Uncharged organic molecule can bind negatively charged ions
Indiana University Bloomington chemists have designed an organic molecule that binds negatively charged ions, a feat they hope will lead to the development of a whole new molecular toolbox for biologists, chemists and medical researchers who want to remove chlorine, fluorine and other negatively charged ions from their solutions. view more (2008-02-27)
The man from Southampton-he says yes!
23 October 1998 How do farmers know when their tomatoes are perfect and just right for picking? Southampton researchers have harnessed the same technology used to print T-shirts to develop a simple, robust device that can be used in the field to indicate when fruit is ripe. John Atkinson, head of the University of Southampton's Thick Film Unit... view more... (1998-11-17)
Diabetics to benefit as clinical chemistry gets under the skin
Water makes up more than 70 percent of our bodies, and our skin works like an oily film providing an effective barrier to keep water and the other charged substances inside us. But skin is not an impermeable material, and charged substances from inside the body can be made to cross the skin barrier by applying an electric field. Iontophoresis is a... view more...

Queen's scientists find new way to battle MRSA
Experts from Queen's University Belfast have developed new agents to fight MRSA and other hospital-acquired infections that are resistant to antibiotics. The fluids are a class of ionic liquids that not only kill colonies of these dangerous microbes, they also prevent their growth. view more (2009-03-25)
Penn team uses self-assembly to make molecule-sized particles with patches of charge
Physicists, chemists and engineers at the University of Pennsylvania have demonstrated a novel method for the controlled formation of patchy particles, using charged, self-assembling molecules that may one day serve as drug-delivery vehicles to combat disease and perhaps be used in small batteries that store and release charge. view more (2009-10-21)
New technology has dramatic chip-cooling potential for future computers
Researchers have demonstrated a new technology using tiny "ionic wind engines" that might dramatically improve computer chip cooling, possibly addressing a looming threat to future advances in computers and electronics. view more (2007-08-14)
ABCB6 is key to production of heme in hemoglobin
Investigators at St. Jude Children's Research Hospital have discovered that a protein called ABCB6 plays a central role in production of a molecule that is key to the ability of red blood cells to carry oxygen, of liver cells to break down toxins, and of cells to extract energy from nutrients. view more (2006-09-29)
Hot and cold moves of cyanide and water
Scientists have long known that molecules dance about as the temperature rises, but now researchers know the exact steps that water takes with a certain molecule. view more (2009-09-03)
NIST demonstrates better memory with quantum computer bits
Physicists at the National Institute of Standards and Technology (NIST) have used charged atoms (ions) to demonstrate a quantum physics version of computer memory lasting longer than 10 seconds-more than 100,000 times longer than in previous experiments on the same ions. view more (2005-08-11)
Semiconductor membrane mimics biological behavior of ion channels
A semiconductor membrane designed by researchers at the University of Illinois could offer more flexibility and better electrical performance than biological membranes. view more (2007-07-13)
Cluster opens a new window on 'magnetic reconnection' in the near-Earth space
Plasma physicists have made an unprecedented measurement in their study of the Earth's magnetic field. Thanks to ESA's Cluster satellites they detected an electric field thought to be a key element in the process of 'magnetic reconnection'. view more (2007-03-13)
Polarized particles join toolbox for building unique structures
Researchers at the University of Illinois at Urbana-Champaign have created polarized, spherical particles that spontaneously self-assemble into clusters with specific shapes and distributions of electric charge. view more (2006-10-13)
New plasma transistor could create sharper displays
By integrating a solid-state electron emitter and a microcavity plasma device, researchers at the University of Illinois have created a plasma transistor that could be used to make lighter, less expensive and higher resolution flat-panel displays. view more (2009-02-05)
The solution to a 7-decade mystery is crystal-clear to FSU chemist
A Florida State University researcher has helped solve a scientific mystery that stumped chemists for nearly seven decades. In so doing, his team's findings may lead to the development of more-powerful computer memories and lasers. view more (2007-10-22)
Researchers study role of natural organic matter in environment
The decomposition of plant, animal and microbial material in soil and water produces a variety of complex organic molecules, collectively called natural organic matter. These compounds play many important roles in the environment. view more (2006-12-12)
Researchers reveal HIV peptide's possible pathway into the cell
Two theoretical physicists at Rensselaer Polytechnic Institute have uncovered what they believe is the long-sought-after pathway that an HIV peptide takes to enter healthy cells. The theorists analyzed two years of biocomputation and simulation to uncover a surprisingly simple mechanism describing how this protein fragment penetrates the cell... view more... (2008-01-18)
New ion trap may lead to large quantum computers
Physicists at the National Institute of Standards and Technology (NIST) have designed and built a novel electromagnetic trap for ions that could be easily mass produced to potentially make quantum computers large enough for practical use. view more (2006-07-07)
Detecting anthrax proteins at ultralow concentrations
A new laboratory method for quickly detecting active anthrax proteins within an infected blood sample at extremely low levels has been developed. view more (2005-08-29)
X marks the spot: Ions coldly go through NIST trap junction
Physicists at the National Institute of Standards and Technology (NIST) have demonstrated a new ion trap that enables ions to go through an intersection while keeping their cool. view more (2009-04-09)
Electrostatic surface cleaning
It's often the little things that count in industrial manufacturing processes. Particles less than half the diameter of a hair in size can significantly impair quality in production. view more (2009-10-08)
