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.

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.

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.

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 to . Interestingly, human blood also demonstrates yield stress, although much lower, ranging from to . 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.

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.

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.

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.

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.

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.
