Poly/melamine cyanurate composite latex particles are prepared via soapless emulsion polymerization. XPS data and TGA analysis reveal that MC particles are encapsulated by PMMA during polymerization, resulting in the formation of a core-shell structure of PMMA/MC composite latex particles. MC can affect the thermal degradation and promote the charring of PMMA. The application of PMMA/MC in nylon 6 (PA6) indicate that the composite latex particles can improve the mechanical pro...

The results show that the obtained nanoscale zero valent iron particles are mostly in spherical shape with less than 100 nm in size. The acid fuchsine can be removed by nanoscale zero valent iron particles efficiently. The efficiency of removing acid fuchsine from solution is increased with increasing temperature and the dosage of nanoscale zero valent iron particles and decreasing initial concentration of acid fuchsine. The mechanism of removing acid fuchsine by nanoscale zero valent iron particles may include dual functions of absorption and degradation, and the degradation may play a major role in the reaction.

It is presented that indirect assimilation experiment of CMW data from TCFM method improves effectively not only on vertical velocity field but for precipitation.4 Based on theory analysis, E-Ir relationship is brought forward with two electrification mechanisms. One is inductive mechanism, i.e., cloud particles collide with precipitation particles then flick away, the other is noninductive mechanism because of different temperature, i.e., bigger supercooled cloud particles collide and freeze with hail particles combined with ice scraps. By means of CINRAD and FY2C data assimilation, precipitation intensity Ir can be obtained, then electric field intensity E, discharge time and locations can be achieved with supposed threshold 300KV/m. Though it can not distinguish between IC (Intra-Cloud) lightning and CG (Cloud-to-Ground) lightning, results are still comparable to LLS observations.5 Example analysis shows that the relationship between precipitation data from AMS and CG data from LLS is not very clear.
