Article Synopsis
  • Carbonate-based electrolytes are common in Li-ion batteries because they're safe and stable but struggle with issues in lithium-sulfur batteries due to chemical reactions with polysulfide anions and poor solubility of lithium nitrate.
  • The redesign of solvent molecules reduces the reactivity of carbonyl carbon atoms, enhancing the solubility of lithium nitrate and forming a stable solid electrolyte interface on lithium metal.
  • The modified lithium-sulfur battery demonstrates effective performance with an initial capacity of 1251.7 mAh/g, retains 60% capacity after 420 cycles, and shows stable operation in a symmetrical cell for over 1200 hours.

Lithium metal batteries (LMBs) have become a hot topic in the research of next-generation advanced battery technology due to their high specific energy. However, the high reaction activity between lithium metal and electrolyte is considered one of the key bottlenecks limiting large-scale applications of LMBs. As a classic electrolyte additive, lithium nitrate (LiNO) significantly improves the stability of lithium metal in ether-based electrolytes.

Chronic liver disease or repeated damage to hepatocytes can give rise to hepatic fibrosis. Hepatic fibrosis (HF) is a pathological process of excessive sedimentation of extracellular matrix (ECM) proteins such as collagens, glycoproteins, and proteoglycans (PGs) in the hepatic parenchyma. Changes in the composition of the ECM lead to the stiffness of the matrix that destroys its inherent mechanical homeostasis, and a mechanical homeostasis imbalance activates hepatic stellate cells (HSCs) into myofibroblasts, which can overproliferate and secrete large amounts of ECM proteins.

Article Synopsis
  • Swainonine-producing endophytic fungi are significant poisonous weeds negatively affecting grasslands in the Qinghai-Tibet Plateau, contributing to grassland degradation.
  • * The study involved sequencing the Internally Transcribed Spacer (ITS) region of soil fungal communities to analyze their diversity and relationship with soil physical and chemical properties, finding diversity influenced mainly by soil pH and organic matter.
  • * The detection of swainonine-producing fungi in the root system soil suggests a potential horizontal spread, and a stable core flora network may help this fungus become a dominant species in alpine ecosystems.

Background: Kinesin (KIN) as a motor protein is a versatile nano-machine and involved in diverse essential processes in plant growth and development. However, the kinesin gene family has not been identified in watermelon, a valued and nutritious fruit, and yet their functions have not been characterized. Especially, their involvement in early fruit development, which directly determines the size, shape, yield and quality of the watermelon fruit, remains unclear.
