Fractionated CO2 laser skin rejuvenation
Dermatologic Therapy, 2011Fractional photothermolysis has been reported in the literature to improve both the pigmentary and textural changes associated with photoaging. The objective of the study was to review the literature of non-ablative fractional laser (NAFL) and ablative fractional laser (AFL) resurfacing for the treatment of photoaging.

Rose concrete fractionation by supercritical CO2
The Journal of Supercritical Fluids, 1996Abstract Supercritical CO2 extraction was used to post-process a solid rose extract produced by liquid solvent extraction. Single step supercritical extraction at 80 bar, 40 °C, and a two-stage separation procedure at 80 bar and −16 °C and at 15 bar and 0 °C, were the optimum process conditions to produce a volatile rose oil with an overall 2-phenyl ...

Supercritical CO2 fractionation of jasmine concrete
The Journal of Supercritical Fluids, 1995Abstract Jasmine fragrance is usually produced by hexane extraction. The extraction product called a “concrete,” undergoes further processing to separate fragrance compounds from undesired coextractives such as paraffins and fatty acid methyl esters. This study reports supercritical CO 2 fractionation of jasmine concrete to avoid thermal degradation

Fractionation of glycerol acetates with supercritical CO2
The Journal of Supercritical Fluids, 2019Abstract Glycerol acetates are sustainable products that exhibit several industrial applications. These compounds are traditionally synthesized by the esterification of glycerol with acetic acid, and their fractionation is key to isolate high value-added products.

Mathematical modelling of supercritical CO2 fractionation of flower concretes
Chemical Engineering Science, 1996Abstract A new process to obtain volatile oils by fractionation of flower concretes by supercritical fluid extraction was successfully tested for rose and tuberose. Chemical analysis indicated that the quality of the product obtained by means of this technique is superior to that of the corresponding product obtained by the traditional techniques ...

Fractionation of fish oils using supercritical CO2 and CO2+ethanol mixtures
The Journal of Supercritical Fluids, 2000Abstract This work reports the countercurrent extraction and fractionation of a range of crude fish oils using supercritical carbon dioxide and carbon dioxide+ethanol mixtures. Vitamin A palmitate was extracted from model Cod liver oil/vitamin mixtures using pure CO2. The separation factor was low, due to similar solubilities of the vitamin ester and

Fractional-Flow Theory of CO2 Foam Displacements with Surfactant Dissolved in the CO2
IOR 2009 - 15th European Symposium on Improved Oil Recovery, 2009A foam process with surfactant dissolved in supercritical CO2 has the advantage that injection of CO2, once begun, need never be interrupted for surfactant injection in water. In addition, CO2 can carry surfactant to layers that may not be swept by an aqueous surfactant slug. CO2 carries the surfactant and forms foam with water in the formation.

Significant alleviation of Darier's disease with fractional CO2 laser
Journal of Cosmetic and Laser Therapy, 2014Darier's disease (DD) is a dominantly inherited genodermatosis with highly variable expression. It is characterized by symmetrical hyperkeratotic papules affecting seborrheic areas and extremities. The existence of unsightly lesions could lead to discomfort and social handicap.

The Use of CO2 Fractional Photothermolysis for the Treatment of Burn Scars
Journal of Burn Care & Research, 2016A recent advancement in the treatment of burn scars has been the use of the carbon dioxide (CO2) laser to perform fractional photothermolysis. In this analysis, we describe our results and patient-reported outcomes with the use of fractional CO2 laser for the treatment of burn-related scarring.
