Aminophenyl boronic acids can form reversible covalent ester interactions with cis-diol-containing molecules, serving as a selective tool for binding glycoproteins as antibody molecules that possess oligosaccharides in both the Fv and Fc regions. In this study, amino phenyl boronic acid (APBA) magnetic particles (MPs)…
Very fine alumina nanoparticles were loaded in novolac type phenolic resin (PF) using solution mixing method. The concentration of nanoalumina in PF was varied between 2.5 to 20 wt%. All the compounds were compression molded and then subjected to scanning electron microscopy (SEM), tensile, flexural, and dynamic mecha…
Positron annihilation spectroscopy (PAS) comprising of the measurements of positron lifetime and coincidence Doppler broadening spectra has been carried out to understand and monitor the evolution of the vacancy-type defects arising from the ionic deficiencies at lattice points of the multiferroic perovskite bismuth f…
The influence of hot pressing conditions on mechanical properties of nickel aluminide/alumina composite has been investigated in the present paper. In particular, effect of the process parameters, viz. compacting pressure, sintering temperature and sintering time on the evolution of density, elastic constants and tens…
We present simultaneous measurements of acoustic emission and magnetic Barkhausen noise during the thermally induced martensitic transition in a Ni-Mn-Ga single crystal. The range where structural acoustic emission avalanches are detected extends for more than 50 K for both cooling and heating ramps, with a hysteresis…
Securing fragile nanostructures against external impact is indispensable for offering sufficiently long lifetime in service to nanoengineering products, especially when coming in contact with other substances. Indeed, this problem still remains a challenging task, which may be resolved with the help of smart materials…
Without a proper waste management, the organic wastes such as cassava peels could result in increased amount of solid waste dump into landfill. This study aims to use non-wood organic wastes as pulp for paper making industries; promoting the concept of ‘from waste to wealth and recyclable material’. The objective of t…
The reaction of the digold(I) complex [Au2(dppm)(D-pen)2](2-) ([1](2-); dppm = bis(diphenylphosphino)methane and D-pen = D-penicillaminate) with Zn(2+) in a 1:1 ratio gave the heterometallic Au(I)2Zn(II) trinuclear complex [Au2Zn(dppm)(D-pen)2] ([3]), in which the Zn(2+) ion is coordinated by [1](2-) in an N2O2S2 octa…
<div class="section abstract"><div class="htmlview paragraph">A simple 1-dimensional filter model, with symmetric and asymmetric channels, has been developed to investigate the fundamental behavior and performance of ceramic partial diesel particulate filters (PFs). The governing equations of mass and mome…
OBJECTIVE: Characterize the flux of platelet-endothelial cell adhesion molecule (PECAM-1) antibody-coated superparamagnetic iron oxide nanoparticles (IONPs) across the blood-brain barrier (BBB) and its biodistribution in vitro and in vivo. METHODS: Anti-PECAM-1 IONPs and IgG IONPs were prepared and characterized in ho…
A one-pot solution synthesis of monodisperse AgGaS2 nanocrystals with uniform pyramid-like shape is realized for the first time, in which an interesting phase and shape evolution from monodisperse Ag2S nanospheres to pure AgGaS2 nano-pyramids through an intermediate stage of Ag2S-AgGaS2 heterostructures, is revealed.…
We report a facile fabrication of a host-metal-guest coordination-bonding system in a mesostructured Fe3O4/chitosan nanoparticle that can act as a pH-responsive drug-delivery system. The mesostructured Fe3O4/chitosan was synthesized by a solvothermal approach with iron(III) chloride hexahydrate as a precursor, ethylen…
A family of Ce0.95−xGdxEu0.05(OH)CO3·H2O monodispersed spherical particles of ca. 200 nm with 0 ≤ x ≤ 0.95 was obtained by the urea homogeneous alkalinization method. These precursors were decomposed at 1273 K under an air atmosphere, resulting in ternary spheroidal phosphors obeying the general formula Ce0.95−xGdxEu0…
Abstract BACKGROUND Sn‐doped metal oxides have attracted considerable attention due to their potential applications in environmental remediation by degrading organic pollutants to less harmful byproducts and hydrogen generation from water splitting. Divalent tin was doped into defect pyrochlore K 0 . 51 Sb 2 . 67 O 6…
We demonstrate the relation between critical temperature $T_{\rm c}$ and transport properties in $R$FeP$_{1-x}$As$_x$O$_{0.9}$F$_{0.1}$ ($R$=La, Pr and Nd). $T_{\rm c}$ and resistivity power-law exponent $n$ form a universal line on the $T_{\rm c}$ vs. $n$ plane for all the $R$-systems with $x$$<0.6\sim$0.8, indicatin…
The present article depicts the influence of independent control factors such as microstructural variation, normal load, sliding velocity, and test duration on the dry sliding wear behavior of titanium alloy at room temperature using a statistical approach. Different heat treatments were carried out in a controlled ma…
Abstract Hydrolysis of bismuth(III) nitrate in the presence of sodium benzoate (NaOBz) in dimethyl sulfoxide (DMSO) gave the bismuth oxido cluster [{Bi 38 O 45 (NO 3 ) 20 (OBz) 4 (DMSO) 24 } · 4DMSO][{Bi 38 O 45 (NO 3 ) 24 (DMSO) 26 } · 4DMSO] ( 1 ), which crystallizes in the monoclinic space group P 2 1 / c with cell…
Abstract Durch Ionenaustausch wurde MoO 3 hochdispers (0.2–2.5 Mo‐Atome nm −2 ) auf die Oberfläche von mesoporösem SiO 2 (SBA‐15) aufgetragen. Röntgenabsorption, UV/Vis‐, Raman‐ und IR‐Spektroskopie zeigten, dass zweifach verankerte tetraedrische MoO 4 ‐Dioxo‐Einheiten unabhängig von der Beladung dominieren. Eine verb…
Grain refinement of GaAs was achieved by application of severe plastic deformation through high-pressure torsion (HPT). Ultrafine-grained structures including nanograins were produced by the HPT processing under 24 GPa. An intense photoluminescence (PL) peak in the near infrared corresponding to the band gap of GaAs d…
In lattice systems, the effects of optical phonons on heat transport are usually neglected due to their relatively small group velocities compared with acoustic phonons, or even assumed to be negative because introducing optical phonons may simultaneously reduce the group velocities of acoustic phonons. In order to we…
