SUPERCRITICAL CO2 FOAMING OF PLLA WITH LIQUID CO2-PHILIC CELL NUCLEATORS Çulhacıoğlu, Yağmur; Hasırcı, Nesrin; Dilek Hacıhabiboğlu, Çerağ (null; 2018-09-01) There is an increasing trend towards replacing synthetic polymers with their natural counterparts and applying environmentally friendly processing techniques [1]. For both industrial and biomedical applications, natural originated biodegradable polymers are intensely studied due to their environmentally benign and biocompatible nature. Supercritical carbon dioxide (scCO2)processing of polymers is a green approach since it reduces or eliminates the use of organic solvents and thus emissions of volatile organ...

Supercritical processing of CO2-philic polyhedral oligomeric silsesquioxane (POSS)-poly(L-lactic acid) composites Novendra, Novendra; Hasırcı, Nesrin; Dilek Hacıhabiboğlu, Çerağ (2016-11-01) High molecular weight and semicrystalline poly(L-lactic acid) (P(L)LA) films were processed with supercritical carbon dioxide (scCO(2)) for environmentally friendly formation of porous films. The polymeric matrix was processed with supercritical CO2 and the system was rapidly depressurized to cause supersaturation of the polymer, leading nucleation and growth of the pores in the matrix. Even though saturation temperatures close to the melting points of the polymers are required to form porous matrices of se...
Supercritical Fluid Processing for the Recovery of Biactive Compounds from Food Industry By-Products Yener, Meryem Esra (Springer, 2015-01-01) By-products of food industry, especially wine industry, fruit and vegetable processing industry, oil industry, milling industry, seafood processing industry are rich in bioactive compounds. These compounds are mainly polyunsaturated fatty acids (PUFAs), tocopherols, phytosterols, squalene, carotenoids and polyphenols. Supercritical carbon dioxide (SCCO2) extraction of specialty oils rich in bioactive compounds, fractionation of specialty oils or by-products to enrich the bioactive compounds, supercritical f...
Supercritical fluid extraction and temperature-programmed desorption of phenol and its oxidative coupling products from activated carbon HUMAYUN, RASHINA; Karakaş, Gürkan; Dahlstrom, PR; OZKAN, UMIT S; TOMASKO, DAVID L (1998-08-01) Activated carbon remains one of the most economical adsorbents for the removal of contaminants from water. In particular, activated carbon is known to have an extremely high affinity for phenol and its derivatives. This has been shown to be the result of a catalytic process wherein activated carbon catalyzes the oxidative coupling reactions of phenol in aqueous solution when molecular oxygen is present. These reactions are believed to be the source, of the difficulty of regenerating activated carbon loaded ...
