Probing Higher Order Surface Plasmon Modes on Individual Truncated Tetrahedral Gold Nanoparticle Using Cathodoluminescence Imaging and Spectroscopy Combined with FDTD Simulations

We report the spatial maps of the localized surface plasmon resonances associated photon emission in a truncated tetrahedral gold nanoparticle on a silicon substrate. Site-specific cathodoluminescence spectroscopy and imaging in a scanning electron microscope shows stronger photon emission in the visible range near the tips of the particle in contact with the substrate compared to the edges of the particle. Strong local field variations on a length scale as short as 19 nm are resolved. We also perform FDTD simulations of both the spectra and, for the first time, the full cathodoluminescence images. Excellent agreement is obtained with the experimental results, and the detailed information available from the simulated results makes it possible to identify the signature of out-of-plane higher order modes in the truncated tetrahedral gold particle.
Infrared Laser-Induced Photo-Thermal Phase Transition of an Aqueous Poly(N-isopropylacrylamide) Solution in the Micrometer Dimension.

The phase transition of an aqueous poly(N-isopropylacrylamide) solution (PNIPAM, wt% = 1.8—3.6%) was induced by the irradiation of a focused (ca. 1 μm) 1064-nm laser beam; this brought about the formation of a single PNIPAM microparticle. The diameter of the particle was controlled to 2—9 μm through the laser power, polymer concentration, and solution temperature. The primary origin of particle formation was the photo-thermal phase transition of the polymer solution through the local heating of water (H2O) by the laser beam. The characteristic features of the phenomena, including manipulation of the PNIPAM particle by the incident laser beam and the role of radiation force for the particle formation, are discussed.
Hydrogen Sorption onto Hypercrosslinked Polymer Decorated with Metal-Organic Framework

Metal-organic framework decorated styrene-maleic acid (SMA) co-polymer beads were synthesized by slow diffusion of TEA. The obtained materials were characterized by FTIR, scanning electron microscopy, and thermogravimetric analysis. The different dicarboxylic acid linkers influenced the crystal morphologies and hydrogen-storage behavior of the polymer beads. Hydrogen-storage measurements revealed slow micropore opening mechanism involved in adsorption of hydrogen.
Measurement of Temperature-Independent Femtosecond Interfacial Electron Transfer from an Anchored Molecular Electron Donor to a Semiconductor as Acceptor

Modified perylene chromophores were adsorbed with virtually constant reaction distance on the surface of a spongelike TiO2 electrode. Interfacial electron transfer was probed with femtosecond resolution in ultrahigh vacuum via transient absorption and fluorescence up-conversion measurements. Identical time constants were measured for the decay of the reactant and rise of the product states. The dominant fast time constant was 190 fs. It remained constant between 300 and 22 K.
Quality changes and storage life of common carp (Cyprinus carpio) at various storage temperatures

The shelf life and freshness changes in pond-grown common carp (Cyprinus carpio L) during storage at 0–2°C, 5–6°C and room temperature (26–29°C) were investigated by sensory, microbiological, physical and chemical analyses. The effect of gutting on the shelf life during storage at 0–2°C was examined. Iodine/starch and potassium sorbate were examined for their effects on shelf life of whole fish stored at 0–2°C and 5–6°C. Sensory results indicated that the whole fish had a maximum shelf life of 24 to 25 days at 0– 2°C. The life of the fish to the point beyond which it would be unsuitable for sale (commercial shelf life) was 17 days at 0–2°C. Storage at 5–6°C shortened shelf life 2- to 2.5-fold. At room temperature (26–29°C), spoilage was evident after 13 h. Gutting the carp shortened its storage potential at 0–2°C. Iodine treatment of this species stored at 0–2°C and at 5–6°C did not extend shelf life. The maximum shelf life of sorbate-treated fish at 0–2°C and 5–6°C was extended by 1–2 days, commercial shelf life by 3–4 days. Total volatile basic nitrogen, pH and penetrometer analyses were not reliable indicators of changes in freshness during shelf life. Thiobarbituric acid values were not useful as rancid odours or flavours were not detected during storage.
Ligand Controlled Highly Selective Copper-Catalyzed Borylcuprations of Allenes with Bis(pinacolato)diboron

