Scaffolds used in regenerative medicine are increasingly expected to address personalization, bioactivity, and sustainability, underscoring the need for characterization methods that reliably predict safety and efficacy. Isothermal microcalorimetry (IMC) offers a highly sensitive, label-free, real-time measurement of heat flow from energy-generating or -consuming process at scaffold interfaces. By monitoring microbial activity, host cell metabolism, material stability, and responses to environmental or therapeutic factors, IMC provides physiologically relevant insight into scaffold performance over extended periods. Its non-destructive, low-preparation, and passive nature preserves samples for complementary analyses, making it a versatile yet underutilized tool in biomedical research. This review introduces IMC for scaffold design and characterization, emphasizing its capacity to evaluate vulnerability to biofilm formation and the effectiveness of anti-biofilm strategies. It further explores applications in tracking scaffold formation, assessing host cell-material interactions and tissue development, and probing the antitumor potential of engineered scaffolds. The review concludes with a perspective on IMC's role in advancing scaffold translation within the evolving regulatory landscape shaped by the FDA Modernization Acts 2.0 and 3.0.
人们越来越期望再生医学中使用的支架能够解决个性化、生物活性和可持续性问题,这强调了对可靠预测安全性和有效性的表征方法的需求。等温微热法(IMC)提供了一种高灵敏度、无标签、实时测量支架界面上能量产生或消耗过程的热流的方法。通过监测微生物活性、宿主细胞代谢、材料稳定性以及对环境或治疗因素的反应,IMC为长时间的支架性能提供了生理学相关的见解。它的非破坏性,低制备和被动的性质保留了样品的补充分析,使其成为生物医学研究中多功能但未充分利用的工具。本文介绍了IMC用于支架的设计和表征,强调了其评估生物膜形成脆弱性的能力和抗生物膜策略的有效性。它进一步探索了在跟踪支架形成,评估宿主细胞-物质相互作用和组织发育以及探测工程支架抗肿瘤潜力方面的应用。本综述总结了IMC在FDA现代化法案2.0和3.0形成的不断发展的监管环境中推进支架翻译的作用。

The liquid-liquid phase transformation during the solidification of an immiscible alloy provides a route for developing the in-situ particulate composite of high performances. Researches demonstrate that the repulsion of solidification interface to the minority phase droplet may cause the formation of a microstructure with the minority phase droplets/particles enriched on grain boundaries or even a macro-segregated microstructure. The interaction between a solidification interface and droplets has not been well considered up to now. Generally, the models for the interaction between a particle and solidification interface were used to predicate the interaction between a droplet and solidification interface. In fact, the droplet nearby solidification interface may behave much differently from a particle due to its fluidity. This work develops a model describing the interaction between an advancing solidification interface and its nearby droplets. The model is verified by comparing with the experimental results. The factors influencing the capture of droplets by solidification interface are discussed in details. The numerical results demonstrate that the Marangoni migration of droplets makes the capture of droplets harder compared with the capture of particles. With the increase of the relative viscosity of the droplet to the matrix melt, the capture the droplet becomes easy. The Marangoni migration velocity is negligible small for a droplet of very high viscosity. The capture of such a droplet by solidification interface is similar to the capture of a solid particle.
