A parallel-plate flow chamber to study initial cell adhesion on a nanofeatured surface [PDF]
, 2004 Cells in the human body come across many types of information, which they respond to. Both material chemistry and topography of the surface where they adhere have an effect on cell shape, proliferation, migration, and gene expression.

Modeling the Enceladus plume--plasma interaction
, 2010 We investigate the chemical interaction between Saturn's corotating plasma and Enceladus' volcanic plumes. We evolve plasma as it passes through a prescribed H2O plume using a physical chemistry model adapted for water-group reactions.

Chiral separation in microflows [PDF]
, 2005 Molecules that only differ by their chirality, so called enantiomers, often possess different properties with respect to their biological function. Therefore, the separation of enantiomers presents a prominent challenge in molecular biology and belongs ...

FEBS Letters, EarlyView.Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Photocatalytic trifluoromethoxylation of arenes and heteroarenes in continuous-flow
Beilstein Journal of Organic Chemistry, 2020 The first example of photocatalytic trifluoromethoxylation of arenes and heteroarenes under continuous-flow conditions is described. Application of continuous-flow microreactor technology allowed to reduce the residence time up to 16 times in comparison ...

Special issue in flow chemistry [PDF]
Molecular Diversity, 2011 In the last decade, we havewitnessed a steady transformation of organic chemistry. The number of launched new chemical entities decreased in spite of the number of synthetically accessible small molecules that exponentially increased. On the other hand, the drug like chemical space was only poorly sampled and the huge compound decks at Big Pharma ...
