Molybdenum oxide (MoO3) exhibits interesting structural, chemical, electrical, and optical properties, which are dependent on the growth conditions and the fabrication technique. In the present work, MoO3 films were produced by pulsed-laser deposition and dc magnetron sputtering under varying conditions of growth temp…
Antibody-conjugated iron oxide nanoparticles offer a specific and sensitive tool to enhance magnetic resonance (MR) images of both local and metastatic cancer. Prostate-specific membrane antigen (PSMA) is predominantly expressed on the neovasculature of solid tumors and on the surface of prostate cells, with enhanced…
Experiments are conducted to find out the tensile properties of short sun hemp, banana, and sisal fiber reinforced composites. Length of these natural fibers and fiber weight are varied and are impregnated in polyester resin to prepare tensile test specimen. Optimum values of fiber length and fiber weight ratios are f…
In this paper, polyethylene terephthalate (PET) and polypropylene (PP) non-wovens were modified by a dielectric barrier discharge in air, helium and argon at medium pressure (5.0 kPa). The helium and argon discharges contained a fraction of air smaller than 0.1 %. Surface analysis and characterization were performed u…
A Miniature cantilever-type ultrasonic motor was fabricated using multilayer piezoelectric ceramics (MLPC) made of (Sr,Ca) 2 NaNb 5 O 15 (SCNN), a Pb-free piezoelectric material, and the electrical driving properties were investigated. The displacement of SCNN-MLPC was 177 nm at 100 V, which was 10-fold the voltage of…
We report Monte Carlo (MC) simulation results showing applied bias dependent spatial velocity oscillations for semiconducting single-walled zig-zag carbon nanotubes (CNTs). MC simulations show velocity oscillations in CNTs at different lengths due to high scattering rates associated with optical phonon emissions in th…
High quality, c-axis oriented zinc oxide (ZnO) thin films were grown on silicon substrate using RF magnetron sputtering. Surface acoustic wave (SAW) devices were fabricated with different thickness of ZnO ranging from 1.2 to 5.5 μmUm and the frequency responses were characterized using a network analyzer. Thick ZnO fi…
A time-dependent study of the oxidative shortening of single-walled carbon nanotubes by concentrated nitric and sulfuric acids has been carried out. A polishing step using sulfuric acid and hydrogen peroxide was used to remove the amorphous carbon produced by the defect-creating oxidation treatment. An empirical relat…
Three areas of considerable progress are identified in the area of polymeric insulation since the mid 1990s (i.e. since the inception of the Eric O. Forster Memorial Lectures): the understanding of ageing, the measurement of space charge, and the development of nanodielectrics. The paper proposes a typology to disting…
A water-soluble halogenated porphyrin, namely 5,10,15,20-tetrakis(2-chloro-3-sulfophenyl)porphyrin (TCPPSO(3)H), was prepared and evaluated as sensitizer for photodynamic therapy (PDT). Photophysical properties of TCPPSO(3)H, such as high photostability, long triplet lifetime and high singlet oxygen quantum yield sugg…
The advent of sophisticated drug delivery strategies for cancer applications has inundated the scientific and clinical community with new tactics and approaches such as molecular targeting, nanotechnology-based methods and personalized therapies. Unfortunately, the clinical impact has been moderate at best, falling si…
(Mn, Zn) co-doped CdS (Cd 0.8 Mn 0.01 Zn 0.17 S, Cd 0.78 Mn 0.15 Zn 0.07 S, and Cd 0.67 Mn 0.3 Zn 0.07 S) nanowires (or nanobelts) were synthesized using the vapor transport method. Their X-ray diffraction patterns reveal a significant contraction of the lattice constants of up to 1.5%, due to the incorporation of Mn…
A series of Ni43Mn46−xCuxSn11 (x=1, 2, and 3) alloys was prepared by the arc melting method. The martensitic transition shifts to a higher temperature with increasing Cu concentration. The isothermal magnetization curves around the martensitic transition temperature show a typical metamagnetic behavior. Under a low ap…
The dehydration dynamics of the of the Ca-saturated <1 μm size fraction of SWy-1 (low-charge montmorillonite) were studied at the crystal scale under isothermal conditions using X-ray diffraction with a position-sensitive detector (XRD-PSD) in the 30.170 °C temperature range. A total of 630 XRD patterns were modele…
We report on the influence of polyanion molecular weight on the growth and structure of multilayered thin films fabricated from poly(allylamine) (PAH) and well-defined, end-labeled poly(acrylic acid) (PAA) synthesized by atom transfer radical polymerization. We observed striking differences in the growth of PAH/PAA fi…
We studied the thermoelectric properties of heavily Sn-doped ZrCoSb half-Heusler compounds, ZrCoSn x Sb 1- x ( x ≤0.15), to develop p-type thermoelectric materials. With increasing Sn content x , electrical resistivity decreased and the sign of the thermoelectric power changed from negative to positive. Thermal conduc…
A statistical mechanical theory is proposed for stress-induced acceleration of thermally driven barrier hopping and segmental relaxation, dynamic yielding and devitrification in polymer glasses. The approach is built on the concept of a nonequilibrium free energy determined by the amplitude of temperature-dependent co…
Barium hexaferrite BaFe 12 O 19 nanoparticles with a single‐domain size were synthesized using a controlled hydrothermal process involving the LaMer–Dinger principle and the Ostwald ripening mechanism. Nanocrystalline particles of BaFe 12 O 19 were obtained when the molar ratio of the precursor composition Ba(OH) 2 ·8…
This study explores the effects of hybridization of glass fiber on low velocity impact behavior and damage tolerance capability of woven jute fabric composite. Laminates were fabricated by the hand lay—up technique using a mold and cured under light pressure at room temperature. Low velocity impact tests were conducte…
The present work reports on the fabrication and characterization of a planar Peltier cooler on a flexible substrate. The device was fabricated on a 12 µm thick Kapton(c) polyimide substrate using Bi 2 Te 3 and Sb 2 Te 3 thermoelectric elements deposited by thermal co-evaporation. The cold area of the device is cooled…
