Screening Design of Experiment Applied to Dispersive Liquid-Liquid Microextraction of UV Filters from Water
(The Eurasia Proceedings of Science Technology Engineering and Mathematics 11, 2020)
A Plackett-Burman factorial design (PBD) has been used for the optimization of dispersive liquidliquid microextraction (DLLME) of UV filters from water. The experimental procedure included a DLLME
sample preparation prior ...
Immobilization of Candida antarctica lipase B onto modified silica nanoparticles and its application for the synthesis of l-ascorbyl oleate
(University of Novi Sad, Institute of Food Technology, 2016)
Lipases immobilized onto nonporous fumed silica nanoparticles (FNS) proved to be suitable catalysts for the various commercially important esters synthesis. This inert hydrophilic material is usually modified by different ...

Karakterizacija liofilizovanih ekstrakata majčine dušice (thymus serpyllum l.) I njihova antioksidativna aktivnost
(Faculty of Technology, Zvornik, 2017)
Budući da je većinu aktivnih komponenata biljaka nemoguće sintetisati u
laboratoriji, najbolja opcija je njihova ekstrakcija iz prirodnih izvora. U
datom eksperimentu, korišćena je herba majčine dušice (Thymus serpyllum)
i ...
Ekstrakcija odabranih lekova na višeslojnim ugljeničnim nanocevima / Extraction of selected pharmaceuticals on multiwalled carbon nanotubes
