Summary: In this study, the formation and evolution of phosphatidylcholine-based liposomes were investigated in real-time using graphene liquid cell-transmission electron microscopy (GLC-TEM). The growth, fusion, and denaturation steps of liposomes were revealed. The study showed that complex lipid aggregates resembling micelles formed initially, which randomly merged and captured water to form small proto-liposomes. The liposomes grew in size until their membrane became convex and free of redundant phospholipids. Liposomes were found to fuse through lipid bilayers docking and the formation of a fusion pore. Denaturation of liposomes involved structural destabilization and membrane deformation followed by the leakage of encapsulated liquid.

Summary: The development of an accurate and sensitive sensor for detecting amyloid plaques is crucial for early diagnosis of protein disorders like Alzheimer's disease. The use of hemicyanine-based probe LDS730, belonging to the Near-Infrared Fluorescence family, provides higher precision, prevents photo-damage, and minimizes autofluorescence. The sensor exhibits a 110-fold increase in fluorescence turn-on emission when bound to insulin fibrils, making it highly sensitive with great potential for early detection and improving diagnostic accuracy.

Summary: The aggregation behavior of 4-dodecylbenzene sulfonic acid (DBSA) in water was investigated, revealing a micelle-to-vesicle transition driven by increased concentration. The DBSA vesicles exhibit stability, size-selective permeability, and can increase in size and form multilamellar vesicles during wet-dry cycles. Wet-dry cycles induce structural transitions in the DBSA vesicles and have a significant impact on their properties.

Summary: The study reveals nanoscale heterogeneities in FUS condensates and their evolution over aging using multidimensional super-resolution microscopy tools. Hydrophobic nanodomains and amyloid aggregates are identified at the condensate surface, which significantly impede local diffusion. These nanoaggregates progressively expand on the condensate surface upon aging or mechanical shears, leading to a growing low-diffusivity shell while maintaining diffusion in the condensate interior.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Summary: This research developed an effective approach to enhance the charging rates of lithium ion batteries (LIBs) by strategically incorporating carbon nanotube (CNT) conductivity boosters into Li4Ti5O12 (LTO) electrodes. Multi-layer architectures comprising CNT-rich and CNT-free LTO electrode layers were manufactured using a layer-by-layer spray coating method to promote charge transfer kinetics of high mass loading electrodes. The best performing multi-layer was paired with a spray-coated LiFePO4 (LFP) positive electrode, resulting in attractive power performance that outperformed conventional LTO || LFP combinations.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
