Dielectric permittivity measurements were performed on water solutions of propylene glycol (PG) and propylene glycol monomethyl ether (PGME) confined in 21 Å pores of the silica matrix MCM-41 C10 in wide frequency (10(-2)-10(6) Hz) and temperature (130-250 K) ranges. The aim was to elucidate how the formation of large…
Photo-responsive self-assemblies based on bio-inspired bolaamphiphiles with oligo (ethylene oxide) hydrophilic outer segments and a hydrophobic inner segment with thymine were investigated. The morphology of the self-assemblies transformed from ribbon-like structures to spherical structures in water by UV irradiation…
We propose a novel approach to obtain conducting polymer nanoparticles with high electrochemical activity and a narrow size distribution. The method - templateless and seedless - uses polyacrylate microspheres to deliver the monomer for the polymerization reaction. Thus the obtained nanostructures have an active - unb…
The water soluble tris-aqua complex [Gd(dhqN-SO3)(H2O)3](3-) based on a hexadentate hydroxyquinoline ligand shows high thermodynamic stability and high relaxivity (12.54 mM(-1) s(-1) at 1.2 T). Its non-covalent confinement in 25 nm silica nanoparticles prevents transmetallation and endogenous anion binding and leads t…
Multicomponent particles have emerged in recent years as new compartmentalized colloids with two sides of different chemistry or polarity that have opened up a wide field of unique applications in medicine, physics and chemistry.
The TSV filling using the dialyl-amine and the Br − and Cl − halogen ions to a copper electrodeposition bath is reported. The TSV bottom acceleration and TSV outside inhibition have been measured by an electrochemical method using the rotating disk electrode and numerical computation of the fluid dynamics. A perfect T…
Single walled carbon nanotubes as free-radical scavengers and novel drug carriers are important in the drug delivery systems because of their high selectivity to target for cancer cells. Quercetin, one of Flavonoids derivatives, has effective chemopreventive and anticancer properties. This study was done to investigat…
This paper describes a robust and efficient numerical scheme for solving the system of six coupled partial differential equations which arises when using $Q$-tensor theory to model the behavior of a nematic liquid crystal cell under the influence of an applied electric field. The key novel feature is the use of a full…
In this study, <italic>via</italic> first-principles calculations, we predict a stable planar Y <sub>2</sub> O <sub>3</sub> (111) monolayer with a direct band gap of 3.96 eV. This high- <italic>κ</italic> dielectric monolayer can be further stabilized by a graphene substrate.
Novel multilayer films of graphene oxide/copper phthalocyanine (GO/CuPc) were fabricated by self-assembling in the orientational ordered liquid crystalline state and immobilizing of the ordered structure upon casting and drying.
The dilution controlled aggregation enhanced emission of spherically aggregated form of a triazole based probe dies down upon detecting iodide over other inorganic anions. The sensing is realised as a dynamic quenching mechanism dominated event. Being highly selective for iodide, the probe finds application in the det…
Amorphous Ge (a-Ge), crystalline Ge (c-Ge), and amorphous Si (a-Si) thin films were deposited on a Ge substrate at different temperatures by magnetron sputtering.
Variation of PL intensity with heat treatment duration of RE-doped (CBS-2) and nanometal/RE-doped (CBS-3) chloroborosilicate glasses.
New mesogenic compounds exhibiting unique, so called orthoconic, behavior at the synclinic smectic SmC* phase have been obtained.
The luminescence properties of Tb(3+) in CaWO4 crystals are investigated under a hydrostatic pressure of up to 200 kbar, i.e. across scheelite-to-fergusonite phase transition. It is shown that the typical blue ((5)D3) and green ((5)D4) emissions in this material are progressively quenched at room temperature as pressu…
Flexible and solid-state supercapacitors are made using compressed graphene foams as electrodes and highly conductive carbon nanotube (CNT) films as current collectors.
Surfactants or polymers are usually used for the liquid processing of carbon nanotubes for their structure separation. However, they are difficult to remove after separation, affecting the intrinsic properties and applications of the separated species. Here, we report an ethanol-assisted gel chromatography for the chi…
In this paper, we evaluate the transferability of the coarse-grained (CG) force field (FF) of trans-1,4-polybutadiene which was built via a combined structure-based and thermodynamic quantity-based CG method at 413 K and 1 atm by systematically examining CG simulated structural and thermodynamic properties against the…
The layered perovskite-related oxide, La <sub>6</sub> (Ti <sub>0.67</sub> Fe <sub>0.33</sub> ) <sub>6</sub> O <sub>20</sub> , with two competing magnetic interactions presents multiferroic behavior.
Quantum dots-embedded silica nanoparticles with an iron oxide NP core were prepared and exhibited super-paramagnetic and highly fluorescent properties.
