[en] The outbreak of pneumonia caused by novel coronavirus (SARS-CoV-2) in Wuhan, China, at the end of 2019 quickly escalated into a global health emergency. Since its outbreak until the 29th of April 2020, the pandemic has affected more than 3 million of people and caused 207,973 deaths globally. SARS-CoV-2 belongs to the β-coronavirus genus of the Coronavirus family, and it shares the same subfamily with severe acute respiratory syndrome-associated coronavirus (SARS-CoV) and Middle East respiratory syndrome-associated coronavirus (MERS-CoV), all of which lead to severe pneumonia. For cancer patients, especially those with lung cancers, their immune systems are compromised due to the disease itself as well as the treatment for cancer. The weakened immunity of these patients puts them at a higher risk of not only developing diseases but severe diseases. In this study, through a literature review and data collection, we focus on the selection and consideration of antitumor treatment strategies for advanced lung cancer during the coronavirus disease 2019 (COVID-19) epidemic.

[en] Highlights: • New organic superlattices with large Seebeck coefficient and low thermal conductivity, comparable to MOFs. • Methodology of obtaining high electrical conductivity without significantly increasing thermal conductivity. • Extensive experimental studies to unveil the origin of mixed carrier in composites, promising for single-material devices. Solar energy conversion is of great interest in developing green and sustainable energy. Herein, we report the solar-to-electricity capability of a new two dimensional (2D) Cu₂S-phenol superlattice (CP-SL) and carbon nanotubes (CNTs) composites for the first time. CP-SL is demonstrated to have a high Seebeck coefficient and a low thermal conductivity comparable to that of metal-organic frameworks. CP-SL based solar thermoelectric generator (STEG) exhibits stable output voltages for long time usages superior to previously reported STEGs. The device is made of p- and n-type modules that are composed of CP-SL/CNT and CP-SL/polyethyleneimine (PEI) doped CNTs (PEI-CNT) composites, respectively. The polarity of the composites is dominated by the CNTs which have higher carrier concentration. The carrier transport mechanism in the composites matches well with a parallel model, indicating the CP-SL and CNT interfaces play a minor role in carrier transport. The maximum ZT value of CP-SL/CNT is achieved by an in-situ growth method, which is about 35 times higher than that of the original CP-SL. These results indicate that 2D CP-SL is a new material with tunable thermoelectric properties and polarities, which may lay a foundation to realize p- and n-type properties in one material for single-material organic electronic devices development.
