177. Graphene-Wrapped Polyaniline Hollow Spheres As Novel Hybrid Electrode Materials for Supercapacitor Applications.
Polyaniline hollow spheres (PANI-HS)@electrochemical reduced graphene oxide (ERGO) hybrids with core−shell structures have been fabricated via a solution-based coassembly process. The hollow nanostructured designing for the PANI-HS greatly enlarges the specific surface area, providing high electroactive regions and short diffusion lengths for both charge and ion transport. The wrapping of ER...

Preparation and performance of a novel thermoplastics polyurethane solid–solid phase change materials for energy storage
Phase change materials (PCMs) are a series of functional materials with storing and releasing energy properties. PCMs are able to adjust and control the environment around them through storing and releasing energy during phase change process. Based on the phase change theory, bis(1,3-dihydroxypropan-2-yl)4,4′-methylenebis(4,1-phenylene)dicarbamate, a novel tetrahydroxy compound, was designed and ...

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...
