These complexes form tridentate orthopalladated species upon heating in the presence or sodium acetate. The reverse reaction occurs upon addition of HCl center dot Et2O. The rate of orthopalladation and reprotonation is highly dependent on the steric bulk of the ligand. Related cationic species were also synthesized and characterized and found to be inert in the presence of 1-hexene and styrene.},

	abstract = {The question of whether a vapour-liquid phase transition exists in systems of particles with purely dipolar interactions is examined. New Monte Carlo simulation results are presented for the dipolar Yukawa hard sphere (DYHS) fluid with very small values of the attractive Yukawa well depth, almost two orders of magnitude smaller than the characteristic dipolar interaction energy. In this way, it is possible to approach the dipolar hard sphere (DHS) limit. It is found that phase separation is not observable beyond a critical value of the Yukawa energy parameter, even though in thermodynamic and structural terms, the DYHS and DHS systems are very similar. It is suggested that either some very subtle physics distinguishes the DYHS and DHS systems, or the observation of a phase transition in DHSs is precluded by finite-size effects.},

	abstract = {The specific binding characteristics of alpha(v)beta(3) integrins with an arginine-glycine-aspartic-acid (RGD) containing fluorescently labeled cyclic peptide is investigated with capillary electrophoresis-frontal analysis method. The new algorithm used to calculate the binding constants and binding stoichiometry was derived without the assumptions made in the commonly used Scatchard Plot method, thus enabling the determination of specific binding parameters in the presence of nonspecific binding. The a,6,3 integrin, a membrane protein, was studied in solution, without the need of immobilization or any other kind of modification. An RGD containing fluorescently labeled cyclic pentapeptide is used as the ligand with both specific and nonspecific binding characteristics, and an arginine-alanine-aspartic-acid (RAD) containing peptide is used as the control for nonspecific binding. While a typical specific binding isotherm has a shape of a rectangular hyperbola, a nonspecific binding isotherm is linear in the same ligand concentration region. A 1:2 specific binding stoichiometry was revealed with the second binding having a similar affinity compared to the first binding event.},

Surface polishing results in an Al-Cu-Mg particle surface that contains metallic Cu as well as an overlayer of aluminum and magnesium oxide, while larger amounts of aluminum oxide are present on the Al-Cu-Fe-Mn particle and matrix. When dipped in an acidic ZPO coating solution, the oxide covering the Al-Cu-Mg particle is etched most easily, and metallic Cu near the surface makes that region most cathodic, allowing more coating deposition compared with the other regions. The oxides on the Al-Cu-Fe-Mn and matrix regions are similar, thereby confirming that the observed differences in ZPO coating characteristics at these two regions arise from their underlying electrochemical characteristics. Immersion of a coated 2024-Al sample in corrosive NaCl solution for extended periods indicates that the ZPO provides better protection to the second-phase particles than to the matrix.

Precipitation of 3 from the MeOH solution, even under H-2, causes sequestration of the Rh and complete suppression of the catalytic activity. (In a previously studied system with the corresponding, non-hydroxy-substituted ketimine, PhC(Me) = NCH2Ph, the Rh was sequestered as an inactive o-metalated species). The solid state structure of 3 is retained in CH2Cl2 solution, but in MeOH and Me2CO reversible loss of the ketimine generates the cis-[Rh(PPh3)(2)(solvent)(2)]PF6 species. (c) 2006 Elsevier B.V.

Delta E-KS is the difference in the total Kohn-Sham energies of the 2p-ionized cation and the neutral parent molecule calculated by DFT using different exchange-correlation functionals E-xc with triple-zeta polarized basis set, at molecular geometry optimized by HF/6-31G(d), and relativistic effects have been estimated by scalar zeroth-order regular approximation. Among the 26 functionals tested, the form of E-xc giving the best overall performance was found to be the combination of OPTX exchange and LYP correlation functionals. For that functional, the average absolute deviation (AAD) of the 145 calculated CEBEs from experiment is 0.26 cV. There are seven other exchange-correlation functionals that led to AADs of less than 0.30 eV. Some functionals give lower AADs than E-xc=OPTX-LYP for some individual elements. In the case of Si, for example, the combination of either mPW91-PBE or Becke88-Perdew86 led to an AAD of only 0.10 eV for 56 silicon-containing molecules. Another example is the case of the argon atom, for which the choice of E-xc=OPTX-Perdew86 yields a value for CEBE equal to the experimental value. (c) 2005 Elsevier B.V. All rights reserved.},

