Headline: Cutting edge transistors for semiconductors of the future

■ Release Date: 2023.7.3

■ Published by: Lund University

■ Keywords: silicon, semiconductor, transistor

■ Abstract:

Transistors that can change properties are important elements in the development of tomorrow's semiconductors. With standard transistors approaching the limit for how small they can be, having more functions on the same number of units becomes increasingly important in enabling the development of small, energy-efficient circuits for improved memory and more powerful computers. Researchers have shown how to create new configurable transistors and exert control on a new, more precise level.

Headline: How mercury emissions from industry can be greatly reduced

■ Release Date: 2023.7.4

■ Published by: Chalmers University of Technology

■ Keywords: mercury, sulphuric acid, heavy metals

■ Abstract:

Sulphuric acid is the world's most used chemical. It is an important reagent used in many industries and it is used in the manufacture of everything from paper, pharmaceuticals and cosmetics to batteries, detergents and fertilizers. It is therefore a worldwide challenge that sulphuric acid often contains one of the most toxic substances -- mercury. Researchers have now developed a method that can reduce the levels of mercury in sulphuric acid by more than 90 per cent -- even from low levels.

Headline: Nanosheet technology developed to boost energy storage dielectric capacitors

■ Release Date: 2023.7.4

■ Published by: Nagoya University

■ Keywords: capacitor, energy storage, renewable energy

■ Abstract:

A research group has used nanosheet technology to develop a dielectric capacitor for advanced electronic and electrical power systems. Innovations in energy storage technology are vital for the effective use of renewable energy and the mass production of electric vehicles. The capacitor has the highest energy storage density recorded. It has a short charging time, high output, long life, and high temperature stability, making it a major advancement in technology.

Headline: Growing bio-inspired polymer brains for artificial neural networks

■ Release Date: 2023.7.5

■ Published by: Osaka University

■ Keywords: electrode, precursor, polymer

■ Abstract:

A new method for connecting neurons in neuromorphic wetware has been developed. The wetware comprises conductive polymer wires grown in a three-dimensional configuration, done by applying square-wave voltage to electrodes submerged in a precursor solution. The voltage can modify wire conductance, allowing the network to be trained. This fabricated network is able to perform unsupervised Hebbian learning and spike-based learning.

Headline: Researchers create highly conductive metallic gel for 3D printing

■ Release Date: 2023.7.5

■ Published by: North Carolina State University

■ Keywords: copper, indium, gallium

■ Abstract:

Researchers have developed a metallic gel that is highly electrically conductive and can be used to print three-dimensional (3D) solid objects at room temperature.

Headline: Sweat it out: Novel wearable biosensor for monitoring sweat electrolytes for use in healthcare and sports

■ Release Date: 2023.7.6

■ Published by: Tokyo University of Science

■ Keywords: sensor, electrolyte, electrochemical

■ Abstract:

Wearable sensors are becoming a promising tool in personalized healthcare and exercise monitoring. In a recent study, researchers develop a novel wearable chemical sensor capable of measuring the concentration of chloride ions in sweat. By using a heat-transfer printing technique, the proposed sensor can be applied to the outer surface of common textiles to prevent skin irritation and allergies, and could also be useful in the early detection of heat stroke and dehydration.

Headline: Public support hydrogen and biofuels to decarbonize global shipping

■ Release Date: 2023.7.6

■ Published by: University of Southampton

■ Keywords: hydrogen, biofuels, nuclear

■ Abstract:

New research into public attitudes towards alternative shipping fuels shows public backing for biofuel and hydrogen. The study also found that nuclear was preferred to the heavy fuel oil (HFO) currently used in the global shipping industry, although both were perceived negatively. Ammonia had the least public support.

Headline: Researchers grow precise arrays of nanoLEDs

■ Release Date: 2023.7.6

■ Published by: Massachusetts Institute of Technology

■ Keywords: perovskite, halide, solar cells

■ Abstract:

A new platform enables researchers to 'grow' halide perovskite nanocrystals with precise control over the location and size of each individual crystal, integrating them into nanoscale light-emitting diodes.
