A simple, efficient and quick method has been established for the synthesis of CePO(4):Tb nanorods and CePO(4):Tb/LaPO(4) core/shell nanorods via ultrasound irradiation of inorganic salt aqueous solution under ambient conditions for 2 h. The as-prepared products were characterized by means of powder x-ray diffraction…
Energy transfer from host excitation at $\ensuremath{\lambda}\ensuremath{\sim}160\phantom{\rule{0.3em}{0ex}}\mathrm{nm}$ to ${\mathrm{Gd}}^{3+}$ impurity ions was observed in yttrium and scandium borates and phosphates. The fluorescence and excitation spectra, as well as time-resolved fluorescence data were obtained.…
This paper presents experimental S-parameter data (amplitude and phase) in the 8–26GHz range for split-ring resonator (SRR) metamaterial samples exhibiting electric (E) and/or magnetic (H) resonances at 10.4GHz depending on the orientation of the gaps of the SRRs with respect to the E and H fields. Use of a thru, refl…
Coupled equations describing the radial and translational dynamics of an encapsulated gas bubble in an ultrasound field are derived by using the Lagrangian formalism. The equations generalize Church's theory by allowing for the translation motion of the bubble and radiation losses due to the compressibility of the sur…
Amorphous mesoporous aluminophosphates (AlPO) with P/Al molar ratio in the range 0.8-1.15 are synthesized by using the citric acid (CA) route and are systematically characterized using N(2)-adsorption, XRD, SEM, solid-state CP-MAS NMR, FT-IR, TG-DTA, CO(2)-TPD, and NH(3)-TPD. The characterization studies show that the…
Preferentially aligned silver nanorod arrays prepared by oblique angle vapor deposition were evaluated as substrates for surface-enhanced infrared absorption (SEIRA) spectroscopy. These nanorod arrays have an irregular surface lattice and are composed of tilted, cylindrically shaped nanorods that have an average lengt…
Iron(II) poly(pyrazolyl)borate complexes have been investigated to determine the impact of substituent effects, intramolecular ligand distortions, and intermolecular supramolecular structures on the spin-state crossover (SCO) behavior. The molecular structure of Fe[HB(3,4,5-Me3pz)3]2 (pz = pyrazolyl ring), a complex k…
Laponite clay was modified with combinations of organic ammonium surfactant and/or covalently bound poly(methyl methacrylate) (PMMA). Two polymer attachment methods were explored, one through reaction of a methacrylate compound with the clay's silanol group followed by in situ free-radical polymerization of methyl met…
Digital woven textiles are one of the latest research areas of digital textiles. The key of research on design of digital woven fabrics lies in structural design. Nowadays, the application of digital design technology has fundamentally changed the concept of structural design of woven fabric, giving rise to design met…
We present an atomic-level criterion for material stability in an atomic system. The criterion draws on the strong ellipticity condition in continuum elasticity theory; however, it is formulated directly in terms of atomic potential without resorting to the continuum concepts. Since the criterion is based on local ene…
A series of styrene-butadiene-rubber (SBR) composites have been vulcanized with different weight ratios of general purpose furnace carbon black, viz., 10, 30, 50, 70, and 90%. The compounded SBR composites have been characterized for physicomechanical properties, such as surface hardness, tensile strength, percentage…
Potassium (K) deficiency is emerging in intensively cropped soils of Kenya, but the magnitude of the problem has not been determined. This study was conducted to ascertain the possibilities of mapping K-deficient soils by the use of existing soil and climatic databases and validate the developed map. Mapping was done…
Nd8.1Dy0.9Fe76.95Co8.55B5.5 nanocomposite magnets annealed with and without a 10 T magnetic field were investigated in this article. The ribbons with coexisting amorphous and crystalline phases were selected to do this study. The results of Mössbauer spectroscopy revealed that the content of α-Fe increased when anneal…
In this work, we report a systematic study of the oxygen nonstoichiometry, high-temperature thermodynamics, and transport properties of the perovskite-related mixed conductor Sr 3 FeMO 6+ δ (M = Co, Ni). Thermogravimetry was used to determine the oxygen content change (6+δ) as a function of temperature ( T ) and equil…
The influence of partial fluorination on the lithographic performance of photoresists based on (meth)acrylate terpolymers containing polyhedral oligomeric silsesquioxane (POSS) pendant groups is investigated in bilayer schemes for 193 nm lithography. For the first time the capability of POSS-functionalized resists for…
For more than a decade, Tissue Engineering has been devoted to the reporting and discussion of scientific advances in the interdisciplinary field of tissue engineering. In this study, 779 original articles published in the journal since its inception were analyzed and classified according to different attributes, such…
We report on the magnetic properties of epitaxial La0.7Ba0.3MnO3 and La0.7Sr0.3MnO3 films on Si (100) and Si (111) substrates using SrTiO3 template layer, which demonstrate magnetic and electrical properties at and above room temperature. The magnetization data show magnetic transition and magnetic hysteresis at and a…
Abstract In reverse micelle systems, a large enhancement of the oxidation ability of dilute nitric acid was discovered, and its oxidation mechanism was explored. The Br− ion in the surfactant, CTAB, was oxidized to Br2 (or Br3−) in the CHCl3/CTAB/H2O reverse micelle system with W = 1.0–4.0 by diluted nitric acid (0.25…
This paper elucidates the effects of nucleating agents on the foaming behavior of polypropylene (PP) foams blown with butane in extrusion. The cell density was controlled by varying the talc content, and foam expansion was observed at a fixed blowing-agent content while varying the melt and die temperatures. As observ…
