Catalytic activity of novel thermoplastic/cellulose-Au nanocomposites prepared by cryomilling
(TUBITAK, 2020)Due to environmental concerns, increasing attention has been focused on the application and preparation of biobased polymers and their blends. In this study, cellulose, the most spread biopolymer on Earth, was used in the ... -
Formation and characterization of mechanochemically generated free lignin radicals from olive seeds
(Scientific and Technical Research Council of Turkey - TUBITAK,Turkiye Bilimsel ve Teknik Arastirma Kurumu, 2021-04-28)In this study, formation and quantification of mechanochemically generated free radicals of lignin were evaluated after the extraction of lignin from olive seeds and detailed lignin characterization was performed. Lignin ... -
Mechanochemical radical formation in cellulose ball milling and production of cellulose-metal nanoparticles composites
(Bilkent University, 2017-12)Cellulose is the most abundant biopolymer in nature, which contains linear chains of repeating D-glucose molecules connected by 𝛽-1,4-glycosidic linkages. Over the past decades, due to growing interest in sustainability ... -
The morphological changes upon cryomilling of cellulose and concurrent generation of mechanoradicals
(Elsevier, 2019)With mechanical input, chemical bonds in polymers can be broken. Recently, it was shown that reactive ends formed by homolytic cleavage, so-called mechanoradicals, can be used in driving further chemical reactions or in ... -
Towards mechanochemical generation of singlet oxygen
(Bilkent University, 2018-12)Singlet oxygen is a short-lived reactive species which is involved a number of biochemical processes and implicated as the primary photo-generated cytotoxic agent in photodynamic therapy (PDT) of cancer. Precise chemical ... -
Ultrasonication for environmentally friendly preparation of antimicrobial and catalytically active nanocomposites of cellulosic textiles
(American Chemical Society, 2020)The global demand for sustainable and functional fibers and textile materials is increasing with the pressure to limit the synthetic petroleum-based counterparts. In this study, we use ultrasonication for the preparation ...
