The electronic and steric properties of tailored cyclopentadienyl (Cp) ligands are powerful handles to modulate the catalytic properties of their metal complexes. This requires the individual preparation, purification and storage of each ligand/metal combination. Alternative, ideally

Microarray analysis of nitric oxide responsive transcripts in Arabidopsis.

Plant biotechnology journal

Parani M, Rudrabhatla S, Myers R, Weirich H, Smith B, Leaman DW, Goldman SL.
PMID: 17134397
Plant Biotechnol J. 2004 Jul;2(4):359-66. doi: 10.1111/j.1467-7652.2004.00085.x.

Nitric oxide (NO) is emerging as an important signalling molecule with diverse physiological functions in plants. In the current study, changes in gene expression in response to 0.1 mm and 1.0 mm sodium nitroprusside (SNP), a donor of NO,...

Electrochemical behavior of titanium-based materials - are there relations to biocompatibility?.

Journal of materials science. Materials in medicine

Scharnweber D, Beutner R, Rössler S, Worch H.
PMID: 15348668
J Mater Sci Mater Med. 2002 Dec;13(12):1215-20. doi: 10.1023/a:1021118811893.

For biomedical applications the physico-chemical properties of oxide layers, always present in titanium-based materials, are of special interest because the biological system is in direct contact only with these oxides. Using electrochemical impedance spectroscopy and galvanostatic polarization it is...

How accurate are DFT treatments of organic energies?.

Organic letters

Wodrich MD, Corminboeuf C, Schreiner PR, Fokin AA, von Ragué Schleyer P.

Org Lett. 2007 May 10;9(10):1851-4. doi: 10.1021/ol070354w. Epub 2007 Apr 07.

Increasing awareness that popular functionals fail to describe many energies accurately has ended expectations of black-box DFT usage. The performance of nine density functionals, compared by computing the bond separation energies of 72 illustrative hydrocarbons with available experimental data,...

Effects of halogen substitution on the properties of eight- and nine-vertex closo-boranes.

Dalton transactions (Cambridge, England : 2003)

Corminboeuf C, Wodrich MD, King RB, von Ragué Schleyer P.
PMID: 18354772
Dalton Trans. 2008 Apr 07;(13):1745-51. doi: 10.1039/b716323a. Epub 2008 Feb 29.

The symmetry constrained geometries of the eight- and nine-vertex polyhedral boranes and haloboranes BnXnz (n = 8 and 9; X = H, F and Cl; z = -2, -1 and 0) were optimized at the B3LYP/6-311+G(d) level and their...

Empirical corrections to density functional theory highlight the importance of nonbonded intramolecular interactions in alkanes.

The journal of physical chemistry. A

Wodrich MD, Jana DF, Schleyer Pv, Corminboeuf C.
PMID: 18925729
J Phys Chem A. 2008 Nov 13;112(45):11495-500. doi: 10.1021/jp806619z. Epub 2008 Oct 17.

Energies of alkanes computed with many popular and even newer density functionals are flawed by systematic errors, which become considerable with larger molecules. The same energies, however, are well described by post-Hartree-Fock methods. Similar DFT shortcomings are well documented...

Double aromaticity in monocyclic carbon, boron, and borocarbon rings based on magnetic criteria.

Chemistry (Weinheim an der Bergstrasse, Germany)

Wodrich MD, Corminboeuf C, Park SS, Schleyer Pv.
PMID: 17431868
Chemistry. 2007;13(16):4582-93. doi: 10.1002/chem.200700154.

The double-aromatic character of selected monocyclic carbon, boron, and borocarbon rings is demonstrated by refined nucleus-independent chemical shift (NICS) analyses involving the contributions of individual canonical MOs and their out-of-plane NICS tensor component (CMO-NICS(zz)). The double aromaticity considered results...

Bimetallic oxidative addition involving radical intermediates in nickel-catalyzed alkyl-alkyl Kumada coupling reactions.

Journal of the American Chemical Society

Breitenfeld J, Ruiz J, Wodrich MD, Hu X.
PMID: 23865460
J Am Chem Soc. 2013 Aug 14;135(32):12004-12. doi: 10.1021/ja4051923. Epub 2013 Aug 01.

Many nickel-based catalysts have been reported for cross-coupling reactions of nonactivated alkyl halides. The mechanistic understanding of these reactions is still primitive. Here we report a mechanistic study of alkyl-alkyl Kumada coupling catalyzed by a preformed nickel(II) pincer complex...

Functional Resistance to Recurrent Spatially Heterogeneous Disturbances Is Facilitated by Increased Activity of Surviving Bacteria in a Virtual Ecosystem.

Bacterial degradation of organic compounds is an important ecosystem function with relevance to, e.g., the cycling of elements or the degradation of organic contaminants. It remains an open question, however, to which extent ecosystems are able to maintain such...

Endothelin-1 as a Risk Factor in Retinal Vein Occlusion.

Retina (Philadelphia, Pa.)

PURPOSE: Retinal vein occlusion (RVO) risk factors largely coincide with cardiovascular risk factors. Endothelin-1 (ET-1), the most potent vasoconstrictor with pro-inflammatory properties, is a known cardiovascular risk factor. In this study, we explore the role of serum ET-1 as...

Medium-term outcome after stented and un-stented distal urethroplasty: A retrospective analysis on redo-urethroplasty need and cosmetic results.
