20.500.12556/DKUM-67283 Effects of ultrasound irradiation on the preparation of ethyl cellulose nanocapsules containing spirooxazine dye This article presents the influence of low frequency, high intensity ultrasonic irradiation on the characteristics (average size, polydispersity index) of ethyl cellulose nanocapsules encapsulating a photochromic dye. Photochromic nanocapsules were prepared by the emulsion-solvent evaporation method. The acoustic densities entering the system were systematically studied with respect to their abilities to modify and reduce the average sizes and polydispersity indexes of the nanocapsules. Scanning electron microscope, confocal laser microscope, and dynamic light scattering were utilised to characterise the structure, shape, size, and polydispersity of ethyl cellulose photochromic nanocapsules. We were able to tailor the size of the photochromic nanocapsules simply by varying the acoustic densities entering the system. At an acoustic density of 1.5 W/mL and 60 s of continuous irradiation, we were able to prepare an almost monodispersed population of the nanocapsules with an average size of 193 nm. encapsulation ethyl cellulose microcapsules nanocapsules kapsuliranje etil celulozne kapsule nanokapsule true false true Angleški jezik Slovenski jezik Znanstveno delo 2017-08-09 12:19:12 2017-08-09 12:20:11 2022-08-01 13:46:28 2019-07-11 16:15:07 2017 0 0 str. 1-8 Letn. 2017 Published 6 July 2017 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1687-4129 677.466.017:544.57 2562639 20690198 10.1155/2017/4864760 1687-4129 URN:SI:UM:DK:LM1KETGY Journal_of_Nanomaterials_2017_Volmajer_Valh_et_al._Effects_of_Ultrasound_Irradiation_on_the_Preparation_of_Ethyl_Cellulose_Nanocapsules.pdf Journal_of_Nanomaterials_2017_Volmajer_Valh_et_al._Effects_of_Ultrasound_Irradiation_on_the_Preparation_of_Ethyl_Cellulose_Nanocapsules.pdf 1 E72DFBBEFD0D430D99FF9145C7FB01C4 dc6bb7fb19840a3608a9173e2af0b4b539202a081ae84584d5c717c99239d597 7f854000-7c0e-11eb-bb7a-00155d0001ca 20.500.12556/dkum/c8d1a467-1a0b-4a4c-9c56-0a111b5ba584 https://dk.um.si/Dokument.php?lang=slv&id=115083 https://www.hindawi.com/journals/jnm/2017/4864760/ 1 https://dk.um.si/Dokument.php?lang=slv&id=115082 Fakulteta za strojništvo 0 0 0
