Geological Journal, EarlyView.This study reports the exceptional preservation of the Eocene freshwater bivalve Batissa sitakaraensis from Hokkaido, Japan. Multimodal analyses reveal that both the aragonitic shell mineralogy and the delicate organic periostracum retain their original structural and chemical characteristics after millions of years.

Bio-catalyzed Aerobic Oxidation Reactions
, 2020 Oxidoreductase enzymes enable a large variety of oxidation and oxyfunctionalization reactions at the expense of molecular oxygen, which is most commonly used in the form of air and at atmospheric pressure. Over the past decade, the number of available enzymes and methodologies enabling the performance of these types of reactions has increased ...

Aerobic oxidations catalyzed by catechol
Biochimica et Biophysica Acta (BBA) - Biophysics including Photosynthesis, 1966Abstract 1. 1. Catechol catalyzes the aerobic oxidation of p -hydroquinones, p -semiquinones and very probably also of o -semiquinones. 2. 2. It appears that catechol activates the oxygen molecule through a charge-transfer complex. 3. 3.

Organocatalyzed Aerobic Oxidation of Aldehydes to Acids
Organic Letters, 2019The first example organocatalyzed aerobic oxidation of aldehydes to carboxylic acids in both organic solvent and water under mild conditions is developed. As low as 5 mol % N-hydroxyphthalimide was used as the organocatalyst, and molecular O2 was used as the sole oxidant. No transition metals or hazardous oxidants or cocatalysts were involved.

Aerobic Oxidations Catalyzed by Colloidal Nanogold
Chemistry – An Asian Journal, 2011AbstractRecently, dispersions of gold nanoclusters in liquid media (colloidal nanogold) have been extensively used as quasi‐homogeneous catalysts for various aerobic oxidation reactions. This review describes recent progress in such reactions, with a focus on our comprehensive studies on gold clusters (<2 nm) stabilized by poly(N‐vinyl‐2‐pyrrolidone)

Ruthenium‐Catalyzed Aerobic Oxidation of Amines
Chemistry – An Asian Journal, 2018AbstractAmine oxidation is one of the fundamental reactions in organic synthesis as it leads to a variety of value‐added products such as oximes, nitriles, imines, and amides among many others. These products comprise the key N‐containing building blocks in the modern chemical industry, and such transformations, when achieved in the presence of ...