A procedure for generating diffuse functions to be added to standard Slater-type orbital basis sets for H to Kr is proposed and tested on ten close-shell molecules. The database for comparing the performance of standard and augmented basis sets consists of the 15 lowest transitions to valence and Rydberg-like states for each of the molecules. The results of this computational study are very encouraging. The addition of new augmenting functions improves the performance of standard basis sets significantly. For example, the new augmented TZP basis set, about the same size as the standard TZ2P set (and considerably smaller than the large QZ4P set), led to an average absolute deviation of 150 predicted excitation energies of only 0.12 eV from those obtained with the very large basis set called QZ3P-3DIFFUSE, compared to 0.83, 0.79, and 0.19 eV, for the standard TZP, TZ2P, and QZ4P sets, respectively. Similar augmenting functions for Gaussian-type orbital basis sets for H to Kr are also suggested.},

	abstract = {NMR imaging has been used to study the release behavior of two model drugs, triflupromazine-HCl and 5-fluorouracil, from swelling hydroxypropylmethylcellulose (HPMC) tablets. Preliminary experiments were performed on equilibrium mixtures of drug, polymer and water to determine how properties such as NMR relaxation parameters and self-diffusion were affected by the drug and polymer concentrations. The tablet swelling was restricted to one dimension and distributions of the water and model drugs were obtained by H-1 and F-19 imaging, respectively. The HPMC distribution at each time in the swelling process was determined indirectly from its effect on the relaxation parameters of the water and the drugs. In the one-dimensional swelling tablet, distributions of drug and polymer were compared to determine what factors influenced the release of drug from the swelling tablet. The distributions for triflupromazine-HCl and HPMC paralleled each other and the drug was only released at the eroding edge of the tablet where the HPMC concentration dropped below 10\%. In contrast, 5-fluorouracil was released much more rapidly from the tablet and appeared to escape by diffusion from regions as high as 30\% HPMC. An empirical measure of the rate of tablet edge movement can be obtained from plots of the edge position as a function of the square root of time. For HPMC, the rate of tablet expansion was determined in this way to be (2.4+/-0.8)x10(-6) cm(2) s(-1). The self-diffusion of triflupromazine-HCl in equilibrated mixtures of similar composition to the eroding tablet edge is similar to 3x10(-6) cm(2) s(-1) while the self-diffusion coefficient of 5-fluorouracil remained higher than this value until the HPMC concentration reached about 30\%. This comparison of {\textquoteright}diffusion{\textquoteright} properties may be useful in predicting the mechanism of drug release from other swelling hydrophilic matrix systems.

	abstract = {X-ray photoelectron spectroscopy has been used to characterize thin films of MoO3 formed on planar oxidized supports, namely AlOx (from aluminum strip) and SiO2 (from silicon wafer). Comparisons are made with behaviour for MoO3 on metallic Mo substrate. It is observed that on calcination at 450 degrees C, the Mo 3d spectral features shift to higher binding energy for MoO3/AlOx and to lower binding energy for MoO3/SiO2, On nitridation by heating in NH3, it is found that the samples on the oxide supports show easier O-N replacement compared with the MoO3/Mo system. In general, the nitridation behaviour for MoO3/AlO, is similar to that of MoO3/Mo, but Mo species in MoO3/SiO2 seem to be more easily reduced (Mo(0) is detected for the SiO2 system but not for AlOx). Comparisons of heating rates for the second nitridation step from 350 to 450 degrees C were made for the MoO3/Mo and MoO3/AlOx samples. Differences between the high heating rate (100 K/h) and the low heating rate (40 K/h) are incremental but definite. The lower heating rate is favourable both for the O-N replacement and for the metal reduction. For example, more Mo(+3) is present after the nitridation to 450 degrees C when the low-heating rate regime is used, compared with that formed when the heating is done at the higher rate.

