Photonic Crystal Enhanced Microscopy on a 2D Photonic Crystal Surface

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This work demonstrates the design, fabrication, and the first‐time test of a 2D photonic crystal surface for photonic resonator absorption microscopy. The designed surface uniformly enhances electromagnetic near fields, achieving > 100% improved detecting uniformity for surface‐captured AuNPs from a blocking biosensor assay aimed for detecting SARS‐CoV‐

Internationalisation of companies and local upgrading of peripheries - The Example of VW Navarre in the European automobile production system [PDF]

open access: yes
Recently we find two main issues in the current debate on globalized localities: the first issue concerns itself with the fragmentation and relocation of value chains, chain governance and upgrading, focussing on supply chains between different companies.

Development of Laterally Graded X‐Ray Multilayer Optics

open access: yesAdvanced Materials Technologies, EarlyView.
This work presents the development of laterally graded X‐ray multilayer optics with both constant and variable lateral gradients. By precisely controlling substrate speed profiles and mask design, these multilayers achieve highly accurate lateral gradients and excellent sagittal thickness uniformity, making them ideal for spectroscopy application at ...
