Nanoparticle biosynthesis using the extract of medicinal plants in a non-hazardous mode has gained wide attention for various applications in nanomedicine.
Granular starches grafted with polycaprolactone (St-g-PCL) were obtained using N-methylimidazole (NMI) as a catalyst. The effect of the starch/monomer ratio and catalyst content was studied to obtain different levels of grafted PCL. The highest grafting percentage (76%) and addition (43%) were achieved for reactions w…
Cerium oxide nanoparticles (CeO2 NPs) were synthesized through chemical (co-precipitation method) (C-CeO2 NPs) and green synthetic route (A. indica leaf extract) (G-CeO2 NPs) and comparative studies were also carried out in the first time. From the XRD Pattern of C-CeO2 and G-CeO2 NPs revealed that both were in cubic…
This study reports the occurrence of a special red-emitted anodic electrochemiluminescence (ECL) emission at +1.4 V (vs. Ag/AgCl) on a glass carbon electrode (GCE) after the addition of thioglycol (TG) to surface-unsaturated glutathione (GSH)-coated Au nanoclusters (NCs), with an emission peak at ∼630 nm. Compared to…
The effect of two essential oils (EOs), from Origanum vulgare and Origanum majorana , their structural properties, and concentration on physical and antimicrobial characteristics of chitosan based solutions as well as films was investigated. Results showed that significantly different behaviour was induced by variatio…
Improved magnetism and magnetodielectric coupling are obtained in plate-like BaFe <sub>12</sub> O <sub>19</sub> nanoparticles because of their larger structural distortion.
Hierarchically nanostructured arrays of network-loaded ZnO nanorods for use in enhanced UV photodetectors based on the Taguchi approach.
A type of carbon nanocages has been constructed through grilling of turbot by a facile method, and applied successfully as a fluorescent probe for rapid, selective as well as sensitive detection of ascorbic acid.
It is known that defects strongly influence the properties of two-dimensional (2D) materials. The controlled creation and removal of defects can be utilized to tailor the optical and electronic responses of these 2D materials for optoelectronic and nanoelectronic applications. In this study, we developed an efficient…
Colloidal metal nanocrystals find many applications in catalysis, energy conversion devices, and therapeutics. However, the nature of ligand interactions and implications on shape control have remained uncertain at the atomic scale. Large differences in peptide adsorption strength and facet specificity were found on f…
Thermal transport across solid interfaces plays important roles in many applications, especially in the thermal management of modern power electronics. In this study, we use non-equilibrium MD (NEMD) simulations to systematically study a model SiC/GaN interface, which is an important interface in GaN-based power elect…
Inferior water barrier performance has always been a major deficiency of polylactide (PLA) that is in practice difficult to overcome owing to the existence of plentiful hydrophilic ester bonds in the main chain.
A single Ni atom substituted on a ZnO surface is a promising catalyst for the water gas shift reaction.
) and large templated mesopore diameters (up to 18.6 nm) was synthesized based upon a simple yet efficient copolymerization-induced self-assembly process of aniline/pyrrole co-monomers and block copolymer templates. The PCNSs exhibited enhanced adsorption properties towards creatinine and superior lithium-sulfur batte…
Shaking graphite powder dispersed in an aqueous alkaline cellulose solution produces stable dispersions of hydrophilic, thin graphite sheets with lateral dimensions reaching many micrometers. The X-ray diffractogram and Raman spectrum of the exfoliated graphite differ from the well-known graphite patterns. Analytical…
, and reveal the NR position-dependent Raman scattering characteristics of the phonon modes per given light-matter interaction geometry. We then present Raman intensity maps and elucidate Raman behaviors consistent and incongruous with Raman selection rules. In particular, we identify an intriguing Raman scattering ph…
High corrosion inhibition effectiveness of 2-aminobenzimidazole is proven after a long-term immersion period in 3 wt% NaCl solution.
Production and wide application of nanomaterials have led to nanotechnology development but their release to environment and the induction of toxic reactions, affects the natural microbial communities. Therefore, studies on the impact of nanoparticles on microorganisms and environment are required and needed. The aim…
In this work, a trivalent chromium conversion coating applied on AA2024-T351 alloy has been optimized for corrosion protection in sodium chloride solutions. Scanning electron microscopy, energy dispersive X-ray spectroscopy and electrochemical measurements were employed to characterize the coating. An immersion post-t…
Sub-nanometer [Ag <sub>2</sub> ] <sup>2+</sup> and [Ag <sub>m</sub> ] <sup>n+</sup> were highly stabilized in inorganic glass to achieve heavy doping and high luminescence QYs.
