The electronic and adsorption properties of dimethyl and methyl-ethyl ester molecules on a silicene nanoring (SiNR) are studied using first-principles calculations. The adsorption properties of dimethyl and methyl-ethyl ester molecules on the surface of a silicene nanoring is investigated in terms of density of states…
Manganese substituted Cobalt Ferrite Co1-xMnxFe2O4() nanoparticles were prepared using low temperature chemical co-precipitation method. All the samples were annealed at 900°C for 3 hours. The crystal lattice symmetry and phase purity were performed by X-ray diffraction (XRD). The varying dopent concentration affects…
Abstract The band alignment at a coherent α-Ga 2 O 3 /Al 2 O 3 heterointerface was evaluated by analyzing X-ray photoemission spectra for an α-Al 2 O 3 film and an α-Ga 2 O 3 /Al 2 O 3 multi-quantum wells grown coherently on sapphire substrates. The measured bandgaps of α-Ga 2 O 3 and α-Al 2 O 3 were 5.7 and 8.7 eV, a…
Electrostatic charge doping in graphene by ferroelectric polarization is an intriguing avenue for graphene-based nanoelectronic devices. Here, on the basis of the thermodynamically stable BiFeO 3 (0001) surfaces, we present first-principles calculations to study the influence of surface termination on interface chemis…
Abstract Micro-Extinction Spectroscopy (MExS), a flexible, optical, and spatial-scanning hyperspectral technique, has been developed and is described with examples. Software and hardware capabilities are described in detail, including transmission, reflectance, and scattering measurements. Each capability is demonstra…

Bipolar electrochemistry (BPEC) is a versatile and powerful technique that has found applications in sensing, chemical synthesis, catalysis, fuel cells, and batteries, among others. In BPEC, the reactions of interest occur at a wireless, bipolar electrode (BPE). BPEC is most commonly carried out in an electrochemical…
Graphene and its derivatives have been demonstrated to be good surface-enhanced Raman scattering (SERS) substrates. However, the literature offers some contrasting views on the SERS effect of graphene-based materials. Thus, understanding the mechanism of the SERS enhancement of graphene is essential for exploring its…
We present simulations of quantum transport in graphene p-n junctions $(pn\mathrm{Js})$ in which moir\'e superlattice potentials are incorporated to demonstrate the interplay between $pn\mathrm{Js}$ and moir\'e superlattice potentials. It is shown that the longitudinal and Hall resistivity maps can be strongly modulat…
In this paper, the plasmonic resonant absorption of gold nanorods (GNRs) and GNR solutions was studied both numerically and experimentally. The heat generation in clustered GNR solutions with various concentrations was measured by exposing them to Near Infrared (NIR) light in experiment. Correspondingly, calculations…
Technology transfer from laboratory into practical application needs to meet the demands of economic viability and operational simplicity. This paper reports a simple and convenient strategy to fabricate large-scale and ultrasensitive surface-enhanced Raman scattering (SERS) substrates. In this strategy, no toxic chem…
In spite of intensive research investigating the prevalent Pt/Al 2 O 3 catalysts, achieving macroscopic morphology beyond the powder form limitations remains highly challenging. Meanwhile, current impregnation-based preparation approaches show the drawbacks of tedious procedures and inefficient use of noble metals. Th…
The Cl exchange reaction of hexachlorocyclotriphosphazene, N3P3Cl6 (1), with one equimolar amount of sodium salt of N/O donor type bidentate ligand containing a 2-pyridyl pendant arm (2) afforded, regioselectively, the partly substituted 2-pyridyl(N/O)spirocyclotriphosphazene (3; with a yield of 65%) in THF. The react…
Abstract Pure and Fe‐doped Al 2 O 3 nanoparticles ( NP s) were synthesized with different iron doping percentage of 1, 3, and 5 mol% employing sol gel technique with AlCl 3 , FeCl 3 as well as ethylene glycol ( EG ) and Polyvinylpyrrolidone ( PVP ) stabilizers as precursors. The XRD results indicated that the hexagona…
Utilization of electrospinning technique accompanied by chemical modification as well as, the production of low-cost adsorbent based on polyamide nanofibers is the aim of our current work. The electrospinning parameters (polymer conc., applied voltage, and collector distance) have been studied. The obtained polyamide…
Recent technical progress demonstrates the possibility of stacking together virtually any combination of atomically thin crystals of van der Waals bonded compounds to form new types of heterostructures and interfaces. As a result, there is the need to understand at a quantitative level how the interfacial properties a…
The aim of our research was to produce poly(lactic acid) (PLA) fibres with diameters in the micrometer size range, serving as the reinforcing phase in self-reinforced (SR) PLA composites. Nonwoven PLA mats were manufactured by solvent-free melt-blowing technology. Three types of PLA differing in d-lactide content were…
Four rare-earth-metal aryloxo complexes stabilized by a tetradentate Salan ligand were prepared, and their catalytic properties for the (co)polymerization of lactides and ε-caprolactone were elucidated.
