Biomass‐Derived Laser‐Induced Graphene: From Precursor Chemistry to Device Integration
Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Laser direct writing provides a mask‐free route for converting suitable carbon‐containing precursors into patterned, porous, and conductive laser‐induced graphene (LIG) networks. Although LIG was initially demonstrated mainly using aromatic synthetic polymers, such as polyimide, biomass precursors introduce renewable feedstocks with highly ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Magnetic particles coated with carbon shells have been considered as promising electromagnetic wave absorption materials with antibacterial features. However, how to precisely control the monodispersed magnetic nanoparticles on a carbon matrix to manipulate impedance matching and antibacterial performances is still a key challenge.

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT The immunosuppressive milieu of hepatocellular carcinoma (HCC) remains a major obstacle to durable antitumor responses. Mechanical‐energy‐driven piezocatalysis provides a noninvasive means of inducing oxidative damage and immunogenic tumor destruction; however, inefficient utilization of piezoinduced charges and insufficient localization of ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT High‐yield photocatalytic H2O2 production in sacrificial agent‐free pure water constitutes a critical bottleneck requiring urgent advances in energy catalysis. Although ZnIn2S4 (ZIS) exhibits favourable visible light absorption, it is plagued by severe bulk charge carrier recombination and scarce accessible surface‐active sites.
