Abstract

Radiation and hydrolytic resistance of Eu0.054Gd0.014Y0.05La0.111Ce0.2515Pr0.094Nd0.3665Sm0.059PO4 with monazite structure has been studied. The powders were obtained by deposition from solutions. Ceramic specimens with relative density ~97% were obtained by Spark Plasma Sintering (heating rate Vh = 50 {\deg}C/min, sintering temperature Ts = 1070 {\deg}C, sintering time ts = 18 min). Irradiation by accelerated electrons up to dose of 10^9 Ge was found not to result in a destruction of the target phase. After the irradiation, an increasing of the leaching rate by an order of magnitude (up to ~10^{-8} g/(cm2*day)) and a reduction of the mechanical properties by 32% as compared to the non-irradiated ceramic specimen were observed., Comment: 11 pages, 6 figures, one table

Abstract

Psoriasis is an inflammatory skin disease that is associated with many comorbidities. Several psoriasis treatments approved by the United States Food and Drug Administration have been shown to have beneficial effects on these comorbidities, while others might lead to an exacerbation of these conditions. In this article, we review studies of psoriasis treatments and their level of evidence for use in co-occurring diseases. An awareness of the multifaceted effects of certain psoriasis medications can enable physicians to provide more personalized treatment to their most complicated patients.

Abstract

Nuclear spin polarization can be significantly increased through the process of hyperpolarization, leading to an increase in the sensitivity of nuclear magnetic resonance (NMR) experiments by 4–8 orders of magnitude. Hyperpolarized gases, unlike liquids and solids, can often be readily separated and purified from the compounds used to mediate the hyperpolarization processes. These pure hyperpolarized gases enabled many novel MRI applications including the visualization of void spaces, imaging of lung function, and remote detection. Additionally, hyperpolarized gases can be dissolved in liquids and can be used as sensitive molecular probes and reporters. This Minireview covers the fundamentals of the preparation of hyperpolarized gases and focuses on selected applications of interest to biomedicine and materials science.

43. Electrochemical ortho functionalization of 2-phenylpyridine with perfluorocarboxylic acids catalyzed by palladium in higher oxidation states

Abstract

The electochemical oxidation of palladium acetate or palladium perfluoroacetate in the presence of 2-phenylpyridine promotes catalytic ortho C-H substitution reactions. As possible intermediates, Pd(II) metallacycles with Pd-bound acetate, perfluoroacetate, and perfluoroheptanoate substituents have been isolated and characterized: binuclear [(PhPy)Pd(μ-OAc)]2 and [(PhPy)Pd(μ-TFA)]2 and mononuclear [(PhPy)Pd(TFA)](CH 3CN), [(PhPy)Pd(TFA)](PhPy), and [(PhPy)Pd(PFH)](PhPy). The fluorinated derivatives were found to exist in solvent-dependent equilibria between mononuclear and binuclear forms. Cyclic voltammetry was used to elucidate redox properties of the palladacycles and the oxidation route to the final products. © 2013 American Chemical Society.
