We’re releasing an analysis showing that since 2012 the amount of compute needed to train a neural net to the same performance on ImageNet classification has been decreasing by a factor of 2 every 16 months. Compared to 2012, it now takes 44 times less compute to train a neural network to the level of AlexNet (by contrast, Moore’s Law would yield an 11x cost improvement over this period). Our results suggest that for AI tasks with high levels of recent investment, algorithmic progress has yielded more gains than classical

Shin-Etsu Chemical Co., Ltd. (Head Office: Tokyo; President: Yasuhiko Saitoh) is launching a number of new products in order to take advantage of surging demand for highly advanced materials in the coming 5G era (Fifth Generation Telecommunication). Shin-Etsu has newly developed a “Quartz Cloth” and a “Thermoset Ultra-low Dielectric Resin” ideal for electronics devices, printed circuit boards, IC substrates, antennas, and radar domes that will be used in 5G high-frequency (including millimeter-wave) communication. Furthermore, we are expanding our lineup of heat dissipation products. In connection with these newly developed products,

Single-walled CNTs have several attributes that make them well-suited for sensing processes that involve the transfer of electrons – the basis of any chemical reaction. The CNTs Fong and Swager and their colleagues worked with are p-type semiconductors, so n-type dopants – anything that donates electrons to the CNT – will diminish their conductivity. The CNTs’ curved graphene surface

Telltale sign: Carbon nanotubes detect ethylene through the presence of Pd(0) produced during the Wacker reaction. (Courtesy: Darryl Fong) When one bad apple rots the bunch, it’s ethylene’s fault. Not only does this “universal plant hormone” trigger germination, flowering, ripening and rotting in seeds, flowers, fruit and vegetables, it’s also released during these processes, ensuring that a small problem quickly escalates. Ethylene is social media for plants, allowing them to communicate and synchronize – and it’s something the food and flowers industries would love to detect early, so they can

It’s the most complex integration of carbon nanotube-based CMOS logic so far, with nearly 15,000 transistors, and it was done using technologies that have already been proven to work in a commercial chip-manufacturing facility.

Quantum dots coated on a transparent substrate with gold contacts for mid-infrared detection. ©ICFO Optical sensors that work in the mid- to long infrared part of the electromagnetic spectrum have a host of applications, including gas sensing, thermal imaging and detecting hazards in the environment. Such sensors are, however, costly and based on toxic mercury-containing compounds or epitaxial quantum-wells or quantum-dot infrared photodetectors that are difficult and time-consuming to fabricate. Researchers at the Institute of Photonic Sciences in Spain have now overcome these flaws by constructing a mercury-free colloidal quantum

Protons penetrating the graphene film grown on copper. Courtesy: L Gao A new technique to make ultra-flat, wrinkle-free films of graphene could pave the way for a host of applications, including graphene-based flexible electronics and high-frequency transistors. The technique works by introducing protons into the film as graphene is synthesized using chemical vapour deposition (CVD), and its inventors say that it might be extended to other two-dimensional materials such hexagonal boron nitride (h-BN) and the transition-metal dichalcogenides (TMDCs). It could also aid the development of hydrogen storage devices made from
