LuxLive: Lumileds purple LED spotted
Lumileds revealed a purple LED at LuxLive in London yesterday. Part of its Luxeon C Colors range, the firm has added a red phosphor to a blue die to produce the lamp, which is intended for plant growing – where green light is wasted in reflection. The colour can be seen on the far right ...
LuxLive: Marl, Nanoco deliver world-first nano-particle luminaires
The world’s first nano-particle LED lighting products have come from a deal between Cumbria LED lighting firm Marl and Nanoco of Manchester. Revealed at LuxLive in London last week, nano-particles will allow luminaires with precisely-tuned spectra to be made – for example lighting for plant growth. Photon for photon, they are not quite as efficient ...
Pop rivet tool gets higher power to weight ratio
Pop Avdel has introduced a blind rivet nut installation tool for production lines. Fast cycling (<1.5s per setting) and high force-to-weight ratio (11.1kN/kg) are claimed for the air-powered tool, called ProSert XTN20. Blind rivet nuts from M3 to M10 (see XTN20 manual for restrictions) can be placed with the 1.59kg (M6 nose piece) XTN20 using air ...

Microchip adds algorithms to automatic C code generation tool
Microchip has added application algorithms to the register initialisation function already available in its Code Configurator automatic C code generation tool. Currently available for comment as a ‘beta’ release, Code Configurator version 3.0 will automatically implement code for functions including capacitive touch, a boot-loader, and a TCP/IP stack. “If you wanted to implement a touch ...

Tuneable UHF stealth coating is only 8mm thick
Chinese researchers have produced an active stealth coating to reduce UHF radar reflections. It can reduce reflections to better than -10dB over 7ooMHz to 1.9GHz, despite being only 1/29 of a wavelength thick at the centre frequency. Conventional absorbers for the ultra-high regime are usually thick, heavy or have narrow absorption bandwidth, making them unsuitable ...

1D organic semiconductor complement 2D graphene
Graphene famously only conducts in two dimensions. Now scientists in Germany have found layered materials that only conduct in the other dimension: perpendicular to its flat sheets. Called polymeric carbon nitrides, the crystalline structure resembles that of graphite because the carbon nitride groups are chemically bound only in layers, while only weak Van der Waals forces ...
