New study: Why solar cells lose potency
Commercial products such as laptop computer monitors and solar-powered calculators are constructed from a light-sensitive material with a peculiar problem: When exposed to intense light, it forms defects, reducing the efficiency of the solar cells by 10 to 15 percent. view more (2005-06-20)
ANALYTICA 2004: The 5 Minute PCR
At Analytica 2004, the Institut für Mikrotechnik Mainz GmbH (IMM) presents the prototype of its modular kit for a "chip-based lab". Thanks to the special microfluidic system and a miniaturized tempering unit, the modular construction system makes it possible to realize reproduceable polymerase chain reactions in less than five... view more...

Special chip provides better picture of salmon health
How do you tell if a fish is fit and well? This is a question which has troubled farmers and biologists for years, but now scientists may have come up with the answer-using DNA chips. view more (2006-10-17)
Unique locks on microchips could reduce hardware piracy
Hardware piracy, or making knock-off microchips based on stolen blueprints, is a burgeoning problem in the electronics industry. view more (2008-03-06)
UD researchers put 'spin' in silicon, advance new age of electronics
Electrical engineers from the University of Delaware and Cambridge NanoTech have demonstrated for the first time how the spin properties of electrons in silicon--the world's most dominant semiconductor, used in electronics ranging from computers to cell phones--can be measured and controlled. view more (2007-05-21)
Novel NIST connector uses magnets for leak-free microfluidic devices
Like other users of microfluidic systems, National Institute of Standards and Technology (NIST) researcher Javier Atencia was faced with an annoying engineering problem: how to simply, reliably and most of all, tightly, connect his tiny devices to the external pumps and reservoirs delivering liquids into the system. view more (2009-11-18)
Sensor biochips could aid in cancer diagnosis and treatment
It is very difficult to predict whether a cancer drug will help an individual patient: only around one third of drugs will work directly in a given patient. view more (2009-10-22)
Custom-sized microlenses
Optical components have joined the trend towards miniaturization. There have, however, been no methods available thus far to produce custom-sized glass lenses. A new process now enables the low-cost, high-volume manufacture of microlenses with extreme dimensions. view more (2004-08-27)
Mapping dynamic Polycomb group proteins during Drosophila development
The developmental passage from a ball of cells to a fruit-fly is a very complicated process involving both temporal and spatial regulation of genes and pathways. view more (2006-04-20)
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)
Computer Technology Developed By Hebrew University Professor Can Save Lives For Drivers
No one likes a back-seat driver. But imagine having a silent "co-pilot" in your car that isn't a pest but can save your life, as well as those of your passengers and those in the path of your vehicle. That's what EyeQ, a computer chip developed by MobilEye -- a company founded by Prof. Amnon Shashua, chairman of the Hebrew University of... view more... (2004-06-27)
Graphitic memory techniques advance at Rice
Advances by the Rice University lab of James Tour have brought graphite's potential as a mass data storage medium a step closer to reality and created the potential for reprogrammable gate arrays that could bring about a revolution in integrated circuit logic design. view more (2009-09-10)
A bright future for plastics -- robot 'skin,' flexible laptops and electric posters
With market analysts predicting a ten fold increase in the value of the organic light emitting display industry, from £1.5 billion to £15.5 billion, by 2014, it is no wonder that scientists and governments alike are keen to advance research into "plastic electronics". view more (2008-07-01)
Saliva can help diagnose heart attack, study shows
Early diagnosis of a heart attack may now be possible using only a few drops of saliva and a new nano-bio-chip, a multi-institutional team led by researchers at The University of Texas at Austin reported at a recent meeting of the American Association for Dental Research. view more (2008-04-17)
Manchester physicists pioneer new super-thin technology
Researchers have used the world's thinnest material to create a new type of technology, which could be used to make super-fast electronic components and speed up the development of drugs. view more (2007-03-01)
Sharply-tuned nanostrings work at room temperature
Using a fast, low-cost fabrication technique that allows inexpensive testing of a wide variety of materials, Cornell researchers have come up with nanoscale resonators - tiny vibrating strings - with the highest quality factor so far obtainable at room temperature for devices so small. view more (2006-07-17)
Georgia Tech/IBM team demonstrates first 500 GHz silicon-germanium transistors
A research team from IBM and the Georgia Institute of Technology has demonstrated the first silicon-germanium transistor able to operate at frequencies above 500 GHz. view more (2006-06-20)
Caltech bioengineers develop 'microscope on a chip'
Researchers at the California Institute of Technology have turned science fiction into reality with their development of a super-compact high-resolution microscope, small enough to fit on a finger tip. view more (2008-07-29)
NRL generates, modulates, and electrically detects pure spin currents in silicon
Scientists at the Naval Research Laboratory (NRL) have generated, modulated and electrically detected a pure spin current in silicon, the semiconductor used most widely in the electronic device industry. view more (2007-12-04)
'Radio wave cooling' offers new twist on laser cooling
Visible and ultraviolet laser light has been used for years to cool trapped atoms-and more recently larger objects-by reducing the extent of their thermal motion. view more (2007-09-17)
