Abstract:

Chitosan as a natural biopolymer has been produced to be the important host for the preparation of metallic nanoparticles (MNPs) because of its excellent characteristics like:- good stabilizing and capping ability, biocompatibility, biodegradability, eco-friendly and non-toxicity properties. Chitosan can play a very important role for synthesis of metallic nanoparticles, as chitosan is a cationic polymer. It attracts metal ions and reduces them and also Capps and stabilizes. So basically chitosan can be responsible for the controlled synthesis of metallic nanoparticle. Chitosan has a very good

Abstract:

Particulate matter is associated with different human diseases affecting organs such as the respiratory and cardiovascular systems. Very small particles (nanoparticles) have been shown to be rapidly internalized into the body. Since the sites of internalization and the location of the detected particles are often far apart, a distribution via the blood stream must have occurred. Thus, endothelial cells, which line the inner surface of blood vessels, must have had direct contact with the particles. In this study we tested the effects of metallic nanoparticles (Co and Ni) on oxidative stress and

This review focuses on the surface modification of metallic nanoparticles for targeted drug delivery. Metallic nanoparticles, owing to their unique size, stability, and payload capacity, have emerged as promising drug carriers. However, their application necessitates surface modification to enable precise targeting.

The review also discusses the selection of ligands based on target receptors, active and passive targeting approaches, and stimuli-responsive

Hydrogen storage in a metallic nanoparticle was simulated by classical molecular dynamics. Distribution of hydrogen atoms inside nanoparticle was investigated by changing length and energy parameters of metal– H bonds. Hydrogen atoms diffused into the particle and distributed homogeneously in case of weak metal– H bonds. In case of strong metal– H bonds, a hydrogen-rich surface layer was observed which suppresses the inward diffusion of hydrogen atoms. Structural modification of nanoparticle accompanied by grain boundary formation due to hydrogen loading was also observed. These variations in

Abstract:

Over the past several years, coherent interface strengthening was proposed and has since drawn much attention. Unfortunately, many fabrication techniques are restricted to very small size. Recently, a brand new method of in-situ nanoparticle strengthening was systematically investigated, which was proved to be an efficacious way to optimize microstructure and improve mechanical property by utilizing uniformly dispersed nanoparticles. In this review, we summarized recent related advances in investigated steels and Cu alloys, including details of preparation technique and characterization of in-

Abstract:

An analytical expression was obtained for the variation of the work function of a metallic nanoparticle in comparison with its value for the flat surface of the bulk corresponding metal as a function of the nanoparticle radius and its charge. It was demonstrated, that the work function for electroneutral nanoparticles starts to diminish essentially for the small radii of 2 nm and less. However, even a single elementary charge, placed on nanoparticle, makes the variation of the work function essential for its radius of 10 nm order, and this effect increases with the increase of the charge.

Abstract:

Nanotechnology belongs to the key innovative technologies for powder production. Ultrasonic spray pyrolysis is a versatile method for the formation of nanosized particles of metals, oxides and composites. This work deals with Ag, Cu and Au nanoparticles formed by ultrasonic spray pyrolysis using the horizontal and vertical reactor. Furthermore, a direct synthesis of Ru-TiO2 and RuO2-TiO2 nanoparticles with the core and shell structure was investigated. The molar fractions of precursors, solvent type, and the process temperature play the crucial role in the formation of core and shell structure

In this article, we study the novel features of morphological effects for hybrid nanofluid flow subject to expanding/contracting geometry. The nanoparticles are incorporated due to their extraordinary thermal conductivity and innovative work for hybrid nanofluids, which are assembled of aluminum oxides, Al2O3 metallic oxides, and metallic copper Cu. Cu nanoparticles demonstrate very strong catalytic activity, while Al2O3 nanoparticles perform well as an electrical insulator.

Abstract:

A versatile one-step pyrolysis method is successfully employed to fabricate hollow carbon nanospheres (HCNs, ca. 60 nm in diameter) supported with metallic nanoparticle catalyst. The resultant catalyst hybrid was characterized by using TEM, FTIR, TGA measurements. It is confirmed that, as the carbon precursor and hollow core/shell structure template, hollow chitosan nanospheres provide the important adsorption sites for the metallic precursor. The one-step pyrolysis process at 750 °C under nitrogen atmosphere results in the simultaneous decomposition of the chitosan nanospheres to HCNs and the

Metallic nanoparticle ensemble, with narrow inter-particle distance, is a useful element for diverse optical devices due to highly enhanced electric field intensity at the gap. Self-assembly of block copolymer (BCP) can provide the versatile solution to fabricate precise nanostructures, but this methodology has the intrinsic limitation to realize optically coupled metallic multimer geometry with narrow inter-particle distance. This is because BCP-based nanotemplate possesses a minimum size limit for interparticle distance imposed by its thermodynamic restriction. Herein, we investigate the fac

The article examines the impact of plasmon excitation on the surface of a spherical metallic nanoparticle on its catalytic properties, specifically the efficiency of hot electron generation (activity). The physical mechanisms behind the enhancement of catalytic activity under resonant excitation of surface plasmons are described. A mathematical model is proposed within the classical approximation to describe the relationship between the optical and catalytic properties of metallic nanoparticles. The model accounts for volumetric, surface, and radiative mechanisms of electron relaxation in the
