We demonstrate a simple interferometric probe to detect nanoscale dynamics of sessile fluid drops on arbitrary rough or flexible substrates. The technique relies on producing high-contrast Newton-ring like dynamical fringes by interference between a weak Fresnel reflection from the air-fluid interface of the drop and…
BACKGROUND: Egyptian goose breast meat has been found to be very tough compared to the meat of other well-known fowl species. In attempting to clarify the toughness of the meat, the physical and biochemical changes during post-mortem conditioning (14 days) was investigated. RESULTS: Although there was increased cathep…
Purpose: To formulate and evaluate floating microparticulate oral diltiazem delivery system for possible delivery to the heart.Method: Floating microspheres were prepared using cellulose acetate and Eudragit RS100 polymers by emulsion solvent evaporation technique. The dried floating microspheres were evaluated for mi…
Defects in drivetrains of wind turbines are typically very costly due to the difficulty in accessing the defective components for repair and maintenance. Electrical discharge has been identified as one of the key root causes to defects in wind drivetrains. Improving the reliability of key wind turbine components has b…
Films of poly(vinyl alcohol) / cadmium sulphide (PVA/CdS) nanocomposite containing various concentrations of Cd 2+ ions were prepared using gamma radiation at different doses from 50 up to 200 kGy. The UV/VIS spectra revealed that the CdS/PVA nanocomposites showed blue shift for the absorption peak as compared with bu…
Here we investigate the effects of absorbing media on plasmon-enhanced near-field optical energy deposition. We find that increasing absorption by the medium results in increased particle scattering at the expense of particle absorption, and that much of this increased particle scattering is absorbed by the medium clo…
A homologous series of the phthalocyanine-fullerene dyads, (C n S) 6 PcCu-C m -C 60 (4a~g) [(n, m) = (14, 8) (a); (14, 10) (b); (14, 12) (c); (16, 8) (d); (16, 10) (e); (16, 12) (f); (18, 10) (g)], have been synthesized with changing both the chain length of the peripheral alkylthio group (n) and the spacer length (m)…
Objective: Application of nanotechnology in drug delivery system has released leading new areas of research in sustained release of drugs. The objective of the present study is development and optimization of polymeric nanoparticles of Nateglinide (NTG). Methods: Nateglinide loaded ethyl cellulose (EC) nanoparticles w…
Abstract Two hexagonal series of lanthanoid(III) oxide fluoride selenides with similar structure types can be obtained by the reaction of the components M F 3 , M 2 O 3 , M , and Se in sealed niobium tubes at 850 °C using CsI as fluxing agent. The compounds with the lighter and larger representatives ( M = La – Nd) oc…
Abstract While water‐compatible Lewis acids have great potential as accessible and environmentally benign catalysts for various organic transformations, efficient immobilization of such Lewis acids while keeping high activity and without leaching of metals even under aqueous conditions is a challenging task. Self‐asse…
In this article, plasma-sprayed coatings of borosilicate glass microspheres (BGM) premixed with TiO2 particles in different proportions are deposited at various input power levels of the plasma torch. Erosion wear characteristics of these coatings are investigated following a plan of experiments based on the Taguchi t…
Abstract The microstructure of as-cast and as-HIPed (hot isostatic pressed) K403 superalloy was investigated using a scanning electron microscopy (SEM), as component analysis was conducted by energy dispersive x-ray spectrometer (EDS). It was found that the microstructure of the alloy was improved significantly throug…
Abstract An easily feasible method to measure surface phonons of specific crystalline solids is described. Special experimental conditions allow confining Raman scattering to the surface region of crystals, while the contribution of bulk scattering to the spectra is largely excluded. Such conditions exist for example…
This paper presents an attempt at the evaluation of the non-linear, multi variable dependency between the main (tangential) force, FC, and the machining parameters and properties of Pedunculate oak (Quercus robur) during, straight edge, peripheral milling. Tangential force, FC, was found to be influenced by density, D…
We use series expansions to investigate the zero-temperature phase diagram of the Heisenberg-Kitaev model. Our work confirms the presence of four distinct magnetically ordered phases, identified in recent work, and provides accurate values of the ground state energy and order parameter throughout. We call into questio…
Abstract Integrated layered‐spinel composite materials are synthesized through the facile decomposition of Li4Mn5O12‐based spinel materials at 900 °C. The intergrowth of spinel Li1+zMn2−zO4 (0<z<0.33) and Li‐rich layered Li2MnO3 components is examined by using X‐ray diffraction and high‐resolution transmission electro…
A facile, rapid and green method based on potentiostatic electrodeposition is developed to synthesize a novel H3PMo12O40-Pt/reduced graphene oxide (denoted as PMo12-Pt/rGO) composite. The as-prepared PMo12-Pt/rGO is characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and X-ray photoelectron sp…

Self-assembled nan…
Corneal keratocyte apoptosis triggered by cornel debridement is one mechanism of corneal disorders. In this study, the feasibility of cyclo-(d-Trp-Tyr) peptide nanotubes (PNTs) as carriers of caspase 3 silence shRNA delivery was assessed. A model of epithelial injury by epithelial debridement was applied to investigat…
The mostly advanced polarographic mode of measurement, square wave (SW), was applied for studying reduction of for 2,2-Dimethyl-1,3-dioxan-4,6-dione (Meldrum acid) and its 5-phenyl-azo substituent in 40% v/v ethanolic universal buffer (pH~ 2–12). At more negative potentials, a 2e pH-dependent wave (dEp/dpH = 31 mv) wa…
