Novel scheme to fabricate SiGe nanowires using pulsed ultraviolet laser induced epitaxy

A novel scheme is employed to fabricate SiGe nanowires in a Si(100) substrate using pulsed ultraviolet (UV) laser induced epitaxy. In particular, Si(100) substrates are patterned with arrays of Ge wires ∼60 nm in width and ∼6 nm in thickness. A thin film low temperature silicon oxide is then deposited on the substrate. SiGe nanowires with a cross section of ∼25×95 nm2 are formed using pulsed UV laser induced epitaxy. The structures are analyzed using scanning electron microscopy and cross‐sectional transmission electron microscopy. Potential applications of the wire structure include base formation in a lateral SiGe heterojunction bipolar transistor and direct formation of SiGe/Si quantum wire structures in a silicon chip.
Mo/ller–Plesset perturbation investigation of the He2 potential and the role of midbond basis functions

The Mo/ller–Plesset perturbation theory up to the complete fourth order is applied to calculate the ab initio van der Waals energy potential of He2. A scheme of constructing a very efficient basis set is proposed based on theoretical considerations. Such a basis set contains a set of Gaussian functions (usually of low angular momentum) centered at the midbond of the van der Waals molecule, which have been proven very efficient to reproduce the intersystem correlation interaction energy normally to be achieved by use of the nucleus‐centered high angular momentum polarization functions. A nuclear‐centered moderate set [5s4p2d] augmented by a set of midbond functions such as {3s3p2d} produces a value of 10.04 K for the well depth of He2 at the complete fourth‐order (MP4) theory. Results from a series of other basis sets suggest that this value is nearly saturated with the further increase of basis, which is in agreement with the estimate of the complete basis‐set limit. Calculations of the potential at the minimum and the other distances (3.0–10.0 a0) confirm that the MP4 method, together with the use of midbond functions, is a reliable and convenient choice for the accurate calculations.The Mo/ller–Plesset perturbation theory up to the complete fourth order is applied to calculate the ab initio van der Waals energy potential of He2.

Contributions of Professor Reed M. Izatt to Molecular Recognition Technology: From Laboratory to Commercial Application

Professor Reed M. Izatt has been a scientific pioneer in the discovery and development of molecular recognition technology (MRT). From early involvement in the field of macrocyclic chemistry to recent commercialization, Professor Izatt has made significant contributions to the field. Initial work focused on understanding factors important to selectivity, including cation geometry requirements, ionic radius, ligand cavity dimensions, ligand donor atom type and placement, ring number, and ring substituents. Subsequently, ligands were incorporated into useful formats including beads, membranes, and columns. Important applications were found in analytical and process industries. MRT enables the separation, recovery, and purification of specific species often from complex and difficult matrixes. Professor Izatt's scientific work has led to commercial separations including among others chloride ion, mercury, copper, lead, cesium, strontium, radium, palladium, rhodium, antimony, bismuth, gold, iron, and aluminum.
X‐ray photoelectron spectroscopy investigations of Y3Al5O12:Yb single crystal

X‐ray photoelectron spectroscopy was used to study the chemical composition and electronic structure of the Y3Al5O12:Yb (YAG:Yb) crystals. The contamination of the crystal with carbon and oxygen in the broken under UHV sample was found. The dopant concentration of Yb, in the mixed valence state, was determined as 12 %. The aluminium concentration is lower than a nominal value. The chemical shift analysis shows more ionic bond of Y‐O than Al‐O. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Investigating biogenic heterogeneity in coastal sediments with two-dimensional measurements of iron(II) and sulfide

Environmental context. Microbial respiration generally occurs in distinct layers within coastal sediment, producing high porewater iron or sulfide concentrations, although this layering is dramatically modified by the activities of sediment-dwelling organisms. The present study describes use of a new technique to simultaneously measure two-dimensional concentrations of porewater iron and sulfide at millimetre resolution, allowing the patchiness of patterns of microbial respiration in sediment to be clearly observed. The measurements generally supported a conceptual model predicting the effects of animal burrows and seagrass roots on the porewater iron and sulfide distributions, although the addition of organic matter provided some unexpected observations that require further investigation. Abstract. One of the most powerful predictive tools in sediment biogeochemistry is the electron acceptor layering model, which describes the order in which oxidised compounds are reduced by successions of respiring microbial populations, and how this layering is influenced by benthic macro-organism activity. However, techniques allowing convenient determination of heterogeneous distributions of reduced substances, such as iron(II) and sulfide, have been lacking. A combined diffusive gradients in thin films–diffusive equilibrium in thin films technique was used to quantitatively measure the two-dimensional iron(II) and sulfide distributions at high resolution in the vicinity of various sediment features, including macrofauna burrows, particulate organic matter and macrophyte roots. Substantial heterogeneity was observed for both analytes in all probes, especially in the vicinity of seagrass roots and particulate organic matter. Measured distributions tended to follow the general patterns predicted by the tertiary electron acceptor layering model. However, there was unexpected overlap of sulfide and iron(II) distributions at the millimetre to centimetre scale in several samples from different sediments, notably the more complex sediments containing particulate organic matter and seagrass roots. The cause of such overlap is unclear and further study is necessary to elucidate how such distributions can occur.
Pulse-Sequence Optimization with Analytical Derivatives. Application to Deuterium Decoupling in Oriented Phases

