The cover image created by Lihua Lou et al., shows poly(vinyl alcohol) nanofiber prepared by electrospinning method. The inserted drawings represent changes in units (sub sections) within nanofiber webs under external load based on the actual tensile stress-strain curves of nanofiber webs, as hypothesized by the authors. This study also analyzes the effect of various testing parameters, as well as the interactions on the tensile properties on nanofiber webs. Results from this study, enable a comprehensive understanding of each testing parameter and their interaction effects and help with the standardization of tenacity evaluation of nanofibers.

The aging effect of the atmospheric pressure plasma jet on improvement of spinnability of poly-ε-caprolactone (PCL) is reported. The conductivity, viscosity, surface tension, pH, and polymer molecular weight of the aged solutions were analyzed and were compared with the unaged solutions. Electrospinning of the stored PCL solutions resulted in the generation of beadless PCL nanofibers having a similar surface chemical composition as nanofibers generated from unaged solutions.

At homeotropic state, the polymer stabilzied liquid crystal system (PSLC) is transparent. On application of electric field, the liquid crystal rotate to multi-domains which results in scattering of incident light. The system turns to opaque. A 40 × 50 cm² window based on PSLC has been developed in an industrial production line, which exhibits a highly transparent voltage-off state (3.5% haze) and a voltage-on scattering state (98% haze).
