Environmental UV-A Level Monitoring Using an Ag-TiO<sub>2</sub> Schottky Diode

Here, we demonstrate the field applicability of the Ag-TiO2 Schottky diodes for environmental UV level measurements. The device is visible-blind and it is shown that its maximum sensitivity coincides the environmental UV spectrum (UV-A). These features, along with its low voltage and biasing insensitivity of its operation, simplify the electronic circuit required for the fabrication of a hand-held UV monitoring system.</jats:p

Investigating the forced convection of magnetic nanofluids

Experimental study of the magnetic nanofluids forced convection in a constant magnetic field was carried out. Dependence study of the magnetic nanofluid heat transfer coefficient on the effect of a constant magnetic field was made. The effect of a constant magnetic field on the pressure drop during the magnetic nanofluid flow was shown