Abstract A pulse-sequence optimization procedure that uses a gradient-search method with analytical derivatives is demonstrated. It can be implemented for arbitrarily complex spin-system Hamiltonians and arbitrary pulse sequences. The computational method presented is time-efficient and more accurate than difference methods. It is applied to the optimization of a pulse sequence proposed by K. V. Schenker, D. Suter, and A. Pines [ J. Magn. Reson. 73, 99 (1987)] for deuterium decoupling in oriented phases. The optimized sequence is tested experimentally on pentadeuterobenzene dissolved in nematic phase.
THE EFFECTS OF EXTERNAL EXHAUST GAS RECIRCULATION AND CETANE NUMBER IMPROVER ON THE GASOLINE HOMOGENOUS CHARGE COMPRESSION IGNITION ENGINES

The influences of cold exhaust gas recirculation (EGR) and cetane number (CN) improver-di-tertiary butyl peroxide (DTBP) on the combustion characteristics and emissions of the Homogenous Charge Compression Ignition (HCCI) combustion engines fueled with PRF90 fuels (a mixture of 90% iso-octane and 10% n-heptane by volume) were studied in this paper. The experiments were performed using 0%, 1%, 2%, 3%, and 4% (by volume) DTBP-PRF90 blends. The experimental results show that the operating range was remarkably extended to lower temperature and lower engine load with the DTBP addition in PRFRON90 fuel. With the improvement of HCCI combustion at the lower temperature and light load by CN improver, the combustion phase of higher temperature and large load can be retarded to the top dead center (TDC) by appropriated EGR rate. As a result, the indicated thermal efficiency and indicated specific fuel consumption (ISFC) were improved.
Interaction of Titanium Isopropoxide with Surface Hydroxyls on Silica

Abstract Six different silicas, (two aerosils, a hydrophobic aerosil, a silica gel, and Stober spheres) pretreated at 423 K in vacuum were impregnated with Ti(Oi-Pr) 4 in a N 2 atmosphere and the excess alkoxide washed away in an inert environment. Infrared spectroscopy showed significant differences in the relative proportions of isolated and H-bonded surface hydroxyls on these silicas. The silicas that had a higher proportion of H-bonded hydroxyls picked up a greater amount of titania under our impregnation procedure. Using the route described above, the upper limit of loading appeared to be ≅3.0 Ti/nm 2 on Stober silica spheres, whose distinguishing feature was that the surface contained exclusively H-bonded hydroxyls. In situ infrared spectroscopy was also used to probe the interaction of the titanium alkoxide with the isolated as well as the H-bonded hydroxyls. On the basis of all of these experiments, we conclude that the hydroxyl groups that are capable of H-bonding with neighboring hydroxyls are the preferred adsorption sites, while the isolated hydroxyls are inert, at least at room temperature.
Calculations of electron inelastic mean free paths. III. Data for 15 inorganic compounds over the 50–2000 eV range

We report calculations of electron inelastic mean free paths (IMFPs) of 50–2000 eV electrons for a group of 14 organic compounds: 26-n-paraffin, adenine, β-carotene, bovine plasma albumin, deoxyribonucleic acid, diphenylhexatriene, guanine, kapton, polyacetylene, poly(butene-1-sulfone), polyethylene, polymethylmethacrylate, polystyrene and poly(2-vinylpyridine). The computed IMFPs for these compounds showed greater similarities in magnitude and in the dependences on electron energy than was found in our previous calculations for groups of elements and inorganic compounds (Papers II and III in this series). Comparison of the IMFPs for the organic compounds with values obtained from our predictive IMFP formula TPP-2 showed systematic differences of ∼40%. These differences are due to the extrapolation of TPP-2 from the regime of mainly high-density elements (from which it had been developed and tested) to the low-density materials such as the organic compounds. We analyzed the IMFP data for the groups of elements and organic compounds together and derived a modified empirical expression for one of the parameters in our predictive IMFP equation. The modified equation, denoted TPP-2M, is believed to be satisfactory for estimating IMFPs in elements, inorganic compounds and organic compounds.
A Study On Applications And Techniques Of Surface Re-A Study On Applications And Techniques Of Surface Re-Construction Construction

