Separation of Branched Poly(bisphenol A carbonate) Structures by Solvent Gradient at Near-Critical Conditions and Two-Dimensional Liquid Chromatography.

Analytical chemistry

Apel N, Uliyanchenko E, Moyses S, Rommens S, Wold C, Macko T, Brüll R.
PMID: 29600700
Anal Chem. 2018 Apr 17;90(8):5422-5429. doi: 10.1021/acs.analchem.8b00618. Epub 2018 Apr 04.

Branching is a molecular metric that strongly influences the application properties of polymers. Consequently, detailed information on the microstructure is required to gain a deeper understanding of structure-property relationships. In the present case, we employ high-performance liquid chromatography to...

Apfel J, Reischmann P, Müller O.
PMID: 24066239
ISRN Oncol. 2013 Aug 28;2013:603129. doi: 10.1155/2013/603129. eCollection 2013.

The dysregulated Wnt pathway is a major cause for the activation of cell proliferation and reduced differentiation in tumor cells. Therefore the Wnt signaling pathway is the on-top target in searching for new anticancer drugs or therapeutic strategies. Although...

We report an unprecedented dinuclear catalyst for the electrochemical hydrogen evolution reaction (HER). A macrocyclic porphyrin complex comprising two nickel centres connected via redox mediating linker molecules gives rise to efficient catalysis, significantly outperforming a mononuclear reference catalyst.
