Manganese Oxide/Graphene Aerogel Composites as an Outstanding Supercapacitor Electrode Material (2013)

Graphene aerogels (GA), prepared with an organic sol-gel process, possessing a high specific surface area of 793 m(2) g(-1) , a high pore volume of 3 cm(3) g(-1) , and a large average pore size of 17 nm, were applied as a support for manganese oxide for supercapacitor applications. The manganese oxide was electrochemically deposited into the highly porous GA to form MnO2 /GA composites. The composites, at a high manganese oxide loading of 61 wt. %, exhibited a high specific capacitance of 410 F g(-1) at 2 mV s(-1) . More importantly, the high rate specific capacitances measured at 1000 mV s(-1) for these composites were two-fold higher than those obtained with samples prepared in the absence of the GA support. The specific capacitance retention ratio, based on the specific capacitance obtained at 25 mV s(-1) , was maintained high, at 85 %, even at the high scan rate of 1000 mV s(-1) , in contrast with the significantly lower value of 67 % for the plain manganese oxide sample. For the cycling stability, the specific capacitance of the composite electrode decayed by only 5 % after 50,000 cycles at 1000 mV s(-1) . The success of this MnO2 /GA composite may be attributed to the structural advantages of high specific surface areas, high pore volumes, large pore sizes, and three-dimensionally well-connected network of the GA support. These structural advantages made possible the high mass loading of the active material, manganese oxide, large amounts of electroactive surfaces for the superficial redox events, fast mass-transfer within the porous structure, and well-connected conductive paths for the involved charge transport.
Getting Started (2018)

One of the main goals of JPA was that it should be simple to use and easy to understand. Although its problem domain cannot be trivialized or watered down, the technology that enables developers to deal with it can be straightforward and intuitive. This chapter shows how effortless it can be to develop and use entities.
Esophagus histological analysis after hyperthermia-induced injury: Implications for cardiac ablation (2009)

Hyperthermic treatment mainly affects the epithelium and deeper muscular layers. The results suggest a damage threshold of 50 degrees C for treatments of 30-90 s. The proposed scoring system provides a good fit with the hyperthermic parameters.
Ein Sieg für das Redaktionsgeheimnis (2020)

Der Europäische Gerichtshof für Menschenrechte rügt in einem Kammerentscheid einstimmig die Schweiz: Sie habe Art. 10 EMRK verletzt, indem einer Journalistin die Berufung auf das Redaktionsgeheimnis versagt worden war und sie zur Zeugenaussage verpflichtet wurde. Das Bundesgericht hatte – entgegen dem Basler Appellationsgericht – im beschriebenen Drogenhandel eine «Katalogtat» im Sinne von Art. 172 Abs. 2 lit. b StPO gesehen und deshalb den Antrag der Staatsanwaltschaft gestützt. Diese wollte von der Journalistin den Namen eines von ihr in einem Zeitungsartikel porträtierten Drogenhändlers. Der EGMR befand dagegen, dass in jedem Einzelfall konkret eine Interessenabwägung vorgenommen und geprüft werden müsse, ob das öffentliche Interesse eine Aufhebung des Redaktionsgeheimnisses gebiete. Das wurde vorliegend verneint, womit ein Verstoss gegen die EMRK vorliegt.
Coupled Adsorption/Precipitation Of Scale Inhibitors: Experimental Results And Modelling (2008)

Abstract In this paper, results are presented on the general mechanisms by which scale inhibitors (SIs) are retained within porous media. There is a generally accepted view that the main two mechanisms of SI retention are "adsorption" and "precipitation" and these are described by different but related modelling approaches in the literature. These approaches have been used quite successfully to model field squeeze treatments. To analyse in a detailed and unambiguous manner where a given retention mechanism (e.g. pure adsorption) or mechanisms (e.g. coupled adsorption and precipitation) are operating requires that we carry out careful laboratory experiments under "field relevant" conditions. In this work, we study adsorption vs. adsorption/ precipitation by performing a series of experiments where we know that the system exhibits either (a) adsorption only or (b) coupled adsorption/precipitation. Experimentally it is straightforward to determine which regime the system is in, as explained below. We present the theory describing the coupled adsorption/precipitation process. In addition, an extensive series of experimental adsorption/precipitation measurements are presented for various mineral separates including sand, chlorite, siderite, muscovite, kaolinite, feldspar and montmorillonite. The coupled adsorption/ precipitation model is in very good agreement with experiment.
Chromic acid anodized Ti-6Al-4V: its characterization and its single lap bond strength to heat resistant adhesives (1987)

