Summary: Acetylated Kraft lignins were used to structure vegetable oils into oleogels. Microwave-assisted acetylation at higher temperatures resulted in gel-like oil dispersions with improved viscoelastic properties and stronger shear-thinning character, along with enhanced long-term stability. The modified lignins enhanced the stability of water-in-oil Pickering emulsions by enhancing hydrogen bonding between the oil and nanoparticles.

Summary: A new Pickering emulsion system utilizing surfactant particles as stabilizers responded to external factors such as pH and metal ligands. The system exhibited long-term stability in a wide temperature range and high ionic strength resistance. The reversible transformation between emulsions stabilized by rhamnolipids and Rha-Cu particles could be conveniently manipulated by changing pH or introducing metal ligands, showing potential advantages in application fields requiring convenient transitions between emulsified and demulsified forms.

Summary: The origin of Pickering (emulsion) stabilization through the use of particles on interfaces is revisited, focusing on early papers and patents and their significance. The slow growth of Pickering emulsification throughout the twentieth century is detailed, along with its renaissance at the turn of the millennium. This revival is likely correlated with the important growth stage of colloidal physics, leading to the explosion of materials science and engineering. The extensive applications since the 1980s and prospects for future developments are also summarized.

Summary: To address health and ecological concerns, the cosmetic and pharmaceutical industries are seeking to design surfactant-free emulsions. Pickering emulsions, stabilized by colloidal particles, show promise in this regard. This article explores the use of three different types of particles (neutral, anionic, and cationic), either alone or in binary mixtures, as stabilizers for Pickering emulsions. The study focuses on the influence of particle charge on emulsion properties and the synergies between different types of particles.

Summary: Nanotechnology is a promising method to overcome the limitations of native-state lignin and enable its high-value application. Lignin nanoparticles produced using electrospray have uniform size, regular shape, and high yield, and can efficiently stabilize oil-in-water (O/W) Pickering emulsions. These nanoparticles exhibit broad-spectrum UV resistance and green antioxidant properties, and show high safety for topical products according to in vitro cytotoxicity tests. Moreover, they maintain UV-resistant ability even at low concentrations, overcoming the issue of unfavorable dark colors associated with traditional lignin-based materials. Overall, lignin nanoparticles not only act as stabilizers at the water-oil interface but also realize the high functionality of lignin.

Summary: This study investigated the use of a polyol solvent to increase the solubility of quercetin, and its incorporation into SiO2-stabilized double emulsions. The results showed that increasing the concentration of quercetin improved the viscosity, droplet size, and storage stability of the emulsions. Additionally, the quercetin interacted with SiO2 through hydrogen bonding, contributing to the stabilization of the interface and formation of a network structure that enhanced emulsion stability.

Summary: Lignin, as the most abundant source of renewable aromatic compounds on the planet, has the potential to replace petroleum-based chemicals and products, attracting increasing scholarly attention. However, its heterogeneity at different levels prevents its full utilization. Finding a general preparation method to achieve the integrated utilization of lignin molecules at all levels is the key to solving this problem. Therefore, a comprehensive understanding of the assembly behavior of lignin in different solvents is of great scientific importance.

Summary: The hydrophilicity of nanocellulose prevents interactions with the oil phase in Pickering emulsions, which is addressed by incorporating lignin nanoparticles (LNPs) as co-stabilizers. The addition of LNPs decreases oil droplet size and slows creaming, except at pH 3 and with LNP cationization which leads to droplet flocculation and rapid creaming. LNPs, applied prior or simultaneously with nanocellulose, improve interactions with the oil phase and enhance stability. The resulting Pickering emulsions can be freeze-dried to recover a solid macroporous foam that acts as an adsorbent for pharmaceutical pollutants. Overall, LNP addition allows the tailoring of properties for nanocellulose-based Pickering emulsions and foams, providing a unique and green approach to stabilize biphasic systems using bio-based nanomaterials without tedious and costly modification procedures.

Summary: This study synthesized biochar based on sapropel and investigated the effects of chemical modification on its textural characteristics, acid-base properties, and adsorption properties. The results showed that the chemical modification increased the fraction of micropores, specific surface area, and changed the surface properties of biochar. The experiment also revealed that biochar pretreated with alkali exhibited the maximum adsorption capacity for copper ions. A conceptual model identifying the mechanisms of copper adsorption on sapropel-based biosorbent was proposed.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
