Influence of diluent alkyl substitution on the extraction of Am(III) and Eu(III) by a 6,6’-bis(1,2,4-triazin-3-yl)-2,2’-bipyridine ligand dissolved in alkylated cyclohexanone Diluents
No full textSeveral alkylated cyclohexanones were investigated as potential diluents for the selective extraction of Am(III) from Eu(III) from nitric acid solutions by the CyMe4-BTBP ligand. No significant extraction of either of the metal ions was observed for these diluents themselves. In the extractions from 1 M HNO3, 3-methylcyclohexanone and 4-methylcyclohexanone gave comparable results to cyclohexanone whereas in the extractions from 4 M HNO3, 2-methylcyclohexanone, 3-methylcyclohexanone and 4-methylcyclohexanone all gave superior results. For the monomethylated diluents, DAm and SFAm/Eu decreased in the order of alkyl substitution 2 > 4 ~ 3. However, alkyl substitution of cyclohexanone significantly slows down the extraction kinetics compared to cyclohexanone, and the position of alkyl substitution was found to play an important role in the solvents properties. 3-Methylcyclohexanone was identified as the most promising of the diluent
Doctor-family-patient relationship: The Chinese paradigm of informed consent
No full textBioethics is a subject far removed from the Chinese, even from many Chinese medical students and medical professionals. In-depth interviews with eighteen physicians, patients, and family members provided a deeper understanding of bioethical practices in contemporary China, especially with regard to the doctor-patient relationship (DPR) and informed consent. The Chinese model of doctor-family-patient relationship (DFPR), instead of DPR, is taken to reflect Chinese Confucian cultural commitments. An examination of the history of Chinese culture and the profession of medicine in China is used to disclose the deep roots of these commitments. The author predicts that the DFPR model will further develop in China but that it will maintain its Chinese character.EthicsSocial Sciences, BiomedicalPubMedCPCI-SSH(ISSHP)SSCI4

No full textSpin-Crossover in Supramolecular Iron(II)-2,6-bis(1 H-Pyrazol-1-yl)pyridine Complexes: Toward Spin-State Switchable Single-Molecule Junctions
No full textSpin-crossover (SCO) active iron(II) complexes are an integral class of switchable and bistable molecular materials. Spin-state switching properties of the SCO complexes have been studied in the bulk and single-molecule levels to progress toward fabricating molecule-based switching and memory elements. Supramolecular SCO complexes featuring anchoring groups for metallic electrodes, for example, gold (Au), are ideal candidates to study spin-state switching at the single-molecule level. In this study, we report on the spin-state switching characteristics of supramolecular iron(II) complexes 1 and 2 composed of functional 4-([2,2′-bithiophen]-5-ylethynyl)-2,6-di(1H-pyrazol-1-yl)pyridine (L1) and 4-(2-(5-(5-hexylthiophen-2-yl)thiophen-2-yl)ethynyl)-2,6-di(1H-pyrazol-1-yl)pyridine (L2) ligands, respectively. Density functional theory (DFT) studies revealed stretching-induced spin-state switching in a molecular junction composed of complex 1, taken as a representative example, and gold electrodes. Single-molecule conductance traces revealed the unfavorable orientation of the complexes in the junctions to demonstrate the spin-state dependence of the conductance.QN/van der Zant La
LOWER RANGE OF STRINGOCEPHALUS
No full textThe lower range of Stringocephalus around the world is considered within the Givetian under the SDS (Subcommission on Devonian Stratigraphy) newly proposed definition of the Eifelian/Givetian boundary. However, in a measured section at Liujing (Guangxi, China), in which conodonts and silicified brachiopods occur in the same samples, Stringocephalus occurs in a shelf-edge fauna in beds that yield conodonts diagnostic of the lower part of the ensensis Zone of the uppermost Eifelian.GeologySCI(E)0ARTICLE273-773
(2E)-1-(2,4-Dimethylquinolin-3-yl)-3-(thiophen-2-yl)prop-2-en-1-oneAdditional correspondence author, e-mail: [email protected].
No full textTwo independent but virtually identical molecules comprise the asymmetric unit in the title compound, C18H15NOS. With reference to the quinolin-3-yl group, the 3-(thiophen-2-yl)prop-2-en-1-one residue is almost perpendicular, with all but the carbonyl O atom lying to one side of the plane. This conformation is reflected by the C—C—C—C torsion angles of −102.2 (3) and 81.1 (3)° in the two independent molecules. The dihedral angle formed between the 13 non-H atoms directly associated with the quinolin-3-yl group and the thiophen-2-yl ring is 87.70 (11)° [83.85 (10)° for the second independent molecule]. The presence of C—H...O, C—H...N and π–π interactions [centroid–centroid distance = 3.5590 (12) Å] lead to supramolecular chains along the c-axis direction. These are connected along the a-axis direction by C—H...π interactions. The resultant supramolecular layers stack along the b axis
Density functional theory calculations on (2e)-3-(3-Bromo-4-methoxyphenyl)-1-(pyridin-2-yl) prop-2-en-1-one
No full text32nd International Physics Congress of Turkish-Physical-Society (TPS) -- SEP 06-09, 2016 -- Bodrum, TURKEYIn this paper, quantum chemical calculations of (2e)-3-(3-Bromo-4-methoxyphenyl)-1-(pyridin-2-yl)-prop-2-en1-one were performed by using B3LYP and CAMB3LYP levels of density functional theory (DFT) with 6-31 1++G(d, p) basis set. Geometric parameters of the title molecule in the ground state were found to be in good agreement with experimental data. C-13 and H-1 NMR chemical shifts were calculated within GIAO approach which is one of the most common approaches. The frontier molecular orbitals (HOMO and LUMO) were simulated by the same levels. Nonlinear optical parameters (NLO) were also evaluated by determining of dipole moment, polarizability and first hyperpolarizability. All of calculations were carried out Gaussian 09 package program