Anodized Ti-6Al-HV/adhesive bonds exhibit improved corrosion resistance and a higher strength-to-weight ratio compared to conventional metal bonding techniques for primary and/or secondary structural applications. This work was conducted to identify chromic acid (CA) anodization and bond process conditions which produced durable, structural anodized Ti-6Al-4V/heat resistant single lap bonds and to understand why these conditions were necessary. A structural single lap bond was defined as a bond tested at 298K ≤ 0.5 month after bonding and with a strength ≥ 6.9 MPa, based upon values reported in structural adhesive manufacturers' product literature. A durable, structural single lap bond was defined as a bond with a strength ≥ 6.9 MPa strength at 298K after 9 months aging at 433K. Heat resistant adhesives tested had reported service temperatures ≥ 423K, and were: polysulfone; eolyethersulfone; polyphenylquinoxaline; polyetherimide, both unfilled and 20% glass filled; and 50% calcium carbonate filled polyimide. Hydrofluoric acid (HF) added to the CA anodization solution was necessary to produce structural bonds. CA/HF oxide was more porous, and thicker than the CA anodic oxide (140 nm vs. 20 nm), perhaps promoting physical and oxide/adhesive interphase mechanical interlock. Structural, durable CA/HF anodized Ti-6Al-4V-adhesive bonds were produced for all adhesives tested except for the filled polyimide (5.5 MPa). The filler may have occluded oxide pores and prevented optimal adhesive/oxide interphase interlock, and there may have been competition of polyimide for calcium carbonate filler and for oxide. Average oxide thickness values of 65 to 410 nm did not affect bond strength; structural bonds were produced in all cases. CA/HF initial current density of 20 Amperes per square meter produced 33% stronger polysulfone bonds than 30 Amperes per square meter. Polysulfone microstructure may have been chemically degraded by the unnecessarily high fluoride concentration in the oxide from the higher current density. Lica® 44 titanate primer did not significantly influence bond strength or durability, except when unfilled polyetherimide was the adhesive. Polyphenylquinoxaline bond processing influenced bond strength. Structural bonds resulted for all the CA/HF anodization and process conditions described above. Single Iap bond fracture initiated in the adhesive (polymer) fillet. Fracture propagation in the bond overlap was through the polymer/anodic oxide interphase and/or cohesively in the polymer.

Pyrolysis of Mesoporous Silica-Immobilized 1,3-Diphenylpropane. Impact of Pore Confinement and Size (2005)

Mesoporous silicas such as SBA-15 and MCM-41 are being actively investigated for potential applications in catalysis, separations, and synthesis of nanostructured materials. A new method for functionalizing these mesoporous silicas with aromatic phenols is described. The resulting novel hybrid materials possess silyl aryl ether linkages to the silica surface that are thermally stable to ca. 550 degrees C, but can be easily cleaved at room temperature with aqueous base for quantitative recovery of the organic moieties. The materials have been characterized by nitrogen physisorption, FTIR, NMR, and quantitative analysis of surface coverages. The maximum densities of 1,3-diphenylpropane (DPP) molecules that could be grafted to the surface were less than those measured on a nonporous, fumed silica (Cabosil) and were also found to decrease as a function of decreasing pore size (5.6-1.7 nm). This is a consequence of steric congestion in the pores that is magnified at the smaller pore sizes, consistent with parallel studies conducted using a conventional silylating reagent, 1,1,3,3-tetramethyldisilazane. Pyrolysis of the silica-immobilized DPP revealed that pore confinement leads to enhanced rates and altered product selectivity for this free-radical reaction compared with the nonporous silica, and the rates and selectivities also depended on pore size. The influence of confinement is discussed in terms of enhanced encounter frequencies for bimolecular reaction steps and pore surface curvature that alters the accessibility and resultant selectivity for hydrogen transfer steps.
A Highly Photostable Near‐Infrared Labeling Agent Based on a Phospha‐rhodamine for Long‐Term and Deep Imaging (2018)

Various fluorescence microscopy techniques require bright NIR-emitting fluorophores with high chemical and photostability. Now, the significant performance improvement of phosphorus-substituted rhodamine dyes (PORs) upon substitution at the 9-position with a 2,6-dimethoxyphenyl group is reported. The thus obtained dye PREX 710 was used to stain mitochondria in living cells, which allowed long-term and three-color imaging in the vis-NIR range. Moreover, the high fluorescence longevity of PREX 710 allows tracking a dye-labeled biomolecule by single-molecule microscopy under physiological conditions. Deep imaging of blood vessels in mice brain has also been achieved using the bright NIR-emitting PREX 710-dextran conjugate.
FastGCN: Fast Learning with Graph Convolutional Networks via Importance Sampling (2018)

The graph convolutional networks (GCN) recently proposed by Kipf and Welling are an effective graph model for semi-supervised learning. This model, however, was originally designed to be learned with the presence of both training and test data. Moreover, the recursive neighborhood expansion across layers poses time and memory challenges for training with large, dense graphs. To relax the requirement of simultaneous availability of test data, we interpret graph convolutions as integral transforms of embedding functions under probability measures. Such an interpretation allows for the use of Monte Carlo approaches to consistently estimate the integrals, which in turn leads to a batched training scheme as we propose in this work---FastGCN. Enhanced with importance sampling, FastGCN not only is efficient for training but also generalizes well for inference. We show a comprehensive set of experiments to demonstrate its effectiveness compared with GCN and related models. In particular, training is orders of magnitude more efficient while predictions remain comparably accurate.