	abstract = {NMR imaging has been used to investigate the in situ swelling behavior of 2-hydroxypropylmethylcellulose (HPMC) tablets in a sample geometry chosen for the simplicity of its diffusion behavior. Preliminary H-1 NMR spectroscopy experiments were performed on equilibrated mixtures of HPMC and water. From these, the dependence of the H-1 T-1 and T-2 relaxation parameters of the water protons with respect to HPMC weight percent were obtained. Further analysis of the T-2 values and H-1 z-spectroscopic data revealed that as the polymer concentration was increased from 10\% to 20\% w/w HPMC, the polymer mobility decreased substantially. One-dimensional NMR imaging of H-1 in the swelling tablet system was used to monitor the movement of water into the polymer and to calculate the T-2 parameters across the system. HPMC weight percents were calculated from these T-2 values using the previously determined calibration. HPMC distributions were determined for two tablet thicknesses. Similar swelling behavior was observed for both thicknesses at early times prior to the thinner tablet becoming completely hydrated.},

	abstract = {A comprehensive theory is proposed to describe the migration behavior of analytes in capillary electrophoresis (CE) when one or more additives are present in the buffer solution. This theory amalgamates and extends the previous work done by others. The capacity factor (k{\textquoteright}) in this theory is defined as the product of the equilibrium constant and the additive concentration, thus, k{\textquoteright} changes linearly with additive concentration, The net electrophoretic mobility of an analyte is a function of k{\textquoteright}, therefore, it can be changed by varying the additive concentration. Three parameters are needed to predict the mobility of an analyte in a one-additive CE system: the mobility of the free analyte, the mobility of the complex, and the equilibrium constant for the analyte-additive interaction (which determines the fraction of the free analyte at different additive concentrations). When additives are used, the change in viscosity obscures this relationship, therefore, a viscosity correction factor is required to convert all mobilities to an ideal state where the viscosity remains constant. The migration behavior of an analyte in a solution with multiple additives can be predicted and controlled, once the equilibrium constants of the interactions between the analyte and each of the additives are obtained separately. beta-Cyclodextrin and hydroxypropyl-beta-cyclodextrin are used as additives and the migration behavior of phenol, p-nitrophenol, and benzoic acid are studied as a model system to verify this theory. When the necessary viscosity correction factor is included, the net electrophoretic mobilities of the analytes obtained from experimental results agree with the values predicted by the theory based on dynamic complexation. Although only experiments with one and two additives were carried out to verify the theory, the equations apply to situations when more than two additives are used. The relationship between the theories of electrophoresis and chromatography is clarified.},

At these surfaces the amphiphiles adsorb similarly, in a non-cooperative manner, achieving a plateau (approximate to 0.1 PEG chains/nm(2)) well below amphiphile critical micelle concentration (CMC). The resultant PEG-enriched layers were 10-15 nm thick, with a polymer concentration (approximate to 0.07 g/cm(3)) greater than the PEG-enriched phase of many dextran, PEG aqueous two-phase systems. PEG-amphiphile adsorption (mg/m(2)) at hydrophobic and phospholipid flat surfaces correlated with changes in the partition (log K) of PC liposomes in such two-phase systems.

	abstract = {The solutes m-dichlorobenzene, o-dichlorobenzene. p-dichlorobenzene, o-dicyanzene, furan, tetrathiofulvalene, and fluorobenzene are studied in the zero electric field gradient mixtures 56.5 wt \% 1132/EBBA and 70 wt \% 5CB/EBBA using proton NMR. The two second-rank-order parameters obtained for each solute from analysis of the NMR spectra indicate that the solutes experience a similar anisotropic potential in both mixtures. The results are interpreted in terms of two models for the short-range anisotropic potential experienced by the solutes.},

	abstract = {{Treatment of Cp*M(NO)Cl2 (Cp* = eta5-C5Me5; M = Mo, W) with arylamines, ArNH2 (Ar = phenyl, o-tolyl, or p-tolyl) affords 18-valence-electron adducts of the type Cp*M(NO)Cl2.NH2-Ar. These adducts can be dehydrohalogenated with a strong base to produce the amido chloro complexes Cp*M(NO)(NHAr)Cl in good yields. These latter complexes can also be prepared by treatment of Cp*M(NO)Cl2 with 1 equiv of a lithium amide. Interestingly, treatment of Cp*M(NO)Cl2 with excess primary alkylamines produces directly the amido chloro complexes, Cp*M(NO)(NHR)CI(R=alkyl). Mixed alkyl amido and alkoxo amido complexes are preparable by sequential treatment of Cp*M(NO)Cl2 with 1 equiv of an alkylating reagent or lithium alkoxide followed by treatment with excess alkylamine. The solid-state molecular structures of the two representative complexes, Cp*Mo(NO)Cl2.PhNH2 (1) and Cp*W(NO)(OCMe3)-(NHCMe3) (18) have been established by single-crystal X-ray diffraction analyses. Crystals of 1 are monoclinic, space group P2(1)/c, with a = 8.590(1) angstrom},
