A reproducible mechano-responsive luminescent system based on a discotic crown ether derivative (1) doped with a small amount of fluorophore has been prepared. The emission intensity was enhanced when the material was subjected to mechanical shear with localized response.
This paper reports development and thermal characterization of tin-capped vertically aligned multiwalled carbon nanotube array composites for thermal energy management in load-bearing structural applications. Three-omega voltage measurements are used to characterize thermal conductivity in the vertically aligned multi…
Mesoporous silica (m-SiO2) coated gadolinium (Gd) ions-doped upconversion nanoparticles (UCNPs) are regarded as one of most attractive nano-platforms which hold great potential in future cancer theranostics. The current general synthetic strategy for such promising structures includes the extraction of surfactant mole…
In this study, we report on electrochemically deposited CoS onto ITO conducting glass substrates as counter electrodes for efficient quantum dot-sensitized solar cells (QDSCs). The CoS/ITO counter electrodes show remarkable electrocatalytic activity for the reduction of polysulfide compared to that of the CoS/ITO coun…
We report on the growth of a different orientation plane of Ni3TeO6 single crystal by the flux growth method for the first time. X-ray diffraction is used to characterize the single crystal and it crystallizes into the trigonal structure having space group R3 with lattice parameters of a = 5.1087 Å and c = 13.767 Å. T…
Glasses with the composition 51.9SiO2·21.2MgO·21.2Al2O3·5.7ZrO2 (in mol%) were crystallized in different annealing steps at 950 °C and 1060 °C. Using X-ray diffractometry and high resolution (scanning) transmission electron microscopy with energy-dispersive X-ray spectroscopy, it is found that the annealing-induced de…
A multiphase composite film composed of nickel(II) hydroxide and cobalt(II) hydroxide was synthesized by a novel co-precipitation method. The film exhibited high capacitance and stable cyclic retention because of its 3D network nanostructure and high conductivity due to CoOOH evolved during cycling.
Reconstruction of the human auricle remains a challenge to plastic surgeons, and current approaches are not ideal. Tissue engineering provides a promising alternative. This study aims to evaluate the chondrogenic potential of bone marrow-derived mesenchymal stem cells on a novel, auricular-shaped polymer. The proposed…
In situ high-energy X-ray diffraction coupled to atomic pair distribution function analysis is used to obtain fundamental insight into the effect of the reactive gas environment on the atomic-scale structure of metallic particles less than 10 nm in size. To substantiate our recent discovery we investigate a wide range…
A supramolecular crystal of 1,4-diazabicyclo[2.2.2]octane hydrochloride, [C6H13N2]+Cl−·3H2O, exhibits extremely strong negative thermal expansion (NTE) and one-dimensional relaxor ferroelectricity, as evidenced by single-crystal X-ray and neutron diffraction, and by dielectric spectroscopy measurements. The highest ev…
Due to its bright yellow-to-red emission, europium doped Ca2SiS4 is a very interesting material for phosphor converted light emitting diodes. The emission spectrum is highly dependent on the Eu concentration and can consist of more than one emission band. We combined X-ray absorption fine structure and photoluminescen…
A LiCaPO 4 :Eu 2+ phosphor with high photoluminescence was synthesized using a polymerizable complex (PC) method employing a water-soluble polyethylene glycol-conjugated phosphate ester (PEG-P). PEG-P could be obtained from a reaction among polyethylene glycol 300, phosphorus pentoxide, and pyrophosphoric acid. The PE…
We use the oxo-ester mediated native chemical ligation (NCL) reaction to generate a peptide self-assembly process to make supramolecular nanofibers and self-supporting gels.
The electrochemical characteristics of the electrical double layer capacitors consisting of the microporous titanium carbide derived carbon (TiC-CDC) electrode in 1M (C 2 H 5 ) 3 CH 3 NBF 4 solutions in 4-methyl-1,3-dioxolan-2-one, (so-called propylene carbonate (PC)), 4-fluoro-1,3-dioxalan-2-one, (so-called fluoroeth…
Polyurethane-Urea-Silica (PUUS) hybrid solutions were synthesized by a two-stage process, based on the use of polyoxypropylene glycol (PPG), 4,4′-dicyclohexyl methane diisocyanate (H12MDI), 1,4-butane diol, 3-aminopropyl-trimethoxysilane (APrTMOS) and a suitable amount of solvent. Following knife-coating and curing re…
In this work, a novel environmental-friendly waterborne polyurethane/ZnAl-layered double hydroxides/ZnO nanoparticles composite (WPU/ZnAl-LDHs/ZnO) was synthesized via in-situ polymerization. ZnAl-LDHs and ZnAl-LDHs/ZnO were synthesized by refluxing in an oil bath. In order to disperse ZnAl-LDHs/ZnO homogeneously into…
Stable blue emissive hyperbranched conjugated polymer nanoparticles with tunable particle sizes were synthesized by Suzuki polymerization in miniemulsion, which could be facile soluble in common organic solvents after complete removal of surfactants. As highly sensitive fluorescent probes for picric acid, they exhibit…
Nanotechnology is a new booming science, which has leaped huge significant achievements for only short dozens of years, and created so much wealth for human beings. Their usages on environmental security have been ignored by public, however, multiples of evidences have been demonstrated nano-materials would perform di…
The effect of precipitated phases on the pitting corrosion of a Z3CN20.09M cast duplex stainless steel (CDSS) which has been widely used in primary coolant pipes of nuclear power plants was investigated by using isothermal aging treatment and potentiodynamic anodic polarization methods. It was found that M 23 C 6 carb…
Recently, layered double hydroxides (LDHs) have been studied as anion conductors for fuel cell applications because of their anion exchange properties and better thermal stability (up to 150 °C) than those of anion exchange polymers. However, the conductivity of the LDHs is very low, under 10−3 S cm−1 at room temperat…
