The unusual behavior observed in the coefficient of thermal expansion and specific heat capacity CrFeNi, CoCrNi, CoCrFeNi medium/high-entropy alloys is commonly referred to as K-state effect. It shown be independent Curie temperature, demonstrated by temperature-dependent magnetic moment measurements. alloy chosen for detailed characterization; potential reasons effect such texture, recrystallization, second-phase precipitation are ruled out. An examination electronic structure indicates...
Methylene Blue (MB) is a dye widely used in the industrial sector and human veterinary pharmacology. This dye, if improperly disposed of, can cause significant environmental impact due to its low biodegradability, as it stable complex substance. Additionally, may affect health generate highly toxic byproducts. Hence, purpose of this work assess removal efficiency MB from synthetic effluent using ionic flocculation process. Such process consists dissolution biodegradable anionic surfactant...
<title>Abstract</title> In the intricate realm of high and medium entropy alloys (HEAs/MEAs), elusive nature Chemical Short-Range Order (CSRO) has captivated researchers, creating intense debates on its impact material properties. Rooted in local arrangement atoms, CSRO's pivotal role shaping structural mechanical characteristics HEAs remains a subject fervent exploration. The challenges lie confirming quantifying CSRO, as detection proves exceptionally demanding, contributing to conflicting...
Abstract The present study aimed to evaluate the removal efficiency of two types cationic dyes different classes – methylene blue (MB) and malachite green (MG) from a synthetic effluent using calcium surfactant (CaSF) originated used frying soybean oil. Fourier Transform Infrared Spectroscopy (FTIR) spectra showed that functional groups on surface CaSF can form complexes or bonds with dye molecules and, consequently, promote their adsorption. adsorption kinetics studies indicated equilibrium...

Abstract High phosphate concentrations in water may disturb the ecological balance, deteriorate quality, cause eutrophication and affect smart sustainable use of human activities. With that mind, goal this work was to study adsorptive capacity pequi peel ash (PPA) its efficiency removal (PO 4 3− ) from aqueous solutions, while measuring kinetics, equilibrium thermodynamics process. The is fruit species Caryocar coriaceum WITTM widely found Cariri region, state Ceará, Brazil. processing...
