Abstract In this study, it was found that images scanned by a non‐contact optical instrument for topographic characterisation based on the principle of chromatic aberration give sufficient information to know the exact location of soil release polymer (SRP) deposition over fabrics. Through the comparison of reflected…
Abstract A facile approach for synthesis of hyperbranched polycarbosilane from AB 2 monomer via UV‐activated hydrosilylation is presented in this communication. The polymerization process was monitored using real‐time FTIR spectroscopy and the resulting hyperbranched polycarbosilanes were characterized using 1 H‐NMR,…
Micro-structures that mimic the extracellular substratum promote cell growth and differentiation, while the cellular reaction to a nanostructure is poorly defined. To evaluate the cellular response to a nanoscaled surface, NIH 3T3 cells were grown on nanodot arrays with dot diameters ranging from 10 to 200 nm. The nan…
This study discusses the photoalignment effect in a liquid-crystal (LC) film that is doped with nanoparticles and azo-dye. The vertical alignment induced by nanoparticles of polyhedral oligomeric silsesquioxanes can be changed into homogeneous alignment by the absorption of photoexcited azo-dye. An electrically tunabl…
We report the incorporation of various inorganic nanoparticles (NPs) (PbS, LaOF, LaF(3), and TiO(2), each capped by oleic acid, and CdSe/ZnS core/shell QDs capped by trioctylphosphine oxide) into vesicles (d = 70-150 nm) formed by a sample of poly(styrene-b-acrylic acid) (PS(404)-b-PAA(62), where the subscripts refer…
Structural, magnetic, and magnetotransport behaviors of ${\text{Fe}}_{2}{\text{V}}_{1\ensuremath{-}x}{\text{Cr}}_{x}\text{Al}$ Heusler-type alloys have been investigated in the present work. From the detailed analysis of data it is observed that increasing Cr content promotes site disorder of Fe and Al, which in turn…
Abstract Reaction of a rigid conjugated clamp‐like multi‐pyridineligand N , N ′‐bis(pyridin‐3‐yl)‐2,6‐pyridinedicarboxamide (H 2 L) with CuSO 4 · 5H 2 O or Cu(OAc) 2 resulted in the formation of two high‐nuclearity, discrete molecular copper(II) complexes, namely [Cu 10 (H 2 L) 5 (SO 4 ) 8 (μ 3 ‐OH) 4 (H 2 O) 2 ] · 4C…
Abstract The effect of microstructure modifiers, Sn and Ag, on the corrosion rate of commercial Pb–Ca alloy in H 2 SO 4 electrolyte was investigated by the potentiodynamic polarization and by the weight loss corrosion rate measurement at the open circuit potential. The effect of microstructure modification of the Pb–C…
For the first time, single and dual mode novel left-handed coupled line couplers implemented on ferrite substrates are reported. Both of the proposed couplers demonstrate novel characteristics of coupler operation with properties of tunability and non-reciprocity, which have not been demonstrated before. The proposed…
The dispersion diagrams of surface plasmon polaritons have been calculated for rectangular gratings, with very narrow wires, of varying depths. For gratings with a moderate height a family of vertical-standing-wave resonances may be excited, which consist of surface plasmons, oscillating on either vertical surface, co…
Superconductivity and phase relationships were explored in the Na-Fe-As system. The PbFCl-type 111 phase is stable only within a Na stoichiometry range of 1.00 to $\ensuremath{\sim}0.85$, and exhibits bulk superconductivity within an even narrower range around 0.90 in ${\text{Na}}_{0.9}\text{FeAs}$. In particular, sto…
Abstract The purpose of this work is to evaluate a new tetra‐functional peroxide initiator and offer comparisons with a di‐functional peroxide commonly used in the production of controlled‐rheology polypropylene (CRPP) resins. CRPP resins have been produced by reactive processing in a batch mixer by using various equi…
An examination of the aqueous solution solubility and batch crystallization kinetics of l -isoleucine at the 250 mL scale size under a poly- and isothermal process condition is presented. Solubility data determined are consistent with the existence of two l -isoleucine polymorphic forms, in which both forms have diffe…
It is shown that an appropriate combination of thermal oxidation and high-pressure water vapor annealing for nanosilicon leads to efficient blue-band phosphorescence with a lifetime of several seconds. Based on spectroscopic analyses on both the temperature dependence of decay dynamics and the change in the peak wavel…
Using first-principles calculations, we report the adsorption of adenine dinucleoside on single-walled carbon nanotubes (CNTs) with various diameters and chiral angles. The calculations indicate that in addition to noncovalent $\ensuremath{\pi}\text{\ensuremath{-}}\ensuremath{\pi}$ interactions between the adenine bas…
Tissue engineering is currently being actively investigated to ascertain if it can offer an alternative to prosthetic aortic heart valves that may overcome the current limitations of prosthetic aortic heart valves while at the same time conferring the advantages of a living autologous structure, such as biocompatibili…
Soil testing is an important tool for estimating soil K availability and determining how much fertilizer must be applied to realize crop yield potential and minimize fertilizer costs. Our primary objectives were to correlate relative rice ( Oryza sativa L.) yield with Mehlich‐3 and 1 mol L −1 HNO 3 extractable K, defi…
Polyurethanes and polyurethane nanocomposites can be applied to control the release of drugs previously incorporated into these materials. In this study, dexamethasone acetate (ACT) was incorporated into biodegradable and biocompatible polyurethane and polyurethane containing montmorillonite nanoparticles. Fourier tra…
Abstract Kleine Anfänge : Metallnanopartikel‐CNT‐Nanohybride wurden aus Kohlenstoffnanoröhren (CNTs), die mit einer polymeren ionischen Flüssigkeit funktionalisiert waren, hergestellt. Die Pt‐ und PtRu‐Nanopartikel mit einer engen Größenverteilung (mittlerer Durchmesser: (1.3±0.4) nm für PtRu, (1.9±0.5) nm für Pt) sin…
Zinc oxide nanowire field-effect transistors (NW-FETs) were fabricated combining the dielectrophoresis (DEP) and the hot-pressing methods. DEP was used to position both ends of the nanowires on top of the source and the drain electrodes, respectively. Hot-pressing of nanowires on the electrodes was then employed to en…
