Antimony‐based chalcogenides have emerged as promising candidates for next‐generation thin film photovoltaics. Particularly, binary Sb2S3 thin films have exhibited great potential for optoelectronic applications, due to the facile and low‐cost fabrication, simple composition, decent charge transport and superior stability. However, most of the reported efficient Sb2S3 solar cells are realized based...
Hypoxia has been shown to induce gemcitabine (GEM) resistance in pancreatic ductal adenocarcinoma (PDAC) cells, however, the underlying mechanisms remain to be clarified. In the present study, we investigated whether activation of Vav1/Rac1/HIF‐1α axis is responsible for hypoxia‐induced GEM resistance in PDAC cells. Our results showed that Rac1 activation contributed to hypoxia‐induced GEM resistance...
