Abstract: A ventilation unit is for ventilating an indoor space, and incorporates an air cleaning device and mechanical restrictor for controlling a restriction to a flow resulting from a pressure differential across the unit. There is determination of the inside and outside air pressures in the vicinity of the unit and of air quality parameters inside and outside. The air cleaning device and the mechanical restrictor are controlled in dependence on the determined air pressures and air quality parameters. This provides a fan-less, and hence low-power ventilation unit, which relies on throttling the natural air flow across the unit to provide flow control, and hence enable control of air quality. The air cleaning device may be operated only when the flow is into the inside space, saving power.

Abstract: A particle sensing system is for sensing particles entrained in a fluid. The system comprises a flow channel having a longitudinal direction along which the fluid is to be passed, a heating arrangement for heating the fluid and thereby applying a positive thermophoretic force on the fluid in a direction perpendicular to the longitudinal direction of the flow channel and a first sensor for sensing the particles in the fluid after heating by the heating arrangement. The thermophoretic force increases the concentration of the particles at the first sensor.

Abstract: An improved scintillator nanocomposite comprising nanoparticles with scintillating properties and a diameter between 10 and 50 nanometer and a first matrix material comprises is obtained by introducing the nanoparticles into a dispersing medium to form a stable suspension. The dispersing medium is a precursor to the first matrix material, which is cured to form the first matrix material.
