A combination of analytical and phonon-tracking approaches is proposed to predict thermal conductivity of porous nanostructured thick materials. The analytical approach derives the thermal conductivity as function of the intrinsic properties of the material and properties characterizing the phonon interaction with por…
The efficacy of drug delivery systems using nanoparticles to enhance the pharmacokinetic properties of drugs has been confirmed in both preclinical trials and clinical settings. A nanosized drug system has improved efficacy, reduced side effects and clearance, increased cellular uptake and prolonged time in circulatio…
Abstract Synthetic dyes in industrial effluents pose a significant risk to human health and the environment, so much effort has been expended to degrade them using various methods, including the use of clay minerals as catalysts. The purpose of this study was to advance understanding of the mechanisms for clay-catalyz…
The studies of the magnetic and electrical transport properties of ordered magnetic semiconductor nanostructures have been generalized. This new area lies at the intersection of nanotechnologies and fundamental problems of magnetism. The prospects for application of ferromagnetic semiconductors in spintronics have bee…
A novel method for batch fabrication of substrates for surface-enhanced Raman scattering (SERS) has been developed. A modified platen that fits in a commercial electron beam evaporator enables the simultaneous deposition of Ag nanorod arrays onto six microscope slides by glancing angle deposition. Following removal of…
This paper combines the most important results on studies performed by the authors during the last decade on photoinduced electron transfer reactions of pheophytin-, phthalocyanine-, and porphyrin-fullerene dyads, in which donor and acceptor moieties are covalently linked to each other. Practically all studied molecul…
The organization of carbon nanotubes into well-defined straight or curved geometries and arrays on surfaces is a critical prerequisite for their integration into nanocircuits and a variety of functional nanosystems. We review the recent development of a new approach to carbon nanotube organization based on self-organi…
Methods for synthesizing metal, metal oxide, and metal halide nanoparticles (NPs) in the presence of dendrimers and dendrons are discussed in this review. There are numerous reviews describing dendrimers and their properties and applications in various areas of nanotechnologies, which indicates the growing interest of…
The new mineral species brontesite , ammonium lead chloride (NH 4 ) 3 PbCl 5 , was found in a medium-temperature (~250°C) active fumarole at La Fossa crater, Vulcano, Aeolian Islands, Sicily, Italy. The mineral occurs on a pyroclastic breccia as colorless to white tabular crystals up to 0.1 mm in length, in associatio…
High performance neutron detectors sensitive to both thermal and fast neutrons are of great interest to monitor the high neutron flux produced, e.g., by fission and fusion reactors. An obvious requirement for such an application is neutron irradiation hardness. This is why diamond based neutron detectors are currently…
The self-assembled nanotube structure of poly(styrene- alt -maleic anhydride) derivatives had been previously ascribed to its favorable chirality on the polymer chain. Therefore, poly(styrene- alt -maleic acid) (SMAc) was used as a template to chelate with zinc ion and to generate SMAc-Zn with rigid-chain structure fo…
We demonstrated the use of combinatorial methods to optimize the filling of spent nuclear fuel (SNF) in metal canisters for final deep SNF repository, according to the maximal allowed thermal power per canister Pmax and the limit of n = 4 spent-fuel assemblies per canister. As a next step, the deposition time can be o…
The origin and the consequences of the electric failure of in-service composite hollow insulators used in railway transportation were investigated. Direct electrical measurements made it possible the detection of partial discharges (PD) and UV emissions allowed of identifying the location of the PD at the interface be…
We investigate the effect of the lattice topology (ideal hexagonal rings vs. ditrigonal rings) and cluster size of model clusters (three-ring vs. seven-ring clusters) on the nature of benzyl alcohol adsorption on kaolinite surfaces using quantum chemical calculations with an emphasis on the equilibrium configuration,…
Dielectric characteristics of Ba6CoNb9O30 tetragonal tungsten bronze ceramics have been evaluated over a broad temperature and frequency range. A broad dielectric peak with strong frequency dispersion is observed at 140–225 K, which well follows the Vogel–Fulcher relationship and indicates the relaxor ferroelectric na…
Yunnan Baiyao is a traditional Chinese herbal medicine that has been used to treat wounds for over 100 years. Here, we use Atomic Force Microscopy (AFM) to determine nano-scale structures of the Yunnan Baiyao. AFM images revealed uniform nanofibers present in relatively high abundance in a solution of this medicine. F…
In this study, we report the fabrication of engineered iron oxide magnetic nanoparticles (MNPs) functionalized with anti-human epidermal growth factor receptor type 2 (HER2) antibody to target the tumor antigen HER2. The Fc-directed conjugation of antibodies to the MNPs aids their efficient immunospecific targeting th…
Polymer capsules prepared by the successive adsorption of oppositely charged polyelectrolytes are modified by silver nanoparticles using the silver-mirror reaction. Substantial differences in the structure of nanocomposite polyelectrolyte shells of capsules formed on cores composed of polystyrene and CaCO 3 are reveal…
Orientation of the gap of a split ring resonator determines whether the resonance is an electric or magnetic response. When the gap of a split ring resonator is parallel to the incident E-field, an electric resonance is excited, and when the gap is perpendicular to the E-field, a magnetic resonance is excited. In this…
We analyze numerically the thermal conductivity of single-walled carbon nanotubes placed on a flat rigid substrate. We demonstrate that the character of thermal conductivity depends crucially on the interaction between the nanotube and the substrate. In particular, we reveal that unlike the well-established anomalous…
