Researchers at Dukes Pratt School of Engineering have developed a new way to measure microbes exposure to ultraviolet light. The tool could bolster efforts to use UV light to improve the quality and safety of tap water in the U.S.
The novel "microsphere dosimeter" technique is the first direct test of how much UV light microorganisms in fluids have been exposed to, said the researchers -- a critical step in validating the use of UV light treatment for preventing the spread of infection through drinking water. The technique was reported in the Nov. 15, 2005, issue of Environmental Science and Technology by Karl Linden and colleagues.
Lindens technique uses fluorescent microspheres, which become bleached with exposure to UV light, to mimic pathogenic microbes in water flowing through a UV reactor. By measuring the bleaching of the microspheres, the researchers can obtain precise measures of the full distribution of UV doses that a pathogen may experience -- information critical for gauging the treatments capacity to kill disease-causing bacteria or parasites before they reach the public.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
