Additionally, attempts were made to synthesize polymers with higher molecular weight and consequently higher rheological properties. Acrylamide (AM) was copolymerized with 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS) and three hydrophobic monomers of styrene (St), N-para-ethylphenylacrylamide (EφAM), and N-benzylacrylamide (BAM) using the micellar polymerization method to optimize the rheological properties of drilling fluids. The synthesized terpolymers were characterized using FT-IR and ¹H NMR techniques, confirming successful polymerization. Rheological properties were evaluated under various conditions, alongside dynamic light scattering (DLS), to investigate the relationship between the polymers’ microstructure and the viscosity of their aqueous solutions. The rheological behavior of the fluids was studied in tap water, divalent salt (CaCl₂), and monovalent salt-saturated water (SSW), both before and after hot rolling at 250°F for 4 h. All polymer fluids showed shear-thinning behavior. After hot rolling, the polymers showed improved performance in deionized water, but their properties declined in salt-saturated water. The polymer containing the EφAM monomer demonstrated exceptional resistance to shear, salt, and high temperatures due to its unique structure and high hydrophobicity, that making it suitable for drilling fluid applications. To enhance the molecular weight and rheological properties, the optimal polymer was re-synthesized with adjustments to the initiator amount and monomer concentration. The modified polymer, AMAE’’_8.1, showed enhanced resistance in salt-saturated water and exhibited properties similar to natural polymers, such as xanthan gum.</div></div>","PeriodicalId":371,"journal":{"name":"Journal of Molecular Liquids","volume":"429 ","pages":"Article 127585"},"PeriodicalIF":5.3,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143858739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While significant progress has been made in understanding single cavitation bubble, research on multi-bubble interactions remains notably underexplored. To understand the characteristics of multi-cavitation bubble collapse and inter-bubble interaction, the paper studies the microscopic characteristics in the free domain based on the coarse-grained force field. It considers factors such as bubble radius, bubble distance, and whether the bubbles contain gas or not to reveal the morphology, local density distribution, and velocity distribution change of double bubbles. Results show that as the bubble radius increases, the local density changes are more prominent, and the collapse time and the depression depth increase. The jet is more likely to face the side of double bubbles facing each other during formation, and the jet deflection angle also gradually increases. As the bubble distance increases, the jet deflection angle decreases. The larger the initial radius of the gas-containing double bubble, the more dispersed the nitrogen is, and eventually small water-insoluble bubbles such as mushroom, umbrella, and curved moon are formed. What’s more, gas-containing double bubbles collapse at a slower rate than non-gas-containing double cavitation bubbles, and the gas attenuates the collapse effect.</div></div>","PeriodicalId":371,"journal":{"name":"Journal of Molecular Liquids","volume":"429 ","pages":"Article 127517"},"PeriodicalIF":5.3,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143859426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This distribution reduces attraction between ion pairs and balances the energy between them, facilitating the formation of an IL. In this work, we designed the ILs containing the natural anions and cations. In the designed ILs, the anions contain various amino acids and sugars, and the cation contains methylated DNA base adenine. Our study has focused on intramolecular hydrogen bonding (H-bond) within the anion and intermolecular H-bond between methylated adenine cation and the various anions. Our objective in creating these structures is to investigate H-bonds’ influence on the negative charge distribution in the anion and to explore the anomeric effect on the stability of the cation in the designed ILs. In particular, using quantum mechanics (QM) calculations, we examined how intermolecular H-bonds affect the interaction energy between the ions in our newly designed ILs. At the same time, molecular dynamics (MD) simulations were utilized to validate the QM results. The QM average interaction energy (Δ<em>E_int</em>) between the anion and cation of the designed ILs is −73.39 kcal/mol, consistent with the Δ<em>E_int</em> typically reported for the common ILs.

This structured approach clearly outlines significant findings regarding the impact of DESs and NADES on proteins structure and function with emphasis on their mechanisms. DESs and NADES can significantly influence protein structure through solvent–solute interactions that may stabilize or destabilize proteins depending on their components. Many proteins show enhanced solubility in DESs and NADES due to favorable interactions with the solvent’s hydrogen-bonding network. The effect of DES and NADES on thermal stability varies; while they may not inherently increase stability, they can provide protective environments against denaturation under certain conditions. Enzymes can maintain active in DES and NADES, although optimal conditions vary for each enzyme-substrate pair.

The novel DESs represent binary mixtures of menthol (MEN) and diamines (hexyl-ethylene-diamine, HEX, and nonyl-ethylene-diamine, NON,). The simulations revealed that both DESs exhibit a higher affinity to CO₂ rather than to H₂S due to larger partial atomic electrostatic charges on the oxygen atoms. The increase in pressure resulted in a linear boost in the gas capacities of HEX/MEN and NON/MEN. In turn, no synergistic effect was detected while investigating CO₂/H₂S simultaneous absorption. The performance of HEX/MEN as an absorbent is somewhat higher as compared to that of NON/MEN in the case of H₂S and within the computation uncertainty in the case of CO₂.
