Beech sawdust based adsorbents for solid-phase extraction of pesticides and pharmaceuticals
(Serbian Chemical Society, 2022)
Carbonaceous solid-phase extraction (SPE) sorbent, efficient in isol-ation and enrichment of multiclass pesticides and pharmaceuticals from water, was synthesized starting from cheap waste beech sawdust and using KOH as ...
Influence of boron doping on characteristics of glucose-based hydrothermal carbons
(Journal of the Serbian Chemical Society, 2022)
In this study, the influence of boron doping on structural and surface properties of carbon material synthesized by a hydrothermal method was investigated, and the obtained results were compared with the previously published ...
Electrochemical stability of gold complex based on mercaptotriazole at optimal condition
(Springer Science and Business Media Deutschland GmbH, 2022)
This study investigates the electrochemical stability of the gold complex based on mercaptotriazole at an optimum pH of nine in the electrolyte with a gold concentration of 2.5 g dm−3. The stability of the complex was ...
Cellulases: From Lignocellulosic Biomass to Improved Production
(MDPI, 2023)
Cellulases are enzymes that are attracting worldwide attention because of their ability to degrade cellulose in the lignocellulosic biomass and transform it into highly demanded bioethanol. The enzymatic hydrolysis of ...
CHARACTERIZATION OF TEA AQUEOUS EXTRACTS AND THEIR UTILIZATION FOR DYEING AND FUNCTIONALIZING FABRICS OF DIFFERENT CHEMICAL COMPOSITIONS
(Society of Chemists and Technologists of Macedonia, 2023)
Green, black, rooibos, and hibiscus tea (GT, BT, RT, and HT) aqueous extracts were prepared and
characterized in terms of total flavonoids (TFC) and total phenolic (TPC) contents and antioxidant and antimicrobial activities. ...
Differences in attitudes of operators and managers on risk management of pressure equipment
(Taylor and Francis Ltd., 2022)
Objectives. Previous research indicates that models for risk assessment of pressure equipment have not sufficiently or adequately integrated indicators of human factors and organizational factors. Methods. The goal of this ...
The synthesis, characterization, antioxidant and antimicrobial activity of some novel amides of the esters of substituted 1,4-dihydropyridines / Синтеза, карактеризација, антиоксидативна и антимикробна активност некиx нових амида естара 1,4-дихидропиридина
(Serbian Chemical Society, 2024)
The esters of substituted 1,4-dihydropyirdines (1,4-DHP) are formed in the reaction of an appropriate aldehyde and ethyl acetoacetate in the presence of concentrated water solution of ammonia. The esters form the amides ...
Dispersive liquid–liquid microextraction and Monte Carlo simulation of margin of safety for octocrylene, EHMC, 2ES, and homosalate in sunscreens
(John Wiley and Sons Ltd., 2023)
Dispersive liquid–liquid microextraction (DLLME) using a floating organic drop has been optimized and used for the sample preparation of four commonly used ultraviolet filter (UVF) substances in sunscreens. Plackett–Burman ...
Disparate soil textures as a native medium for As(V) and Pb(II) separation from aqueous systems
(Desalination Publications, 2022)
This study investigated the use of different natural raw soil materials as low-cost adsorbents for
the removal to remove As(V) and Pb(II) from aqueous systems. It deals with the effect of different soil textures, sandy ...
Xylanase Production by Solid-State Fermentation for the Extraction of Xylooligosaccharides from Soybean Hulls
(University of Zagreb, 2023)
Research background. The development of a novel process for the production of xy-looligosaccharides (XOS) based on the 4R concept is made possible by the integration of numerous techniques, especially enzymatic modification ...
