Summary: This study presents a novel antibacterial agent based on the combination of copper nanoparticles (CuNPs) and poly-pyrrole (PPy). The Cu/PPy nanocomposite, characterized by spherical CuNPs around 25 nm in diameter uniformly dispersed throughout a granular PPy matrix, was synthesized using a straightforward in situ polymerization method in water. The antibacterial activity of Cu/PPy against E. coli and S. aureus was determined, demonstrating the synergistic engagement of CuNPs and PPy. Low concentrations of Cu/PPy, such as 2 ppm with 9.45 wt% Cu content, showed significant antibacterial efficacy, indicating its potential as a safe and environmentally acceptable antibacterial agent.

Summary: Although nanostructured Si can overcome volume expansion without breakage, in practical applications, Si/C composites are used as anode in lithium batteries instead. However, volume expansion of Si easily leads to rupture of Si/C composites, causing electrical contact loss and poor cyclability. Few Si/C composites reported so far can meet real application requirements. A high-strength, high-density, isotropic Si/C composite was applied in commercial cylindrical cells with NCM811, exhibiting a capacity retention of 83.8% over 1000 cycles and 89.0% at different voltage ranges.

Summary: Solid polymer electrolytes (SPEs) based on PVDF-HFP polymer, CPT zeolite, and [Bmim][SCN] ionic liquid were prepared by solvent evaporation at different temperatures. The higher ionic conductivity and lithium transference number were achieved at room temperature and 160 degrees C. The SPE prepared at 160 degrees C showed the highest discharge capacity at C/10 and C/2 rates. The control of solvent evaporation temperature allows for optimization of solid-state battery performance.

Summary: In this study, Terfenol-D cone-like shaped nanopatterned surfaces were fabricated using sputtering, and their bactericidal effect was enhanced by an alternating magnetic field. Bacterial adhesion analysis showed a reduction of attachment surface on Terfenol-D surfaces compared to control silicon, attributed to material properties and nanostructuration. Therefore, this study presents a method to induce and/or improve the mechanical antimicrobial behavior of surfaces via application of a magnetic field, as an alternative or in combination with chemical methods.

Summary: Poly(hydroxybutyrate-co-hidroxyvalerate) (PHBV) is a biodegradable polymer that can be used as a substitute for plastics made from fossil resources. By blending PHBV with poly(caprolactone) (PCL) and poly(lactic acid) (PLA), its properties can be improved, including morphology, wetting, structure, thermal, mechanical, and electrical characteristics. The addition of PCL and PLA also enhances the antibacterial activity of PHBV. This study demonstrates the potential of developing PHBV blends with PCL or PLA for specific applications.
