International Journal of Electrical Power & Energy SystemsThe hybrid modular multilevel converter (MMC) may experience an inter-group capacitor voltage imbalance between full-bridge submodule (FBSM) and half-bridge submodule (HBSM) groups during over-modulation operation. To address this issue, this paper first

Laser‐Induced Graphene from Waste Almond Shells
Advanced Functional Materials, EarlyView.Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.
