DEVELOPMENT OF A LIQUID CHROMATOGRAPHY-TANDEM MASS SPECTROMETRY METHOD FOR THE DETERMINATION OF INDIRUBIN-5-NITRO-3′-MONOXIME, A NOVEL CDK INHIBITOR, IN RAT PLASMA

A simple and rapid liquid chromatography-tandem mass spectrometry (LC–MS/MS) method has been developed and validated for the quantitation of indirubin-5-nitro-3′-monoxime (5-NIO) in rat plasma using 5-chloro-5′-chloro-indirubinoxime as the internal standard. The sample preparation involved protein precipitation using acetonitrile. Separation was achieved on an Xterra column C18 (2.1 mm × 50 mm, i.d. 5 µm) using a mixture of 0.1% formic acid-water/acetonitrile (18:82, v/v) as the mobile phase at a flow rate of 300 µL/min. Quantitation was performed on a triple quadrupole mass spectrometer employing electrospray ionization and multiple reaction monitoring (MRM) in negative ion mode. The total chromatographic run time was 2.5 min, and the calibration curves of 5-NIO were linear (correlation coefficient range: 0.9989–0.9999) over the concentration range of 0.2–2000 ng/mL in rat plasma. Also, the detection limit of the method was 0.05 ng/mL and it showed good accuracy and precision within the concentration range of 0.45–376 ng/mL. This validated method was successfully applied to estimating the pharmacokinetic parameters of 5-NIO following intravenous administration of 5-NIO to rats.

Thin Films of Copper Oxide and Copper Grown by Atomic Layer Deposition for Applications in Metallization Systems of Microelectronic Devices

Copper-based multi-level metallization systems in today’s ultralarge-scale integrated electronic circuits require the fabrication of diffusion barriers and conductive seed layers for the electrochemical metal deposition. Such films of only several nanometers in thickness have to be deposited void-free and conformal in patterned dielectrics. The envisaged further reduction of the geometric dimensions of the interconnect system calls for coating techniques that circumvent the drawbacks of the well-established physical vapor deposition. The atomic layer deposition method (ALD) allows depositing films on the nanometer scale conformally both on three-dimensional objects as well as on large-area substrates. The present work therefore is concerned with the development of an ALD process to grow copper oxide films based on the metal-organic precursor bis(trin-butylphosphane)copper(I)acetylacetonate [(Bu3P)2Cu(acac)]. This liquid, non-fluorinated βdiketonate is brought to react with a mixture of water vapor and oxygen at temperatures from 100 to 160°C. Typical ALD-like growth behavior arises between 100 and 130°C, depending on the respective substrate used. On tantalum nitride and silicon dioxide substrates, smooth films and selfsaturating film growth, typical for ALD, are obtained. On ruthenium substrates, positive deposition results are obtained as well. However, a considerable intermixing of the ALD copper oxide with the underlying films takes place. Tantalum substrates lead to a fast self-decomposition of the copper precursor. As a consequence, isolated nuclei or larger particles are always obtained together with continuous films. The copper oxide films grown by ALD can be reduced to copper by vapor-phase processes. If formic acid is used as the reducing agent, these processes can already be carried out at similar temperatures as the ALD, so that agglomeration of the films is largely avoided. Also for an integration with subsequent electrochemical copper deposition, the combination of ALD copper and ruthenium proves advantageous, especially with respect to the quality of the electroplated films and their filling behavior in interconnect structures. Furthermore, the ALD process developed also bears potential for an integration with carbon nanotubes.
One‐Step Exfoliation and Hydroxylation of Boron Nitride Nanosheets with Enhanced Optical Limiting Performance

Hexagonal boron nitride (h‐BN) nanosheets are attracting increased attention because of their excellent optical properties. Inspired by the natural exfoliation of seaside rocks, we propose a “chemical weathering” concept for fabricating h‐BN nanosheets from their bulk counterparts. We experimentally demonstrate that chemical weathering‐assisted exfoliation is a simple and efficient method for preparing h‐BN nanosheets. These nanolayers have a high solubility in water because of the hydroxylation of h‐BN (OH‐BNNS). Interestingly, the as‐prepared OH‐BNNSs exhibit excellent optical limiting properties with fascinating two‐photon absorption. It is a new and advanced optical material in the application of sensitive optical components, and shield human eyes from laser‐induced damage.
CINÉTICA DE SECAGEM DE GRÃOS DE ABÓBORA

