Many offshore wind-power generators over MW-class are currently in operation in Europe and are now starting to be used in Japan. In order to develop large-scale offshore wind-power plants, we need to reduce the size and weight of power converters, including isolating transformers. A dc-dc converter with a high-frequen…
Efficient energy usage and energy conservation is the today's requirement for all researchers of IC engine. The usual method of producing heat from fuel is by the process of combustion, which is a chemical reaction between the fuel and oxidant. Thermodynamics is the science that deals with interaction between energy a…
A binder-free novel three-dimensional assembly comprising graphene, carbon nanoparticles and nickel hydroxide is presented as a supercapacitor electrode.
Luminescent silane-functionalized copper clusters are developed as a highly efficient catalyst to build up a recyclable and photoreversible color switching system based on the redox reactions of methylene blue.
Biocompatible and three-dimensional hybrid of salicylic acid (SA)-doped polypyrrole (PPy) and alginate (Alg) was synthesized and employed as a dual-stimuli responsive drug delivery platform. The PPy-Alg hybrid combined the electro-responsive feature of PPy and pH-sensitive feature of Alg. Releasing behaviors of the hy…
Waterborne UV-curable comb-shaped (meth)acrylate graft copolymers containing long fluorinated and/or siloxane side chains.
In this study, we have developed a simple photoassisted ligand assembly to fine-tune the photoluminescence (PL) of (11-mercaptoundecyl)-N,N,N-trimethylammonium bromide-capped gold nanodots (11-MUTAB-Au NDs). The 11-MUTAB-Au NDs (size: ca. 1.8 nm), obtained from the reaction of gold nanoparticles (ca. 3 nm) and 11-MUTA…
Di-block copolymers of <sc>l</sc> -lactide and (meth)acrylate were synthesized from PLLA macroinitiators, and the microphase separation of copolymers was observed.
The importance of raw graphite size to the capacitive properties of graphene oxide was discussed.
The mechanical behavior of SWCNTs is characterized using an atomistic-based continuum method. At nanoscale, interatomic energy among carbon atoms and the corresponding force constants are defined. Subsequently, we used an atomistic finite element analysis to calculate the energy stored in the SWCNT model, which forms…
A chitosan-silver nanocomposite (CAgNC) was synthesized in a green manner using low molecular weight chitosan (LMW-chitosan) and silver nitrate without applying external chemical reducing agents.
Chemical grafting of small molecule reagents onto polymeric fibrous materials, like paper, has been used to modify their wetting properties. Several reagents like trichlorosilanes, which can react with water or hydroxyls, have been used with the expectation that a monolayer, single molecule or polymerized single-molec…
The ability of SrFBr nanocrystals codoped with ∼1 mol% of Er <sup>3+</sup> and Yb <sup>3+</sup> to perform infrared-to-visible light upconversion is demonstrated. Excitation of Yb <sup>3+</sup> at 980 nm results in two-photon upconversion and green-yellow luminescence from Er <sup>3+</sup> , highlighting the potential…
The 2LiBH4-MgH2 + 20 wt% BaTiO3 composite was prepared by ball-milling LiBH4, MgH2 and BaTiO3, and the effect of BaTiO3 on the hydrogen storage properties of the composite was investigated. TG-DSC results show that the onset dehydrogenation temperature of the composite is 299 °C, which is 124 °C lower than that of 2Li…
BEA-type core–shell catalysts consisting of a core supporting Cu and Fe and a Ni-based shell were investigated for their ethanol steam reforming (ESR) activity.
Here we present a neutron tomography and in-situ radiography study on a sodium metal halide cell with mixed Fe/Ni chemistry during charge and discharge at 280°C. The neutron tomography data visualizes the cathode containing porous wick, Ni current collector and partly filled macro pores. Upon charging, the appearance…
Design, synthesis and single-crystal conformations of hybrid triple-stranded β-sheets composed of E-vinylogous residues are reported. Restricting conformational flexibility of β-strands through the insertion of carbon-carbon double bonds at facing positions leads to increased peptide crystallinity, which allowed unamb…
OBJECTIVE: Three-dimensional (3D) biomimetic nanofiber scaffolds have widespread ap- plications in biomedical tissue engineering. They provide a suitable environment for cel- lular adhesion, survival, proliferation and differentiation, guide new tissue formation and development, and are one of the outstanding goals of…
Analyze the composition of micro area of the laser etched surface via X-Ray Energy Dispersive Spectrometer, and by analyzing the elemental change rule of Al2O3-SiC composite ceramics, study the removal mechanism of laser direct etching on Al2O3-SiC composite ceramics, and compare with composite etching of water jet an…
Here we reveal that graphene oxide flakes, known for their nano- and two-dimensionality, can be used as a sacrificial support to replicate their nano- and two-dimensionality in photocatalytic titania using the Ti <sub>16</sub> O <sub>16</sub> (OEt) <sub>32</sub> polyoxotitanium cluster as a precursor.
