Practical Indicators for Risk of Airborne Transmission in Shared Indoor Environments and Their Application to COVID-19 Outbreaks

Peng, Z. (author), Pineda Rojas, A.L. (author), Kropff, E. (author), Bahnfleth, W. (author), Buonanno, G. (author), Dancer, S.J. (author), Kurnitski, J. (author), Li, Y. (author), Boerstra, A.C. (author), Jimenez, J.L. (author)

Some infectious diseases, including COVID-19, can undergo airborne transmission. This may happen at close proximity, but as time indoors increases, infections can occur in shared room air despite distancing. We propose two indicators of infection risk for this situation, that is, relative risk parameter (Hr) and risk parameter (H). They combine...

2D Dion–Jacobson CsPbI₃ with Enhanced Interlayer Coupling for Stable and Efficient Photovoltaics

Lei, Yutian (author), Peng, Guoqiang (author), Wang, H. (author), Wang, Gang (author), Yang, Siwei (author), Wang, Qian (author), Li, Zhen Hua (author), Jin, Zhiwen (author)

Inorganic 2D layered CsPbI₃ is awaiting to overcome the phase instability of traditional 3D components. However, the most reported Ruddlesden–Popper (RP) phase 2D CsPbI₃ leads to larger interlayer distance and weaker interlayer coupling since the existence of the van der Waals gap, which deteriorates the performance of...
