Plastic as hard and clear as glass
Plastics come in many forms. They are used to make boats, magnifiers, skis and all manner of household items. Transparent plastic sheet panels would be ideal in the manufacture of windows or headlamps of cars, for example, and tinted plastic foils could more readily be used to protect against the sun – if only the material was not so easily... view more...

HERA GETS GOING WITH ELECTRONS
The Hadron Electron Ring Accelerator (HERA) at the DESY laboratory in Hamburg is about to begin operations for 1998 with a return to electrons. Since 1993, the machine has been producing head-on collisions between high-energy protons and positrons - the antimatter equivalent of electrons. Now it is ready to get going with electrons again. view more (1998-08-11)
'Racetrack' for fast electrons in semiconductor structures
In order to realize the electrical units of voltage, resistance and current with highest accuracy quantum effects in nano-circuits are nowadays used. Important prerequisites are extremely pure semiconductor layers where high-mobile electrons move through the crystal without collision with residual impurities. view more (2008-08-29)
New laser technique may help find supernova
One single atom of a certain isotope of hafnium found on Earth would prove that a supernova once exploded near our solar system. view more (2009-08-12)
A new technique for building nanodevices in the lab
Physicists at the University of Pennsylvania are using a new technique to craft some of the tiniest metal nanostructures ever created, none larger than 10 nanometers, or 10,000 times smaller than the width of a single human hair. view more (2007-06-26)
Potential leap forward in electron microscopy
MIT electrical engineers have proposed a new scheme that can overcome a critical limitation of high-resolution electron microscopes: they cannot be used to image living cells because the electrons destroy the samples. view more (2009-10-07)
Cone-beam CT: Just as useful as MDCT before and after percutaneous vertebroplasty
Cone-beam CT which is believed to deliver less radiation than MDCT is just as useful when evaluating patients before and after percutaneous vertebroplasty according to a study performed at the Department of Clinical Radiology, Kyushu University, Fukoka, Japan. view more (2008-11-04)
New technique measures chemical composition of tiny details
The method which the Eindhoven have developed is based on the radiation emitted by an object when it is irradiated by a beam of electrons. The measurable phenomenon occurs because the electrons in the beam collide with electrons in the atoms making up the object so that they enter an excited state. When the electrons return to the free state, with... view more... (2000-01-18)
STFC Daresbury Laboratory's ALICE accelerates to 4 million volt milestone
A major milestone has been achieved in the completion of the UK's next-generation particle accelerator, ALICE, which is set to produce an intense beam of light that will revolutionise the way in which accelerator based light source research facilities will be designed in the future. view more (2008-11-18)
Carefully Mixed Radiation Cocktail Reduces Collateral Damage In Breast Cancer Patients
A carefully determined mixture of electron and x-ray beams precisely treated breast tumors while significantly reducing collateral skin damage in 78 patients. view more (2006-07-31)
Study finds that seeing plaque buildup prompts patients to comply with medications
A new study has found that seeing the build-up of plaque in their own arteries is the incentive patients need to comply with doctor's orders. view more (2006-04-26)
Inside a quantum dot: Tracking electrons at trillionths of a second
Researchers at the EPFL (Ecole Polytechnique Federale de Lausanne) have developed a new machine that can reveal how electrons behave inside a single nano-object. view more (2005-11-28)
Modified electron microscope identifies atoms
A new electron microscope recently installed in Cornell's Duffield Hall is enabling scientists for the first time to form images that uniquely identify individual atoms in a crystal and see how those atoms bond to one another. And in living color. view more (2008-02-22)
By color-coding atoms, new Cornell electron microscope promises big advance in materials analysis
A new electron microscope recently installed in Cornell's Duffield Hall is enabling scientists for the first time to form images that uniquely identify individual atoms in a crystal and see how those atoms bond to one another. And in living color. view more (2008-02-22)
Dual-focus lenses cut thick metal fastest
V&S Scientific, the UK company that licenses the technology from the Force Institute in Denmark, says that demand for the dual focus lenses is beyond expectation, even though they cost much more than conventional optics for laser cutting. The company exceeded its 1999 sales projections for the lenses by the Spring, reports the July issue of Opto... view more... (1999-06-30)
High in sodium: Highly charged tungsten ions may diagnose fusion energy reactors
Just as health-food manufacturers work on developing the best possible sodium substitutes for low-salt diets, physicists at the National Institute of Standards and Technology (NIST) have acquired new knowledge on a promising sodium alternative of their own. view more (2009-09-10)
Full 3-D image of nanocrystals' interior created by shining X-rays through them
A vital step towards the ultimate goal of being able to take 'photographs' of individual molecules in action has been achieved by an international team led by UCL (University College London) researchers at the London Centre for Nanotechnology. view more (2006-07-06)
Proton therapy lowers chance of later cancers
Patients who are treated with proton therapy (a specialized type of external beam radiation therapy using protons rather than X-rays to treat cancer) decreases the risk of patients developing a secondary cancer by two-fold, compared to being treated with standard photon radiation treatment. view more (2008-09-22)
Electron self-injection into an evolving plasma bubble
Particle accelerators are among the largest and most expensive scientific instruments. Thirty years ago, theorists John Dawson and Toshiki Tajima proposed an idea for making them thousands of times smaller: surf the particles on plasma waves driven by short intense laser pulses. view more (2009-11-03)
Surprisingly, Chemists Find, Some Solvents Can Alter Chemical Bonds
New University at Buffalo research demonstrates that some solvents can significantly enhance certain acid-base interactions and strengthen the bonding interaction between two molecules when one is electron-deficient and one is electron-rich. view more (2007-07-25)
