they were brought, before entering Liberia. According to EPA Executive Director Nathaniel Blama, the chemical on the containers were fast tracked by the Liberia Revenue Authority (LRA) while conducting its regular inspection of cargos that are brought into the country. The EPA Director said the chemical when disposed of in any ...

The carbon footprint in the chemical industry is likely to reduce as engineers from Rice University have invented a light-powered nanoparticle to help the cause. They are tiny spheres of copper dotted with single atoms of ruthenium, is the prime ingredient in composing a green process for developing synthesis gas, commonly known as syngas, the valuable chemical feedstock generally used to make fertilizer, fuels, and many other products. Researchers from Rice, UCLA and the University of Californi...

Shell has recently announced it has signed a Memorandum of Understanding with CNOOC Oil & Petrochemicals Co. Ltd to explore its first commercial-scale polycarbonate (PC) production unit, which would be located at the CNOOC and Shell Petrochemical Co. (CSPC) joint-venture chemicals complex in Huizhou, China. As an interim step, Shell has started constructing a PC development unit at its Jurong Island chemicals plant in Singapore. An expanded and differentiated product range is a key part of S...