非混相合金凝固过程中的液液相转变为原位颗粒复合材料的高性能发展提供了一条途径。研究表明,凝固界面对少数相液滴的排斥作用可能导致少数相液滴/颗粒在晶界富集,甚至形成宏观偏析的微观组织。凝固界面与液滴之间的相互作用目前还没有得到很好的研究。一般采用颗粒与凝固界面相互作用模型来预测液滴与凝固界面的相互作用。事实上,凝固界面附近的液滴由于其流动性,其行为可能与颗粒大不相同。这项工作建立了一个模型,描述了一个前进的凝固界面和它附近的液滴之间的相互作用。通过与实验结果的对比,验证了模型的正确性。详细讨论了影响凝固界面捕获液滴的因素。数值结果表明,液滴的Marangoni迁移使得液滴的捕获比颗粒的捕获更加困难。随着液滴对基体熔体相对粘度的增加,液滴的捕获变得容易。对于粘度非常高的液滴,马兰戈尼迁移速度可以忽略不计。凝固界面对这种液滴的捕获类似于对固体颗粒的捕获。

The rising global need for natural gas and the reduction of greenhouse gas emissions highlight the significance of innovative storage solutions like hydrate-based solidified gas technology. Gas hydrates offer great potential as an efficient and safe method for storing methane and carbon dioxide. However, it faces operational challenges, primarily due to foam formation during gas recovery, which adversely affects efficiency and increases operational costs. As the gas hydrates dissociate, they release significant volumes of gas into the surrounding water. Surfactants reduce the surface tension of this water, enabling the released gas to form stable bubbles encased in thin liquid films. This review highlights innovative approaches to developing foam-free promoters, specifically focusing on amino acids, biosurfactants, and nanoparticles that enhance hydrate formation while mitigating foaming issues. This review evaluates the mechanisms underlying these promoters' effectiveness, emphasizing their promotion power and foaming ability. Comparative analyses reveal that amino acids and biosurfactants enable rapid hydrate formation and effective gas storage under varied conditions, while nanoparticle systems provide structural stability and efficiency in complex environments. The performance of foam-free promoters is assessed under various conditions, including temperature, pressure, and salinity, revealing the importance of molecular mechanisms in promoting hydrate stability and efficiency. The potential of environmentally friendly materials, such as amino acids and biosurfactants, is emphasized, showcasing their effectiveness in reducing foam formation without compromising hydrate formation rates. Furthermore, their compatibility with renewable energy strategies aligns with global sustainability goals, making them pivotal for the commercial use of gas storage based on hydrates. The integration of advanced computational tools and systematic experimentation is advocated for optimizing promoter formulations, ultimately paving the way for the commercial viability of hydrate technologies. This synthesis of findings provides a comprehensive framework for future research and applications in the field of gas storage and recovery, underscoring the transformative potential of foam-free hydrate promoters in sustainable energy systems.
全球对天然气需求的不断增长和温室气体排放的减少凸显了创新存储解决方案的重要性,如基于水合物的固化气体技术。天然气水合物作为一种高效、安全的储存甲烷和二氧化碳的方法提供了巨大的潜力。然而,该方法也面临着运营方面的挑战,主要是由于在采气过程中形成泡沫,这对效率产生了不利影响,并增加了运营成本。当气体水合物解离时,它们会向周围的水中释放大量气体。表面活性剂降低了水的表面张力,使释放的气体形成包裹在薄液体薄膜中的稳定气泡。这篇综述强调了开发无泡沫促进剂的创新方法,特别是氨基酸、生物表面活性剂和纳米颗粒,它们可以促进水合物的形成,同时减轻泡沫问题。本文综述了这些促进剂的作用机制,重点介绍了它们的促进力和起泡能力。对比分析表明,氨基酸和生物表面活性剂能够在各种条件下快速形成水合物并有效储存气体,而纳米颗粒系统在复杂环境下提供结构稳定性和效率。对无泡沫促进剂在温度、压力和盐度等条件下的性能进行了评价,揭示了分子机制在促进水合物稳定性和效率方面的重要性。环境友好材料的潜力,如氨基酸和生物表面活性剂,被强调,展示了他们在不影响水合物形成速率的情况下减少泡沫形成的有效性。此外,它们与可再生能源战略的兼容性符合全球可持续发展目标,这对于基于水合物的天然气储存的商业应用至关重要。将先进的计算工具和系统的实验相结合,以优化促进剂配方,最终为水合物技术的商业可行性铺平道路。这一综合研究结果为未来在天然气储存和回收领域的研究和应用提供了一个全面的框架,强调了无泡沫水合物促进剂在可持续能源系统中的变革潜力。

Yield stress, a threshold shear stress indicating a fluid-like flow above and solid-like behaviour below, is inherent to several complex materials. Everyday fluids like toothpaste, ketchup, and body creams exhibit a yield stress on the order of 10 to 100Pa. Interestingly, human blood also demonstrates yield stress, although much lower, ranging from O103to O101Pa. The origin of the yield stress is attributed to a network of interacting red blood cells (RBCs), which arises from an attractive force between the RBCs, resisting flow under stress. Using scaling analysis, we predict yield stress based on the attractive force between RBCs. Moreover, we outline several techniques developed over the past few decades for accurate, rapid, and cost-effective measurement of the yield stress of blood. The advent of several techniques arises from the observation that healthy human blood generally possesses a lower yield stress compared to blood affected by various health conditions. This includes conditions such as cardiovascular or cerebrovascular diseases, hypertension, sickle cell disease, systemic sclerosis, as well as patients administered with anaesthesia or aspirin tablets, or those undergoing surgeries resulting in increased inflammation in the body. These diseases and phenomena occur because these health conditions alter the composition of blood, including changes in the volume fraction of RBCs, concentration of plasma proteins, as well as factors affecting the shape and deformability of the RBCs. We examine the difference between yield stress in healthy and diseased blood and argue that while blood yield stress may not significantly impact the physiology of blood flow, it can be valuable in clinical research for disease detection based on specific cut-off values. Additionally, we address challenges associated with applying yield stress in clinical research, such as huge variations in the measured yield stress across different techniques, or lack of large sample sizes.
