Abstract Background and aims Sorghum ( bicolor ) is able to exude allelochemicals with biological nitrification inhibition (BNI) capacity. Therefore, sorghum might be an option as cover crop since its BNI ability may reduce N pollution in the following due a decreased nitrification. However, exudation related physiological state development of plant, so abiotic stresses such drought modify rate...

Abstract The exploitation of the optimal optical properties lead halide perovskite nanocrystals in optoelectronic devices is mainly hindered by low stability such materials. Here, a molten‐salts approach developed to encapsulate CsPbBr 3 (together with KNO , NaNO and KBr inorganic salts) inside different nanoscale mesoporous SiO 2 host matrices, having sizes between 100 300 nm. comparison produ...

Abstract Maintenance of root elongation is beneficial for the growth and survival plants under salt stress, but currently cellular components involved in regulation high salinity are not fully understood. In this study, we identified an Arabidopsis mutant, rres1 , which exhibited reduced treatment a variety salts, including NaCl, NaNO 3 KCl, KNO . RRES1 encodes novel mitochondrial protein its m...

Abstract Hybrid chemical vapor deposition (HCVD) is a promising method for the up‐scalable fabrication of perovskite solar cells/modules (PSCs/PSMs). However, efficiency HCVD‐based cells still lags behind solution‐processed PSCs/PSMs. In this work, oxygen loss electron transport layer SnO 2 in HCVD process and its negative impact on cell device performance are revealed. As counter‐measure, pota...
