Carbon Dioxide Migration Pathways in Proteins

Carbon dioxide concentration dictates alternative methanogenic pathways in oil reservoirs

Deep subsurface formations (for example, high-temperature oil reservoirs) are candidate sites for carbon capture and storage technology. However, very little is known about how the subsurface microbial community would respond to an increase in CO2 pressure resulting from carbon capture and storage. Here we construct microcosms mimicking reservoir conditions (55 °C, 5 MPa) using high-temperature...

Ligand migration and escape pathways in haem proteins.

Biophysical techniques developed during the last three decades have provided an increasingly detailed description of the internal processes associated with ligand capture and release by haem proteins. Myoglobin has long been the paradigm for these studies. More recently, cytochrome P450cam (the camphor-metabolizing cytochrome P450 from Pseudomonas putida) has also received considerable interest...

Catalytic Cyclocarbonylation in Compressed Carbon Dioxide: Pressure Influence of Carbon Monoxide and Carbon Dioxide

Among the current interests in organic synthesis are those reactions performing multiple C-C bond formation, in special when they undergo under catalytic conditions. Due to its properties, there is a growing interest on the use of compressed fluids (CF) as solvent media in catalytic processes. In this context, we present herein studies that aim to the development of a cleaner technology for the...

Keeping carbon dioxide in check

The response of the brainstem to increased levels of carbon dioxide in the blood is coordinated with the response of the cardiovascular system.
