Summary: The study investigated two organic compounds as corrosion inhibitors for mild steel in neutral NaCl solution. Results showed that the addition of SDS and DMImCl could decrease the corrosion rate and increase the inhibition efficiency. Analysis from electrochemical tests indicated that these organic compounds adsorb on the mild steel surface to form a protective film, leading to corrosion inhibition.

Summary: A new strategy for direct access to fully substituted polycyclic imidazolium salts using alpha-enaminones and proline as the reagents is reported. This open-flask operation is a catalyst-, metal-, and Lewis acid-free green process, which does not require an ion-exchange step. It can produce good yields with minimal formation of side products, and is not limited to aryl substituents.

Summary: Knowledge of frontier orbital energies, such as HOMO and LUMO, is crucial for studying stability, corrosion inhibition potential, and reactivity of compounds. Density functional theory (DFT) calculations provide an approach to estimate these energies, but it becomes computationally intensive for large-scale screening. In this article, a machine learning model based on extreme gradient boosting is developed to predict HOMO and LUMO energies, resulting in significantly reduced computational time.

Summary: The aerobic oxidation of lignin model 2-phenoxyacetophenone (2-PAP) in cooperative ionic liquid mixtures (CoILs) with [C(2)C(1)im]OAc and [B(Z)C(1)im]NTf2 was investigated. The CoILs showed higher conversion and product yields compared to pure ILs, indicating the cooperative effects of the two ILs. [C(2)C(1)im]OAc promoted the catalytic cleavage of aryl-ether bonds and solvation, while [B(Z)C(1)im]NTf2 induced the formation of alkyl radicals and enhanced the product selectivity.

Summary: An integrated approach combining various techniques was used to study the hydrophobic eutectic solvent formed by BHT and MEN. The study showed that the hydroxyl group of BHT has little impact on the thermal behavior of the eutectic. No hydrogen bond interactions were observed for BHT due to steric hindrance, while strong hydrogen bonds were formed between MEN molecules. The three-dimensional arrangement of the components indicated a high degree of structural order, suggesting that apolar-apolar attraction is the driving force of eutectic formation.

Summary: Cellulose derivatives are widely used in composite materials to enhance mechanical performance. Adding cellulose to cement-based materials can affect the rheology, hydration, and mechanical properties of the mixture. In this study, cellulose was oxidized and functionalized to produce multifunctional nanocellulose additives for mortar. The addition of oxidized nanocellulose resulted in improved microstructure and durability of the mortar, with decreased porosity, smaller pore size distribution, increased compressive resistance, and decreased water absorption coefficient.

Summary: The traditional use of organic solvents is being rethought due to their high volatility, toxicity, and interaction with biological membranes. Green Chemistry focuses on developing sustainable and cost-effective solvent alternatives such as Ionic Liquids (ILs), bio-based solvents, and natural deep eutectic solvents (NADESs). This study screened 15 NADESs for ecotoxicity using marine and freshwater bioassays, finding no toxicity to invertebrates but potential biostimulation effects on algae. However, the intentional or accidental release of NADESs into aquatic systems may pose risks to ecosystem functioning.

Summary: Dispersion coating is an alternative to extrusion coating for coated paper packaging. In this study, two styrene-butadiene-based dispersion coatings filled with different amounts of kaolin were rod-coated on two paper substrates. The kaolin-containing formulations showed good moisture and grease barrier properties, with the best formulation involving 20% kaolin by weight. Compared to commercial coatings, the kaolin-filled coatings greatly improved grease barrier while achieving similar moisture barrier.

Summary: An in-depth study was conducted on the hydrophobic eutectic mixtures formed by l-menthol with BHT, TBC, and PC compounds. Thermal characterization revealed that the BHT/MEN system behaved as an ideal eutectic, while the TBC/MEN and PC/MEN mixtures exhibited the properties of type V deep eutectic solvents. The formation of hydrogen-bond interactions in the BHT/MEN mixtures was hindered due to steric hindrance in the BHT molecule, whereas the TBC-MEN and PC-MEN mixtures were driven by the donor-receptor H-bond and self-association through H-bonded networks, respectively. This study provides valuable insights into the structure-properties relationship of deep eutectic solvents.

Summary: The environmental impact of industrial technologies and related remediation methods is a significant research area. In the development of materials for wastewater treatment or air purification, the use of hazardous reactants often diminishes the overall positive contribution to the environment. This study presents the synthesis of stable titanium dioxide (TiO2) sols using an environmentally friendly method. The sol was deposited on glass and evaluated for wastewater purification ability by photocatalytic degradation of organic dyes. The results showed high efficiency and reusability, with degradation rates exceeding 85% for Rhodamine B and 100% for Methylene Blue.

Summary: Dispersion coatings are offered as alternative solutions to extrusion coating technology for paper-based packaging. In addition to providing barrier properties, waterborne dispersions may implement the processing and converting properties of coated substrates, which are of extreme interest for an effective transfer to the industry. This study formulated styrene-butadiene-based aqueous dispersions with different amounts of kaolin as pigment and compared their heat-seal ability, fold cracking resistance, and blocking tendency against commercial dispersion coating grades. The results showed that kaolin content dominated the sealing behavior of the experimental formulations, while commercial grades were mostly affected by temperature. Increasing kaolin content improved moisture barrier performance but also increased fold cracking.

Summary: In this study, a spray drying process was used to produce nanostructured microsponges from TEMPO oxidized cellulose nanofibers (TOCNF). Different formulations were prepared by adjusting the oxidation degree of the nanofibers and the ratios of crosslinkers. The microsponges obtained from TOCNF with the highest carboxylic group content showed good colloidal stability and desired particle size. The microsponges were chemically characterized and exhibited pH-responsive swelling and drug release behavior. Moreover, the microsponges derived from formulations without citric acid were found to be biocompatible based on in vitro tests on gastric cancer cells.
