Chemical engineers from the Swiss Federal Institute of Technology Lausanne (EPFL; www.epfl.ch), in collaboration with scientists from Toyota Motor Europe (Zaventem, Belgium; www.toyota-europe.com), have invented a photoelectrochemical (PEC) “artificial leaf” that splits water vapor into H2. The technology features a…
For the first time, a quantum-computing-inspired tool has been used for catalyst discovery — specifically for the investigation of a new catalyst for the production of hydrogen via electrolysis. Created jointly by scientists from Fujitsu Ltd. (Tokyo; www.fujitsu.com) and the…
Blue Planet Systems (Los Gatos, Calif.; www.blueplanetsystems.com) and Sulzer Chemtech Ltd. (Winterthur, Switzerland; www.sulzer.com) have announced a partnership to accelerate development of Blue Planet’s process for mineralizing carbon dioxide gas into construction aggregate for concrete. By sequestering CO2 into the…
Production of ammonia by the Haber-Bosch process not only requires a lot of energy for the high-temperature (300–500°C) synthesis of NH3 itself, but the recovery of ammonia takes place by condensation at –20°C. As a result, large changes in both…
Japan’s National Institute for Materials Science (NIMS; Ibaraki, Japan; www.nims.go.jp), along with Harvard University (Cambridge, Mass.; www.harvard.edu) and the University of Connecticut (Storrs, Conn.; www.uconn.edu), have designed a new imaging device that uses structural colors — visible colors that change…
Isosorbide is a glucose-derived, rigid, secondary diol monomer that can impart favorable mechanical, barrier and thermal properties to condensation polymers, such as polyesters. However, for the past two decades, it has not been possible to synthesize fully bio-based poly (isosorbide…
Developed by researchers at the Massachusetts Institute of Technology (MIT; Cambridge, Mass.; www.mit.edu), these durable, flexible solar cells are glued to a strong, lightweight fabric, making them easy to install on a fixed surface. They are one-hundredth the weight of…
BTX extraction A newly launched series of blended solvents for the extraction of benzene, toluene and xylenes (BTX) from a variety of feeds shows improved performance over single solvents, while avoiding environmentally problematic solvent components. The series, known as BTX…
Bauxite residue (red mud) is a byproduct from the smelting of aluminum. Like other waste slags from the metallurgy industry, bauxite residue is traditionally put into hazardous-waste landfills, although it contains a mixture of valuable raw materials in low concentrations.…
Granular activated carbon (GAC) can be used to remove polyfluoroalkyl substances (PFAS) from groundwater and drinking water, but current methods to regenerate spent GAC are costly and require high temperatures of greater than 1,000°C. A team of scientists at Battelle…
