Researchers at Oregon State University have designed and fabricated the world’s smallest electro-optic modulator, which could mean major reductions in energy used by data centers and supercomputers. An electro-optic modulator plays the key role in fiber optic networks. Just as a transistor is a switch for electronic signals, an electro-optic modulator is a switch for …
Nature Materials – SiGe epitaxial memory for neuromorphic computing with reproducible high performance based on engineered dislocations Although several types of architecture combining memory cells and transistors have been used to demonstrate artificial synaptic arrays, they usually present limited scalability and high power consumption. Transistor-free analog switching devices may overcome these limitations, yet the typical …
Extreme ultraviolet lithography (EUV) is set to enable 10-nm and 7-nm process nodes over the next few years, but significant work is still needed on photoresists to enable 5-nm chips. ASML has plans in place to increase uptime of the systems from about 75% today to 90%, a top concern for lithographers, said Jones. In …
Wenchang Spacecraft Launch Site on Hainan Island is the main space launch site for China. It is one of the two spacecraft launch sites of Xichang Satellite Launch Center. It is a former sub-orbital test center. It is China’s fourth and southernmost space vehicle launch facility (spaceport). It has been specially selected for its low …
Sniping is weaponized math. Although a .50 caliber sniper rifle bullet can fly as far as five miles, a host of factors including gravity, wind speed and direction, altitude, barometric pressure, humidity and even the Coriolis Effect act upon the bullet as it travels. Even worse, these effects increase the farther the bullet travels. A …
NASA has successfully applied a new technology in flight that allows aircraft to fold their wings to different angles while in the air. The recent flight series, which took place at NASA’s Armstrong Flight Research Center in California, was part of the Spanwise Adaptive Wing project, or SAW. This project aims to validate the use …
In simulations, MIT researchers found that tin telluride’s electron characteristics have a significant impact on their mean free paths. They plotted tin telluride’s range of electron energies against the associated mean free paths, and found the resulting graph looked very different than those for most conventional semiconductors. Specifically, for tin telluride and possibly other topological …
Researchers at the University of Twente’s MESA+ research institute have made significant efficiency improvements to the technology used to generate solar fuels. This involves the direct conversion of energy from sunlight into a usable fuel (in this case, hydrogen). Using only earth-abundant materials, they developed the most efficient conversion method to date. The trick was …
Researchers at the University of Bristol have been able to levitate objects using ultrasonic waves larger than the wavelengths of sound used by the device. This could enable touchless control of drug capsules or micro-surgical implements inside the human body using sound. Above – A styrofoam particle of 1.6cm (1.88 wavelengths of sound) trapped in …
