Synergistic Interfacial Optimization for High-Sulfur-Content All-Solid-State Lithium-Sulfur Batteries.

Improving the sulfur content in the cathode is essential for achieving high-energy-density all-solid-state lithium-sulfur batteries (ASSLSBs). However, the complex multiinterfaces, akin to the short wooden planks that consist of the cask, severely limit the performance of ASSLSBs with high sulfur content. Since singular approaches fail to optimize these interfaces simultaneously, we propose a synergistic approach using a dual-doped sulfide solid electrolyte (YS and LiI) and an SbSn alloy sulfur host in this work.

High-Efficiency Hybrid Sulfur Cathode Based on Electroactive Niobium Tungsten Oxide and Conductive Carbon Nanotubes for All-Solid-State Lithium-Sulfur Batteries.

All-solid-state lithium-sulfur batteries (ASSLSBs) have become a promising candidate because of their high energy density and safety. To ensure the high utilization and electrochemical capacity of sulfur in all-solid-state batteries, both the electronic and ionic conductivities of the sulfur cathode should be as high as possible. In this work, an intercalation-conversion hybrid cathode is proposed by distributing sulfur evenly on electroactive niobium tungsten oxide (NbWO) and conductive carbon nanotubes (CNTs) for achieving high performance ASSLSBs.

Congener Substitution Reinforced LiPSbSO Glass-Ceramic Electrolytes for All-Solid-State Lithium-Sulfur Batteries.

Glass-ceramic sulfide solid electrolytes like LiPS are practicable propellants for safe and high-performance all-solid-state lithium-sulfur batteries (ASSLSBs); however, the stability and conductivity issues remain unsatisfactory. Herein, we propose a congener substitution strategy to optimize LiPS as LiPSbSO via chemical bond and structure regulation. Specifically, LiPSbSO is obtained by a SbO dopant to achieve partial Sb/P and O/S substitution.

[Expression and enzyme activity analysis of Djtry in planarian Dugesia japonica].

The cDNA Djtry, encoding a planarian trypsin, was identified from the cDNA library of Dugesia japonica. Multiple alignment analysis showed that the Tryps_SPc domain contained the incompletely conserved catalytic triad in which the first amino acid His was substituted by Lys. Phylogenetic analysis indicateed that Djtry protein falls at the base of other animal trypsins.

Analyzing S-adenosylhomocysteine hydrolase gene sequences in deuterostome genomes.

S-adenosylhomocysteine hydrolase (SAHH) gene sequences of sea-urchin, two amphioxus, sea-squirt and eight vertebrates are comparatively analyzed in the current analysis. Although SAHH protein sequences are highly conserved in these species, their nucleotide sequences are much different, ranging from 5,446 bp in amphioxus to 40,174 bp in zebra fish. The length divergence is mainly caused by distinct introns in some species.

[Toxic effects of nonylphenol on the gonad of adult rosy barb].

Acute and sub-acute toxicities of nonylphenol (NP) on fish were investigated with adult rosy barb (Puntius conchonius). The acute toxicity of NP to adult rosy barb was determined in semi-static bioassays. Median lethal concentration (LC50) value of NP was (1.
