Ultrasound-assisted extraction of essential and toxic elements from pepper in different ripening stages using Box–Behnken design
(John Wiley and Sons Inc., 2022)
The influence of extraction parameters on the ultrasonically assisted extraction (UAE) of K, Na, Ca, Mg, Zn, Cu, Fe, Mn, Cr, Se, Mo, Li, Al, B, Pb, Hg, Cd, As, and Ni was studied to determine the conditions when a minimum ...
Hydrolysis of soft wheat flour: Enhanced functional properties and the effect of starch on allergenicity reduction
(Journal of Food Processing and Preservation, 2022)
The possibility to utilize Alcalase to hydrolyze soft wheat flour (SWF) containing high concentration of solids (i.e. starch) and the effect of its presence was investigated. At a degree of hydrolysis of 23.49% +/- 0.64%, ...
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. ...
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 ...
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 ...
Green corrosion inhibitors of steel based on peptides and their constituents: a combination of experimental and computational approach
(Springer Science and Business Media Deutschland GmbH, 2023)
In this work, six groups of non-toxic compounds were tested as inhibitors for mild steel in 1 M HCl solution: glycine (Gly), glutamic acid (Glu), cysteine (Cys), a mixture of three amino acids glycine, glutamic acid, and ...
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 ...
Thermo-mechanical analysis of linear welding stage in friction stir welding Influence of Welding Parameters
(VINČA Institute of Nuclear Sciences, 2022)
The influence of friction stir welding parameters on thermo-mechanical behavior of the material during welding is analyzed. An aluminum alloy is considered (Al 2024 T351), and different rotating and welding speeds are ...
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 ...
Processing of Data Obtained by the Testing of Steel under Low Cyclic Fatigue (Part I)
(University of Zagreb Faculty of Mechanical Engineering and Naval Architecture, 2022)
The design of mechanical components exposed to fatigue load, at a low number of cycles, requires knowledge of the behaviour of the material under the impact of variable load in conditions of controlled strain when cyclic ...
