Researchers at the City University of New York Energy Institute (ccny.cuny.edu) have developed a low-cost battery based on manganese dioxide and zinc that reaches voltages of greater than 2 V, a first-time achievement that could allow batteries with these low-cost…
On September 19, Focus-On (Dordrecht, the Netherlands; www.focus-on-process.com) — a new, 50:50 joint-venture (JV) of Samson AG (Frankfurt am Main; www.samson.de) and Krohne GmbH & Co. KG (Duisburg, both Germany; www.krohne.com) — introduced its new “intelligent process node,” a device…
Scientists at Nanyang Technological University (NTU; Singapore; www.ntu.edu.sg) have developed a device for atmospheric monitoring that can identify a wide range of airborne gases and chemicals instantly. The prototype device is portable and suitable for rapid deployment by agencies to…
Researchers at the University of South Florida (USF; Tampa, Fla.; www.usf.edu) have developed a microbial metabolic pathway that allows enzymatic conversion of one-carbon compounds into multi-carbon intermediate chemicals. The bioconversion process, which takes place in genetically engineered bacteria, could enable…
Removal of phosphorus and other nutrients from wastewater is critical to preventing harmful algal blooms in coastal waters. Enhanced biological phosphorus removal (EBPR) — which relies on microbial communities that consume phosphate, reducing its concentration in the wastewater — has…
Because of their large surface area per unit mass, nanoparticles of additives can have a big impact on the properties of plastics, such as changing the crystallization temperature, and improving heat transfer, electrical properties (conductivity) and mechanical properties, as well…
Linde Engineering (Pullach, Germany; www.linde-engineering.com) has developed a process to recover helium, hydrocarbons and purified carbon dioxide from natural gas, while conditioning the natural gas for pipeline transport by adjusting the water and heavy-hydrocarbon dew point and the CO2 concentration.…
A low-cost “green” technology for water desalination and zero liquid discharge of industrial wastewater that has been drawing increasing attention is solar steam generation using nanostructured photothermal materials. However, the crystallization of salts on the surface of photothermal materials during…
Carbyne transfer Marcos G. Suero and his research group at the Institute of Chemical Research of Catalonia (ICIQ; Tarragona, Spain; www.iciq.es) have reported a new reaction that inserts a monovalent carbon unit between both sp2-hybridized carbons of alkenes. For the…
A process for in-situ oxidation of hydrocarbons in low-quality oilfields, and subsequent gas separation, offers a path to generating hydrogen for fuel and chemicals that avoids any greenhouse gas emissions. Known as Hygienic Earth Energy (HEE), the process has been…
