Summary: In this study, femtosecond laser post-processing was used to improve the silver nanowire transparent electrodes by achieving welding between nanowires. This led to a significant reduction in sheet resistance and an improvement in the figure of merit of the electrodes. The energy density of the laser had an impact on the welding efficiency, with excessively high energy density causing nanowire melting. Additionally, laser irradiation had little effect on the transmittance of the electrodes, and the number of effective pulses did not significantly affect the welding efficiency of the nanowires.

Summary: This study examined the effects of annealing temperature on the optical, structural, surface, and morphological characteristics of CIS thin films. XRD study showed that crystallinity and intensity peak increase with increasing annealing temperature. Both Raman and XRD measurements demonstrated the increase in crystalline quality and grain size of CIS thin films as the annealing temperature rises. Annealing also led to an enhancement in grain size. The optical band gap decreases with increasing annealing temperature.

Summary: This paper proposes a versatile method for photopatterning silver nanowire networks, based on photoinduced nanowire-nanowire and nanowire-substrate cross-linking. The resulting hybrid transparent electrodes exhibit low roughness, excellent tolerance to oxidation or electrochemical processes and mechanical stability against bending, without compromising the optical/electrical characteristics achievable from the pristine silver nanowire network. The proposed method can facilitate the practical application of silver nanowire network-based transparent electrodes.

Summary: A PDMS composite with multi-walled carbon nanotubes was successfully prepared and its physicochemical properties were modified through plasma and excimer laser treatment. The changes in surface chemistry, wettability, and morphology were examined in detail. Plasma treatment followed by heating resulted in a unique wrinkle-like pattern on the PDMS surface. The impact of different laser treatment conditions on the composite surface was investigated. Morphology was analyzed using AFM and LCM techniques, while chemical changes and surface mapping were studied using the EDS/EDX method. The antibacterial activity of the activated polymer composites was evaluated against S. epidermidis and E. coli, and silver deposition and high-energy laser treatment were found to enhance the antibacterial properties.

Summary: The utilization of silver nanoparticles (AgNPs) has become widespread due to their superior properties, but this also poses the risk of irreversible environmental contamination. Plant cuticle and cell wall provide protection to internal cell structures, such as the cytoskeleton, which reacts quickly to threats and triggers defense signaling. This study found that the number and growth rate of microtubules (MTs) decreased significantly after AgNPs treatment, and the levels of stress phytohormone derivatives increased. These findings contribute to understanding the response mechanism to AgNPs and the broader physiological context of MT structure and dynamics.

Summary: This study explores the possibility of firmly anchoring silver nanoparticles (AgNPs) into polyetherether ketone (PEEK) with a tailored surface morphology that exhibits laser-induced periodic surface structures (LIPSS). The antibacterial test proved that AgNPs-decorated LIPSS represents a more effective bactericidal protection than their planar counterparts, even if they contain a lower concentration of immobilized particles. Nanostructured PEEK with embedded AgNPs may open up new possibilities in the production of templates for replication processes in the construction of functional bactericidal biopolymers or may be directly used in tissue engineering applications.
