An Effective Local Search for Hybrid Flow Shop Scheduling Problems [PDF]

Proceedings of the 2015 4th International Conference on Sensors, Measurement and Intelligent Materials, 2016
To solve the hybrid flow shop scheduling problems with minimum makespan objective, a local search based on the active scheduling technique was proposed. First, a good initial solution was generated by the NEH-based heuristic. Next, a problem-specif ic local search was developed to improve the initial solution.

MnI‐Functionalized Covalent Organic Framework as Efficient Electrocatalyst for CO2 Reduction in a Catholyte‐Free Zero‐Gap Electrolyzer

Advanced Functional Materials, EarlyView.
This work demonstrates the successful integration of a phenanthroline‐based 2D COF with MnI catalytic sites into a catholyte‐free membrane‐electrode‐assembly cell for CO2 electroreduction. The crystalline COF actively suppresses Mn⁰–Mn⁰ dimerization, achieving a turnover frequency of 617 h⁻¹ at 2.8 V (full‐cell potential), and enabling stable operation.
