Initial Shock Waves for Explosive Nucleosynthesis in Type II Supernova
We have performed 1-dimensional calculations for explosive nucleosynthesis in collapse-driven supernova and investigated its sensitivity to the initial form of the shock wave. We have found the tendency that the peak temperature becomes higher around the mass cut if the input energy is injected more in the form of kinetic energy rather than internal energy. Then, the mass cut becomes larger, an...
متن کاملFluorescent nanoscale zinc(II)-carboxylate coordination polymers for explosive sensingw
Chemical sensors for rapid detection of explosives are important for the versatile applications in security screening, industrial process control, and environment monitoring. Many explosive compounds possess electron withdrawing nitroaromatic groups, and often act as good electron acceptors. Electron donor conjugated polymers have been seen as one of the most promising candidates for detection ...
متن کاملDetection of Explosive Compounds Using Photosystem II -based Biosensor
The efficacy of a Photosystem II (PS II) -based biosensor for the detection of explosive compounds has been explored. The idea is based on the close similarities in the chemical structures of the widespread explosives and herbicides, with the latter known to inhibit functioning of the PS II by attaching to the binding site of the QB mobile plastoquinone electron acceptor. The gold screen-printe...
متن کاملFluorescent nanoscale zinc(II)-carboxylate coordination polymers for explosive sensing.
Fluorescent nanoscale coordination polymers with cubic morphology and long range ordered structure were fabricated and exhibited efficient sensing for both nitroaromatic explosive and nitromethane due to large surface area to volume ratio and strong binding affinity to explosive molecules.
متن کاملExplosive Nucleosynthesis in Axisymmetrically Deformed Type II Supernovae
Explosive nucleosynthesis under the axisymmetric explosion in Type II supernova has been performed by means of two dimensional hydrodynamical calculations. We have compared the results with the observations of SN 1987A. Our chief findings are as follows: (1) Ti is synthesized so much as to explain the tail of the bolometric light curve of SN 1987A. We think this is because the alpha-rich freeze...
