The mode of action of three types of conjugated enamine compounds was investigated by means of thermoluminescence measurement. Cyanoacrylate and 2-(l-ethoxyethylam inom ethylidene)-4-dodecyl-5,5-dim ethyl-cyclohexane-l,3-dione (A C m l2 ) converted the B-band (30 °C) arising from S2Q | charge recombination to a downshifted 6 °C-band. This band was proved to be identical with the DCM U-induced Q...

Immobilization of TiO2 on silica gel has been proposed to enable easy separation of the catalyst in aqueous systems after photocatalytic reaction. Our simple synthesizing method reduces production cost, and the photocatalyst could find economical application in wastewater treatment. Silica-supported TiO2 composites were prepared by molten salt method at 500, 600 and 700 °C for 60 min. The obtai...

Due to insufficient Radio Navigation Satellite Service (RNSS) portion of Radio Frequency (RF) spectrum for many services that are being planned for the future on L band where has come up a frequency overlapping situation, C band as an alternative spectral allocation has already been proposed in the previous years. The future C band signals could make use of the frequency band between 5010MHz an...
