New PCBs-degrading and hexavalent chromium-resistant bacteria isolated from Lake Mariout, Egypt
Egyptian Journal of Aquatic Research, 2023 Polychlorinated biphenyls (PCBs) are persistent organic pollutants. They were widely used and distributed in the environment causing endocrine disruption, carcinogenicity, and immunotoxicity.

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.

Advanced Functional Materials, EarlyView.We introduce a capillary‐filtering‐based particle‐filling (CFPF) process that simultaneously forms vertical thermal pathways and electrical vias within µ‐pores. In situ microfluidic analysis reveals that capillary‐driven velocity gradients generate vorticity that governs µ‐platelet rotation and vertical alignment.
