Summary: In this study, a versatile antibacterial coating was successfully synthesized using mussel-inspired dopamine-modified sodium alginate. The coating demonstrated excellent adhesion properties and antibacterial effects on cotton fabric, aluminum sheet, and polyurethane membrane. The coated cotton fabric exhibited ideal hydrophilicity and increased liquid absorption capacity with more coating layers. The coated materials effectively inhibited the growth of Escherichia coli and Staphylococcus aureus, and maintained their antibacterial ability even after multiple cycles of antibacterial trials or washing. The coated cotton fabric also showed hemostatic effects without significant hemolysis or cytotoxicity. The results suggest a promising approach for developing antibacterial coatings for different substrate surfaces.

Summary: In this study, five composites based on metals (Ag, Fe, Cu) and ceramic were prepared using the solid-state sintering method. Two different phases of wollastonite were identified in all composites. The in vitro bioactivity assay showed that all composites, except the one with >0.1% Ag concentration, exhibited bioactive behavior. The antibacterial activity test demonstrated that all samples except the 0.2 Fe sample had antibacterial activity, with the 0.1Ag-0.1Cu and 0.1Ag-0.1Fe composites considered as the optimal composites due to their superior bioactivity and antibacterial efficacy.

Summary: A new organic inorganic hybrid compound, [TPA](2)CoBr4, has been synthesized and characterized in terms of its crystal structure, thermal properties, and electrical behavior. The compound exhibits a structural phase transition at around 394 K, which is accompanied by a change in electrical conduction mechanism. The frequency and temperature-dependent electrical properties suggest a relaxation phenomenon and semiconductor-type behavior in the material.

Summary: Tertiary fatty amide DBUA is a promising eco-friendly plasticizer for PVC, which can improve the elasticity and elongation at break of PVC films, as well as reduce the glass transition temperature of PVC. DBUA exhibits good plasticizing efficacy towards PVC, but has a negative impact on thermal stability and migration. In addition, DBUA also shows higher biodegradability.

Summary: A new proton conducting membrane was developed by impregnation of porous polyimide Matrimid (R) (PI) with hydrophobic protic ionic liquid triethylammonium bis(trifluoromethylsulfonyl)imide (TEA-TFSI). The mechanical properties of the membrane were improved by impregnating it with the solution of polyetheramine Jeffamine (R) D-400 in the TEA-TFSI. The resulting partially cross-linked PI showed promising performance as a polymer electrolyte membrane for fuel cells operating at elevated temperatures in water-free conditions.

Summary: This research developed low-cost proton-conducting electrolytes for fuel cells operating at high temperatures by preparing two room temperature protic ionic liquids (PILs), IM-DBP and IM-BEHP. The synthesized PILs were optimized using density functional theory and showed hydrogen bonding between the cation and anion. Both PILs exhibited low glass transition temperatures, high thermal degradation points, and viscosity that decreased with increasing temperature. The ionic conductivity of the PILs reached the desired level above 140 degrees C. The obtained results suggest that imidazolium dialkyl phosphates can be used as proton conducting electrolytes for medium temperature fuel cell applications.

This study investigated the effects of different biocides on the release of extracellular DNA (eDNA) from biofilms of Pseudomonas aeruginosa and Staphylococcus aureus. The results showed that most biocides caused substantial eDNA release, while PHMG-Cl was able to block biofilm development and inactivate DNA on surfaces.
