Inside a jet engine is one of the most extreme environments known to engineering.
In less than a second, a tonne of air is sucked into the engine, squeezed to a fraction of its normal volume and then passed across hundreds of blades rotating at speeds of up to 10,000 rpm; reaching the combustor, the air is mixed with kerosene and ignited; the resulting gases are about a third as hot as the sun’s surface and hurtle at speeds of almost 1,500 km per hour towards a wall of turbines, where each blade generates power equivalent to the thrust of a Formula One racing car

The technology could also allow able-bodied people to access TV programmes much more quickly and easily, he said. “This is building on work we have done using voice control on consoles like the Xbox One, for example, to get to content as quickly and easily as possible.”

Crystalline semiconductors like silicon can catch photons and convert their energy into electron flows
Discoveries about the causes of stress-corrosion cracking in metal alloys could help prevent failure of critical infrastructure systems such as pipelines that transport water, fossil fuels and natural gas, as well as operating systems for nuclear power generation facilities and the framework of aircraft.
Rapid laser arc deposition method for depositing carbon and tantalum-carbon films creates near-diamond hard, high-thickness coatings that are claimed to have the potential to save billions of litres of fuel
