Evolutionary radiation of large‐bodied gorgonopsians from the lower Abrahamskraal formation of South Africa

open access: yesThe Anatomical Record, EarlyView.
Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

How do secondary schools in England talk about modern languages? A corpus‐assisted discourse analysis of school websites

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Situating the study within an ecological perspective on language education, this article examines how secondary schools in England present Modern Languages (MLs) on official school websites. Focusing on 44 schools in Local Authorities with the lowest percentage average entry for the Languages pillar of the EBacc, we built a text database ...

Halide perovskites in wide‐spectrum photodetection

open access: yesBulletin of the Korean Chemical Society, EarlyView.
Recent advances in perovskite‐based photodetectors (PPDs), phototransistors, and photoconductors are technically discussed in this review. Moreover, the mechanism behind different harvesting processes in perovskite following the energy of photons is explained, where the gamma or x‐rays are ionizing.

Co‐Firing Slow Solidification Process for Growing Indium‐Doped Cs3Cu2I5 Single Crystals With Record‐Breaking X‐Ray Detection Performance

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A novel brand‐new co‐firing slow solidification process has been used to prepare Cs3Cu2I5: In single crystals (SCs), which demonstrate record‐breaking X‐ray detection performance. The regular‐shaped Cs3Cu2I5: In wafer obtains a high light yield (74 368 Ph MeV−1), which is the highest related to indium‐doped Cu‐based perovskites.

Nanofiber PVA‐Based Membranes Incorporating Functionalized Spanish Broom Derivatives for Sustainable Water Purification

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study investigates Spanish broom (Spartium junceum) as a renewable source for electrospun composite membranes in sustainable water purification. MCC and biochar were functionalized with eco‐friendly precursors and nanomaterials (i.e., HNT, β‐CDs) to develop hybrid PVA nanofiber composites.
