流体相平衡发表了有关流体、固体和界面平衡和传输特性的实验、理论和应用研究的高质量论文。感兴趣的主题包括物理/相和化学平衡、平衡和非平衡热物理性质、基本热力学关系和稳定性。该期刊的核心系统包括纯物质和有机和无机材料的混合物，包括聚合物、生物化学物质和表面活性剂，它们对组成和纯度有充分的表征，以使结果得以重现。只有当热力学研究被包括在内时，合金才有意义，纯材料研究将不被考虑。在所有情况下，作者应提供结果的物理或化学解释。实验研究可以包括在所有温度、压力和成分条件下的测量，包括临界和超临界。测量应与系统和基本或应用感兴趣的条件相关联，并且可能不仅是常规数据的集合，例如物理性质或在接近环境的有限压力和温度下的溶解度测量，或者表面活性剂研究严格关注胶束化或胶束结构。报告共同数据的论文必须附有新的物理见解和/或当代或新的理论或技术。所有数据报告和分析将由NIST检查是否符合http://trc.nist.gov/fpe-support.html上发布的要求。理论和计算研究可以包括状态方程、关联或预测模型、分子动力学和蒙特卡罗模拟、统计热力学、量子化学以及其他应用数学和计算方法。报告新理论和模型的研究预计将显示预测能力和准确性与适用数据和当代现有模型的充分比较。只有在提供了方法的全部细节，并将精度与现有的物理模型进行了比较，或没有可用的热力学模型时，才会考虑对人工神经网络、机器学习和类似方法的贡献。所有报告的计算研究必须能被其他人完全复制。因此，所有算法和方法都应详细描述，模型、力场和电子结构方法的所有参数应在手稿或支持信息中明确给出。该杂志发表了完整的研究论文和简短的交流，以描述快速出版是必不可少的新思想。鼓励进行评论，并应与总编辑协商准备。期刊不会发表在其他期刊上部分或全部出现的、剽窃其他作品或引用不完整的文章；将使用http://www.itheticate.com/products/crosscheck上的软件进行验证。文本必须是英文的，并应清晰，结构良好的风格，没有语法和拼写错误。

Fluid Phase Equilibria publishes high-quality papers dealing with experimental, theoretical, and applied research related to equilibrium and transport properties of fluids, solids, and interfaces. Subjects of interest include physical/phase and chemical equilibria; equilibrium and nonequilibrium thermophysical properties; fundamental thermodynamic relations; and stability. The systems central to the journal include pure substances and mixtures of organic and inorganic materials, including polymers, biochemicals, and surfactants with sufficient characterization of composition and purity for the results to be reproduced. Alloys are of interest only when thermodynamic studies are included, purely material studies will not be considered. In all cases, authors are expected to provide physical or chemical interpretations of the results.Experimental research can include measurements under all conditions of temperature, pressure, and composition, including critical and supercritical. Measurements are to be associated with systems and conditions of fundamental or applied interest, and may not be only a collection of routine data, such as physical property or solubility measurements at limited pressures and temperatures close to ambient, or surfactant studies focussed strictly on micellisation or micelle structure. Papers reporting common data must be accompanied by new physical insights and/or contemporary or new theory or techniques. All data reports and analyses will be examined by NIST for consistency with the requirements posted at http://trc.nist.gov/FPE-Support.htmlTheoretical and computational studies can include equations of state; correlations or predictive models; molecular dynamics and Monte Carlo simulations; statistical thermodynamics; quantum chemistry; and other applied mathematical and computational approaches. Research reporting new theories and models are expected to show adequate comparisons of predictive ability and accuracy with both applicable data and contemporary existing models. Contributions on artificial neural networks, machine learning, and similar approaches will only be considered when full details of the methodology are provided and comparisons of accuracy are made with existing physically-based models, or if no thermodynamic models are available. All reported computational studies must be fully reproducible by others. As such all algorithms and methods should be described in sufficient detail, all parameters for models, force fields, and electronic structure methods should be given explicitly in the manuscript or supporting information.The journal publishes full research papers and also short communications to describe emerging ideas for which rapid publication is essential. Critical reviews are encouraged and should be prepared in consultation with the Editor-in-Chief. The journal will not publish articles that have appeared partially, or completely, in other journals, that plagiarize other works, or that are incompletely referenced; verification will be made using the software at http://www.ithenticate.com/products/crosscheck. The text must be in English and should be clear, in a well-structured style, and be free of grammatical and spelling errors.
