Modified simultaneous saccharification and fermentation for the production of bioethanol from highly concentrated raw corn starch
(Elsevier Ltd, 2023)
Bioethanol is one of the main bio-based molecules produced mainly from sugar cane, molasses and corn. Its environmental advantages allow it to be considered as safe and the cleanest fuel alternative. Starch is a widespread ...
Sonophotocatalytic degradation of dye CI Acid Orange 7 by TiO2 and Ag nanoparticles immobilized on corona pretreated polypropylene non-woven fabric
(Elsevier, 2015)
This study discusses the possibility of using corona pre-treated polypropylene (PP) non-woven fabric as a support for immobilization of colloidal TiO2 and Ag nanoparticles in order to remove dye C.I. Acid Orange 7 from ...
Coordination preferences of NNO and NNS Schiff base ligands with Co(III) complexes: Synthesis, characterization and DFT calculation
(Elsevier, 2022)
Two Co(III) complexes with condensation product of thiosemicarbazide and 2-acetylthiazole (HL1 ligand, (E)-2-(1-(thiazol-2-yl)ethylidene)hydrazine-1-carbothioamide) and the condensation product of 2-acetylpyridine and ...
Effects of waste sulfur content on properties of self-compacting concrete
(Consejo Superior de Investigaciones Cientificas - CSIC, 2020)
Self-compacting concrete (SCC) contains fine mineral fillers such as limestone powder. The idea of this study was to partially replace limestone with waste sulfur since it is hydrophobic, insoluble in water and therefore ...
Kinetic modeling and optimization of sunflower oil methanolysis catalyzed by spherically-shaped CaO/gamma-Al2O3 catalyst
(Oxford : Pergamon-Elsevier Science Ltd, 2018)
Kinetic modeling and optimization of sunflower oil methanolysis catalyzed by spherically-shaped CaO/gamma-Al2O3 particles were conducted in batch stirred and packed-bed tubular reactors at 60 degrees C. The proposed ...
Production of raw-starch-digesting alpha-amylase isoform from Bacillus sp under solid-state fermentation and biochemical characterization
(Springer, New York, 2014)
alpha-Amylase production by solid-state fermentation of different Bacillus sp. was studied previously on different fermentation media. However, no study has been reported on the influence of selected media on expression ...
Adsorption kinetics of polyethersulfone membrane-supported hydrogels
(Hopkinton : Desalination Publications, 2018)
This study presents the route for preparation of the membrane-supporting materials with good mechanical behavior and adsorption properties that provide functionality and are easy to use in various environments. Polyethersulfone ...
Synthesis and properties of nano-hydroxyapatite/poly (methacrylic acid) composite hydrogels / Uticaj neutralizacije na svojstva poroznih hidrogelova na bazi hidroksiapatita i poli(metakrilne kiseline) sintetisanih slobodno-radikalskom polimerizacijom
(Beograd : Savez inženjera i tehničara Srbije, 2018)
Goals. The goal of this study was a development of biocompatible composite hydrogels, structurally similar to native bone tissue, by incorporation of ~60 wt % of calcium hydroxyapatite (HA) into a matrix of hydrogels. Also, ...
Modeling and optimization of sunflower oil methanolysis over quicklime bits in a packed bed tubular reactor using the response surface methodology
(Oxford : Pergamon-Elsevier Science Ltd, 2016)
The effect of the residence time (i.e. liquid flow rate through the reactor), methanol-to-oil molar ratio and reaction temperature on the fatty acid methyl esters (FAMEs) content at the output of a continuous packed bed ...
Chemical modification of chloroperoxidase for enhanced stability and activity
(Elsevier Sci Ltd, Oxford, 2014)
Chloroperoxidase from Caldariomyces fumago (CPO, EC 1.11.1.10) is one of the most interesting enzymes from the group of heme peroxidases and has been extensively applied in synthetic processes. Nevertheless, the practical ...
