As the textile industry increasingly engages with technical applications, interest in electronic textiles is growing. This paper reviews the research and development (R&D), and commercialization efforts in conducting polymers and electronic textile materials by using conducting polymers. A brief historical overvie…
Using a first-principles approach based on density functional theory, this paper studies the electronic and dynamical properties of β-V 2 O 5 . A smaller band gap and much wider split-off bands have been observed in comparison with α-V 2 O 5 . The Raman- and infrared-active modes at the Γ point of the Brillouin zone a…
The effect of gamma irradiation on the dielectric properties and ac conductivity of a TlInS2 single crystal with a layered structure has been investigated in the frequency range from 5 × 104 to 3.5 × 107Hz. It has been shown that gamma irradiation of the TlInS2 single crystal with a dose of 104–2.25 × 106 rad leads to…
We investigate the organization of nanosized particles in a polymer brush by DPD simulations. The brush is composed of flexible chains grafted by one end to a solid substrate. The polymer-insoluble nanoparticles are treated as rather rigid aggregates of almost spherical form. Varying either the strength of interaction…
The material grown in a scanning electron microscope by electron beam-induced deposition (EBID) using Pt(PF3)4 precursor is shown to be electron beam sensitive. The effects of deposition time and postgrowth electron irradiation on the microstructure and resistivity of the deposits were assessed by transmission electro…
The use of carbon nanotubes (CNTs) as a conductive and high strength filler into polymer hosts has attracted great attention recently. However, in order to increase the conductivity of the polymer and to reinforce mechanically the polymer structure at low weight fraction of CNTs, the integration of the CNTs into the p…
Optical absorption spectra of natural Co-bearing spinel and staurolite were studied at different temperatures and pressures. In both minerals, two broad, intense structured bands in the range 5500-8000 and 15 000-19 000 cm-1, caused by electronic spin-allowed transitions 4 A 2 → 4 T 1 (4F) and 4 A 2 → 4 T 1 ( 4 P) of…
This paper presents an application of a hysteresis model that is coupled to an equivalent network for the calculation of the inrush current due to an arbitrary excitation of a transformer after a fault. The approach proposed, although using several simplifying assumptions, seems promising in order to calculate the opt…
We present a chemical vapor deposition (CVD) method for the growth of uniform single-walled carbon nanotube (SWNT) arrays on a stable temperature (ST)-cut single crystal quartz substrate using a mixture of methanol and ethanol as carbon source. It is found that introducing methanol during the growth can improve the de…
isolates) the results showed that the MBCs were in a range from more than 10 µg/ml to 0.62 µg/ml 30-90 minutes post-inoculation. Also, the range of MBCs for was 0.31 µg/ml to less than 0.15 µg/ml, while the range of MBCs for was from 2.5 to 0.62 µg/ml 30 to 90 minutes post-inoculation, respectively. Generally, the bac…
This study provides experimentally determined values for the actual micro-Raman spectroscopy sampling depth in zirconia ceramics (ZrO2) via line scans on a wedge-shaped sample. Common instrumental settings with metallurgical objective lenses in dry air, argon-ion, and helium-neon laser radiation of approximately 10 mW…

The drug development for neurodegenerative disorders are the major challenge to the science in 21st century. Many FDA approved drugs currently available in the market have limitations in crossing the blood brain barrier (BBB) owing to its complicated vasculature posed by the presence of specialized cells. Nanotechnolo…
Abstract A new Zn and Eu tungstate was characterized by spectroscopic techniques. This tungstate, of the formula ZnEu 4 W 3 O 16 , crystallized in the orthorhombic system and was synthesized by a solid‐state reaction. It melts incongruently at 1330°. The luminescent properties, including excitation and emission proces…
The authors report demonstration of a low-cost (∼1000 USD) interference lithography system based on a Lloyd’s mirror interferometer that is capable of ∼300nm pitch patterning. The components include only a 405nm GaN diode-laser module, a machinist’s block, a chrome-coated silicon mirror, substrate, and double-sided ca…
The formation of radiation-damage regions (radiation-damage cascades) in vanadium crystallites with internal structures (intergrain boundary) has been simulated by the molecular-dynamic method. The interatomic interaction is described within the embedded-atom method. A relatively small number of clusters of intrinsic…
The effect of pressure on the superconductivity of "111"-type Na 1− x FeAs is investigated through temperature-dependent electrical-resistance measurements in a diamond anvil cell. The superconducting transition temperature ( T c ) increases from 26 K to a maximum of 31 K as the pressure increases from ambient pressur…
Hyperpolarizability of conjugated molecules with relatively long π-system (three and more double bonds in the π-bridge) and molecular aggregates (composed of the same molecules) can be predicted at the Density Functional Theory level with the 6-31G basis set to within 5–10% (compared to 6-31+G* results), while 6-31G*…
In the present investigation, we evaluated the half-metallic-ferromagnetic/antiferromagnetic nature of Fe/Co/Ni doped ZnSe material systems. Our calculations show that for the majority spin channel, Zn0.75Fe0.25Se, Zn0.75Co0.25Se, and Zn0.75Ni0.25Se, are semiconductors, and for the minority spin channel, they are cond…
Abstract The synthesis of the C 2 ‐symmetrical ligand 1 consisting of two naphthalene units connected to two pyridine‐2,6‐dicarboxamide moieties linked by a xylene spacer and the formation of Ln III ‐based (Ln=Sm, Eu, Tb, and Lu) dimetallic helicates [Ln 2 ⋅ 1 3 ] in MeCN by means of a metal‐directed synthesis is desc…
