Competition between stacking and hydrogen bonding: theoretical study of the phenol...Ar cation and neutral complex and comparison to experiment.

Physical chemistry chemical physics : PCCP

Cerný J, Tong X, Hobza P, Müller-Dethlefs K.

Phys Chem Chem Phys. 2008 May 21;10(19):2780-4. doi: 10.1039/b801460b. Epub 2008 Apr 11.

Experimental results obtained previously for vdW-bonded and H-bonded phenol...argon (PhOH...Ar) complexes in their S(0) and D(0) states are combined with ab initio quantum-chemical theoretical results. Such a combination allows us to present a "complete" description of the geometry, relative...

Role of Aquaporins during Teleost Gametogenesis and Early Embryogenesis.

Frontiers in physiology

Chauvigné F, Zapater C, Cerdà J.
PMID: 21994496
Front Physiol. 2011 Sep 30;2:66. doi: 10.3389/fphys.2011.00066. eCollection 2011.

Aquaporins are believed to be involved in homeosmotic mechanisms of marine teleosts. Increasing data suggest that these molecular water channels play critical roles associated with the adaptation of gametes and early embryos to the external spawning environment. In this...

The structural state of lead-based relaxor ferroelectrics under pressure.

IEEE transactions on ultrasonics, ferroelectrics, and frequency control

Mihailova B, Angel RJ, Maier BJ, Welsch AM, Zhao J, Gospodinov M, Bismayer U.
PMID: 21937324
IEEE Trans Ultrason Ferroelectr Freq Control. 2011 Sep;58(9):1905-13. doi: 10.1109/TUFFC.2011.2030.

The exceptional properties of lead-based perovskite-type (ABO(3)) relaxor ferroelectrics are due to their structural inhomogeneities. At ambient conditions, the average structure is pseudocubic but rich in ferroic nanoregions too small to be directly studied by conventional diffraction analysis. However,...

Synthesis and molecular structure of beta-phosphinoyl carboxamides: an unexpected case of chiral discrimination of hydrogen-bonded dimers in the solid state.

Chemistry (Weinheim an der Bergstrasse, Germany)

Alajarín M, López-Leonardo C, Alvarez-García A, Llamas-Lorente P, Sánchez-Andrada P, Berná J, Pastor A, Bautista D, Jones PG.

Chemistry. 2010 Mar 22;16(12):3728-35. doi: 10.1002/chem.200901845.

A series of N,P,P-trisubstituted aminophosphanes react with diphenylcyclopropenone to afford an easily separable mixture of two diastereomeric alpha,beta-diphenyl-beta-phosphinoyl carboxamides in good yields. X-ray crystal structures reveal that these compounds associate into dimers, formed from two enantiomeric units linked by...

Exposure of breast-fed children in the Czech Republic to PCDDs, PCDFs, and dioxin-like PCBs.

Environmental toxicology and pharmacology

Human milk samples from 81 mothers living in seven selected localities of the Czech Republic collected in 1999-2000 were analyzed for PCDDs, PCDFs, and dioxin-like PCBs. Significant local differences in total WHO-TEQ values were observed (median ranges: 27.8-64.6pg/g fat)...

The remarkable electronic properties of graphene strongly depend on the thickness and geometry of graphene stacks. This wide range of electronic tunability is of fundamental interest and has many applications in newly proposed devices. Using the mid-infrared, magneto-optical Kerr...

The title compound, [Cu(2)(OH)(2)(C(6)H(16)N(2))(2)(H(2)O)](BF(4))(2), consists of dinuclear centrosymmetric [Cu(2)(OH)(2)(tmen)(2)(H(2)O)](2+) complex cations (tmen = N,N,N',N'-tetra-methyl-ethane-1,2-diamine) and tetra-fluoridoborate anions. In the cation, the Cu(II) atom shows a slightly distorted square-pyramidal coordination geometry provided by a pair of μ-OH(-) anions and by...
