She was treated with a process called carboxytherapy that resulted in great improvement of the scars with minimal to no discomfort or down time. Carbon Dioxide (CO2) therapy was first introduced in France for cutaneous use.1 CO2 is a non-toxic gas that is naturally produced by cells as they undergo the process of metabolism. As CO2 accumulates in the tissues it induces dilatation of capillaries...

Neutral alpha-D-mannosidase from monkey brain was purified by Co2+-chelate affinity chromatography and immunoadsorbent affinity chromatography. The purified enzyme, with subunit Mr 45,000, was essentially homogeneous with only traces of two contaminant proteins as revealed by SDS/polyacrylamide-gel electrophoresis and AgNO3 staining. The purified enzyme, on preincubation with Co2+ at 37 degrees...

Mixed matrix membrane used to selective removal of CO2 was considered as an efficient solution to energy and environmental sustainability. In this study, a MMM that consists of amide functionalized porous coordination polymer filler (MIL-53-NH2) was successfully prepared, which sharply promotes the CO2/N2 selectivity from 44 (neat polymeric membrane) to 75. Remarkably, the positive effect of am...

We consider the control problem of a Variable Configuration CO2 Removal system, which exhibits a hybrid dynamical character due to various operating modes of the system. The objective of the control problem is to track a desired concentration profile of CO2 and O2 in a crew cabin while keeping their concentrations within permissible bounds. We present a novel adaptation of the model predictive ...

The role of carbon dioxide in global warming is one of the contemporary environmental issues and it is, therefore, necessary to have available technology to capture the released CO2 into the atmosphere. Amino acids have the same amine functionality as alkanolamines with similar behavior towards CO2 absorption. The solubility of carbon dioxide in potassium glycinate (KG) solutions with different...

Carbon removal certification may become a powerful instrument to accelerate decarbonization efforts. In Europe, its implementation is expected foster the deployment of Bioenergy with Capture and Storage (BECCS). Yet, large-scale adoption BECCS also limited by availability costly CO2 transportation infrastructure shared fossil-fueled emitters. this paper, we examine interactions between carbon a...

CO2 biofixation was investigated using tubular bioreactors (15 and 1.5 l) either in the presence of green algae Chlorella vulgaris or Nannochloropsis gaditana. The cultivation was carried out in the following conditions: temperature of 25 °C, inlet-CO2 of 4 and 8 vol%, and artificial light enhancing photosynthesis. Higher biofixation were observed in 8 vol% CO2 concentration for both microalgae...

The use of analogies and repeated feedback might help people learn about the dynamics of climate change. In this paper, we study the influence of repeated feedback on the control of a carbon-dioxide (CO2) concentration to a goal level in a Dynamic Climate Change Simulator (DCCS) using the “bathtub” analogy. DCCS is a simplification of the complex climate system into its essential elements: CO2 ...
