Specific Step

I look forward to New Year's resolutions. They challenge me to shape the year ahead, hopefully as a better one than the last. For 2020, I included in my list specific step changes to reduce my own carbon footprint, and there is no better opportunity to discuss this than in the current issue of The Leading Edge, with its special section dedicated to carbon dioxide (CO2).

The topic of carbon dioxide (CO2) in the subsurface relates to enhanced recovery efforts and the fate of CO2 in injection and sequestration scenarios. The papers in this special section address those situations from the perspectives of formation evaluation, injection practices, and time-lapse monitoring. The fields under study in these papers all drastically differ from one another in geologic complexity, so no standard workflow suffices to characterize all of them. These papers paint a good picture of the range of issues associated with the understanding of CO2 in the subsurface.

The Past

In the past decade, the capture of anthropic carbonic dioxide and its storage or transformation have emerged as major tasks to achieve, in order to control the increasing atmospheric temperature of our planet. One possibility rests on the use of carbonic anhydrase enzymes, which have been long known to accelerate the hydration of neutral aqueous CO2 molecules to ionic bicarbonate species. In this paper, the principle underlying the use of these enzymes is summarized. Their main characteristics, including their structure and catalysis kinetics, are presented. A special section is next devoted to the main types of CO2 capture reactors under development, to possibly use these enzymes industrially. Finally, the possible application of carbonic anhydrases to directly store the captured CO2 as inert solid carbonates deserves a review presented in a final section.

Laser Effect

While much is known regarding the effect of lasers on the retina, little study has been done on the effect of lasers on cornea, because of the limitation of the size of the material. Using a combination of electron microscope and several newly developed cytochemical methods, the effect of laser can now be studied on eye for the purpose of correlating functional and morphological damage. The present paper illustrates such study with CO2 laser on Rhesus monkey.

The advent of the scanning electron microscope (SCEM) has renewed interest in preparing specimens by avoiding the forces of surface tension. The present method of freeze drying by Boyde and Barger (1969) and Small and Marszalek (1969) does prevent surface tension but ice crystal formation and time required for pumping out the specimen to dryness has discouraged us. We believe an attractive alternative to freeze drying is the critical point method originated by Anderson (1951; for electron microscopy. He avoided surface tension effects during drying by first exchanging the specimen water with alcohol, amy L acetate and then with carbon dioxide. He then selected a specific temperature (36.5°C) and pressure (72 Atm.) at which carbon dioxide would pass from the liquid to the gaseous phase without the effect of surface tension This combination of temperature and, pressure is known as the "critical point" of the Liquid.
