Bioresorbable Mo–W Electrodes: Toward an Extended Operational Lifetime Through Controlled Alloying and Oxide Coating Engineering

open access: yesAdvanced Materials Interfaces, EarlyView.
Bioresorbable electrochemical sensors face instability in biofluids. Although alloys can mitigate rapid in vivo dissolution, Mo–W remains underexplored for sensing. This work engineers Mo–W films with a nanocrystalline oxide coating, improving stability and enabling reliable oxygen and pH sensing for up to 10 days, highlighting their potential for ...

Passivated SiC Surfaces for Photonic and Quantum Applications: Balancing Chemical Stability and Surface Luminescence

open access: yesAdvanced Materials Interfaces, EarlyView.
Low‐temperature passivation of SiC reveals that optical surface quality and chemical stability are not directly correlated. Ar plasma‐treated and SiNx‐passivated surfaces yield the lowest photoluminescence background, whereas CF4 plasma and ALD‐grown dielectrics introduce higher emission.

Mechanically Robust MXene‐Metal Polyphenol Network Hybrid Interfaces for Multifunctional Protection of Keratin Fibers

open access: yesAdvanced Materials Interfaces, EarlyView.
Hair keratin fibers inevitably deteriorate under UV exposure, heat, and dryness. A robust composite coating assembles delaminated Ti3C2 MXene nanosheets onto keratin surfaces through biocompatible metal‐polyphenol networks of EGCG. This hybrid layer simultaneously screens UV, dissipates heat, reinforces mechanical strength, suppresses static charge ...
