We review experimental evidence and theoretical/modeling approaches on Wormlike Micelles (WLMs) dynamics in linear and nonlinear regimes. We focus on recent works regarding the extraction of quantitative microscopic information from linear rheology data and the possibility of quantifying the fast relaxation processes. Models for WLMs undergoing reptation and chain sequence rearrangement are discussed. Strong shear and elongational flows that can cause interesting phenomena, e.g. chain scission, structure formation, and elastic instabilities in WLMs, are considered. More specifically, start-up shear flow in the nonlinear regime, LAOS experiments, and relative data treatment are discussed, together with shear-banding phenomena and their dynamics, inertio-elastic instabilities, and secondary flow. Different techniques for measuring WLMs in extensional flow are compared, referring in particular to the recent dripping-onto-substrate (DoS) extensional rheometry, which is able to address some shortcomings of the CaBER technique. We finally deal with the potential source of triggering flow profiles and secondary flows with fluid properties and external conditions.

Extrusion 3D printing has achieved significant progress, emerging as one of the most important 3D printing methods for designing biologically relevant organs or tissue substitutes by bioprinting cell-laden inks. Swollen polymeric networks, or hydrogels, have emerged as the preferred biomaterial for fabricating cell-encapsulated inks appropriate for layer-by-layer extrusion through nozzles. The design aspects of the hydrogels play a crucial role in determining the flow behavior of these inks. The review first overviews the fundamentals of rheological measurements in extrusion-based 3D printing, followed by hydrogel ink design approaches, and their implications on the rheological properties. We also discuss the effect of cell density on rheology and 3D bioprinting outcomes. We identify the existing challenges in the field of extrusion bioprinting and discuss future directions to address them.

Light sheet fluorescence microscopy (LSFM), uses a thin sheet laser illumination to rapidly image samples with greatly reduced photodamage versus previous techniques. The flexibility of the technique has powered significant advances in biology research by connecting length scales from individual cells to entire developmental embryos. For similar reasons, LSFM is poised to enhance mesoscale imaging of complex fluid microstructures in fundamental and commercial systems. This work introduces the LSFM technique and reviews some of its complex fluid applications along with examples of its use in food, biomaterial, and emulsion product samples. The technique is shown to nicely complement existing complex fluid characterization methods because of its breadth of length scale resolution and its lack of photobleaching effects. New product applications for LSFM are identified and discussed, suggesting additional integration with existing techniques.

Integrated photo-rechargeable battery systems represent a significant advancement in sustainable energy storage and conversion by combining photovoltaic energy harvesting with direct energy storage in a compact design. Although initially studied in the 1970s, interest in this field has surged in recent years. Due to the multidisciplinary nature of this topic, researchers from diverse backgrounds approach it with varying methodologies, resulting in highly diverse cell designs and inconsistent performance metrics. These variations complicate the comparison and evaluation of system efficiency and functionality. This review presents a comprehensive overview of the field's development and current state, from early photoelectrochemical approaches to modern integrated designs. Additionally, it addresses the challenge of performance evaluation by compiling current approaches to performance measurement and proposing standardized evaluation parameters under defined conditions. This dual focus on field overview and metrics standardization aims to provide both a thorough understanding of solar electrochemical energy storage technologies and a framework for their consistent evaluation, which is critical for advancing these technologies.

Foams in cosmetics: New trends in detergency, friction, coatings 化妆品中的泡沫:去污力、摩擦力和涂层方面的新趋势

Foams and bubbles are particularly valuable in cosmetics as they can provide functional, sensorial, and emotional benefits. They are ubiquitous in cleaning products for skin and hair containing complex mixtures of short chain surfactants, polymers and other technical (salts, glycols…) or beneficial ingredients (silicones, oils, actives…). Other cosmetic applications (styling, skincare, coloration, etc.) may use foam format for their light feel and easy spreading on hair and skin, covering a wide range of compositions from alcoholic solutions to oily gels.
Besides aspects related to the formation, stability, and structure of foams (that are key in continuously optimizing the performance and usage of foam-based cosmetic products), the right choices of natural and bio-based ingredients will also help to overcome actual challenges such as sustainability. Moreover, their contact and spreading properties on natural surfaces are essential for various applications properties such as cleansing and deposition of topical cosmetic and dermatological products, etc.
In this opinion article, we describe the recent advances and challenges in using foams in cosmetics from both physical and formulation perspectives. We focus our attention on the foam–substrate interaction and recent studies opening new concepts and solutions of interest for cosmetic applications such as foam tribology and deposition.

This review explores the potential of Quantum Dot Solar Cells (QDSCs) in revolutionizing photovoltaic technology. By leveraging the unique properties of quantum dots, QDSCs promise enhanced efficiency and lower production costs. Key innovations like tandem quantum dot solar cells (TQDSCs) and hybrid organic-quantum dot (HQD) solar cells are highlighted for their ability to absorb a broader light spectrum and combine organic semiconductors with quantum dots.
However, challenges such as long-term stability, material toxicity, and scalability remain obstacles to commercial viability. The review calls for continued research into non-toxic materials, better encapsulation techniques, and cost-effective manufacturing processes. A forward-looking perspective emphasizes that interdisciplinary efforts are crucial for integrating QDSCs into the renewable energy landscape, potentially driving a more sustainable future.

Luca Campagiorni, Monica Tonelli, Francesca Ridi
This review offers an introductory examination of the challenges involved in formulating limestone-based ternary blended cements intended for both specialists and nonexperts in cement chemistry. The environmental impact of cement production and the raising awareness on climate changes has led to a progressive shift toward sustainable practices, emphasizing the critical need for eco-friendly construction materials. Here, the motivation for adopting ternary blends is explored, with a particular focus on supplementary cementitious materials (SCMs) otherwise classified as wastes, such as ground granulated blast-furnace slag, silica fume, fly ash, and metakaolin, which contribute to sustainability improvements. To facilitate understanding, a glossary of technical terms is provided alongside an overview of the cement hydration process and the distinct characteristics of various SCMs.
The review focuses on the performance of binary and ternary cement blends, giving particular consideration to the synergistic effects observed when limestone is combined with SCMs in ternary formulations. Key properties of specific ternary blends are highlighted, unraveling their potential to enhance both performance and environmental sustainability. Finally, the review provides a perspective for future developments, reflecting on the broader implications of these materials for promoting sustainable construction practices within the industry.

The diversity of both natural and non-natural amino acids provides a strong foundation for the synthesis of a wide array of surfactants and offers the possibility to control the interactions at interfaces and within self-assembly processes.
This review provides an overview of the latest developments of amino acid-based surfactant over the past decade, with a particular focus on the past five years. A detailed overview of the synthesis is first given, and physicochemical properties of surfactants derived from both standard amino acids, and non-natural amino acids are discussed. From enhancing foaming to controlling rheological properties, these surfactants meet a wide range of application-specific requirements. This is illustrated in various fields, such as drug delivery or mineral ore flotation.
Although single amino acid derivatives have been deeply explored, surfactants based on multiple amino acids are also discussed for the new possibilities in self-assembly and potential various applications they offer.
