We describe design and characterization of an aerosol NanoSpot™ collector, designed for collection of airborne particles on a microscopy substrate for direct electron and optical microscopy, and laser spectroscopy analysis. The collector i...
Transmission of SARS-CoV-2 in the workplace: Key findings from a rapid review of the literature [0.03%]
工作场所新型冠状病毒肺炎传播的文献综述之关键发现
Jennie Cox,Brian Christensen,Nancy Burton et al.
Jennie Cox et al.
At the beginning of the COVID-19 pandemic, the primary route of transmission of the SARS-CoV-2 virus was not well understood. Research gathered from other respiratory infectious diseases, including other coronaviruses, was the basis for the...
Constant vs. cyclic flow when testing face masks and respirators as source control devices for simulated respiratory aerosols [0.03%]
恒定气流与周期性呼吸气流下测试面部口罩和呼吸器作为模拟呼吸道气溶胶来源控制装置的效果

This article introduces REAS (Rutgers Electrostatic Active Sampler), a new active bioaerosol sampler using permanently polarized ferroelectric film (e.g., PVDF) to capture charge-carrying bioaerosol particles. While REAS operates on an elec...
Toxic emissions resulting from sucralose added to electronic cigarette liquids [0.03%]
电子烟液中添加蔗糖醇产生的有毒排放物
Rachel El-Hage,Ahmad El-Hellani,Christina Haddad et al.
Rachel El-Hage et al.
Electronic cigarettes (ECIGs) are appealing in part because of the many flavors of the liquids used in them. Concerns have been raised that some ECIG liquid flavors, especially those that are sweet, are attracting otherwise nicotine-naïve ...
Efficacy of Aerosol Reduction Measures for Dental Aerosol Generating Procedures [0.03%]
口腔气溶胶产生操作的气溶胶减少措施的有效性
