چکیده
While the synthesis of linear polymers with both ends conserved is severely impeded due to inevitable macrocyclization in step-growth polymerization, this work provides a new idea mainly formation polymer chains.

Preparation of Monodisperse Melamine-Formaldehyde Microspheres via Dispersed Polycondensation
We have successfully synthesized relatively monodisperse and cross-linked melamine-formaldehyde (MF) microspheres by dispersed polycondensation and subsequent pH adjustment with serum replacement cleaning. The average particle sizes ( : weight-average and : number-average), the polydispersity index ( ), the number of particles Np, and the gel content of the M-F microspheres were observed by var...

Molecular dynamics simulations have been carried out to investigate structural and dynamical characteristics of NaCl aqueous solutions confined within silica nanopores in contact with a "bulk-like" reservoir. Two types of pores, with diameters intermediate between 20 Å and 37.5 Å, were investigated: The first one corresponded to hydrophobic cavities, in which the prevailing wall-solution intera...
متن کاملProton quantum coherence observed in water confined in silica nanopores.
Deep inelastic neutron scattering measurements of water confined in nanoporous xerogel powders, with average pore diameters of 24 and 82 A, have been carried out for pore fillings ranging from 76% to nearly full coverage. DINS measurements provide direct information on the momentum distribution n(p) of protons, probing the local structure of the molecular system. The observed scattering is inte...
