This blog was created 2 years ago with the aim of spreading the knowledge on supercritical fluids. At the same time related subjects, such as sustainable development or green chemistry, have also been touched as these themes are close to the supercritical fluids because SFE (supercritical fluid extraction) is a "green chemistry" process.
I've tried to add something at least once a month, but news about supercritical fluids are not very common and I don't want to make this blog too much technical.
I still waiting some answer or question from readers and hope that sooner or later it would be some.
I would like to thank all the visitor from all around the world and hope to see you back again!

Supercritical solution for global warming...
An article about CO2 capture and storage has been published in Nature Geoscience recently [1]. The storage of the CO2 is said to be in supercritical state, however only the pressure is above the critical point and therefore the system is not fully supercritical but in a compressed liquid state [2].

Geological carbon storageEnjoy the article!

Storage of the carbon dioxide that is produced by burning fossil fuels is one way to avoid the damaging consequences of climate change. A range of observations suggests that geological carbon storage is much less risky than unabated carbon emissions to the atmosphere.

SCF-Ex ; cannabis & multiple sclerosis
A recent article states [1]:

Cannabis therapy has been considered an effective treatment for spasticity, although clinical reports of symptom reduction in multiple sclerosis (MS) describe mixed outcomes. Recently introduced therapies of combined delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) extracts have potential for symptom relief with the possibility of reducing intoxication and other side effects. Although several past reviews have suggested that cannabinoid therapy provides a therapeutic benefit for symptoms of MS, none have presented a methodical investigation of newer cannabinoid treatments in MS-related spasticity. The purpose of the present review was to systematically evaluate the effectiveness of combined THC and CBD extracts on MS-related spasticity in order to increase understanding of the treatment's potential effectiveness, safety and limitations.These compounds can be easely extracted by means of supercritical fluid extraction (SCF-Ex) with CO2.
We found evidence that combined THC and CBD extracts may provide therapeutic benefit for MS spasticity symptoms. Although some objective measures of spasticity noted improvement trends, there were no changes found to be significant in post-treatment assessments. However, subjective assessment of symptom relief did often show significant improvement post-treatment. Differences in assessment measures, reports of adverse events, and dosage levels are discussed.
