Summary: The solvent-assisted lipid bilayer (SALB) formation method is a simple and efficient microfluidic-based strategy for fabricating supported lipid bilayers (SLBs) with diverse compositions on various solid supports. Through thermodynamic modeling, this study explored the effects of experimental parameters on SALB formation, including substrate surface properties, initial lipid concentration, and temperature. The results showed that all parameters are crucial for the successful formation of high-quality SLBs. The model also provides guidance for optimizing experimental conditions for lipid membrane-related applications.

Summary: The antioxidant potential of aqueous fullerene dispersions (AFD) of non-functionalized C-60, C-70, and Gd@C-82 endofullerene was evaluated through chemiluminescence measurements and mathematical modeling of long-term kinetics data. The study found that the antioxidant capacity of AFDs increased in the order Gd@C-82 < C-70 < C-60, with Gd@C-82 showing actual antioxidant action 300-fold higher than quenching constants.

Summary: Lipid droplets (LD) locate in the endoplasmic reticulum membrane and play important roles in biological functions. A protein called ADRP surrounds LDs along with phospholipid monolayers and is involved in storing neutral lipids. This article focuses on the influence of ADRP on the 3D shape of LDs embedded in bilayers and the diffusion of phospholipids on LD surfaces. The study shows that ADRP significantly affects the 3D structure of LDs. Rating: 9/10.

Summary: Curvature-mediated lipid-protein interactions play a crucial role in cellular reactions and mechanisms. This study investigates the membrane curvature partitioning behavior of cube-shaped CsPbBr3 quantum dots (QDs) embedded within deformed giant unilamellar vesicles (GUVs). The results show that the distribution of CsPbBr3 QDs differs significantly from that of conventional fluorophores and quasispherical CdSe core/ZnS shell QDs, suggesting that the geometry of both QDs and lipid membranes affect the curvature preferences of QDs. These findings provide insights into the aggregation of proteins induced by curvature and the interactions between lipid membranes and intercalating particles.

Summary: Solvent-assisted lipid bilayer (SALB) formation is a versatile approach for creating supported lipid membranes (SLBs) on metal surfaces, with lipid concentration in the solvent being a key parameter. The study found that at low concentrations, mostly monolayers are present, while at high concentrations, diverse structures coexist. The mechanism of SALB formation leads to unique two-step features in approach force curves on SLBs.

Summary: This study addresses the challenge of dendrite growth in rechargeable aqueous zinc batteries by proposing a new zinc battery electrolyte, which can form an anode protecting layer with a biomimetic lipid-bilayer structure. This layer limits anode contact with water and offers fast zinc ion transport pathways, effectively suppressing dendrite growth while maintaining high rate capability. Additionally, a stable fluorinated solid electrolyte interphase is formed, further enhancing zinc reversibility. The electrolyte enables unprecedented cycling stability with dendrite-free zinc plating/stripping and shows good capacity retention.

Summary: The study conducted molecular dynamics simulations to investigate the interaction between MXene nanosheets and a model bacterial membrane, revealing that MXene adsorption could induce a local phase transition in the membrane and lead to cell lysis. This proposed bactericidal mechanism of MXenes provides a useful model for designing new antibacterial nanomaterials.

Summary: A facile and robust strategy using cellulose in NaOH/thiourea aqueous solution is reported for the rapid and scalable preparation of homogeneous and stable CNT dispersion. The CNT dispersion is demonstrated to be suitable for aqueous self-assembly of various functional materials, ranging from zero-dimensional (0D) microsphere to three-dimensional (3D) monolith through various molding techniques. The dispersion can also be used as ink for CNT-based paper and textile, showing potential for flexible and wearable devices.

Summary: Unilamellar liposome is commonly used in lipid-protein interaction studies and drug delivery for disease treatment, while related lipid-containing nanoparticles are utilized in the development of mRNA vaccines. It has been found that only unilamellar films form in equilibrium lipid dispersions at specific temperatures dependent on the lipid identities. Thermodynamic analysis confirms that films at air-water surfaces can be employed to monitor the properties of lipid vesicles in the dispersion.

Summary: Direct ink writing (DIW) has a direct impact on the microstructure and properties of materials. However, using nanoparticles at high concentrations is limited due to dispersion difficulties and deteriorated physical properties. Research on low-viscosity nanocomposites is lacking, but aligning anisotropic particles at low nanoparticles concentrations enhances the physical properties of the nanocomposite with DIW. Using sepiolite alignment in a photocurable nanocomposite material with silicone oil complexed with fumed silica as the printing matrix is expected to significantly improve mechanical properties compared to conventional digital light processing.

Summary: Enzyme-assisted aqueous extraction (EAAE) is a green and scalable method for producing fish oil and protein hydrolysates. This study investigated the effects of different parameters on emulsion formation, oil recovery, and crude oil composition during EAAE of Baltic herring. The results showed that EAAE resulted in a lower content of phospholipids and docosahexaenoic acid compared to solvent-extracted oil. Changing the fish to water ratio and adding ethanol led to a significant reduction in emulsion formation and increased oil recovery.

Summary: An aqueous dispersion strategy using nano-scaled ligno-sulfonates was proposed to overcome the dilemma between self-healing capacity and mechanical strength for polyurethane materials. The prepared self-healing polyurethane showed an ultra-high tensile strength and elongation at break, even after undergoing thermal processing. Atomic Force Microscope (AFM) and Variable-Temperature Infrared Spectroscopy (V-FTIR) confirmed the presence of nano-scaled ligno-sulfonate aggregates and discussed the reinforcing mechanism. V-FTIR further revealed the origin of self-healing from the dissociation of oxime-carbamate bonds with increased temperature. This nano-scaled aqueous dispersion strategy has the potential to design polyurethane materials with balanced self-healing performance and mechanical properties.
