Ultimately, 1D (ZIF-67 derivatives)@(porous carbon nanofiber) were acquired by thermal field modulation. It suggests that, with the increase of annealing temperature, graphitization degree rises, enhancing conductive loss. Meanwhile, more divalent cobalt is reduced, leading to a rise in polarization loss and the effective modulation of magnetic properties. Besides, the rise in porogen addition is accompanied by a decrease in pore volume and an increase in pore size, enhancing electrical conductivity while increasing the number of defects, thus enhancing dielectric loss. Notably, when annealing temperature is 700 °C and porogen addition is 29 wt%, obtained material exhibits excellent reflection loss (−52.49 dB at 1.53 mm) and broad bandwidth (5.29 GHz at 1.62 mm).

The excited-state dynamics of an organic molecules can be sensitively tuned, where even marginal variations in crystal morphology and molecular arrangement can drastically modify their optical behavior.

Unfortunately, the practical applications of Li-metal batteries (LMBs) are impeded by low coulombic efficiency and dendritic Li formation during the charging/discharging process. One of viable strategies for overcoming these challenges involves the use of N-rich carbons in designing functional separators and current collectors. In this study, the potential of organic crystal material (Pigment Red 122; PR122) as a carbonizable nitrogen-rich material was investigated to assess its impacts on the electrochemical performance of Li-ion batteries (LIBs) and LMBs. The carbonization temperature of PR122 was precisely controlled to alter the overall content of nitrogen element in the carbon backbone. Each prepared N-rich carbon was applied to modify the surface of each separator and current collector. The PR122-derived carbon pyrolyzed at a high temperature of 1500 °C (PR|C1500) demonstrated lower discharge capacity. However, it exhibited better electrochemical kinetics than the PR122-derived carbon pyrolyzed at a lower temperature of 600 °C (PR|C600) in LIBs. In the case of LMBs, the Li/Cu cell with a PR|C600 coated separator delivered better cycle stability than the Li/Cu cell with a PR|C1500 coated separator.
