The process is, however, relatively expensive due to high cost of liquid carbon dioxide. The critical temperature of carbon dioxide is 31°C and the critical pressure just over 1000 psi. Critical carbon dioxide is an excellent solvent for essential oils. Due to the relatively low temperature of...
The meaning of CARBON OFFSET is an action or activity (such as the planting of trees or carbon sequestration) that compensates for the emission of carbon dioxide or other greenhouse gases to the atmosphere; also : a quantifiable amount of such an activit
The level of carbon dioxide in the atmosphere has increased by 12% in the last 100 years, mainly due to the burning of fossil fuels and the destruction of rain forests. The increased level of carbon dioxide is the main cause for an average increase of 0.5℃ in the mean global temperature...
reduce the meanairway pressureduring controlled ventilation have been suggested but are not commonly used.88 Mixing of the exhaled gases is required if carbon dioxide production and physiologic dead space are to be measured. Standard physiologic testing usually collects all the exhaled gas for several...
A low-carbon lifestyle means cutting carbon dioxide emissions and living a life characterized by low-energy use, low consumption and low spending. This way of living is being accepted by a growing number of average people in China. Before low-carbon became a popular word here, some environment...
Gas permeation through glassy polymer membranes with relatively low glass-transition temperature When the glass-transition temperature of the polymer is not so much higher than the experimental temperature, the pressuredependence of the mean permeabili...

Carbon dioxide is a stable and inert molecule that needs a large amount of energy for its splitting which means low energy conversion efficiency. Plasma (ionized gas) is an active medium containing different species including neutral species, ions, electrons, excited species, etc. The ionized speci...
With the increase in global energy consumption and carbon dioxide emissions, the low-carbon economy and low-carbon development have become the focus of attention all over the world [2]. As a populous and manufacturing country, China should take corresponding responsibilities. All the provinces of ...
Climate positivemeans that an activity goes beyond achieving net zero carbon emissions to actually create an environmental benefit by removing additional carbon dioxide from the atmosphere. Carbon negativemeans the same thing as “climate positive.” ...
Carbon dioxide is the most commonly used supercritical fluid. The critical properties of carbon dioxide are respectively low (Tc = 304.2 K and Pc = 7.38 MPa) and it is non-toxic, non-flammable, non-explosive and readily available at low cost [1], [2]. In this work, the solubility of...