The objective this work was to study the drying of integers grains of pumpkin, grains without tegument and grain flour of pumpkin in an oven with forced air circulation at temperatures of 40, 50, 60, 70 and 80 °C and adjust the mathematical models of the Diffusion Approximation, Two Term Exponential, Hen- derson and Pabis, Logarithmic and Page, to the experimental values. The fit of the mathematical models to data from the drying kinetics was performed using analysis of nonlinear regression, through Quasi-Newton method, using the software Statistica 5.0. As a criterion for adjustment of the models the coefficient of determination and mean-square deviation were used. It was observed that processing influenced the time of drying, where the samples of grain flour of pumpkin demanded a shortest time to reach equilibrium. For samples of integers grains of pumpkin and grains without tegument, the model that best fitted the experimental data was of the Dif- fusion Approximation at all temperatures studied; for samples of grain flour, the logarithmic model was the best fit to drying curve.
Spin dynamics of YbRh2Si2 observed by electron spin resonance

Below the Kondo temperature TK, electron spin resonance (ESR) usually is not observable from the Kondo ion itself because the characteristic spin fluctuation energy results in a huge width of the ESR line. The heavy-fermion metal YbRh2Si2 seems to be an exceptional case in which definite ESR spectra show characteristic properties of the Kondo ion Yb3+ well below TK. We found that the spin dynamics of YbRh2Si2, as determined by its ESR relaxation, is spatially characterized by an anisotropy of the zero-temperature residual relaxation only.
Removing Trihalomethanes by Packed-Column and Diffused Aeration

The performance of packed-column and diffused aeration for removing trihalomethanes from drinking water was related to water source, water temperature, contaminant concentration, and other process variables. Data obtained from this study were compared with theoretical predictions and with the results of previous feasibility studies. Based on efficiency and cost, packed-column aeration appears to be the more promising of the two technologies.
Study of poly(itaconic acid) in aqueous solutions

Poly(itaconic acid) (PIA) have been synthesized by hydrolysis of poly(itaconic anhydride) and by polymerization of itaconic acid initiated by redox system. Conductometric, potentiometric and spectrophotometric titration of aqueous solutions of PIA have been carried out. The results are discussed in terms of a conformational transition. Apparent dissociation constant and conductance of PIA solutions have been investigated as functions of concentration.
Coupled Marangoni-Benard/Rayleigh-Benard Instability with Temperature Dependent Viscosity

The onset of convection induced by coupled surface tension gradient and buoyancy forces is investigated with temperature dependent viscosity. Both surface tension and viscosity are assumed to vary linearly with temperature. The limiting case, Ma=0, is the buoyancy driven convection problem typically referred to as the Rayleigh-Benard stability problem. The other limiting case, Ra=0, is the surface tension (gradient) driven flow problem referred to as the Marangoni-Benard problem. The equations and boundary conditions obtained from the linear analysis are solved numerically as a generalized eigenvalue problem. Neutral stability curves for different viscosity slopes have been generated for the Marangoni-Benard and Rayleigh-Benard problems. It is shown that the curves can be collapsed to a single curve by appropriately scaling the results for each of the limiting cases. The critical Marangoni number is determined as a function of the slope of the viscosity temperature variation, epsilon, for different values of the Rayleigh number. When the viscosity decreases linearly with temperature, the coupled buoyancy-surface tension problem, including the limiting cases of Ra=0 and Ma=0, is found to be more stable than the constant viscosity case.
Current capabilities of “HPTAM” for modeling high-temperature heat pipes’ startup from a frozen state

The Heat Pipe Transient Analysis Model “HPTAM” has been developed at the University of New Mexico’s Institute for Space and Nuclear Power Studies for simulating the transient and steady state operation as well as the startup of alkali-metal and low-temperature heat pipes from a frozen state. This model has been subject to continuous upgrade and verification since the early nineties using experimental data for water, sodium, and lithium heat pipes. Some of the current capabilities of HPTAM include tracking: (a) the progression of the 2-D thaw front in the wick and the transition fronts separating the successive flow regimes (free-molecular, transition, and continuum) in the vapor core; (b) the liquid circulation in the wick and in the annular space that may be incorporated by design between the wick and the heat pipe wall; (c) the formation of the wet point at the wick-vapor interface and its progression toward the condenser; (d) the excess liquid volume resulting from the decrease in density of the workin.
Modeling short pulse duration shock initiation of solid explosives

