Chitin‐Derived Carbon‐Metal Functional Materials

open access: yesAdvanced Functional Materials, EarlyView.
Functional carbon materials are synthesized from combination of biopolymer (chitin) and iron precursors. The resultant material exhibits superior surface area and adsorptive properties compared to carbon materials synthesized directly from pure chitin.

Recycling Process of Copper and Cobalt Waste Rock in the Democratic Republic of the Congo

open access: yesKuangchan zonghe liyong
The copper grade of the waste rock in the Sicomines copper-cobalt mining area in Congo (DRC) is 1.01%, and the cobalt grade is 0.045%, which has the recycling value. However, the waste rock has problems of high oxidation rate and severe mudding.

Cellular Responses to Mechanical Cues Across Scales: From Fundamental Insights to Translational Potential

open access: yesAdvanced Healthcare Materials, EarlyView.
This review examines how cellular behavior is regulated by mechanical cues transmitted through soft biomaterials, from single‐cell mechanosensing to tissue‐level adaptation. It highlights why physiological relevance, rather than model complexity alone, is critical for translational mechanobiology and introduces a scoring framework linking material ...
