Physical properties of microcellular polymeric foams with supercritical CO2

Abstract This paper mainly introduces the technology of supercritical CO2 pretreatment and high temperature steam preparation of super mild foaming TPU pellets. Mainly discusses the supercritical CO2 pretreatment preparation ultra mild foaming TPU pellets process in high temperature steam condition change of TPU micro foaming granule structure and properties of impact. Experimental results show that the high temperature steam temperature, processing time will influence TPU granules of microporous quantity, structure, resulting in pellets of different physical properties.

Ap Stars

The Ap stars are numerous - the photometric systems tool It would be very tedious to review in detail all that which is in the literature concerning the photometry of the Ap stars. In my opinion it is necessary to examine the problem of the photometric properties of the Ap stars by considering first of all the possibility of deriving some physical properties for the Ap stars, or of detecting new ones. My talk today is prepared in this spirit. The classification by means of photoelectric photometric systems is at the present time very well established for many systems, such as UBV, uvbyβ, Vilnius, Geneva and DDO systems. Details and methods of classification can be found in Golay (1974) or in the proceedings of the Albany Colloquium edited by Philip and Hayes (1975).

The bullet-shaped viruses are currently classified together on the basis of similarities in virion morphology and physical properties. Biologically and ecologically the member viruses are extremely diverse. In searching for further bases for making comparisons of these agents, the nature of host cell infection, both in vivo and in cultured cells, has been explored by thin-section electron microscopy.
