Modulating the properties of g-C3N4 through two-step annealing and ionic-liquid gating.

We reported a novel strategy by the combination of two-step annealing treatment and ionic-liquid gating technology for effectively regulating the properties of g-C3N4, especially largely reducing the recombination rate of the electron-hole pairs, with evidenced by the remarkable reduction of photoluminescence (PL) intensity. Firstly, graphitic carbon nitrides with typical layered structure were obtained by annealing melamine with temperature above 500°C. Further annealing at 600°C with much longer time (from 2 hours to 12 hours) were found to effectively reduce the imperfections or defects, and thus the PL intensity (49% reduction).

Stable Cycling of All-Solid-State Lithium Batteries Enabled by Cyano-Molecular Diamond Improved Polymer Electrolytes.

The interfacial instability of the poly(ethylene oxide) (PEO)-based electrolytes impedes the long-term cycling and further application of all-solid-state lithium metal batteries. In this work, we have shown an effective additive 1-adamantanecarbonitrile, which contributes to the excellent performance of the poly(ethylene oxide)-based electrolytes. Owing to the strong interaction of the 1-Adamantanecarbonitrile to the polymer matrix and anions, the coordination of the Li-EO is weakened, and the binding effect of anions is strengthened, thereby improving the Li conductivity and the electrochemical stability.

DOS-3 mediates cell-non-autonomous DAF-16/FOXO activity in antagonizing age-related loss of C. elegans germline stem/progenitor cells.

Age-related depletion of stem cells causes tissue degeneration and failure to tissue regeneration, driving aging at the organismal level. Previously we reported a cell-non-autonomous DAF-16/FOXO activity in antagonizing the age-related loss of germline stem/progenitor cells (GSPCs) in C. elegans, indicating that regulation of stem cell aging occurs at the organ system level.

NaV(PO)-decorated NaV(PO)F as a high-rate and cycle-stable cathode material for sodium ion batteries.

Since NaV(PO) (NVP) possesses modest volume deformation and three-dimensional ion diffusion channels, it is a potential sodium-ion battery cathode material that has been extensively researched. Nonetheless, NVP still endures the consequences of poor electronic conductivity and low voltage platforms, which need to be further improved. On this basis, a high voltage platform NaV(PO)F was introduced to form a composite with NVP to increase the energy density.

Structurally diverse cucurbitane-type triterpenoids from the tubers of Hemsleya chinensis with cytotoxic activity.

Ten previously undescribed cucurbitane-type triterpenoids, namely hemslyencins A-F (1-6) and hemslyencosides A-D (7-10), together with twenty previously reported compounds (11-30), were isolated from the tubers of Hemsleya chinensis.
