A novel copolymer based on bis(4-(1H-pyrrol-1-yl)phenyl)methane (BPM) and 3,4-ethylenedioxythiophene (EDOT) is successfully synthesized and characterized through electrochemical methods. The polymer film exhibits three distinct colors (khaki, yellow green, midnight blue) under different potentials, reasonable optical…
A new cyanostilbene based molecule, (2Z,2′Z)-3,3′-(4,4′′-dimethyl-[1,1’:4′,1′′-terp-henyl]-2′,5′-diyl)bis(2-(3-methoxyphenyl)acrylonitrile) (DMCS-PMP), has been designed and synthesized. Photoluminescence spectrum (PL) and scanning electron microscopy (SEM) analyses indicated that DMCS-PMP possessed extraordinary aggr…
In order to improve the dispersibility of CeO2 nanoparticles and reduce the environmental pressure, the dispersibility and stability of CeO2 nano-powder in water-ethanol suspensions was investigated in this paper. The results show that with the increasing of volume fraction of ethanol, the sedimentation rate of CeO2 n…
Commercial purity aluminum powder of irregular shape and ligamental morphology having average particle size of 75 µm was blended with medium carbon steel short fibers having average diameter of 100 µm and maximum length up to 1000 µm. The green compacts of pure aluminum and reinforced compositions were hot-pressed in…
This article describes to what extent the addition of energy by-products into the structures of the technical hemp filling materials influence their properties. The article focuses on the changes in physical-mechanical and thermal technical properties of materials after the addition of ash or FBC ash or slag in the bi…
TiO2 nanocrystals with the grain size of 12–20 nm were synthesized by the hydrothermal precipitation with Ti(SO4)2 and CO(NH2)2 as raw materials. The precursor was characterized by thermogravimetric/differential scanning calorimetry (TG/DSC), X-ray diffraction (XRD) and transmission electron microscope (TEM). The infl…
A new organic sol-gel spin-coating method was adopted to prepare the vanadium oxide (VOx) thin films. In this method, the sol-gel adopted was formed from the dispersion consisted of different proportions of V2O5 powder, benzyl alcohol and iso-butanol. Spin-coating technology and thermal-resistance properties of the VO…
Porous silicon/titania structures have been prepared for the first time by a sol-gel process in which a porous silicon layer was produced on single-crystal p -type silicon wafers and the titania was obtained from Ti-containing sol. The formation of TiO 2 , predominantly in the form of anatase, on the porous silicon su…
In order to further miniaturize the silicon-based micro direct methanol fuel cell (μDMFC), a novel method of fabricating MEMS-based single is μDMFC introduced. Using the silicon micromachining techniques, including thermal oxidation, optical lithography, wet etching, silicon anodization, physical vapor deposition, ele…
We investigated the heat capacities of SbSI and SbSBr using ab-initio calculations based on the density-functional theory. The full-potential linearized augmented plane wave method was used with the generalized gradient approximation. To benchmark our calculations, we compared the lattice heat capacity at constant vol…
A progressive approach to industrial use of synchrotron radiation (SR) in Japan was initiated in the mid-1980s at the Photon Factory of KEK with the installation of the first dedicated beamlines by several leading electronic companies. Their original goals were to promote R&D of X-ray lithography technology as a candi…
Hydrogen peroxide (H 2 O 2 ) is a potent oxidant that influences the growth and well-being of living organisms, and development of a probe to monitor H 2 O 2 in biological media is of broad interest to chemistry, biology, and medicine. Herein, CdS:Mn–polysulfido nanoclusters (NCs) are demonstrated to be chromogenic pr…
A simple and versatile approach was developed to support small-sized ZnO nanoparticles with 5 nm on graphene (GR) sheets by the co-precipitation method, and the photocatalytic property was evaluated. The experimental results showed that the resultant GR/ZnO composite was proven to possess a better photocatalytic activ…
A design configuration is presented for integrated series connection of micro direct methanol fuel cells in a planar array. The series path is oriented in a “flip-flop” configuration with electrical interconnections made by thin-film metal layers that coat the flow channels etched on the silicon substrate, presenting…
Readily synthesized monosubstituted aliphatic acyclic carboxamides have a physiological cooling effect similar to that obtained with menthol. Among the monosubstituted aliphatic acyclic carboxamide...
We have studied composition dependences of kinematic viscosity for Fe-Cu melts with the aim of determining the temperature and composition ranges where chemically inhomogeneous Fe-Cu melts exist. Measurements were performed during heating and cooling in the temperature range from 1550 to 1700°C. Evidence has been foun…
The ability to form patterned surface nanostructures has revolutionized the miniaturization of electronics and led to the discovery of emergent behaviors unseen in macroscopic systems. However, the creation of such nanostructures typically requires multiple processing steps, a high level of technical expertise, and hi…
This article reports on the synthesis, photoluminescence and thermoluminescence properties of samarium and dysprosium ions doped barium gadolinium titanate powder ceramics.
