Managing and visualising geochemical data for tephra correlation with the IntChron Integration Tool

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT There is now a wealth of glass‐shard geochemical data for volcanic ash (tephra) layers from a wide range of volcanoes and eruptions, providing invaluable datasets for tephrochronology. However, compilation of published data to assess tephra correlations leads to large files and requires careful management.

Nitrogen‐doped graphene quantum dots tune the mineral, acid, and sugar profile of raisins in a cultivar‐specific manner

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Carbon dots are emerging as low‐toxicity nano‐biostimulants, but their effects on the integrated mineral, organic‐acid, and sugar profiles of grape berries remain poorly characterized, especially in indigenous Vitis vinifera L. cultivars.

Nanomedicine applications in lymphoma: Advancing precision diagnostics, targeted therapeutics, and prospective developments

open access: yesVIEW, EarlyView.
Lymphoma is a group of blood cancers that can appear in lymph nodes, blood, bone marrow, spleen, liver, or the central nervous system, which makes drug delivery and disease monitoring difficult. This review summarizes how nanomedicine technologies may improve targeted treatment and imaging, while carefully separating approved or guideline‐supported ...

Interventional oncology in children: Where are we now?

open access: yesJournal of Medical Imaging and Radiation Oncology, EarlyView.
Abstract Paediatric Interventional Oncology (IO) lags behind adult IO due to a scarcity of specific outcome data. The suboptimal way to evolve this field is relying heavily on adult experiences. The distinct tumour types prevalent in children, such as extracranial germ cell tumours, sarcomas, and neuroblastoma, differ strongly from those found in ...