屈服应力是一种阈值剪切应力,表明上面是类似流体的流动,下面是类似固体的行为,是几种复杂材料所固有的。牙膏、番茄酱和身体乳等日常液体的屈服应力约为10至100Pa。有趣的是,人类血液也显示出屈服压力,尽管要低得多,范围从o10 -3到O10-1Pa。屈服应力的起源归因于相互作用的红细胞(红细胞)网络,这是由红细胞之间的吸引力引起的,在压力下抵抗流动。利用标度分析,我们基于红细胞之间的吸引力来预测屈服应力。此外,我们概述了过去几十年来开发的几种技术,用于准确,快速和经济有效地测量血液的屈服应力。由于观察到健康的人类血液与受各种健康状况影响的血液相比,通常具有较低的屈服应力,因此出现了几种技术。这包括心脑血管疾病、高血压、镰状细胞病、系统性硬化症等疾病,以及接受麻醉或阿司匹林片剂治疗的患者,或接受手术导致体内炎症加剧的患者。这些疾病和现象的发生是因为这些健康状况改变了血液的组成,包括红细胞体积分数、血浆蛋白浓度的变化,以及影响红细胞形状和可变形性的因素。我们研究了健康血液和患病血液中屈服压力之间的差异,并认为虽然血液屈服压力可能不会显著影响血液流动的生理学,但它在基于特定临界值的疾病检测的临床研究中是有价值的。此外,我们还解决了在临床研究中应用屈服应力的相关挑战,例如不同技术测量的屈服应力存在巨大差异,或者缺乏大样本量。

Utilizing solar energy to drive chemical reactions for producing and storing energy via solar fuel is the ultimate way to build a sustainable future that addresses global fossil fuel requirements. In this context, designing efficient and cost-effective catalysts for H2 production and storage via water splitting and electrochemical energy storage is crucial for achieving advanced catalytic performance. Among numerous materials, layered double hydroxides (LDHs) have emerged as adaptable and efficient catalysts/co-catalysts/electrode materials in photocatalytic (PC), photoelectrochemical (PEC), electrocatalytic (EC) water splitting, and supercapacitor (SC) applications owing to their tunable transition metal cations, interlayer anions, defect formations, and robust physicochemical stability. A coupled structure of LDH‑carbonaceous materials (GO, g-C3N4, CNTs, and CQDs) exhibits unusual properties, including an enhanced surface area, hydrophilicity, and conductivity, which contribute to superior performance. This review focuses on recent advancements in the fabrication process of LDH‑carbonaceous hybrid towards EC, PC, PEC, and SC applications. Firstly, the characteristic features of LDH and the LDH‑carbonaceous hybrid were summarized. Then, the progress of the modification strategy elaborates on how the active carbonaceous species with LDHs alter the LDH‑carbonaceous hybrid towards enhancing overall water-splitting and storage performance for real-time applications. Further, this review summarizes the recent advancement in LDH properties through carbonaceous modification and deliberates the prospects for future advancement of energy applications.
利用太阳能驱动化学反应,通过太阳能燃料生产和储存能量,是建立可持续未来、解决全球化石燃料需求的最终途径。在这种情况下,设计高效、经济的催化剂,通过水分解和电化学储能来生产和储存氢气,对于实现先进的催化性能至关重要。在众多材料中,层状双氢氧化物(LDHs)由于其可调节的过渡金属阳离子、层间阴离子、缺陷形成和强大的物理化学稳定性,已成为光催化(PC)、光电化学(PEC)、电催化(EC)水分解和超级电容器(SC)应用中适应性强、高效的催化剂/助催化剂/电极材料。LDH -碳质材料(GO、g-C3N4、CNTs和CQDs)的耦合结构表现出不同寻常的性能,包括增强的表面积、亲水性和导电性,这些都有助于提高性能。本文综述了LDH -碳杂化材料在EC、PC、PEC和SC方面的最新研究进展。首先,综述了LDH和LDH -碳质杂化物的特性特征。然后,改性策略的进展详细说明了具有LDH的活性碳物质如何改变LDH -碳杂化物,从而提高实时应用的整体水分解和储存性能。综述了近年来碳质改性LDH的研究进展,并对其在能源领域的应用前景进行了展望。

Cyclodextrins and their derivatives (CDs) have become ideal host for constructing various self-assemblies due to their unique external hydrophilic and internal hydrophobic cavities. The primary supramolecular inclusion complexes (ICs) fabricated by CDs and amphiphilic molecules are able to further self-assemble into different high-order supramolecular self-assemblies with more complex structure and more diverse functions under various non-covalent interactions. Hence, in-depth understanding of the assembly mechanisms & modulating factors of amphiphilic molecules-CDs ICs and supramolecular self-assemblies (aggregates) as well as multiscale characterization methodologies is crucial for the design, construction, and application of novel CDs-based functional materials. Therefore, this paper systematically reviewed the latest research progress in supramolecular aggregates of CDs and amphiphilic molecules, and the influences of host, guest, and auxiliaries on the host-guest interaction and supramolecular aggregation were mainly discussed. Moreover, the relevant characterization methods of CDs-based supramolecular aggregates and their potential application prospect in different fields were also reviewed. Finally, the limitations and possible countermeasures of the current research on CDs-based supramolecular aggregates were briefly sorted out, in order to provide guidance for scientific research and practical applications in the field of CDs-based supramolecular self-assemblies.
