AkzoNobel N.V. (www.akzonobel.com) has partnered with Dutch start-up company Photanol (both Amsterdam, the Netherlands; www.photanol.com) to manufacture specialty chemicals using a photosynthesis-like process that combines sugar production with fermentation in a single organism. Photanol has developed genetically engineered cyanobacteria that…
A method for using liquid CO2, rather than water, as a hydraulic fracturing fluid has been field-tested in a mid-continent oil well, and has benefited well productivity, according to developer Praxair Inc. (Danbury, Conn.; www.praxair.com). Aside from enhanced well performance,…
Last month, Veolia Water Technologies (Birmingham, England; www.veoliawaterst.co.uk) introduced a new generation of biofilm carriers for moving-bed biofilm reactors (MBBRs). Trade-named AnoxKaldness Z-MBBR, the new carrier is the result of two decades of development work, says the company. Unlike conventional…
The research group of Masatsugu Morimitsu at Doshisha University (Kyoto, Japan; www.doshisha.ac.jp) has developed an “evolutionary” electrowinning process for the production of rare and base metals that promises to reduce both the power consumption and environmental burden. The process features…
Graphene continues to show new, promising properties Researchers from Monash University (Melbourne, Australia; www.monash.edu.au) have discovered that graphene oxide sheets can change their structure and become liquid droplets spontaneously. Because graphene droplets change their structure in response to an…
Last month, NET Power, LLC (Durham, N.C.; www.net-power.com) announced the completion of major project agreements for its first-of-a-kind power plant — a 50-MWth demonstration plant that will validate the world’s first natural-gas power generation system that produces no air emissions,…
Last month, the first commercial-scale, post-combustion carbon capture and storage (CCS) plant started up in Saskatchewan, Canada. The SaskPower facility at the Boundary Dam Power Station is expected to capture around 1 million m.t./yr of CO2, which is up to…
Scientists from the Materials Science and Technology Div. of the U.S. Naval Research Laboratory (Washington, D.C.; www.nrl.navy.mil) have developed a one-step process to form oxide nanoparticles. The technique is capable of producing large quantities (10 g) of oxide nanoparticles —…
Researchers from Monash University (Melbourne, Australia; www.monash.edu.au) have discovered that graphene-oxide sheets can change their structure and become liquid droplets spontaneously. Because graphene droplets change their structure in response to an applied magnetic field, they could be used for controlled…
Aiming to understand the nature of the synergistic effect of ultrasound and enzymes in the production of fermentable sugars from lignocellulosic biomass, researchers from the Institute of Chemical Technology (Mumbai, India; www.ictmumbai.edu.in) have studied the ultrasound-assisted enzymatic hydrolysis of waste…
