(Nanowerk Spotlight) Hierarchical structures, spanning multiple length scales from nano- to macroscales, are very common in nature; but only in recent years have they been systematically studied in ...

Unfortunately, ZIBs batteries suffer from the insulating iodine, low utilization ratio of active source, and the shuttle effect, resulting in the fast capacity decay and undesirable self-discharging ...

Structural hierarchy is the cornerstone of the biological world, as well as the most important lesson that we have learned from nature to develop ingenious hierarchical porous materials for various ...

The MOF-derived TiO 2 @NPC@S composite has a hierarchical porous structure, which can effectively accommodate sulfur volume expansion and promote ion and electron transport during the charge-discharge ...

Strategically designing heterostructures incorporating highentropy metal particles and carbon fibers can enhance the defect ...

Zn-ion hybrid supercapacitors (ZHSCs) with the integration of a battery-type anode and a capacitor-type cathode have received intense attention due to their relatively high energy density. Porous ...

Researchers have developed a novel method of 3D printing to fabricate 3D porous structures in one step. This method is named as immersion precipitation 3D printing (ip3DP). The porosity of the 3D ...

By converting this hazardous waste into advanced nanoporous carbon electrodes, the researchers demonstrate that cigarette butts can serve as an ...

Recently, iodine has been increasingly used with zinc anodes to fabricate sustainable zinc–iodine (Zn–I 2) batteries (ZIBs) due to its high redox potential (I 2 /I-, 0.62 V vs. standard hydrogen ...
