Chemically synthesized poly(aniline-co-fluoroaniline) [poly(An-FAn)] powder were deposited on platinum substrates using thermal evaporation technique [poly(An-FAn)/vac]. These films were characterized using spectroscopic and cyclic voltammetry techniques. Electrical conductivity and molecular weight of copolymer have…
Indocyanine Green encapsulating liposomes (Lip/ICG) and scVEGF-Lip/ICG liposomes, decorated with site-specifically lipidated engineered single-chain vascular endothelial growth factor (scVEGF) for targeting VEGF receptors were tested as potential tracers for fluorescent tomography. Two groups of experiments were condu…
The reverse leakage current mechanisms of Schottky diodes prepared using liquid gallium on as-grown and cleaved tungsten diselenide surfaces were investigated by current-voltage method for the first time. The major leakage mechanism has been identified as tunneling current along with a small contribution of thermionic…
The reaction of Co(II) or Zn(II) acetate salt, 5-(4-carboxy-2-nitrophenoxy) isophthalic acid (H3cnpi) in the presence of N-containing molecules produces three new coordination polymers: [Zn(Hcnpi)(phen)2]·(H2O) (1), [Co(Hcnpi)(phen) (H2O)]n (2), and [Co0.5(H2cnpi)(H2O)2]·(H2O)·(dpe) (3) (H3cnpi = 5-(4-carboxy- 2-nitro…
The cytotoxic effects of Teucrium polium (Lamaceae) have been shown in some studies. However, the antitumor activity of the fractions of this herb has not been studied, neither has the pattern of cell death been evaluated yet. The inhibitory effect of Teucrium polium (T. polium) on U87 cells was evaluated by treatment…
The process of electrospinning has received remarkable amount of attention as this technique can be used to fabricate suitable scaffolds for cells. In order to control morphology of scaffold, parametric studies are necessary in customized melt electrospinning. In this study, we demonstrate that fiber di- ameter could…
Abstract Unusually small carbon nanoparticles were synthesized in a microwave plasma flow-reactor by pyrolysis of 0.3–1.2% CH4, C2H4, and C2H2 with 0.3–3.6% addition of molecular hydrogen in argon. Final particle sizes were analyzed by in-line particle-mass spectrometry (PMS) and by transmission electron microscopy (T…
Nano-enhanced solar cells incorporating III-V quantum wells or quantum dots have the potential to revolutionize the performance of photovoltaic devices. Extended spectral response characteristics have been widely demonstrated in both quantum well and quantum dot solar cells using a variety of different III-V materials…
The clinical use of radiation image detectors is influenced by the degree to which patients are exposed to radiation. Phosphors are being used as the radiation receptor materials in a number of radiation imaging systems for the detection of radiation. Rare earth phosphors such as those of Gd, Y, Lu, and La are attract…
A model for projectile fragmentation is developed whose origin can be traced back to the Bevalac era. The model positions itself between the phenomenological EPAX parametrization and transport models like "Heavy Ion Phase Space Exploration" (HIPSE) model and antisymmetrised molecular dynamics (AMD) model. A very simpl…
We Consider a Layered Elastic Body, Consisting of Base Material with Young's Modulus E0 and Poisson's Ratio ν0 and Coating Thickness δ, Respectively, with E1 и ν1. the Thickness of the Base Is much Greater than the Thickness of the Coating. A Stiffness Model of the Layered Body with Loading His Axisymmetric Load, whic…
Carbon nanotube (CNT)/metal-cluster-based composites are envisioned as new materials that possess unique electronic properties which may be utilized in a variety of future applications. Superparamagnetic behavior was reported for CNTs with Gd ions introduced into the CNT openings by internal loading with an aqueous Gd…
The intrinsic layer in an amorphous-silicon solar cell is usually several orders of magnitude thicker than the p- and n-layers to increase the electron-hole pair generation in the intrinsic layer and to decrease the recombination losses in the p- and n-layers. We hypothesized that a nohomogeneous intrinsic layer may t…
A vertical structure with a back contact layer is suggested for silicon quantum dots (Si QDs) solar cells to overcome the current crowding effect arising from the high lateral resistance in the emitter layer of the existing mesa-structured Si QDs solar cells on quartz substrates. Molybdenum (Mo) is widely used as the…
Lead-free compound $(Na_{0.5}Bi_{0.5})(Zr_{0.75}Ti_{0.25})O_3$ was prepared using conventional ceramic technique at $1070^{\circ}C$ /4h in air atmosphere. X-ray diffraction analysis showed the formation of single-phase orthorhombic structure. Permittivity data showed low temperature coefficient of capacitance ( $T_{CC…
Penelitian ini bertujuan untuk menganalisis pengaruh penambahan serbuk tembaga (Cu) terhadap nilai konduktivitas dan energi gap PANi-Cu. Pengukuran konduktivitas ini dilakukan dengan variasi suhu yaitu 298 K dan 373 K. Kenaikan suhu pada saat pengukuran menyebabkan peningkatan konduktivitas bahan tersebut. Konduktivit…
Electrophysical and optical properties of heterogeneous composite systems based on nanosilicon (nc–Si) and silica aerogel (SiOx) powders have been investigated using impedance spectroscopy and FTIR spectroscopy methods. In FTIR transmittance spectra the presence of vibration modes of hydroxyl groups covering the inter…
In this research, the effect of centipede yarn production parameters – band yarn count and chain number – on drape and crease recovery behaviors of woven fabrics produced with these yarns were investigated. Polyester centipede yarns were produced on a Crochet machine with three different count (150, 300 and 600 denier…
During the fission process, the atomic nucleus deforms and elongates up to the two fragments inception and their final separation at the scission deformation. The evolution of the nucleus energy with deformation defines a potential energy landscape in the multidimensional deformation space. It is determined by the mac…
The aim of the research published in the paper was to study the role of the false-twister in the formation of wrap yarns on a hollow spindle machine. Three cases were investigated as follows: without use of false-twister, with single wrapping around the false-twister, and with double wrapping around the false-twister.…