Copper-catalyzed highly selective borylcuprations of allenes with bis(pinacolato)diboron produce two different types of alkenylboranes by applying a ligand effect. In the presence of tris(para-methoxyphenyl)phosphine [P(C6H4OMe-p)3], the reaction of aryl-1,2-dienes affords 2-alken-2-yl boronates as the only product with exclusive Z-geometry; the regioselectivity is switched to afford the 1-alken-2-yl boronates as the major products when the bidentate phosphine 2,2′-bis(diphenylphosphino)biphenyl is used as the ligand.
Crystal stability of diblock copolymer micelles in solution

We investigate the relative stability of the disordered phase and of four crystal structures of micelles resulting from the self-assembly of AB diblock copolymers in semi-dilute solutions. Starting from the micelle–micelle pair distribution functions determined previously in the disordered fluid phase by Monte Carlo simulations of a coarse-grained model of diblock copolymers, we extract effective pair potentials v(r) between micelle centres of mass by a novel extrapolation/inversion technique. These v(r) are used in extensive Monte Carlo simulations of micellar assemblies to determine the structures, mean-square displacements, and free energies of four ordered phases including FCC, BCC, diamond and the less common A15 crystals. For micelle densities close to melting, we predict the most stable structures to be FCC and A15, with the latter phase having the lowest free energy for micelles with small cores and large coronae, in agreement with recent predictions for micelles forming in copolymer melts [G.M. Grason et al., Phys. Rev. Lett. 91, 058304 (2003)].
Infrared Spectrum of Gaseous Methyl Radical by Rapid Scan Spectroscopy

Gaseous methyl radical was produced through flash photolysis of methyl iodide and of dimethyl mercury and a portion of its infrared spectrum was recorded (450–740 cm−1) using a rapid scan infrared spectrometer with scan rates up to 1 cm−1/μsec. Two absorptions were observed for CH3, at 607.0 and 603.3 cm−1, two for CH2D, at 561.2 and 558.0 cm−1, and one for CD3 at 460.6 cm−1, with a second possible feature at 457 cm−1. These frequencies are close to the corresponding matrix frequencies, which permits these bands to be assigned to ν2, the out‐of‐plane (umbrella) mode of CH3. The possibility that the doublets are due to inversion doubling of a pyramidal molecule is considered but evidence is presented to show that the lower frequency component is due, instead, to vibrationally excited methyl radical. The out‐of‐plane vibrational potential function is calculated assuming CH3 is planar. If the harmonic oscillator approximation is used, k2=0.174 mdyn/A but the CD3 frequency shows that the quartic contribution .
Direct Evidence for Viscosity-Independent Spreading on a Soft Solid

The kinetics of a spreading drop is usually controlled by conversion of capillary potential energy into viscous dissipation within the liquid when the solid is rigid. However, if the solid is sufficiently sot, a «wetting ridge» near the solid/liquid/vapor triple line can also be a dissipative sink as the wetting front moves. In this paper we provide evidence to show that when the substrate is soft, this local deformation near the triple line may lead to an energy dissipation that may outweigh effects due to viscosity over a large range of speeds and therefore spreading kinetics becomes viscosity independent
Electrochemical Oxidation of Gold and Thiourea in Acidic Thiourea Solutions

The dissolution of gold in acidic thiourea solutions, together with the oxidation of thioureu on gold, platinum, and glassy carbon (GC) electrodes, has been investigated using voltammetric methods. The cyclic voltammograms on platinum and GC electrodes showed a single pair of peaks for the oxidation of thiourea to formamidine disulfide and its subsequent reduction. The mechanism of the reaction is discussed. When a gold electrode was used, gold dissolution took place at a more negative potential than thiourea oxidation, with the latter reaction being shifted to a potential about 300 mV more positive than that on the platinum electrode. It was found that, at 25°C and without formamidine disulfide, gold did not dissolve when the potential was scanned rapidly. This result shows that the process of gold dissolution might include a slow surface step which can be accelerated by formamidine disulfide. It is possible that the slow surface step results from the strong adsorption of thiourea on the gold surface. The adsorption of thiourea on gold was demonstrated using the electrochemical quartz crystal microbalance.
Removal of Propylene from Fuel‐Grade Propane

