Generalizable deep-learning technique for elucidating catalyst reaction mechanisms
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…
Two-dimensional template increases stability of perovskite photovoltaics
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…
This electrolysis reactor requires no external electricity source
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,…
This integrated technology effectively destroys PFAS — even short-chain compounds
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…
