East Coast Microwave is stocking cryogenic isolators from DiTom Microwave, designed to operate “at or below 77K”, according to East Coast. Taking D3I4080Y as an example, it operates from 4 to 8GHz and can handle average forward inputs up to 30W, peaking at 50W. Maximum reverse input power is 2W. “The component provides more than 16dB of isolation and has ...
While lithium ion cells have many wonderful characteristics, one of the great limitations is that they cannot be charged below 0°C. This statement, it turns out, is slightly glib as there is one Li-ion chemistry that can handle it: lithium titanate, it is usually called. And just a note here: not all lithium titanate cells are so blessed. One manufacturer ...
Scientists at Missouri University of Science and Technology have grown zinc oxide crystals directly on a silicon wafer, potentially widening the absorption spectrum of solar cells. The process involves only low temperature wet chemistry.
London display materials developer OLED-T launches a low-temperature organic electron injector material for organic LED displays.
A detector that can count single photons with 88 per cent efficiency has been demonstrated by physicists at the National Institute of Standard and Technology in the US. The sensor was made from a 25µmx25µmx20nm square of tungsten cooled to 110mK – the temperature at which the metal goes from being a normal conductor to a superconductor. A photon striking ...
