“…This result is consistent with previous reports, in which the polar coating layers could lead to the decrease in interfacial resistance. [ 34–36 ] The introduction of polar modification layers could improve the wettability with the polar solvent and enhance the close contact between electrodes and separator, which could contribute to the migration of lithium ion and decrease in the interfacial resistance.…”

The coating method of Al2O3 nanoparticles has been widely applied to promote the thermostability and wettability of polyolefin separators. However, the untreated Al2O3/polyethylene (PE) composite separators still need to improve the ionic conductivity (σ) and lithium‐ion transference number (tLi+). Herein, a method is found to obtain amino‐functionalized Al2O3 nanoparticles (N‐Al2O3). As a result, the cell with the N‐Al2O3/PE composite separator has improved σ (0.39 mS cm−1) and tLi+ (0.49). The LiCoO2/Li half‐cell based on N‐Al2O3/PE composite separator exhibits higher discharge capacity (125 mAh g−1) and better cycle performance under the current density of 1 C. Furthermore, the cell containing N‐Al2O3/PE composite separator has a better rate performance and the discharge capacity still maintains 75 mAh g−1 at a high rate of 4 C. This method is effective and simple to modify the PE separator with the amino‐functionalized Al2O3 nanoparticles and enhance the high rate performance of Li‐ion batteries.

“…Random lasing action arising from electrospun nanofibers, which act as the scatterers, doped with appropriate gain medium, has been recently studied as reported in refs 30–34 introducing a new class of flexible RLs. Cellulose – the most reported and common biopolymer in the world and the widely used in the ester form (in the present case cellulose acetate - CA) 35,36 are important and relevant building blocks with a plenty of green credentials for different applications. Moreover, the use of devices in nanoscale regime 37 offers a diversity of new applications for these nanostructured materials.…”

We report an alternative random laser (RL) architecture based on a flexible and ZnO-enriched cellulose acetate (CA) fiber matrix prepared by electrospinning. The electrospun fibers, mechanically reinforced by polyethylene oxide and impregnated with zinc oxide powder, were applied as an adsorbent surface to incorporate plasmonic centers (silver nanoprisms). The resulting structures – prepared in the absence (CA-ZnO) and in the presence of silver nanoparticles (CA-ZnO-Ag) - were developed to support light excitation, guiding and scattering prototypes of a RL. Both materials were excited by a pulsed (5 Hz, 5 ns) source at 355 nm and their fluorescence emission monitored at 387 nm. The results suggest that the addition of silver nanoprisms to the ZnO- enriched fiber matrix allows large improvement of the RL performance due to the plasmon resonance of the silver nanoprisms, with ~80% reduction in threshold energy. Besides the intensity and spectral analysis, the RL characterization included its spectral and intensity angular dependences. Bending the flexible RL did not affect the spectral characteristics of the device. No degradation was observed in the random laser emission for more than 10,000 shots of the pump laser.
