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…
Chementator: Making esters with microwaves
A simple, fast and clean process to make esters without a catalyst is being developed by Chemicrea Inc. (Tokyo; edlinks.chemengonline.com/7374-539) with the support of New Energy & Industrial Technology Development Organization (Kawasaki), and Gifu University (Gifu, all Japan). The process…
Chementator: Porous glass microspheres with promising potential
A method for manufacturing porous-wall, hollow-glass microspheres (PWHGMs) over an adjustable range of pore sizes promises to substitute the doped-ceramic packing material employed in various processes, by delivering improved kinetics and a denser, more uniform arrangement of active materials. The…
Chementator: A cost-effective deprotection catalyst
The use of palladium on carbon powder supports (Pd-CP) has traditionally been a commercially viable means of catalyzing deprotection reactions, despite also requiring substantive quantities of precious metal and limiting the selection of solvents due to low hydrogenation activity. However,…
Chementator: Smart pump control
Kadant AES (Queensbury, N.Y.; edlinks.chemengonline.com/7373-543) has introduced a patented control technology for high-pressure positive-displacement (HPPD) pumps, which is said to be capable of reducing energy usage by up to 60%. The so-called UniGY PhD (Pump-modeling hydraulic drive) uses pump-modeling software…
Chementator: Plastics from CO2?
Researchers from the Organic Chemistry Dept. at Newcastle University (U.K.; edlinks.chemengonline.com/7373-544) have developed aluminium (salen) complexes that exhibit "exceptional" activity for catalyzing the synthesis of cyclic carbonates from CO2 and epoxides. Cyclic carbonates are widely used for the production of…
Chementator: Improved transistor
Researchers at the Faculty of Engineering, Lund University (Sweden; edlinks.chemengonline.com/7373-545) have used nanotechnology to develop a transistor that is said to be 50 times more energy efficient that conventional models. The prototype transistor is made of indium arsenide, where the…
Chementator: A barrier for PVs
Honeywell Specialty Materials (Morristown, N.J.; edlinks.chemengonline.com/7373-546) has launched PowerShield PV325, a material that protects photovoltaic (PV) modules — including the critical components that convert sunlight into electricity — in all types of environments. The material is ultraviolet, moisture and weather…
Chementator: Catalyst loading
TubeMaster, Inc. (Louisville, Ky.; edlinks.chemengonline.com/7373-547) has filed U.S. and foreign patents for Dog-leg — claimed to be the world’s first articulating catalyst-loading device that permits loading of single and multi-layer catalyst to any height or outage, regardless of reactor vertical-head…
