Biogas from brewery wastewater makes power with a fuel cell
This month, a demonstration project to generate power from fuel cells running on biogas has begun at Asahi Breweries’ Ibaraki Brewery. Coordinated by Asahi Quality & Innovations, Ltd., an independent research subsidiary of Asahi Group Holdings, Ltd. (Tokyo, Japan; www.asahigroup-holdings.com),…
Fruit peels help recover metals from e-waste
Scientists from Nanyang Technological University (NTU; Singapore; www.ntu.edu.sg), led by professor Madhavi Srinivasan, have developed a method of using orange peel waste to extract precious metals from spent lithium-ion batteries and to make batteries from those recovered metals, creating minimal…
Graphene-POSS polymer additives enable lightweighting
MITO Material Solutions (Indianapolis, Ind.; www.mitomaterials.com) has developed a proprietary graphene-functionalization technique that produces unique strength-enhancing additives for a wide variety of polymers and composites. The additives significantly improve mechanical properties (including tensile strength, flexural modulus and others) of the…
Single-atom thin platinum makes a sensitive chemical sensor
Boosting the sensitivity of solid-state gas sensors is often achieved by incorporating nanostructured materials as the sensing element. However, interfacial effects at nanoparticles, grains or contacts can lead to non-linear responses, high electrical resistance or electrical noise. A possible way…
An electrochemical process treats wastewater from biofuels production
Researchers from the School of Chemical and Biomolecular Engineering at the Universiy of Sydney (Sydney, Australia; www.sydney.edu.au), led by Alejandro Montoya, have developed an electrochemical oxidation process to clear up wastewater, which is heavily contaminated with organic and inorganic species…
New fabrication method for fluorine-containing carbon-capture membranes
Recent work by a team of researchers from Oak Ridge National Laboratory (ORNL; Oak Ridge, Tenn.; www.ornl.gov) and the University of Tennessee (Knoxville; www.utk.edu) has brought cost-effective, fluorinated carbon molecular-sieve membranes within closer reach. To make the membrane, the researchers…
A zinc-based catalyst makes syngas by co-electrolysis
Researchers from the University of New South Wales (Sydney, Australia; www.unsw.edu.au), led by professor Rose Amal, have shown that by making zinc oxide at very high temperatures using a technique called flame spray pyrolysis (FSP), they can create nanoparticles that…
Waste-based rubber can be joined or repaired catalytically
A new sustainable rubber that can, with an amine catalyst, be repaired and returned to its original strength in minutes, has been discovered by researchers from Flinders University (Adelaide, Australia; www.flinders.edu.au), the University of Western Australia (Perth), and the University…
Improved process for treating AMD waste recovers more rare earth elements
By modifying a traditional treatment method for acid mine drainage (AMD), researchers at Penn State University (PSU; State College, Pa.; www.psu.edu) were able to both reduce the amount of chemicals required for treatment and increase the amount of rare earth…
A new approach makes flexible screw pumps
Leistritz Pumpen GmbH (Nuremberg, Germany; www.leistritz.com) has recently introduced Flexcore, the first screw pump capable of adapting to a wide range of installation situations. “With Flexcore, Leistritz has now created a globally groundbreaking innovation — a pump class that, for…
