The effects of 2-D hexagonal-lattice TiO2photonic crystal layers on the directional light extraction efficiency of low-scattering (Y1-xCex)3Al5O12(YAG:Ce3+) ceramic converters have been investigated. The hexagonal-lattice TiO2patterns were fabricated by an electron beam lithography process. The optimized yellow direct…
Fe 76 Si 9 B 10 P 5 /Zn 0.5 Ni 0.5 Fe 2 O 4 amorphous composite with micro-cellular structure and high electrical resistivity was prepared by spark plasma sintering (SPS) at 487 °C. XRD and SEM results showed that the Fe 76 Si 9 B 10 P 5 alloy powders remained the amorphous state and the composite was dense. A fusion…
The classical view of nerve growth factor (NGF) action in the nervous system is linked to its retrograde axonal transport. However, almost nothing is known on the trafficking properties of its unprocessed precursor proNGF, characterized by different and generally opposite biological functions with respect to its matur…
A major factor contributing to the failure of orthopedic and orthodontic implants is post-surgical infection. Coating metallic implant surfaces with anti-microbial agents has shown promise but does not always prevent the formation of bacterial biofilms. Furthermore, breakdown of these coatings within the human body ca…
Iron carbide (Fe 3 C) nanoparticles have been successfully synthesized by combining low‐temperature combustion synthesis method with carbothermal reduction. A homogeneous precursor powder (Fe 2 O 3 + C) derived from iron nitrate, glycine, and glucose mixed solution was subsequently calcined under nitrogen at 450°C–700…
In this study, aluminium-silicon carbide (Al-SiC) metal matrix composites (MMCs) of different compositions were prepared under different compaction loads. Three different types Al-SiC composite specimens having 10%, 20% and 30% volume fractions of silicon carbide were fabricated using conventional powder metallurgy (P…
A suite of Ti-bearing garnets from magmatic, carbonatitic, and metamorphic rocks was studied by electron probe microanalysis (EPMA), X-ray powder diffraction (XRPD), single-crystal X-ray diffraction (SCXRD), Mössbauer spectroscopy, and secondary ion mass spectrometry (SIMS) to better characterize their crystal chemist…
Energetic materials are substances that can undergo rapid, exothermic reactions when subjected to an external stimulus, such as heating. In this work, we show that the well-known Peng–Robinson equation of state can be applied to energetic materials, whether they are pure components, liquid mixtures, or solid mixtures.…
OBJECTIVES: The study aims at applying pharmaceutical nanotechnology and D-optimal fractional factorial design to screen and optimize the high-risk variables affecting the performance of a complex drug delivery system consisting of glimepiride-Zein nanoparticles and inclusion of the optimized formula with thermorespon…
Through empirical observations, sodium (Na) has been identified as a benign contaminant in some thin-film solar cells. Here, we intentionally contaminate thermally evaporated tin sulfide (SnS) thin-films with sodium and measure the SnS absorber properties and solar cell characteristics. The carrier concentration incre…
Objective: This present study aims to produce cocrystal of paracetamol (PCA)-dipicolinic acid (DPA) using supercritical antisolvent (SAS) cocrystallization process in order to improve tabletability profile of PCA. Methods: The PCA-DPA cocrystal prepared by SAS cocrystallization were compared to those produced using a…
Aberration-corrected microscopy in a scanning transmission electron microscope requires the fast and accurate measurement of lens aberrations to align or 'tune' the corrector. Here, we demonstrate a method to measure aberrations based on acquiring a 4D data set on a pixelated detector. Our method is compared to existi…
An aligned hydrogel with tunable macropore size via hot ice template is described, which exhibits a high porosity, large pore size, easily modified surface, high survival rate as well as a linear arrangement of NIH3T3 cells.
This article deals with the thermoelastic damping problem in a functionally graded (FG) Timoshenko microbeam. Thermal and mechanical properties of the microbeam vary in the thickness direction according to the power law relation. Employing Timoshenko beam theory, the governing dynamic equation coupled with thermal eff…
In this study, the effect of corrosion on the static behavior of stud shear connectors was investigated. Two series of push test specimens having different stud diameters were fabricated according to Eurocode 4. The test specimens were first corroded to different corrosion rates by electronic accelerating method. Stat…
The advent of friction stir welding (FSW) in 1991 has been evolutionary in the joining of metals and related materials. Friction stir welding has enabled the joining of metals that could not be joined by other welding processes. Research has shown that dissimilar materials with very different properties, plastics, com…
Nanotechnology is a most promising field for generating new applications in medicine, although, only few nano products are currently in use for medical purposes. A most prominent nanoproduct is nanosilver. Nano-silver has biological properties which are significant for consumer products, food technology, textiles, and…
So far, coumarin dyes have been extensively studied with various means to understand their photophysical behaviors and photochemical properties. Here, our performing time-dependent density functional theory calculation is aimed at exploring the excited-state hydrogen bonding dynamics of coumarin 153 (C153) in protic e…
Control of zero-field spin splitting is realized in a dual-gated high-quality InAs-AlSb two-dimensional electron gas. Magnetotransport experiments showed clean Shubnikov--de Haas oscillations down to low magnetic fields, and the gate-tuned electron mobility exceeded $700\phantom{\rule{0.16em}{0ex}}000\phantom{\rule{0.…
Implant failure due to poor integration of the implant with the surrounding biomaterial is a common problem in various orthopedic and orthodontic surgeries. Implant fixation mostly depends upon the implant surface topography. Micron to nanosize circular-shaped groove architecture with adequate surface roughness can en…
