Chementator: Putting the best facet on TiO2 crystals
Single crystals of high-purity, anatase titanium dioxide with a high percentage of reactive (001) facets are said to have promising applications in solar cells, photonic and optoelectronic devices, sensors and photocatalysis. However, it is the (101) crystal facets of anatase…
Chementator: Nanobatons trap oil . . . . . . as does nanopaper
Scientists at Rice University (Houston, Tex.; edlinks.chemengonline.com/7374-547) have shown how baton-shaped nanoparticles of metal and carbon can trap oil droplets in water by spontaneously assembling into tiny sacs. The particles — composed of hollow carbon nanotubes (hydrophobic) with a short…
Chementator: Speech technology for the CPI
BASF IT Services (Ludwigshafen, Germany; edlinks.chemengonline.com/7374-533) has developed a voice-activated IT system that can be used by those involved in hazard-containment. The application was pilot tested together with BASF SE’s fire department, as part of the four-year EU project called…
Newsfront: Material Marvels
Much as the chemical process industries (CPI) themselves are always evolving, so too are the engineering materials that play a role behind the scenes. While they may not always make headlines as groundbreaking scientific technologies tend to do, new…
Chementator: Add a second riser to boost propylene production from FCC residue
Axens (Rueil-Malmaison, France; edlinks.chemengonline.com/7374-534) has commercialized its new Resid Fluid Catalytic Cracking (RFCC) PetroRiser technology for the production of high yields of propylene. This new resid-to-propylene technology is part of the FCC Alliance between Axens, The Shaw Group, Inc. (Baton…

Plant Watch Evonik to close its orthoesters plant in Niederkassel... June 11, 2008 — Evonik Industries AG will be shutting down its production plant for orthoesters in Niederkassel (Germany) in the 3rd Q of this year. It has been forced…
Chementator: A clean, sustainable process for making surfactants
Alkylglyceryl ethers (AGEs) are biodegradable nonionic surfactants with excellent foaming and moisturizing properties. Up to now, AGEs have been made in batch reactors whereby the corresponding alkyl glycidyl ether (GE) is hydrolyzed in a solvent (alcohol or ethyleneglycol monoalkyl ether)…
Chementator: Engineered silk
Current silks tend to lose performance in water and yellow in sunlight. Few of the silk-producing species of insect or spider are amenable to domestication, their silks are difficult to produce using biotechnology, and it is difficult to spin those…
Chementator: A less-expensive way to produce titanium
Titanium, the ninth most abundant metal in the world, has some desirable properties — the highest strength-to-weight ratio of any metal and high-temperature and corrosion resistance. However, its high production cost has so far restricted its use mainly to aerospace…
Chementator: Magnetic nanoparticles
Researchers at the U.S. Dept.of Energy’s Ames Laboratory (Iowa; edlinks.chemengonline.com/7374-538) have developed a new method for synthesizing various magnetic nanoparticles by mimicking bacteria that produce nano-scale magnetite (Fe3O4) naturally. Despite commercial applications ranging from localized drug delivery to magnetic inks…
