Ossiculoplasty for Malleus Bar with Incudostapedial Disconnection and Fused Incudomalleolar Joint

Case Reports in Otolaryngology, 2020
Malleus bar is an abnormal bony connection between the malleus handle and the posterior wall of the tympanic cavity. We report a patient with a malleus bar and another malformation of the ossicles.

Individualization and Purification of Carbon Nanothreads

Small, EarlyView.
Reductive dissolution enables the solution processing of carbon nitride nanothreads into individualized nanothreads that can be assembled into ultrathin films. The resulting interconnected networks exhibit weakly semiconducting behavior, with the conductivity decreasing by only ∼40% from room temperature to 2 K.

Three-dimensional vibration of the malleus and incus in the living gerbil [PDF]

, 2014
: In previous studies, 3D motion of the middle-ear ossicles in cat and human was explored, but models for hearing research have shifted in the last few decades to smaller mammals, and gerbil, in particular, has become a popular hearing model.

Loss Analysis of Low Bandgap (Ag,Cu)(In,Ga)Se2 Solar Cells for Tandem Applications

Small, EarlyView.
A complete loss analysis has been carried out on the state‐of‐the‐art 1.0 eV bandgap (Ag,Cu)(In,Ga)Se2 solar cells, which are of interest for tandem devices. The most significant loss mechanisms are found in the open‐circuit voltage, due to non‐radiative losses in the chalcopyrite absorber, and in the fill factor, caused by space‐charge region ...

Multi‐Scale Mechanical Behavior of Additive‐Manufactured 316L Stainless Steel Processed by Severe Plastic Deformation

steel research international, EarlyView.
The multi‐scale mechanical behavior of additive‐manufactured 316L stainless steel processed by directed energy deposition and high‐pressure torsion is explored. The influence of torsional strain on strength and microstructural evolution is revealed, indicating progressive grain refinement in the ultrafine regime, reaching strength levels nearing 1800 ...

Histopathological differences in bony destruction of malleus and incus following mastoidectomy [PDF]

, 2010
Objectives:Upon direct inspection of surgically removed ossicles from the ears of patients with long-term post-mastoidectomy cavity problems, the extent of malleus destruction often appears greater in patients with a longer duration of cavity problems ...
