Enhanced perovskites
Researchers from the Ulsan National Institute of Science and Technology (Ulsan; www.unist.ac.kr) have found a new way to increase the energy efficiency of metal-air batteries — which are next-generation energy devices — by adding the conducting polymer polypyrrole (pPy). According…
Harvesting agricultural fertilizers from wastewater sludge
Recovery of the essential plant nutrient phosphorus from wastewater can be an effective way to reduce runoff into waterways while avoiding the need to obtain the element from mined minerals. While phosphorus recovery from wastewater effluent performs well, it is…
Scaleup for cellulose nanofiber production
Nippon Paper Industries Co. (NPI; Tokyo, Japan; www.nipponpapergroup.com) has installed the world’s largest facility of its kind for the commercial production of cellulose nanofiber (CNF). Located at its Ishinomaki Works in Miyagi Prefecture, the $16-million investment has a production capacity…
Low-cost solar collectors provide renewable process heat
The first pre-commercial demonstration has started for a system that can provide steam for industrial process heat using solar energy at prices lower than using natural gas. The technology uses solar thermal collectors to generate hot water, air or steam…
Silk-based batteries for medical implants
Researchers from the University of Wollongong (Australia; www.uow.edu.au), led by professor Gordon Wallace and Caiyun Wang, built a battery with electrodes and a solid electrolyte out of silk. Previous attempts at making such biodegradable, dissolvable batteries used natural, biocompatible materials…
Nanorod arrays as photocatalysts
Many ZnO@TiO2 core-shell nanorod arrays (the notation means ZnO is the core inside the TiO2 shell) with good photocatalytic activity have been designed and synthesized. There has been an increasing interest in the design and synthesis of those arrays to…
Plasma oxidation for making carbon fibers
Carbon fibers, an increasingly essential component for lightweight materials, are typically made from polyacrylonitrile (PAN) in a three-step process consisting of oxidation/stabilization, carbonization and surface treatment/sizing. 4M Industrial Oxidation, LLC (Knoxville, Tenn.; www.4mio.com) intends to commercialize a technology to produce…
Novel approach to Si-metal anodes could lower Li-ion battery cost
A new approach to making silicon-based anodes for lithium-ion batteries has the potential to lower materials costs for batteries, while achieving higher energy and power. Silicon-based anodes are attractive because of silicon’s natural abundance and its high specific capacity, but…
Piloting of a ‘revolutionary’ approach to olefin cracking
Earlier this year, Coolbrook Oy (Helsinki, Finland; www.coolbrook.fi) received a €3.6-million grant from the Finnish Funding Agency for Innovation Tekes to further develop its patented RotoDynamicReactor (RDR) technology, which has the potential to improve ethylene yields by 34% compared to…
Chementator Briefs
FCC catalyst BASF SE (Ludwigshafen, Germany; www.basf.com) recently launched Borotec, the newest evolution of its resid-oil fluid-catalytic-cracking (FCC) catalysts portfolio. Borotec is the latest innovation using BASF’s unique Boron-Based Technology (BBT) platform to provide mild- and moderate-resid-feed FCC units more…