Abstract Propane produced in refinery operations often contains substantial amounts of propylene. Propylene may cause problems through engine and injector deposits when propane is used as a motor fuel. Also, propylene is capable of polymerizing in storage, fuel lines, or vaporizers, and thus may cause plugging by gum deposits. As the use of propane expands into the motor fuel and other new markets, the removal of propylene will become increasingly more important. This manuscript reviews the most promising technologies for removal of propylene from refinery‐derived propane. The only current commercially‐practiced approaches are distillation and catalytic hydrogenation. Distillation is a viable technology for removal of propylene from propane, but both capital and energy costs are high, due to the very low relative volatility between the two species. Catalytic hydrogenation is straightforward, but also has a high capital cost, and the cost/availability of the continuous hydrogen production required may also be problematic. Two other approaches are very near commercialization: (1) absorption/stripping based on aqueous silver nitrate solution, and (2) pressure‐swing adsorption based on zeolite molecular sieves. Membranes also show promise to provide in a single stage separation equivalent to many stages of distillation, with simple, compact, and robust equipment. Chemically selective sorbents offer even higher degrees of separation in a single stage, albeit in more complex equipment.
Numerical Analysis of Droplet Impingement Using the Moving Particle Semi-implicit Method

Droplet impingement onto a rigid wall is simulated in two and three dimensions using the moving particle semi-implicit method. In two-dimensional calculations, the convergence is achieved and the propagation of a shockwave in a droplet is captured. The average pressure on the contact area decreases gradually after the maximum value. The numerically obtained maximum average impact pressure agrees with the Heymann correlation. A large shear stress appears at the contact edge due to jetting. A parametric study shows that the droplet diameter has only a minor effect on the pressure load dueto droplet impingement. When the impingement takes place from an impact angle of π/4 rad, the pressure load and shear stress show a dependence only on the normal velocity to the wall. A comparison between the three-dimensional and two-dimensional results shows that consideration of the three-dimensional effect can decrease the average impact pressure by about 12%.
TO EXTRACT GFC’S FROM CLASH FREE AND WELL COORDINATED REVIT MODEL

1Assistant Professor, Department of Civil Engineering, AISSMS COE, Pune, India 2,3,4,5 Research scholar, Department of Civil Department, AISSMS COE, Pune, India ---------------------------------------------------------------------***---------------------------------------------------------------------Abstract Clash detections is the process of finding where the "Clash" elements of separate models occupying the same space, or with parameters that are incompatible. Finding these inconsistencies is vital, as they would severely impact the construction process, causing delays, design changes, materials costs and a cascade of headaches and budget overruns. Clash detection was a manual process of overlaying drawings on a light table to visually see clashes a long time ago. 2D CAD operated essentially did not help in this arena . BIM tools can be used for effective and accurate clash detection for 3D digital models. Clash detection is an important and integral part of the BIM modeling process. In BIM modeling, there are several models. They are in the end integrated into a composite master model. This project is about developing Structural and Architectural 3D BIM model and using clash detection tools to detect various clashes and resolve them. These corrected models can be used to extract GFC's (Good for Construction) drawings that are used for onsite execution.
Factor Analysis of Challenges Experienced with Regard to Implementation of the Pension Act of 2011 in Malawi

This factor analysis study was undertaken to determine the underlying challenges affecting the implementation of pension Act of 2011 in Malawi. Research on challenges with regard to implementation of pension laws is very important as it reveals prevailing impending challenges so that possible solutions can be explored to address them for effective administration and management of Pension laws. The fact that Malawi has been implementing the new pension law for eight years since 2011 and has nevertheless been experiencing challenges with regard to such implementation process, studies to determine underlying (principal) implementation challenges are therefore justifiable to help generate knowledge that would be applied to develop relevant policies and regulations for effective pension management in Malawi. For this study, data were collected from 120 Malawian labour officers using a structured questionnaire with 17 challenge variables (statements). Respondents were asked to reflect on each implementing challenge statement and thus indicate their degree of agreement with each of them. A principal component factor analysis based on oblimin rotation results revealed that labour officers who took part expressed that problems of pension remittances; knowledge gaps; enforcements/compliance and economic hardships are the most current challenges facing the pension Act implementation in Malawi.
Decay resistance, extractive content, and water sorption capacity of Siberian larch (Larix sibirica Lebed.) heartwood timber

