Two grades of polyvinyl alcohol (PVA) namely partially hydrolyzed (designated as PVA-I) and fully hydrolyzed (designated as PVA-II) were studied with the aim of determining the influence of PVA degree of hydrolysis on the corrosion inhibition effect of mild steel in HCl medium. The investigation was carried out using…
To clarify the origin of the major donor states in indium gallium zinc oxide (IGZO), we report measurement results and an analysis of several physical properties of IGZO thin films. Specifically, the concentration of H atoms and O vacancies (VO), carrier concentration, and conductivity are investigated by hard X-ray p…
In this work we show the effect of high temperature on the plasmonic properties of metallic nanorods. Within this context, the dielectric function of metal has been modified to keep into account both the electron–electron and electron–phonon temperature dependent scattering mechanisms. In fact, the mentioned damping p…
As the number of diagnostic and therapeutic applications utilizing gold nanoparticles (AuNPs) increases, so does the need for AuNPs that are stable in vivo, biocompatible, and suitable for bioconjugation. We investigated a strategy for AuNP stabilization that uses methoxypolyethylene glycol-graft-poly(l-lysine) copoly…
We have designed a urea functionalized novel nanoporous material, POP-PU, which showsaggregation induced white light emission in the presence of suitable polar solvents. This nanomaterial has been explored as a pseudowhite light emitter where the polymeric luminogen moiety can interact with the suitable polar solvent,…
Miktoarm-structured PEG-PCL <sub>2</sub> copolymers with morphological versatility for drug delivery.
A new method to produce cellulose nanofibrils (CNF) is proposed to reduce the energy demand during deconstruction of precursor fibers suspended in aqueous media. Microemulsions were formulated with aqueous solutions of urea or ethylenediamine and applied to disrupt interfibril hydrogen bonding. Compared to typical fib…
Development of colloidal delivery systems has opened new avenues/frontiers for improving drug delivery. Solid lipid nanoparticles have come up as the latest development in the arena of lipid based colloidal delivery systems after nanoemulsion and liposomes ever since their introduction in the early 1990s. In this revi…
This work reports a facile synthesis of palladium nanoparticles (Pd NPs) by the extract of the fruits of <italic>Piper longum</italic> without any stabilizer or surfactant.
Design of drug delivery nanocarrier having targeted recognition followed by bioresponsive controlled release, especially via glucose-responsive release, is a challenging issue. Here, we report magnetic mesoporous silica (MMS)-based drug delivery nanocarrier that can target specific cell and release drug via glucose-re…
Gold nanostars display strong electromagnetic field enhancement at their tips, and tip plasmon resonances can be tuned within the visible and near-infrared, which has been applied toward plasmonic molecular sensing. However, the sensitivity can be further increased by linking gold nanostars to other plasmonic nanopart…
Microporous organic networks (MONs) are a new class of porous materials. This work shows the application of MON chemistry for the preparation of magnetically separable catalytic systems. By the Sonogashira coupling of Fe III –tetrakis(4-ethynylphenyl)porphyrin and 1,4-diiodobenzene, Fe 3 O 4 nanoparticles were coated…
Graphene nanoribbons grown on sidewall facets of SiC have demonstrated exceptional quantized ballistic transport up to 15 μm at room temperature. Angular-resolved photoemission spectroscopy (ARPES) has shown that the ribbons have the band structure of charge neutral graphene, while bent regions of the ribbon develop a…
Both the morphology and conductivity of Cu2O films are controlled in a facile electrodeposition process by tuning the concentration of surfactants. With the increase of the concentration of sodium dodecyl sulfate (SDS) in the plating solution, the average size of Cu2O crystals increases, and the electrical conductivit…
Crystal structure of tetragonal BiOCl, field emission scanning electron micrographs, CIE chromaticity diagram and percentage of RhB dye degradation of Bi <sub>1−x</sub> Eu <sub>x</sub> OCl.
An exact analytical solution of integro-differential equations, which describe the phase transitions in supercooled binary melts, is constructed with allowance for fluctuating rates of crystal growth. A complete solution of the corresponding Fokker–Planck and balance equations is found for arbitrary nucleation kinetic…
A series of [(C^N)2 Ir(acac)] complexes [{5-(2-R-CB)ppy}2 Ir(acac)] (3 a-3 g; acac=acetylacetonate, CB=o-carboran-1-yl, ppy=2-phenylpyridine; R=H (3 a), Me (3 b), iPr (3 c), iBu (3 d), Ph (3 e), CF3 C6 H4 (3 f), C6 F5 (3 g)) with various 2-R-substituted o-carboranes at the 5-position in the phenyl ring of the ppy liga…
Aluminum complexes of non-chiral-salalen ligands were investigated in the catalysis of ring-opening polymerization (ROP) of lactide and ε-caprolactone and in their copolymerization. The aluminum-salalen complexes were found to polymerize all varieties of lactide, namely: l-, d-, rac- and meso-lactide, and showed moder…
Ceria (CeO2) is a promising dilute magnetic semiconductor. Several studies report that the intrinsic and extrinsic structural defects are responsible for room temperature ferromagnetism in undoped and transition metal doped CeO2 nanostructures; however, the nature of the kind of defect necessary to promote and stabili…
The answer to the compelling question of whether nanomaterials are new or not is debated by leading scientists.
