High-performance electromagnetic wave absorption in FeS/SnS@multi-walled carbon nanotube composites with honeycomb-shaped structure.

In this work, we synthesized composites of ferrous disulfide and tin disulfide with multi-walled carbon nanotubes (MWCNTs) using a straightforward hydrothermal method. The incorporation of carbon nanotubes significantly enhanced the dielectric loss capability of the composites. When the filling ratio of FeS/SnS@CNTs (20 wt%) in paraffin was 40%, the effective absorption bandwidth was 3.

Artemisinin attenuated ischemic stroke induced pyroptosis by inhibiting ROS/TXNIP/NLRP3/Caspase-1 signaling pathway.

Background: To explore the neuroprotective mechanism of artemisinin against ischemic stroke from the perspective of NLRP3-mediated pyroptosis.

Methods: Serum metabolomics technology was used to analyze the serum samples of mice, and KEGG metabolic pathway was analyzed for the different metabolites in the samples. PIT model and OGD/R model were used to simulate ischemic stroke damage in vivo and in vitro.

Influence of the physical properties of the layered oxyselenides BiYOCuSe through Ni doping.

We have synthesized a series of Ni-doped layered oxyselenides BiYOCuNiSe (0 ≤ ≤ 0.4). The crystal structure and physical properties were studied through X-ray diffraction, and electric and thermo transport measurements.
