  COVID-19 has shown a high potential of transmission via virus-carrying aerosols as supported by growing evidence. However, detailed investigations that draw direct links between aerosol transport and virus infection are still lacking. To fill in the gap, we conducted a systematic computational fluid dynamics (CFD)-based investigation of indoor airflow and the associated aerosol transport in a restaurant setting, where likely cases of airflow-induced infection of COVID-19 caused by asymptomatic i…

  reviewOpen accessSenior author

  Abstract Advanced three-dimensional (3D) tracking methods are essential for studying particle dynamics across a wide range of complex systems, including multiphase flows, environmental and atmospheric sciences, colloidal science, biological and medical research, and industrial manufacturing processes. This review provides a comprehensive summary of 3D particle tracking and flow diagnostics using digital holography (DH). We begin by introducing the principles of DH, accompanied by a detailed disc…

• Novel Release Mechanism of Microplastics and Nanoplastics by Environmentally Relevant Sand Abrasion

  Environmental Science & Technology · 2025-09-19 · 7 citations

  ). Beyond suspended debris, we discovered that MPs/NPs' (sub- to low-micron) can transfer onto sand grains- a novel and major release mechanism that could serve as a new source of MPs/NPs. Simultaneously, a dynamic layer of sand minerals was deposited on LDPE. Such mutual transfer is hypothesized to be stochastic and to interfere with the subsequent MP/NP release. Our findings highlight that MP/NP release and fate from environmentally relevant sand abrasion are more complex than our previous und…
