Gas-liquid mass transfer with parallel reversible reactions—II. Absorption of CO2 into amine-promoted carbonate solutions [PDF]
, 1989 A numerical method developed by Verteeg (1989, Chem. Engng Sci.44, 2295–2310; 1990, Chem. Engng Sci.45, in press) is applied to the absorption of CO2 into amine-promoted carbonate solutions. The experimental results of Savage (1984, Faraday Discuss. Chem.

Update: Enzymatische Synthese für industrielle Anwendungen
Angewandte Chemie, EarlyView.Die Biokatalyse hat sich zu einer nachhaltigen und wettbewerbsfähigen Alternative zur herkömmlichen chemischen Synthese entwickelt und ermöglicht die enzymbasierte Herstellung nicht nur von chemischen Grundstoffen, sondern auch von (nicht natürlichen) Aminosäuren, (seltenen) Zuckern und synthetischen Nukleotiden.

CO_2-inhibition of the amplitude of bending of triton-demembranated sea urchin sperm flagella [PDF]
, 1977 Demembranated sea urchin spermatozoa were reactivated in solutions containing KHCO_3 and observed in a covered well slide. Although KHCO_3 itself causes a small inhibition of flagellar beat frequency, the results confirm previous observations of a direct

Angewandte Chemie International Edition, EarlyView.We present a metal‐free method for aromatic deuterium labeling via photoexcitation in deuterated HFIP. This approach leverages the enhanced basicity of excited‐state aromatics to achieve selective hydrogen isotope exchange at challenging positions. Demonstrated on complex drug molecules, this efficient strategy provides a valuable tool for isotope ...
