As the River Thames meanders eastward through London, it horseshoes around a lobe of land called the Isle of Dogs. In the 19th century, the area boasted one of the world’s busiest dock complexes, but by 1980 it had deteriorated into an industrial wasteland. More recently, thanks to massive redevelopment, the area has blossomed again to become Canary Wharf, an enclave of glittering glass skyscrapers that is now a global financial center. And here, in the murky waters of the North Dock, sits one of the largest and sleekest stations in London’s newest railway: Crossrail.

Hydrogen Helps Make Topological Insulators Practical

This trick could open a path toward practical quantum computing and dissipationless electronics

In this image, a beaker of hydrochloric acid (HCl) contains an enlarged model of a submerged sample of a topological insulator. Hydrogen atoms from the HCl [blue dots] bind to the insulator [red and white circles], in the process retaining the insulator’s useful electronic properties while also becoming stable at room temperature.

Future microchips that require far less energy than present-day devices may rely on exotic materials known as topological insulators, in which electricity flows across only surfaces and edges, with virtually no dissipation of energy. However, it can prove tricky developing such materials for real-world applications. Now a new study reveals that simply incorporating hydrogen into topological insulators may control their electronic properties to help make them useful.

Topology is the branch of mathematics that investigates what features of shapes may survive deformation. Material science has emerged in recent decades as an unexpected but compelling application of topology. The insights from topological models, scientists have discovered, help to understand and predict some materials’ unusual properties. These include electromagnetic effects beyond those explained by Maxwell’s Equations as well as quantum particles that could yield new kinds of electronic and optical devices.

Achieving the next level in vehicle autonomy demands robust algorithms trained to interpret radar reflections from automotive radar sensors. Overcome the gaps between software simulation and roadway testing to train the ADAS / AV algorithms with real-world conditions. Sharpen your ADAS' radar vision with full-scene emulation that allows you to lab test complex real-world scenario, while emulating up to 512 objects at distances as close as 1.5 meters.
