Synergetic Interface and Bulk Defects Modification with Identical Organic Molecule for Efficient Inverted Perovskite Solar Cells.

Recent progress in inverted perovskite solar cells (IPSCs) mainly focused on NiO modification and perovskite (PVK) regulation to enhance efficiency and stability. However, most works address only monofunctional modifications, and identical molecules with the ability to simultaneously optimize NiO interface and perovskite bulk phase have been rarely reported. This work proposes a dual modification approach using 4-amino-3,5-dichlorobenzotrifluoride (DCTM) to optimize both NiO upper interfaces and reduction of bulk defects in perovskite.

Autophagy Modulates Glioblastoma Cell Sensitivity to Selinexor-mediated XPO1 inhibition.

Background: Selinexor is a selective inhibitor of exportin-1 (XPO1), a key mediator of the nucleocytoplasmic transport for molecules critical to tumor cell survival. Selinexor's lethality is generally associated with the induction of apoptosis, and in some cases, with autophagy-induced apoptosis. We performed this study to determine Selinexor's action in glioblastoma (GBM) cells, which are notoriously resistant to apoptosis.
