We report a facile route for synthesis of free standing polypyrrole–silver (PPy–Ag) nanocomposite films by photopolymerization of pyrrole using AgNO3 as photosensitizer in aqueous medium. In this process PPy–Ag films were formed at the air–water interface and at the bottom of the beaker. The films formed at the air–wa…
Green synthesis of metal nanoparticles is a growing research area because of their potential applications in nanomedicines. The green synthesis of silver nanoparticles (SNPs) is a convenient, cheap and environmentally safe approach compared to chemical synthesis. In the present study, we synthesized SNPs from AgNO 3 u…
In present studies, the synthesis of nanoparticles of silver oxide and silver chloride were carried out. The silver oxide nanoparticles were synthesized employing capping method while silver chloride nanoparticles were synthesized by simple precipitation of silver nitrate solution. Transmission Electron microscopic st…
Carbon is light-weight, strong, conductive and able to mimic natural materials within the body, making it ideal for many uses within biomedicine. Consequently a great deal of research and funding is being put into this interesting material with a view to increasing the variety of medical applications for which it is s…
Most studies have used in vitro systems to test inflammatory responses of nanoparticles; these may not reflect the real biological response of body organs. In fact, certain nanoparticles have provoked opposite effects under in vitro and in vivo conditions. Current understanding of the biocompatibility of gold nanopart…
Mesoporous uniform ammonium nickel phosphate hydrate nanostructures are successfully prepared by a one-pot hydrothermal method. As a result of the unique feature of large surface area (418 m2 g−1) and tunable mesostructures, the material exhibits good performance as supercapacitor electrodes, with a specific capacitan…
A simple photochemical technique is described for the synthesis of organized assemblies of Au nanoparticles (NPs) on a DNA template in a shorter time scale. The smaller Au nanoparticles (NPs) are initially formed in the DNA solution, self-assembled together, and generate the nanowire structures. The diameter and the l…
Nano-aggregates of cobalt nickel oxysulfide (CoNi)OxSy have been synthesized by hydrothermal processing and exhibited specific and areal capacitance as high as 592 F g(-1) and 1628 mF cm(-2), respectively, at a current density of 0.5 A g(-1)/1.375 mA cm(-2). They also show high capacitance retention upon extended cycl…
Ceria nanoparticles were synthesized employing chitosan as template and thermal treatment at different temperatures (350, 650, and 960°C). The effect of calcination temperature on structural properties and photocatalytic activity of ceria nanopowder was also tested. Degradation of an azo dye, Congo Red (CR) as a model…
A CNT-AuNP hybrid has been synthesized through the Michael addition reaction between thiol-functionalized single-wall CNT and small water-soluble Maleimide-AuNP. The resilience and stability of this hybrid nanosystem is ensured by a covalent bond linking the nanoparticle to the CNT and by the fact that the functionali…
Erbium nanoparticles (NPs) doped zinc borotellurite glasses have been prepared by conventional melt‐quenching technique with the chemical composition (where y = 0.005, 0.01, 0.02, 0.03, 0.04, 0.05). The structural properties of the prepared glasses were determined via X‐ray diffraction (XRD) analysis and FTIR analysis…
In this contribution, polypropylene (PP) nanocomposites with four different inorganic anion (CO32−, NO3−, Cl−, and SO42−) intercalated Mg3Al layered double hydroxides (LDHs) as nanofillers were prepared using a solvent mixing method for the first time. The influence of interlayer inorganic anions on the thermal stabil…
Porous carbon nanofibers (CNFs) are regarded as essential components of high-performance energy storage devices in the development of renewable and sustainable resources, due to their high surface areas, tunable structures, and good conductivities. Herein, we report new synthesis methods and applications of two types…
A series of ordered mesoporous carbon (OMC)-supported Au catalysts were successfully prepared by nano-replication, followed by colloidal gold deposition method. Structural analysis showed that the mesopore sizes of the catalysts can be tuned controllably in the range of 3.2–7.6 nm by adjusting the dosage of boric acid…
In this work, a novel efficient one-step method for preparation of acrylated soybean oil (ASO) was introduced. ASO was obtained by reacting soybean oil (SO) and acrylic acid (AA) directly under the catalysis of BF3·Et2O. Effects of reaction stoichiometry and reaction time on the conversion of the double bonds of SO we…
Electrochemical Scanning Tunneling Microscopy (ECSTM) has been employed to investigate in situ the nanometer scale morphology and the atomic structure of a (100)-oriented Fe-l8Cr-l3Ni single crystal stainless steel surface passivated in 0.5 M H 2 SO 4 (aq).The results show that polarization in the pre-passive or passi…
Mechanically enhanced aerogels of graphene sheets and carbon nanotubes (CNTs) were prepared via hydrothermal reduction of graphene oxide and CNTs in the presence of ferrous ions (FeSO4 solution). The resultant graphene–CNT aerogels possess a 3-D network of carbon structures containing micro-sized pores and α-FeOOH nan…
Nowadays, biopolymers have become more popular that is resulted from the growing concern on environmental issue and their enormous advantages. However, the application was limited by its thermal properties. Nanocomposite is one approach to increase the usability of biodegradable polymers. It is interesting to use this…
An alkoxido-bridged tetranuclear Dy(iii) complex, [Dy4(H3L)2(OAc)6]·2EtOH {, H6L = 1,3-bis[tris(hydroxymethyl)methylamino]propane}, has been solvothermally synthesized and characterized. An X-ray crystallographic study revealed that complex possesses a novel "parallelogram" [Dy4(OCH2-)4] core, and a new binding mode η…
Motivated by the recent experiments by Wang et al. (Angew. Chem., Int. Ed. 2012, 51, 6154-6157), in which the alkylamine-capped magic-size (CdSe)13 has been isolated for the first time, we report on the computational modeling of the putative low-lying isomers of (CdSe)13, both bare and ligand-protected. According to D…
