The determination of the solubility parameter of organic compounds has been of much significance in the chemical industry. In this study, we propose a predictive method based on the combination of the Group Contribution strategy with the Artificial Neural Network to calculate/estimate the solubility parameter values o…
Electrochemical properties of cyanide-bridged metal squares, [Ru(4)](4+) and [Rh(2)-Ru(2)](6+), clearly demonstrate the role of the nearest (NN) metal moiety in mediating the next-nearest neighbor (NNN) metal-to-metal electronic coupling. The differences in electrochemical potentials for successive oxidations of equiv…
The preparation and characterization of a mixed-valence π-cation radical derivative of an iron(III) oxochlorinato complex is reported. The new complex has been synthesized by the one-electron oxidation of a pair of [Fe(oxoOEC)(Cl)] molecules to form the dimeric cation [Fe(oxoOEC)(Cl)]₂⁺. The cation has been characteri…
A greige (non-bleached) cotton lint was used to fabricate non-woven fabrics on a Fleissner MiniJet, using different water pressures for the fiber entanglements. The greige cotton and its hydroentangled non-woven fabrics were primarily tested for their hexane extracts (waxes) and water-soluble (sugars) contents using t…
The crystal structure of the low-temperature form of synthetic naumannite [disilver(I) selenide], Ag(2)Se, has been reinvestigated based on single-crystal data. In comparison with previous powder diffraction studies, anisotropic displacement parameters are additionally reported. The structure is composed of Se layers…
Green composites made from natural fibers, and biopolymers offer a potential alternative to the petroleum-based materials, that are currently being used in many nonstructural applications. In spite of being biodegradable and eco friendly, range of applications is limited due to poor mechanical properties. Hence an att…
We present dislocation dynamics (DD) simulations of shear loops in a highly anisotropic linear elastic crystal. The equilibrium shapes of the loops are determined for the four principal slip systems of the body-centered-cubic lattice, using empirical elastic constants for α-Fe, for a range of temperatures over which i…
We propose a new method of creating light-emitting point defects, or G-centers, by modifying a silicon surface with hexamethyldisilazane followed by laser annealing of the surface region. This laser annealing process has two advantages: creation of highly dense G-centers by incorporating carbon atoms into the silicon…
We present a first-principles investigation of the structures and the dynamical stability of the austenite and martensite phases of binary Ti${}_{3}$Nb alloys, used as a model system for the superelastic and superplastic gum-metal alloy. For the body-centered cubic high-temperature $\ensuremath{\beta}$ phase, structur…
We present an innovative wet-chemistry-assisted nanotube-substitution reaction approach for the highly efficient synthesis of boron- and nitrogen-codoped single-walled carbon nanotubes (B(x)C(y)N(z)-SWNTs) in bulk quantities. The as-synthesized ternary system B(x)C(y)N(z)-SWNTs are of high purity and quality and have…
Hybrid inorganic–organic colloidal nanoparticles can be designed to achieve specific and complementary optoelectronic properties different from their sole organic and inorganic counterparts. The efficient coupling between organic and inorganic moieties facilitates optimization of these optoelectronic properties as sin…
Oxidative cyclization of a doubly N-confused bilane afforded a N-confused N,C-linked corrole (N-confused norrole), which was readily oxidized to form a C-fused N,C-linked corrole (C-fused norrole).
Water exchange on a molecular, purely inorganic cobalt-based water oxidation catalyst, [Co(4)(II)(H(2)O)(2)(α-P(1)W(9)O(34))(2)](10-) (1), in the catalytically relevant pH region (pH 6-10) is studied using (17)O-NMR spectroscopy and ultrahigh-resolution electrospray ionization mass spectrometry. The results are compar…
This feature article covers the fundamental chemistry and applications of photo-induced living surface grafting polymerization. The mechanism of activation of inert alkyl C–H bonds of polymer substrates, the structures of the active free radical and reversible dormant species, the modes of the grafting chain growth (i…
The multi-layer metal/polymer/metal thin-film structure allows charge conduction but limits thermal conduction. The charge conduction is supported by Ohmic interfacial charge transfer and doped bulk transport. The thermal conduction is limited by polymer low thermal conductivity, acoustic mismatch, interfacial phonon…
Abstract Tip‐enhanced Raman scattering (TERS) spectroscopy is a promising technique for nanoscale chemical analysis. However, there are several challenges preventing widespread application of this technology, including reproducible fabrication of efficient TERS probes. These problems reflect a lack of clear understand…
A novel method is presented which is suitable for assessing in vivo the link between the physicochemical properties of engineered nanomaterials (ENM) and their biological outcomes. The ability of the technique to generate a variety of industry-relevant, property-controlled ENM exposure atmospheres for inhalation studi…
Aqueous solutions of ferrous and ferric iron (Fe(2+/3+)) and of the iron-hexacyano complexes [Fe(CN)(6)](4-/3-) are studied by photoelectron spectroscopy using a liquid microjet in conjunction with synchrotron soft X-rays for ionization. For Fe(2+)(aq) we observe two well-resolved peaks at 7.09 and 9.16 eV electron bi…
Historical data have been critically compiled and analyzed for investigating the quantity of nepheline ( NaAlSiO 4 ) precipitated as a function of composition in simulated nuclear waste glasses. To understand compositional effects two primary methods were used: (1) investigating the Al 2 O 3 – SiO 2 – Na 2 O ternary w…
An iron-loss model for laminated ferromagnetic cores of electrical machines is presented and applied to estimate the core losses of an induction machine with finite-element analysis. Skin effect in the cross section of the core lamination is modelled using a set of sinusoidal basis functions while locally considering…
