Magnetoelastic Effect in Ni-Zn Ferrite Under Torque Operation.
Materials (Basel)
December 2024
Institute of Metrology and Biomedical Engineering, Warsaw University of Technology, A. Boboli 8, 02-525 Warsaw, Poland.
The magnetoelastic effect is known as the dependence between the magnetic properties of the material and applied mechanical stress. The stress might not be applied directly but rather generated by the applied torque. This creates the possibility of developing a torque-sensing device based on the magnetoelastic effect.

Applying long wavelength periodic potentials on quantum materials has recently been demonstrated to be a promising pathway for engineering novel quantum phases of matter. Here, we utilize twisted bilayer boron nitride (BN) as a moiré substrate for band structure engineering. Small-angle-twisted bilayer BN is endowed with periodically arranged up and down polar domains, which imprints a periodic electrostatic potential on a target two-dimensional (2D) material placed on top.

In ambient mass spectrometry, the performance in direct in situ analysis applications has been hindered by the lack of efficient ion-transferring technique between the atmosphere pressure ionization source and the mass analyzer. Building upon the hybrid concept of a stack ring ion guide and multipole ion guide, this study proposes the concept of a reconfigurable twisted dipole ion guide (TDIG) that enables flexible ion transfer between atmosphere and vacuum. Initially, theoretical and numerical studies were conducted to understand the basic ion confining principle of the twisted dipole ion guide, revealing its unique merits in long-distance flexible ion transmission.

Background: Interventional echocardiography (IE) plays a critical role in guiding structural heart interventions. IE specialists face challenges including high radiation exposure and unfavorable ergonomics. To address these issues, a novel remote-control robotic (RCR) system for transesophageal echocardiography (TEE) control has been developed.

Article Synopsis
- Trained immunity enhances innate immune responses through cellular reprogramming, differing from adaptive immunity, which relies on memory T and B cells for long-term pathogen-specific responses.
- While there's evidence supporting the concept of trained immunity and its role in personalized medicine, significant gaps remain in understanding the mechanisms and identifying specific microbial triggers.
- The review discusses infection-induced pathways in macrophages and natural killer cells, examines the biochemical basis of trained immunity, and reflects on its therapeutic potential, risks, and future research challenges.
