Innovation and technology are seen today as key points in the transition to a greener more sustainable economy. In this sense, development of new processes able result reduced emissions levels CO2 atmosphere has been considered essential support and, at same time, promote economic growth. Several techno-economic life cycle assessment studies have shown promising data when sugars derived from li...

Aromatic units bring special features to supramolecular receptors when the challenge of binding and release CO2 is being addressed. Recent examples arising from calixarenes, pillararenes cyclophanes are discussed in this review. The abilities these systems spatially organize metal coordination, hydrogen bonding or hydrophobic interactions for purpose pointed out. Consequences sensing catalytic ...

Rising atmospheric CO2 is increasing the availability of dissolved CO2 in the ocean relative to HCO3 (-). Currently, many marine primary producers use HCO3 (-) for photosynthesis, but this is energetically costly. Increasing passive CO2 uptake relative to HCO3 (-) pathways could provide energy savings, leading to increased productivity and growth of marine plants. Inorganic carbon-uptake mechan...

Testing whether and how subordinate individuals differ from dominants in the utilization of enriched CO2 atmospheres is important for understanding future stand and community structure. We hypothesized that subordinate and dominant Ambrosia artemisiifolia L. (Asteraceae) (common ragweed) plants growing in dense stands would not equally acquire or utilize carbon gains from CO2-enrichment, and th...

Acclimation of photosynthesis to elevated atmospheric carbon dioxide concentration was tested in lines of soybean (Glycine max) that differed by single genes that altered either the capacity to nodulate or growth habit (determinate or indeterminate growth). Both genetic changes provided, within a uniform genetic background, a test of the “source–sink” hypothesis that down-regulation of photosyn...

BACKGROUND In patients with acute respiratory failure, gas exchange is impaired due to the accumulation of fluid in the lung airspaces. This life-threatening syndrome is treated with mechanical ventilation, which is adjusted to maintain gas exchange, but can be associated with the accumulation of carbon dioxide in the lung. Carbon dioxide (CO2) is a by-product of cellular energy utilization and...

Intensive algal cultivation usually requires a high flux of dissolved inorganic carbon (Ci) to support productivity, particularly for high density algal cultures. Carbon dioxide (CO2) enrichment can be used to overcome Ci limitation and enhance productivity of algae in intensive culture, however, it is unclear whether algal species with the ability to utilise bicarbonate (HCO3 (-)) as a carbon ...

The partial substitution of O2 with CO2 in steelmaking process is an important technology to reduce emission and recycle. In order improve CO2–O2 decarburization utilization, the kinetics Fe–C melt mixed gas have been studied using 13CO2–18O2 dual isotope tracing method established kinetic model. results show that less than 40% oxygen partially replaced by CO2, which improves utilization involv...

Since solid oxide fuel cells (SOFC) produce electricity with high energy conversion efficiency, and chemical looping combustion (CLC) is a process for fuel conversion with inherent CO2 separation, a novel combined cycle integrating coal gasification, solid oxide fuel cell, and chemical looping combustion was configured and analyzed. A thermodynamic analysis based on energy and exergy was perfor...
