Laser‐Textured Field‐Engineered Interface for Robust Dry‐Processed Cathodes in Lithium‐Ion Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Laser‐patterned dry electrodes applied to current collectors could serve as a promising alternative to the limitations of conventional dry electrodes. Laser technology provides a fast and simple method to enhance the surface roughness of current collectors, improving the adhesion at the electrode–current collector interface.

Carbon Nanopatch‐Decorated Defect‐Rich Regions for Stable Zinc Metal Anodes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
To improve the stability of Zn anodes, a carbon‐nanopatch strategy based on candle‐flame pyrolysis is proposed. After rinsing, carbon nanoparticles are mainly retained in defect‐rich regions on the Zn surface, where they help alleviate local field intensification, improve interfacial uniformity, and mitigate parasitic reactions.

The Serendipitous Discovery of Rollover Cyclometalation: From Unrecognized Observation to Transformative Chemistry

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Rollover cyclometalation is a distinctive variant of classical cyclometalation where a chelated heterocyclic ligand undergoes internal rotation, releasing one donor atom from coordination and subsequently activating a remote C─H bond with high regioselectivity.

A Rolling Simulation System for Reversing Rolling Mills

open access: yesMATEC Web of Conferences, 2018
In this work a rolling simulation system has been developed for rolling schedules which consists of multiple reversing rolling mills. A slice model approach is applied where the position of a slice can only be determined by considering total deformation.
