Efficient One-Step Synthesis of a Pt-Free Zn_0.76Co_0.24S Counter Electrode for Dye-Sensitized Solar Cells and Its Versatile Application in Photoelectrochromic Devices [PDF]

Nanomaterials, 2023
In this study, we synthesized a ternary transition metal sulfide, Zn0.76Co0.24S (ZCS-CE), using a one-step solvothermal method and explored its potential as a Pt-free counter electrode for dye-sensitized solar cells (DSSCs).

Investigating Zcs(3985) and Zcs(4000) exotic states in Λb→Zcs−p decays

Physics Letters B
We study the Zcs(3985) and Zcs(4000) exotic states in the decays of Λb baryons through a molecular scenario. In the final state interaction, the Λb→Λc+Ds(⁎)− decays are followed by the Λc+Ds(⁎)− to Zcs−p rescatterings via exchange of a D(⁎) meson.
