Synthesis of NaYF4 nanocrystals with well-defined shapes and/or architectures has been of great interest in recent years, owing to their unique optical properties and wide applications in biological fields. NaYF4 nanocrystals with conventional morphologies have been developed through a variety of chemical or physical…
Methods based on fluorescence technology have been widely employed to analyse protein function, dynamics, interactions and folding in cell free systems as well as in intact cells. Fluorescence resonance energy transfer (FRET) is a unique technique to precisely calculate inter- and intra-molecular distances in proteins…
Co(III) sarcophagine-type cage molecules, [Co(diCLsar)](3+) or [Co(HONOsar)](3+), form either 1 : 1 or 1 : 2 host-guest inclusion complexes with mono-phosphonium cations and sodium p-sulfonatocalix[4]arene in the solid state yielding complex I [p-sulfonatocalix[4]arene·Co(diCLsar)·2{benzyltriphenylphosphonium}], compl…
The constructional fine-grained steel S460 shows considerably high fatigue performance. In the last two decades this material has been investigated experimentally in great detail. These results served as basis for developing models and algorithms aiming at improvement of fatigue life assessments. The paper summarizes…
Dissimilar metal welds of filler metal 182 (ENiCrFe-3) in the primary loop of pressurized water reactor (PWR) nuclear plants are susceptible to primary water stress corrosion cracking (PWSCC) after decades of service. Repair or mitigation has been routinely accomplished by installing a structural weld overlay (SWOL) o…
Formation of titanium-oxide structures during multiple sequential treatment of finely porous silica by TiCl 4 and H 2 O vapors at 200, 350, and 500°C was considered. Temperature of the synthesis affects the regularity the buildup and phase composition of formed surface titanium-oxide structures. The reaction products…
Gold nanoparticles (NPs) were assembled and cross-linked into spherical aggregates by colloidal emulsion evaporation and ligand exchanging. The optical absorption, conventional transmission electron microscopy (TEM) and bright field (BF) TEM tomography confirm that the cross-linking of the pre-condensed aggregates gen…
Electron energy distribution function (EEDF) extraction from Langmuir probe data is an ill-posed problem due to the integral relationship between electron current and probe voltage. Both curve fitting of experimental data and reconstruction of the integral problem through methods, such as Tikhonov regularization, addr…
Low temperature bonding of wafers coated with low-κ dielectric film of carbon-doped oxide (CDO) is demonstrated. Direct bonding is successfully achieved by using oxygen plasma activation which modifies the low-κ CDO surface to be more hydrophilic. It is discovered that after a 300°C anneal in N 2 ambient for 3 h, bond…
The samples of Polycarbonate (PC) have been implanted to 100 keV Ar+ ions at the fluences 5×1015–2×1016 cm−2. It has been observed that the surface conductivity of these implanted samples enhances with increasing implantation dose. Such an increase in the conductivity may be as a result of the formation of conjugated…
The results of B3LYP/6-31G(d) calculations show that there is a strong cooperative effect on the energies that result from annelating benzene with 1, 2, and 3 etheno groups, to form 3, 4, and 5 respectively. The etheno annelation energies have been decomposed into two major contributors – etheno annelation, with all t…
DCJ, one of the DCM derivatives, has been used as a laser dye and a red emitter or a red dopant for OLED devices in recent decade. 4-(dicyanomethylene)-2-methyl-6-(julolidyl-9-enyl)-4H-pyran (DCJ) containing julolidine group has been synthesized for use as a red fluorescent dye molecule in organic light-emitting di- o…
The oxyanions (NO3−, CO32−) and phenoxyacetate (PhOAc−) bridged three 1D-coordination polymeric chains, {[Cu2(μ-hep)2(μ-NO3)]2}n (1), {[Cu2(μ-hep)2(H2O)2]·2H2O(μ-CO3)}n (3) and {[Cu2(μ-hep)2(μ-PhOAc−)]2}n (2) (hep-H = 2-(2-hydroxyethyl)pyridine) have been synthesized. In 1–3 the alkoxide bridged dicopper building unit…
The Polycyclic Aromatic Hydrocarbons (PAHs) are the most widespread organic environmental pollutants. PAHs are found in motor vehicle exhaust. Some PAHs are found in medicines, dyes, plastics, pesticide, naphthalene balls and wood preservatives. The compounds under the presences of Sun light generally activated and in…
Multilayer structure of Tin Selenide thin films were prepared by thermal evaporation technique by successive coatings of Tin and Selenium metal powders. The number of layers varied from 3 to 11 during deposition on the glass substrate with 423 K temperature. The optical properties of the multilayer films studied using…
We experimentally show the detailed electrical transport characteristics of an SnO2 nanomaterial with three-branch junction morphology, termed the nanowire T-junction. By contacting the three branches of a T-junction as the gate, source and drain, some control and tunability has been achieved over the output current,…
Sodic water and spring water percolated through clay, clay loam, and sandy loam (SL) soils with exchangeable sodium percentages (ESPs) of 0, 10, 30, and 50. Reduction in saturated hydraulic conductivity and water stable aggregates recorded at higher ESPs. At ESP ≈30, application of sodic and spring water to clay soil…
The execution of residual strain measurements using neutron diffraction in order to determine the residual stress state in a material or component is now a well-established method. The analysis of the uncertainty of the resultant strain and stress is a topic that is frequently brought into discussion. There are many s…
Abstract In this work, we have calculated the expected properties of the Electron Bernstein Wave (EBW) heating using the O–X–B double mode conversion scenario in a plasma that evolves from Electron Cyclotron Resonance (ECR) to Neutral Beam Injection (NBI) heating in the TJ–II device. For this purpose, a transport simu…
A new small modular reactor (SMR) is proposed for a 300 MW(e) nuclear generating station. It is referred as the SuperSafe© Reactor (SSR) and is a scaled down version of the Canadian supercritical water-cooled reactor (SCWR), which is designed to operate at supercritical conditions (pressure of 25 MPa and fluid tempera…
