Graphene-based electrode prototype, inspired by fern leaves, could be the answer to solar energy storage challenge. Inspired by an American fern, researchers have developed a groundbreaking prototype that could be the answer to the storage challenge still holding solar back as a total energy solution. The new type of electrode created by researchers from RMIT University in Melbourne, Australia, could boost the capacity of existing integrable storage technologies by 3000%.

But the graphene-based prototype also opens a new path to the development of flexible ...

Quantum Communication: How to Outwit noise

Sketch of a thermal quantum network, where two nodes (for example, two superconducting qubits located inside separated dilution refrigerators) are connected via a unidirectional quantum communication channel at finite temperature T ch . (b) For the implementation of a noise-resilient transfer protocol, the qubit state is first mapped onto an intermediary oscillator. The oscillator is then coupled to the incoming and outgoing fields of the channel, f in , i ( t ) and f out , i ( t ) , via a tunable decay rate γ i ( t ) , which can be realized, for example, by a flux-tunable quantum interference device [45, 46, 47].

A team of engineering researchers has made a fundamental advance in controlling so-called soft robots, using magnetic fields to remotely manipulate microparticle chains embedded in soft robotic devices. The researchers have already created several devices that make use of the new technique. “By putting these self-assembling chains into soft robots, we are able to have them perform more complex functions while still retaining relatively simple designs,” says A/Prof Joe Tracy, North Carolina State University ...

Engineers have installed 2 test slabs of electrically conductive concrete and the pavement has effectively cleared ice and snow. Iowa State University’s Halil Ceylan picked up his smartphone, opened up an app and called up the remote controls for the first full-scale test slabs. When a winter storm approaches, Ceylan can use that app to turn on the heated pavement system and, thanks to real-time video capability, watch as snow and ice melts away.
