Abstract—Metal fiber content is often a measured parameter for electromagnetic shielding fabric (ESF). A commonly used method is combustion measuring, but measuring speed was slow and measured fabric damaged. This study proposes a new method based on computer image analysis for recognition of metal fiber content per u…
This study examined co-deposition of Al and Zn on active AZ91D magnesium alloy using ionic liquid electrodeposition. A room temperature Lewis acidic ionic liquid made of aluminum chloride (AlCl 3 ) and 1-ethyl-3-methylimidazolium chloride (EMIC) with a mole ratio of 60:40 was used as the bath for pure Al electrodeposi…
Micro- and nanosized, long fibers of heterobimetallic complexes, consisting of macrocyclic oxamide complexes (CuL) and transition-metal ions (Mn), have been successfully synthesized by a simple solvothermal approach. The as-prepared products were characterized by scanning electron microscopy, powder X-ray diffraction,…
Layer-by-layer (LbL) assembly provides a facile approach for fabricating organized nanoscale structures with outstanding mechanical, electrical, optical, electrochemical, and photoelectric properties. Revelation of electrical and photoelectric performance of LbL membranes made from graphene oxide would be profound for…
Circuit and multipolar approaches are presented to investigate the correlation between absorption and scattering processes in 2D problems. This investigation was inspired by earlier works of R. E. Collin, which pointed out deficiencies of the Thvenin/Norton circuit models to evaluate the scattered and absorbed powers…
Four new dendritic structures carrying perfluorobenzyl bromide on the surface and calix[4]arene and cyclam as a core were synthesized by using the convergent approach. These structures were determined by 1H-NMR, 13C-NMR and elemental analysis. Thermal stabilities of fluorinated dendritic structures were investigated u…
Here we report the use of buckycolumn (BC) carbon nanotube materials as electrochemical sensors for measurement of key biological molecules. The BC electrode was able to conduct stable long-term measurements of dopamine compared to the more commonly used electrode materials for bioanalysis.
We described a facile method for assembly gold nanochains by using octreotide acetate as template in aqueous environment. In acidic solution, octreotide acetate was conferred positive charges and its structure changed to chain‐like. The monodisperse negative gold nanoparticles were bound to the surface of octreotide a…
Electrochemical impedance spectroscopy is used to monitor the real-time network response of 1 cm 2 areas of ferroelectric PbZr 0.52 Ti 0.48 O 3 (PZT) thin films solution deposited onto platinized silicon wafers and exposed to 0.1 N H 2 SO 4 over 48 hours. Development of equivalent circuits to model the competing proce…
Hydrogen visibly bubbles during photocatalytic water splitting under illumination with above-bandgap radiation, which provides a direct measurement of local gas-evolving reaction rate. In this paper, optical microscopy of superfield depth was used for recording the hydrogen bubble growth on Cd0.5Zn0.5S photocatalyst i…
The phenomenon of nanoparticle-induced fluorescence lifetime enhancement of protonated 8-propoxyquinaldine thiol derivatives, covalently attached to the surface of gold (Au) nanoparticles, is reported. The observed lifetime enhancement occurs due to the parallel orientation of the protonated PQT with respect to the Au…
In this work, we report the transparent pure and Sn-doped zinc oxide (ZnO). The films were deposited onto microscope glass substrate which was heated at 350±5C° by ultrasonic spray pyrolysis (U S P) deposition technique. The concentrations of Sn were selected within the range of 0-3% by step of 0.5% and the time depos…
Paragraph is about mathematical interpretation of transformer insulation system. Base of this system is composed by two elements oil and paper. We need to simulate this system for more precisely results from measurement. Section three describes how to calculate relaxation currents and how that currents are generated.…
Photochemical crosslinking is a best alternative method when compared to conventional crosslinking methods such as chemical and physical methods, by using vitamins like riboflavin and ascorbic acid as photochemical initiators to enhance the physicochemical properties of collagen poly (vinyl pyrrolidone) blend without…
It is found that surface energy plays the dominant role in direct e-beam etching of single crystal ZnO and ITO nanostructures through a surface etching (sputtering) process, especially for electron energies smaller than the characteristic energy for bulk atoms knock-off. This mechanism can be used for the fabrication…
Environmental impact plays an ever-increasing role in the industrial production of materials, and because of its importance, the scientific community is examining a wide variety of new materials that are more environmentally friendly. Bioplastics are characterized by the fact that the usual petrochemical resins (polyp…
The synthesis of ordered mesoporous carbons (OMCs) was carried out under acidic aqueous conditions, by cooperative self-assembly of phenol–formaldehyde resol and surfactant F127. The influence of the acid source on the structural and anti-oxidation properties of the OMCs was investigated. The acids (HCl, HNO3, H3PO4 a…
We report here the use of gold nanoparticle (AuNP) and gold nanostar (AuNS) assemblies modified with oligonucleotides for the detection of target DNA molecules through SERRS. SERS activities of assmblies consisted of 16 nm AuNPs, 30 nm AuNSs and 100 nm AuNSs were compared. Interaction of localized surface plasmon reso…
For the incipient post-Si era of digital devices, III-V compounds are mature candidates among n-type active channels as technology booster to increase electron mobility, but – unlike Si – they lack a well-established technology for dielectric gating which may bear aggressive device scaling. Here we propose a viable ro…
An azimuthal anchoring direction of many different types of nematic liquid crystals has been investigated on a rubbed poly(vinyl cinnamate), PVCi, film. It was found that liquid crystals with and without polar groups aligned perpendicular and parallel to a rubbing direction on a rubbed PVCi surface, respectively. The…
