3D printed conductors inside 3D printed solids offer little resistance

Engineers at Rutgers University are claiming 11.8μΩ.cm for conductors printed inside plastic structures, created by printing a novel silver ink and exposing it to high intensity light. The ink has both silver nano-wires and silver nano-spheres within it. These are fused using ‘intense pulsed light sintering’ with a xenon lamp, that is brief enough not to ...

Inorganic perovkite solar cell lasts longer

Perovskite solar cells can be made in open air and “last for months rather than days with a solar conversion efficiency slightly above 12%” according to Rice University if some of the Pb is replaced with indium. The switch also reduces defects that skew the cell’s bandgap. “From our perspective, this is something new and ...

Laser hacks hacks smart-speaker from 100m, opens house doors

University researchers have remotely gained control of a home smart speaker using a laser. The hack worked at a range of 110m, and would have been further if the team had had more space. All that was needed was a 5mW laser (little more than pointer-power) and a telescope (actually a telephoto lens). 60mW was sufficient ...
