Synthesis and thermal energy storage properties of the polyurethane solid-solid phase change materials with a novel tetrahydroxy compound
Based on the phase change theory, a novel tetrahydroxy compound (THCD) was designed and prepared. Depending on the spatial structure of the tetrahydroxy compound, a form-stable thermoplastic polyurethane solid–solid phase change material (TPUPCM) was synthesized via employing PEG as soft segments, while multi-benzene ring structure made by 4,4′-diphenylmethane diisocyanate and tetrahydroxy compo...

Mesoporous Co3O4 materials obtained from cobalt-citrate complex and their high capacitance behaviour
In this work, amorphous and mesoporous Co3O4 material is obtained from the calcination of loosely packed Co3O4/Co(OH)2 nanosheets which are synthesized by the formation and disassociation of cobalt ecitrate complex reaction. We propose that Co nanoparticles are completely oxidized to form the stable cobaltecitrate complex in the presence of sodium citrate and oxygen, and cobaltecitrate complex dis...

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...
