We noticed that in literature, the term Pickering emulsion (PE) is used as soon as ingredients contain particles, and in this review, we ask ourselves if that is done rightfully so. The basic behavior taking place in particle-stabilized emulsions leads to the conclusion that the desorption energy of particles is generally high making particles highly suited to physically stabilize emulsions. Exceptions are particles with extreme contact angles or systems with very low interfacial tension.

Particles used in food and biobased applications are soft, can deform when adsorbed, and most probably have molecules extending into both phases thus increasing desorption energy. Besides, surface-active components will be present either in the ingredients or generated by the emulsification process used, which will reduce the energy of desorption, either by reduced interfacial tension, or changes in the contact angle. In this paper, we describe the relative relevance of these aspects, and how to distinguish them in practice.

Practical food emulsions may derive part of their stability from the presence of particles, but most likely have mixed interfaces, and are thus not PEs. Especially when small particles are used to stabilize (sub)micrometer droplets, emulsions may become unstable upon receiving a heat treatment. Stability can be enhanced by connecting the particles or creating network that spans the product, albeit this goes beyond classical Pickering stabilization. Through the architecture of PEs, special functionalities can be created, such as reduction of lipid oxidation, and controlled release features.

我们注意到，在文献中，只要成分中含有微粒，就会使用皮克林乳液（PE）这一术语。从颗粒稳定乳液的基本行为可以得出结论：颗粒的解吸能通常很高，因此颗粒非常适合物理稳定乳液。食品和生物基应用中使用的颗粒很软，吸附时会变形，而且很可能有分子延伸到两相，从而增加了解吸能。此外，配料中或乳化过程中会产生表面活性成分，这些成分会通过降低界面张力或改变接触角来降低解吸能。在本文中，我们将介绍这些方面的相对相关性，以及如何在实践中区分它们。实用食品乳剂的部分稳定性可能来自颗粒的存在，但很可能具有混合界面，因此不是 PE。特别是当使用小颗粒来稳定（亚）微米液滴时，乳剂在接受热处理后可能会变得不稳定。尽管这已超出了传统的皮克林稳定法，但可通过连接颗粒或创建横跨产品的网络来增强稳定性。通过聚乙烯的结构，可以创造出特殊的功能，如减少脂质氧化和控制释放功能。

Magnetic nanoparticles (MNPs) have garnered significant attention from researchers due to their numerous technologically significant applications in diverse fields, including biomedicine, diagnostics, agriculture, optics, mechanics, electronics, sensing technology, catalysis, and environmental remediation. The superparamagnetic nature of MNP is exploited for many applications and remains fascinating to study many fundamental phenomena. The uniqueness of this review is that it gives an in-depth review of different synthesis approaches adopted for preparing magnetic nanoparticles and nanoparticle formation mechanisms, functionalizing them with different capping agents, and applying different functionalized magnetic nanoparticles. The important synthesis techniques covered include coprecipitation, microwave-assisted, sonochemical, sol-gel, microemulsion, hydrothermal/solvothermal, thermal decomposition, and mechano-chemical synthesis. Further, the advantages and disadvantages of each technique are discussed, and tables show important results of prepared particles. Other aspects covered in this review are the dispersion of magnetic nanoparticles in the continuous matrix, the influence of surface capping on high-temperature thermal stability, the long-term stability of ferrofluids, and applications of functionalized magnetic nanoparticles. For effective utilization of the ferrite nanoparticles, it is essential to formulate thermally and colloidally stable magnetic nanoparticles with desired magnetic properties. Capping enhances the phase transition temperature and long-term colloidal stability. Magnetic nanoparticles capped or functionalized with specific binding species, specific components like drugs, or other functional groups make them suitable for applications in biotechnology/biomedicine. Recent studies reveal the tremendous scope of MNPs in therapeutics and theranostics. The requirements for nanoparticle size, morphology, and physio-chemical properties, especially magnetic properties, functionalization, and stability, vary with applications. There are also challenges for precise size control and the cost-effective production of nanoparticles in large quantities. The review should be an ideal material for researchers working on magnetic nanomaterials and an excellent reference for freshers.

