Characterization of Complex Stacking of Semiconductors Through Near Field Imaging and Spectroscopy

open access: yesAdvanced Materials, Volume 38, Issue 7, 2 February 2026.
SNOM imaging and spectroscopy on a mechanically cleaved facet is used to characterize the different layers of complex epitaxial heterostructures composed of a type II superlattice and highly doped semiconductors. Both the geometrical parameters of the stack and the optical properties of the individual layers and of the interfaces are retrieved, as well

Full Crystallographic Imaging of Hexagonal Boron Nitride Monolayers with Phonon‐Enhanced Sum‐Frequency Microscopy

open access: yesAdvanced Materials, Volume 38, Issue 7, 2 February 2026.
A nonlinear optical microscopy technique is introduced that enables rapid imaging of hexagonal boron nitride monolayers, which are usually optically invisible. The nonlinear mixing of mid‐infrared and visible laser pulses enables full crystallographic imaging through phase‐resolved sum‐frequency generation microscopy, where the resonant excitation of a

Autonomization of Microvascular Free Flaps in Reconstructive Surgery: A Narrative Review

open access: yesMicrosurgery, Volume 46, Issue 2, February 2026.
ABSTRACT Background Microvascular free tissue transfer is a key technique in reconstructive surgery, enabling functional and aesthetic restoration of complex defects. While initial flap survival relies on the vascular pedicle, some flaps may become independent through a process known as autonomization, where new vascular connections form between the ...

Microimaging Spectroscopy of Carbonaceous Chondrites and Comparison to the Spectral Diversity of Asteroids

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract Primitive asteroids and carbonaceous chondrites (CCs) record the history of processes in the early solar system. Visible and shortwave infrared (VSWIR) spectroscopy of primitive asteroids and bulk‐powdered CCs has identified shared spectral features suggestive of shared parent body origins.

Origin of the Bulge Topography Within Caloris Basin, Mercury

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract Caloris basin on Mercury has a massive circular bulge topography imprinted with unique fault sets. A variety of deformational processes have been proposed to have influenced their formation, including both global contraction and basin evolution, as well as the deposition and weight of the volcanic infill.
