The improvement was significantly higher for catalyst with lower initial activity. However, the materials showed a disappointing catalytic stability during alkaline electrochemical OER, while the crystal structure was found to be stable at working conditions. © 2020 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.To design high-performance mid-infrared (IR) nonlinear optical (NLO) materials, we have focused on the combination of a heavy metal lone pair cation, Pb 2+ and mixed oxyhalides. A systematic investigation in PbO-PbCl 2 -PbBr 2 system led us to discover the first examples of NLO lead mixed oxyhalides, namely, Pb 13 O 6 Cl 4 Br 10 , Pb 13 O 6 Cl 7 Br 7 , and Pb 13 O 6 Cl 9 Br 5 . All the reported materials have remarkably comprehensive properties including broad IR transparency (up to 14.0 μ m), qualified second harmonic generation (SHG) responses (0.6-0.9 × AgGaS 2 ), wide bandgaps (3.05-3.21 eV), and ease of crystal growth. Interestingly, a centimeter-sized single crystal (2.9 × 1.3 × 0.5 cm 3 ) of Pb 13 O 6 Cl 9 Br 5 revealing a wide transparent range (0.384-14.0 μ m) and high laser damage threshold (LDT) (14.6 × AgGaS 2 ) has been successfully grown in an open system. The study suggests that all the reported mixed oxyhalides are outstanding candidates for mid-IR NLO materials. © 2020 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.Esophageal squamous cell carcinoma (ESCC) belongs to one of the most common malignant tumors worldwide and possesses high mortality. Long non-coding RNAs (lncRNAs) have been demonstrated to be essential biological participants in the progression of ESCC. Based on bio-informatics prediction, forkhead box P4 antisense RNA 1 (FOXP4-AS1) and forkhead box P4 (FOXP4) were upregulated in esophageal carcinoma samples and were positively correlate
