Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced 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.

Block Copolymer Microcapsules with Perpendicularly‐Perforated Ultrathin Membranes for Controlled Transmembrane Transport

open access: yesAdvanced Functional Materials, EarlyView.
Block copolymer microcapsules with ultrathin, perpendicularly perforated membranes are developed through double emulsions, initiated by the diffusion of water into single emulsions. Both shell thickness and channel diameter can be systematically tuned, offering precision in molecular sieving and significantly enhanced permeation rates.
