We introduce an additively manufactured bioreactor with a perfusion flow system and integrated temperature and pH sensors for skeletal muscle tissue biofabrication. The bioreactor's performance was evaluated by assessing the viability, spreading of the myoblast cells in a printed scaffold, and contraction of the isolated murine musculi interossei ...

Investigation of Ultrasonic Guided Waves Interacting With Piezoelectric Transducers
Ultrasonic guided waves (UGW) can be used to inspect and monitor a structure from a single test location. Piezoelectric transducers are commonly dry-coupled with force to the surface of the waveguide in order to excite UGWs. These UGWs propagating within the waveguide will interact and reflect from known features, thus possible damage could be detected.

Ultrathin and Flexible Organic Light‐Addressable Potentiometric Sensors
The first ultrathin, fully organic, and flexible light‐addressable potentiometric sensor (LAPS) is demonstrated. With a thickness of only 2.3–2.9 µm, this standalone film offers sensitivity to electrolyte potential and stable performance for over 170 days.

High‐pressure recrystallization provides a reproducible route to high‐quality CsPbBr3${\rm CsPbBr}_{3}$ thin films. Optimized processing at 300 bar yields smooth, pinhole‐free, single‐phase 3D perovskite layers with tunable thickness, enhanced crystallinity, reduced amplified‐spontaneous‐emission threshold, improved photostability, and phase‐transition

Cascading Spin‐Orbitronic Terahertz Emission in Ferromagnet/Nonmagnet Bilayers
While the initial generation mechanism of picosecond orbital currents remains elusive, we reveal a cascading spin–orbital transport mechanism that induces optically driven terahertz emission in ferromagnet/nonmagnet heterostructures. Using a ferromagnet with strong spin–orbit coupling, we identify a thickness‐driven transition from spin‐dominated to ...
