Disulfide Bonds Reinforced Self-Assembly of Cellulosic Wastes Toward N/S-Enriched 3D Carbon Foams with Starfish-Like Networks for High-Performance Supercapacitors.

Developing high-performance electrodes derived from cellulosic wastes is an effective strategy for promoting large-scale energy storage and achieving carbon neutrality, yet how to enhance capacitive activity from the perspective of surface-interface structure regulation remains a challenge. Herein, a disulfide bond reinforced self-assembly of cellulosic wastes strategy is demostrated to fabricate 3D carbon foams with thiram and bio-straws as examples. The cellulose-enriched piths of straws (EP) are impregnated with thiram solution followed by pyrolysis, where thiram can form a stable 3D cross-linked networks via disulfide-centered hydrogen bonds reinforced self-assembly of EP and thiram, endowing the obtained starfish-like skeleton connected 3D carbon foams with high N/S contents and hierarchical porous structure.

Output-Only Time-Varying Modal Parameter Identification Method Based on the TARMAX Model for the Milling of a Thin-Walled Workpiece.

The process parameters chosen for high-performance machining in the milling of a thin-walled workpiece are determined by a stability prediction model, which needs accurate modal parameters of the machining system. However, the in-process modal parameters are different from the offline modal parameters and are difficult to precisely obtain due to material removal. To address this problem, an accurate time-dependent autoregressive moving average with an exogenous input (TARMAX) method is proposed for the identification of the modal parameters in the milling of a thin-walled workpiece.
