A revolutionary breakthrough in terahertz remote sensing

(PhysOrg.com) -- A major breakthrough in remote wave sensing by a team of Rensselaer Polytechnic Institute researchers opens the way for detecting hidden explosives, chemical, biological agents and illegal drugs from a distance ...

Chaotic laser brings out higher precision OTDR

Professor Wang Yun Cai and his student Wang An Bang reported a new concept of optical time domain reflectometry (OTDR) based on a chaotic light correlation method. This will be useful for precise fault location in fiber links ...

Lasers used to make first boron-nitride nanotube yarn (w/ Video)

(PhysOrg.com) -- Researchers have used lasers to create the first practical macroscopic yarns from boron nitride fibers, opening the door for an array of applications, from radiation-shielded spacecraft to stronger body armor, ...

Tracing ultra-fine dust

Limit values for fine dust emissions are based on total particle weight. It is the ultra-fine particles, however, that are particularly harmful to health. A new technique separates them by size and identifies their composition ...

A New Glance on Microscopic Images

A doctoral student at the research center Forschungszentrum Dresden-Rossendorf (Germany) suggests interpreting the images generated by Kelvin probe force microscopy in a new way. She recently published her insights in the ...

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. The problem is how to find such an atom - among billions of others. Researchers at the University ...

Next generation digital maps are laser sharp

Restoring habitat for spawning species of fish, such as Atlantic salmon, starts with a geological inventory of suitable rivers and streams, and the watershed systems that support them. But the high-tech mapping tools available ...
