We have introduced an organic/inorganic hybrid pn-junction for solar cell applications. Layers of II-VI quantum dots and a metal-phthalocyanine in sequence have been used as n- and p-type materials, respectively, to form a junction. The film of quantum dots has been formed through a layer-by-layer process by replacing…
Hybrid nanocrystals of 8-hydroxyquinoline (8Hq) molecules and hydroxyapatite nanocrystals (HAp) were successfully prepared by a mechanochemical solid-state reaction. The hybrid nanocrystals exhibit a significant thermal stability and efficient photoluminescence peak at 500 nm, which were attributed to metal–ligand cha…
Abstract Metal‐infiltrated protein crystals form a novel class of bio‐nanomaterials of great interest for applications in biomedicine, chemistry, and optoelectronics. As yet, very little is known about the internal structure of these materials and the interconnectivity of the metallic network. Here, the optical respon…
Environmental monitoring studies in the Hydrographical Basin of Pardo River, RS, Brazil, in the time series from 2007 to 2009, showed no agreement between the water quality evaluation obtained through the Water Quality Index (WQI - NSF), which ranged from "regular" to "good", and the Environment National Council (CONA…
Stracchino is a short ripened soft cheese mainly produced in the North of Italy. The changes in Stracchino cheese quality are mainly attributable to microbial spoilage and structure breakdown because of enzymatic activity. The aim of this work was to evaluate the effect of different packaging materials on the shelf li…
Plasmonic interactions in a well-defined array of metallic nanoparticles can lead to interesting optical effects, such as local electric field enhancement and shifts in the extinction spectra, which are of interest in diverse technological applications, including those pertaining to biochemical sensing and photonic ci…
Experimental thermal conductivity of bulk materials are often modeled using Debye approximation together with functional forms of relaxation time with fitting parameters. While such models can fit the temperature dependence of thermal conductivity of bulk materials, the Debye approximation leads to large error in the…
We have investigated the magnetic properties of Fe doped Cd1−xFexS diluted magnetic semiconducting nanocrystalline thin films for different doping concentrations (0.05 ≤ x ≤ 0.2) synthesized by electron beam evaporation technique. X-ray diffraction patterns confirm the existence of single phase nature in all the Fe do…
Pemetrexed has been widely used as an effective chemotherapeutic agent for the treatment of a variety of cancers including breast cancer. It is a multitargeted antifolate that gets transported to cells primarily by reduced folate carrier (RFC) and exerts its action by disrupting folate-dependent metabolic processes es…
We report the fragmentation of brittle, granular aluminum spheres following high velocity impact (0.5-2.0 km/s) on thin steel plates. These spheres, machined from isostatically pressed aluminum powder, represent a prototypical metallic reactive material. The fragments generated by the impacts are collected in a soft-c…
Magnetoresistive double perovskite Sr(2)FeMoO(6) thin films were grown with two different deposition pressures on SrTiO(3), MgO and NdGaO(3) substrates by pulsed laser deposition and thorough structural, magnetic and magneto-transport characterization was made. According to x-ray diffraction, all the films were phase…
Since properties of nanomaterials are determined by their structures, characterizing nanostructure feature variability and diagnosing structure defects are of great importance for quality control in scale-up nanomanufacturing. It is known that nanostructure interactions such as competing for source materials during gr…
We have investigated electrical transport and photocurrent in single and multilayers of two-dimensional arrays of silicon nanocrystals (SiNCs) suitable for photovoltaic applications. The films were grown on quartz by low pressure chemical vapor deposition of Si and subsequent thermal oxidation steps. We found that at…
Employing first-principles density-functional-theory-based calculations, we study the electronic structure and magnetoelastic effect in difluoride compounds $M$F${}_{2}$ ($M=\text{Mn}$, Fe, Co, Ni). The magnetoelastic-effect-driven cell-parameter changes across the series are found to exhibit nonmonotonic behavior in…
Kanalisierung einer Polymerisation: Dipeptidkristalle wurden als „Reaktoren“ für Polymerisationen verwendet. Die Monomere werden in den porösen Kristallen absorbiert, und anschließende γ-Bestrahlung erzeugt Polymere mit hohen Molekulargewichten. Die Kristallkanäle bewirken einen stereoselektiven Reaktionsverlauf, der…
Single-walled carbon nanohorns (SWCNHs) dispersed with Pd-Ni alloy nanoparticles were synthesized in a technique requiring a single step by a gas-injected arc-in-water method using Pd-Ni-C mixed powders charged in an anode hole. It was found that the Ni/Pd weight ratio in the alloy nanoparticles dispersed in the produ…
High-pressure phase transformations in LiBH${}_{4}$ were theoretically investigated using first-principles density functional methods. A series of pressure-induced structural transformations are predicted in LiBH${}_{4}$, as Pnma (phase II) \ensuremath{\rightarrow} $I$4${}_{1}$/acd (phase III) \ensuremath{\rightarrow}…
Based on a generalized variational principle of magnetoelasticity and Hamilton’s principle, a dynamic theoretical model is developed for magnetoelastic vibration of a soft ferromagnetic plate with nonlinear magnetization being in a stationary magnetic field. The fundamental equations of the magnetic field and the moti…
In Norway, there are 6000 to 7000 oil-filled high-voltage cable terminations in the transmission network, most of which are constructed following the old design shown in Figure 1. Although the number of reported failures of medium-voltage cross-linked polyethylene (XLPE) cables and cable accessories is low, during the…
In this work we report the development of a rapid and selective etching strategy to synthesize a dual-yolk/shell nanostructure consisting of semiconductor-metal hybrid nanocrystals and hollow SiO2 for the first time. By utilizing CdSe/CdS/ZnS quantum dot (CSSQD)/SiO2 core/shell nanoparticles as the template and aurate…
