NCNST 10th Anniversary: (Adv. Mater. 28/2013)
In the true spirit of its collaborative founding by three Chinese universities, the National Center for Nanosciences and Technology of China this year celebrates its 10th anniversary with two special issues guest-edited by Professor Yuliang Zhao: one in Advanced Materials (Issue 28/2013) and one in Small (Issue 14/201…

Supercapacitors Based on Composite Polyaniline / Reduced Graphene Oxide With Network Nanocomposite Polymer Electrolyte
The paper describes investigation on new types of supercapacitors based on composite polyani-line/reduced graphene oxide with network nanocomposite polymer electrolyte. Its prototypes are all solid state. The new network polymer electrolytes based on polyethylene glycol diacrylate and nanoparticle SiO2 was synthesized…

Hybrid Sol-gel Coatings to Prevent Corrosion on Hot-dip Galvanized Steel in contact with cementious media
Corrosion of reinforcement is one of the prevailing causes of premature deterioration of reinforced concrete. Among the possible anti-corrosion measures, hot-dip galvanized steel extends protection increasing the service life of the rebars in aggressive environments. The zinc layer acts, as a physical barrier that hin…

Nanocrystalline Hydroxyapatite-Bisphosphonate Composites
The direct synthesis of hydroxyapatite─1,8-octan-bisphosphonic acid (HAp─BISPH) nanocrystals has been carried out in presence of increasing amounts of BISPH in solution, by hydrothermal method at 120 °C for 15 h. XRD, IR, NMR-MAS (31P, 1H and 13C), TEM, AFM, TGA and chemical analysis were used to characterize the stru…
Room-Temperature Electronically-Controlled Ferromagnetism at the LaAlO3/SrTiO3 Interface
Reports of emergent conductivity, superconductivity, and magnetism at oxide interfaces have helped to fuel intense interest in their rich physics and technological potential. Here we employ magnetic force microscopy to search for room-temperature magnetism in the well-studied LaAlO3/SrTiO3 system. Using electrical top…
Asymptotic theory of microstructured surfaces: An asymptotic theory for waves guided by diffraction gratings or along microstructured surfaces
An effective surface equation, that encapsulates the detail of a microstructure, is developed to model microstructured surfaces. The equations deduced accurately reproduce a key feature of surface wave phenomena, created by periodic geometry, that are commonly called Rayleigh-Bloch waves, but which also go under other…
Thermal Behavior of Nanoclay Reinforced Ultraviolet Curable Epoxy Acrylate
This study related to preparation of UV curable epoxy nanoclay nanocomposite and investigation on mechanical and thermal properties of their thin films. For achieving this UV-curable epoxy dimethacrylate was synthesized by epoxy resin (EPIKOTE 828), methacrylic acid, triphenylphosphine (PPh3) as catalyst and para-meth…
On the Benign One-Pot Preparation of Nanoporous Copper Thin Films with Bimodal Chan- nel Size Distributions by Chemical Dealloying in an Alkaline Solution
Nanoporous copper (NPC) thin films with bimodal channel size distributions can be benignly fabricated by one-pot chemical dealloying of dual-phase Al 27 at Cu alloy with hypereutectic structure in the NaOH solution. The microstructure of these NPC thin films was characterized using X-ray diffraction, scanning electr…
Surfactant Assisted Synthesis of LiFePO4 Nanostructures via Hydrothermal Processing
LiFePO4 is a potential cathode candidate for of secondary lithium batteries due to its low-cost, out-standing thermal stability and innocuity. In this paper, pure LiFePO4 obtained by hydrothermal method using cetyltrimethyl ammonium bromide (CTAB) as surfactant. LiFePO4 particles produced without any surfactant showed…
Preparation of Nanostructured Li2MnO3 Cathode Materials by Single-Step Hydrothermal Method
Nanosized (10~50 nm) cathode material Li2MnO3 was prepared for with MnSO4·H2O，KMnO4 and Li-OH aqueous solution as the precursor via single-step hydrothermal reaction by controlling the reaction time, proportion of processor, and the reagent concentration. The prepared materials were well crystallized and exhibited a m…
