Drive & Charge The R&D teams from Holcim Ltd. (Zug, Switzerland; www.holcim.com) and Magment GmbH (Oberhaching, Germany; www.magment.co) have developed a unique concrete with high magnetic permeability, which enables electric vehicles to recharge wirelessly while in motion. Known as inductive…
Decomposing limestone (CaCO3) into quicklime (burnt limestone; CaO) releases significant CO2 emissions, both from the combustion of fuel needed to heat the kiln to temperatures over 1,000°C, and by the release of CO2 from the reaction itself (CaCO3 → CaO…
Allyl chloride (3-chloropropene; Figure 1) is primarily used almost exclusively as a chemical intermediate in the production of epichlorohydrin. A three-carbon epoxide, epichlorohydrin is used in the manufacture of epoxy resins prevalent in coatings, adhesives, and plastics. Epichlorohydrin is also…
In order to maximize longevity and minimize process downtime, it is imperative to understand the factors that determine the proper selection of expansion joints. The following guidelines can help with selection decisions for expansion joints Although sometimes overlooked or treated…
Light hydrocarbons in storage tanks can vaporize and vent to the atmosphere, creating harmful emissions. An optimized vapor-recovery unit can effectively and economically reduce such emissions In the chemicals, petroleum refining and natural gas industries, storage vessels are used to…

Copper-catalyzed electrochemical reduction offers a path for making valuable chemicals, such as ethanol or ethylene, from CO2. However, selectively generating sufficient yields of two-carbon products requires precise manipulation of the microenvironment near the surface to control reaction activity and product…
The prospects for a bio-based route to acrylates (diagram) received a significant boost recently, when startup company Låkril Technologies Corp. (Chicago, Ill.; www.lakril.com) licensed technology from the laboratory of Paul Dauenhauer at the University of Minnesota (Minneapolis, Minn.; twin-cities.umn.edu). Dauenhauer…
