In this paper, the synthesis and characterization of thermal properties of porous copolymers 1-vinyl-2-pyrrolidone with trimethylolpropane trimethacrylate are presented. They were obtained by suspension polymerization as a pure polymers or composite materials with different inorganic fillers. The influence of the type of filler on the textural and thermal properties was investigated in details....

The Tibetan Plateau (TP) is known as the Asian water tower that supplies fresh for millions of people in Asia. vortices (TPVs) are one major precipitation-producing weather systems over TP. characteristics TPV-associated precipitation from 1979 to 2017 quantitatively analysed based on three daily datasets. influence TPVs more significant warm season (May–September) because and TPV activities bo...

The present research work describes an efficient method for facile synthesis of α-MnO2 nanorods by hydrothermal method and preparation of a series of polythiophene/manganese dioxide (PTh/MnO2) nanocomposites with various α-MnO2 ratios. These nanocomposites were fabricated by in-situ oxidative polymerization method using FeCl3 as oxidant, and characterized by Fourier transformed infrared (FT-IR)...

The temperature profile (TP) of the intracluster medium (ICM) is of primeval importance for deriving the dynamical parameters of the largest equilibrium systems known in the universe, in particular their total mass profile. Analytical models of the ICM often assume that the ICM is isothermal or parametrize the TP with a polytropic index γp. This parameter is ajusted to observations, but has in ...

this paper reports the synthesis of polypyrrole coated sno2/znoelectrospunnanofibers via vapor phase polymerization method. in order to prepare one dimensional (sno2-zno)/polypyrrole with the core sheath structure, first sno2-zno composite nanofibers were synthesized via electrospinning method followed by adsorption of fe3+ on the surface of the sno2-zno nanofibers and finally pyrrole was polym...

Biobased exo-methylene-conjugated dienes underwent regioselective living cationic polymerization to result in well-defined homo- and copolymers with good thermal properties.

Certain kinds of cellular movements are apparently driven by actin polymerization. Examples include the lamellipodia of spreading and migrating embryonic cells, and the bacterium Listeria monocytogenes, that propels itself through its host's cytoplasm by constructing behind it a polymerized tail of cross-linked actin filaments. Peskin et al. (1993) formulated a model to explain how a polymerizi...
