Catalytic process converts sorted waste into aromatic compounds
The rising cost of landfilling trash creates a strong incentive to utilize the waste for saleable products. A recently piloted process is an example: the process can convert municipal solid waste (MSW) into a narrow range of valuable aromatic compounds.…
Control biofouling with I2-vapor disinfection
A patented technology for infusing bubbles of elemental iodine into fluid or air can reduce microbial counts and potentially eliminate surface biofilms. Originally developed to remove biofilms from water lines in the dental industry, the technology is being used as…
This coating makes glass into a solar panel
A layered coating that acts as an organic semiconductor material allows building windows to generate electricity from direct, indirect, shaded, diffused and reflected sunlight, as well as from artificial light. Developer SolarWindow Technologies Inc. (Columbia, Md.; www.solarwindow.com) has designed and…
Environmentally safe oil-sands extraction
Processing oil sands is a mechanically intense process that involves pumping steam underground to emulsify crude petroleum. The procedure presents what MCW Energy Group (Toronto, Ont.; www.mcwenergygroup.com) CEO and former Exxon executive Jerry Bailey calls an “environmental nightmare.” Among the…
CO2 in biomass pre-treatment
Ionic liquids are being investigated as a way to break down cellulosic plant material in biofuels-production processes. A significant hurdle to their use is the fact that ionic liquids are toxic to the microbes used in biofuel production. Researchers from…
New process for cyclohexasilane offers lower cost and improved safety
A newly developed process for manufacturing cyclohexasilane (CHS; Si6H12) offers a lower-cost and safer pathway to a material whose molecular architecture allows a wider range of material possibilities than alternative starting materials for several important silicon-based products. CHS can be…
Recover chemicals from sugarcane bagasse using the half the energy
Last month, the New Energy and Industrial Technology Development Organization (NEDO; Kawasaki, Japan; www.nedo.go.jp) signed a Memorandum of Understanding (MOU) with the National Innovation Agency (NIA; Bangkok, Thailand; www.nai.or.th) to work jointly on a project to demonstrate a manufacturing system…
Chementator Briefs
Li-ion batteries Over the course of several battery charge/discharge cycles, microscopic fibers of lithium, called dendrites, sprout from the surface of the lithium electrode and spread across the electrolyte until they reach the other electrode. An electrical current passing through…
A smart adhesive that ‘turns on’ at body temperature
Scientists from the Korea Institute of Science and Technology (Seoul; www.kist.re.kr) and Ulsan National Institute of Science and Technology (UNIST; Ulsan, both Sout Korea; www.unist.ac.kr), led by UNIST’s professor Hyunhyub Ko, have developed smart adhesive pads — in the form…
Hybrid 3-D-printing process optimizes performance, cost for aerospace parts
Alcoa Inc. (Pittsburgh, Pa.; www.alcoa.com) has developed a hybrid technique, called Ampliforge (diagram), that combines additive manufacturing (3-D printing) and advanced forging techniques to improve the performance and reduce the cost of metal aerospace components. The company has produced prototype…
