Tiny, potent motor amplifies output via frictionless magnetic gearing

『V』𝚃『B』Casts┋
The race is on to create an ebike motor that adds the least amount of weight and bulk as physically possible, disappearing away into the bike where it's barely seen or heard but is felt on every pedal stroke. The latest contender is the Magnetic Gear Motor (MGM) from Chinese ebike component supplier Star Union. As its name implies, this electric motor drive swaps out physical gears in favor of a magnetic gear system that compacts the core while cutting friction. The drive is then able to put out a serious punch from a tiny, incognito package.

'Squeezed' light might produce breakthroughs in nano-sized electronics

It's one thing to produce nanoscale devices, but it's another to study and improve on them — they're so small they can't reflect enough light to get a good look. A breakthrough might make that possible, however. UC Riverside researchers have built technology that squeezes tungsten lamp light into a 6-nanometer spot at the end of a silver nanowire. That lets scientists produce color imaging at an "unprecedented" level, rather than having to settle for molecular vibrations. The developers modified an existing "superfocusing" tool (already used to measure vibrations) to detect signals across the entire visible spectrum. Light travels in a flashlight-like conical path. When the nanowire's tip passes over an object, the system records that item's influence on the beam shape and color (including through a spectrometer). With two pieces of specrtra for every 6nm pixel, the team can create color photos of carbon nanotubes that would otherwise appear...

Researchers have created a low-lead method to convert CO₂ into solid metal oxalates. Researchers at the University of Michigan have contributed to the development of a method that transforms carbon dioxide, an industrial waste product that contributes to atmospheric pollution, into a valuable material: precursors for cement. U-M chemist Charles McCrory and his research team, [...] http://dlvr.it/TLMbKm
