Raspberry Pi OS, the custom operating system for Raspberry Pis, has had a major upgrade. It is now based on Debian Bullseye, Linux which has replaced two year old Debian Buster. “Debian Bullseye has relatively few major changes which are visible to users,” according to Raspberry Pi. “There are some under-the-hood changes to file systems ...

Electro-spun fibres are a promising candidate for cloth-based tribo-electric nanogenerators (TENGs) according to the University of Fukui. Electro-spinning involves drawing solutions of polymers into fibres using electrical charge. The researchers have developed an all-fibre composite layer TENG that can be integrated with normal cloth. “With our work, we are aiming to provide a new point of ...

A drop of metal that is liquid at just above room temperature can be used as a pump in microfluidics, according to researchers at the University of New South Wales Sydney. Gallium and gallium alloys are suitable. These “are attractive materials due to their unique electrical, thermal and fluidic properties,” according to the university. They ...

Enginees at Lancaster University have transmitted, received and decoded data sent over a fast neutron stream. The proof-of-concept involved modulating neutrons from a calfornium 252 source using an Arduino-controlled mechanical shutter built from high-density polythene. Detection involved a one litre tank of scintillating meterial, a photo-multiplier and a ‘mixed-field analyser’ (made by Hybrid Instruments, based at ...
