Nano-sediment highways in catalyst
Dutch chemists have visualised how the porous structure of a zeolite catalyst depends on the production method. Zeolite made with carbon fibres as a template, has particles with straight canals that act as highways for the oil components which must be converted into benzene components. Zeolite is normally given a steam treatment to improve its... view more... (2003-03-21)
Measuring invisible reflections
The race is on for chip manufacturers. Many of them plan to open chip fabrication facilities employing extreme ultraviolet (EUV) radiation between up until 2010. This trend is being driven by advances in photolithography in which increasingly shorter wavelengths enable the production of even finer microelectronic structures. The result is higher... view more... (2003-07-25)
Antiprotons 4 times more effective than protons for cell irradiation
A pioneering experiment at CERN with potential future application in cancer therapy has produced its first results. Started in 2003, ACE (Antiproton Cell Experiment) is the first investigation of the biological effects of antiprotons. view more (2006-11-01)
Electron filmed for first time ever
Now it is possible to see a movie of an electron. The movie shows how an electron rides on a light wave after just having been pulled away from an atom. view more (2008-02-25)
Living Metals
Using synchrotron x-ray microbeams, a research team from the Max Planck Institute for Metals Research in Stuttgart and the ESRF has been able to observe for the first time that the microscopic structure of a crystalline material fluctuates in time. The results are published today in Science Express with the title: Scaling in the Time Domain:... view more... (2005-04-22)
Solving a subatomic shell game
Physicists at Michigan Technological University have filled in some longtime blank spaces on the periodic table, calculating electron affinities of the lanthanides, a series of 15 elements known as rare earths. view more (2009-03-24)
Tackling brake noise
The squeal of brakes is not just irritating and annoying, it damages cars and railway wheel squeal is a serious environmental concern, contributing significantly to inner city noise pollution. EUREKA project E! 2122 BRAKENOISE is tackling the friction-induced vibration that can cause such excessive undesirable noise. The project partners - Bosch,... view more... (2004-01-07)
Research Paper Illuminates How Light Pushes Atoms
A research paper published in the 18 August edition of the journal Physical Review Letters reveals a new effect in the fundamental way that laser light interacts with atoms. view more (2006-08-21)
Racing Ahead at the Speed of Light
Imagine trying to catch up to something moving close to the speed of light - the fastest anything can move - and sending ahead information in time to make mid-path flight corrections. Impossible? Not quite. view more (2008-02-07)
British scientists create electron surf machine
By precisely controlling billions of individual electrons every second, they hope to develop new computing systems and increase the security of digital communication. view more (2007-06-13)
Proton beam therapy may improve treatment of rare but aggressive tumor
Proton beam radiation therapy, a very precise type of radiation treatment, may be an effective treatment for advanced adenoid cystic carcinoma that has spread to the cranial base, according to a study from the Francis H. Burr Proton Therapy Center at Massachusetts General Hospital (MGH). view more (2006-11-21)
Synchrotron radiation illuminates how babies' protective bubble bursts
Researchers at the University of Reading, School of Pharmacy have developed an important new technique to study one of the most common causes of premature birth and prenatal mortality. view more (2007-11-07)
Spallation Neutron Source first of its kind to reach megawatt power
The Department of Energy's Spallation Neutron Source (SNS), already the world's most powerful facility for pulsed neutron scattering science, is now the first pulsed spallation neutron source to break the one-megawatt barrier. view more (2009-09-30)
Spallation Neutron Source sends first neutrons to 'Big Bang' beam line
New analytical tools coming on line at the Spallation Neutron Source, the Department of Energy's state-of-the-art neutron science facility at Oak Ridge National Laboratory, include a beam line dedicated to nuclear physics studies. view more (2008-10-10)
Growth Spurts: Berkeley Lab Researchers Record First Real-Time Direct Observations of Nanocrystal Growth in Solution
The veil is being lifted from the once unseen world of molecular activity. Not so long ago only the final products were visible and scientists were forced to gauge the processes behind those products by ensemble averages of many molecules. view more (2009-08-10)
Researchers putting a freeze on oscillator vibrations
University of Oregon physicists have successfully landed a one-two punch on a tiny glass sphere, refrigerating it in liquid helium and then dosing its perimeter with a laser beam, to bring its naturally occurring mechanical vibrations to a near standstill. view more (2009-06-18)
New imaging technique reveals the atomic structure of nanocrystals
A new imaging technique developed by researchers at the University of Illinois overcomes the limit of diffraction and can reveal the atomic structure of a single nanocrystal with a resolution of less than one angstrom (less than one hundred-millionth of a centimeter). view more (2009-02-19)
Toward a quantum computer, one dot at a time
Researchers at the University of Pittsburgh have developed a way to create semiconductor islands smaller than 10 nanometers in scale, known as quantum dots. view more (2006-01-20)
Precision radiation therapy yields rare success for liver tumors
Shaped-beam radiation therapy is a promising treatment for life-threatening metastatic liver tumors, according to researchers at the University of Rochester Medical Center who report an 88 percent success rate for controlling the lesions. view more (2005-10-20)
Groundbreaking Superstem Microscope Opened At Daresbury Laboratory
The science minister, Lord Sainsbury, will today open the highest resolution analytical microscope in the world at the CCLRC Daresbury Laboratory in Cheshire. The SuperSTEM (Scanning Transmission Electron Microscope) project is directed by Professor Peter Goodhew at Liverpool University and involves other scientists from the Universities of... view more...
