Palladium nanoparticles (PdNp) were revealed as an efficient hydrogen isotope exchange catalyst for the deuterium and tritium labeling of benzylic positions complex molecules. A practical way to obtain small palladium apply them a (HIE) is presented. Several model compounds popular bioactive molecules submitted HIE reactions catalyzed by PdNp.

We report initial results of exposing low-Z solid and high-Z liquid targets to 150-ns, 4/spl times/10/sup 12/ proton pulses with spot sizes on the order 1 2 mm. The energy deposition density approached 100 J/g. Diagnostics included fiberoptic strain sensors target high-speed photography targets.

Fast neutron imaging has a great potential as nondestructive technique for testing large objects. The main factor limiting applications of this is detection technology, offering relatively poor spatial resolution images and low efficiency, which results in very long exposure times. Therefore, research on development scintillators fast high importance. A comparison the light output, gamma radiation sensitivity commercially available scintillator screens composed PP/ZnS:Cu PP/ZnS:Ag different...
