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
Get PDFSeveral 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

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

Get PDFSpin-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
Highly fluorescent supramolecular gels with chirality transcription through hydrogen bonding
No full textA highly fluorescent organogel with transparency was formed through a hydrogen (H)-bonding interaction between a non. fluorescent and achiral 2-(3',5'-bis-trifluoromethyl-biphenyl-4-yl)-3-(4-pyridin-4-yl-phenyl)-acrylonitrile (CN-TFMBPPE) monomer and chiral sergeant L-tartaric acid (TA) (or D-TA), with gel formation being accompanied by a drastic fluorescence enhancement as well as chirality induction.
