The influence of the topographic morphology of poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBHHx) films on human mesenchymal stem cells (hMSCs) was investigated in this study. PHBHHx films with various surface characteristics were prepared by compression-molding, solvent-casting and electrospinning. The adhesion,…
We have proposed and developed a low temperature thermoelectric generator (TEG) using engine water coolant of light-duty vehicles. Experimental results from test vehicle, of which engine size is about 2.0 liters, show that fabricated prototype Thermoelectric Generator generates more than 75W for driving condition of 8…
Lattice rotations in graphene on Ru(0001) are investigated with low-energy electron microscopy and micro-low-energy electron diffraction. The measurements place an upper limit, 250 nm, on the racemic length scale of the recently reported chirality in this system, arising from rotated features within the unit cell. On…
Abstract: MnFe2O4 is one of the most common spinel ferrites and its nanoparticles have found applications in various applications. In this paper, we report the preparation of MnFe2O4 nano-crystalline spinel particles by different techniques viz., low temperature combustion technique using urea, glycine and glucose as…
Abstract Taking the desirable attributes of CVD and aqueous plating techniques while minimizing the disadvantages of each, supercritical fluid chemical deposition (SFCD) demonstrates itself to be a promising process alternative to enable the fabrication of nanostructured devices. This paper gives information about the…
Essential oil of aerial parts of Pulicaria mauritanica was obtained by hydrodistillation and analyzed by GC and GC/MS. This oil was tested as corrosion inhibitor of mild steel in 0.5M H2SO4 using weight loss measurements, electrochemical polarization and EIS methods. The analysis of P. mauritanica essential oil allowe…
The electric double layer capacitor (EDLC) is considered to be one of the promising systems for electric energy storage. Both the optimization of the micropore structure of the activated carbon electrode and the higher voltage operation of the EDLC are necessary for improving the energy density of the EDLC. Thus, ther…
[1] We report on measurements of the flow pattern and in-situ saturations whenn-octane displaces a brine in which surface treated silica nanoparticles are dispersed. The nanoparticles are known to stabilize octane-in-water emulsions. We find that the displacement front is more spatially uniform, and with a later break…
Structural parameters of a range of over 100 meso-substituted zinc porphyrins were reviewed and compared to show how far the nature of the functional group may affect the interatomic distances and bond angles within the porphyrin core. It was proved that even despite evident deformations of the molecular structure, in…
BACKGROUND: Previous benefit-risk perception studies and social experiences have clearly demonstrated that any emerging technology platform that ignores benefit-risk perception by citizens might jeopardize its public acceptability and further development. The aim of this survey was to investigate the Italian judgment…
Transmission electron microscopy was performed on a carbon‐containing SiOC material derived from a polymer precursor pyrolyzed at 1100°C and subsequently annealed at 1400°C. The TEM study focused on the correlation between micro/nanostructure evolution and the piezoresistivity monitored on the annealed sample. Upon py…
Strong luminescence peaks were observed at 700 and 800 nm in undoped yttrium aluminum garnet (YAG) single crystals. They were attributed to low level of iron impurities as confirmed by Glow Discharge Mass Spectrometry analysis. The 800 nm was only excited by high energy band at 270 nm; the reason behind that was discu…
Raman scattering (including nonresonant, resonant, and surface enhanced scattering) of light by optical and surface phonons of ZnO nanocrystals and nanorods has been investigated. It has been found that the nonresonant and resonant Raman scattering spectra of the nanostructures exhibit typical vibrational modes, E 2(h…
The temperature dependent electrical and thermal properties including electrical resistivity (ρ), specific heat (CP), Seebeck coefficient (S) and thermal conductivity (κ) have been studied for the polycrystalline NiTi, Ti50Ni40Cu10 and Ti50Ni48.5Fe1.5 shape memory alloys from 10–400 K. It was found that the electrical…
The influence of crosslink agents on properties of modified-NRs was investigated. The results prove that the presence of oxirane rings and/or chlorine atoms on the ENR and CENR molecules prominently affects on overall studied properties of the vulcanized rubbers. Crosslink agents also play significant role on Mooney v…
Electrical discharge characteristics of micro-gaps, ranging from 50 to 1000 μm in air are investigated under ac, dc and high frequency (5 kHz) by using blade electrodes that possess a high aspect ratio: 20 μm edge thickness and 15 mm length. Three micro-gap configurations (single, series and parallel) are studied for…
We investigate the effects of vacancy defects on the electronic and transport properties of carbon nanotubes through density functional calculations. In both cases, where vacancies aggregate into larger clusters and are disordered, conductance changes from metallic to insulating regime, while their origins are differe…
In:ZnO nanoparticles are prepared by the sol—gel process. The ratios of In/(Zn+In) are 0%, 5%, 8%, 10%, and 15%, respectively. Crystal phase structures and optoelectronic properties of these samples are characterized and the chromaticity coordinates of different samples are also calculated in CIE—XYZ colour system. Th…
New solid electrolytes with a high conductivity by K+ ions in the K1 − 2x Sr x GaO2 system are synthesized and studied. It is found that the introduction of Sr2+ ions into potassium monogallate leads to the formation of solid solutions with KGaO2 structure in a wide range of additive concentration. These solid solutio…
Using microwave irradiation as an intercalation method, quaternized chitosan/ organo – montmorillonite (QCS/OMMT) nanocomposites were prepared rapidly by intercalating quaternized chitosan (QCS) into the interlayer of organo – montmorillonite (OMMT) in 70 min. The structure and morphology of QCS/OMMT nanocomposites we…
