Applying heat and humidity using stove boiled water for decontamination of N95 respirators in low resource settings

Siddharth Doshi et al.

Summary: The study demonstrates a simple and scalable method for decontamination of N95 respirators using controlled humidity and temperature, which can be easily applied in low-resource settings. The filtration efficiency of the respirators remained above 97% after multiple treatment cycles, and the same method can also be used for surgical masks decontamination. This low-cost and reliable method can be performed without electricity access, making it globally applicable in resource-constrained settings.

Electrospun Nanofibre Filtration Media to Protect against Biological or Nonbiological Airborne Particles

Fabrice N. H. Karabulut et al.

Summary: Electrospun nanofiber filter media show superior performance in air filtration compared to melt-blown nanofibers, meeting the filtration efficiency and breathability requirements of various mask and respirator standards, such as N95 and ASTM. The outstanding uniformity of the nanofibers allows for efficient particle capture and airflow through the filter.

Effectiveness of antiviral metal and metal oxide thin-film coatings against human coronavirus 229E

Louis-Vincent Delumeau et al.

Summary: Virucidal thin-film coatings have the potential to inactivate pathogens on surfaces, with Cu and Cu2O coatings demonstrating clear virucidal behavior against HCoV-229E human coronavirus. Despite being frequently cited antimicrobial materials, Ag, ZnO, and TiO2 coatings did not show a significant reduction in viral infectivity. Additionally, Cu fabric coating on N95 respirators' polypropylene fabrics effectively reduces the virus infectivity.

Nanoparticle composite TPNT1 is effective against SARS-CoV-2 and influenza viruses

Sui-Yuan Chang et al.

Summary: The metal nanoparticle composite TPNT1, containing a combination of nanoparticles and ClO2, was found to inhibit multiple clades of SARS-CoV-2 as well as human and avian influenza viruses by blocking viral entry, interfering with syncytium formation, and reducing cytopathic effects. This composite shows potential as a prophylactic agent against both SARS-CoV-2 and other viral infections.

Fight against COVID-19: The case of antiviral surfaces

Kamyar Shirvanimoghaddam et al.

Summary: The COVID-19 pandemic is the largest global public health crisis in the 21st century so far, primarily transmitted through droplets. Regular disinfection or neutralization of the environment is essential to minimize the risk of infection. The development and application of antiviral coatings can effectively prevent the spread of viral particles.

Global View and Trends in Electrospun Nanofiber Membranes for Particulate Matter Filtration: A Review

Laura Margarita Valencia-Osorio et al.

Summary: This review examines numerous experimental works on particulate matter filtration by electrospun nanofiber membranes in the past decade, classifying and comparing different types of ESNFMs to identify the best trends. By categorizing the ESNFMs based on moments during the electrospinning process, the study reveals that charged and nanofiber/nets membranes show the most promising results for PM0.3 filtration, with high capture efficiencies (>95%) and low pressure drops (<100 Pa).

Airborne transmission of respiratory viruses

Chia C. Wang et al.

Summary: The COVID-19 pandemic has exposed critical knowledge gaps in our understanding of traditional respiratory virus transmission pathways, highlighting the need for updates. Improved understanding of aerosol transmission through studies of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection calls for a reassessment of major transmission pathways for other respiratory viruses, enabling better control measures to reduce airborne transmission.

Evaluating the presence of SARS-CoV-2 RNA in the particulate matters during the peak of COVID-19 in Padua, northern Italy

A. Pivato et al.

Summary: The airborne transmission of SARS-CoV-2 is hypothesized as a primary route of transmission, with higher probability in closed environments. Some Italian cities showed a correlation between PM10 concentration exceeding limits and COVID-19 prevalence. However, a study in Northeastern Italy found no presence of SARS-CoV-2 RNA in outdoor PM samples, confirming the low probability of virus transmission through PM.
