Five different objective functions were studied with the purpose of analyzing their performance for parameters estimation of vapor-liquid equilibrium models for a series of 13 non-polar and 13 polar asymmetric binary mix...

This study investigates how different carbon-containing absorbents affect the transient phase change expansion of liquid oxygen. Specifically, we prepared 3 types of liquid oxygen charges with varying carbon contents (0,...

"This paper proposes a control strategy that mitigates the cross contamination of H2 and O2 in a high-pressure alkaline electrolyzer, which consequently increases the supplied gases purity. In order to reduce the diffusi...

"This paper proposes two control strategies that mitigate the cross contamination of H2 and O2 in a high-pressure alkaline electrolyzer, which consequently increases the supplied gases purity: one based on a decoupled PI...

In this paper, we calculate solvation free energies of several compounds in ionic liquids. These free energies are used to compute properties such as Henry's law constants and activity coefficients, generally required in...

OBJETIVOS: Diagnosticar bioquimicamente o estado nutricional de vitamina E de lactantes por meio da análise do alfa-tocoferol no soro e no colostro, verificar sua associação com variáveis maternas e determinar a prev...

This study investigates the impact of fiber composition and fabric structure on the liquid absorption and retention performance during pressure of weft-knitted fabrics designed for reusable incontinence products. Twelve ...

Abstract Accumulation of plastic waste presents a global environmental crisis, posing severe threats to ecosystems. Depolymerization offers a promising route for closed-loop recycling of plastic waste. Nevertheless, depo...

As green solvents, ionic liquids (ILs) were highly effective for CO2 absorption. However, lots of possible anion–cation combinations made experimental measurement of CO2 solubility for each IL time- and resource-intens...

This manuscript focuses on the application of imidazolium-based ionic liquids (ILs) 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIM]+[PF6]−) and 1-butyl-3-methylimidazolium bis(trifluoromethane)sulfonimide ([BMI...

Abstract A three-dimensional numerical model based on the volume-of-fluid (VOF) method is typically preferred for studying high-current gas metal arc welding (GMAW) metal transfer mechanism and then controlling it. It is...

Abstract Graphene has superhigh thermal conductivity up to 5000 W/(m·K), extremely thin thickness, superhigh mechanical strength and nano-lamellar structure with low interlayer shear strength, making it possess great po...

ABSTRACT: Introduction: The links between oral health and female ageing are poorly understood, but many changes occur in the oral cavity of menopausal women that affect quality of life, and few current oral health inter...

Abstract Background A sustainable and stability-indicating reversed-phase high-pressure liquid chromatography (RP-HPLC) method has been developed for the simultaneous estimation of chlorthalidone (CHL), Amlodipine (AML),...

Water build-up has continued to be one of the leading causes of performance variability and loss of durability in proton exchange membrane fuel cells (PEMFCs), especially at the high current density and transient operati...

To enhance the total output energy and power of energetic materials, plasma that generated by electrically exploded metal wires was employed to initiate the detonation of energetic materials, thereby achieving the couple...

Abstract Wireless bioelectronics demand transduction strategies that are simultaneously sensitive, noise-resilient, and biologically safe. Conventional wireless sensors typically rely on dielectric capacitors with inhere...

Metal–organic frameworks (MOFs) have emerged as promising materials for atmospheric water harvesting (AWH). Large-pore MOFs provide high water capacity, but their significant hysteresis between sorption and desorption ...

The phase equilibria of binary CO2 + n-alkane mixtures have been studied by an important number of authors, both experimentally and using different types of thermodynamic models. Modeling studies of the phase behavior of...

Abstract The reservoirs in the western South China Sea oilfield are characterized by low permeability, poor pore connectivity, high laminated content, severe pollution, and prominent interlayer contradictions. For this r...

Abstract Background Myxomatous mitral valve disease (MMVD) is frequently diagnosed in small breed dogs. Pimobendan oral solution has been developed to improve dosing accuracy in small and toy breed dogs. Hypothesis/Objec...

The article addresses the urgent issue of the transformation of household financial behavior during a period of economic instability caused by a combination of war-related risks, inflationary pressures, and structural ch...

In marine environments, the increased drag force on vehicles impedes their speed underwater, leading to high energy consumption and reduced vehicle efficiency. Superhydrophobic coatings have gained remarkable attention r...

In this paper, an H∞ control strategy is implemented in a prototype alkaline electrolyzer to maintain equalized the liquid levels in the separations chambers while following a pressure reference. The aim is to minimize...
