    Thermodynamically-Consistent NVT Flash Calculation and Thermodynamics-Informed Neural Network (TINN) Accelerating Phase Equilibrium Estimates

    Tao Zhang1, Hua Bai2, Shuyu Sun1,*

    The International Conference on Computational & Experimental Engineering and Sciences, Vol.26, No.2, pp. 1-2, 2023, DOI:10.32604/icces.2023.09050

    Abstract The current well-developed and widely-recognized models describing interfacial tension are explicit functions of volume, temperature and moles so that it is more straightforward to compute the derivative of interfacial tension with respect to volume than pressure. We will propose a novel and comprehensive multicomponent multi-phase flow simulation algorithms based on diffuse interface models. In order to improve the robustness and reliability, realistic EoSs, represented by Peng-Robinson equation of states, are selected to formulate the thermodynamic correlations and an NVT-based flash calculation scheme is used to control the phase behaviors [1]. Compared to the minimized Gibbs… More >

    A Novel Method for Heat Exchange Evaluation in EV

    Mohammad Saraireh*

    Intelligent Automation & Soft Computing, Vol.36, No.1, pp. 57-70, 2023, DOI:10.32604/iasc.2023.032050

    Abstract With the growing global energy and environmental problems, electric vehicles that are both environmentally friendly and cost effective have seen rapid growth. An electrified vehicle’s effective thermal management must include all of the vehicle’s systems. However, optimizing the thermal behavior of each component is insufficient. A lithium-ion battery’s operating temperature has a significant impact on its performance. When working at low temperatures, the internal resistance of lithium-ion batteries increases, the available energy and power of the system decreases, and lithium precipitation caused by low-temperature charging may cause safety issues; high-temperature operation and temperature inconsistency between… More >

    Cell bioenergetics: Simple logics, complex solution

    LUIS S. MAYORGA*

    BIOCELL, Vol.46, No.10, pp. 2217-2220, 2022, DOI:10.32604/biocell.2022.020806

    Abstract Cells are open systems that exchange energy and molecules with their environment. As any material system, they perform all the complex activities required for homeostasis and reproduction, obeying the thermodynamic laws. This viewpoint will argue that the basic logic governing the energy flux required to preserve cell organization and function is simple: to decrease the activation energy (Ea) of specific processes. Almost none of the possible chemical reactions and energy transformations inside a cell occur at a measurable speed at room or body temperature. Enzymes or other macromolecular structures speed up particular transformations by decreasing More >

    Mohammad Saraireh1,*, A. M. Maqableh2, Manar Jaradat3, Omar A. Saraereh4

    CMC-Computers, Materials & Continua, Vol.73, No.1, pp. 2115-2133, 2022, DOI:10.32604/cmc.2022.029978

    Abstract The growing need for renewable energy and zero carbon dioxide emissions has fueled the development of thermoelectric generators with improved power generating capability. Along with the endeavor to develop thermoelectric materials with greater figures of merit, the geometrical and structural optimization of thermoelectric generators is equally critical for maximum power output and efficiency. Green energy strategies that are constantly updated are a viable option for addressing the global energy issue while also protecting the environment. There have been significant focuses on the development of thermoelectric modules for a range of solar, automotive, military, and aerospace… More >

    Development of Magnetite/Graphene Oxide Hydrogels from Agricultural Wastes for Water Treatment

    Hebat-Allah S. Tohamy, Mohamed El-Sakhawy, Samir Kamel*

    Journal of Renewable Materials, Vol.10, No.7, pp. 1889-1909, 2022, DOI:10.32604/jrm.2022.019211

    Abstract A novel magnetic hydrogel loaded with graphene oxide (GO) was developed in this study. Firstly, GO was prepared from bagasse through a single step via oxidation in the presence of ferrocene under muffled atmospheric conditions, followed by the loading of different amounts of magnetite onto GO via co-precipitation reaction of iron onto GO sheets. Finally, the 2-acrylamido-2-methyl-1-propane sulfonic acid was grafted onto carboxymethyl cellulose in the presence of magnetite GO and N, N′-methylenebisacrylamide as crosslinker yielded hydrogel. The structure, morphological, and thermal behavior of the prepared hydrogels were investigated. In addition, the adsorption performance of More > Graphic Abstract

    Microenvironment promotes cytoskeleton remodeling and adaptive phenotypic transition

