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…

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.…

New catalysts for Baeyer-Villiger oxidation reactions

Kazuaki Ishihara and his group at Nagoya University (Japan; www.ishihara-lab.net) have established a new, environment friendly reaction technology — using Baeyer-Villiger oxidations — for selectively oxidizing ketones into esters. The reaction uses hydrogen peroxide as the oxidant, and has potential…
