Water treatment The recently introduced FoodPro ST line of water-treatment chemicals from GE Power & Water (Trevose, Pa.; www.ge.com) prevents corrosion and scale in stainless-steel sterilizers and pasteurizers in the food and beverage industry, and they are less expensive than…
Microbial processing of ore
Extraction of metals, such as lithium, from laterite ores is usually carried out through solubilization of metals by acids, such as sulfuric and hydrochloric acids. However, substantial metal recoveries from laterites have been achieved only through thermal pre-treatment of laterites,…
Catalytic ethane-cracking process allows lower-temperature operation
Aither Chemicals LLC (South Charleston, W.Va.; www.aitherchemicals.com) is planning to build a commercial-scale plant based on a catalytic ethane-cracking process that uses 80% less energy and generates 60% less carbon dioxide than conventional steam-cracking of ethane. The company has refined…
This fully functional Li-ion battery is flexible
A team from the Korea Advanced Institute of Science and Technology (Kaist; Daejeon, South Korea: www.kaist.ac.kr) and Seoul National University (www.useoul.edu) led by Kaist’s professor Keon Jae Lee, claims to have developed the first prototype of a fully functional all-flexible…
A nano cage made from a stack of benzenes
Professor Kenichoro Itami and his group at Nagoya University (synth.chem. nagoya-u.ac.jp) have synthesized a cage-type carbon nano-molecule, Carbon Nano-cage, composed of 20 condensed benzene rings — C120H78. The group used a procedure it developed four years ago to synthesize carbon…
A polymersome that releases its cargo where needed
Several drug delivery systems have been studied involving the encapsulation of molecules in a suitable structure and their transport through the human body. In particular, polymersomes — tiny hollow spheres that enclose a solution — formed using synthetic block copolymers…
October Chementator Briefs
Flexible aerogels Researchers at the NASA Glenn Research Center (Cleveland, Ohio; www.nasa.gov) have developed new flexible aerogels that could eventually be used in highly insulating materials and linings. Aerogels, sometimes called “solid smoke,” are superlightweight structures of silica reinforced…
A cryogenic turbo mill generates rubber powder from recycled tires
A process developed by Lehigh Technologies (Lehigh; Tucker, Ga.; www.lehightechnologies.com) for embrittling and milling rubber from end-of-life vehicle-tire material is capable of generating micron-scale rubber particles that can be used in a host of rubber, foam and plastic products to…
A concept for making gasoline from air
Air Fuel Synthesis Ltd. (AFS; Darlington, U.K.; www.airfuelsynthesis.com) has recently demonstrated a process for producing carbon-neutral liquid hydrocarbon (HC) fuel from air-captured carbon dioxide and hydrogen. The proof-of-concept demonstration facility, located at Teesside, England produces 5–10 L/d of liquid HCs.…
Progress for making smart membranes
Last month marked the completion of the three-year, €3.6-million E.U.-funded research project, Self-assembled Polymer Membranes (SelfMem). Coordinated by the Institute of Polymer Research at the Helmholtz-Zentrum Geesthacht (HZG; Germany; www.hzg.de), with twelve partners from industry and academia in Israel, Canada…
