Domed‐rim microbial polygons and their preservation potential
The Depositional Record, Volume 12, Issue 1, February 2026.Microbially induced sedimentary structures (MISS) derive through interactions between minerals and microorganisms. We define a domed‐rim MISS, morphologically distinct from abiotic mud cracks and demonstrate its potential for long‐term preservation. These structures represent promising biosignatures in ancient environments on Earth and potentially Mars.

Effect of Solution Composition on the Passivation of Anode in Copper Electrorefining
Journal of MMIJ, 2017 To elucidate the effect of solution composition on the passivation of anode in Cu electrorefining, the potentiodynamic polarization curves were measured by polarizing from -0.2 V versus NHE to 1.0 V using the potential sweep method at 1.0 mV·s−1.

IET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.This study proposes a novel dual fitness–distance balance chaotic evolution optimisation (DFDBCEO) algorithm for the highly accurate parameter estimation of proton exchange membrane fuel cell models. By integrating global spatial distance and local neighbourhood diversity, the proposed architecture effectively prevents premature convergence in complex ...

Processing of anode slime with deep eutectic solvents as a green leachant
Hydrometallurgy, 2021 Abstract This paper describes an efficient process of recovering valuable metals from a copper anode slime sample using green chemicals such as choline chloride (ChCl) based deep eutectic solvents (DESs). The leaching agents include ChCl-urea, ChCl-ethylene glycol, ChCl-urea-ethylene glycol and ChCl/urea-deionized water in a 1:2, 1:2, 1:0.5:1.5, and ...
