Summary: Prevention of bacterial adhesion is important in reducing biofilm formation and associated infections. In this study, a PET film was modified with silica nanoparticles and fluorinated carbon chains to create a superhydrophobic surface. However, contrary to expectations, bacterial adhesion, specifically of E. coli YadA, increased on the modified PET surfaces. This highlights the significance of material micro topography in bacterial adhesion.

Summary: We synthesized four well-designed polysiloxane elastomers with different macromolecular structures and investigated the impact of chemical structure on the macroadhesion performance of microfibrillar adhesives. The study confirmed that the chemical structure is the major factor influencing the adhesion properties of the microfibrillar adhesives. The adhesive properties varied significantly among the four adhesives, highlighting the importance of chemical structure in determining adhesion performance. The observed differences were attributed to variations in surface free energy and molecular interactions resulting from the designed macromolecular structures.

Summary: Icing and freezing phenomena in cold weather cause serious damage and economic losses. The development of a new effective icephobic surface with low ice adhesion strength that can easily remove ice by wind or gravity force is essentially required. In this study, a silicone oil-infused oleamide-polydimethylsiloxane (SiOP) was proposed to achieve the effective icephobic performance with enhanced lubrication lifetime. The fabricated SiOP surfaces have very low ice adhesion strength and maintain their superior icephobicity for more than 30 icing/deicing cycles.

Summary: This study investigates vibration reduction of a simply supported conical shell with distributed piezoelectric sensor and actuator layers. Different piezoelectric layer distributions were considered and a PD controller was used to reduce shell vibration. Results show that derivative controllers can affect natural frequencies more and circumferential distribution has more effects on the dynamic of the conical shell.

Summary: The development of antifouling materials is crucial in various fields, such as medicine and food packaging. In this study, 2D-matrices made of different polymers were surface functionalized through aminolysis, leading to the creation of bioactive surfaces with potential applications as flexible films for food packaging. The antimicrobial activity of the functionalized surfaces was found to be related to the degree of surface functionalization and the polymers used.

Summary: This study discovered the possibility of reducing exposure time of antimicrobial photo dynamic therapy (aPDT) by combining poly-beta-amino esters (PBAEs) with toluidine blue O (TBO), resulting in inactivation rates 30 times quicker and potential for further improvements through PBAE backbone optimisation. The superior antimicrobial performance of this new approach benefits from the use of well-established, low-cost and safe dye (TBO) coupled with inexpensive, widely tested and biodegradable polymers also known to be safe. Additionally, no adverse cytotoxic effects of the PBAEs adjuvated TBO delivery have been observed, demonstrating the safety profile of this new technology.

Summary: Porous materials with nanometer-scale pores have important applications as nanoporous membranes. In this study, ABA triblock copolymers were used as precursors to produce nanoporous polymeric membranes (NPMs) in thin film form by degrading the end blocks. Polycyclooctene (PCOE) NPMs with tunable pore sizes were successfully prepared using solvent casting technique. Oxygen plasma etching was employed to improve the surface porosity and hydrophilicity of the membranes. This study provides a straightforward method to produce tough NPMs with high porosity and hydrophilic surface properties.
