Structure and magnetic field-induced transition in a one-dimensional hybrid inorganic-organic chain system, Co2(4,4'-bpy)(tfhba)2.4,4'-bpy (4,4'-bpy = 4,4'-bipyridine; tfhba = 2,3,5,6-tetrafluoro-4-hydroxybenzoate).

Two isostructural hybrid inorganic-organic frameworks, M(2)(4,4'-bpy)(tfhba)(2).4,4'-bpy, (M = Co (1), Zn (2); 4,4'-bpy = 4,4'-bipyridine; tfhba = 2,3,5,6-tetrafluoro-4-hydroxybenzoate) have been synthesized and their structures elucidated using single crystal X-ray diffraction. These materials are the first hybrid structures synthesized using...

High temperature magnetic ordering in the 4d perovskite SrTcO3.

Physical review letters

Rodriguez EE, Poineau F, Llobet A, Kennedy BJ, Avdeev M, Thorogood GJ, Carter ML, Seshadri R, Singh DJ, Cheetham AK.
PMID: 21405490
Phys Rev Lett. 2011 Feb 11;106(6):067201. doi: 10.1103/PhysRevLett.106.067201. Epub 2011 Feb 07.

We present evidence for possibly the highest magnetic ordering temperature in any compound without 3d transition elements. Neutron powder diffraction measurements, at both time-of-flight and constant wavelength sources, were performed on two independently prepared SrTcO3 powders. SrTcO3 adopts a...

Biocatalytic synthesis of disaccharide high-intensity sweeterner sucralose via a tetrachlororaffinose intermediate.

Biotechnology and bioengineering

Bennett C, Dordick JS, Hacking AJ, Cheetham PS.

Biotechnol Bioeng. 1992 Jan 20;39(2):211-7. doi: 10.1002/bit.260390213.

A second high-yielding bioorganic synthesis of the highintensity sweetener sucralose (4,1',6'-trichloro-4,1',6'-trideoxygalactosucrose) is described. This procedure involves the chemical chlorination of raffinose to form a novel tetrachloroaffinose intermediate (6,4',1'',6''-tetrachloro-6,4',1'',6''-tetradeoxygalactoraffinose; TCR) followed by the enzymic hydrolysis of the alpha-1-6 glycosidic bond...

Order-disorder antiferroelectric phase transition in a hybrid inorganic-organic framework with the perovskite architecture.

[(CH3)2NH2]Zn(HCOO)3, 1, adopts a structure that is analogous to that of a traditional perovskite, ABX3, with A = [(CH3)2NH2], B = Zn, and X = HCOO. The hydrogen atoms of the dimethyl ammonium cation, which hydrogen bond to oxygen...

The human likeness dimension of the "uncanny valley hypothesis": behavioral and functional MRI findings.

Frontiers in human neuroscience

Cheetham M, Suter P, Jäncke L.
PMID: 22131970
Front Hum Neurosci. 2011 Nov 24;5:126. doi: 10.3389/fnhum.2011.00126. eCollection 2011.

The uncanny valley hypothesis (Mori, 1970) predicts differential experience of negative and positive affect as a function of human likeness. Affective experience of humanlike robots and computer-generated characters (avatars) dominates "uncanny" research, but findings are inconsistent. Importantly, it is...

Van der Waals forces in the perfluorinated metal-organic framework zinc 1,2-bis(4-pyridyl)ethane tetrafluoroterephthalate.

Traditional density functional theory (DFT) and dispersion-corrected DFT calculations are performed to investigate the metal-organic framework zinc 1,2-bis(4-pyridyl)ethane tetrafluoroterephthalate (Znbpetpa). Without dispersion correction, straightening of the zigzag C-O-Zn chain connecting the secondary building units across the diagonal of the...

Refinement of the Cornell et al. Nucleic Acids Force Field Based on Reference Quantum Chemical Calculations of Glycosidic Torsion Profiles.

J Chem Theory Comput. 2011 Sep 13;7(9):2886-2902. doi: 10.1021/ct200162x. Epub 2011 Aug 02.

We report a reparameterization of the glycosidic torsion χ of the Cornell et al. AMBER force field for RNA, χ(OL). The parameters remove destabilization of the anti region found in the ff99 force field and thus prevent formation of...

We report the synthesis, crystal structure and exfoliation of a new member of an important family of layered compounds: lamellar pyrimidinethiolate coordination polymers. Conductivity measurements and DFT calculations of iron(II) pyrimidine-2-thiolate show that this material and a related compound...

A 3D hybrid zinc formate framework, [NH(4)][Zn(HCOO)(3)], possessing an acs topology, shows a high degree of mechanical anisotropy and negative linear compressibility (NLC) along its c axis. High-pressure single-crystal X-ray diffraction studies and density functional theory calculations indicate that...
