Towards adaptive radiotherapy: Comparing HyperSight and standard CBCT reconstructions on a C‐Arm Linac

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Background Cone‐beam computed tomography (CBCT) is integral to image‐guided radiation therapy and increasingly used for adaptive radiotherapy and CBCT‐based dose calculation. Conventional kV‐CBCT systems on C‐arm TrueBeam linacs with Feldkamp–Davis–Kress (FDK) reconstruction have historically been limited by reduced Hounsfield Unit (HU ...

Imaging the Thickness‐Dependent Formation of Schottky Barriers in Metal–Semiconductor van der Waals Heterostructures

Advanced Functional Materials, Volume 36, Issue 74, 14 September 2026.
Using nanobeam photoemission, we demonstrate imaging of the in‐plane and out‐of‐plane electric field landscape within a metal–semiconductor van der Waals heterostructure. We provide evidence for Schottky barrier formation that depends on the semiconductor thickness. ABSTRACT Achieving high‐performance optoelectronic devices based on two‐dimensional van

Resolving the Structural Duality of Graphene Grain Boundaries

Advanced Materials, Volume 38, Issue 51, 11 September 2026.
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.

Spin‐Split Edge States in Metal‐Supported Graphene Nanoislands Obtained by CVD

Advanced Materials, Volume 38, Issue 51, 11 September 2026.
Combining STM measurements and ab‐initio calculations, we show that zig‐zag edges in graphene nanoislands grown on Ni(111) by CVD retrieve their spin‐polarized edge states after intercalation of a few monolayers of Au. ABSTRACT Spin‐split states localized on zigzag edges have been predicted for different free‐standing graphene nanostructures.

Graphene (0002)/Diamond (111) Heterojunction with High Piezoresistive Response

Advanced Science, Volume 13, Issue 50, 7 September 2026.
Graphene/diamond heterostructures show promise as silicon alternatives for semiconductors, but high‐quality integration is challenging. Thermal electron irradiation enables covalent bonding; lonsdaleite acts as an intermediate. The heterostructure exhibits a high piezoresistive response (gauge factor −1149) associated with electron‐rich layers and ...
