Polymer nanocomposites represent a class of materials that have assumed great importance in recent years and are the focus of extensive research. Unlike plastomer nanocomposites, the elastomer nanocomposites are in the stage of infancy in respect to their applications. In general, in polymer composites, the matrix and…
In this study corrosion rates of aluminum, copper, brass and Stainless Steel 304 (SS 304) in tequila are reported from potentiodynamic polarization and Electrochemical Impedance Spectroscopy (EIS) measurements. A simple kinetic model is proposed to analyze the polarization data and to establish a comparison with EIS m…
In this work, electric transport properties of CaCu3Ti4O12 (CCTO) thin films were investigated for resistive switching, rectifying and gas sensor applications. Single phase CCTO thin films were produced by polymeric precursor method (PPM) on different substrates and their electrical properties were studied. Films prod…
We studied the ferroelectric properties of GeTe and Ge2Sb2Te5 thin films through the analysis of capacitance-temperature, contact resonance piezoresponse force, resonance tracking piezoresponse force, and switching piezoresponse force microscopy measurements. These alloys are non-typical ferroelectric materials with l…
The corrosion inhibition of carbon steel (CS) using the “green” inhibitor, polyvinyl pyrrolidone (PVP) was investigated. This study was conducted at pH 7 and pH 8 in an aerated medium containing 0.1 M NaCl. The effects caused by some additives (KI and untreated clay) were investigated. The study was done over a range…
Nd-doped BiFeO 3 (BNF) thin films were fabricated on SrRuO 3 (SRO)-coated (100) Nb-doped SrTiO 3 substrates by pulsed laser deposition, and nondoped BiFeO 3 (BFO) thin films were also fabricated similarly for comparison. Then, Nd-doping effects on ferroelectric and photovoltaic properties were evaluated. Polarization-…
Thermoelectric generators (TEGs) can harvest thermal energy producing electrical power from a temperature gradient. They are often employed in dynamic thermal environments, therefore it is important to quickly and precisely track the best operating point to maximize the power production. This paper presents an innovat…
In this work, one-pot hydrothermal method was used for modifying a wood surface by the deposition of TiO 2 /ZnO coating at a relatively low temperature. The prepared wood samples were characterised using SEM, energy dispersive X-ray analysis and powder X-ray diffraction. Results showed that wood surface was coated by…
Both carbon nanotubes (CNTs) and graphene nanosheets (GNs) have potential applications in polymer composites. Combining them may induce a synergistic effect on enhancing the properties of composites. Herein, CNT-GN 3D hybrids were prepared by liquid injection chemical vapor deposition through a spray containing both c…
In this work, we present a systematic study on the complete control over the sphere diameters of MCM-41 nanospheres with different pore sizes. The mesoporous silica nanospheres with diameter range from 40 nm to 160 nm are synthesized by using cationic quaternary ammonium surfactants as template and TEOS as silicon sou…
Abstract In this work, a detailed structural and spectroscopic study of nanocrystalline diamond (NCD) thin films grown by a continuous bias assisted CVD growth technique is reported. This technique allows the tuning of grain size and phase purity in the deposited material. The crystalline properties of the films are c…
We discuss general limitations of topographical studies of epitaxial graphene in ambient conditions, in particular, when an accurate determination of the layers thickness is required. We demonstrate that the histogram method is the most accurate for measurements of small vertical distances (<0.5 nm) and general…
Abstract Summary: This work intends to promote the use of natural fibers by comparing the behavior of isophthalic polyester matrix composites reinforced with unidirectional curaua fibers with that of unidirectional glass fiber composites. The composites were produced varying the reinforcement angle (0°, 15°, 30°, 45°,…
The static domain structures and local switching behavior of relaxor ferroelectric 0.29Pb(In1/2Nb1/2)O3-0.44Pb(Mg1/3Nb2/3)O3-0.27PbTiO3 single crystals at three crystal orientations are studied using piezoresponse force microscopy (PFM). PFM domain imaging shows that both the [001] and [111] oriented crystals exhibit…
The polycrystalline sample of complex tungsten-bronze type compound (Na 2 Pb 2 La 2 W 2 Ti 4 Ta 4 O 30 ) was prepared by a high-temperature solid-state reaction technique. Room temperature preliminary structural study using X-ray diffraction (XRD) data exhibits the formation of a single-phase new compound. The SEM mic…
Abstract Diamond nanophotonics have evolved tremendously from the study of color centers in bulk single crystals and nanocrystals to their characterization in nanostructured environments. This development was facilitated by the ability to generate monolithic, sophisticated nanodevices in high quality single crystal di…
Since the implantation of the first artificial aortic heart valve by Hufnagel et al., the design and construction of heart valve prostheses has undergone continuous and drastic changes to improve t...
Abstract Summary: In this study cellulose nanowhiskers were obtained from balsa wood. For this purpose, fibers of balsa wood were exposed to hydrolysis reactions for lignin and hemicellulose digestion and acquisition of nano‐scale cellulose. Transmission electron microscopy (TEM) results demonstrated that the obtained…
