“…Subsequent measurements by other researchers from three different laboratories have demonstrated that natural silk has the lowest impedance, compared to cotton or cotton/polyester mixtures with different thread counts per inch (tpi) [25]. For mask performance, impedance is important because it relates directly to the comfort and breathability of the material.…”

Silk continues to amaze. This review unravels the most recent progress in silk science, spanning from fundamental insights to medical silks. Key advances in silk flow are examined, with specific reference to the role of metal ions in switching silk from a storage to a spinning state. Orthogonal thermoplastic silk molding is described, as is the transfer of silk flow principles for the triggering of flow-induced crystallization in other non-silk polymers. Other exciting new developments include silk-inspired liquid–liquid phase separation for non-canonical fiber formation and the creation of “silk organelles” in live cells. This review closes by examining the role of silk fabrics in fashioning facemasks in response to the SARS-CoV-2 pandemic.

“…The efficiency can be further increased by increasing the number of fabric layers. However, more fabric layers increase the breathing resistance making the mask uncomfortable for use (Drewnick et al, 2020;Hancock et al, 2020;Konda et al, 2020;Zangmeister et al, 2020).…”

Respiratory protection devices such as face masks and respirators minimize the transmission of infectious diseases by providing a physical barrier to respiratory virus particles. The level of protection from a face mask and respirator depends on the nature of filter material, the size of infectious particle, breathing and environmental conditions, facial seal, and user compliance. The ongoing COVID‒19 pandemic has resulted in the global shortage of surgical face mask and respirator. In such a situation, significant global populations have either reused the single‒use face mask and respirator or used a substandard face mask fabricated from locally available materials. At the same time, researchers are actively exploring filter materials having novel functionalities such as antimicrobial, enhanced charge holding, and heat regulating properties to design potentially better face mask. In this work, we reviewed research papers and guidelines published primarily in last decade focusing on, (a) virus filtering efficiency, (b) impact of type of filter material on filtering efficiency, (c) emerging technologies in mask design, and (d) decontamination approaches. Finally, we provide future prospective on the need of novel filter materials and improved design.

Background The COVID‐19 pandemic has resulted in many live events being canceled or held without spectator participation. As a result, a series of investigations were carried out and strategies developed to determine the requirements under which cultural activities can be maintained. This work summarizes published studies and provides recommendations for performing cultural events under pandemic conditions. Methods The available literature search was evaluated in accordance with Preferred Reporting Items for Systematic Reviews and Meta‐Analyses. The results were combined with findings, guidelines, and regulations for conducting courses in other indoor environments under pandemic conditions, for example, school classrooms. Recommendations were derived, the consideration of which can enable the continuation of cultural events. Results The published studies can only take into account the previous conditions of the pandemic situation with the known virus mutations. However, the number of experimental investigations including analytical and medical proof of infections, surveys, and simulations is comparatively small. This is due to the complexity of the events as well as the priority and urgency of the school issue. Cultural events take place under very different conditions. It is therefore practically impossible to predict the risk of infection for a specific situation with many potential virus spreaders attending or to derive general rules that go beyond the known measures of vaccination, testing, masks, and distance. Conclusion Cultural events can be held under pandemic conditions provided certain requirements are met. Most study results agree on this. Any recommendations on hygiene, safety, and ventilation measures in cultural facilities under pandemic conditions can reduce the risk of infection but cannot completely eliminate it. It is also of considerable importance that visitors protect themselves individually and act responsibly.
