Spatially Resolved Current Density and Electrochemical Impedance Spectroscopy in PEM Fuel Cells

open access: yesFuel Cells, Volume 26, Issue 2, April 2026.
ABSTRACT The durability and efficiency of proton exchange membrane fuel cells (PEMFC) are crucial for their deployment in heavy‐duty applications. The membrane‐electrode assembly (MEA) of a PEMFC plays a central role and can be characterized using in situ methods like polarization curves, current density mapping, and electrochemical impedance ...

Malleostapedotomy in Patients With Stapes Fixation: A Systematic Review

open access: yesThe Laryngoscope, Volume 136, Issue 4, Page 1601-1613, April 2026.
This systematic review analyses the current evidence on malleostapedotomy as a primary or revision procedure in patients with stapes fixation. Twenty‐five studies comprising 632 operated ears were included. Malleostapedotomy proved to be a safe and effective alternative to incus‐anchoring stapedoplasty, with favorable hearing outcomes and a low ...

Kinetics of Elastic Recoil in the Wings of the cicada, Dundubia rufivena

open access: yesNatural Sciences, Volume 6, Issue 2, April 2026.
We quantify elastic recoil in cicada wings using high‐speed videography, revealing faster bending than torsional recoil. Wing stiffness increases when attached to the thorax, demonstrating a body‐wing spring system and highlighting that elastic recoil must be understood through whole‐organism mechanics rather than isolated wing properties.

Controlled Synthesis of a New Class of Heterostructured Metal Oxides (Cerium, Thorium, Uranium)/Calcium Fluoride Core‐Shell Nanocrystals With Atomically Coherent Interfaces

open access: yesAngewandte Chemie, Volume 138, Issue 12, 16 March 2026.
Precisely engineered heterostructured metal oxide‐based MO2 / CaF2 (M = Ce, Th, U) core‐shell nanocrystals are synthesized with atomic‐level control over size, shell thickness, and interface coherence, expanding heterostructure design principles to cerium oxide and actinide oxide systems for the first time.
