Approach for Damage‐Free Disassembly of Highly Stressed CFRP Structures

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT In today's pursuit of sustainability, the aviation industry faces challenges in reusing materials and structural components made from carbon fiber‐reinforced polymer (CFRP). Conventional downcycling methods degrade CFRP's structural integrity by cutting load‐bearing fibers and embedding them in new matrices, reducing performance.

Multi‐Functional ZnO–Te Heterojunction Devices Enabling Compact Frequency Quadrupler

open access: yesAdvanced Functional Materials, Volume 36, Issue 42, 26 May 2026.
Wafer‐scale ZnO–Te heterojunction devices featuring tunable double negative differential transconductance (D‐NDT) are demonstrated at ≤ 200°C. Leveraging this unique characteristic, a single‐stage frequency quadrupler is realized, achieving a 64%–75% reduction in device count.

Ultrasonic Modeling of Real-Life NDT Situations: Applications and Further Developments [PDF]

open access: yes, 1996
In order to cope with real-life NDT situations, we have to develop numerical time domain modeling tools which are based on direct numerical methods because only very few idealized canonical NDT situations can be modeled with analytical methods.
