The vertical composition distribution and crystallinity of photoactive layers are considered to have critical roles in photovoltaic performance. In this concise contribution, the layer-by-layer (LBL) solution process is used fabricate efficient polymer solar cells. results show that can be finely regulated via employing solvent additive 1,8-diiodooctane (DIO). favorable component tandem with improved induced by DIO contributes exciton dissociation, charge transportation extraction, limited...
Abstract Amorphous Ga 2 O 3 (a-Ga ) has been attracting more and attention due to its unique merits such as wide bandgap (∼4.9 eV), low growth temperature, large-scale uniformity, cost energy efficient, making it a powerful competitor in flexible deep ultraviolet (UV) photodetection. Although the responsivity of ever-reported a-Ga UV photodetectors (PDs) is usually level hundreds A/W, often accompanied by large dark current presence abundant oxygen vacancy ( V defects, which severely limits...
Abstract The transcriptional factor Forkhead box k1 (FOXK1) is a member of the FOX family. abnormal expression FOXK1 may have an important role in tumour development.

However, molecular mechanism by which synergizes with FHL2 proliferation, EMT metastasis not well defined. We evaluated messenger RNA (mRNA) levels quantitative RT–PCR, western blot,...
The vertical composition distribution of a bulk heterojunction (BHJ) photoactive layer is known to have dramatic effects on photovoltaic performance in polymer solar cells. However, the evolution rules BHJ films are still elusive. In this contribution, three film systems, composed donor PBDB-T, and different classes acceptor (fullerene PCBM, small-molecule ITIC, N2200) systematically investigated using neutron reflectometry examine how donor–acceptor interaction solvent additive impact...
Abstract The bulk morphology of the active layer organic solar cells (OSCs) is known to be crucial device performance. thin film structure breaks symmetry into in-plane direction and out-of-plane with respect substrate, leading an intrinsic anisotropy in morphology. However, characterization nanomorphology within remains a grand challenge. Here, we utilized X-ray scattering technique, Grazing-incident Transmission Small-angle Scattering (GTSAXS), uncover this new dimension. This technique...
We systematically investigated the manipulation of antiferromagnetic interfacial states through current-induced spin-orbit torques (SOT) in $\mathrm{Pt}/\mathrm{Co}/{\mathrm{Ir}}_{25}{\mathrm{Mn}}_{75}(\mathrm{Ir}\text{\ensuremath{-}}\mathrm{Mn})$ system with varying Ir-Mn or Co thickness. The high tunability states, that spins gradually switched from upward to downward vice versa by SOT, was achieved for samples ${t}_{\mathrm{IrMn}}\ensuremath{\ge}4\mathrm{nm}$, whereas switching ability...

In the field of organic solar cells (OSCs), planar heterojunctions (PHJs) have received less attention. This study demonstrates that enhancing crystallization and diffusivity nonfullerene small-molecule acceptors (NF-SMAs) through sequential deposition significantly optimizes morphology PHJ OSCs, driving notable performance enhancements. An additive 1,2,4,5-tetrabromobenzene (TBrB) is employed during deposition, enabling such desirable morphological control in OSCs. situ UV-vis absorption...
Abstract The formation of dendrites associated with corrosion reactions undermines the cycling stability aqueous zinc‐ion batteries (AZBs). Despite extensive efforts, conventional strategies, e.g., electrolyte modification, and artificial protection layers, often suffer from low stability. Inspired by cell membranes, a series phospholipid analogues C n P m is designed which can spontaneously adsorb onto Zn electrode to form bimolecular protective layer. By tuning head length or tail lipid...
Because of their potent regenerative and immunomodulatory properties, mesenchymal stem cells (MSCs) have promising therapeutic benefits in clinical treatment inflammatory infectious diseases. Recent studies suggest that many biological activities MSCs are largely determined by pattern recognition receptors (PRRs), such as Toll-like (TLRs). However, the role PRRs regulating survival remains unknown. In present study, we examined viability after stimulation distinct PRRs. Activation TLRs...
