An end-to-end transmitter-receiver created by engineers in UCI's Nanoscale Communication Integrated Circuits Labs, is a 4.4-millimeter-square silicon chip that is capable of processing digital signals with significantly greater speed and energy efficiency because of its unique digital-analog architecture.
A research team led by physicists at the University of California, Riverside, has observed, characterized, and controlled dark trions in a semiconductor -- ultraclean single-layer tungsten diselenide -- a feat that could increase the capacity and alter the form of information transmission.
UK researchers have developed world-leading Compound Semiconductor (CS) technology that can drive future high-speed data communications. A team from Cardiff University's Institute for Compound Semiconductors (ICS) worked with collaborators to innovate an ultrafast and highly sensitive 'avalanche photodiode' (APD) that creates less electronic 'noise' than its silicon rivals.
Scientists developed multifunctional metal alloys that emit and absorb heat at the same time and change their size and volume under the influence of a magnetic field. This effect is caused by changes in the structure of the substance. The alloys may be used in medicine and industry.
Heavy traffic is commonplace on Earth but now congestion is becoming an increasing problem in space. With over 22,000 artificial satellites in orbit it is essential to keep track of their positions in order to avoid unexpected collisions. Amateur astronomers from the Basingstoke Astronomical Society have been helping the Ministry of Defence explore what is possible using high-end consumer equipment to track objects in space.
The use of electric propulsion for raising satellites into geostationary orbit can result in significant solar cell degradation according to a new study being presented at the Royal Astronomical Society's National Astronomy Meeting. The extended journey time results in greater exposure to the damaging effects of space weather. Understanding the size of this risk is essential for commercial satellite operators to take steps to mitigate the effects and protect their assets.
Professor Kilwon Cho of Chemical Engineering and Professor Yoonyoung Chung of Electronic and Electric Engineering from POSTECH successfully developed a flexible and wearable vibration responsive sensor. When this sensor is attached to a neck, it can precisely recognize voice through vibration of the neck skin and is not affected by ambient noise or the volume of sound.
New research shows that hackers, working with limited resources, could send fake emergency alerts to cell phones in a confined area like a sports stadium.
A new type of computer memory to solve the digital technology energy crisis has been invented and patented by scientists. The device is the realization of the decades long search for a 'Universal Memory' to replace the $100 billion market for Dynamic Random Access Memory (DRAM) and flash drives. It promises to transform daily life with its ultra-low energy consumption, allowing computers which do not need to boot up and which could sleep between key strokes.
It sounds like an old-school vinyl record, but the distinctive crackle in the music streamed into Chris Holloway's laboratory is atomic in origin. The group spent years finding a way to directly measure electric fields using atoms. They don't expect the atomic-recording's lower sound quality to replace digital music recordings, but the team is considering how this 'entertaining' example of atomic sensing could be applied in communication devices of the future.
