New antennas so thin that they can be sprayed into place are also robust enough to provide a strong signal at bandwidths that will be used by fifth-generation (5G) mobile devices. Performance results for the antennas, which are made from a new type of two-dimensional material called MXene, were recently reported by researchers at Drexel University and could have rammifications for mobile, wearable and connected "internet of things" technology.
Scientists of Far Eastern Federal University (FEFU) with international collaborators propose direct magnetic writing of skyrmions, i.e. magnetic quasiparticles, and skyrmion lattices, within which it is possible to encode, transmit, process information, and produce topological patterns with a resolution of less than 100 nanometers. This brings closer miniaturized post-silicon electronics, new topological cryptography techniques, and green data centers, reducing the load on the Earth's ecosystem significantly. A related article appears in ACS Nano.
Analysis of social media messages between care home staff on the coronavirus front line reveal their growing concerns over how to manage in the face of the virus. Workers were often asking questions which went unanswered due to a lack of proper guidance.
SUTD researchers develop technology which allows for photonic integrated circuits to unlock their potential as high resolution 3D photonic structures in ultra-high speed communications.
Researchers at the George Washington University have developed a new design of vertical-cavity surface-emitting laser (VCSEL) that demonstrates record-fast temporal bandwidth.
A study by Giovanni Geraci, a researcher at the Department of Information and Communication Technologies, and researchers at Mississippi State University (USA), which aims to improve the security of advanced wireless networks against a series of eavesdropping, interference and identity theft.
To understand how telemedicine compensated for declining outpatient volume and geographic variation in changing patterns of outpatient care, researchers examined telemedicine and in-person outpatient visits in 2020 among a national sample of 16.7 million people with commercial or Medicare Advantage insurance.
Researchers in Japan have demonstrated a silicon-polymer hybrid modulator that can efficiently and reliably transmit data at 200 Gbit/s over an extremely wide range of temperatures from 25 °C to 110 °C. Use of such robust modulators in high-speed data applications could reduce cooling demands of the systems and expand applications in harsh environments.
A new device created by researchers at The University of Texas at Austin can overcome challenges like bad weather to deliver more secure, reliable communications. This could aid military communications in challenging areas, improve the ability of self-driving cars to see the environment around them and speed up wireless data for potential 6G networks.
A mathematical model shows specialized reflective panels could be deployed on a large scale to enhance communication networks in urban areas.
