Copper Catalyzed Anisotropic Dissolution of Silicon in HF–HCl Solutions: Metal‐Assisted Chemical Etching Without Additional Oxidant

open access: yesEuropean Journal of Inorganic Chemistry, Volume 29, Issue 5, 9 February 2026.
Metal‐assisted chemical etching without an oxidant? We report an unexpected Cu2+‐catalyzed anisotropic etching of silicon in HF–HCl solutions. Despite the low redox potential of Cu2+, pyramidal surface structures are generated without a distinctive additional oxidizing agent.

Distribution of Voltage‐Gated Sodium Channels and Scaffolding Proteins on Vestibular Calyx Ending Delineates the Axon Initial Segment

open access: yesJournal of Comparative Neurology, Volume 534, Issue 2, February 2026.
Various sodium channel isoforms and their scaffolding proteins are found in four different microdomains in vestibular calyx‐bearing afferents. These microdomains serve different purposes, analogous to the heminode, axon initial segment, and synaptic domains of other types of sensory afferents.

MRI Safety Considerations for Permanent Magnet Implants in Muscle

open access: yesJournal of Magnetic Resonance Imaging, Volume 63, Issue 2, Page 563-573, February 2026.
ABSTRACT Background Permanent magnet implants are used with several medical and assistive devices, such as cochlear implants, dental attachments, and prosthetic control, but raise caution for MR imaging. Previous work has evaluated several magnet implants for position and magnetization stability, as well as for image artifacts under MRI.
