Oil Refineries Could Improve Energy Efficiency With New Method

Chemical plants spend from 50 to 70 percent of their energy in "separations," which are usually distillation steps required to separate a raw material into various products. An energy-efficient Purdue University method rearranges the distillation sequence needed to separate crude petroleum into products.

Should whole body imaging be used for airport security?

The first Question of the Week for 2010 concerns airline security. The recent foiled attempt by a Nigerian terrorist to set off a bomb aboard a Northwest Airlines flight landing in Detroit has renewed concerns that current X-ray technology is insufficient in detecting concealed weapons and substances. The Transportation Security Administration (TSA) already has a pilot program in place at six airports deploying millimeter-wave machines, which produce a 3-D image of the body, in place of X-ray machines. But some government officials worry these machines violate the privacy of individuals such as women and children.

What do you think? Should whole body imaging be used for airport security? Yes or no?

Recovering Raw Materials for Green Technologies

Engineering researchers from the University of Leeds have discovered how to recover significant quantities of rare-earth oxides, present in titanium dioxide minerals. Rare-earth oxides are useful in many applications, such as the manufacture of wind turbines, energy-efficient lighting, and hybrid and electric cars.

Bacteria Turns Carbon Dioxide Into Liquid Fuel

Researchers from the UCLA Henry Samueli School of Engineering and Applied Science have genetically modified a cyanobacterium to consume carbon dioxide and produce the liquid fuel isobutanol, which has great potential as a gasoline alternative. The reaction is powered directly by energy from sunlight, through photosynthesis.

New Nano-Material Could Revolutionize Solar Panels and Batteries

Tel Aviv University researchers have found a novel way to control the atoms and molecules of peptides so that they "grow" to resemble small forests of grass. These "peptide forests" repel dust and water — a perfect self-cleaning coating for windows or solar panels which, when dirty, become far less efficient.