Involvement of Hgs/Hrs in Signaling for Cytokine-mediated c-fos Induction through Interaction with TAK1 and Pak1 (2001)

Hgs/Hrs is a tyrosine-phosphorylated FYVE finger protein that is induced by stimulation with various cytokines and growth factors. Here we show that Hgs plays critical roles in the signaling pathway for the interleukin-2-induced activation of the serum-response element and cyclic AMP-response element of the c-fos promoter. We found that Hgs associated physically with transforming growth factor-beta-activated kinase 1 (TAK1) and p21-activated kinase 1 (Pak1), which mediate the activation of c-Jun N-terminal kinase and serum response factor, respectively, leading to transactivation via the serum-response element and cyclic AMP-response element. These results suggest that Hgs is involved in the TAK1-JNK and Pak1-serum response factor pathways for the c-fos induction that is initiated by cytokines.
A Non-volatile Analog Storage Device Using EEPROM Technology (1991)

Conventional storage of analog waveforms requires converting the signal to digital form, storing in digital memory and then converting retrieved data to analog form. This paper describes an integrated circuit which stores non-volatile analog voltages, eliminating data conversion and resulting in a significant increase in storage density compared to that achieved by digital techniques.
Stability of epitaxial BiXO3 phases by density-functional theory (2020)

The bismuth-based perovskites are an interesting class of materials that exhibit a variety of coupled ferroic properties. Through epitaxial growth in the (001) pseudo-cubic [(001)pc] orientation, various phases with variable ferroelectric polarization can be stabilized. Using density-functional theory calculations, we predict the phase stability of the bismuth-based perovskite oxides as a function of pseudo-cubic in-plane (IP) lattice constant, mimicking (001)pc epitaxial films. We find that the BiMnO3, BiCoO3, and BiNiO3 systems each exhibit only one stable phase over a wide range of IP lattice constants. In the BiFeO3 (BFO) and BiCrO3 (BCO) systems, by comparison, we find several phases that are energetically favorable, depending on the value of the IP strain. The BFO phases predicted to be stable, in order of increasing compressive IP strain, are monoclinic Cc, triclinic P1, monoclinic Cm, and tetragonal P4mm. In the BCO system, we find two orthorhombic Pbnm phases, respectively, under no IP strain and under compressive IP strain, and one monoclinic Cc phase to be stable under tensile IP strain. Our results serve to guide experimental efforts in terms of selecting growth substrates with the goal of achieving desired epitaxial-stabilized perovskite phases and to support future investigations of the tunability of BXO properties with epitaxial strain.
In Vitro Studies of a Novel Antimicrobial Luer‐Activated Needleless Connector for Prevention of Catheter‐Related Bloodstream Infection (2010)

These simulation experiments show that needleless connectors readily acquire an internal biofilm when microorganisms gain access to the internal fluid path and that biofilm formation allows an exponential buildup of internal contamination, with shedding back into the fluid path and downstream sufficient to cause bacteremia. Incorporation of nanoparticle silver into the lining surfaces of the novel connector kills microorganisms in the fluid pathway and prevents internal biofilm formation, even with high levels of introduced contamination and continuous fluid flow. This technology deserves to be evaluated in a prospective, randomized clinical trial to determine its capacity to prevent catheter-associated bloodstream infection.
Preparation, <sup>1</sup>H and <sup>13</sup>C NMR, and ab initio/IGLO study of mono-<i>O</i>-protonated deltic acid and theoretical investigation of di-, tri-, and tetra-<i>O</i>-protonated deltic acids (1999)

The hitherto elusive mono-O-protonated deltic acid C3O3H3+ was prepared by protolysis of di-tert-butoxy deltate in FSO3H-SO2ClF and in FSO3H:SbF5 (Magic Acid; 1:1 molar solution) in SO2ClF as solvent at -78°C and was characterized by 1H and 13C NMR spectroscopy. The structure and NMR chemical shifts were also calculated by the ab initio/IGLO method. No NMR evidence was found for persistent di-O-protonated deltic acid under these conditions, although a limited equilibrium with the mono-O-protonated species can be involved. Di-, tri-, and tetra-O-protonated deltic acids were also studied by ab initio/IGLO method.Key words: protonated deltic acid, aromaticity, superacids, NMR spectroscopy, ab initio and IGLO calculations.
Low-input Modified Extensive Shrimp Culture Systems for <i>Penaeus monodon</i> Restrain Vibriosis (2013)

