The thermo-oxidative decomposition behavior of PP/MWCNT and stabilizing effect caused by addition of MWCNT has been investigated by means of TGA and EPR spectroscopy.

Studies of thermal and fire-resistant properties of the polypropylene/multi-walled carbon nanotube composites (PP/MWCNT) prepared by means of melt intercalation are discussed. The sets of the data ...acquired with the aid of non-isothermal TG experiments have been treated by the model kinetic analysis. The thermal-oxidative degradation behavior of PP/MWCNT and stabilizing effect caused by addition of MWCNT has been investigated by means of TGA and EPR spectroscopy. The results of cone calorimetric tests lead to the conclusion that char formation plays a key role in the mechanism of flame retardation for nanocomposites. This could be explained by the specific antioxidant properties and high thermal conductivity of MWCNT which determine high-performance carbonization during thermal degradation process. Comparative analysis of the flammability characteristics for PP-clay/MWCNT nanocomposites was provided in order to emphasize the specific behavior of the nanocomposites under high-temperature tests.

The Baikal Neutrino Telescope has been operating in its NT200 configuration since April, 1998. The telescope has been upgraded in April, 2005 to the 10Mton scale detector NT200+. It's main physics ...goal is the detection of signals from high energy neutrino cascades. NT200+ reaches a 3-year sensitivity of 2×10-7cm-2s-1sr-1GeV for an all-flavor diffuse cosmic E-2 neutrino flux for energies 102TeV–105TeV.
Design and sensitivity of NT200+ are described. NT200+ is forming the basic building block of a future km3-scale (gigaton-volume) Baikal Telescope. Research and development work on that next stage detector has started.
