Abstract A detonating explosive interacting with a deformable structure is a highly transient and non-linear event. In field blast trials of military vehicles, a standard procedure is often followed in order to reduce the uncertainties and increase the quality of the test. If the explosive is buried in the ground, the…
We report on the in-situ polymerization of 3T with Cu(ClO 4 ) 2 inside several host polymers such as Novolak-based negative-tone photoresist, polystyrene (PS), poly(4-vinylphenol) (P4VP), poly(methyl methacrylate) (PMMA), and poly(4-vinylphenol)- co -(methyl methacrylate) (P4VP- co -MMA) to form an interpenetrating po…
Sol gel technique in combination with spin coating method was utilized for the synthesis of silica thin films. Tetraethyl orthosilicate (TEOS) alkoxide silane precursor was used for one step synthesis of silica sol with 0.1M HCL as catalyst. Casting solution of silica sol was spin coated on glass substrate. The X-ray…
Strontium hexaferrite (SrFe12O19) particles were synthesised using the modified chemical coprecipitation method. The results indicated that a single strontium hexaferrite phase formed at low annealing temperature 800°C in the presence of surfactant or by oxalic acid addition. Sonochemical assisted coprecipitation rout…
Abstract The aim of this work was to characterize the fracture behavior of polyamide 6 (PA6) and PA6 reinforced with clay (organically modified montmorillonite) [PA6/OMMT] at different temperatures and under higher loading rate. Pure PA6 and PA6 with different amounts and two types of OMMT were investigated. The struc…
Abstract This article reports on a facile route for the preparation of polypyrrole–polyvinyl alcohol–graphite oxide nanocomposites through the polymerization of pyrrole with different concentration (wt%) of graphite oxide using ammonium persulfate as an oxidant. The synthesized nanocomposites were characterized by Fou…
Here we report on the metal–semiconductor junction characteristics of a semiconducting ZnO nanowire grown directly on a metallic graphene film. The extracted specific contact resistivity of the graphene–ZnO nanowire contact (1.5 × 10−5 Ω·cm2) is comparable to that reported for Al–ZnO contacts. Based on the assumption…
In this paper we report on bubble growth rates and on the statistics of bubble topology for the coarsening of a dry foam contained in the narrow gap between two hemispheres. By contrast with coarsening in flat space, where six-sided bubbles neither grow nor shrink, we observe that six-sided bubbles grow with time at a…
The synthesis and thermoluminescent characteristics of dysprosium-doped MgB4O7 are analyzed. The phosphor at different concentrations (0, 0.1, 0.5, 1, 2 and 4 mol%) of the dopant was prepared by the solution-assisted method. The magnesium borate compound was confirmed by X-ray diffraction. The annealing and dopant con…
Various 2-D patterns of copper sulfate pentahydrate (CuSO 4 ·5H 2 O) were spontaneously formed through crystal growth in a thin gelatin matrix on a glass plate. The form of the grown crystal changes from polyhedrons to irregularly branching morphologies with increasing the polymer density in the matrix. Characteristic…
Abstract The high electrically conductive carboxyl‐functionalized multiwalled carbon nanotubes (COOH‐MWCNTs) were used to combine with nonconducting polyimide (PI) to generate a PI/COOH‐MWCNTs membrane. PI served as a matrix to entrap COOH‐MWCNTs and hemoglobin (Hb). COOH‐MWCNTs can improve the conductivity of the com…
Abstract Fundamental shortcomings of ferroelectrics (FEs) are low induced strain and high electric field often required for practical application in actuation, sensors, and acoustics. Although domain engineered FE single crystals deliver an order of magnitude improvement, fatigue remains another drawback in achieving…
Flow in unsaturated porous media or in engineered microfluidic systems is dominated by capillary and viscous forces. Consequently, flow regimes may differ markedly from conventional flows, reflecting strong interfacial influences on small bodies of flowing liquids. In this work, we visualized liquid transport patterns…
Abstract The influence of melt mixing conditions on the level of dispersion and the aspect ratio of vapor grown carbon nanofibers (VGCNFs) in a polystyrene (PS) matrix was studied. Final electrical and electromagnetic shielding capabilities in the 0.05–1.5 GHz frequency range are reported and discussed in the light of…
The removal of lithium and other group I contaminants from hydrothermally grown ZnO results in significant changes in its electrical, optical, and device characteristics. A significant reduction in donor compensation allows the fabrication of low series resistance Schottky contacts with extremely high rectification ra…
Based on the concepts of artificially microstructured materials, i.e. metamaterials, we present here the first practical realization of a radial wave crystal. This type of device was introduced as a theoretical proposal in the field of acoustics, and can be briefly defined as a structured medium with radial symmetry,…
Alkali‐based barium borosilicate glasses having similar composition to the Trombay nuclear research reactor waste base glass containing iron were prepared and irradiated by gamma rays. The radiation‐induced defect centers were investigated using electron paramagnetic resonance ( EPR ) technique. The results showed the…
This paper addresses the critical issues associated with using conventional bioimplants (stainless steel, cobalt–chromium and titanium alloy), and it emphasises on Mg as a potential material for fabricating load bearing bioimplants (hip, knee, shoulder and elbow). Hydroxyapatite (HAp) is a well established biodegradab…

The applicability of the computational docking approach was investigated to create a novel method for quick additive screening to inhibit the crystallization taking place in amorphous drugs. Surface energy and attachment energy were utilized to recognize the morphologically most important crystal faces. The surfaces (…
