In this work we describe the observations of structural transitions in ferronematics based on the thermotropic nematics 6CHBT (4-trans-4'-n-hexyl-cyclohexyl-isothiocyanato-benzene). The ferronematic droplets were observed in solutions of nematogenic 6CHBT dissolved in phenyl isocyanate and doped with fine magnetic par…
When a liquid drop is confined between an elastic plate and a rigid substrate, it spreads spontaneously due to the effects of interfacial forces, eventually reaching an equilibrium shape determined by the balance between elastic and capillary effects. We provide an analytical theory for the static shape of the sheet a…
In-doped SnO2 microtubes as well as Sn-doped In2O3 (ITO) nano- and microislands have been grown by thermal treatment of compacted SnO2–In2O3 powders under argon flow at 1350 °C in a catalyst-free process. The SnO2 tubes contain about 1 at. % of In, even when the In content in the starting mixture was as high as 52 at.…
Nanocrystalline metallic Pd films have been produced by thermolysis of Pd hexadecanethiolate deposited on a Si surface. The particle size was in the range of 50-60 nm based on electron and atomic force microscopy. The Pd surface produced was found to be surface-enhanced Raman scattering (SERS) active with an enhanceme…
In this paper we report the fabrication of a multivalent, cell-type specific and cytoplasmic delivery system based on single-walled carbon nanotubes. The latter were functionalized through adsorption of phospholipids terminated by biotinylated PEG chains functionalized with fluorochrome-coupled neutravidin, and subseq…
In this paper, we present quantitative analyses of the impact of Joule heating on the package level electromigration (EM) test of copper dual damascene (DD) interconnects with linewidths of 0.28 and 0.7 μm. A total of 120 samples are tested with a maximum current density of 8 MA/cm2. It is found that high test current…
The authors investigated a full sealed flat-panel light source, which is based on a triode structure with a metal mesh gate electrode and uses a carbon nanotube cold cathode. It has a flat surface luminance distribution with good uniformity, a stable luminance of 12000cd∕m2, and a luminous efficiency that was measured…
Nanostructured electronic and photonic devices include a high density of material interfaces, which can strongly impede heat conduction and influence performance and reliability. Thermal conduction through interfaces is a very mature discipline for the traditional geometry, in which the lateral interface dimensions ar…
Abstract Nanoparticles of tin oxide, doped with Ce and Y, were prepared using the polymeric precursor method. The structural variations of the tin oxide nanoparticles were characterized by means of nitrogen physisorption, carbon dioxide chemisorption, X-ray diffraction, and X-ray photoelectron spectroscopy. The synthe…
Bottom-up growth of carbon nanotubes (CNTs) and electrochemical plating approaches were combined to produce homogeneous copper/CNT composite. The measured resistivity of the copper/CNT composite at room temperature was 2.2 muOmegaldr cm. The electrical resistivity of copper/CNT composite at room temperature increases…
In this study, we have prepared PLGA (poly-D,L-lactide-co-glycolide) nanospheres loaded with biocompatible magnetic fluid and anticancer drug taxol by a modified nanoprecipitation technique and investigated their magnetic properties. A magnetic fluid, MF-PEG, with a biocompatible layer of polyethylene glycol (PEG), wa…
The effects of filler loading and immersion in water on the creep/ recovery behavior of composites made from MDF (medium density fiberboard) flour (as natural fiber) and recycled HDPE (high density polyethylene) (as resin) were studied (at 60, 70, and 80% by weight fiber loadings). Nominal density and dimensions of th…
The phase composition, the structural parameters, and the basic magnetic characteristics of a number of nanosized powders of simple spinel ferrites produced by the method of mechanochemical reactions from salt systems were studied. The influence of size and surface effects on the saturation magnetization and magnetic…
“Glass”, a frozen disordered-state, has been found in areas as diverse as amorphous solids, magnetic alloys, ferroelectrics, superconductors, and even in models of biological evolutions. In the present review we introduce a new class of glass–the “strain-glass”, which was discovered very recently. Strain glass is deri…
High-temperature and high-pressure behaviours of β-Ga 2 O 3 powder are studied by energy-dispersive x-ray diffraction in a diamond anvil cell (DAC). It is found that the phase transition from the monoclinic β-Ga 2 O 3 to the trigonal α-Ga 2 O 3 occurs at around 19.2 GPa under cold compression. By heating the powder to…
Quantitative analysis of the fission gas release characteristics during the voloxidation and oxidation and reduction of oxide fuel (OREOX) processes of spent pressurized water reactor (PWR) fuel was carried out by spent PWR fuel in a hot cell of the DUPIC Fuel Development Facility. The release characteristics of 85Kr…
Ferroelectric 1 mol.% La(3)+ and 0.5 mol.% Fe(3)+ codoped Pb[Zr0(0.54)Ti0(0.46)]O(3) ceramics were studied by means of multifrequency electron paramagnetic resonance (EPR) spectroscopy. The obtained results prove that iron is incorporated at the [Zr,Ti]-site, acting as an acceptor and building a charged Fe'(Zr,Ti) - V…
The stability of intrinsic and Al-doped single- and bilayer ZnO for thin-film CuInGaSe2solar cells, along with Al-doped Zn1−xMgxO alloy and Sn-doped In2O3(ITO) and F-doped SnO2, was evaluated by direct exposure to damp heat (DH) at 85°C and 85% relative humidity. The results show that the DH-induced degradation rates…
Abstract The electron density distribution of a light-induced molecular excited state, i.e. the high spin metastable state of [Fe(phen) 2 (NCS) 2 ], was determined from steady-state photocrystallographic measurements. We defined the experimental conditions under which the accuracy of the measured diffraction data is c…
The crystal structure of Al 4 B 2 O 9 , synthesized from Al(NO) 3 ·9H 2 O and B(OH) 3 via a sol-gel process, is studied and characterized by Rietveld refinements and grid search analyses combined with 11 B and 27 Al MAS NMR spectroscopy. The aluminum borate with a unit-cell composition of Al 32 B 16 O 72 is closely re…