磁性纳米粒子（MNPs）在生物医学、诊断学、农业、光学、力学、电子学、传感技术、催化和环境修复等多个领域都有大量重要的技术应用，因此备受研究人员的关注。MNP 的超顺磁性在许多应用中都得到了开发，而且在研究许多基本现象方面仍然具有吸引力。本综述的独特之处在于，它深入评述了制备磁性纳米粒子所采用的不同合成方法和纳米粒子的形成机制，用不同的封端剂对其进行功能化，以及应用不同的功能化磁性纳米粒子。其中涉及的重要合成技术包括共沉淀、微波辅助、声化学、溶胶凝胶、微乳液、水热/溶热、热分解和机械化学合成。此外，还讨论了每种技术的优缺点，并用表格显示了制备颗粒的重要结果。本综述涉及的其他方面包括磁性纳米粒子在连续基体中的分散、表面封装对高温热稳定性的影响、铁流体的长期稳定性以及功能化磁性纳米粒子的应用。为了有效利用铁氧体纳米粒子，必须配制出具有所需磁性能的热稳定性和胶体稳定性磁性纳米粒子。封端可提高相变温度和长期胶体稳定性。用特定的结合物种、特定的成分（如药物）或其他功能基团对磁性纳米粒子进行封端或功能化，使其适合应用于生物技术/生物医药领域。最近的研究表明，磁性纳米粒子在治疗和治疗学方面有着巨大的应用空间。不同的应用对纳米粒子的尺寸、形态和物理化学特性（尤其是磁性、功能化和稳定性）的要求各不相同。此外，在精确控制尺寸和以具有成本效益的方式大量生产纳米粒子方面也存在挑战。这篇综述应该是从事磁性纳米材料研究人员的理想材料，也是新手的极佳参考资料。

Nanoparticles are vital to a broad range of applications including commercial formulations, sensing and advanced material synthesis. Nanoparticles can come in a variety of shapes including cubes, polyhedra, rods, and prisms, and recent literature has demonstrated the importance of nanoparticle shape to downstream function (such as cellular uptake). While researchers routinely characterise nanoparticle shape using electron microscopy techniques, this generally requires drying of the samples. Many particles (e.g. lipid nanoparticles or polymer particles) change with drying, so complementary solution based techniques are needed. Scattering techniques can be used to characterise such nanoparticles in suspension, overcoming many of the limitations of other techniques. Here we review the current state of the art in the characterisation of complex nanoparticles (non-spherical and multi-layered) using advanced scattering techniques including light, X-ray, and neutron scattering. Recent improvements in instrument availability and data analysis makes these techniques much more accessible to researchers. This review provides an introduction to these techniques aimed at all researchers working with nanoparticles, in the hope that full characterisation of nanoparticles in solution becomes standard practice.

纳米粒子对于商业配方、传感和先进材料合成等广泛应用至关重要。纳米粒子的形状多种多样，包括立方体、多面体、棒状和棱柱状，最近的文献表明了纳米粒子形状对下游功能（如细胞吸收）的重要性。虽然研究人员通常使用电子显微镜技术来表征纳米粒子的形状，但这通常需要对样品进行干燥处理。许多颗粒（如脂质纳米颗粒或聚合物颗粒）在干燥过程中会发生变化，因此需要基于溶液的补充技术。散射技术可用于表征悬浮液中的此类纳米颗粒，克服了其他技术的许多局限性。在此，我们回顾了利用光散射、X 射线散射和中子散射等先进散射技术表征复杂纳米粒子（非球形和多层）的技术现状。最近在仪器可用性和数据分析方面的改进使研究人员更容易获得这些技术。本综述向所有从事纳米粒子研究的人员介绍了这些技术，希望溶液中纳米粒子的全面表征成为标准实践。

A hydrolyzed protein is a blend of peptides and amino acids which is the result of hydrolysis by enzymes, acids or alkalis. The Bioactive Peptides (BPs) show important biological roles including antioxidant, antimicrobial, anti-diabetic, anti-cancer, and anti-hypertensive effects, as well as positive effects on the immune, nervous, and digestive systems. Despite the benefits of BPs, challenges such as undesired organoleptic properties, solubility profile, chemical instability, and low bioavailability limit their use in functional food formulations and dietary supplements. Nanocarriers have emerged as a promising solution for overcoming these challenges by improving the stability, solubility, resistance to gastric digestion, and bioavailability, allowing for the targeted and controlled delivery, and reduction or masking of the undesirable flavor of BPs. This study reviews the recent scientific accomplishments concerning the loading of BPs into various nanocarriers including lipid, carbohydrate and protein based-nanocarriers. A special emphasis is given to their application in food formulations in accordance to the challenges associated with their use.

Currently, various types of emulsions can be applied to a wide range of systems. Emulsions are thermodynamically unstable systems, and their crystallization can be affected by a variety of factors. The nucleation and growth processes of emulsion crystal networks are determined on the basis of reported theoretical and experimental methods. The issues addressed include changes in the apparent crystal morphology of samples, changes in thermal properties with respect to temperature, changes in boundary conditions, and changes in the various applications of emulsions as feedstocks or in processing and storage methods. Changes in a variety of common emulsions during constant-temperature storage and unavoidable temperature fluctuations (e.g., multiple freeze-thaw cycles) are considered. Different methods for controlling the crystalline stability of these colloidal systems are also discussed. This review outlines the crystallization mechanism of emulsions during their food processing and storage.

