Abstract

Three hydroxyl functionalized crystalline K‐doped g‐C3N4 were synthesized from dicyandiamide, melamine, ammonium chloride, ammonium oxalate, and ammonium citrate via ionothermal polycondensation using KCl as molten salt under N2 atmosphere, which served as efficient recyclable photocatalysis realized that generating H2O2 directly from seawater with air by 2e− ORR pathway under stimulated solar irradiation in ambient conditions. Under optimized conditions, the highest H2O2 production rate of 1622 μmol g−1 h−1 for duration of 10 h was obtained. The cycling performances of HPCN‐2 displayed reusable for five times without noticeably loss of its catalytic activity. This work presents a real safer, sustainable, and economical approach for production of H2O2 directly from abundant natural seawater. [ABSTRACT FROM AUTHOR]

Abstract

Lithium sulfide is the baric raw material for the synthesis of sulfur based solid electrolyte. Lithium sulfide was prepared by carbonization reduction method with lithium sulfate as raw material and sucrose as carbon source. The thermodynamic calculation and analysis of the pyrolysis reaction of lithium sulfate and carbon were carried out. The effects of reluctant type, carnation temperature and carnation time on the content of Li2 S in the product were investigated. The results show that the main reaction for the formation of lithium sulfide occurs when the calcination temperature is higher than 660 °C, and 700 °C, and there will be side reactions for the formation of Li2O and Li2CO3. Using sucrose as reducing agent, carbonization coating was carried out under argon protection, followed by high- temperature calcination and reduction. Lithium sulfide with Li2S content of more than 99% could be obtained by reacting at 675 C for 9 h and 775 C for 1. 5 h. In the actual production process, the control of temperature and time is a benefit balance point. [ABSTRACT FROM AUTHOR]

Abstract

Key message: The transcriptome profiling in replanting roots revealed that expression pattern changes of key genes promoted important metabolism pathways, antioxidant and pathogen defense systems, adjusted phytohormone signaling and inhibited lignin biosynthesis.Abstract: The yield of the medicinal plant Achyranthes bidentata could be significantly increased when replanted into a field cultivated previously for the same crop, but the biological basis of this so-called “replanting benefit” is unknown. Here, the RNA-seq technique was used to identify candidate genes responsible for the benefit. The analysis of RNA-seq libraries prepared from mRNA extracted from the roots of first year planting (normal growth, NG) and second year replanting (consecutive monoculture, CM) yielded about 40.22 GB sequencing data. After de novo assembly, 87,256 unigenes were generated with an average length of 1060 bp. Among these unigenes, 55,604 were annotated with public databases, and 52,346 encoding sequences and 2881 transcription factors were identified. A contrast between the NG and CM libraries resulted in a set of 3899 differentially transcribed genes (DTGs). The DTGs related to the replanting benefit and their expression profiles were further analyzed by bioinformatics and qRT-PCR approaches. The major differences between the NG and CM transcriptomes included genes encoding products involved in glycolysis/gluconeogenesis, glutathione metabolism and antioxidant defense, in aspects of the plant/pathogen interaction, phytohormone signaling and phenylpropanoid biosynthesis. The indication was that replanting material enjoyed a stronger level of defense systems, a balance regulation of hormone signals and a suppression of lignin formation, thereby promoting root growth and development. The study provides considerable significant insights for a better understanding of the molecular mechanism of the replanting benefit and suggests their possible application in developing methods to reinforce the effects in medicinal plants.
