Temperature‐Dependent Surface Anisotropy in (110) Epitaxial Rare Earth Iron Garnet Films

Small, Volume 20, Issue 52, December 27, 2024.
A thickness series of epitaxial rare‐earth iron garnet thin films on the (110) plane is prepared to investigate the surface effect on magnetic anisotropy. Here, the out‐of‐plane inversion symmetry breaking at a surface with C2v symmetry shows a temperature‐dependent surface contribution to anisotropy with both an in‐plane and out‐of‐plane component and

Gain Enhancement and Ground Plane Immunity of Mechanically Driven Thin‐Film Bulk Acoustic Resonator Magnetoelectric Antenna Arrays

Advanced Functional Materials, Volume 34, Issue 39, September 25, 2024.
Thin‐film bulk acoustic resonator(FBAR) magnetoelectric(ME) antenna arrays utilize magnetic dipoles for radiation, delivering superior gain, and efficiency. As array element increases, performance is boosted by enhanced magnetic moment, while maintaining impedance matching and quality factor.

Human brain dynamics dissociate early perceptual and late motor‐related stages of affordance processing

European Journal of Neuroscience, Volume 60, Issue 4, Page 4639-4660, August 2024.
Abstract Affordances, the opportunities for action offered by the environment to an agent, are vital for meaningful behaviour and exist in every interaction with the environment. There is an ongoing debate in the field about whether the perception of affordances is an automated process.

Aluminium Nitride Solidly Mounted BAW Resonators with Iridium Electrodes [PDF]

, 2008
In this work we investigated the performance of aluminium nitride (AlN)-based solidly mounted resonators (SMR) made with iridium (Ir) bottom electrodes. Ir/AlN/metal stacks were grown on top of insulating Bragg mirrors composed of alternate λ/4 layers of

Alkyne Cyclotrimerisation, Acyclic Oligomerisation, and Transfer Hydrogenation Catalysed by a Titanium(IV) Phosphinoaryloxide Complex and its Redox Chemistry

European Journal of Inorganic Chemistry, Volume 27, Issue 19, July 1, 2024.
The phosphinoaryloxide‐based titanium(IV) complex (ArPO)2TiIVCl2 (ArPO−=2,4‐tBu2‐6‐(PPh2)C6H2O−) was found to catalyse the cyclotrimerisation, the acyclic oligomerisation, and/or the hydrogenation of alkynes in the presence of magnesium in dependence of the alkyne used. The electrochemistry of this complex was investigated and its reduction yielded the

Effect of Hydrogel Matrix and Fluid Shear Stress on the Behavioral Regulation of Mesenchymal Stem Cells

Small Structures, Volume 5, Issue 5, May 2024.
In order to mimic the microenvironment of mesenchymal stem cells growth in vivo, herein, a microsystem is proposed that combines hydrogel matrix with gigahertz acoustic streaming, which can realize the regulation of cell behaviors by three mechanical factors of matrix stiffness, fluid shear stress, and matrix roughness. Development of a micromodel that