Abstract The aim of this study was to find chemical or physical properties of Siberian larch heartwood timber that correlate with the variation in decay resistance. Juvenile heartwood from 24-year-old grafts of 15 clones was exposed to three brown-rot fungi according to the standard in vitro decay test (European standard EN 113). The mass losses caused by the brown rot fungi Coniophora puteana, Poria placenta, and Gloeophyllum trabeum were 20%, 28% and 17% of the dry mass, respectively. The average mass loss over the three fungi had a strong negative correlation with the concentration of taxifolin (r=–0.673, P=0.006), as well as with the concentration of total phenolics determined by the Folin-Ciocalteu assay (r=–0.677, P=0.006). Thus, the concentration of flavonoids is a promising property for indirect measurement of the decay resistance of Siberian larch timber. The most abundant heartwood extractives, arabinogalactans, had a non-significant relationship with the decay resistance, but their concentration correlated positively with the capacity of the wood to adsorb water (r=0.736, P=0.002). The hygroscopic properties of the wood or the wood density were not associated with the decay resistance.
Simultaneous determination of methocarbamol and aspirin binary mixture in their combined tablets by derivative and ratio derivative spectrophotometry

Two simple and rapid spectrophotometric methods were developed for the simultaneous determination of methocarbamol (MET) and aspirin (ASP) in their combined dosage form. The first method, zero-crossing first derivative spectrophotometry, is based on the measurement of the first derivative amplitude values at 279.2 nm and 246.6 nm for the simultaneous determination of MET and ASP, respectively. The second method, ratio first derivative spectrophotometry, is based on the measurement of the peak amplitudes of the first derivative of the ratio spectra at 284 nm for MET and at 238.2 and 246 nm for ASP determination. The calibration graphs were linear over the range of 2.0–30.0 μg mL−1 for MET and ASP by the two proposed methods. The detection limits of the first derivative method were found to be 0.2998 and 0.3227 μg mL−1 and the quantitation limits were 0.9084 and 0.9780 μg mL−1 for MET and ASP, respectively. For the ratio first derivative method, the limits of detection and quantitation were 0.2795 and 0.8470 μg mL−1 for MET, respectively, while for ASP the limits of detection and quantitation were 0.2485 and 0.7530 μg mL−1 at 238.2 nm and 0.4173 and 1.2647 μg mL−1 at 246 nm. The proposed methods were applied successfully in the assay of the studied drugs in their combined tablets. The results compared favorably to those obtained by the reference methods.
Hitless Wavelength Selective Switch Using Vertically Coupled Microring Resonator Manipulated by Micro-Electro-Mechanical Systems Structure

Perfect hitless wavelength selective switching was demonstrated using a microring resonator. The coupling efficiency between the busline and microring was manipulated by the micro-electro-mechanical systems (MEMS) structure to eliminte the through port loss in the OFF state. The measured results of extinction ratio at the drop and through ports were 23 and 5 dB, respectively, for TE polarization at the applied voltage of 45 V. The switching loss at the through port in the OFF state was nearly 0 dB. The resonant wavelength was shifted by 0.28 nm in the OFF state and after the wavelength shift, the resonator was switched on by applying the voltage of 45 V to the MEMS structure.

Quaternized poly(phthalazinone ether ketone)s (QPPEK)s were synthesized by the chloromethylation and quaternization of poly(phthalazinone ether ketone) (PPEK) with chloromethyl methyl ether in 98% concentrated sulfuric acid and following trimethylamine. The presence of CH2Cl groups in chloromethylated PPEK was confirmed by 1H-NMR. An alkaline QPPEK membrane was prepared and its thermal and mechanical properties were tested. The alkaline QPPEK membrane had a methanol permeability 6.57 × 10−7 cm2/s and the highest anion conductivity 1.14 × 10−2 S/cm. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008
A Method for Micro-Dynamics Analysis Based on Causal Structure of Agent-Based Simulation

