Opis:: Mid-infrared laser spectroscopy is a powerful analytical tool for trace gases detection. In this study, a spectroscopic system based on an external cavity quantum cascade laser (ECQCL) and quartz enhanced photoacoustic spectroscopy (QEPAS) was developed for volatile organic compounds (VOCs) measurements. Primary laboratory test on ethanol spectroscopy was investigated and compared with traditional direct absorption spectroscopy (DAS). Experimental results show that the proposed QEPAS is more sensitive than the conventional DAS method. In addition, the significant linear dependence of photoacoustic signal on sample pressures and laser operating parameters was observed.

Tytuł:: The Antibacterial Activities of Ag/$Nano-TiO_2$ Modified Silicone Elastomer

Opis:: We studied the ability of Ag/$nano-TiO_2$ to inhibit Staphylococcus aureus growth on silicone elastomer material. Ag/$nano-TiO_2$ silicone elastomer was prepared with different concentrations of 0%, 2%, 4%, 6%, 8%, 10%. The antibacterial efficacy of Ag/$nano-TiO_2$ silicone elastomer was determined by the inhibition zone method and the impregnated culture method. The antibacterial timeliness of Ag/$nano-TiO_2$ silicone elastomer was tested by direct contact method. The samples were kept through thermal aging process in an accelerated aging chamber. The effect of concentrations of Ag/$nano-TiO_2$ was insignificant (P < 0.05). There was significant difference between the Ag/$nano-TiO_2$ silicone elastomer and the blank silicone elastomer (P < 0.5). There was also significant difference among specimen groups whose aging periods were 50°C, 100°C, 150°C, 200°C for 87 h (P < 0.5). The silicone elastomer with different concentrations of Ag/$nano-TiO_2$ effectively inhibits Staphylococcus aureus growth.
