Solid-phase extraction (SPE) of eleven ultraviolet filters (UVFs): benzophenone-1 (BP-1); benzophenone-3 (BP-3); benzophenone-4 (BP-4); isoamyl p-methoxycinnamate (IAMC), homosalate (HMS); 4-hydroxybenzophenone (4-HB); ...
Greenness of dispersive microextraction using molecularly imprinted polymers
(Walter de Gruyter, 2024)
Molecularly imprinted polymers (MIPs) as materials with determined levels of selectivity and specificity for designated analytes have recently gained much attention in various application fields. However, with the growing ...
Exploring the supramolecular profile of 5-phenylhydantoins
(Royal Society of Chemistry, 2023)
The present study describes representative examples of supramolecular arrangement of 5-phenylhydantoins achieved through various N-H⋯O hydrogen-bonding patterns. Four derivatives, 5-ethyl-5-(4-methylphenyl)hydantoin (1) ...
Recovering the Soybean Hulls after Peroxidase Extraction and Their Application as Adsorbent for Metal Ions and Dyes
(Hindawi Limited, 2023)
This study is aimed at extending the soybean hulls' lifetime by their utilization as an adsorbent for metal ions (Cd2+ and Cu2+) and dyes (Reactive Yellow 39 (RY 39) and Acid Blue 225 (AB 225)). ATR-FTIR spectroscopy, ...
The Effects of Irrigation, Topping, and Interrow Spacing on the Yield and Quality of Hemp (Cannabis sativa L.) Fibers in Temperate Climatic Conditions
(MDPI, 2022)
The study was aimed at determining the most suitable irrigation schedule program for hemp grown for fibers by using evaporation from the free water surface (Eo), measured by a Class A pan and related crop plant coefficient ...
Berries Pomace Valorization: From Waste to Potent Antioxidants and Emerging Skin Prebiotics
(Taylor and Francis Ltd., 2024)
Fruit pomaces are agro-industrial by-products obtained in large quantities by the juice production industry, hence their reutilization is a suitable way to minimize environmental impact by transforming them into different ...
Microencapsulation of probiotic starter culture in protein–carbohydrate carriers using spray and freeze-drying processes: Implementation in whey-based beverages
(Elsevier Ltd., 2022)
The production of functional beverages has gained more attention because of growing consumers' interest in personal health. The process of carrier production and characterization of a novel type of protein-carbohydrate ...
Heterofunctional epoxy support development for immobilization of fructosyltransferase from Pectinex® Ultra SP-L: batch and continuous production of fructo-oligosaccharides
(Royal Society of Chemistry, 2022)
In this study, a heterofunctional carrier was obtained by modification of a macroporous polystyrene ion exchange resin with primary amino groups (Purolite® A109) with epichlorohydrin, in view of achieving covalent ...
Determination of Mechanical Properties of Epoxy Composite Materials Reinforced with Silicate Nanofillers Using Digital Image Correlation (DIC)
(MDPI, 2022)
In this study, silicate nanofillers; dicalcium silicate, magnesium silicate, tricalcium silicate, and wollastonite; were synthesized using four different methods and incorporated into the epoxy resin to improve its mechanical ...