    MARIANO BIZZARRI*, PAOLA PONTECORVI

    BIOCELL, Vol.46, No.6, pp. 1357-1362, 2022, DOI:10.32604/biocell.2022.018471

    Abstract The cytoskeleton includes three main classes of networked filaments behaving as a coherent and complex structure that confers stability to cell shape while serving as sensor of internal/extracellular changes. Microenvironmental stimuli interfere with the non-linear dynamics that govern cytoskeleton architecture, namely by fostering symmetry breakings and transitions across different phenotypic states. Such process induces a wholecoherent adaptive response, involving the reprogramming of biochemical and gene-expression patterns. These characteristics are especially relevant during development, and in those conditions in which a deregulated crosstalk between cells and the stroma is at the core of the pathological process.

    Fluid and Osmotic Pressure Balance and Volume Stabilization in Cells

    Peter M. Pinsky*

    CMES-Computer Modeling in Engineering & Sciences, Vol.129, No.3, pp. 1329-1350, 2021, DOI:10.32604/cmes.2021.017740

    Abstract A fundamental problem for cells with their fragile membranes is the control of their volume. The primordial solution to this problem is the active transport of ions across the cell membrane to modulate the intracellular osmotic pressure. In this work, a theoretical model of the cellular pump-leak mechanism is proposed within the general framework of linear nonequilibrium thermodynamics. The model is expressed with phenomenological equations that describe passive and active ionic transport across cell membranes, supplemented by an equation for the membrane potential that accounts for the electrogenicity of the ionic pumps. For active ionic More >

    Ayesha Maqbool1,*, Farkhanda Afzal2, Tauseef Rana3, Alina Mirza4

    Intelligent Automation & Soft Computing, Vol.28, No.3, pp. 653-667, 2021, DOI:10.32604/iasc.2021.017506

    Abstract This paper presents a co-operative, self-organisation method for Multiple Autonomous Vehicles aiming to share surveillance responsibilities. Spatial organization or formation configuration of multiple vehicles/agents’ systems is crucial for a team of agents to achieve their mission objectives. In this paper we present simple yet efficient thermodynamic inspired formation control framework. The proposed method autonomously allocates region of surveillance to each vehicle and also re-adjusts the area of their responsibilities during the mission. It provides framework for heterogeneous UAVs to scatter themselves optimally in order to provide maximum coverage of a given area. The method is… More >

    YANJUAN LIAO1,#, DONGLING YU2,#, XIAOFANG QIN1, JINMEI WU1, HUI WEI1, HUI LI1, XIANGYING MA1,*, ZAIYIN HUANG1,*

    BIOCELL, Vol.44, No.4, pp. 703-711, 2020, DOI:10.32604/biocell.2020.012047

    Abstract Despite the great potential of photosynthetic microbes in the production of renewable fuels, value-adding chemicals, and water treatment, etc., commercial utilization of them is significantly hindered by the lack of techniques to accurately monitor the thermodynamic and kinetic characteristics of the In-situ growth of microbes under controlled light illumination for optimal cultivation. Herein, we demonstrated that a newly developed highly sensitive photo-microcalorimetric system successfully captured the impacts of the light wavelength and strength on the thermodynamic and kinetic parameters of the In-situ growth of Rhodopseudomonas palustris, a representative photosynthetic microorganism. To our best knowledge, this is the More >

    On the Design and Optimization of a Clean and Efficient Combustion Mode for Internal Combustion Engines through a Computer NSGA-II Algorithm

    Xiaobin Shu, Miaomiao Ren*

    FDMP-Fluid Dynamics & Materials Processing, Vol.16, No.5, pp. 1019-1029, 2020, DOI:10.32604/fdmp.2020.09564

    Abstract In order to address typical problems due to the huge demand of oil for consumption in traditional internal combustion engines, a new more efficient combustion mode is proposed and studied in the framework of Computational Fluid Dynamics (CFD). Moreover, a Non-dominated Sorting Genetic Algorithm (NSGA-II) is applied to optimize the related parameters, namely, the engine methanol ratio, the fuel injection time, the initial temperature, the Exhaust Gas Re-Circulation (EGR) rate, and the initial pressure. The so-called Conventional Diesel Combustion (CDC), Homogeneous Charge Compression Ignition (HCCI) and the Reactivity Controlled Compression Ignition (RCCI) combustion modes are… More >
