Experimental Determination of the Critical Value of the J-Integral that Refers to the HSLA Steel Welded Joint
(Strojarski Facultet, 2023)
Fracture mechanics, as a scientific discipline dealing with the study of cracks in welded structures, has defined parameters and introduced new test methods in order to better determine the tendency to crack growth, critical ...
The study of composition-properties relationships for composite hydrogels based on poly(methacrylic acid) and high concentrations of MFI zeolite
(Elsevier, 2023)
High concentrations of hydrophobic MFI zeolite (26.0–51.3 wt%) were successfully embedded in poly(methacrylic acid) (PMAA) network in simple, one-pot synthesis of PMAA-MFI composite hydrogels. The effects of zeolite ...
Physico-chemical, structural, and adsorption properties of amino-modified starch derivatives for the removal of (in)organic pollutants from aqueous solutions
(International Journal of Biological Macromolecules, 2023)
In this study, an environmentally sustainable process of crystal violet, congo red, methylene
blue, brilliant green, Pb2+, Cd2+, and Zn2+ ions adsorption from aqueous solutions onto aminomodified starch derivatives was ...
INFLUENCE OF ELECTRODEPOSITION REGIME AND Sn:Pd RATIOS IN Sn-Pd ELECTROCATALYSTS ON ETHANOL OXIDATION REACTION / ВЛИЈАНИЕ НА РЕЖИМОТ НА ЕЛЕКТРОДЕПОЗИЦИЈАТА И НА ОДНОСИТЕ НА Sn:Pd ВО Sn-Pd-ЕЛЕКТРОКАТАЛИЗАТОРИТЕ ВРЗ ОКСИДАЦИЈАТА НА ЕТАНОЛОТ
(Society of Chemists and Technologists of Macedonia, 2023)
A series of bimetallic Sn-Pd catalysts were prepared by a template-free two step electrodeposition method. According to this method, Sn was electrodeposited firstly in potentiostatic or galvanostatic regime on Cu electrodes ...
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. ...
Predicting liquid chromatography−electrospray ionization/mass spectrometry signal from the structure of model compounds and experimental factors; case study of aripiprazole and its impurities
(Elsevier B.V., 2023)
A priori estimation of analyte response is crucial for the efficient development of liquid chromatography–electrospray ionization/mass spectrometry (LC–ESI/MS) methods, but remains a demanding task given the lack of knowledge ...
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 ...
Optimization of Enzymatic Desizing and Scouring of Cotton Fabric by Response Surface Methodology
(Publishing House of the Romanian Academy, 2023)
The study aimed to estimate the influence of temperature, time, and ultrasound application during desizing and scouring of cotton with α-amylase and pectinase, respectively, on the weight loss, breaking force and color ...
Obtaining Polysaccharide-Based Fabrics with Improved Moisture Sorption and Dye Adsorption Properties
(MDPI, 2023)
Raw jute fabric was treated with 0.5, 1.0, or 2.0% chitosan solution to improve its sorption
properties (evaluated through the moisture sorption and adsorption of textile dye Reactive Orange 16 (RO 16)), which are essential ...
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 ...
