Hot CO2 separation

Researchers from the Center for Synthesis and Chemical Biology (CSCB; Dublin; edlinks.chemengonline.com/6518-551) have developed an ultrathin, nanoporous membrane that can separate carbon dioxide from nitrogen at 600°C; up to now, no membranes have been available to separate CO2 at temperatures…

Bioethanol

Over the last three years, DuPont (Wilmington, Del.; edlinks.chemengonline.com/6518-552) has been developing technology to break down the complex sugar matrix of corn stover as a means for making ethanol from cellulose in high yield. Although there is more research to…

Biopharm purification

GE Healthcare (Chalfont St. Giles, U.K.; edlinks.chemengonline.com/6518-554) and BAC B.V. (Naarden, Netherlands; edlinks.chemengonline.com/6518-555) are collaborating to develop new affinity-ligand and chromatography media for human antibodies and adeno-associated virus (AAV) viral vector purification. The first products are expected to be commercially…

Level measurement highlights

      Among the many parameters measured and controlled in the chemical process industries (CPI), level definitely ranks high in importance, and in some applications, can even be critical. Accurate level measurements commonly guide decision makers in inventory and…

Last month, the American Chemical Society (ACS) celebrated its 19th annual National Chemistry Week, a community-based program that aims to communicate how chemistry benefits quality of life. The initiative goes hand-in-hand with the American Chemistry Council’s (ACC’s) “essential2” advertising campaign,…

The Do’s and Don’ts Of Chute Design

    The need to transfer bulk-solids materials from the outlet of a bin or from a conveyor, to a process, truck, or another bin is ubiquitous throughout the chemical process industries (CPI). Transferring material using equipment designed to mechanically…

Perchlorate

Scientists from the University of Illinois at Urbana-Champaign (edlinks.chemengonline.com/6517-551) have developed a catalyst that uses hydrogen to efficiently destroy harmful perchlorate in contaminated groundwater. The catalyst is composed of palladium and rhenium supported on activated carbon. The rhenium removes an…

Poplar’s code  

Researchers from 34 institutions from around the world have completed the first DNA sequence for a tree, the black cottonwood or Populus trichocarpa (poplar). This poplar's rapid growth and relatively compact genome size (480 million nucleotide units, or 1/40th as…
