Status of the UC-Berkeley SETI Efforts
We summarize radio and optical SETI programs based at the University of California, Berkeley. The SEVENDIP optical pulse search looks for ns time scale pulses at visible wavelengths. It utilizes an automated 30 inch telescope, three ultra fast photo multiplier tubes and a coincidence detector. The target list includes F, G, K and M stars, globular cluster and galaxies. The ongoing SERENDIP V.v ...
متن کاملSYNTHESIS AND MAGNETIC CHARACTERIZATION OF THE COPPER(I1) DIMER DI-p- (S UB STITUTED PHENOXO) B IS- [(2,2,6,6-TETRAMETHY L HEPTANE-3 ,5- DIONATO) COPPER(II)]
A number of complexes in the series (Cu LL'),, where L = [(CH,),C-CO-CH-COC( CH,),]-I and L'= 3-(Me) C6H,0-, 2,6-(Di-Me)C6H30-, 4-(OH)C6H?O-, 3- (F) C6H,0-, 4-(Br)C6H40-a, nd 3,s-(Dl-Me)C6H30h- ave been prepared and theu magnetic and optical properties determined. In chloroform, the complexes exhibit two bands in the visible and near UV regions. All complexes show room temperature magnetic ...
متن کاملSynthesis and characterization of visible light active S-doped TiO2 nanophotocatalyst
S-doped and bare mesoporous TiO2 were prepared using titanium tetraisopropoxide and thiocarbamide as raw materials. Prepared materials were characterized by means of fourier transform infrared spectroscopy FT-IR, thermogravimetry-differential scanning calorimetry (TG-DSC), X-ray diffraction (XRD), UV–Vis absorption spectroscopy, Brunauer–Emmett–Teller (BET) specific surface area and Barrett–Joy...
متن کاملFabrication and Characterization of Visible Light active Fe-TiO2 Nanocomposites as Nanophotocatalyst
In this research Fe-TiO2 nanocomposites with different molar ratios of Fe/Ti were prepared as nano-photocatalyst using a modified Sol-Gel process at ambient temperature. Crystallographic properties of nanocomposites were characterized by X-ray Diffraction (XRD). Surface morphology and mean particle size of nanocomposites were specified by Field Emission Scann...
