Organic-inorganic hybrid superhydrophobic surfaces using methyltriethoxysilane and tetraethoxysilane sol-gel derived materials in emulsion
By applying alkaline-catalyzed co-hydrolysis and copolycondensation reactions of tetraethoxysilane (TEOS) and methyltriethoxysilane (MTES) in organic siloxane modified polyacrylate emulsion (OSPA emulsion), we are able to demonstrate the potential for developing a sol-gel derived organic-inorganic hybrid emulsion for a superhydrophobic surface research. TEOS and MTES derived sol-gel moieties can b...

Facile approach to prepare loose-packed cobalt hydroxide nano-flakes materials for electrochemical capacitors
Cobalt hydroxide nano-flakes are successfully synthesized by a facile chemical precipitation method. Electrochemical characterization is performed using cyclic voltammetry, chronopotentiometry and impedance spectroscopy, respectively. These cobalt hydroxide nano-flakes maintain high utilization at high rates of discharge. A maximum specific capacitance of 735 F g−1 can be achieved in 2M aque...

NPG Asia Materials 2012, 4, doi:10.1038/am.2012.26 "Biaxial stress controlled three-dimensional helical cracks"
Cracks are Janus-faced, which cause material failure on one hand and serve as a powerful approach for material processing on the other. To predict cracks and control them in a desired manner, foundational fracture mechanisms are continuously being pursued, based on simplified modes of planar cracks. In reality, cracks usually occur in a three-dimensional (3D) irregular manner. Prediction of 3D fra...

[Advanced Functional Materials] Manipulating the Motion of Gold Aggregates Using Stimulus Responsive Patterned Polymer Brushes as Motor
An important goal and major challenge of material science and nanotechnology
is building nanomotors for manipulating the motion of nanoparticles (NPs). Here, it is demonstrated that patterned, stimulus-responsive polymer brush microstructures can be used as motor arrays to manipulate the movement of gold NP aggregates in response to external stimuli that induce a conformational change in the bru...

Journal of Materials Chemistry 2011: Dendrimer modified magnetic iron oxide nanoparticle/DNA/PEI ternary magnetoplexes: a novel strategy for magnetofection
As a powerful technology to enhance the efficiency of gene delivery, magnetofection has attracted considerable attention in the past decade. In this work, we introduced 6 generation of PAMAM dendrimer modified superparamagnetic nanoparticles (DMSPION-G6) to PEI/DNA polyplexes by a two-step process and enhanced the transfection efficiency of PEI with the help of a magnetic field. We prepared DMSPIO...

Acid blue AS doped polypyrrole (PPy/AS) nanomaterials with different morphologies as electrode materials for supercapacitors
Accepted Man
The polypyrrole (PPy) nanomaterials with different morphologies were prepared via
the chemical oxidative polymerization of pyrrole in the presence of acid blue AS (AS)
as the dopant and surfactant. Increasing of the feeding ratio of AS, the morphology of
the resultant acid blue AS doped polypyrrole (PPy/AS) nanomaterials changed from
nanoparticles to clusters of nanofibers and...

Adv. Mater., 2011, 23, 2134-2148: An Emerging Pore-Making Strategy: Confined Swelling-Induced Pore Generation in Block Copolymer Materials
Block copolymers (BCPs) composed of two or more thermodynamically incompatible homopolymers self-assemble into periodic microdomains. Exposing self-assembled BCPs with solvents selective to one block causes a swelling of the domains composed of this block. Strong swelling in the confinement imposed by the matrix of the other glassy block leads to well-defined porous structures via morphology recon...

[Advanced Materials] Organic/inorganic Hybrid Hollow Spheres Prepared from TiO2-stabilised Pickering Emulsion Polymerization
Organic/inorganic hybrid hollow spheres are prepared from TiO2-stabilized Pickering emulsion polymerization. By self-organization of TiO2 nanoparticles at the interface of oil (monomer and solvent) and water, O/W colloidosomes are formed as polymerization vessels to obtain organic/inorganic hybrid hollow spheres. The diameter and mechanical stability of hybrid hollow spheres can be tailored ...

[Polymer] Confined photo-catalytic oxidation: a fast surface hydrophilic modification method for polymeric materials
When a very thin persulfate salt aqueous solution layer (mum) was sandwiched between two polymer films and strong UV light irradiated the assembly from the side transparent to UV light, a fast surface hydrophilic modification method for most of commercial polymeric materials was developed. For example, irradiating for 90 s and using 30 wt% ammonium persulfate, the static surface water conta...
