Reversible addition−fragmentation chain transfer (RAFT) aqueous dispersion polymerization was used to synthesize a novel type of core−shell nanogel containing linear poly(ethylene glycol) (PEG) and/or nonlinear polymers with oligo(ethylene side chains. These nanogels low polydispersities were synthesized efficiently tunable sizes and thermosensitivities. The chains as the shell had enhanced stability during freeze−thawing process in biologically relevant solutions including 1.5 M NaCl, 1%...
Aqueous dispersion polymerization systems mediated by reversible addition–fragmentation chain transfer (RAFT) process have been less studied in comparison with other heterogeneous due to limited number of monomer/polymer pairs that are suitable for such a condition. We report novel system based on 2-methoxyethyl acrylate (MEA) which is highly water-soluble, but its polymer not. Using hydrophilic polymer, poly(poly(ethylene glycol) methyl ether methacrylate) (PPEGMA), as the macromolecular...
Thermosensitive polymeric materials based on copolymers of oligo(ethylene glycol) methacrylates are attracting significant attention in various sectors. The preparation their thermosensitive microgels/nanogels via the aqueous dispersion polymerization process is, however, limited by low monomer loading and thus solid content final colloids. Moreover, nanogels reversible addition-fragmentation chain transfer (RAFT) mediated has been further hampered poor RAFT control process. In this article,...
In situ cross-linking of nano-objects with controllable morphologies in polymerization-induced self-assembly (PISA) has been a challenge because lowers chain mobility and hence inhibits morphology transition. Herein, we propose novel strategy that allows vesicles PISA an aqueous dispersion polymerization formulation. This is realized by utilizing asymmetric cross-linker bearing two vinyl groups differing reactivities such delayed to the late stage when transition completed. Cross-linked...

In this paper, a comprehensive study of millimeterwave (mmW) imaging for far-field and near-field objects using 1-bit programmable metasurface (PMS) is presented. Theoretical PMS simulation models are proposed by plane-wave angular spectrum approach, in which two based on the flexible mmW beam-forming developed.

Electron-diffraction and high-resolution lattice images reveal superstructure stripes with wave vectors of (1/3, 0, 1/3) (-1/3, 1/3), which are associated the ordered arrangement F(-). Charge density distribution suggests that these manifest themselves electronically as F(-)-Cr(3+)-F(-) zigzag chains, driven by anisotropic charge interaction F(-) anions.