It was hypothesized that an outbreak of vibriosis can be restrained in ponds with a low stocking density (~5 post-larvae m -2 ) till harvest. Therefore, during a 135 day production cycle of Penaeus monodon at an aquaculture facility, we monitored (i) physico-chemical parameters (ii) abundance of total heterotrophic bacteria (THB), total Vibrio like organisms (TVLO) and luminescent bacteria (LB) (iii) alterations in environmental factors controlling Vibrio abundance and (iv) changes in composition of the Vibrio community. Physico-chemical parameters were within the optimum range recommended for culture of P. monodon . In source and pond water, THB abundance remained steady at 10 3 CFU mL -1 throughout the culture period whereas in sediments, they varied between 10 2-4 CFU g -1 . The abundance of TVLO and LB in pond components were below the threshold levels of 10 4 CFU mL -1 and 10 2 CFU mL -1 respectively. THB, TVLO and LB were more abundant in the shrimp hepatopancreas (10 5 CFU g -1 ) yet apparently below the threshold for the outbreak of vibriosis in the current set up. Changes in bacterial abundance were seemingly independent of changes in environmental parameters suggesting that the systems maintained TVLO below disease-causing threshold. The Vibrio community was represented mainly by V. metschnikovii , V. fluvialis , V. mimicu s and the closely related  Aeromonas spp.. The vibrios in shrimp hepatopancreas were similar to other pond components with no dominance of particular species. A disease-free environment prevailed and shrimp yield was sustainable within the set framework perhaps due to the low abundance of vibrios represented by innocuous strains.

Caracterización geoquímica y petrográfica de las unidades geológicas del macizo del volcán Poás, Costa Rica (2009)

En este estudio definimos la estratigrafía del volcán Poás con base en la geología, petrografía, geocronología y geoquímica de sus unidades. El sector norte está constituido por las unidades Río Sarapiquí, Andesitas La Paz, Formación Tiribí (del volcán Barva, pero interdigitada), Lavas Río Cuarto, Von Frantzius, Cerro Congo, Bosque Alegre y Laguna Kopper. El sector sur está constituido por la Formación Colima, Unidad Andesitas La Paz, Formación Tiribí y las unidades Achiote, Poasito, Sabana Redonda y la Toba de Lapilli Poás. Mientras que el sector central está conformado por la unidad Cima del Poás que incluye los productos de los cráteres Principal y Botos. Las rocas de estas unidades varían desde basaltos hasta dacitas y se pueden correlacionar geoquímicamente con los componentes magmáticos del Poás: 1) Componente Geoquímico Sabana Redonda, con valores de TiO2 &gt; 1%, y enriquecido en HFSE y trazas, presente en las unidades Andesitas La Paz, Lavas Río Cuarto, Poasito, Sabana Redonda, la Toba de Lapilli Poás y algunas lavas del cráter Botos. 2) Componente Geoquímico Von Frantzius con valores de TiO2 &lt; 0,8 %, presente en las lavas de la zona del cráter Principal, Von Frantzius, las Unidades Achiote, Bosque Alegre, Cerro Congo y algunas lavas del cráter Botos. Durante los últimos 600 ka el contenido de K2O y otros elementos mayores como TiO2 y P2O5, y las trazas Zr, Ba han variado significativamente a través del tiempo en estas unidades, evidenciando la presencia de estos dos componentes desde los inicios de la actividad magmática del Poás. En rangos de tiempo similares estos dos componentes geoquímicos han coexistido, como es el caso de las lavas de los cráteres Botos y Principal. En unidades con un centro de emisión similar como Andesitas la Paz, Achiote y Cráter Principal, el contenido de K2O y TiO2 ha disminuido a través del tiempo. Sin embargo, más datos geocronológicos son necesarios para mejorar estas interpretaciones.
Novel Organic-Inorganic Hybrid Compounds Containing Alkyldiammonium Salts (2002)

Novel organic-inorganic hybrid compounds, C n N 2 PbBr 4 (n=4,6,8 and 10) and C 2 N 2 PbBr 4 · DMSO, were prepared by the self-organization of lead bromide and a variety of alkyldiammonium cations. The powder X-ray diffraction patterns of C n N 2 PbBr 4 demonstrated that the compounds form layered perovskite structures and the interlayer spacing are dependent on the length of alkyl chain. The absorption and fluorescence spectra of C n N 2 PbBr 4 and C 2 N 2 PbBr 4 · DMSO crystalline powder showed an excitonic absorption peak at around 390 nm, which suggests that the formation of two-dimensional inorganic sheets and quantum confinement structure.
