Moiré patterns occur everywhere. They are created by layering two similar but not identical geometric designs. A common example is the pattern that sometimes emerges when viewing a chain-link fence through a second chain-link fence.

For more than 10 years, scientists have been experimenting with the moiré pattern that emerges when a sheet of graphene is placed between two sheets of boron nitride. The resulting moiré pattern has shown tantalizing effects that could vastly improve semiconductor chips that are used to power everything from computers to cars.

A new study led by University at Buffalo researchers, and published in Nature Communications, demonstrated that graphene can live up to its promise in this context.

Musk warned of “stormy weather” ahead, flagged Tesla’s key challenges, and touted its Dojo supercomputer and autonomous driving tech as revolutionary.

In a project commissioned by the New Energy and Industrial Technology Development Organization (NEDO), researchers at Nagoya University in Japan have developed poly(styrenesulfonic acid)-based PEMs with a high density of sulfonic acid groups.

One of the key components of environmentally friendly polymer electrolyte fuel cells is a polymer electrolyte membrane (PEM). It generates electrical energy through a reaction between hydrogen and oxygen gases. Examples of practical fuel cells include fuel cell vehicles (FCVs) and fuel cell combined heat and power (CHP) systems.

The best-known PEM is a membrane based on a perfluorosulfonic acid polymer, such as Nafion, which was developed by DuPont in the 1960s. It has a good proton conductivity of 0.1 S/cm at 70–90 °C under humidified conditions. Under these conditions, protons can be released from sulfonic acid groups.

Flying across the world from Europe to Australia currently takes around 20 hours in a regular passenger jet.

But Swiss startup Destinus is looking to slash that time to just four hours — by taking jet travel to hypersonic speeds.

Founded by Russian-born physicist and serial entrepreneur Mikhail Kokorich, Destinus is developing a prototype hydrogen-powered aircraft capable of travelling at Mach 5 and above. That’s five times the speed of sound: over 6,000 kph.

The earliest artificial neural network, the Perceptron, was introduced approximately 65 years ago and consisted of just one layer. However, to address solutions for more complex classification tasks, more advanced neural network architectures consisting of numerous feedforward (consecutive) layers were later introduced. This is the essential component of the current implementation of deep learning algorithms. It improves the performance of analytical and physical tasks without human intervention, and lies behind everyday automation products such as the emerging technologies for self-driving cars and autonomous chat bots.

The key question driving new research published today in Scientific Reports is whether efficient learning of non-trivial classification tasks can be achieved using brain-inspired shallow feedforward networks, while potentially requiring less computational complexity.

“This is to a jet ski what a hypercar is to a car,” said its designer. Sculpted in carbon fiber, the Supermarine MM01 has a 75 mph top end.

When used at home, it might take care of your yard, and even your grandparents, as Musk suggests in his piece, Believing in technology for a better future, in the Cyberspace Administration of China’s publication:

Tesla Bots are initially positioned to replace people in repetitive, boring, and dangerous tasks. But the vision is for them to serve millions of households, such as cooking, mowing lawns, and caring for the elderly.

The energy per unit mass of 500 Wh/kg is twice that of typical Li-ion batteries. In addition to doubling the range of EVs, this could enable longer-haul electrified aviation.

Contemporary Amperex Technology Co., Limited (CATL) has today launched a new ‘condensed battery’ with up to 500 Wh/kg. This ultra-high energy density could enable the electrification of passenger aircraft.
