Supercritical Carbon-Dioxide-Assisted Deposition of Pt Nanoparticles on Graphene Sheets and Their Application as an Electrocatalyst for Direct Methanol Fuel Cells
A combination of graphene with metal particles is particularly attractive due to the enhanced performance of the hybrid materials. However, direct loading of uniform metal
nanoparticles such as Pt on graphene remains a challenge due to the hydrophobic nature of graphene. We herein demonstrate that Pt nanoparticles with uniform size and high dispersion were deposited on graphene surfaces via a faci...

Surface Functionalized Barium Sulfate Nanoparticles: Controlled in situ Synthesis and Application in Bone Cement
The controlled synthesis of surface functionalized BaSO4 nanoparticles with the diameter below 50 nm is achieved by combining the in situ generation of SO42- and the use of difunctional surface modification agent of (2-(Methacryloyloxy) ethyl dimethyl-(3-sulfopropyl) ammonium hydroxide (MSAH). Particularly, a pre-decomposition process of the SO42- precursor (S2O82-) is applied to decouple the in s...

Application of corncob-based activated carbon as electrode material for electric double-layer capacitors
To investigate the influence of expansion pretreatment for materials on carbon structure, activated carbons(ACs) were prepared from corncob with/without expansion pretreatment by KOH activation, the structure properties of which were determined based on N2 adsorption isotherm at 77 K. The results show that the expansion pretreatment for corncobs is beneficial to the preparation ...

[Materials Chemistry and Physics] Controlled growth of metal nanoparticles on amino-functionalized polystyrene microspheres and their application in surface-enhanced Raman spectroscopy
This paper describes the preparation of hybrid materials of metallic nanoparticles (NPs) coated amino-terminated polystyrene (PS-NH2) microspheres by seed-mediated growth technique, and their application in surface-enhanced Raman spectroscopy (SERS). In our approaches, monodisperse PS microspheres are firstly prepared using dispersion polymerization with a subsequent nitration and amination to ach...

Polypropylene random copolymer in pipe application: Performance improvement with controlled molecular weight distribution
The performance of polypropylene random copolymer (PP-R) for pipe applications, including their processibality and final mechanical properties, can be balanced by finely controlling the molecular weight distribution (MWD). In this study, two representative samples chosen from a material optimization design procedure were analyzed. Rheology tests showed that broadening MWD will improve the processa...

Ag3PO4/ZnO: an efficient visible-light-sensitized composite with its application in photocatalytic degradation of Rhodamine B
The efficient visible-light-sensitized Ag3PO4/ZnO composites with various weight percents of Ag3PO4 were prepared by a facile ball milling method. The photocatalysts were characterized by XRD, DRS, SEM, EDS, XPS, and BET specific area. The OH radicals produced during the photocatalytic reaction was detected by the TA–PL technique. The photocatalytic property of Ag3PO4/ZnO was evaluated ...
