NIST's new way of 'seeing': A neutron microscope
... structure--are directed into a row of 100 dimpled aluminum
plates. Each dimpled plate acts like a weak focusing lens for neutrons, diverting the neutrons' path slightly at each interface. The image then is projected onto a detector. Adelphi Technology Inc. of San Carlos, Calif., designed and demonstrated the...

Scientists learn how adjuvant makes vaccines effective
...T. Glenny read Ramone's account and decided to mix aluminum
salts, or alum, with inactivated tetanus toxin in a test vaccine he tried on rabbits. Again, the vaccine with the adjuvant was more effective than a vaccine containing the toxin alone. The adjuvant alum was first widely used in humans in the 1950s as...

A link between thimerosal and the brain: Can vaccines affect central nervous system function?
... such as ethanol and heavy metals (including lead, aluminum
and the ethylmercury-containing preservative thimerosal) potently interrupt growth factor signaling, causing adverse effects on methylation reactions (i.e. the transfer of carbon atoms). Methylation, in turn, plays a significant role in regulating no...
'Homegrown' relief for victims of arsenic poisoning in South Asia
... from water and another for a process that removes aluminum
sulfate from sludge and enables it to be reused as a coagulant in a water-treatment plant. SenGupta worked with John Greenleaf, a graduate student in environmental engineering at Lehigh, to develop a way to "impregnate" tiny, polymeric ion-exchange b...
New scheduling method raises efficiency of electronics recycling
...ucts contain valuable materials, including copper, aluminum
and steel, they also harbor hazardous substances such as lead. Although certain recycling centers specialize in electronic products, there is no software designed for the efficient scheduling of jobs within electronics recycling plants. Such scheduli...

Dartmouth researchers put recycling in perspective
... The researchers considered recycling plastic and aluminum
and used life-cycle analysis (LCA), which measures the energy and materials required to create an item and again to recycle it. For example, the study states that making a can from recycled material requires 94 percent less energy than making one fro...
