A fast-acting, durable self-disinfecting polymer

A patented polymer material developed by Kraton Corp. (Houston; www.kraton.com) has shown rapid antimicrobial capabilities with expected long-lasting self-disinfecting efficacy. Currently pursuing regulatory review in the U.S. and other select countries for use as an antimicrobial agent, Biaxam is a…

A microwave-plasma process that efficiently makes hydrogen and acetylene

A new modular process based on microwave-plasma reactors aims to efficiently convert natural gas into acetylene and H2 without combustion or CO2 formation. Transform Materials LLC (Riviera Beach, Fla.; www.transformmaterials.com) has designed a reactor that overcomes some of the previous…

A more efficient way to upgrade lignin bio-oils

Lignin bio-oil is a common waste stream formed during the production of cellulose and ethanol from biomass. Due to its high oxygen and low hydrogen content, lignin bio-oil must be upgraded via hydrogenation and deoxygenation before it can be used…

New process efficiently filters hormones from water

Drinking water can be contaminated with micropollutants, including steroid hormones that are used as medical substances and contraceptives. Although their concentration in wastewater may be only a few nanograms per liter, this small amount can already damage human health and…

Increasing energy density in capacitors

Capacitors are attractive in large-scale energy-storage applications, such as electric vehicles or grid storage, because of their ability to rapidly charge and discharge, but their energy densities have been too small to allow their use in such applications. Researchers at…

Chementator Briefs

Ethylene dichloride Recently, Chemetry (Moss Landing, Calif.; www.chemetrycorp.com) and Braskem (Sao Paulo, Brazil; www.braskem.com) announced their intent to construct and operate a demonstration plant using Chemetry’s eShuttle technology for the production of ethylene dichloride (EDC) in Brazil. The initial focus…

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…
