TL;DR: Dong et al. as discussed by the authors proposed an interpenetrating perovskite at the electron-transporting layer interface that enables a 1000-hour stable operation and high endurance against bending fatigue over 2500 cycles.
Abstract: The perovskite solar cell has emerged rapidly in the field of photovoltaics as it combines the merits of low cost, high efficiency, and excellent mechanical flexibility for versatile applications However, there are significant concerns regarding its operational stability and mechanical robustness Most of the previously reported approaches to address these concerns entail separate engineering of perovskite and charge-transporting layers Herein we present a holistic design of perovskite and charge-transporting layers by synthesizing an interpenetrating perovskite/electron-transporting-layer interface This interface is reaction-formed between a tin dioxide layer containing excess organic halide and a perovskite layer containing excess lead halide Perovskite solar cells with such interfaces deliver efficiencies up to 222% and 201% for rigid and flexible versions, respectively Long-term (1000 h) operational stability is demonstrated and the flexible devices show high endurance against mechanical-bending (2500 cycles) fatigue Mechanistic insights into the relationship between the interpenetrating interface structure and performance enhancement are provided based on comprehensive, advanced, microscopic characterizations This study highlights interface integrity as an important factor for designing efficient, operationally-stable, and mechanically-robust solar cells Operational stability and mechanical robustness remain as engineering bottlenecks in perovskite solar cells technology Here, Dong et al introduce an interpenetrating perovskite at the electron-transporting-layer interface that enables a 1000-hour stable operation and high endurance against bending fatigue over 2500 cycles

TL;DR: A model on the interrelationships among the reading-related skills and Chinese reading at both word and text levels was proposed and suggested that orthographic skills and morphological awareness each contributed significant amount of unique variance to Chinese word reading and spelling.
Abstract: The contributions of six important reading-related skills (phonological awareness, rapid naming, orthographic skills, morphological awareness, listening comprehension, and syntactic skills) to Chinese word and text reading were examined among 290 Chinese first graders in Hong Kong. Rapid naming, but not phonological awareness, was a significant predictor of Chinese word reading and writing to dictation (i.e., spelling) in the context of orthographic skills and morphological awareness. Commonality analyses suggested that orthographic skills and morphological awareness each contributed significant amount of unique variance to Chinese word reading and spelling. Syntactic skills accounted for significant amount of unique variance in reading comprehension at both sentence and passage levels after controlling for the effects of word reading and the other skills, but listening comprehension did not. A model on the interrelationships among the reading-related skills and Chinese reading at both word and text level...

TL;DR: Zhang et al. as mentioned in this paper investigated the physicochemical properties and natural colonization of plants on five lead/zinc (Pb/Zn) mine tailings in southern China, including Fankou and Lechang in Guangdong Province, and Huangshaping, Shuikoushan, and Taolin in Hunan Province.
Abstract: Mine tailings can have a specific assemblage of plant species due to their unique physicochemical properties, and this process can be important in developing ecological theory and restoration practice. Physicochemical properties and natural colonization of plants on five lead/zinc (Pb/Zn) mine tailings in southern China were investigated. The tailings studied included Fankou and Lechang in Guangdong Province, and Huangshaping, Shuikoushan, and Taolin in Hunan Province. Physicochemical properties of the tailings varied greatly both among and within tailings ponds, but in general, all contained high concentrations of heavy metals (Pb, Zn, Cu, and Cd) and low concentrations of N, P, and organic matter. Toxic levels of heavy metals and deficiency of major nutrients appeared to be the major constraints for colonization of plants on these Pb/Zn tailings and were reflected in the metal concentration of the plant tissues. The natural colonization of plants on these tailings was limited, with only some small patches distributed mainly on the edge of tailing ponds and even fewer patches on the center of the ponds. In total 54 plant species belonging to 51 genera and 24 families were recorded on the five tailings ponds, of which the 13 species belonging to Gramineae were major components of the tailings’ flora. Species establishing on the tailings at the initial colonization phase greatly depended on their seed-dispersal capacity. Further establishment and growth were then dependent on at least one of the three ecological strategies: (1) microsite (avoidance) strategy: plant establishment on tailings depended on dispersing onto microsites of relatively favorable edaphic conditions; (2) tolerance strategy: plant establishment was a result of evolving metal-tolerant ecotypes or constitutional metal tolerance; and (3) rhizome strategy: plant establishment on tailings depended on clonal growth by rhizomatous extension.
