Rechargeable aqueous zinc ion batteries (AZIBs) are attracting extensive attention owing to environmental friendliness and high safety. However, its practical applications are limited to the poor Coulombic efficiency and stability of a Zn anode. Herein, we demonstrate a periodically stacked CuS-CTAB superlattice, as a competitive conversion-type anode for AZIBs with greatly improved specific capacity, rate performance, and stability. The CuS layers react with Zn2+ to endow high capacity, while CTAB layers serve to stabilize the structure and facilitate Zn2+ diffusion kinetics. Accordingly, CuS-CTAB shows superior rate performance (225.3 mA h g–1 at 0.1 A g–1 with 144.4 mA h g–1 at 10 A g–1) and a respectable cyclability of 87.6% capacity retention over 3400 cycles at 10 A g–1. In view of the outstanding electrochemical properties, full batteries constructed with a CuS-CTAB anode and cathode (Zn x FeCo­(CN)6 and Zn x MnO2) are evaluated in coin cells, which demonstrate impressive full-battery performance.

Abscisic acid (ABA) is an endogenous phytohormone that plays important roles in the regulation of plant growth, development, and stress responses. The pyrabactin resistance 1-like (PYR/PYL) protein is a core regulatory component of ABA signaling networks in plants. However, no details regarding this family in Brassica napus are available. Here, 46 PYLs were identified in the B. napus genome. Based on phylogenetic analysis, BnPYR1 and BnPYL1-3 belong to subfamily I, BnPYL7-10 belong to subfamily II, and BnPYL4-6 and BnPYL11-13 belong to subfamily III. Analysis of BnPYL conserved motifs showed that every subfamily contained four common motifs. By predicting cis-elements in the promoters, we found that all BnPYL members contained hormone- and stress-related elements and that expression levels of most BnPYLs were relatively higher in seeds at the germination stage than those in other organs or at other developmental stages. Gene Ontology (GO) enrichment showed that BnPYL genes mainly participate in responses to stimuli. To identify crucial PYLs mediating the response to abiotic stress in B. napus, expression changes in 14 BnPYL genes were determined by quantitative real-time RT-PCR after drought, heat, and salinity treatments, and identified BnPYR1-3, BnPYL1-2, and BnPYL7-2 in respond to abiotic stresses. The findings of this study lay a foundation for further investigations of PYL genes in B. napus.

The aim of this paper is to research the influence of corporate governance structure on internal control disclosure in a sample of 1309 Chinese listed nonfinancial companies in 2010. We discover that internal control disclosure is positively related to directors' remuneration, two part-time posts of chairman and general manager, directors' education level and supervisors' education level, and it negatively related to the proportion of state ownership. Internal control disclosure is not significantly related to the degree of ownership concentration, board size, the proportion of independent directors and the size of board of supervisors.
