Summary: Lithium-Sulfur batteries are promising energy storage systems due to their high energy density, environmental friendliness, and low cost. However, the slow redox kinetics of lithium polysulfide (LPS) and its shuttle effect hinder the practical applications of Li-S batteries. This study presents a single atom Fe-N/C catalyst that suppresses the formation of lithium polysulfide and improves the cyclic stability and Coulombic efficiency of lithium-sulfur batteries.

Summary: In this study, the effect of different metal valences in cobalt-based organic framework compounds on the sulfur reaction kinetics in lithium-sulfur batteries was investigated. Two organic framework compounds, Co-ZIF and CoTBP(III), were constructed as functional intercalation separators and their effects on improving the reaction kinetics of polysulfides and inhibiting the shuttle effect were explored. Experiments and theoretical calculations showed that Co-II exhibited the best catalytic activity, attributed to its strong adsorption energy for polysulfides and higher Fermi level compared to Co-III. The Co-ZIF catalytic layer achieved a discharge specific capacity of 772.7 mAhg(-1) at a high current density of 5C, with an attenuation rate of 0.092% per cycle after 720 cycles and coulombic efficiency above 92%.

Two organic framework compounds, Co-ZIF and Co-TBP(III), with different valences were constructed as intercalation separators of LSBs and their effects on improving the reaction kinetics of polysulfides and inhibiting the shuttle effect were explored. Experiments and theoretical calculations showed that Co-II exhibited the best catalytic activity, mainly due to its strong adsorption energy for polysulfides and higher Fermi level compared to Co-III. The discharge specific capacity of Co-ZIF as the catalytic layer of LSBs reached 772.7 mAh g(-1) at a high current density of 5 C, with a cycle attenuation rate of only 0.092% and a coulombic efficiency above 92% after 720 cycles.

Summary: In this study, an isolated Fe-Co heteronuclear diatomic catalyst is reported for high efficiency bifunctional catalysis in lithium-sulfur batteries. The Fe-Co diatomic catalytic materials supported by hollow carbon spheres achieve high-efficiency catalysis for the conversion of polysulfides and the decomposition of Li2S simultaneously. The excellent bifunctional catalytic activity originates from the diatomic synergy between Fe and Co atoms.

Summary: Red soils in subtropical regions are often deficient in available phosphorus, which is essential for plant growth. Phosphate-solubilizing microorganisms (PSMs) can release phosphorus from phosphate reservoirs, but their interactions with minerals in red soils are not fully understood. This study investigated the effects of Aspergillus niger, a phosphate-solubilizing fungus, on phosphorus dissolution in acidic and alkaline red soils. In the acidic soil, A. niger promoted phosphorus release and decreased the content of Fe/Al oxides. In the alkaline soil, phosphorus availability declined after A. niger addition due to the diminished function of PSMs and strong soil buffering.

Summary: In this study, the production of organic acid by Aspergillus niger (A. niger) under different lead (Pb) concentrations was investigated. A. niger showed high Pb tolerance and was able to produce oxalic acid even at 1500 mg/L Pb concentration. The formation of lead oxalate minerals played a key role in protecting A. niger from Pb toxicity. Moreover, the presence of Pb stimulated the activity of pyruvate dehydrogenase enzyme and improved the production of oxalic acid by A. niger.

Summary: Curcumin inhibits the activity and promotes apoptosis of LX-2 cells by suppressing autophagy through activation of the PI3K/Akt/mTOR signaling pathway. In addition, lipid recovery and energy deprivation due to autophagy inhibition may be the mechanism by which curcumin attenuates the pro-fibrotic activity of LX-2.

Summary: Phosphate-solubilizing fungi dissolve insoluble phosphates through organic acid secretion, with Penicillium chrysogenum showing higher efficiency in phosphorus release from tricalcium phosphate than from ferric phosphate. Ferric phosphate significantly increases oxalic acid and citric acid production by Penicillium chrysogenum and induces a transformation of its mycelial morphology from pellet to filamentous. The filamentous morphology exhibits higher efficiency in organic acid secretion and phosphorus release.
