Optimising defects for better superconducting effects

Optimising defects for better superconducting effects
High-temperature superconducting materials hold enormous promise for a variety of different applications because of their ability to transmit a current without any dissipation at relatively high temperatures—up to around 90 K (about -300°F), which permits cooling with liquid nitrogen. However, this special ability decreases rapidly in the presence of a magnetic field, prohibiting their widespread use in superconducting motors and turbines.

The advent of bacteria-powered microscopic 'windfarms'

The advent of bacteria-powered microscopic 'windfarms'
A team of scientists from Oxford University has shown how the natural movement of bacteria could be harnessed to assemble and power microscopic 'windfarms' - or other human-made micromachines such as smartphone components. The study, published in the journal Science Advances, uses computer simulations to demonstrate that the chaotic swarming effect of dense active matter such as bacteria can be organised to turn cylindrical rotors and provide a steady power source.

Technology recharges smartphones with urine

Technology recharges smartphones with urine
The microbial fuel cell technology, which is also inside the 'Pee Power' urinals developed at the University of the West of England (UWE Bristol), now has the capacity to power up and recharge a smartphone. A world first, the improved system enables three hours of phone operation (outgoing call) for every six hours of charge time, with as little as 600ml (per charge) of urine.

91% efficient switching regulators do not require heat sinks

91% efficient switching regulators do not require heat sinks
RECOM has expanded its low-cost, highly-efficient R-78E switching regulator series with modules featuring 9, 12 and 15V output voltages. This series is designed to offer all of the advantages of a standard switching regulator (high efficiency, wide input range, accurate output voltage regulation) but at a lower cost.

Nano-electronic circuits have superconductivity

Nano-electronic circuits have superconductivity
Scientists at TU Delft, together with colleagues from the Tübingen University, have successfully created nano-electronic circuits using a recently discovered 2D superconductor. What makes this material unique is that its superconductivity can be turned on and off remotely, very much like the switching of electrical current in a transistor on a microchip.
