Summary: Self-compacting concrete (SCC) is widely used due to its high-performance, which is attributed to the integral stability of its components driven by the cement paste rheology and viscosity of the overall suspension. This study explores that the stability of self-compacting cement mortar depends not only on the cement suspension viscosity but also on the yield stress of the cement paste. Higher yield stress pastes result in more stable suspensions, while lower yield stresses lead to unstable mortars with higher segregation. No correlation is found between rheological parameters and bleeding.

Summary: The study uncovers the principles of self assembly driven by hydrophilic dextran brushes and charged poly(3-acrylamidophenyl boronic acid), developing three inflammatory microenvironment responsive micelles as potential Alzheimer's disease treatments. In vivo, the combination nanosystems of CEL/IBU and CEL/TEL suppress glial activation, reduce inflammatory mediators, and improve spatial memory ability in a senescence-accelerated mouse model. This inflammation responsive combination nanosystem shows promise as a new potential treatment for clinical patients with AD.

Summary: We present a dual-responsive block copolymer system that can control the size and morphology of self-assembled nanostructures through pH-dependent cloud point (Tcp). By incorporating a pH- and temperature-responsive monomer, 2-(dimethylamino)ethyl methacrylate (DMAEMA), in the nanoparticle corona, the relative hydrophilic/hydrophobic block volumes can be controlled. Varying the pH, temperature, and content of DMAEMA, we successfully generated micelles, worms, and vesicles from a single block copolymer composition.

Summary: This study demonstrates the importance of controlling interfacial chemistry in material systems. By fine-tuning the surface chemistry of silica nanoparticles, their colloidal stability and assembly at oil-water interfaces can be controlled. The study shows that the colloidal stability of the particles is influenced by the silane-grafted layers and surface roughness. The assembly of the particles at the interface is driven by electrostatic interactions.

Summary: The relationship between interfacial behavior and emulsion stability of coconut globulin (CG) at different pH levels was investigated to understand its emulsification mechanism. The dynamic interfacial tension of CG was lowest at pH 11, followed by pH 9, 3, 7, and 5. CG showed the best interfacial adsorption at pH 5 but desorption at pH 11. Heating resulted in decreased adsorption for all pH groups. The dilatational elasticity modulus (Ed) of CG was highest at pH 5, followed by pH 3, 7, 9, and 11, but significantly decreased after heating.

Summary: This study investigated the effects of ultrasonic power and gelatin concentration on the interfacial and emulsifying properties of cellulose nanofibrils (CNF). The results showed that ultrasonic treatment improved the wettability and stability of CNF at the oil-water interface. The addition of gelatin further enhanced the stability of CNF-stabilized emulsion. This study provides a theoretical basis for the regulation of CNF's interfacial and emulsifying properties.

Summary: Lignin-containing cellulose nanofibrils (LCNFs) were prepared via TEMPO-mediated oxidation and high-pressure homogenization, and the impact of carboxyl content on the properties of LCNF gel was investigated. It was found that increasing carboxyl content led to decreased lignin content, improved colloidal stability and water contact angle, as well as smaller fibril size, but slightly lower thermal stability. In addition, incorporating LCNFs into a ductile polymer matrix significantly enhanced the tensile strength.

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.
