Summary: The strain-driven interfacial coupling between ferromagnetic and ferroelectric constituents in magnetoelectric (ME) composites makes them potential candidates for novel multifunctional devices. ME thin-film devices have shown promising applications, with (Pb1-xZrx)TiO3 (PZT), Pb(Mg1/3Nb2/3)O-3-PbTiO3 (PMN-PT), Aluminium nitride (AlN), and Al1-xScxN as commonly used piezoelectric constituents, and FeGa, FeGaB, FeCo, FeCoB, and Metglas as commonly used magnetostrictive constituents. ME field sensors offer a limit of detection in the fT/Hz(1/2) range at the mechanical resonance frequency, with noise floors of 1-100 pT/Hz(1/2) at 1 Hz. ME antennas operate at very-high frequency and ultra-high frequency ranges, and have potential applications in biomedical devices and wearable antennas. Integrated tunable inductors and band-pass filters, along with miniaturized ME energy harvesters, are also discussed.

Summary: The authors previously introduced a novel magnetoelectric (ME) composite configuration called distributed disc structured (DDS) configuration, which can operate at high temperatures without epoxy. However, a topological study revealed that the absence of epoxy in the DDS composites resulted in material discontinuity and voids at the magnetostrictive/piezoelectric interface, negatively impacting the ME response. In this study, epoxy was used to fill the voids in the DDS composites, resulting in a remarkable improvement in the quasi-static and resonant ME measurements compared to epoxy-free counterparts.

Summary: This study investigated the development of Prochloraz resistance in Fusarium fujikuroi and analyzed the fitness of different resistant strains. The majority of the F. fujikuroi strains collected from Heilongjiang Province showed resistance to Prochloraz, with a resistance frequency of 92.1%. The resistant strains demonstrated higher disease severity and there was no cross-resistance between Prochloraz and other tested fungicides. These results indicate that Prochloraz resistance in F. fujikuroi is severe and could potentially lead to yield loss.

Summary: In this work, <001>-oriented Pb(In1/2Nb1/2)O-3-Pb(Sc1/2Nb1/2)O-3-PbTiO3 textured ceramics were fabricated by the template grain growth method. The electromechanical properties of these ceramics under different external fields were characterized and analyzed. The results showed that the dielectric constants of all textured ceramics increased with uniaxial prestress and hydrostatic pressure, but decreased with the increase of d.c. bias electric field. The textured ceramic with 3 vol. % BT templates exhibited the best stability under external fields, with less than 2% change in the electromechanical coupling factors under hydrostatic pressure increase to 100 MPa.

Summary: This study investigates a distributed six-degree-of-freedom (6-DOF) cooperative control for multiple spacecraft formation considering parametric uncertainties, external disturbances, and time-varying communication delays. Unit dual quaternions are used to describe the kinematics and dynamics models of the 6-DOF relative motion of the spacecraft. A distributed coordinated controller based on dual quaternions with time-varying communication delays is proposed. An adaptive coordinated control law is developed to compensate for parametric uncertainties and external disturbances. Numerical simulations show the effectiveness of the proposed method in cooperative control of attitude and orbit for the multi-spacecraft formation.
