Article Synopsis
- Introducing topological defects in nanographene crystal engineering is key for tuning electronic structures and controlling molecular assemblies, but achieving this in 2D crystals on surfaces presents challenges.
- The study successfully incorporated ladder bipyrazinylene (LBPy) into acene to create nonbenzenoid heteroacene crystals on gold surfaces through a specific chemical process that involves electrocyclization and cycloaddition.
- Advanced techniques like bond-resolved scanning tunneling microscopy and density functional theory (DFT) helped identify the structures and electronic properties of the produced heteroacene, revealing a complex formation process involving various intermediates.
In recent years, immunotherapy strategies based on immune checkpoint inhibitors have yielded good efficacy in colorectal cancer (CRC)especially in colorectal cancer with microsatellite instability-high. However, microsatellite-stable (MSS) CRCs account for about 85% of CRCs and are resistant to immunotherapy. Previous studies have shown that compared with MSS CRC, high microsatellite instability CRC possesses a higher frequency of mutations and can generate more neoantigens.

As diffusive gradients in thin films (DGT) can be used to assess the bioavailability of inorganic matters, in this paper, we evaluated, for the first time, the ecotoxicology risks of REEs and their mixtures in river sediments of China's old industrial base by DGT. During our research, taking the Songhua River system (SRS) as an example, we detected its surficial sediments, of which the DGT-labile concentration of REEs (∑REEs) was 2.

- COVID-19, caused by the SARS-CoV-2 virus, has been rapidly spreading since late 2019, following earlier outbreaks of SARS and MERS.
- The article discusses the origins and virological features of SARS-CoV-2, along with an overview of its global epidemiology.
- It also reviews potential treatments and preventative measures for COVID-19, offering new insights into managing the virus.
