The Influence of Ultrasound and Ultraviolet Irradiation on the Nanocomposite Calcium Phosphate-Polymeric Gel

An influence of high-intensive ultrasound and ultraviolet (UV) irradiation on the nanocomposite calcium phosphate-polymeric gels has been investigated. The action of UV light leads to a significant increase in shear stress and viscosity of hydroxyapatite (HA) / polyvinyl alcohol (PVA) gel while HA / sodium carboxymethyl cellulose (Na-CMC) gel is insensitive to the UV action. Ultrasonic treatment of HA / PVA gel plays an important role only at small shear rates. UV treatment of HA / Na-CMC gel has no effect on its structure and can be used for low temperature UV sterilization.

Small-Size Resonant Photoacoustic Cell of Inclined Geometry for Gas Detection

A photoacoustic cell intended for laser detection of trace gases is represented. The cell is adapted so as to enhance the gas-detection performance and, simultaneously, to reduce the cell size. The cell design provides an efficient cancellation of the window background (a parasite response due to absorption of laser beam in the cell windows) and acoustic isolation from the environment for an acoustic resonance of the cell. The useful photoacoustic response from a detected gas, window background and noise are analyzed in demonstration experiments as functions of the modulation frequency for a prototype cell with the internal volume ~ 0.5 cm^3. The minimal detectable absorption for the prototype is estimated to be ~ 1.2 10^{-8} cm^{-1} W Hz^{-1/2}.Comment: 11 pages, 5 figure