Micro-dynamics analysis plays an important role in decision making in a complex social system. It has been used to analyze how macro-phenomena arise from the viewpoint of individual agent behavior. However, the causes extracted during the analysis often include two types of useless causes: simple causes, which are not useful for decision making regarding new policies, and small causes, which suggest inefficient policies. In this paper, we propose a method to extract causes that include at least one feature from the "attribute," "perception," and "action" variables of model parameters and logs. We extracted the causes of the specific congestion and created a policy based on results obtained via a simulation of an airport terminal and showed that the proposed method can eliminate both simple and small causes.
Social identifications in organizational behavior

It has long been recognized that being a member of an organization can, sometimes to a significant extent, become part of how people see themselves. Such organizational identification is not without consequence. In organizational psychology and organizational behavior, the study of organizational identification took off when Ashforth and Mael (1989) proposed a conceptualization of it based on social identity theory (Tajfel & Turner, 1986). Since then, the study of social identity processes in organizations has flourished, in part because it has continued to draw on research in social psychology outside of the organizational domain (e.g., Hogg & Terry, 2000). In this chapter, we outline the development of the social identity perspective in organizational psychology and organizational behavior, noting along the way how this has been infused and continues to be infused by work in social psychology.
Covalently Attached Multilayer Assemblies by Sequential Adsorption of Polycationic Diazo-Resins and Polyanionic Poly(acrylic acid)

Diazo-resins (DAR) as polycation and poly(acrylic acid) (PAA) as polyanion were alternately assembled into a multilayer structure by using the layer-by-layer self-assembly technique. PAA as a weak polyelectrolyte was very sensitive to the pH value of the solution, and that pH could be used to tune the thickness of the PAA layer. Upon UV irradiation, a fraction of the carboxylate groups reacted with diazonium groups at the adjacent interfaces of the multialyer, so partially covalently attached multilayer assemblies could be formed. Their stability improved greatly compared with the fraction that was not UV-irradiated. The photoreaction occurring between the layers was confirmed by means of UV−visible and Fourier transform infrared spectroscopy. The thickness of the UV-irradiated films was characterized with X-ray diffraction, results from which showed that the thickness of the films can be adjusted in nanometer scale by simply changing the pH value of the solutions.
Effect of Adsorption on the Biodegradation of Nitrilotriacetate by Chelatobacter heintzii

Nitrilotriacetic acid (NTA) is a synthetic chelating agent that was used to decontaminate nuclear reactors and was disposed at Department of Energy waste sites. NTA may influence the mobility and fate of radionuclides in soils and sediments if it is not biodegraded. Because it was unclear how adsorption of NTA would influence its degradation, experiments were conducted in a model system containing gibbsite and Chelatobacter heintzii with 60CoNTA at pH 7 and NTA at pH 6 and 8. The rates of NTA desorption from gibbsite were pH dependent (desorption half-lives at pH 6, 7, and 8 were 80, 16, and 1 h, respectively, while that of Co at pH 7 was 2.5 h for equal molar CoNTA). Degradation rates of NTA in solution by C. heintzii decreased as pH decreased and depended on the dominant form of NTA in solution (e.g., biodegradation rates for HNTA2- > AlOHNTA- > CoNTA-). The degradation of NTA was significantly slower when NTA was adsorbed to gibbsite. This difference was observed at pH 6 and 8 with NTA and at pH 7 with.
STUDY OF THE ANTIFUNGAL ACTIVITY OF ORIGANUM COMPACTUM ESSENTIAL OIL AGAINST DIFFERENT PLANT PATHOGENIC FUNGI

The resistance of fungal strains to synthetic products and the search for new alternatives to them are of great importance to consumers. The main objective of this study was to identify the chemical composition of the Essential Oil (EO) of Origanum compactum and to evaluate its anti-fungal properties against four species of fungi, Fusarium culmorum, Fusarium solani, Alternaria alternata and Helminthosporium sativum. The results of gas chromatography coupled with mass spectrometry (GC-MS) revealed the presence of three major compounds in the extract, Carvacrol (72.97%), -Cymene (14.5%), and Terpinene (6.01%). Antifungal activity was tested by the microdilution method on agar medium. EOs showed potent antifungal activity against all strains of fungi tested compared to controls with minimal inhibitory concentrations (MIC) ranging from 0.02% to 0.05%. Key word: Origanum compactum, volatile extract, GC-MS, Fusarium culmorum, Fusarium solani, Alternaria alternata, and Helminthosporium sativum.
