Kinetic roughening transition and missing regime transition of melt crystallized polybutene-1 tetragonal phase: growth kinetics analysis

The morphology and lateral growth rate of isotactic polybutene-1 (it-PB1) have been investigated for crystallization from the melt over a wide range of crystallization temperatures from 50 to 110°C. The morphology of it-PB1 crystals is a rounded shape at crystallization temperatures lower than 85°C, while lamellar single crystals possess faceted morphology at higher crystallization temperatures. The kinetic roughening transition occurs around 85°C. The nucleation and growth mechanism for crystallization does not work below 85°C, since the growth face is rough. However, the growth rate shows the supercooling dependence derived from the nucleation and growth mechanism. The nucleation theory seems still to work even for rough surface growth. Possible mechanisms for the crystal growth of this polymer are discussed.     

The metal-incorporated mesoporous carbon with high performance in capture and degradation of volatile nitrosamines

A new attempt to make novel catalysts for environment protection is reported in this article. The mesoporous carbon with disordered structure is prepared using SBA-15 silica as the hard template and the P123 micelles colluded in the channel as the carbon precursor in one-pot synthesis. To develop the composite of metal-incorporated mesoporous carbon, the metal salt such as ferric sulfate is also utilized as the additive in the synthetic process, resulting in the disordered mesoporous carbon to contain metal species such as α-Fe. Compared with the order mesoporous carbon and the silica/carbon hybrid materials, the disordered mesoporous carbon possesses a good adsorption ability of volatile nitrosamines along with an excellent catalytic activity in the degradation of nitrosamines.
