Uranium Doped Gallium Nitride Epitaxial Thin Films

Advanced Electronic Materials, Volume 12, Issue 12, 22 June 2026.
Uranium was controllably added to gallium nitride using molecular beam epitaxy. The uranium atoms segregated into vertically oriented regions with higher doping levels. Concentrations up to a few percent were achieved without showing significant degradation in the crystalline quality or optical characteristics. Low electrical resistivity was maintained

Synthesis and Characterization of Highly Conductive Cobalt Phthalocyanine‐Based Metal–Organic Framework

Advanced Electronic Materials, Volume 12, Issue 12, 22 June 2026.
A two‐dimensional (2D) layered material, CoPc‐MOF, with a cobalt phthalocyanine backbone as its structural unit, was successfully synthesized. CoPc‐MOF adopts a crystal structure analogous to a Lieb lattice, which is a type of Dirac material. CoPc‐MOF exhibits exceptionally high electrical conductivity for an organic semiconductor, which likely ...

Early evolutionary history of the seed

Biological Reviews, Volume 101, Issue 3, Page 1511-1553, June 2026.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...
