Summary: Alginates were studied for their ability to form complexes with beta-lactoglobulin at different pH levels and varying ratios of M and G residues. The results showed that pH and M content influenced the binding capacity and size of the particles, providing insights for designing alginate-protein particles in acidic environments.

Summary: Alginate lyases are enzymes that catalyze the depolymerization of alginate, a linear polysaccharide. In this study, two alginate lyase genes were cloned and expressed from a marine thermophilic bacterium. The recombinant enzymes showed high thermostability and activity at elevated temperatures. The NMR analysis revealed that one of the enzymes is an endolytic lyase, while the other is an exolytic lyase.

Summary: The study found that ocean acidification can have specific effects on the exoskeleton of female southern Tanner crabs, including reduced microhardness, changes in elemental content, structural integrity, and phase of calcium carbonate. These effects varied in different body regions and highlight the vulnerability of long-lived crabs like C. bairdi to ocean acidification due to limited capacity for repair.

Summary: This study investigated the neuroprotective effects of brown seaweed polysaccharides on Parkinson's disease pathogenesis, finding that polymannuronic acid showed better neuroprotection compared to polyguluronic acid and alginate. Polymannuronic acid improved motor functions and prevented dopaminergic neuronal loss by increasing tyrosine hydroxylase expressions, while polyguluronic acid and alginate showed different effects on inflammation and neurotransmitter levels in Parkinson's disease mice.

Summary: The study found that casein-assisted enzyme-induced carbonate precipitation showed better performance in enhancing the compressive strength of biocemented specimens. Experimental optimization led to precipitates achieving a maximum compressive strength of 2 MPa under optimized conditions. Casein-assisted EICP treatment was more efficient in promoting the formation of low-level CaCO3 precipitation compared to skim milk.

Summary: This study demonstrates that alginate gel rapidly under ambient conditions through calcium mediated electrostatic crosslinks, forming protective matrices for sensitive bioactive cargo. The crosslinking in CLAMs plays a crucial role in determining its barrier properties and applications in food, cosmetics, and agriculture. The extent of gelation in spray dried CLAMs can be controlled by the molecular weights of the alginates at saturating calcium concentrations.

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 study presents a novel heterojunction structure (SrTiO3/CN-TAL10.0) for enhanced photocatalytic water splitting (PWS). The incorporation of thiophenedicarboxaldehyde (TAL) through copolymerization significantly improves the photocatalytic activity of carbon nitride (CN) while maintaining its photostability performance. The optimized composition allows efficient isolation of photoinduced charge carriers and enhanced charge transport, resulting in a remarkable increase in overall photocatalytic efficiency.

Summary: Understanding the interactions between polymers and surfactants is crucial for optimizing commercial systems. This study tested the behavior of polymer-surfactant systems, revealing that they do not behave like polyelectrolytes in the presence of salt. Additionally, the structure of polymer-surfactant complexes under confinement differs from that of polyelectrolytes.

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.
