The stability and reactivity of the hematite, Fe2O3(0001) surface are studied by density functional theory including an on-site Coulomb term (DFT+U). Even under oxygen rich conditions, the metal-terminated surface is shown ...

Fluorescence microscopy imaging enables receptor proteins to be investigated within their biological context. A key challenge is to site-specifically incorporate reporter moieties into proteins without interfering with ...

Mononuclear Cr(III)-silica models have been studied by quantum chemical methods with respect to catalytic activity toward dehydrogenation of ethane. Both cluster and slab models have been developed and used to explore the ...

Selenium deficiency constitutes a risk factor for the incidence and negative course of severe diseases including sepsis, stroke, autoimmune diseases or cancer. In this study, hypoxia is identified as a powerful stimulus ...

Es wird eine neue Hämolysierlösung für die Glucosebestimmung mit der Glucosedehydrogenase-Methode am AutoAnalyzer H beschrieben. Außerdem wurde ein Vergleich mit einer anderen Hämolysierlösung (Boehringer) durchgeführt. ...

The spectrophotometric method for the determination of angiotensin-converting enzyme in serum usin p-hydroxyhippuryl-L-histidyl-L-leucine as substrate is commercially available as a test kit. It shows excellent linearity ...