环糊精及其衍生物由于其独特的外亲水性和内疏水性空腔而成为构建各种自组装体的理想宿主。由CDs和两亲性分子制备的初级超分子包合物(ICs)在各种非共价相互作用下能够进一步自组装成不同的高阶超分子自组装体,其结构更复杂,功能更多样。因此,深入了解两亲分子- cds集成电路和超分子自组装(聚集体)的组装机制和调节因素以及多尺度表征方法对于新型基于cds的功能材料的设计、构建和应用至关重要。因此,本文系统综述了CDs和两亲分子超分子聚集的最新研究进展,重点讨论了宿主、客体和助剂对主客体相互作用和超分子聚集的影响。综述了基于cds的超分子聚集体的相关表征方法及其在不同领域的潜在应用前景。最后,简要梳理了目前基于cds的超分子聚集体研究的局限性和可能的对策,以期为基于cds的超分子自组装领域的科学研究和实际应用提供指导。

Supramolecular cyclodextrin-based metal-organic frameworks (CD-MOFs) have several potential applications in the food industry, including as packaging materials, sensor components, adsorbents, and food additives. These porous, biocompatible materials combine the host-guest chemistry of cyclodextrins with the tunable structure of MOFs, enabling their properties to be tailored for specific applications within the food industry. In active and smart food packaging, CD-MOFs facilitate controlled release of encapsulated antimicrobial agents and antioxidants, thereby enhancing food quality, safety, and shelf life. Encapsulation of bioactive compounds, such as colors, flavors, nutraceuticals, and preservatives, in CD-MOFs can protect them from chemical degradation, microbial contamination, and volatilization. In food formulation, these supramolecular complexes enable the targeted delivery of functional additives, thereby improving sensory attributes and nutritional profiles. The biodegradable nature of many CD-MOFs aligns with the demand for eco-friendly materials, thereby reducing reliance on synthetic additives. Furthermore, CD-MOFs can be integrated into smart sensors to detect spoilage or contamination, ensuring real-time quality monitoring. Previous research suggests that CD-MOFs may provide innovative solutions to enhance food preservation, nutrition, and sustainability. However, challenges such as scalability, cost, and regulatory hurdles must be addressed to unlock their full potential. Continued research and development, coupled with interdisciplinary collaboration, will be crucial in overcoming these limitations and integrating CD-MOFs into food applications.
基于环糊精的超分子金属有机骨架(CD-MOFs)在食品工业中有几种潜在的应用,包括包装材料、传感器组件、吸附剂和食品添加剂。这些多孔的生物相容性材料将环糊精的主客体化学与mof的可调结构相结合,使其性能能够适应食品工业中的特定应用。在活性和智能食品包装中,cd - mof有助于控制封装的抗菌剂和抗氧化剂的释放,从而提高食品质量、安全性和保质期。在cd - mof中包封生物活性化合物,如颜色、香料、营养药品和防腐剂,可以保护它们免受化学降解、微生物污染和挥发。在食品配方中,这些超分子复合物能够靶向递送功能性添加剂,从而改善感官属性和营养状况。许多cd - mof的可生物降解特性符合对环保材料的需求,从而减少了对合成添加剂的依赖。此外,cd - mof可以集成到智能传感器中,以检测变质或污染,确保实时质量监控。先前的研究表明,cd - mof可能为提高食品的保存、营养和可持续性提供创新的解决方案。然而,必须解决诸如可扩展性、成本和监管障碍等挑战,以释放其全部潜力。持续的研究和开发,加上跨学科合作,对于克服这些限制和将cd - mof整合到食品应用中至关重要。

Marine organisms such as mussels, barnacles, and sandcastle worms demonstrate robust adhesion in aquatic environments. However, the mechanisms underlying their adhesive capabilities remain incompletely understood, and artificial adhesives with comparable performance have yet to be developed. Notably, most of these organisms achieve strong attachment to various underwater substrates through specialized protein-based structures. As a result, researchers have focused on developing peptide- and protein-based underwater adhesives inspired by these natural organisms in recent decades. This review first summarizes the natural protein-mediated underwater adhesive systems of representative marine organisms. It then provides a comprehensive overview of bio-inspired peptide- and protein-based underwater adhesives. Furthermore, the applications of these adhesives across various fields are discussed. Finally, the challenges and opportunities in the development of underwater adhesive biomaterials are briefly explored.
