World record in silicon integrated nanophotonics: More energy efficiency in the data communication
Researchers at the University of Stuttgart, Germany, achieved a new world record in the energy efficient integration in silicon. This is an important step to decrease the energy consumption of data transfer ...
Listening to blood cells: Simple test could use sound waves for diagnosing blood-related diseases
New research reveals that when red blood cells are hit with laser light, they produce high frequency sound waves that contain a great deal of information. Similar to the way one can hear the voices of different ...
Researchers discover way to allow 80 percent of sound to pass through walls
Ferroelectric-graphene-based system could lead to improved information processing
Researchers at MIT have proposed a new system that combines ferroelectric materials—the kind often used for data storage—with graphene, a two-dimensional form of carbon known for its exceptional electronic ...
Meta-transmitarray offers unprecedented control of light on subwavelength scales
Researchers create design for nanometer-scale material that can speed up, squeeze light
(Phys.org) —In a process one researcher compares to squeezing an elephant through a pinhole, researchers at Missouri University of Science and Technology have designed a way to engineer atoms capable of ...
Liquid crystal's chaotic inner dynamics
Scientists have unearthed a new dynamic process induced by strong electric fields in thin liquid crystal cells.
Cutting light with a comb
(Phys.org)—Quantum physicists from ETH Zurich have discovered special properties in a laser, thanks to which portable devices can be built to analyse gases and liquids accurately and reliably in the future.
New technique excites atoms and molecules using pulsed laser
The best method to obtain the most precise information on the inner structure of atoms and molecules is to excite them by means of resonant laser light. Unfortunately, just this laser light (above a certain ...
'Lab-on-a-chip' to accelarate, enhance medical testing, researcher says
(Phys.org)—Suppose you are sick enough to go to an emergency room. A physician examines you and decides that some blood tests are warranted. A phlebotomist draws the blood and sends it to a lab for testing. ...
Electromagnetic cloaking possible with ordinary plastic, study finds
A metal object can be made invisible with the help of ordinary plastic, Pekka Alitalo and Constantinos Valagiannopoulos, researchers from the School of Electrical Engineering, have shown in their study.
Spacetime ripples from dying black holes could help reveal how they formed
(Phys.org)—Researchers from Cardiff University have discovered a new property of black holes: their dying tones could reveal the cosmic crash that produced them.
Light beams offer bright future for lighter-weight cars
(Phys.org)—Beams of light could one day replace the jumble of wires under a car bonnet, leading to lighter-weight and more fuel-efficient vehicles.
