ABSTRACT Core/multishell CdSe/CdS/CdS/Cd0.75Zn0.25S/Cd0.5Zn0.5S/Cd0.25 Zn0.75S/ZnS/ZnS QDs/PMMA bulk nanocomposites were successfully synthesized. To achieve a homogeneous and stable dispersion in MMA monomers, QDs were first modified with amphiphilic polymer of poly(ethylene glycol)‐oleate (PEG‐oleate). Subsequently,…
In this paper, a novel hybrid longitudinal–torsional magnetostrictive ultrasonic transducer (HL–TMUT) is introduced. The transducer is composed of a magnetostrictive exponential horn and a stainless steel tail mass. In this transducer a spiral magnetic field made up of longitudinal and circumferential magnetic fields…
AIM: The aim of this work is to evaluate combining targeting strategy and convection-enhanced delivery in brain tumor models by imaging quantum dot-immunoliposome hybrid nanoparticles. MATERIALS & METHODS: An EGF receptor-targeted, quantum dot-immunoliposome hybrid nanoparticle (QD-IL) was synthesized. In vitro uptake…
To understand the influence of orthogonal conjugation pathways fused directly to π-conjugated polymer backbones, we synthesized and studied three series of thiophene-based model compounds containing benzene, naphthalene, and anthracene peri-substituted central cores as representative acenes. These models were function…
Abstract In order to simulate the contact situation of interconnect/contact layer/cathode in SOFC stacks, contact resistance and chemical compatibility of LaNi 0.6 Co 0.4 O 3–δ (LNC) as contact layer between Crofer22APU interconnect and La 0.6 Sr 0.4 FeO 3 (LSF) cathode was investigated at 800 °C in air for more than…
An orange-emitting phosphor, Eu(2+)-activated LiSr4(BO3)3, was synthesized using the conventional solid-state reaction. The photoluminescence excitation and emission spectra, and temperature dependence of the luminescence intensity of the phosphor were investigated. The results showed that LiSr4(BO3)3:Eu(2+) could be…
A new series of Schiff base calamitic liquid crystal; methyl 4-(4′-n-alkoxybenzylideneamino)benzoate (MABAB), H2n+1C n OC6H4C(H)=NC6H4COOCH3 (n = 6, 8, 10, 12, 14, 16) has been synthesised and characterised by elemental analyses, Fourier transform infrared spectroscopy (FT-IR), 1H and 13C Nuclear Magnetic Resonance (N…
Abstract Some undesired nanoparticles, such as malformed structures or incomplete core/shell Fe3O4-Au nanocomposites, might be formed when Fe3O4-Au core/shell nanocomposites are being synthesized. These impurities should be separated before any applications are performed. In this investigation, magnetic cores (Fe3O4)…
The thermal decomposition behavior of poly(ether imide) (PEI)/carbon fiber composites used in aeronautical field was studied using thermogravimetric analysis in an inert atmosphere, at several heating rates between 2 and 10°C min −1 . The activation energies ( E a ) were determined by Flynn–Wall–Ozawa (FWO) and Kissin…
Living plants growing on mine waste were assisted to accumulate gold to a concentration greater than 3500 mg kg –1 (0.35%) dry weight. Where Au was the only high-density metal present in the soil at high concentration, discrete biogenic nanoparticles of the metal were observed in preparations of shoot and leaf biomass…
Abstract In this report, we describe fabrication and electrochemical‐performance testing of tubular, anode‐supported fuel cells based on the protonic ceramic BaCe0.2Zr0.7Y0.1O3–δ (BCZY27). These devices are comprised of a 20‐μm‐thick BCZY27 electrolyte spray‐coated and co‐fired onto an extruded, tubular 9.8‐mm‐diamete…
Photothermal therapy is a therapy in which photon energy is converted into heat to kill cancer. The purpose of this study is to evaluate the in vivo efficacy of photothermal therapy, toxicity and hepatic and renal function of polyaniline nanoparticles (PANI-Np) in a tumor-bearing mice model. The in vivo efficacy of na…
Natural fiber reinforced composites have replaced the existing conventional materials due to its light weight and enhanced load-bearing capabilities. In the present work, the newly identified snake grass ( Sansevieria ehrenbergii) fiber-reinforced isophthalic polyester composites are prepared by simple hand lay-up met…
Lead-based quantum dots (QDs) can be tuned to emit in the transparent region of the biological tissue (700 to 1100 nm) which make them a potential candidate for optical bioimaging. However, to employ these QDs as biolabels they have to retain their luminescence and maintain their colloidal stability in water, physiolo…
We compare the morphology and optical response of plasmonic nanostructures produced by pulsed laser deposition, consisting of a 2D distribution of Ag nanoparticles exposed to air or buried under an amorphous Al 2 O 3 layer whose thickness is tuned in the 0.5 to 14 nm range. We observe that the covering process leads t…
Stable multilayer films have been fabricated on the basis of alternating layer-by-layer assembly of an azulene-based supra-amphiphile and a photoreactive polyanion. Moreover, one component of the supra-amphiphile, pyrene, can be removed from the multilayer films, generating functional surface-imprinted multilayer film…
Inelastic neutron scattering measurements demonstrate that the magnetic interactions in antiferromagnetic LaFeAsO are two dimensional. Spin-wave velocities within the Fe layer and the magnitude of the spin gap are similar to the $A$Fe${}_{2}$As${}_{2}$ based materials. However, the ratio of interlayer and intralayer e…
Alkoxysilyl derivatives of dibenzoylmethanatoboron difluoride (DBMBF2) are synthesized by the hydrosilylation reaction of the corresponding O-allyl derivatives of DBMBF2 with triethoxysilane. The photophysical properties of the synthesized O-allyl and alkoxysilyl derivatives are investigated. It is found that the abso…
Organoplatinum(IV) complexes, [PtBrMe 2 (CH 2 -4-C 6 H 4 -N═N-Ph)(NN)], containing trans -azobenzene functional groups, have been prepared by trans oxidative addition of BrCH 2 -4-C 6 H 4 -N═N-Ph to the corresponding platinum(II) complexes [PtMe 2 (NN)], with NN = 2,2′-bipyridine, 1,10-phenanthroline, 4,4′-bis(ethoxyc…
