A two-step process for making graphene

A Korean team has developed a carbon material that is as effective as graphene in applications, such as solar cells and semiconductor chips, using a process that requires only two steps instead of the usual eight. High-quality graphene is usually…

A sorbent that enhances the water-gas shift reaction

Scientists at the National Energy Technology Laboratory (NETL; Morgantown, W. Va.; www.netl.doe.gov) have demonstrated a process for enhancing the efficiency of the water-gas shift (WGS) reaction. The process revolves around a magnesium hydroxide sorbent material that can remove CO2 from…

A new slurry pump that handles high volumes

The new Wirth triplex double-acting piston diaphragm (TDPM) pump combines two well established and proven pumping principles for the transport of high volumes of abrasive slurry. The Wirth TDPM works on the triplex double-acting principle. It has flowrates of up…

This recirculation pump doesn’t need external cooling

Early this month, this company launched a new generation of hot-water recirculation pumps for large industrial heating systems as well as forced-circulation boilers and district heating systems. The horizontal, radially split single-stage volute casing pumps feature a back pull-out design.…

This blower is now even more energy efficient

The E-Blower extends the high-efficiency solution provided by the company’s Delta Hybrid series in the low volume flow range. The new E-Design delivers a reduction of power demand of up to 4%, depending on volume flow and pressure difference, says…

Platform for reactive monomers enables short cure times for coatings

The potential usefulness of 1,1-di-substituted alkenes for making performance polymers has been recognized for some time, but commercialization has been elusive because of the reactive nature of the monomers. Startup company Sirrus Inc. (Loveland, Ohio; www.sirruschemistry.com) has developed technology to…

An improved PHA-bioplastic process is scaled up

A less expensive process for producing biodegradeable polyhydroxyalkanoate (PHA) plastics from renewable feedstocks is being scaled up by a factor of six, resulting in a 30,000–60,000-lb/mo pilot facility. The improved PHA process — developed by Meredian Inc. (Bainbridge, Ga.; www.meredianpha.com)…

A new route to a cellulose-based bioplastic

NEC Corp. (Tokyo, Japan; www.nec.com) has developed a two-stage, heterogeneous synthesis for making a high-functionality bioplastic (70 wt.% plant content) from non-edible plant cellulose. The new bioplastic is said to have excellent thermo-plasticity (275 MFR), heat resistance (140°C glass transition…
