Green Catalysts Provide Promise For Cleaning Toxins And Pollutants
Tetra-Amido Macrocyclic Ligands are environmentally friendly catalysts with a host of applications for reducing and cleaning up pollutants, and a prime example of "green chemistry." Carnegie Mellon University's Terry Collins,...
Heads-up Study Of Hair Dynamics May Lead To Better Hair-care Products
From frizzy perms to over-bleached waves, "bad hair days" could soon become a less frequent occurrence. Chemists report the first detailed microscopic analysis of what happens to individual hair fibers...
Researchers Build World's Smallest SRAM Memory Cell
(PhysOrg.com) -- IBM and its development partners -- AMD, Freescale, STMicroelectronics, Toshiba and the College of Nanoscale Science and Engineering (CNSE) -- today announced the first working static random access...
Science closer to organic spin transistor
SALT LAKE CITY, Aug. 18 (UPI) -- U.S. physicists say they've moved closer to making an organic "spin transistor" by controlling electrical current using the "spin" within electrons.
Physicists Transmit Light through Opaque Materials
No matter how thick an opaque "scattering material" is, physicists have shown how to weave light through tiny open channels in the material, so that the light passes through on...
Patterning promise for next-gen computers
Self-assembling polymers hold key to computer components of the future
New Speed Record for Magnetic Memories
(PhysOrg.com) -- An experiment carried out at the Physikalisch-Technische Bundesanstalt (PTB) has realized spin torque switching of a nanomagnet as fast as the fundamental speed limit allows. Using this so-called...
Chemists Make Beds With Soft Landings: Researchers Create Stable, Highly Pure Helical Peptide Arrays
Bedsprings aren't often found in biology. Now, chemists have secured a layer of tiny protein coils onto a thin surface, much like miniature bedsprings in a frame. This thin film...
Solar method makes clean fuel
Using a trick developed by plants, researchers have found a way to make hydrogen using sunlight – which could be very helpful for solar cells.
Gel undergoes Peristalsis
Large or small, machine parts only move when controlled by an external impulse. Biological systems, on the other hand, are capable of autonomous movements that continuously follow their own rhythms...
Improved Technique Determines Structure In Membrane Proteins
By combining custom-built spectrometers, novel probe designs and faster pulse sequences, scientists have developed unique capabilities for probing protein chemistry and structure through the use of solid-state nuclear magnetic resonance...
Safer Alternative To Heparin Created
Robert Linhardt has spent years stitching together minuscule carbohydrates to build a more pure and safer alternative to the commonly used and controversial blood thinner heparin. Now he has announced...
Using Sunlight To Split Water Into Hydrogen And Oxygen By Replicating Key Process In Photosynthesis
Chemists have used chemicals found in plants to replicate a key process in photosynthesis paving the way to a new approach that uses sunlight to split water into hydrogen and...
Plug-In Hybrid From G.M. Is Nearly Ready for Testing
General Motors said that it had “essentially finished” designing its first plug-in hybrid car and would have production-ready prototypes within 10 days.
Two Large Solar Plants Planned in California
Two California companies plan to build solar power plants 10 times larger than the largest now in service, creating the first utility-scale use of technology mostly confined to rooftops.
Caltech engineers build mini drug-producing biofactories in yeast
Researchers at the California Institute of Technology have developed a novel way to churn out large quantities of drugs, including antiplaque toothpaste additives, antibiotics, nicotine, and even morphine, using mini...
Cool Back-To-School Gadgets
CNET-TV's Natali Del Conti showcased several, from an electronic "crammer" to a portable printer and a kids' laptop, on The Early Show.
Ames lab physicist develops 'electrifying' theory
John R. Clem, a physicist at the U.S. Department of Energy's Ames Laboratory, has developed a theory that will help build future superconducting alternating-current fault-current limiters for electricity transmission and...
Film Review: 'Star Wars: The Clone Wars'
The Star Wars universe rides again in the new animated film 'The Clone Wars.'
The Large Hadron Collider: 'Seeing nothing is not an option'
Sept. 10 is a date particle physicists around the world have undoubtedly circled on their calendars: the official start-up of the Large Hadron Collider.
Airlines push for homegrown jet fuel
(AP) -- With the price of oil still above $100 a barrel, everything from wood chips to chicken fat is being scrutinized as an alternative to traditional fuel. But...
True Properties Of Carbon Nanotubes Measured
Carbon nanotubes' atomic structure should, in theory, give them mechanical and electrical properties far superior to most common materials. Unfortunately, theory and experiments have failed to converge on the true...
Dual-Mode Nanoparticles Image Tumors Using MRI and PET
Medical imaging represents one of the most used and useful procedures in the oncologist`s diagnostic toolkit, even though each of the most useful techniques—magnetic resonance imaging (MRI), computerized tomography x-ray...
