Solution-processable metal–halide perovskites recently opened a new route toward low-cost manufacture of photovoltaic cells. Converting sunlight into electrical energy depends on several factors among which a broad absorption across the solar spectrum and attractive charge transport properties are of primary importanc…
We consider Cahn–Hilliard equations with external forcing terms. Energy decreasing and mass conservation might not hold. We show that level surfaces of the solutions of such generalized Cahn–Hilliard equations tend to the solutions of a moving boundary problem under the assumption that classical solution of the latter…
A chemiresistor vapor sensor based on electron transport through an ensemble of ligand-stabilized gold nanoclusters is made exceptionally sensitive and selective by terminal carboxylic acid functionalization of the alkanethiol ligand. The directionality of the response (conductance increase or decrease) is strongly de…
Foam drainage regimes are significantly associated with the nature of the hydrodynamic resistance in foam structure. A multi‐point electrical resistance measurement technique has been applied for characterization of the drainage regimes and quantifying stability within standing foams. The capacity of the technique was…
SnO2-Ag composite nanomaterials of mass ratio 1:4, 2:3, 3:2 and 4:1 were fabricated and tested for toxicity to E. coli using the pour-plate technique. The said nanomaterials were mixed with laminating fluid and then coated on glass slides. The intensity of UVA transmitted through the coated glass slides was measured.…
In this work, rapidly grown KH2PO4 (KDP) crystals extracted from the prismatic and the pyramidal growth sectors of crystal boules were analyzed using photoluminescence measurements. From the spectra, we deduced a robust criterion to discriminate between both growth sectors in an unknown KDP plate. Moreover, spatially…
The dependence of the electrical properties on the structural variation and annealing conditions are explored for the turbostratically disordered misfit layered compounds [(PbSe)1.00]m(MoSe2)n where m and n range between 1 and 5 layers. The thickness of the PbSe and MoSe2 layers both appear to have a significant impac…
The self-assembly of a series of nonionic amphiphilic cruciforms based on the 1,2,4,5-tetrakis(phenylethynyl)benzene (TPEB) skeleton, in which the peripheral substituents have been modified to modulate the morphology of the supramolecular structures, is reported. The presence of linear paraffinic and hydrophilic chain…
We investigated herein the reactions of (Me3tacn)FeCln (1a: n = 3, 1b: n = 2) with common aluminum hydride reagents and a bulky dihydridoaluminate {Li(ether)2}{Al(OC6H3-2,6-(t)Bu2)}(μ-H)2, which yielded the diamagnetic hydrido complexes 2-4 containing Fe(II) and Al(III). In particular, the use of divalent 1b afforded…
Site-selective and fluorescence line narrowing (FLN) laser spectroscopy was used to study the structure of Eu3+-doped Gd2O3-based material embedded in the mesopores of submicron-sized monodisperse spherical amorphous SiO2 particles that are of interest for biomedical applications. The phase composition of the material…
Process parameters affecting the photocatalytic performance of thin films of titanium dioxide were investigated. Nanorods of titanium dioxide were grown using the technique of oblique angle deposition to create porous films of high surface area. The surface area of the films was measured as a function of deposition an…
ABSTRACT Double‐layer films, prepared by casting films of xanthan gum (XG), and subsequently poly(vinyl acetate) (PVAc) onto the former, are reported. The resulting XG/PVAc films provide high protection as coatings to a bleaching agent, 6‐(phthalimido)peroxyhexanoic acid, in liquid detergents, due to the combined role…
Previous researchers established a set of reference cottons with known fiber maturity and linear density (fineness) values based on the analysis of a large number of individual transverse fiber cross-sections viewed under the optical microscope. Part 1 identified that the limited optical resolution of the captured ima…
In this article, ramie fiber reinforced phenolic (RFRP) plates were prepared with compression molding process, and the plates were subjected to 98% humidity environment and alternating temperatures (from 25°C to 55°C in 24 h for a cycle) for 4 weeks. The resulted moisture absorption and the variation of the mechanical…
Abstract Step sites over terrace sites have been suggested to be the active sites in many catalytic reactions particularly bond breaking of diatomic molecules. Aiming to provide insight into the role of step sites in multiatomic molecules bond breaking reactions and their dependence on catalysts, we present herein a s…
A series of carbonate intercalated Zn-Al layered double hydroxides (Zn-Al LDH) and their calcined products (Zn-Al CLDH) with various Zn/Al atomic ratios were synthesized and characterized. Samples were evaluated for performance in bromate removal. The main objective of this research is to evaluate and define the optim…
In previous studies, we reported the first observation of the Au-S bond breakage induced mechanically by the swelling of the surface-tethered weak polyelectrolyte brushes in phosphate buffered saline (PBS), a phenomenon with broad applications in the fields of biosensors and functional surfaces. In this study, three f…
A detailed biomechanical model of the human face driven by a network of muscles is a useful tool in relating the muscle activities to facial deformations. However, lengthy computational times often hinder its applications in practical settings. The objective of this study is to replace precise but computationally dema…
Abstract A series of lanthanoid and iodine containing compounds of formulae [Ln(IPhacac)3(dmf)2], [K(dmf)2{Ln(IPhacac)4}]n and [Ln5(OH)5(IPhacac)10] {(IPhacac) = bis(para‐iododibenzoyl)methanide} have been prepared and structurally characterised. X‐ray crystallography establishes that the compounds exist as monomers […
A major challenge in the synthesis of porous metal oxides is the control of pore size and/or wall thickness that may affect the performance of these materials. Herein, nanoporous β-MnO₂ samples were prepared using different hard templates, e.g., ordered mesoporous silica SBA-15 and KIT-6, disordered mesoporous silica,…
