Flower-like zinc oxide nanorod clusters grown on spherical cellulose nanocrystals via simple chemical precipitation method
A facile chemical precipitation approach is presented to fabricate flower-like zinc oxide (ZnO) nanorod clusters by using spherical cellulose nanocrystals (SCNs, with cellulose II crystal structure) as growth substrate. Field-emission scanning electron microscopy results showed that nanohybrids (A-100/11) with flower-like ZnO nanorod clusters could be formed under strongly alkaline (pH 11) conditi...

154. Synthesis of Structure-Controlled Polyborosiloxanes and Investigation on Their Viscoelastic Response to Molecular Mass of Polydimethylsiloxane Triggered by Both Chemical and Physical Interactions
A series of polyborosiloxanes (PBSs) was synthesized by mixing hydroxy-terminated polydimethylsiloxanes (PDMS) and boric acid (BA) in toluene at 120 °C. The molecular masses of selected PDMS precursors were in a wide range, covering from below up to far above the critical entanglement molecular mass of PDMS. The reaction kinetics was followed by using Fourier transform infrared (FTIR) spectrosc...

[Physical Chemistry Chemical Physics] Magnetoresistive Polyaniline-Silicon Carbide Metacomposites: Plasma Frequency Determination and High Magnetic Field Sensitivity
The Drude model modified by Debye relaxation time was introduced to determine the plasma frequency (ωp) in the surface initiated polymerization (SIP) synthesized β-silicon carbide (β-SiC)/polyaniline (PANI) metacomposites. The calculated plasma frequency for these metacomposites with different loadings of β-SiC nanoparticles was ranging from 6.11 × 104 to 1.53 × 105 rad s?1. The ...

POSS-based molecular hybrids with low dielectric constant: Effect of chemical structure and molecular architecture
Three kinds of hybrids with different architectures including dumbbell-type, bead-type, and cross-linked structure, were prepared via the Heck reaction between octavinyl-polyhedral oligomeric silsesquioxane (OV-POSS) and different bromo-substituted aromatic amide monomers. The molecular architecture can be successfully achieved by simply varying the feed ratio of OV-POSS to monome...

(Chemical Science) A calamitic mesogenic near-infrared absorbing croconaine dye/liquid crystalline elastomer composite
In this work, we report the first example of a calamitic mesogenic near-infrared (NIR) absorbing organic dye,
made by functionalizing a thiophene–croconaine chromophore rigid core with two symmetric long flexible
alkyl chains. The liquid crystal (LC) NIR dye YHD796 exhibits a sharp and intense NIR absorption band with
a maximum absorption peak at 796 nm. Taking advantage of the improve...

【Chemical Communications】Facile fabrication of microsphere-polymer brush hierarchically three-dimensional (3d) substrates for immunoassays
Abstract:
We propose a facile UV strategy to construct a hierarchically three-dimensional (3D) substrate that comprises a polystyrene (PS) microsphere layer on the cycloolefin polymer (COP) substrate and densely packed hydrophilic polymer brushes grafting from this 3D backbone. This hierarchical substrate gives a high antibody loading capacity and 3D manner of analyte capture, therefore enhan...

Tailoring the chemical composition and dispersion behavior of fluorinated graphene oxide via CF4 plasma
Grafting fluorine onto graphene oxide (GO) by CF4 plasma treatment was investigated in this study. An easy, low-cost, and effective synthesis of the high-dispersive fluorinated GO (FGO) with tunable atomic ratio of F/O (RF/O) has been realized and the RF/O can be readily manipulated just by adjusting the reaction time. The influence of plasma treatment time on the microstructure, morphology, and d...

Soft Matter, 2011, 7, 8932-8941; Chemical modification of bioinspired superhydrophobic polystyrene surfaces to control cell attachment/proliferation
Surface chemistry is known to have a profound influence on cellular behavior. However, the cells'' responses on surfaces exhibiting extreme wettability values are not yet fully understood. In this work, bioinspired superhydrophobic polystyrene (PS) surfaces were produced by a phase separation method and the in vitro performance of three different cell lines (SaOs-2, L929 and ATDC5) was...
