Increased Disarray of Extracellular Matrix Collagen‐I Fiber Network and Compromised Biomechanics in Aortae From Marfan‐Syndrome Mice Assessed Through Combined Opto‐Biomechatronics

Advanced Science, EarlyView.
Combined structure‐function assessment in aortic rings from Marfan mice using MechaMorph Opto‐Biomechatronics technology relates increased elasticity (stiffness) and dynamic viscosity and less ordered extracellular matrix 3D‐structure (collagen) as potential causes for impaired Windkessel function and compromised haemodynamics in Marfan's syndrome ...

Integrated fiber-PIC synthetic aperture chip enables 2D high-resolution interferometric imaging

Optics Express
The implementation of synthetic aperture interferometry via photonic integrated circuits (PICs) holds significant potential for miniaturized high-resolution imaging systems, particularly in space optics and precision metrology. However, its advancement remains constrained by two fundamental limitations: restricted baseline reconfigurability ...

Engineering Borophene Band Structure Through Thickness

Advanced Science, EarlyView.
Borophene grown on W(110) shows a thickness‐dependent evolution of its structural and electronic properties. Surface microscopy, diffraction, XPS, and ARPES reveal distinct monolayer and bilayer phases. The formation of the second layer is accompanied by structural reconstruction, changes in chemical properties, and new ARPES features, demonstrating ...
