Surprising Water Slipping Performance on Highly Hydrophilic PEG‐Derived Monolayer‐Covered Surfaces: Preparation, Mechanism, and Application

open access: yesAdvanced Functional Materials, EarlyView.
Highly hydrophilic surfaces (water contact angle, ≈17.7°) exhibiting surprising water slipping performance (sliding angle, ≈7.3°) are successfully prepared via simple chemisorption of polyethylene glycol (PEG) organosilane and subsequent alkali‐treatment.

Coupling Anodic Activity and Stability at Ni‐Based Non‐Oxide Catalysts via Coordinating Alcohol Oxidation and Oxygen Evolution

open access: yesAdvanced Functional Materials, EarlyView.
A cooperative and competitive interrelationship between alcohol oxidation (AOR) and water oxidation (OER) was observed on a typical anode catalyst of Ni2P. In situ Raman spectroscopy and electrochemical analyses revealed a specific complementary mechanism between them, in which OER and AOR critically contribute to the activity and stability of anodic ...

Double‐Interpenetrating Composite Bioink for Multi‐Component 3D Bioprinting and Biofabrication

open access: yesAdvanced Functional Materials, EarlyView.
Marine‐polysaccharides‐derived double interpenetrating network hydrogel‐based bioink, combining the attributes of physical and ionic crosslinking, enables room‐temperature bioprinting of mechanically defined structures that can be handled and are cytocompatible.

Immunodefense of the Round Window

open access: yesThe Laryngoscope, 2008
AbstractA systematic analysis using serial sectioning of the round window membrane (RWM) in the cynomolgus monkey was performed. Light and transmission electron microscopy (LM and TEM) revealed that the RWM rim may be endowed with gland‐like structures with glyco‐protein material secernated into the window niche.

Round window rupture

The Journal of Laryngology & Otology, 1981
Eight patients suffered sudden sensory neural hearing losses associated with exertion or trauma; all were found at tympanotomy to have round window membrane ruptures with leakage of perilymph. Operative findings, with audiometric, radiological and electrocohleographic results are shown.

SURGERY OF THE ROUND WINDOW

Otology & Neurotology, 1988
Tympanotomy is routinely performed in our institution to control the round window membrane for patients with recurrent sudden deafness, with Meniere-like attacks, and those with Meniere's disease. In a large number of these patients, especially those with vertigo, perilymph fistula has been diagnosed. Most patients are free of attacks after the fistula

Round window fistula

Otolaryngology–Head and Neck Surgery, 2009
A72-year-old woman was referred for a tympanic-mastoid cholesteatoma with erosion of the tegmen and right-sided complete deafness. Otoscopic examination showed near-complete atelectasis with a small tubal region perforation, scutum and facial canal erosion, absence of ossicles, and enlargement of the round window niche (Fig 1).
