The technology relates to a new generation of telecommunications and data processing technology with improved wavelength sensitivity in the visible and near-infrared wavelengths range rather than microwave communication in 2–4 GHz. The technology provides the realisation of optical sources (LEDs)

Coarse particle transportation is essential for moving slurries, or fluids containing very high concentrations of pulverised solids, for example, hydraulic transport of coal ore or waste materials. Due to a scarcity of water and a high concentration of the solid particles, pipe blockages are common
