Summary: Cellular environments can alter biomolecular properties, and the effects of crowding cosolutes on macromolecules in nanoconfinement have been investigated. The study found that hexaethylene glycol (HEG) can split a telomeric G-quadruplex (GQ) into two populations with different effects, either through long-range dehydration or direct interactions. Increasing the number of HEG molecules unexpectedly decreased the stability of the GQ, indicating the dominant role of direct interactions over long-range stabilizing effects in hydrophilic nanocavities.

Summary: In this study, a zinc-based metal-organic framework/magnetic hydroxyapatite nanocomposite was synthesized and coated with a biocompatible layer of polyethylene glycol as a targeting drug delivery system. The nanocomposites were characterized and utilized as carriers to encapsulate the anticancer drug doxorubicin. Both nanocomposites showed pH-dependent drug release and the Korsmeyer-Peppas model was the best fit to describe the release mechanism. The synthesized systems showed no significant toxicity and exhibited higher toxicity against lung cancer cell lines. Additionally, the nanocomposites demonstrated excellent antioxidant activity. These findings suggest that the prepared drug systems have potential for targeted drug delivery applications.

Summary: Environmentally friendly polymer membranes for dye contamination removal were prepared from edible calcium alginate. The addition of oligoethylene glycol (OEG) or polyethylene glycol (PEG) to the casting polymer solution and subsequent removal of the OEG or PEG from the membranes through a washing process improved water permeability and tailored the mass transfer channels, resulting in membranes suitable for various membrane separation processes. These modified membranes exhibited increased water permeability and maintained molecular separation performance, making them suitable for applications in nanofiltration and ultrafiltration processes for wastewater treatment.

Summary: With the increasing demand for energy, the development of high-performing drilling fluids and additives that are environmentally compatible for shale gas formations has become crucial. The synthesis and characterization of carboxymethyl chitosan (CM-CS) was conducted, and it was used as an additive in a water-based drilling fluid system. Various tests were performed and the results showed that CM-CS improved the drilling fluid properties compared to the conventional shale inhibitor, PEG. CM-CS demonstrated minimal interaction with Indian shale samples, suggesting its suitability for drilling fluid applications in troublesome shale gas formations.

Summary: This study presents a simplified synthesis method for polyethylenimine (PEI) by using 2-haloethylamine in aqueous solution without separating the aziridine intermediate. The optimized two-stage process at different temperatures allows the conversion of 2-chloroethylamine into aziridine and PEI oligomer, and the subsequent ring-opening polymerization of aziridine to form PEI chains. The impurities in the final polymers are significantly reduced compared to traditional methods. This study provides insights into the mechanism of aziridine polymerization under basic conditions and offers a safer and more economical approach to manufacturing PEI polymers.

Summary: This study explored CaCO3 mineralization by adding a Ca(OH)2 solution to PEI-CO2 adduct solutions. The alkylammonium carbamate zwitterions in the adducts can hydrolyze to release bicarbonate ions and form CaCO3, while transforming into the polyamine structure of PEI. The PEI-CO2 polymer serves as both the CO2 source and template for vaterite CaCO3 nucleation and growth. By adding a relatively low dosage of Ca(OH)2 solution, the CO2-adducted linkages can firmly adsorb onto the growing vaterite nanocrystallites, providing long-term vaterite phase and colloidal stability. The obtained vaterite nanoparticles possess a mesoporous structure, dissolve in a weakly acidic environment, exhibit low cytotoxicity, and can effectively deliver drugs in an acid-responsive manner.

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.
