In this study, we made an attempt to synthesize doped bioactive hydroxyapatite (HAp) ceramic powder using a simple Chemical method and studied its physical and mechanical properties. Different quantities (2wt% and 5 wt%) of Magnesium chloride Hexahydrate , Zinc oxide, Titanium oxide were incorporated as dopants into Hap at the time of synthesis. The synthesized powder samples were analyzed for ...

Tritium-labeling o f the ingenol monoester 3-O-tetradecanoylingenol (3-TI), the prototype tumor promoter o f the ingenane type diterpene esters, is described. The preparation starts with oxidation o f 3-TI by manganese dioxide to yield 3-TI-20-aldehyde which is reduced by [3H]sodium borohydride in the presence o f equimolar amounts o f cerium trichloride hexahydrate to give [20-3H]-3-TI. The la...

A new approach to fast-neutron dosimeq is described. It involves circulating a liquid with dissolved chemicals between a localized neutron field and a remote area where neutron-induced radioactivities are measured continuously. This approach employs reactions whch generate relatively short-lived radioactive byproducts. Sensitivity to the neutron energy spectrum is achieved by choosing several r...

The 62 entries listed in ICSD release 2009/1 under polar space group P31m correspond to 31 families of inorganic crystal structures, some with only one member. Coordinate analysis reveals, over a wide confidence range, 11 of these families as ferroelectric candidates. One includes the well known improper ferroelectric GASH (guanidinium aluminum sulfate hexahydrate), [(C(NH(2))(3))Al(SO(4))(2)(H...

PVDF nanofibers are prepared using electrospinning. The effect of addition of a hydrated salt, nickel chloride hexahydrate (NiCl(2)·6H(2)O), on the phase formation is examined. Addition of the hydrated salt (NC) is found to enhance the polar β phase by about 30%. The peak to peak piezo-voltage generated for PVDF NC is almost 0.762 V, a factor of 3 higher than that for PVDF. The fiber mats exhib...
