Nanostructured Multilayer Coatings for Spatial Filtering [PDF]

Advanced Optical Materials, 2021
AbstractSpatial filtering is an important mechanism to improve the spatial quality of laser beams. Typically, a confocal arrangement of lenses with a diaphragm in the focal plane is used for intracavity spatial filtering. Such conventional filtering requires access to the far‐field domain.

Titanium Dioxide Covalently Immobilized Citric Acid (TiO2‐CA) Nanohybrid Coating of Neurovascular Flow Diverter to Improve Antithrombogenic and Pro‐Endothelialization Properties

Advanced Materials Interfaces, 2023
Braided neurovascular flow diverters (FDs) have revolutionized the treatment of aneurysms. However, dual antiplatelet therapy is mandatory for patients with FDs, which increases the risk of adverse side effects like bleeding complications.
