Summary: This study examines the 3D structuring of cellulose nanofiber foam-based ink and the transition of foam from insulator to conductor. The colloidal stability of the foam is crucial for producing a solid template for the synthesis of conducting polymers. Liquid foam ink is prepared by stirring a CNF suspension with an emulsifier, allowing for shear-thinning behavior and flexible design of structures through 3D printing. Conductive CNF foams are prepared via in situ polymerization on solid foam, with observed topological features and conductivity investigation.

Summary: The study on using electrostatic complexation to prepare wet-resilient foams in water showed that suspensions of oppositely charged cellulose nanofibers form clusters and networks of fibers, with the balance between these structures affecting colloidal stability and rheological behavior. The foams prepared from these suspensions exhibited maximum compressive modulus at a 1:1 mass composition, indicating meaningful attractive interactions and potential hydrogen bonds and hydrophobic contacts within the clustering structure. These findings may pave the way for developing robust allcellulose materials using nontoxic chemicals in water.

Summary: This study investigated the synthesis of novel metal complexes by combining two ligands, barbituric acid (HL1) and thiobarbituric acid (HL2), with different metal chlorides (Cd(II), Co(II), Cu(II), and Fe(III) chlorides) in a 1:1:1 ratio. Various analyses, including elemental analysis and spectral analysis investigations, were conducted to confirm the obtained mixed complexes. The thermal stability of the complexes was studied using TGA analysis, while the kinetic parameters were derived using the Coats-Redfern approach. XRD pattern analysis was used to analyze the crystallinity of the metals. The investigated complexes demonstrated excellent antimicrobial and antitumor activity, with Co(II) and Cu(II) complexes showing the highest activity. Docking analysis with various proteins further confirmed this. Additionally, the stability and physical descriptors of the ligands and complexes were assessed using DFT/B3LYP/LANL2DZ basis, and the electrochemical characterization and electrocatalytic properties of the metal complexes were evaluated using cyclic voltammetry and electrochemical impedance spectroscopy.
