We present low-temperature specific heat of the electron-doped Ba(Fe 0.9 Co 0.1 ) 2 As 2 , which does not show any indication of an upturn down to 400 mK, the lowest measuring temperature. The lack of a Schottky-like feature at low temperatures or in magnetic fields up to 9 T enables us to identify enhanced low-temper…
The clinical application of apomorphine, a dopamine receptor agonist for treating Parkinsons disease, is limited by its instability and the need for frequent injections. In the present work, apomorphine was encapsulated within liposomes to protect it from degradation and enhance the permeability across the blood-brain…
Two amphoteric cruciforms 6 and 7 (XF; 4,4'-[(1E,1'E)-(2,5-bis{[4-(dibutylamino)phenyl]ethynyl}-1,4-phenylene)bis(ethene-2,1-diyl)]diphenol, 4,4'-[{2,5-bis[(E)-4-(dibutylamino)styryl]-1,4-phenylene}bis(ethyne-2,1-diyl)]diphenol) were prepared by a Horner reaction followed by a Sonogashira coupling and subsequent depro…
The CaCu 3-x Zn x Ti 4 O 12 (CCZTO) (x=0, 0.06, 0.1, 0.2) ceramics were prepared by Sol–gel method. The XRD pattern shows that crystal structure of the sample with no Zn is basically single-phase. The SEM results indicate that the samples have porous structures and the gain size decreases with the content of Zn increa…
The interfacial electronic structures of zinc oxide (ZnO)/copper-phthalocyanine (CuPc) were investigated by in situ x-ray and ultraviolet photoelectron spectroscopy (UPS) to determine the effects of air contamination on the ZnO substrate. UPS spectra showed that the 0.2 eV of the interface dipole is generated at the i…
This special volume brings together the latest advances in, and applications of, iron and steel, micro/nano materials, metal alloy materials, composites, earthquake-resistant structures, materials and design, tooling testing and evaluation of materials, waste engineering and management, etc. It will not only provide r…
We observed stable photoluminescence from close-packed cubic SiC nanocrystals that are self-assembled into thin solid film. The peak wavelength shifts from blue to near UV with increasing excitation energy and follows well the quantum-confinement effect. The photoluminescence excitation spectrum indicates a 3.47 eV ba…
Amphiphile PQP14-Komplexe bilden durch den Einsatz von Alkylsulfonaten oder Disulfonaten als Anionen auf kontrollierte Art und Weise zweidimensionale (2D) Nanostrukturen (siehe Bild). Die Morphologien dieser 2D-Nanostrukturen beeinflussen die Ionenleitfähigkeit einer Mischung der PQP14-Komplexe mit Lithiumsalzen nachh…
In this letter, we report a kind of smart surfaces with reversible switching between isotropy and anisotropic wetting, which was realized by one-direction curvature tuning on flexible superhydrophobic surfaces. Along the curvature change, the wettability of this flexible film was changed from isotropic state (150°/150…
The motivation of this work is to lessen the dependence on non-degradable plastic packaging which can lead to waste disposal problems. In this paper, the alternative biodegradable material developed by using local available sago starch in the present of biodegradable glycerol as plasticizer, as well as a set of compos…
Antireflective phosphor coatings having disordered surface nanostructures were fabricated by a sol-gel dip coating method and a subsequent hot water treatment. Thin films of a Bi(3+),Eu(3+)-codoped YVO4 red phosphor were first prepared and effects of the addition of an aluminum source to precursor solutions on their m…
This investigation is done to select the best composite on bending strength and stiffness derived from different parts of sugar palm fibre reinforced unsaturated polyester composites. Sugar palm tree is one of the most popular natural fibres. The fibre was obtained from the sugar palm tree and mixed with unsaturated p…
Using the discrete dipole approximation method, two visible extinction peaks are found for Ag nanohelixes. Both of them redshift periodically in an approximate half pitch with the helix height and redshift linearly with the helix diameter and pitch height. At the two absorbance peaks, an integer number of E-field maxi…
We report a method to predict the frequency dependence of coercive fields in ferroelectric films. The deduction of this method as well as the analysis are based on investigations of intrinsic switching kinetics of high-quality, single-crystal-like, epitaxial Pb(Zr 0.2 Ti 0.8 )O 3 thin films with extended defect-free s…
Increasing worldwide environmental awareness is an encouraging scientific research into the development of cheaper, more environmentally friendly and sustainable construction and packaging materials. Kenaf fibre is a natural fibre which is growing in popularity due environmental issues and its properties as filler. Ep…
We have found that there is a narrow but distinct window in oxygen pressure for growing phase-pure epitaxial EuO films by a pulsed laser deposition. With finely decreasing the oxygen pressure, the electrical property is varied from insulating to metallic with an enhancement in Curie temperature from 70 to 120 K. The a…
Cellulose and lignocellulose have great potential as nanomaterials because they are abundant, renewable, have a nanofibrillar structure, can be made multi¬functional and self-assemble into well-defined architectures. New methods for liberating these materials, including nanodimensional cellulose fibrils, macromolecule…
Nanostructured porous silicon (nanoPS) basically consists in a network of silicon nanocrystals with high specific surface. Its intrinsic high surface reactivity makes nanoPS a very suitable material for the development of biosensors. In this work, the surface of nanoPS was functionalized by the use of (3-aminopropyl)t…
Clusters of EuS nanocrystals formed through the thermal assembly of 2.5 nm nanocrystal monomers by varying the annealing temperature from 300 to 340 °C. Below 310 °C, oleate ligands stabilized on the surface of the EuS nanocrystals, giving rise to their low solubility in triethanolamine while facilitating monomer–mono…
The effect of electron beam (EB) irradiation on the optical properties of cadmium chloride (CdCl 2 )-doped polyethylene oxide (PEO) is studied. The films are characterized using Fourier transform infrared spectroscopy (FTIR) in KBr medium. The morphology study of the films is conducted using a scanning electron micros…
