Corrosion behavior of Type 316L (UNS S31603) stainless steel piping used in integrated coal gasification combined cycle (IGCC) plant facilities processing coal (0.9 MPa to 1.1 MPa and 150°C to 300°C) and industrial waste (0.11 MPa and 40°C to 60°C) was explained using scanning electron microscopy-energy dispersive x-r…
Lange C-C-Bindungen: Die Analyse des Raman-Spektrums von K2[TCNE]2, das aus isolierten π-[TCNE]22−-Dimeren besteht (TCNE=Tetracyanoethylen), mit Anregung bei 1064 nm offenbart mehrere energiearme symmetrische intradimere Atmungsmoden bei 198, 173, 155, 131, 107 und 85 cm−1. Die Daten bestätigen eine lange Zwei-Elektro…
Atomistic simulation techniques are used to examine the stability of Ruddlesden–Popper (R–P) phases Sr ( n = 1, 2, 3, 4 and ∞). Various sets of empirical pair potentials are employed to determine the formation energies of the R–P phases. Formation energies are also calculated with Density Functional Theory (DFT). The…
Size, shape, nuclearity: Aberration-corrected scanning transmission electron microscopy was used to determine the 3D structures of MgO-supported Os3, Os4, Os5, and Os10 clusters, which have structures nearly matching those of osmium carbonyl compounds with known crystal structures. The samples are among the best-defin…
Abstract Alkali‐metal (Li, Na, K)‐doped lanthanum oxysulfide nanoplates were obtained in the hexagonal phase by thermolysis of metal acetylacetonates in organic solvents with high boiling points and sulfurization using sulfur powders. The characterization results showed that the size, shape, crystallinity, composition…
It is known that dissolved oxygen promotes stress corrosion cracking (SCC) of carbon steel in fuel-grade ethanol. The effects of oxygen on ethanol SCC were investigated using controlled-potential tests in deaerated simulated fuel-grade ethanol (SFGE) with supporting electrolytes. The effects of applied anodic potentia…
Energy transfer is mainly governed by the phonon transport in dielectric films. The polarization and dispersion of the phonons alter the thermal resistance of the film as the film size becomes comparable to the mean path of the substrate material. This is because of the quasi-ballistic behavior of the transport charac…
This study examines the corrosion behavior of aluminum alloys in condensed water containing different concentrations of anions for a heat exchanger in an automotive exhaust gas recirculation (EGR) system of a diesel engine. Electrochemical measurements and bulk analyses revealed that the aluminum alloy is protected by…
We report on a comprehensive investigation of the magnetic properties of [NdCo(bpdo)(H2O)4(CN)6]⋅3H2O (bpdo=4, 4'-bipyridine-N,N'-dioxide) by use of electron paramagnetic resonance, magnetization, specific heat and susceptibility measurements. The studied material was identified as a magnet with an effective spin S =…
Single-crystal diamond Schottky photodiodes have been developed following a WC-diamond-TiC/Ti/Ag vertical structure for X-ray dosimetry with characteristics of low leakage current and the capability of zero-bias operations. Continuous and modulated X-ray measurements show that the devices developed provide a linear re…
We report, for the first time, the synthesis of colloidal copper indium selenide (CuInSe2) nanocrystals (NCs) possessing a gradient stoichiometry that is potentially tunable by the presence of a conducting polymer, i.e., poly(3-hexyl thiophene) (P3HT) in the synthesis medium. Dibenzyl ether (DBE) was used as a reactio…
Self-assembled monolayers (SAMs) prepared from organic thiol molecules on metal substrates are known to exert substantial influence over mineralization and, as such, provide model systems for investigating the mechanisms of templated crystallization by organic matrices. Characterizing the structural evolution at the o…
Abstract We analyse two-dimensional clamped parallel elastic sheets which are partially immersed in liquid as a model for elasto-capillary coalescence. In the existing literature this problem is studied via minimal energy analysis of capillary and elastic energies of the post-coalescence state, yielding the maximal st…
We investigate magnetoinductive waves in two-dimensional periodic arrays of split ring resonators or capacitively loaded loops and characterize the modes with real and complex wavenumber excitable in such arrays. Each resonator is modeled as a single magnetic dipole, and the computation of the modal wavenumbers is per…
Temperature-dependent London penetration depth $\ensuremath{\lambda}(T)$ was measured in optimally doped $x=0.35$, as-grown [${T}_{c}\ensuremath{\approx}25$ K, $\text{RRR}=\ensuremath{\rho}(300\phantom{\rule{0.28em}{0ex}}\text{K})/\ensuremath{\rho}({T}_{c})=4.5$], and annealed (${T}_{c}\ensuremath{\approx}35$ K, $\tex…
Flip and hop before you're caught! The proton dynamics of solid 12-tungstophosphoric acid (TPA) is probed by solid-state (2)H NMR in a temperature range from 293-503 K. Protons of TPA are shown to be involved in two types of molecular motion (see picture): the anisotropic local two-site flipping between the two possib…
The mechanism of stress corrosion cracking (SCC) of carbon steel in fuel-grade ethanol was investigated. Repeated potentiodynamic polarization measurements were made during slow strain rate (SSR) tests. Current difference curves were determined from measurements made in the plastic and elastic regions. Peaks in the cu…
Abstract The synthesis of polystyrene (PS) brushes on fully deuterated PS nanoparticles by surface‐initiated nitroxide‐mediated radical polymerization (SI‐NMRP) is reported. Due to the high demand of deuterated monomers, an efficient deuteration procedure of suitable and readily available precursors is developed. SI‐N…
Corrosion behavior of Ag in atmospheres containing humidity and ozone (O3), with sodium chloride (NaCl) surface contamination and ultraviolet (UV) illumination, has attracted strong interest recently because of the failure of ASTM B117 testing for Ag. This paper further investigates the effects of these parameters on…
The corrosion behavior of electrolytic copper (>99.5% purity [UNS C11000]), carbon steel (AISI/SAE 1016 [(UNS G10160]), and Type 304 (UNS S30400) stainless steel in neutral tap water was examined by potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) using a rotating cylinder electrode…
