3D nanostructures
By combining a high-resolution scanning electron microscope and an ion-beam microscope into a single device, researchers at the Max Plank Institute for Iron Research (Düsseldorf, Germany; edlinks.chemengonline.com/5828-545) are able to “see” the inner structure of nanomaterials, biological matter, and high-performance…
Steam Handling
Sodium-ion monitoring can prevent steam-turbine corrosion Studies have shown that sodium is one of the most significant contributors to corrosion within turbines, and that such corrosion leads to cracking, embrittlement and ultimately, turbine failure. The Orion Ionplus 2111LL low-level sodium…
Chementator: An improved PC resin
PolymersNet Co. Ltd. (Seoul, South Korea; edlinks.chemengonline.com/5827-548) and Cyclics Corp. (Schenectady, N.Y.; edlinks.chemengonline.com/5827-549) announced the first commercial application of CBT (cyclic butylene terephthalate) resin as a modified polycarbonate (PC). PC is used for making compact disks and automobile components, but…
Chementator: Heterogeneous catalyst
A heterogeneous catalyst for producing the solvent methyl isobutyl ketone has been developed by graduate student Ferry Winter, who defended his chemistry Ph.D. thesis last month at Utrecht University (Netherlands; edlinks.chemengonline.com/5827-550). The catalyst is based on activated hydrotalcite — a…
Chementator: Slash water and energy requirements with this dyeing process
The conventional way to dye textiles is by the so-called dip process, whereby cloth is first immersed into a vat of the dying medium, then removed and dried. The dye is then thermally fixed to the textile by heating to…
Chementator: A new spin on making emulsions
Kokusan Co. (Tokyo; edlinks.chemengonline.com/5827-531) has developed a new type of emulsifier that uses centrifugal force to drive mixtures through specially designed nozzles. The system is said to be less complex than conventional high-shear mixing devices, and operates at much lower…
Chementator: New chiral compounds
BASF AG (Ludwigshafen, Germany; edlinks.chemengonline.com/5827-546) has developed a new process for producing chiral intermediates for pharmaceutical products. Without disclosing any details, BASF says the process is based on dehydrogenase enzymes for making optically active styrene oxides and aliphatic alcohols. The…
Chementator: Improved catalysts are now ready for hydrotreating petroleum fuel
Haldor Topsøe (Lyngby, Denmark; edlinks.chemengonline.com/5826-533) has introduced two new hydroprocessing catalysts, which are based on its proprietary BRIM technology. Both catalysts are nickel-molybdenum types that optimize both hydrogenation at so-called brim sites (situated on the basal-plane of the catalyst) and…
Chementator: Catalyst screening
Lanxess Deutschland GmbH (Leverkusen, Germany; edlinks.chemengonline.com/5826-548) has commissioned a parallel reactor for the screening of catalysts use in hazardous reactions, such as phosgenation and chlorination, which are commonly used to make fine chemicals. Up to now, existing automated screening devices…
Chementator: Nanotubes
Scientists at the Lawrence Livermore National Laboratory (Calif.; edlinks.chemengonline.com/5826-549), Boston College (edlinks.chemengonline.com/5826-550) and MIT (both Mass.; edlinks.chemengonline.com/5826-551) have discovered that by heating a single-walled nanotube of carbon to 3,600°F, its strength is increased by 280%. The discovery is expected to…
