That was namely Ivocerin (di(4-methoxybenzoyl)diethylgermane), ITX (2-iso-propyl thioxanthone), anthracene, pyrene, rubrene, camphore quinone, and a strong fluorescent coumarin (1,1,6,6,8-pentamethyl-2,3,5,6-tetrahyhdro-1H,4H-11-oxa-3a-aza-benzo[de]anthracene-10-one). Quantification occurred by treatment with Rhodamine B lactone whose color switched to intensive red after photolytic formation of con-H+ . Exposure with a NIR laser at 980 nm resulted in less con-H+ compared to 395 nm where all sensitizers absorb radiation. UCNP did not mainly interfered formation of con-H+ . The different rates obtained in both experiments responsibly explain the failure and success to initiate polymerization of epoxides applying ether 980 nm or 395 nm excitation, respectively. To understand COVID patients' experiences of and perspectives on disclosure of their illness and to explore and describe the factors affecting disclosure decisions among COVID patients in China. Disease disclosure is a critical component of prevention and control of a virus outbreak, and this is especially true during the COVID-19 pandemic. Understanding COVID patients' experiences and perspectives on disclosure could play a vital role in COVID management. A qualitative study. A semi-structured interview guide was used to conduct qualitative in-depth interviews from April to June 2020. All the interviews were audio-recorded and transcribed, and then, a thematic analysis was conducted. The Standards for Reporting Qualitative Research (SRQR) were applied to this study. A total of 26 COVID-confirmed patients were recruited for the in-depth interviews. Four themes emerged from the thematic analy
