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…

Chementator Briefs

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…

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 novel, structural, carbon-negative cement

Magnesia cements have been around for thousands of years, and have been explored extensively over recent decades primarily because of their capacity to absorb CO2 from the atmosphere at ambient temperatures. Until now, however, their use has been limited to…

Nanoparticles improve lubricant performance in friction and wear prevention

Nanoscale materials have been added to engine lubricants to enhance performance for some time, but the use of such materials has been limited by their inability to remain suspended in the oils, and by their tendency to darken the color…
