Abstract Our daily electromagnetic environment is becoming increasingly complex with the rapid development of consumer electronics and wireless communication technologies, which in turn necessitates interference (EMI) shielding, especially for transparent components. We engineered a EMI shielding film crack-template based metallic mesh (CT-MM) that shows highly homogeneous light transmission strong microwave efficacy. The CT-MM fabricated using cost-effective lift-off method on crackle...

Microbially-synthesized protein-based materials are attractive replacements for petroleum-derived synthetic polymers. However, the high molecular weight, repetitiveness, and highly-biased amino acid composition of high-performance have restricted their production widespread use. Here we present a general strategy enhancing both strength toughness low-molecular-weight by fusing intrinsically-disordered mussel foot protein fragments to termini, thereby promoting end-to-end protein-protein...

Sustainable aqueous zinc ion batteries (AZIBs) necessitate a wide operational temperature range to ensure practicability, yet achieving this often compromises either reaction kinetics at low temperatures or cycling stability high temperatures. Here we present an electrolyte design that balances trade‐off, enhancing the and of AZIBs across −60 60 °C. Our approach incorporates silk fibroin as multifunctional additive into ZnCl2‐based “water‐in‐salt” electrolyte, which modifies both structure...