Boiling heat transfer has become increasingly importance in a variety of industrial fields, but it involves chaotic nature phenomena that remain experimentally challenging. From the perspective of nucleation, bubble embryos emerge at the early stage on extremely small time and length scales. Therefore, molecular dynamics (MD) simulation is a popular and useful tool to uncover the distinctive boiling mechanisms at microscale.

沸腾传热在各种工业领域的重要性日益凸显，但其中涉及的混沌性质现象在实验上仍具有挑战性。从成核的角度来看，气泡胚胎在早期出现的时间和长度尺度都非常小。因此，分子动力学（MD）模拟是在微观尺度上揭示独特沸腾机制的一种流行而有用的工具。近来，这种方法取得了有意义的成果，但复杂沸腾过程背后的现状和瓶颈仍然难以捉摸。本文全面回顾了截至 2024 年的 129 篇关于气泡成核和沸腾传热的最新研究成果。同时，简要介绍了 MD 的基本概念，包括 MD 原理、力场和成核相关参数的确定。与微观沸腾不同，气泡成核源于微/纳米尺度上势能和动能之间的竞争。然后，深入阐明了气泡成核的关键因素，如界面润湿性和混合物成分。此外，还系统地讨论了被动和主动技术，以揭示沸腾传热增强的内在机制。最后，确定了 MD 模拟所需的持续试验，并展望了如何应对这些挑战。本综述旨在对沸腾机理进行最新总结，并引起人们对先进 MD 技术发展的更多关注。

Superhydrophobic systems have fascinated the human kind since the earliest observations of the repellence of water droplets by biological systems. Currently, superhydrophobic materials (SHMs), often inspired by nature and engineered as thin coatings, become an important class of complex systems with numerous industrial implementations. The most important applications of SHMs cover waterproof, self-cleaning, anti−/deicing, anti-fogging, and catalytic systems/units, e.g., in textiles, civil and military engineering, automotive and space industry, and water-from-oil separating systems. In a few above areas, SHMs proved also to be tailorable as smart, i.e., reversibly stimuli-responsive and/or recyclable solutions. In all of those emerging fields, carbon – as the ‘sixth element’ – represents one of the most prospective components, also in the ‘only‑carbon’-based systems. The versatility of carbon (nano)materials, supported by their surface and morphology/topology tunability at from the nano- to macroscale, is vital in the manufacturing of high-performance SHMs. Here, we review only-sp²-hybridized nanocarbon SHMs, i.e., materials exhibiting water contact angle (WCA) >150°, from molecular design to synthesis and evaluation of their application-oriented properties, including WCA. The nanocarbons – pristine/as-made, (non-)covalently functionalized and in a form of carbon‑carbon composites – are analyzed according to their dimensionality: 0D fullerenes, 1D carbon nanotubes (CNTs), 2D graphene, and 3D carbon nanofibers (CNFs). Importantly, this review intends to provide premises toward novel sp²-nanocarbon SHMs, indicating nanowettability and Hansen Solubility Parameters the key ones.

自最早观察到生物系统排斥水滴以来，超疏水性系统就一直吸引着人类。目前，超疏水性材料（SHMs）通常受到自然界的启发，被设计成薄涂层，成为一类重要的复杂系统，在工业领域得到广泛应用。超疏水材料最重要的应用领域包括防水、自清洁、防/除冰、防雾和催化系统/单元，如纺织品、民用和军事工程、汽车和航天工业以及油水分离系统。事实证明，在上述几个领域，SHMs 还可以作为智能解决方案，即可逆刺激响应和/或可回收解决方案。在所有这些新兴领域中，碳--作为 "第六元素"--是最有前景的成分之一，在 "纯碳 "系统中也是如此。从纳米到宏观尺度，碳（纳米）材料的表面和形态/拓扑可调性支持了其多功能性，这对于制造高性能 SHM 至关重要。在此，我们综述了仅sp2-杂化的纳米碳 SHMs，即表现出水接触角（WCA）>150°的材料，从分子设计到合成，以及对其应用导向特性（包括 WCA）的评估。本综述根据纳米碳的维度（0D 富勒烯、1D 碳纳米管 (CNTs)、2D 石墨烯和 3D 碳纳米纤维 (CNFs)）对其进行了分析，这些纳米碳包括棱柱形碳/人造碳、（非）共价官能化碳以及碳碳复合材料。重要的是，本综述旨在为新型 sp2 纳米碳 SHM 提供前提条件，并指出纳米润湿性和汉森溶解度参数是关键因素。
