The structural, optical and electrical properties of spray deposited antimony (Sb) doped tin oxide (SnO2) thin films, prepared from SnCl4 precursor, have been studied as a function of antimony doping concentration. The doping concentration was varied from 0 to 1.5 wt.% of Sb. The analysis of x-ray diffraction patterns…
We report a comprehensive density functional theory (DFT) + $U$ study of the energetics of charged and neutral oxygen defects in both PuO$_{2}$ and $α$-Pu$_{2}$O$_{3}$, and present a quantitative determination of the equilibrium compositions of reduced PuO$_{2}$ (PuO$_{2-x}$) as functions of environmental temperature…
A recent inelastic x-ray scattering study [Manley et al., Phys. Rev. B 85, 132301 (2012)] reveals that the phonon dispersion curves of PuO2 is considerably consistent with our previous density functional +$U$ results [Zhang et al., Phys. Rev. B 82, 144110 (2010)]. Here in the present work, using the same computational…
In the first paper of this series [S. Torquato, J. Chem. Phys. {\bf 136}, 054106 (2012)], analytical results concerning the continuum percolation of overlapping hyperparticles in $d$-dimensional Euclidean space $\mathbb{R}^d$ were obtained, including lower bounds on the percolation threshold. In the present investigat…
Noncentrosymmetric quaternary sulfides, ACd 4 Ga 5 S 12 (A = K, Rb, Cs) have been synthesized by a modified reactive flux method with high yields. Single-crystal X-ray diffraction analyses revealed they adopted a known KCd 4 Ga 5 S 12 -structure type in the trigonal space group R 3 (No. 146) with cell parameters of a…
We demonstrated the first application of a pyroelectric nanogenerator as a self-powered sensor (or active sensor) for detecting a change in temperature. The device consists of a single lead zirconate titanate (PZT) micro/nanowire that is placed on a thin glass substrate and bonded at its two ends, and it is packaged b…
In this study, a novel approach is demonstrated to fabricate hierarchically structured cadmium selenide (CdSe) layers with size-tunable nano/microporous morphologies achieved using polystyrene (PS) bilayered templates (top layer: colloidal template) via potentiostatic electrochemical deposition. The PS bilayer templat…
Over the years there have been many theories presented regarding corrosion of ductile iron pipe and the effectiveness of polyethylene encasement as a corrosion control measure. Sound corrosion engineering is based on corrosion science rather than theories. Some of the ductile iron corrosion theories and the relevant c…
The structure of Ceria doped Scandia Stabilized Zirconia (1Ce10ScSZ) electrolyte film deposited by EB-PVD (Electron Beam-Physical Vapour Deposition) technique on NiO-ZrO2 substrate was characterized by electron microscopy. The highly porous substrate was densely covered by deposited film without any spallation. The pr…
The aim of this study was to investigate the acute effects of nanosilver as potentially dangerous additives to assess the mortality effects of this nanotechnology product on one of the valuable and important species of Caspian Sea. We comparedthetoxicity ofdifferent sizedsilver nanoparticles(AgNPs)whicharebeingwidelyu…
Retrofit of pipes subjected to combined internal pressure and external loads results in designs that require installation of many layers of carbon fabric. Such repairs are very time-consuming and expensive. To overcome these shortcomings, the author has developed a new honeycomb-FRP pipe that is presented here. This m…
The crystal structure of tin (II) sulphate, SnSO 4 , was obtained by Rietveld refinement using synchrotron high-resolution powder X-ray diffraction (HRPXRD) data. The structure was refined in space group Pbnm . The unit-cell parameters for SnSO 4 are a = 7.12322(1), b = 8.81041(1), c = 5.32809(1) Å, and V = 334.383(1)…
Fluorescent reporters based on lanthanide ions, such as europium chelates, enable highly sensitive detection in immunoassays and other ligand binding assays. Unfortunately they normally require UV-excitation produced by a xenon flash or nitrogen laser light source. In order to use modern solid state excitation sources…
Abstract An interesting correlation between initial loading and nature of wrapping of regioregular poly(3‐hexylthiophene) (rrP3HT) on multiwalled carbon nanotube and their combined effect on dynamic‐ and thermomechanical properties in ternary system (thermoplastic polyurethane as matrix) is highlighted. Wrapping of rr…
In media with strong spatial dispersion, the electric displacement vector and the electric field are typically linked by a partial differential equation in the bulk region. The objective of this work is to highlight that in the vicinity of an interface, the relation between the macroscopic fields cannot be univocally…
Nanostructured porous oxides are produced by anodic dissolution of several metals. A scaling approach is introduced to explain pattern nucleation in an oxide layer, and a related microscopic model shows oxide growth with long nanopores. The scaling approach matches the time of ion transport across the thin oxide layer…
Potassium hexatitanate fibrous crystals have been synthesized by a conventional solid-state reaction and via molten salt process. The molten salt process has been shown to be effective in preparing fine and non-agglomerated K 2 Ti 6 O 13 whiskers. The type of molten salt (KCl, NaCl-KCl) has a significant effect on the…

Nuclear positions and anisotropic atomic displacement parameters (ADPs) of all the atoms are determined with high accu…
The effects of heteroatom‐containing ferrocene catalysts on the materials produced from chemical vapour deposition (CVD) floating catalyst synthesis were investigated. Specifically, the influence of nitrogen‐ and oxygen‐containing ferrocenoyl imidazolide and ( N ‐phenylcarbamoyl)ferrocene, and sulfur‐ and oxygen‐conta…
