Revocable Attribute-Based Encryption Scheme With Efficient Deduplication for Ehealth Systems
IEEE Access, 2019 The deduplication based on attribute-based encryption can be well used in eHealth systems to save storage space and share medical records. However, the excessive computation costs of existing schemes lead to inefficient deduplication.

Angewandte Chemie, EarlyView.Dibenzo[b,d]selenophene (DBSe) π‐core fusion enables rapid triplet–singlet interconversion while preserving the narrowband emission features of multi‐resonance thermally activated delayed fluorescence (MR‐TADF) luminogens. Combined with peripheral donor engineering, this strategy enables systematic emission tuning from green to red, leading to highly ...
