Nanosheet transistors based on mechanically exfoliated MoS2 and other transition metal dichalcogenide layers have already been reported demonstrating good device performances. In an approach to synthesize a large area two-dimensional (2D) sheet, chemical vapor deposition methods were reported and the transfer of those…
Carbon nanotube/graphene nanoplatelet (MWCNT/GNP) hybrid membranes with lower liquid permeability and better barrier effect compared to MWCNT membranes were successfully synthesized by vacuum filtering. Their morphologies, water permeability, and pore structures were characterized by a scanning electron microscope (SE…
PURPOSE: The major limitation in the widespread use of liposome drug delivery system is its instability. Lyophilization is a promising approach to ensure the long-term stability of liposomes. The aim of this study was to prepare sirolimus-loaded liposomes, study their stability and investigate the effect of lyophiliza…
A simple and highly efficient Rh/C catalyzed route for the cleavage of the C-O bond of aromatic ether at 80 °C in the presence of 0.5 MPa of H2 in the scCO2-water medium is reported; CO2 pressure and water play a key role under the tested conditions.
Structural features and magnetic behaviour of TbPc2 thin films sublimated on LSMO and on cobalt surfaces have been investigated by synchrotron-based XNLD and XMCD techniques. Different orientation of the molecules is observed for the two substrates. No significant magnetic interaction with the ferromagnetic substrates…
A series of NNO ketoimines bearing trifluoromethyl substituents were synthesized from the Schiff base condensation of 1,3-diketones (1,1,1-trifluoro-5,5-dimethyl-2,4-hexanedione, 4,4,4-trifluoro-1-phenyl-1,3-butanedione, and 1,1,1-trifluoro-2,4-pentanedione, 1,1,1,5,5,5-hexafluoroacetylacetone) and 8-aminoquinoline or…
In situ fabrication of metal nanostructures such as metal nanoparticles (NPs) and nanoclusters (NCs) in supramolecular gels (particularly hydrogels) is important for the construction of novel and promising bio-/chemosensing platforms, and catalytic and antibacterial functional materials, because of their intriguing pr…
The adsorption of O2/H2O molecules on the ZnO nanowire (NW) surface results in the long lifetime of photo-generated carriers and thus benefits ZnO NW-based ultraviolet photodetectors by suppressing the dark current and improving the photocurrent gain, but the slow adsorption process also leads to slow detector respons…
This paper presents a micromechanical unit cell model of 5-Harness satin weave fabric textile composite for the estimation of in- plane elastic properties. Finite element modeling of unit cell at mesoscopic level has been recommended over employing costly experimental setup for such sophisticated materials. The unit c…
Shape-designed polyaniline (PANI) nanomaterials (nanoparticles, nanorods, and nanofibers) are prepared by adjusting the amount of the oxidizing agent and the monomer during chemical oxidation polymerization. The charge-transport properties of the precisely controlled PANI geometries at the nanometer scale were systema…
A strategy has been developed to produce bismuth ferrite (BiFeO3/BFO) nanotubes from electrospun nanofibers. It involves ramping the temperature to heat the as-spun BFO/PVP composite fibers to their annealing temperature using different modes, which eventually decides the final morphology of the BFO. Accordingly, we f…
Core-shell nanoparticles of sodium borohydride (NaBH4) coated with various metals have been successfully synthesised. The morphologies varied from spherical to cubic with a range of particle size distributions depending on the metal used. All core-shell structures show hydrogen storage reversibility with faster kineti…
It is fundamental to uncover the real adsorption properties of Ag clusters on an AgCl surface and the energy transfer mechanisms at the interface to understand the highly active photocatalytic performance and the stability of the plasmonic photocatalyst Ag@AgCl. Based on density functional theory calculations we provi…
The assembly behaviour of Fe3O4-capped Janus particles with magnetically and electrically anisotropic properties is investigated in overlapping external AC electric and static magnetic fields. Generally, Fe3O4 Janus particles have been shown to form double and staggered chains in external static magnetic and AC electr…
Pd nanoparticles were well dispersed on a new triptycene-based microporous polymer support by the gas bubbling-assisted membrane reduction (GBMR) method. The stability of Pd nanoparticles is improved by the porous support, and the materials show excellent performance for CO oxidation.
In this study, alumina photonic crystals (PCs) were fabricated by applying a sine-wave current in the anodization of aluminum. The effect of periodic time and peak–peak value of the current on the photonic band gap (PBG) were discussed. By selecting the appropriate experimental conditions, a full-width at half maximum…
Nanocrystalline vanadium nitride (VN) has been synthesized using a simple two-step procedure involving mechano-chemical reaction of V 2 O 3 and Li 3 N mixture induced by high energy mechanical milling (HEMM) followed by washing in water. The crystalline VN thus synthesized has been analyzed as a supercapacitor materia…
Polylactic acid (PLA), as the biodegradable polymer becomes more attention as a green material for industrial applications. Lipase-catalysed polymerization with Lecitase Ultra and Lipozyme TL IM were applied to synthesize PLA to decrease the chemical-catalysts utilization which having toxicity interferes in products.…
Shape-controlled synthesis of CoCO3 crystals is achieved by a mild template- and surfactant-free solvothermal process. On switching the volume ratio of ethylene glycol (EG) in the mixed solvent, the structures of the CoCO3 crystals change from cantaloupe-like patterns to microcubes. The formation pathway of CoCO3 was…
We present a kinetic model to investigate the anomalous thermal conductivity in silicon nanowires (SiNWs) by focusing on the mechanism of phonon-boundary scattering. Our theoretical model takes into account the anharmonic phonon-phonon scattering and the angle-dependent phonon scattering from the SiNWs surface. For Si…
