Barium Titanate BaTiO3 is known for both its electric and magnetic properties. The synthesis and characterization of iron doped barium titanate; BaTi1-xFexO3 (x= 0.005, 0.01, 0.015) was investigated with a view to understand its structural, magnetic and electrical properties. A finest possible sample of Iron doped mic…
In this study, we fabricated nitrogen-enriched multimodal porous carbons (NMPCs) from a self-assembled inclusion complex induced by the interaction between urea hydrates as host molecules and cellulose molecules as guest molecules for supercapacitors. The novel carbon material could be obtained on a gram-scale due to…
We present a large-area, highly aligned lamellar block copolymer self-assembly directed by graphoepitaxially aligned cylinder block copolymer self-assembly. Asymmetric block copolymer thin films were graphoepitaxially assembled within 1 μm wide parallel photoresist trenches to generate surface-parallel nanocylinder ar…
Magnetic polypropylene (PP) polymer nanocomposites (PNCs) were fabricated with the reinforcing core–shell Fe–Fe2O3 nanoparticles (NPs) synthesized by an in-situ thermal decomposition method. Maleic anhydride functionalized PP (M-PP) with two different molecular weights (Mn = 800, called LM-PP; Mn = 8000, called HM-PP)…
We consider dense systems consisting of ultrasoft, overlapping particles under shear and transport flow, by employing a multiscale simulational approach that combines multiparticle-collision dynamics for the solvent particles with standard molecular dynamics for the solute. We find that the nucleation rates of superco…
2-D NCS-bridged {3d-4d} molecule-based magnets, formed by reaction of [Mo(III)(NCS)(6)](3-) with either Ni(II) or Co(II) complexes, have been found to exhibit magnetic ordering with T(C) = 39 K for {Co(3)Mo(2)} while {Ni(3)Mo(2)} has a non-magnetic ground state as a result of exact compensation by the individual sub-l…
Herein we report a novel transparent organic-inorganic hybrid material exhibiting the emission characteristics of lanthanides by polymerization of liquid monomer MMA containing surface modified zeolite L, inside the channels of which luminescent lanthanide complexes are incorporated. The obtained materials were charac…
The Ba[Zn1/3(Nb1−xTax)2/3]O3 (BZNT, x = 0.0, 0.2, 0.4, 0.6, 0.8, 1.0) solid solutions were synthesized by conventional solid-state sintering technique. Vibration spectra (Raman spectroscopy) and x-ray diffraction (XRD) were employed to evaluate the correlation between crystal structures and vibration modes of these so…
In this study, we used a solution process, involving direct molecular exfoliation of graphite oxide (GO) stacked layers, to obtain individual graphene oxide platelets (GOPs) through amphiphilic hyperbranched polymers (HPs). The HPs, based on poly(amic acid) and polyimide with terminal amino functionalities, were obtai…
Dendrimers are polymers with unique properties that make them promising in a variety of applications such as potential drug and gene delivery systems. Polyamidoamine (PAMAM) dendrimers, in particular, have been widely investigated since they enter rapidly into cells. The entry mechanism, however, is still not yet full…
One-dimensional La(9.33)(SiO(4))(6)O(2): Ln(3+) (Ln = Ce, Eu, Tb) microfibers were fabricated by a simple and cost-effective electrospinning method. X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), high-resolution tran…
Cholesterol appended pyridinium ureas 1 and 2 have been designed and synthesized. The unsymmetrical urea-based chemosensor 1 fluorimetrically distinguishes F(-) from the other anions examined in both CH(3)CN and DMSO with appreciable binding constant values. The pyridinium - based symmetrical compound 2 acts as a low…
The facile synthetic approach to ruthenium oxide nanoparticles using double hydrophilic block copolymers (DHBCs) and their application toward the supercapacitor are presented. Nanostructured hydrous ruthenium oxide (RuO2) nanoparticles are synthesized using a double hydrophilic block copolymer of poly(ethylene oxide)-…
Reaction of the nitronyl nitroxide radical NIT-3Brthien with Ln(hfac)3 affords two one-dimensional lanthanide–nitronyl nitroxide compounds [Ln(hfac)3(NIT-3Brthien)] (Ln = Gd(III) 1, Tb(III) 2; NIT-3Brthien = 2-(3′-bromo-2′-thienyl)-4,4,5,5-tetramethyl-imidazoline-1-oxyl-3-oxide). Single crystal X-ray crystallographic…
A novel hybrid organic/inorganic clay prepared by intercalation of a luminescent polyhedral oligomeric silsesquioxane (POSS) in a nanosized synthetic saponite clay was synthesized and characterized by a multidisciplinary approach including XRD, HRTEM, TGA and UV-Vis and photoluminescence spectroscopies. The luminescen…
Controlled synthesis of β-NaLuF4 with uniform morphology, dimension and considerable monodispersity was designed via a gentle solvothermal process by using ethylenediamine (EDA) and ethylene glycol (EG) as the mixed solvent and NaNO3 as a mineralizer. X-ray diffraction (XRD), field scanning electron microscopy (FESEM)…
The use of self-assembling monolayers (SAM) of long chain carboxylic acids has a potential for designing specific interface architectures in degradable implants technology.
