Tobacco mosaic virus (TMV) was electrospun with polyvinyl alcohol (PVA) into continuous TMV–PVA composite nanofibers to form a biodegradable nonwoven fibrous mat as an extracellular matrix (ECM) mimetic. Morphological characterizations by electron microscopy showed that the addition of varying amounts of TMV resulted…
Impregnation of [(AliBu(3))(Et(2)O)] on partially dehydroxylated SBA-15 affords a mesoporous material bearing the well-defined single site surface aluminium species [(≡SiO)(2)Al(iBu)(Et(2)O)].
Trinuclear complexes of Mn(II), Fe(II), Co(II), Ni(II), Cu(II), and Zn(II) were synthesized using a ligand architecture based upon a 1,3,5-triarylbenzene core decorated with six pyridines and three alkoxide moieties. Characterization via X-ray diffraction, NMR, and magnetism studies is discussed.
A series of experiments were performed to systematically analyze the effect of nanoparticle (NP) size on the catalytic behavior of enzyme-NP conjugates, and a shielding model based on diffusion-collision theory was developed to explain the correlation between the size effects and the kinetic responses.
Metal jet emission and weld interface formation in impact welding were investigated for similar- and dissimilar-metal lap joints. Numerical simulation of oblique collision between metal plates was performed using smoothed particle hydrodynamics (SPH) method for various plate thicknesses, collision velocities, and coll…
Proton-blocking La 0.7 Sr 0.3 FeO 3− δ –Ce 0.8 Sm 0.2 O 2− δ (LSF–SDC) and proton-conducting La 0.7 Sr 0.3 FeO 3− δ –BaZr 0.1 Ce 0.7 Y 0.2 O 3− δ (LSF–BZCY) composites were evaluated as cathodes for BaZr 0.1 Ce 0.7 Y 0.2 O 3− δ (BZCY)-based proton-conducting solid oxide fuel cell (H-SOFC) comparatively. The XRD result…
This work reports the preparation of a novel hybrid nanocatalyst through the immobilization of oxidovanadiumIV acetylacetonate ([VO(acac)2]) onto silica nanoparticles functionalized with 3-aminopropyltriethoxysilane (APTES) and its catalytic application in the allylic epoxidation of geraniol. All the nanomaterials wer…
Two octamolybdate hybrid materials, namely, [Co2(HL)2(L)(H2Mo8O28)] (1) and [Co(L)2.5(Mo8O26)0.5]·H2O (2) (L = 1,1′-(1,4-butanediyl)bis(imidazole)) have been successfully synthesized at different pH values under hydrothermal conditions. Compound 1 displays a 3D (65·8) CdSO4-type framework. The most peculiar feature of…
The electrochemical characteristics for the electrical double layer capacitors (EDLCs) based on the microporous carbon cloth (MPCC) electrode and 1-ethyl-3-methyl imidazolium tetrafluoroborate or 1-ethyl-3-methyl imidazolium tetracyanoborate as an electrolyte have been studied using the cyclic voltammetry and impedanc…
A priori and a posteriori error estimates are derived for the numerical approximation of scalar and complex valued phase field models. Particular attention is devoted to the dependence of the estimates on a small parameter and to the validity of the estimates in the presence of topological changes in the solution that…
Hollow polymeric microcapsules with specific responses to mannose, fructose, glucose and its corresponding polysaccharide, dextran, at the physiological pH range were fabricated from Concanavalin A, a plant lectin, and glycogen, a polysaccharide, based on the lectin–carbohydrate interaction in a layer-by-layer fashion…
Varying the solution growth conditions of cooperative binary ionic solids composed of anionic and cationic metalloporphyrins produces a series of families of self-assembled structures that efficiently and durably photosensitize the evolution of hydrogen.
One route has been employed to prepare dendritic-linear block copolymer modified superparamagnetic iron oxide nanoparticles (SPIONs), which consist of a Fe3O4 magnetic nanoparticle core and a dendritic-linear block copolymer, the focal point polyamidoamine-type dendron-b-poly(2-dimethylaminoethyl methacrylate)-b-poly(…
An amphiphilic low-molecular-weight hydrogelator 1 was synthesized. A tris-glycine-SDS solution gel of 1 was applied for electrophoresis to separate proteins. Centrifugation of a mixture of protein and a hydrogel of 1 enabled the recovery of protein. Various combinations of proteins were applied for supramolecular gel…
ZnO nanorods were fabricated by a template-free gel pyrrolysis method based on polyvinyl alcohol (PVA) polymeric network. In the present method, zinc salt precursor is trapped in the homogenized gel network to control the mechanism and kinetics of zinc salt calcinations process. By controlling the gel structure and ge…
A self-assembled supramolecular triad as a model to mimic the light-induced events of the photosynthetic antenna-reaction center, that is, ultrafast excitation transfer followed by electron transfer ultimately generating a long-lived charge-separated state, has been accomplished. Boron dipyrrin (BDP), zinc porphyrin (…
Following the enhancing demand for packaged raw food products with extended shelf-life, intensive efforts have been made developing active packaging materials with incorporated antimicrobials. With regard to technical problems in the production of antimicrobial films containing sorbic acid, the aim of this study was t…
The effect of heat treatment on the microstructure and the mechanical properties of a 10%Cr steel with 0.008% boron was examined. The microstructure and the mechanical properties of this steel subjected to the normalizing were studied after tempering under different conditions. The layers of retained austenite are loc…
Monodisperse hollow magnetite microspheres were successfully synthesized by an one-step process through a tem-plate-free hydrothermal approach employing simultaneously a mixture of FeCl3.6H2O and ferrocene as precursor and a propylene glycol-isopropanol mixture as solvent. The morphologies and properties of the magnet…
A facile microwave-assisted hydrothermal method was developed to prepare oxynitride-based (Sr1−x−yCexTby)Si2O2−δN2+μ phosphors. The microwave-assisted hydrothermal process led to lower synthesis temperatures and shortened heating duration. The obtained powders exhibited a narrow size distribution. The Rietveld refinem…