贻贝、藤壶和沙堡蠕虫等海洋生物在水生环境中表现出强大的附着力。然而,其粘合能力的机制仍然不完全清楚,具有类似性能的人工粘合剂尚未开发。值得注意的是,大多数这些生物通过专门的基于蛋白质的结构实现对各种水下底物的强烈附着。因此,近几十年来,受这些自然生物的启发,研究人员一直致力于开发基于肽和蛋白质的水下粘合剂。本文首先综述了具有代表性的天然蛋白质介导的海洋生物水下黏附系统。然后,它提供了生物启发肽和蛋白质为基础的水下粘合剂的全面概述。此外,还讨论了这些胶粘剂在各个领域的应用。最后,简要探讨了水下黏附生物材料发展面临的挑战和机遇。

Transformer fluids face major limitations in the dielectric strength and thermal conductivity of fluids, which hinders effective application in high-voltage applications. Adding nanoparticles holds potential for enhancement, but it is challenging to accomplish and maintain a stable dispersion because of a tendency toward agglomeration. Surfactants are found to act as critical stabilizing agents that aid in the dispersion of nanoparticles and temporal stability through steric and electrostatic interactions at the oil-nanoparticle interface. This review closely evaluates the preparation methodologies of dielectric nanofluids, paying specific attention to the functionality of surfactants and temporal stability effects. Surfactant-treated nanofluids showed temporal stability from a few weeks to a few months along with significant enhancements: breakdown voltage (up to 93.17%), dielectric constant (up to 47.4%), decrease in dissipation factor (up to 97.3%), increase in resistivity (up to 917.93%), and enhancement in thermal conductivity (up to 216.2%). These enhancements are necessarily connected to interfacial alterations that control charge trapping, polarization, and phonon conduction. Gaps between theoretical models of dielectric constant (like Maxwell-Garnett and Loyang models and others) and experimental findings are resolved to recommend enhancement considering surfactant-induced interfacial effects. Also, sustainability aspects such as biodegradability, toxicity, recyclability, and regulatory compliance are discussed. This review's uniqueness lies in a detailed discussion of interfacial mechanisms, model enhancements, and eco-friendly surfactant design, and suggestions for entering into molecular dynamics and interfacial modelling to rationally design environmentally sustainable, high-performance dielectric nanofluids.
变压器流体的介电强度和导热性受到很大限制,阻碍了变压器在高压环境中的有效应用。添加纳米颗粒具有增强的潜力,但由于倾向于团聚,实现和保持稳定的分散是具有挑战性的。表面活性剂被认为是一种关键的稳定剂,通过油-纳米颗粒界面上的空间和静电相互作用,有助于纳米颗粒的分散和时间稳定性。本文综述了电介质纳米流体的制备方法,特别关注表面活性剂的功能和时间稳定性效应。表面活性剂处理的纳米流体表现出从几周到几个月的时间稳定性,并显著增强:击穿电压(高达93.17%),介电常数(高达47.4%),耗散系数降低(高达97.3%),电阻率增加(高达917.93%),导热系数增强(高达216.2%)。这些增强必然与控制电荷捕获、极化和声子传导的界面改变有关。介电常数的理论模型(如Maxwell-Garnett和Loyang模型等)与实验结果之间的差距被解决,以推荐考虑表面活性剂诱导的界面效应的增强。此外,可持续性方面,如生物降解性,毒性,可回收性和法规遵从性进行了讨论。本文的独特之处在于详细讨论了界面机制,模型增强和环保表面活性剂设计,并建议进入分子动力学和界面建模,以合理设计环境可持续的高性能介电纳米流体。
