We study the sedimentation of an initially inhomogeneous distribution of binary colloidal mixtures confined to a slit using a coarse-grained hybrid molecular dynamics and stochastic rotation dynamics simulation technique. This technique allows us to take into account the Brownian motion and hydrodynamic interactions b…
MoN nanoparticles in a size range around 50 nm were obtained on CNTs support via a novel carbothermal reduction nitridation (CRN). For the first time, a common (NH4)6Mo7O24·4H2O can be used as a Mo source to prepare MoN nanoparticles. A Mo-containing precursor was in a first step carburized and was reduced to a MoOxCy…
P-type ZnO microbelts were successfully synthesized by thermal diffusion of Ag in a step by step thermal annealing process. The effect of the annealing temperature on the room temperature photoluminescence (RT-PL) and current versus voltage (I–V) properties of Ag-doped ZnO microbelts were studied. With the increase of…
The rectangular shaped hollow polyaniline (PANI) tubes prepared by in situ Acid Red 8 (AR8) crystals as templates provided a sustained release of the entrapped dye and their release behavior was dependent on the environmental pH.
Abstract The dynamics of the Liesegang type pattern formation is investigated in a centrally symmetric two-dimensional setup. According to the observations in real experiments, the qualitative change of the dynamics is exhibited for slightly different initial conditions. Two kinds of chemical mechanisms are studied; i…
Metallic nanoparticles with a unique morphology were produced by combining bottom-up nucleation/growth and top-down etching for Au core-Pt shell nanoparticles. Interesting optical and electrocatalytic properties were observed for the newly formed shapes.
We employ fully atomistic molecular dynamics simulations to study in detail the mechanisms involved in the non-covalent association of the bioactive agent Shikonin with the commercially available hyperbranched polyesters (Boltorn®), in ethanol solutions. We examine effects of the (pseudo)generation of the hyperbranche…
Three different Aspergillus Niger MTCC strains (872, 1785 and 2208) were used for the production of chitosan. Multivariate growth mediums in varying incubation periods were analyzed for the production. The produced chitosan was characterized by its physical appearance, moisture content (by means of gravimetric method)…
Different pattern structures are obtained on the AgInSbTe (AIST) phase change film as induced by laser beam. Atomic force microscopy (AFM) was used to observe and analyze the different pattern structures. The AFM photos clearly show the gradually changing process of pattern structures induced by different threshold ef…
The formation of fiber networks and the resulting rheological properties of supramolecular soft materials are dramatically influenced when the volume of the system is reduced to a threshold. Unlike un-confined systems, the formation of fiber networks under volume confinement is independent of temperature and solute co…
GaN-on-sapphire structure with a Ga 2 O 3 sacrificial layer was employed for the chemical lift-off process application. The ( 01) β-oriented Ga 2 O 3 thin film was first deposited on the c-plane sapphire substrate using pulsed laser deposition, followed by the GaN growth via metalorganic vapor phase epitaxy under N 2…
CuO nanoparticles have been synthesized by the hydrothermal route using two different organometallic and inorganic precursors of copper acetylacetonate [Cu(C5H7)2:Cu(AA)2] and hydrated copper nitrate [Cu(NO3)2.3H2O], respectively. Detailed structural and vibrational studies have been carried out using x‐ray diffractio…
A systematic analysis of the effect of oxygen concentration in inert gas environments on friction and wear properties of carbon nitride (CNx) coatings is discussed in this paper. The friction tests in inert gas environments with constant and increasing oxygen concentration were performed using a ball-on-disk tribomete…
A series of meso-meso, β-β, β-β triply linked linear, radial and square-type zinc(II) porphyrin arrays consist of the constituent porphyrin units and naphthalene junctions. To understand the unique nature of triply linked porphyrin arrays, numerous research activities have been focused on the electronic structures of…
Bi(0.9)Sm(0.1)Fe(1-x)Mn(x)O(3), with x=0.00, 0.15, 0.30 have been synthesised by solid-state reaction. The structures of the materials, characterised via Rietveld analysis of high resolution powder neutron diffraction data, reveal a structural transition from R3c to orthorhombic Imma symmetry is complete for the x=0.3…
The partially-oxidized TPP[M(Pc)L(2)](2) molecular conductors exhibit variable electronic and magnetic transport bulk materials properties due to central metal and axial ligand molecular modifications. The controllable electrical conductivity and giant negative magnetoresistance can be mainly attributable to the varyi…

The dielectric properties of pure nematic liquid crystal (BKS/B07) and dye doped (Rhodamine B and Anthraquinone) nematic liquid crystal have been investigated in a wide frequency range of 1 kHz to 10 MHz through the dielectric spectroscopic method at varying temperature. In addition to this optical transmittance and t…
Fully dense nanostructured SiC ceramics were fabricated by spark plasma sintering of nanosized β-SiC powder with 40 nm in diameter through liquid-phase sintering at the total content of 10 vol % of sintering additives composed of 95 mol % AlN and 5 mol % Y2O3. The dense SiC ceramics sintered at 1900°C for 300 s consis…
We report the encapsulation of negatively charged Au nanoparticles and anionic fluorescent (FL) dye in the inner cavity of redox-active cationic polymer nanotubes with viologen via electrostatic interaction and the release of the FL dye from the FL dye confined in the cavity of the polymer nanotubes by electrochemical…
