ChemSusChem, Volume 19, Issue 8, 28 April 2026.The growing demand for lithium‐ion batteries in the European Union contributes to critical raw material scarcity. This challenge can be addressed by establishing a circular economy, making use of highly efficient and economical recycling processes. The efficiency of these processes depends on high‐purity material streams and thus on the availability of

Aggregate, Volume 7, Issue 2, February 2026.Solvent‐driven reversible “crystal to crystal” transformation of copper(I)‐iodine clusters with significant difference of luminescent color and quantum yields is reported. The differences before and after this transformation may be related to more efficient thermally activated delayed fluorescence (TADF) achieved by cluster 1 through space charge ...

International Journal of Distributed Sensor Networks, 2016 The existing proxy signature schemes with the proxy revocation function are proven to be malleable and do not possess strong unforgeability. Motivated by these concerns, a new proxy signature scheme with fast revocation is proposed, and it can be proved ...

On the Quantum Security of OCB
IACR Transactions on Symmetric Cryptology, 2022 The OCB mode of operation for block ciphers has three variants, OCB1, OCB2 and OCB3. OCB1 and OCB3 can be used as secure authenticated encryption schemes whereas OCB2 has been shown to be classically insecure (Inoue et al., Crypto 2019).
