Wood Carbon Sponge/SiO2 Aerogel Composites with Anisotropic Broadband Microwave Absorption, Elastic Resilience, and Thermal Insulation

Advanced Science, EarlyView.
Anisotropic wood carbon sponge/SiO2 aerogel composites are constructed, revealing a robust direction‐dependent permittivity ordering (tangential > radial > axial). The radial direction delivers an ultra‐broadband effective absorption bandwidth of 11.6 GHz at only 4.95 mm, while the tangential direction offers superior compressibility and thermal ...

A carbon-carbon one-electron bond! Or a weak carbon-carbon interaction?

More than 100 years ago, before the quantum mechanical treatment of molecules had been formulated, G. N. Lewis proposed a simple model for chemical bonding that is still taught today.

Eco‐Friendly Laser‐Induced Graphene/Perovskite Hybrids for Eco‐Friendly Photodetectors

Advanced Electronic Materials, EarlyView.
A sustainable paper‐based photodetector was developed by combining laser‐induced graphene (LIG) with MAPbI3 perovskite. Compared with pure LIG devices, the hybrid photodetector exhibited nearly 10‐fold higher responsivity and 7‐fold greater detectivity while maintaining stable performance after 1000 bending cycles, demonstrating its potential for ...

One‐Step Synthesis of Size‐Controlled Copper Oxide Nanoparticles on Laser‐Induced Graphene Sensor for L‐Cysteine Detection

Advanced Electronic Materials, EarlyView.
Oxygen plasma treatment enhances polyimide hydrophilicity and promotes uniform anchoring of copper ion precursors. A one‐step laser process then generates CuO‐decorated nanoparticles on laser‐induced graphene (LIG) electrodes, enabling controlled nanoparticle growth via precursor concentration tuning.

Multiscale Carbon‐Integrated Silicon Anode for Stable Cycling Under Practical Lithium‐Ion Battery Conditions

Advanced Energy Materials, EarlyView.
To overcome silicon anode instability, a hierarchical silicon/carbon composite fabricated from industrial waste via a scalable milling process is demonstrated. In‐depth post‐mortem analysis reveals how functional carbons—a CNT network and graphene shell—synergistically suppress degradation. This robust design delivers outstanding stability in practical

Caging Polyhalide Anions in Polycyclodextrin for Long‐Lasting Aqueous Zinc‐Iodine Batteries

Angewandte Chemie, EarlyView.
We demonstrated poly(β‐cyclodextrin) gel as an ideal host material that effectively contains and releases polyhalide anions in aqueous zinc‐iodine batteries. Such a unique host‐guest chemistry prevents the shuttle effect of polyhalides. The corresponding batteries can operate via both 2e and 4e storage, attaining 60,000 cycles with more than 99% and 85%

From Materials to Systems: Challenges and Solutions for Fast‐Charge/Discharge Na‐Ion Batteries

Advanced Energy Materials, EarlyView.
This review systematically analyzes the key characteristics limiting the fast‐charge/discharge capability of Na‐ion batteries (SIBs) from a multi‐scale perspective encompassing electrode materials, the electrode‐electrolyte interface, and the system. Furthermore, it presents practical solution strategies for the fundamental issues arising at each scale,