The chemical reaction rate law in the ignition and growth model of shock initiation and detonation of solid explosives is modified so that the model can accurately simulate short pulse duration shock initiation. The reaction rate law contains three terms to model the ignition of hot spots by shock compression, the slow growth of reaction from these isolated hot spots, and the rapid completion of reaction as the hot spots coalesce. Comparisons for PBX 9404 between calculated and experimental records are presented for the electric gun mylar flyer plate system, the minimum priming charge test, embedded manganin pressure and particle velocity gauges, and VISAR particle velocity measurements for a wide variety of input pressures, rise times and pulse durations. The ignition and growth model is now a fully developed phenomenological tool that can be applied with confidence to almost any hazard, vulnerability or explosive performance problem. 27 refs., 16 figs., 2 tabs.
By-Products From Jumbo Squid (Dosidicus gigas): A New Source of Collagen Bio-Plasticizer?

The principal by-products that result from the catch and processing of seafood include viscera, heads, cut-offs, bone, and skin. Therefore, a large and considerable volume of solid waste is obtained, constituting an important source of environmental contaminants unless efforts for their recovery are attained (Arvanitoyannis & Kassaveti, 2008). In the case of squid, one the largest known mollusks, the global capture represents no more than 2% of the total catch. However, by-products from squid processing, which include heads, viscera, backbones or pens, ink, skin, unclaimed fins, mantles, and tentacles, may represent up to 60% of the whole weight. In addition, from all the different anatomical squid components regarded as by-products only the beak and pen are not edible. Thus, since most of the squid is not used, its by-products also pose an environmental issue for this fishery, especially in areas where it is harvested the most. The valuable and profitable components that these byproducts contain include among others chitin, chitosan, collagen, and gelatin (Kim & Mendis, 2006; Shahidi, 2006).
Continuum Solvent Modeling of Nonpolar Solvation: Improvement by Separating Surface Area Dependent Cavity and Dispersion Contributions

Continuum models are frequently used to calculate hydration properties of organic and biomolecules and to estimate its dependence on conformation and association. Often a single surface tension parameter has been used to estimate nonpolar solvation contributions from the solvent accessible surface of a molecule. The assumption of a uniform surface tension parameter is based on the observation that for linear alkanes free energies of hydration (vacuum to water transfer free energies) increase (approximately) linearly with the solvent accessible surface area (SAS). However, this correlation for example does not hold for the vacuum to water transfer of cyclic alkanes. The transfer of a nonpolar solute from vacuum to water can be formally split into a contribution due to cavity formation which involves a redistribution and reordering of water molecules and changes in water−water interaction and second van der Waals (dispersion) interactions between solute and water. In the present study, the solute solvent di.

Removal of Tar Model Compounds Produced from Biomass Gasification Using Activated Carbons

Dry gas cleaning was performed using five different commercial activated carbons (ACs) at 150-300°C. Phenol, o-cresol, naphthalene, and 1-methylnaphthalene were employed as the tar model compounds that produced from biomass gasification. The effect of the adsorption temperature and physical characteristics of ACs on the adsorption behaviors such as the breakthrough curves and adsorption capacities was investigated using a fixed-bed reactor. At 150°C, o-cresol and naphthalene were effectively removed; the adsorption capacities of the ACs were 13.4-19.4g-tar/(100g-AC) and 19.9-23.7g-tar/(100g-AC) in o-cresol and naphthalene, respectively. For effective tar removal, a larger surface area, a smaller average particle size, and an appropriate pore diameter were necessary. The effect of the tar model compounds on the adsorption behavior was investigated using the same AC at 150°C. The adsorption capacity was found to be 10.5-32.6g-tar/(100g-AC) in the following order : phenol<o-cresol<naphthalene<1-methylnaphthalene. Tar compounds having methyl groups (o-cresol and 1-methylnaphthalene) were removed more effectively as compared to those having no methyl groups (phenol and naphthalene).
Clathrate‐hydrate film growth along water/methane phase boundaries—an observational study