-This paper describes a general method for automatic reconstruction of accurate, concise, piecewise smooth surfaces from unorganized 3D points. Instances of surface reconstruction arise in numerous scientific and engineering applications, including reverse-engineering, the automatic generation of CAD models from physical objects etc. Previous surface reconstruction methods have typically required additional knowledge, such as structure in the data, known surface genus, or orientation information. In contrast, the method outlined in this paper requires only the 3D coordinates of the data points. From the data, the method is able to automatically infer the topological type of the surface, its geometry, and the presence and location of features such as boundaries, creases, and corners. The surface reconstruction method has three major phases: Initial surface estimation, Mesh optimization, and piecewise smooth surface optimization. In this paper emphasis has been given on the initial surface estimation.
Effect of Fiber Treatment and Fiber Loading on Mechanical Properties of Luffa-Resorcinol Composites

Tensile and compressive behaviour of resorcinol-formaldehyde (RF) matrix and its composites reinforced with fibers of Luffa cylindrica (LC) have been studied. LC fibers were subjected to chemical treatments such as alkali activation by NaOH followed by bleaching and acid hydrolysis in order to improve fiber-matrix adhesion. Both treated and untreated LC fibers are modified with calcium phosphate. The presence of hydroxy apatite, a polymorph of calcium phosphate and a major constituent of vertebrate bone and teeth, was confirmed from XRD peak of treated LC fiber. XRD analysis of the treated LC fiber has confirmed the crystalline nature of the chemically treated LC fiber by its crystallinity index. The effects of fiber loading of chemically treated and untreated LC fiber on ultimate stress, yield strength, breaking stress, and modulus of the composites were analyzed. The tensile and compressive modulus of the composites were increased with incorporation of both treated and untreated LC fibers into the RF matrix. The modulus of composites with treated LC fiber was enhanced compared to that of the untreated fiber composites. Furthermore the values of ultimate stress, yield stress, and breaking stress were increased with the incorporation of treated LC fiber in the composites.
GeomVis: WebApp for Computational Geometry Algorithm Visualization

Visualization tools hold the potential to improve the understanding of information. This potential can be extended to algorithms. Several tools already exist that take advantage of this fact. We studied existing algorithm visualization tools and identiﬁed key features for these applications, such as step-by-step execution, source code availability and support for ﬁle input and output. We also looked at the algorithms featured in these tools and identiﬁed an underrepresented class of algorithms: those from computational geometry. Namely, we ﬁnd nearly no tools for visualizing these algorithms. In this work, we present a new web-based visualization tool for computational geometry algorithms we developed, which is available online. Our application targets three main goals: to aid understanding of these algorithms via visualization; to support execution with arbitrary inputs to allow users to explore algorithm behavior freely; and to provide a modiﬁable implementation with freely available source code. We tested our application with users, and the results are promising.
Advanced Statistical Optimization of Parameters of Synthesis Process of Oxygenated Carbonated Apatite

The synthesis process of oxygenated carbonated apatite was optimized by an advanced statistical planning of experiments. Full factorial design of 24 experiments was used to find the effects of five principal parameters: pH of the reaction medium, atomic ratio Ca/P of the reagents, concentration of the calcium solution (Ca2+), temperature of the reaction medium (T) and duration of the reaction (D), with fixing the H2O2 composition at 30% and stirring to 600 turns/min. Studied responses were the atomic ratio Ca/P, % O2, % O2 2− and % CO3 2−. Optimum synthesis parameters were found to be pH = 7.38, Ca/P = 1.647, [Ca2+] = 0.636 M, T = 40°C and D = 1 h. The prediction responses were Ca/P = 1.575, % O2 = 0.76, % O2 2− = 0.50 and % CO3 2−= 1.84. The actual experimental results were in agreement with the prediction.
HPLC Analysis of Plasma Glipizide and its Application to Pharmacokinetic Study

