An in-flight interaction of the X-29A canard and flight control system [PDF]

open access: yes
Many of today's high performance airplanes use high gain, digital flight control systems. These sytems are liable to couple with the aircraft's structural dynamics and aerodynamics to cause an aeroservoelastic interaction.

Magnetic Control of Chiral Hybridized Phonon Magnetic Moments in Ferrimagnets Fe2‐xZnxMo3O8

open access: yesAdvanced Functional Materials, EarlyView.
Helicity‐resolved magneto‐Raman spectroscopy reveals magnetic control of chiral phonon magnetic moments in polar ferrimagnet (ZnxFe2−xMo3O₈). Large spontaneous zero‐field phonon splittings, selective phonon–magnon coupling, and asymmetric Zeeman responses demonstrate that phonon chirality is governed by magnon‐phonon coupling and magnetization.

MOFs and COFs in Electronics: Bridging the Gap between Intrinsic Properties and Measured Performance

open access: yesAdvanced Functional Materials, EarlyView.
Metal‐organic frameworks (MOFs) and covalent organic frameworks (COFs) hold promise for advanced electronics. However, discrepancies in reported electrical conductivities highlight the importance of measurement methodologies. This review explores intrinsic charge transport mechanisms and extrinsic factors influencing performance, and critically ...

Hot‐Film and Calorimetric Methods With Transient Heating for Measurement of High Biofluid Flow Rate

open access: yesAdvanced Functional Materials, EarlyView.
Accurate measurement of biofluid flow rate is vital for clinical diagnostics. We propose a transient heating strategy using short thermal pulses and peak temperature tracking to enhance the flow sensitivity of the hot‐Film and calorimetric methods. Simulations show how optimal heating time maximizes sensitivity across flow rates.

Emergent Spin‐Glass Behavior in an Iron(II)‐Based Metal–Organic Framework Glass

open access: yesAdvanced Functional Materials, EarlyView.
A one‐pot, solvent‐free synthesis yields an Fe2+‐based metal‐organic framework (MOF) glass featuring a continuous random network structure. The material exhibits spin‐glass freezing at 14 K, driven by topological‐disorder and short‐range magnetic frustration, showcasing the potential of MOF glasses as a plattform for cooperative magnetic phenomena in ...