Methane hydrate films, each growing along a horizontal interface between the quiescent liquid‐water and methane‐gas phases, were observed through a low magnification microscope to reveal the morphology and advancing motion of the film front, and the linear film growth rate (advancing speed of the film front) at various degrees of system subcooling from the phase‐equilibrium temperature corresponding to the system pressure was quantitatively measured. At a lower subcooling (≈ 1.2 K), the film front was often covered by laterally aligned facets showing a regular roughness with sharp peaks and valleys and a non‐isotropic growth. As the subcooling increased, the film front tended to have an irregular, non‐faceted, smaller‐scale roughness and exhibited a smoother, isotropic growth. For such an isotropic, quasi‐steady film growth at subcoolings from ∼2.5 to ∼10 K, we collected the film‐growth rate data. The obtained data were compared to other relevant data or empirical correlations previously reported by different research groups. The consistency or inconsistency between the different data sources were examined in detail.
OPUS‐Ca: A knowledge‐based potential function requiring only Cα positions

In this paper, we report a knowledge‐based potential function, named the OPUS‐Ca potential, that requires only Cα positions as input. The contributions from other atomic positions were established from pseudo‐positions artificially built from a Cα trace for auxiliary purposes. The potential function is formed based on seven major representative molecular interactions in proteins: distance‐dependent pairwise energy with orientational preference, hydrogen bonding energy, short‐range energy, packing energy, tri‐peptide packing energy, three‐body energy, and solvation energy. From the testing of decoy recognition on a number of commonly used decoy sets, it is shown that the new potential function outperforms all known Cα‐based potentials and most other coarse‐grained ones that require more information than Cα positions. We hope that this potential function adds a new tool for protein structural modeling.

The effect of individual milk proteins on bioaccessibility of green tea flavan‐3‐ols (1044.12)

While information regarding impact of flavan‐3‐ol‐protein interactions on food quality exists, the ability of these interactions to alter bioavailability of health promoting flavan‐3‐ols remains unclear. The objectives of this study were to characterize influence of milk proteins and matrix on in vitro bioaccessibility of flavan‐3‐ols and to assess impact of protein digestion on protein‐flavan‐3‐ol binding. Protein solutions containing sodium‐caseinate (S‐CSN), α‐lactalbumin (α‐LA), β‐lactoglobulin (β‐LG), or non‐fat dry milk (NFDM) were prepared in Jenness Koops (JK) buffer containing milk salts and formulated at 10‐40% (v/v) into green tea beverages containing 0.6 mg/mL total flavan‐3‐ols. Samples were subjected to a three‐stage in vitro digestion to assess flavan‐3‐ol stability and bioaccessibility. Milk protein, most notably S‐CSN, significantly decreased (p<0.05) bioaccessibility of flavan‐3‐ols relative to JK buffer controls (10 relative to 32%). Interestingly, milk minerals significantly increased (p<0.05) flavan‐3‐ol bioaccessibility compared to water formulated controls (32 relative to 18%). Data from in vitro digestions combined with SDS‐PAGE and fluorometric analyses suggest that both milk proteins and minerals may alter flavan‐3‐ol bioaccessibility but normal intestinal digestion likely minimizes the impact of protein interactions.
Tear Film Dynamics Concerning A Lipid Reservoir

We investigate the dynamics of the human multilayer tear film, subject to a reservoir of lipid at the lids. A numerical method is constructed to solve a one-dimensional tear film model, derived using lubrication theory. Three choices for the open eye boundary conditions are explored including a specified lipid to mimic a lipid reservoir, a no lipid flux boundary condition to conserve lipid initially present in the system, and finally mixed lipid flux boundary condition which to our knowledge, has not been previously studied. For the blinking eye, we choose to use no diffusive flux for the lipid boundary condition.
Decay Rate Kinetics of Ozone Gas in Rice Grains

The present study was carried out to evaluate the effects of ozone on rice grains for the following three conditions: saturation time, decay rate, and half-life of ozone. Experiments were performed in different bed thicknesses (5 and 10 cm) and moisture content (11.4 and 14.2% wb) at atmospheric conditions. The lowest saturation time of ozone was 119 min, with the concentration of 516 ppm for rice grains ozonated at 5-cm bed thickness with 11.4% (wb) moisture content. The decay rate kinetics of ozone obtained were consistent with a first-order model. Regarding the half-life of ozone, the lowest value obtained was 6.78 min for rice grains ozonated at 10-cm bed thickness with 14.2% (wb) moisture content.
