The paper is devoted to experimental investigation of the spatial distribution of electromagnetic field in the vicinity of the tapered wire medium formed by copper wires conductors in the millimeter waveband. The technique of small perturbations was applied to analyze the spatial distribution of the field intensity in…
This article reviews the synthesis of Si-B-C-N ceramics, and the characteristics and principle of fabricating Si-B-C-N ceramics by using different precursors. So far, there only have two reports on preparation of Si-B-C-N ceramics, which are precursor pyrolysis and mechanical alloying. Therefore, this paper mainly dis…
Light matter interactions have led to a great part of our current understanding of the universe. When light interacts with matter it affects the properties of both the light and the matter. Visible light, being in the region that the human eye can "see," was one of the first natural phenomenon we used to learn about o…
The importance of NFC (Natural Fiber Composite) as construction materials is widely accepted all over the world. But it seems that NFC manufacturers have complicated information about the effect of ingredients to their products. Hence systematic study for optimum composition of NFC is needed. This study is aimed to el…

In this work, multimodal nonlinear microscopy of suspended CNTs using circular polarizations (CP) was reported. Significant variations in the SHG and THG signals of the CNTs between left hand circular polarization (LHCP) and right hand circular polarization (RHCP) were observed. The variations in the nonlinear signals…
Abstract : The Glass Failure Prediction Model (GFPM) is the basis for ASTM E1300 which is used across the nation for window glass design. ASTM E1300 states that the model is valid only for annealed (AN) glass but, ASTM E1300 does incorporate heat strengthened (HS) or fully tempered (FT) glass through the use of multip…
Whereas multiple scattering and shock wave formation are known to be antagonistic phenomena, this work concentrates on the interaction of an ultrasonic shock wave with a random multiple scattering medium. The shock wave is generated by long distance propagation of a short pulse (four periods at a 3.5 MHz central frequ…
Indium tin oxide (ITO) thin films were deposited onto glass substrates by RF magnetron sputtering to study variation of grain growth in pure argon and 99% argon plus 1% oxygen at different substrate temperatures. The average grain size increased with the increasing substrate temperature in pure argon. However, in oxyg…
Calcium hydroxides (Ca(OH)2) nanostructures have been fabricated through simple facile solution based synthesis at different temperatures 35,45 and 55°C repectively.Ethanol was utilized as a medium for reaction. The synthesized powder was characterized by Field Emission Scanning Electron Microscope (FESEM SUPRA 35VP Z…
Shock loading of natural pyroxenite samples and synthetic pyroxene samples sintered from a mixture of oxides with stoichiometry Mg 0.9 Fe 0.1 SiO 3 was investigated. X-ray analysis of the recovered material was performed. Particle velocity profiles recorded by laser interferometry indicate the existence of a phase tra…
In this study the different finesses degree of the pulverized Eupatorium Adenophorum (EA) was evaluated as potential raw materials for the low-cost hydrogels whose the swelling behaviors were compared and studied at the same graft-copolymerization condition. The results are shown that the absorbency of EA hydrogels in…
Al:ZnO thin films were deposited using the radio frequency magnetron sputtering technique at various temperatures and sputtering powers. With the increase in the deposition temperature and the decrease in the radio frequency sputtering power, the crystallinity was increased and the surface roughness was decreased, whi…
The flow behavior and microstructural evolution of an as-wrought duplex stainless steel has been investigated by Gleeble-3500 thermal-mechanical simulator within the temperature range of 950-1200°C and the strain rate range of 0.1-10s-1. The flow curves exhibited a peak stress characteristic followed by dynamic soften…
The applied pressure resulting in an explosion in the case of shock-induced shear is demonstrated to depend on the shear area [area of the contact of the high explosive (HE) with the metal surface]. The dependence of the probability of an explosion of the HE (phlegmatized HMX and PETN) compressed between two steel pla…
The present contribution reports on the modelling, fabrication, as well as the intra-cavity characterization of fully dielectric grating-mirrors for Yb:YAG thin-disk lasers. By integrating a low-index leaky-mode waveguide and a sub-wavelength diffraction grating onto an HR mirror, such devices achieve high diffraction…
Apodized focusing subwavelength gratings which can couple both transverse electric (TE) and transverse magnetic (TM) modes are presented. The coupling efficiencies were -3.0 dB and -4.0 dB for TM and TE modes, respectively.
In this paper, 2-phenyl imidazole (2-PZ) microcapsule-type curing agent of epoxy resin were prepared through solvent volatilization with 2-PZ and polymethyl acrylic glycidyl ester (PGMA) as the raw materials. The micro-morphology, shape and structure of the microcapsules were studied by scanning electronic microscope…
This case study describes Microchip's experience with perfluoroelastomers o-ring seals.
We investigated the changes in the preferred orientation and microstructure of ZnO:In films with increasing In content. ZnO and ZnO:In films with In contents of up to 50 at.% were deposited on Si (111) substrates by using pulsed laser deposition and were subsequently characterized using X-ray diffraction (XRD), atomic…
