Titanium dioxide is well known as a photocatalyst, and is especially promising for degrading organic-based contaminant molecules in wastewater. Researchers from China and Australia have reported, in a recent issue of the Journal of Colloid and Interface Science, that controlling…
A new technique for making less-expensive, more-efficient biological enzyme hybrids could have widespread applications, including in water recycling, drug manufacturing and molecular biology. The technique, developed by a team from Australia and the U.S., involves using a vortex fluidic device…
A Korean team has proposed an approach for passive radiative cooling. The team, which includes professors Junsuk Rho and Jin Kon Kim of Pohang Universiy of Science and Technology (Pohang, South Korea; www.postech.ac.kr) and professor Heon Lee of Korea University…
A process developed by Evrnu (Seattle, Wash.; www.evrnu.com) to regenerate cotton fibers from waste fabric and post-consumer garments has been used to produce ton quantities of recycled cotton fiber for testing. An economically viable process for recycling cotton would have…
A new membrane technology for separating carbon dioxide from exhaust gas will be scaled up for real-world testing under a project to evaluate low-cost CO2 capture at a coal-fired power plant. Design and testing of an engineering-scale CO2-capture system will…
Late last November, the energy-transition start-up company Lumenion GmbH (Berlin, Germany; www.lumenion.com) received the 2020 Berlin Brandenburg Innovation Prize for its high-temperature, steel-based energy-storage technology. The system stores peaks of wind and solar energy by heating a steel core to…
Researchers from the College of Chemical Engineering, Nanjing Tech University (Nanjing, China; www.njtech.edu.cn) have developed a new strategy for forming lithium ion-sieve membranes to achieve an efficient recovery of lithium ions from brine or seawater. Spinel lithium manganese oxide ion-sieves…
Site commissioning is underway at a facility in Nebraska that uses plasma pyrolysis to generate hydrogen gas and carbon black from natural gas without any local carbon dioxide emissions. The developer, Monolith Materials (Lincoln, Neb.; www.monolithmaterials.com), scaled up the process…
A new rejuvenator technology aims to improve the chemistry and service life of recycled asphalt pavement (RAP). The Invigorate additive, developed by Colorbiotics (Ames, Iowa; www.colorbiotics.com) based on Iowa State University research (www.iastate.edu), helps overcome issues with asphaltene aggregation and…
A new project in Canada will build a pilot facility to demonstrate a carbon-neutral production strategy for battery-grade graphite materials. Nouveau Monde Graphite (Saint-Michel-des-Saints, Québec, Canada; www.nouveaumonde.ca) has signed an agreement with Olin Corp. (Clayton, Mo.; www.olin.com) to construct two…
