In this work, we investigated the effects of the ambient liquid medium on the size, optical and stability properties of gold nanoparticles synthesized by electrical explosion of wire. The explosion process was carried out in deionized water, cetyl trimethyl ammonium bromide (CTAB), sodium dodecylbenzenesulfonate (SDBS…
Abstract Efficient algorithms for the simulation of strained heteroepitaxial growth with intermixing in 2+1 dimensions are presented. The first of these algorithms is an extension of the energy localization method [T. P. Schulze and P. Smereka, An energy localization principle and its application to fast kinetic Monte…
Calcium fluoride (CaF 2 ) nanoparticles were synthesized by co-precipitation method and characterized by powder X-ray diffraction (PXRD), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM). Also, optical absorption (OA) and photoluminescence (PL) studies on gamma irradiated (-rayed) CaF…
Zinc Sulfide (ZnS) quantum dots of sizes 2.68-4.8 nm, embedded on polyvinyl alcohol (PVA) matrix, have been synthesized at 70C by chemical route. X-ray diffraction (XRD), High Resolution Transmission Electron Microscopy (HRTEM), Scanning Electron Microscopy (SEM), UV-VIS Spectroscopy and Photoluminescence (PL) Spectro…
Abstract: Interfacial strength between polymeric matrix and natural filler reinforcement has direct effects on the properties of wood plastic composites. There are some approaches to improve the interfacial adhesion between two phases in wood plastic composites. One of them is using coupling agents to improve the comp…
Abstract. In the studies of aquatic ecology, periphyton has been uncared for despite its vital role in nutrient uptake and transfer to the upper trophic organisms. Being the component of food chain as attached organism it takes part in nutrient cycling in the ecosystem like that of suspended planktonic counterparts. T…
The electrochemical halogenation of polythiophene derivatives (PTs) such as poly(3-hexylthiophene) (PHT), poly(thiophene-alt-9,9-dioctylfluorene) (PTF) and poly(bithiophene-alt-9,9-dioctylfluorene) (PBT) was investigated using a thin-layered cell. The reactivity and the current efficiency of the electrochemical haloge…
We developed a simple solvothermal approach to synthesize hollow Mn ferrite nanostructures. A mixture of ferric stearate (Fe(SA)3) and manganese stearate (Mn(SA)2) reacted with [Fe3+]/[M2+] ratio = 1 : 1 in 1-octanol solvent at 240 °C. No additional capping agent was necessary in this reaction. Transmission electron m…
Ligands based on carbo- and thio-carbohydrazone cores, modified with pyridine, carboxylate and oxime ends, have been examined. They display a tautomeric versatility based on the flexible nature of the hydrazone linkages, leading to varied coordination motifs. Examples of mononuclear (Co(II), Ni(II)), dinuclear (Co(III…
LaCo(2)As(2) can be synthesized as pure crystalline material by annealing a mixture of elements in Bi flux. The reaction, however, is accompanied by the incorporation of a small quantity of Bi into the structure and the formation of vacancies in the Co sublattice, which lead to substantial changes in structural and ma…
Surface-enhanced Raman spectroscopy (SERS) was used as a powerful surface analyzing tool to investigate the core-shell structural evolution of Au@Pt nanoparticles, revealing the templating role of the underlying Au atoms on the nanoscale Pt-phase structure in the sub-monolayer range.
Ordered assembly of ultra-small nanoparticles or nanoclusters remains a challenge due to their large surface energy induced ripening and isotropic aggregation. In this communication, an in situ formation and assembly of ultra-small gold nanoclusters at the oil/water interface was developed to assemble gold nanocluster…
This work describes a novel process for the fabrication of hybrid nanostructured particles showing intense tunable photoluminescence and a simultaneous ferromagnetic behavior. The fabrication process involves the synthesis of nanostructured porous silicon (NPSi) by chemical anodization of crystalline silicon and subse…
Organic–inorganic hybrids, based on the Lindqvist-type polyoxometalate (POM) and dioxomolybdenum(VI) complexes, have been synthesized by hydrolysis of [MoO2(acac)2] (acac = acetylacetonate) in the presence of aroylhydrazone ligands in weak donor solvents. This provides an efficient route to materials that contain open…
The recent mechanistic finding of the hydrogen release pathways from ammonia borane (AB) has sparked new interest in the chemistry and properties of the diammoniate of diborane (DADB), an ionic isomer of AB. We herein report a facile one-step solid-phase synthesis route of DADB using inexpensive starting materials. Ou…
Interferometric lithographically fabricated porous carbon acts as active substrates for Surface Enhanced Raman Scattering (SERS) applications with enhancement factors ranging from 7 to 9 orders of magnitude.
This study presents an innovative synthetic route to Li3N@carbon composites for the purpose of use as hydrogen storage materials. The synthesis method is provided by wet impregnation of mesoporous carbons (graphitic or non-graphitic) using lithium azide solutions, followed by a thermal treatment allowing the transform…
The aim of this article is to highlight the use of nitrile-functionalized poly(alkylidenamines) dendrimers as building blocks for the preparation of low-generation ruthenium based cationic metallodendrimers having in view potential biomedical applications. Air-stable poly(alkylidenamines) nitrile dendrimers, periphera…
Hydrogen electro-oxidation kinetics at the Pt | CsH2PO4 interface have been evaluated. Thin films of nanocrystalline platinum 7.5–375 nm thick and 1–19 mm in diameter were sputtered atop polycrystalline discs of the proton-conducting electrolyte, CsH2PO4, by shadow-masking. The resulting Pt | CsH2PO4 | Pt symmetric ce…
Capsosomes, polymer hydrogel capsules containing intact liposomal subcompartments, represent a promising platform toward the assembly of cell-like systems. Compartmentalized assembly plays a key role in the creation of therapeutic artificial cells, which focuses on enzymatic activities to degrade waste products or to…
