“…Moreover, it has been theorized that silver ions enhance the generation of reactive oxygen species (ROS) by interacting with the thiol groups on the respiratory chain enzymes or by directly interacting with and inhibiting the action of free radical scavenging enzymes, such as superoxide dismutase. This results in an increased presence of ROS, which attack membrane lipids and DNA, resulting in faulty replication. , …”

The growing demand for efficient and economical cooling in both indoor and outdoor applications, especially personal cooling in outdoor environments, is a major challenge globally today. Passive daytime radiative cooling technology with spectral selectivity which operates by transferring radiative heat into cold universe (∼3 K) through the atmospheric window (8−13 μm) is an emerging and sustainable cooling technology. However, passive daytime radiative cooling materials are still limited by nondegradable, finite categories and single function. In this paper, multifunctional biobased poly(lactic acid) (PLA)/poly(butylene succinate) (PBS) nanofiber membranes with radiation cooling, electrical conductivity, and antibacterial properties were prepared by electrospinning technology combined with spraying technology. This multifunctional nanofiber membrane has high solar reflectivity (82%) and strong mid-infrared emissivity (98%) that achieves a temperature drop of 5.5−12 °C on sunny days and 2.9−10 °C on cloudy days. Adding 18.2% silver nanowires can reduce the resistance of the nanofiber membrane to 208 Ω, which also endowed the membrane with good antibacterial properties. This multifunctional nanofiber membrane opens up an environmentally sustainable approach for personal thermal management and introduces new possibilities for the rational design of next-generation smart textiles.

To address increasingly pressing ecological, energy, and resource challenges, there is an urgent need to develop and utilize renewable resources, in particular the exploitation of polymeric materials in marine and terrestrial organisms. This study focuses on a bottom-up preparation process to achieve uniform mechanical strength in all dimensions. Micron and nanoscale oxidized cellulose fibers were prepared through etching and oxidation techniques. Cross-linking metal ions with oxidized celluloses and alginate polysaccharides established a 3D crosslinking system. The flame retardancy of composite woods was evaluated using the limiting oxygen index (LOI) and cone calorimetry (CONE). With an LOI value of 30%, the composite wood exhibited a remarkable increase in fire resistance capability, surpassing the LOI value of natural wood (18%) by a significant margin. Furthermore, the composite wood exhibited a considerably lower minimum total heat release (THR) (5.35 MJ m −2 ) compared to natural wood (12.82 MJ m −2 ). To conduct a qualitative analysis of the molecular structures found in the pyrolysis products, the researchers employed pyrolysis gas chromatography/mass spectrometry (PY-GC/MS). The study's findings indicated that carbon dioxide emerges as the primary product. Consequently, these findings suggest that the composite wood exhibits outstanding flame-retardant properties, rendering it suitable for diverse applications in everyday environments.
