There are many categories of air contaminants that may be encountered in industry, from volatile organic compounds to aerosols to viruses, as well as a range of particulate matter and ultra-fine particles, which also vary greatly in size and properties.…
Recycling rates for post-consumer textile waste are very low (<0.5%) because the fabrics often consist of tightly interlaced synthetic and natural fibers that require costly sorting and separation processes, and because they often contain dyes and additives that must be…
Plasma technology is being explored as an avenue for many molecular conversions, such as methane reforming. Now, for the first time, a plasma-based CO2-conversion technology is being demonstrated industrially. The proprietary technology, developed by D-CRBN (Antwerp, Belgium; www.d-crbn.com), is being…
Co-fermentation processes that can consume both sugars and CO2 are emerging as a promising technology to enhance product yield and reduce emissions in biofuels production. A team of scientists at Oklahoma State University (Stillwater, Okla.; www.okstate.edu) are working to accelerate…
Artificial intelligence techniques have great potential in generating insights into catalytic reaction mechanisms, opening the door to more selective and efficient catalysts. However, using machine-learning (ML) in a general way to study chemical reactions is challenging because broad approaches aimed…
Using halide perovskites for photovoltaic (PV) solar-energy cells could dramatically reduce production costs compared to silicon-based PV cells, because perovskites are solution-processible at relatively low temperatures. However, long-term stability of these materials has been a significant challenge. Now, a research…
Electrolyzers are the key technology for producing “green” hydrogen using renewable energy. However, a new reactor platform aims to facilitate electrolysis without the need for any external electricity. The Electroless Coupled Exchange Reduction Oxidation technology platform (eXERO), developed by Utility…
Methane pyrolysis catalyst Catalytic methane pyrolysis (CMP) is an attractive route to producing hydrogen, because rather than generating CO2, the process produces solid carbon, which can be made in valuable forms that could offset the cost of hydrogen production. However,…
The prevalence of the various per- and polyfluoroalkyl substances (PFAS) — compounds that are notoriously difficult to break down — in the water supply is causing global concern. A new partnership between Element Six (Oxford, U.K.; www.e6.com) and Lummus Technology…
A research team at the University of Virginia School of Engineering and Applied Science (Charlottesville, Va.; engineering.virginia.edu) is the first to explore how an emerging plant-based material, cellulose nanofibrils, could amplify the benefits of 3D-printed concrete technology. “The improvements we…
