This additive reverses the effects of aging in recycled asphalt pavement

A new rejuvenator technology aims to improve the chemistry and service life of recycled asphalt pavement (RAP). The Invigorate additive, developed by Colorbiotics (Ames, Iowa; www.colorbiotics.com) based on Iowa State University research (www.iastate.edu), helps overcome issues with asphaltene aggregation and…

Sustainable graphite pilot project kicks off in Canada

A new project in Canada will build a pilot facility to demonstrate a carbon-neutral production strategy for battery-grade graphite materials. Nouveau Monde Graphite (Saint-Michel-des-Saints, Québec, Canada; www.nouveaumonde.ca) has signed an agreement with Olin Corp. (Clayton, Mo.; www.olin.com) to construct two…

DESALINATION The challenge for large-scale desalination is to improve the performance of membranes used for reverse osmosis. One promising method is to introduce artificial water channels (AWCs) into synthetic membranes, to imitate the aquaporins of biological proteins for transporting water.…

Endress+Hauser establishes internet security standards

The cryptography working group within the Internet Engineering Task Force (IETF; Fremont, Calif.; www.ieft.org) standards organization has chosen the CPace protocol — developed by Endress + Hauser AG (Reinach, Switzerland; www.endress.com) — as a recommended method for use in internet…

Graphene-oxide filtration membrane for harsh chemical environments

Filtration is being investigated as an alternative to thermal separation methods (such as distillation and evaporation) in many applications because of the potential energy savings, but conventional filtration membranes, such as those used in water desalination, are often not robust…

Nanoengineered catalysts can upcycle polyethylene

Drawing inspiration from the enzymatic breakdown of macromolecules in cellular systems, scientists at Ames Laboratory (Ames, Iowa; www.ameslab.gov) have developed a nanostructured catalyst that can break down high-density polyethylene (HDPE) and other polyolefins into a narrow distribution of diesel- and…

This nanoengineered catalyst converts mixed, impure waste to biodiesel

In an example of a biologically inspired and nano-engineered catalyst, researchers at RMIT University (Melbourne, Australia; www.rmit.edu.au) have developed ceramic catalyst particles with a porous network organized hierarchically, where one chemical reaction takes place within larger pores, while a second…

First full integration of hydrogen production, distribution, storage and use is underway

The recently launched H2@Scale project is integrating a number of elements necessary for the commercial-scale integrated production and use of renewable hydrogen. Hosted by the University of Texas at Austin (www.utexas.edu) and funded through the Energy Efficiency and Renewable Energy…

Ethylene Last month, Linde GmbH (Pullach, Germany; www.linde.com) and Shell (den Hague, the Netherlands; www.shell.com) announced an exclusive collaboration agreement on ethane-oxidative dehydrogenation (E-ODH) technology for ethylene production. The catalytic process is an alternative route to ethane steam cracking, offering…

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…
