Crop genetic resource policy: the role of ex situ genebanks [PDF]
The world-wide capacity of genebanks for ex situ conservation of crop genetic resources has increased greatly since the 1970s, improving the access of crop breeders to landraces and wild and weedy relatives.

Ex citu διατήρηση και επανεισαγωγές [PDF]
, 2014 Η ex situ (εκτός τόπου) διατήρηση αποτελεί έναν από τους βασικούς πυλώνες διατήρησης της βιοποικιλότητας. Μέσω αυτής δίνεται η δυνατότητα στον άνθρωπο να προστατεύσει είδη τα οποία αδυνατούν πλέον να επιβιώσουν στο φυσικό τους περιβάλλον κυρίως λόγω των ...

Advanced Materials, EarlyView.Bioorthogonal chemistry was applied to intracellularly photoactivate Doxorubicin (Dox) using gold nanostars (AuNSt) and near‐infrared (NIR) light. Two prodrugs were used: one photoactivatable, masked with 2‐nitrobenzyl carbamate (proDox1) and another photolabile, masked with 2‐nitrobenzyl diol (proDox2), which was attached to the AuNSt surface.

Ex situ διατήρηση απειλούμενων πληθυσμών: μέθοδοι για την αποφυγή της γενετικής προσαρμογής τους στις συνθήκες αιχμαλωσίας [PDF]
, 2018 Οι παρόντες ρυθμοί εξαφάνισης ειδών έχουν αναδείξει την ex situ διατήρηση ως μια δημοφιλή λύση «τελευταίας στιγμής» για πολλά είδη. Ο στόχος της γενετικής διαχείρισης είναι η διατήρηση της δημογραφικής σταθερότητας και η εξουδετέρωση επιβλαβών γενετικών ...

Resolving the Structural Duality of Graphene Grain Boundaries
Advanced Materials, EarlyView.Cantilever ncAFM resolves the atomic structure of grain boundaries in graphene, revealing coexisting stable and metastable types. Both contain pentagon/heptagon defects, but metastable GBs show irregular geometries. Modeling shows metastable GBs form under compression, exhibiting vertical corrugation, while stable GBs are flat.

Solvent‐Free Thermal Defect Engineering in Molecular Frameworks With Volatile Linkers
Advanced Materials, EarlyView.Thermal removal of neutral volatile linkers enables precise and solvent‐free generation of metal vacancies in MOFs. This strategy affords redox‐stable, coordinatively unsaturated FeII sites with tunable spin, ligand coordination, and catalytic behavior. The approach offers a general route to design defect‐functional materials through local coordination

Advanced Materials, EarlyView.Ball‐milling Cu‐based metallic glasses with ceria creates a unique nanostructure where metallic glass particles are wrapped by CeO2 nanoparticles. The intimate integration triggers copper state reorganization during reaction and aging, boosting CO oxidation and COPrOx activity.
