Summary: The study investigated the bioactivity and gelling properties of a carbohydrate-rich algal extract obtained from locally harvested Ascophyllum nodosum seaweed using a chemical-free approach, with a focus on its potential in food applications. Physicochemical characterization and compositional analysis confirmed the presence of alginates and fucoidans, with laminarin as the main polysaccharide, along with significant phenolic compounds and antioxidant activity. The extract showed promising prebiotic potential by promoting the growth of beneficial bacteria, and its gelling properties were optimized for hydrogel bead formation in CaCl2 solutions. Further enrichment with alginate improved the mechanical properties of the obtained gels.

Summary: In this study, the formation mechanism of 135 different inorganic nanotubes formed by the intrinsic self-rolling driving force in asymmetric 2D Janus sheets was investigated using Density Functional Theory. The lattice mismatch or difference in chemical bond strength between inner and outer atomic layers was found to be the driving force behind the formation of inorganic nanotubes, depending on whether the Janus sheets were isovalent or non-isovalent. Moreover, over 100 tubes with a preferred radius below 35 angstrom were identified, which may exhibit distinctive properties compared to their parent 2D monolayers.

Summary: This study observes the synergistic solubility enhancement of poly(methyl methacrylate) (PMMA) in ethanol/water mixtures in the presence of benzoic acid (BA). SAXS and 2D correlation Raman experiments reveal strong interaction between PMMA chains and BA molecules through hydrogen bonding and dispersion interactions, leading to spontaneous chain extension. Crystallized stereo-irregular alpha-PMMAs are formed by spray-induced rapid solidification process in PMMA/BA/ethanol/water solutions, resulting in films composed of microfibrils with clear melting transitions and in-plane diffraction patterns.

Summary: In this study, a sustainable and recyclable biopolymeric composite hydrogel was developed by incorporating activated carbon (AC) into the alginate matrix for efficient removal of emerging pharmaceutical pollutants in industrial wastewater and environmental water samples. The activated carbon was prepared from spent granular carbon of a reverse osmosis (RO) plant using simple physicochemical methods. The composite hydrogel (AC-SGC@SA-HHB) exhibited specific surface morphology, area, and porosity, which were characterized using scanning electron microscopy (SEM) and BET analysis. The adsorption capacity of the hydrogel for tetracycline (TC) was determined and various experimental variables were investigated to study their effects on the adsorption capacity. The recyclability and versatility of the hydrogel for the removal of both organic (dyes) and inorganic (ions) pollutants were evaluated, and the practicality of the hydrogel for TC removal from real water sources and industrial effluents was assessed using the standard addition method.

Summary: Layered double-hydroxides (LDHs) have been extensively researched for their advantages in lithium-ion batteries (LIBs), but their poor electronic conductivity, volume change, and ion diffusion limitations hinder their performance. To overcome these challenges, expanded graphite (EG) was used as a conductive additive to anchor Ni2Co-LDH on its surface. The resulting Ni2Co-LDH/EG composites exhibited significantly enhanced charge-storage capacities and battery-like behavior. Density functional theory (DFT) calculations suggest that the stable Li-ion intercalation in Ni2Co-LDH/EG is attributed to the interaction energy and overlap of lithium and carbon.

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.
