Enzyme production by solid-state fermentation on soybean meal: A comparative study of conventional and ultrasound-assisted extraction methods
(Wiley, Hoboken, 2019)
Protease, cellulase, and alpha-amylase producing Bacillus subtilis strain was cultivated by solid-state fermentation technique using soybean meal as a substrate. The aim of the present study was to establish a highly ...
Adsorption performances of branched aminated waste polyacrylonitrile fibers: experimental versus modelling study
(Desalination Publ, Hopkinton, 2019)
Synthesis of branched aminated waste polyacrylonitrile (PAN) fibers, realized in a three addition/amidation successive steps, was performed in order to obtain AS3-PAN adsorbent. Influence of various operating parameters ...
Improvement of the Textile Industry Wastewater Decolorization Process Using Capillary Microreactor Technology
(Springer International Publishing Ag, Cham, 2019)
Dyes are an important class of pollutants because large amounts are often found in the environment as a result of their extensive industrial use. Traditional wastewater treatment methods often lead to high energy costs, ...
Antibacterial activity of metal-containing clinoptilolite in natural seawater
(Desalination Publ, Hopkinton, 2019)
Antibacterial activity of a natural zeolite, clinoptilolite (Z), enriched with about 0.4-0.5 mmol of Ag (Ag-Z), Cu (Cu-Z) or Zn (Zn-Z) was tested toward two strains of Gram-negative bacteria - Escherichia coli and Acinetobacter ...
On the azo dyes derived from benzoic and cinnamic acids used as photosensitizers in dye-sensitized solar cells
(Scientific Technical Research Council Turkey-Tubitak, Ankara, 2019)
In order to get a better insight into the relationship between molecular structure and photovoltaic performance, six monoazo dye molecules containing benzoic and cinnamic acid moieties were synthesized and their photovoltaic ...
Continuous flow synthesis of some 6-and 1,6-substituted 3-cyano-4-methyl-2-pyridones
(Srpsko hemijsko društvo, Beograd, 2019)
In this study, six 6- and 1,6-substituted-3-cyano-4-methyl-2-pyridones were synthesized in a continuous flow microreactor system. The syntheses were realized at room temperature and the obtained results were compared to ...
Stimuli-Sensitive Hydrogel Based on N-Isopropylacrylamide and Itaconic Acid for Entrapment and Controlled Release of Candida rugosa Lipase under Mild Conditions
(Hindawi Ltd, London, 2014)
Stimuli responsive pH- and temperature-sensitive hydrogel drug delivery systems, as those based on N-isopropylacrylamide (NiPAAm) and itaconic acid (IA), have been attracting much of the attention of the scientific community ...
Assessing the pharmacological potential of selected xanthene derivatives / Određivanje farmakološke aktivnosti derivata ksantena
(Serbian Chemical Society, 2023)
A convenient and efficient approach toward the synthesis of seven aromatically substituted xanthendiones 1‒7 and one structurally-related xanthenone 8 through condensation of dimedone and the appropriate aromatic aldehyde ...
Simulated Body Fluids Prepared with Natural Buffers and System for Active pH Regulation
(Iranian Institute of Research and Development in Chemical Industries, 2022)
The current study focuses on creating an initial highly alkaline simulated body fluid whose pH can be decreased to a physiological range by adding CO2 (protein-free simulated body fluid) or a combination of CO2 and human ...
