Kiss-roll coating is proposed as a potential method to manufacture hybrid bicomponent fibers for the high-volume production of thermoplastic composites. A high-speed study is provided to prove the feasibility of the approach and the influence of different process parameters is investigated via a second-degree full fac…
In this paper, Ag nanoparticles with various sizes and forms are made by using reduction methods of Ag ions in aqueous solutions in the presence of strong reducing agents like hydrogen peroxide (NaBH4) with different concentrations of silver nitrate AgNO3 (1mM to 0.9mM) improving its effect on the stability of the nan…
This study focuses on the control of the light matter phenomenon in the visible wavelength range. In order to absorb the incoming light, silver nanospheres and nanoprisms are chemically synthesized and embedded in a non-absorbing and transparent polymer host matrix. By combining nanospheres and nanoprisms in the same…
Successive deposition of uniform metal droplet is a new kind of 3D printing and rapid prototyping (RP) technology. Broad interests have been aroused in the deposition of metal droplets due to its potential application in microstructures fabrication. In this paper, the 3D models based on a volume of fluid (VOF) method…
2-Amino-5-fluorobenzonitrile (2A5FBN), a novel molecule has been reported after mutually experimental and theoretical approaches on molecular atomic structure, vibrational spectra, Non-linear Optics (NLO) properties, Natural Bond Orbital (NBO) analysis and Molecular Electrostatic Potential (MEP). The Fourier Transform…
Despite a high technical relevance and 35 years of observation, self-organized morphogenesis of nanoporous sponge-like amorphous structures during exposure of selected covalent materials to energetic ions is still insufficiently understood. Due to the presence and absence of these effects in amorphous Ge and Si, respe…
We investigated the synthesis conditions and magnetic properties of non-magnetic-ion-substituted Ca-based hexagonal ferrites, Ca0.8La0.2Fe8.0−2xMgxTixO19−σ (x = 0.1–3.5) and Ca0.8La0.2Fey−xAlxO19−σ (x = 1.0–5.0, y = 8.0–10). We found that Mg-Ti-substituted Ca-based M-type ferrites formed at x = 0.1 and 0.2 at above 12…
Materials are classified under the three categories of (i) metals (ii) non-metals and composites. Of these, metals and its alloys broadly meet all requirements to be considered as the most suitable engineering material. Amongst metals, the largest use in the petrochemical industry is of ferrous metals and alloys like…
The intermetallic compound ZrCu experiences a transformation from a parent phase into a martensitic phase with rapid cooling. ZrCu possesses considerable promise as a high-temperature shape memory alloy. In the present study, the shape memory effects of ZrCu, which was formed in a Zr-Cu-Al ternary alloy, was investiga…
Introduction of asymmetry into charge-transfer complexes composed of iron phthalocyanines was achieved.
Chloro boron-subphthalocyanine (sub PC) is one of promising organic solar materials. Diverse sub PC-based derivatives have been synthesized and proposed. In the present work, we theoretically suggest new inorganic-organic hybrid materials, i.e. sub PC derivatives with the ortho and Meta peripheral substitution by high…
This paper presents the characterization of fiber morphology, fiber count and tenacity of polyethylene fiber which is made from plastic bag waste. Recycling plastic bag waste into textile fiber has not developed yet. Plastic bag waste was recycled into fiber by melt spinning using laboratory scale melt spinning equipm…
CVD diamonds with NV-centers (nitrogen vacancy centers) are now considered as the most promising solidstate media for the realization of component base for quantum information processing due to the unique properties of NV-center electronic transitions, which allow initialization and read-out of it`s spin state
The fluorocarbon (FC) films were deposited on polyethylene terephthalate (PET) fabrics by a magnetron sputtering method. Effects of sputtering parameters on the water-resistance, uvioresistance and morphology of the fluorocarbon films were investigated. Results indicate that the film thickness increases when the sputt…

Poly (N-isopropylacrylamide) (PNIPA)-clay nanocomposite hydrogels (NC gels) having small patterns of several hundred micrometers were prepared by photoinitiated radical polymerization with the use of a patterned photomask. The irradiated region of the obtained gels became more opaque than the masked region at temperat…
The fatigue life of austenitic stainless steel is significantly reduced in the environment of a pressurized water reactor (PWR). One of the methods for evaluating the environmental effect involves the use of the environmental correction factor (Fen) determined from the fatigue lives of the material in air and the PWR…
High-temperature oxidation behavior of Fe-Ni-Cr alloys with different Ni contents in air and steam at 700°C was investigated. Oxidation mass gain in steam was higher than that in air. In both atmospheres oxidation mass gain tended to decrease with increasing Ni content. However, the Ni concentration dependence of oxid…
The corrosion is a natural phenomenon which affects the productivity and safety of men and machines. Since the mild steel has wide application in almost all industries, and is more prone to corrosion, particularly in acid medium, the present work aims to study the corrosive behavior of mild steel in 0.1N H2SO4 medium…
Stepwise transient (SWT) and pulse transient (PT) methods are experimental techniques for measuring the thermal diffusivity and conductivity of solid materials. The contribution deals with some interesting aspects of the methods. The first is devoted to the study of the influence of the thermal resistance caused by th…
