An international team with the participation of Prof. Dr. Michael Kues from the Cluster of Excellence PhoenixD at Leibniz University Hannover has developed a new method for generating quantum-entangled photons in a spectral range of light that was previously inaccessible. The discovery can make the encryption of satellite-based communications much more secure in the future.
Researchers at Los Alamos National Laboratory are reinventing the mirror, at least for microwaves, potentially replacing the familiar 3-D dishes and microwave horns we see on rooftops and cell towers with flat panels that are compact, versatile, and better adapted for modern communication technologies.
searchers from the Zepler Institute for Photonics and Nanoelectronics at the University of Southampton have demonstrated a new leap in hollow-core fibre performance, underlining the technology's potential to soon eclipse current optical fibres.
A room-temperature bonding technique for integrating wide bandgap materials such as gallium nitride (GaN) with thermally-conducting materials such as diamond could boost the cooling effect on GaN devices and facilitate better performance through higher power levels, longer device lifetime, improved reliability and reduced manufacturing costs.
A fascinating new study has shown that the duration of a text-based counseling session, the length of the counselor's messages, and quick response time by the counselor are important factors in determining the impact of counseling.
Researchers at Drexel University and the Materials Research Center in Ukraine have designed a system that can be used to make large quantities of the material while preserving its unique properties. The team recently reported in the journal Advanced Engineering Materials that a lab-scale reactor system developed at the Materials Research Center in Kyiv, can convert a ceramic precursor material into a pile of the powdery black MXene titanium carbide, in quantities as large as 50 grams per batch.
The US is witnessing a dramatic rise in nontraditional 'gig economy' labor markets. Research examined the work of over 20,000 men and women completing over 5 million tasks online, and found a gender pay gap not accounted for by demographics, task preferences, or experience. On average, women's hourly earnings were 10.5% lower than men's. This is the first study to provide evidence that pay gaps can arise despite the absence of overt discrimination, labor segregation, and inflexible work arrangements.
Technology has shifted the way that professors teach students in higher education. For example, by uploading recorded lectures online, students can reference a digital copy of the topics discussed in class. However, lecture-based teaching traditionally leaves students as consumers of information solely with little room for student creativity or interaction.
Researchers in South Korea have developed a new optical communications technology that can transfer data in lightning speed. The new technology sends and receives twice as much data than conventional methods. It is expected to contribute to solving data traffic congestion in 5G networks.
The researchers tricked photons - which are intrinsically non-magnetic - into behaving like charged electrons. They accomplished this by sending the photons through carefully designed mazes in a way that caused the light particles to behave as if they were being acted upon by what the scientists called a "synthetic" or "artificial" magnetic field.