Abstract Glipizide is an oral hypoglycemic agent widely used to treat type 2 diabetes mellitus. In this study, an efficient HPLC-UV assay method for determining the plasma glipizide level was developed, validated, and used to assess the pharmacokinetic profile of the glipizide in healthy Korean volunteers. After extraction with diethyl ether, the chromatographic separation of glipizide was carried out using a Bondclone C18 column (10 µm, 300 × 3.9 mm) with a mobile phase of 10 mM potassium phosphate monobasic and methanol (40:60 [vol/vol], pH 3.5) and UV detection at 225 nm. The flow rate of the mobile phase was 1.0 mL/min and the retention time of glipizide and internal standard (I.S.) was approximately 11.5 and 8.6 minutes, respectively. The quantification limit was 15 ng/mL and the linear range of the calibration curve ranged from 15 to 800 ng/mL in plasma with a correlation coefficient >0.9999. The mean accuracy was 86–101%. The coefficient of variation (precision) in the intra- and inter-day validation was 1.8–14.2 and 1.7–8.1%, respectively. The pharmacokinetics of oral glipizide was evaluated after administering 5 mg to each of 13 healthy Korean subjects. The AUCinf, Cmax, Tmax, and T1/2 were 3432 ± 886 ng·h/mL, 629.0 ± 94.2 ng/mL, 2.8 ± 1.8 h, and 3.9 ± 0.9 h, respectively. The results showed large inter-individual differences in the AUCinf, Cmax and T1/2.
IMPACT OF DONOR AGE ON BIOLOGICAL AND IMMUNOGENIC PROPERTIES OF MESENCHYMAL STROMAL CELLS

Over the last decades, mesenchymal stromal cells MSC have emerged as a promising therapeutic tool for cell-based therapies. However, their biological characteristics and beneficial potential may decline with patients’ age. Because most patients amenable for regenerative medicine have increased age, this could dramatically limit the autologous use of MSCs. We therefore sought to characterize the biological, immunological, and angiogenetic capacities of infant (iMSCs) versus aged MSCs (aMSCs). Both iMSCs and aMSCs showed typical spindleshaped morphology, plastic adherence, and the same potential to differentiate into osteogenic, chondrogenic and adipogenic lineages. iMSCs and aMSCs expressed MSC-typical surface markers such as CD90 and CD105 and were negative for CD45, CD34, CD31 and CD117. iMSCs showed faster in vitro proliferation (p<0.001), migration (p<0.001), and stronger endothelial adhesion (p=0.018) than aMSC. There were no differences in HLA class I, β2 microglobulin, HLA class II, and co-stimulatory molecule expression between iMSCs and aMSCs. Both immunogenic HLA class II and CD54 and tolerogenic HLA-E expression were upregulated by IFNγ. iMSCs showed significantly higher CD29 signals and stronger endothelial adhesion than aMSCs. Interestingly, iMSCs outperformed aMSCs in different angiogenesis parameters. If not used in an autologous setting, iMSCs and aMSCs similarly provoked TH1 and T H2 responses in unidirectional ELISPOT assays and donor-specific IgM antibody production. Our results thus suggest that donor age does not affect immunogenicity and immunomodulatory properties, but markedly reduces biological properties of proliferation, migration, adhesion, and limits their angiogenic effects.

Theoretical analysis of the technological process of hop drying

This article is aimed at the current questions concerning hop drying, a process which represents a significant part of energy consumption for hop producers. The water content drops during hop cone drying from the original approx. 80% of moisture to 8 or 10%. The drying medium is heated air, and the maximum drying temperatures range between 55 °C and 60 °C, remaining practically stable for the entire duration of drying. Hops are exposed to these temperatures for 6 to 8 hours. The current old and ageing belt dryers record large losses. Their modernisation and particularly new drying technologies need to derive from perfect knowledge of thermal characteristics of materials and drying devices. The drying process and the actual implementation necessarily depend on the knowledge of the entire process calculation that is why the paper introduction outlines simplified issues concerning a ‘theoretical dryer’ following the hx chart. An experimental measurement was carried out in an operating belt dryer. It included measurements of the drying medium thermal and moisture parameters and of the drying hop qualitative parameters. These drying parameters were monitored by means of continuously recording data loggers and of a laboratory analysis of the samples (hop moisture content, alpha bitter acids, Hop Storage Index). The drying process revealed that hops are practically dry (10 ± 2.0% of moisture content) already at the end of the second belt or possibly at the beginning of the third belt. It was also proven that hops are excessively dried (moisture content of 4 to 8%), adjusted to their final moisture of 8–10% through conditioning. Excessive drying results in considerate hop-cone shatter which makes the hop manipulation difficult during further processing, leading to larger losses of lupulin.
