“…When perovskite films were deposited by the one-step spin-coating method, nucleation occurs right after the drop of an antisolvent and the resulting supersaturation in the residual solution. On the smooth and dense bl-SnO 2 substrate, homogeneous nucleation first occurs on the top zone of the precursor solution induced by the evaporation of the solvent. − During the subsequent crystal growth process, the supersaturation on the top zone was still higher than that on the bottom zone due to the continuous evaporation of the solvent. On the other hand, there are few nucleation sites and low supersaturation on the bottom of the precursor solution .…”

The interfacial contacts between the electron transport layer (ETL) and the perovskite film play a crucial role in high-performance perovskite solar cells (PSCs). Herein, we propose a method for depositing a low-temperature-processed mesoporous TiO 2 (mp-TiO 2 ) layer on the SnO 2 ETL (bl-SnO 2 ) with the flexible substrate to enhance the performance of the PSCs. This kind of mesoporous TiO 2 layer can both improve the interfacial contact without voids in the imbedded interface and enhance the mechanical stability in the interface between TiO 2 and perovskite. The upward growth of perovskite grains on the mesoporous TiO 2 layer leads to a uniform grain size and prevents voids at the ETL/perovskite interface. This excellent interfacial contact is the foundation for the collection and transportation of photogenerated electrons. As a result, the efficient PSCs achieve a power conversion efficiency (PCE) of 19.90% with the additional mp-TiO 2 layer on a flexible substrate. Furthermore, the unencapsulated flexible PSCs show enhanced storage stability and bending durability. This work paves the way for the fabrication of cost-effective and high-quality flexible PSCs with enhanced efficiency and mechanical stability.

Wilms tumor (WT) is the most prevalent urologic malignancy in childhood. Nonetheless, the genetic factors underlying WT remain largely unknown. The miR-423 rs6505162 C>A polymorphism is associated with the susceptibility to numerous cancers; however, no investigations have been conducted on its association with WT. To evaluate the correlation between the miR-423 rs6505162 C>A polymorphism and WT risk in Chinese children, we genotyped this polymorphism using the Taqman method in 145 cases and 531 cancer-free controls. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to estimate the strength of the association. The results showed that the rs6505162 CA genotype was associated with decreased susceptibility to WT (CA versus CC: adjusted OR=0.65, 95% CI=0.42-0.99, P=0.047). In the stratified analysis, we found that CA/AA genotypes conferred a significantly decreased overall risk of WT in children younger than 18 months (adjusted OR=0.30, 95% CI=0.14-0.63, P=0.002) and those with clinical stage I+II WT (adjusted OR=0.42, 95% CI=0.20-0.85, P=0.017) when compared with CC genotype. In summary, the miR-423 rs6505162 C>A polymorphism may negatively modify WT susceptibility in Chinese children. Our findings should be validated in larger studies involving other ethnicities.

SummaryThis study looks at investigating the influence of high surface area TiO 2 and MgO-doped TiO 2 aerogel nanomaterials to improve the photovoltaic performance of monocrystalline silicon (mono-Si) solar cells. TiO 2 and MgO-doped TiO 2 anatase nanoaerogels were synthesized via a single-step colloidal homogeneous precipitation sol-gel method in a compact high-pressure hydrogen reactor. TiO 2 -based nanoparticles were encapsulated in ethylene vinyl acetate resins, and the obtained composite solutions were screen printed on the textured surface of the cells. The specific surface area, microstructural, composition, and optical properties of the nanoaerogels were characterized by Brunaur-Emmett-Teller, X-ray powder diffractometer, energy-dispersive X-ray spectroscopy, field emission transmission electron microscope, field emission scanning electron microscope, and ultraviolet-visible spectrophotometry. We observed that the MgO-doped TiO 2 (2% mol) nanoaerogel exhibited a much superior specific surface area (231 m 2 /g) compared with the undoped TiO 2 (154 m 2 /g). Experimental results showed that the calculated relative power conversion efficiency increased by 4.6% for the MgO-doped TiO 2 coating and 3.4% for the undoped TiO 2 under a simulated one-sun illumination.
