A new polymer donor (PBDB-T-SF) and a new small molecule acceptor (IT-4F) for fullerene-free
organic solar cells (OSCs) were designed and synthesized. The influences of …

To simultaneously achieve low photon energy loss (E loss ) and broad spectral response,
the molecular design of the wide band gap (WBG) donor polymer with a deep HOMO level is …

Continuously emerging highly pathogenic human coronaviruses (HCoVs) remain a major
threat to human health, as illustrated in past SARS-CoV and MERS-CoV outbreaks. The …

Background Coronavirus disease 2019 (COVID-19) has evolved into a worldwide pandemic,
and has been found to be closely associated with mental and neurological disorders. We …

Background This is the first randomised controlled trial for assessment of the immunogenicity
and safety of a candidate non-replicating adenovirus type-5 (Ad5)-vectored COVID-19 …

A fast yeast-transformation technique has been developed by adding thio compounds to
alkali-ion based protocols and incubating at 45C. This procedure is especially recommended …

The indispensable requirement for sustainable development of human society has forced
almost all countries to seek highly efficient and cost‐effective ways to harvest and convert solar …

Fabricating organic solar cells (OSCs) with a tandem structure has been considered an effective
method to overcome the limited light absorption spectra of organic photovoltaic materials…

A novel non-fullerene acceptor, possessing a very low bandgap of 1.34 eV and a high-lying
lowest unoccupied molecular orbital level of-3.95 eV, is designed and synthesized by …

The targeting range of CRISPR–Cas9 base editors (BEs) is limited by their G/C-rich
protospacer-adjacent motif (PAM) sequences. To overcome this limitation, we developed a CRISPR–…
