Chemistry. 2015 Mar 16;21(12):4628-38. doi: 10.1002/chem.201406486. Epub 2015 Feb 11.

The coordination chemistry of cyclic stannylene-based intramolecular Lewis pairs is presented. The P→Sn adducts were treated with [Ni(COD)2] and [Pd(PCy3)2] (COD = 1,5-cyclooctadiene, PCy3 = tricyclohexylphosphine). In the isolated coordination compounds the stannylene moiety acts either as an acceptor...

Promoter, transgene, and cell line effects in the transfection of mammalian cells using PDMAEMA-based nano-stars.

Biotechnology reports (Amsterdam, Netherlands)

Biotechnol Rep (Amst). 2016 Jun 16;11:53-61. doi: 10.1016/j.btre.2016.05.003. eCollection 2016 Sep.

Non-viral transfection protocols are typically optimized using standard cells and reporter proteins, potentially underestimating cellular or transgene effects. Here such effects were studied for two human (Jurkat, HEK-293) and two rodent (CHO-K1, L929) cell lines and three fluorescent reporter...

Recognizing individual faces is an important human ability that highly depends on experience. This is reflected in the so called other-race effect; adults are better at recognizing faces from their own ethnic group, while very young infants do not...

Intramolecular Tetrylene Lewis Adducts: Synthesis and Reactivity.

Chemistry (Weinheim an der Bergstrasse, Germany)

Schneider J, Krebs KM, Freitag S, Eichele K, Schubert H, Wesemann L.
PMID: 27273819
Chemistry. 2016 Jul 04;22(28):9812-26. doi: 10.1002/chem.201601224. Epub 2016 Jun 07.

A series of benzyl(diphenylphosphino) and o-phenyl(diphenlyphosphino) substituted germylenes and plumbylenes were synthesized by nucleophilic substitution between the respective lithium reagent and tetrylene halide. The Lewis pairs were characterized by X-ray crystallography and NMR spectroscopy. The reactivity of the tetrylenes...

Peripheral ligands as electron storage reservoirs and their role in enhancement of photocatalytic hydrogen generation.

Chemical communications (Cambridge, England)

The contrasting early-time photodynamics of two related Ru/Pt photocatalysts with very different photocatalytic H2 generation capabilities are reported. Ultrafast equilibration (535 ± 17 fs) creates an electron reservoir on the peripheral ligands of the ester substituted complex, allowing a...

Common and rare variants of microRNA genes in autism spectrum disorders.
