Mechanical cues such as extracellular matrix stiffness and movement have a major impact on cell differentiation and function. To replicate these biological features in vitro, soft substrata with tunable elasticity and the possibility for controlled surface translocation are desirable. Here we report on the use of ultra-soft (Young's modulus <100 kPa) PDMS-based magnetoactive elastomers (MAE) as...

Background: In this study the basic radiation properties of N-isopropylacrylamaide polymer gel dosimeter were determined together with verification of its soft tissue equivalency. Materials and Methods: The NIPAM gel was prepared and irradiated approximately 2 h after manufacturing. The magnetic resonance (MR) images were made 24 h after irradiation. The nuclear magnetic resonance (NMR) respons...

This paper reports the measurement of magnetic properties of the soft magnetic composite material SOMALOY 500 in a square sample under different patterns of flux density with 2D magnetic excitations. The test system, principle of measurement, magnetic power loss calculation, and methods of correction for misalignment of H surface sensing coils are presented. The experimental results show that a...

In this paper, we examine the observational soft Xray flares and the relationship with photospheric vector magnetograms in the active region (NOAA 7070). We analyze the soft X-ray flare on Feb. 24-25, 1992, especially the pre-flare and the relationship with the highly sheared photospheric vector magnetic field near the photospheric magnetic neutral line. We find that the initial reconnection of...

Magnetic Soft Robots In article number 2201813, Venkatsubramanian Kalpathy Venkiteswaran and co-workers develop a biocompatible soft polymer film for coating the outer surface of robot which can be controlled using magnetic fields. The Chitosan-Glycerol endows with ability locomotion on confined 3D surfaces through formation hydrogen bonds mucus-covered biological surfaces.

In this paper, the focus is on a new kind of biodegradable semi-interpenetrating polymer networks, which derived from ɛ-caprolactone, lactide, 1,4-butane diisocyanate and ethylenediamine and also its potential has been investigated in soft tissue engineering applications. The polymers were characterized by nuclear magnetic resonance (NMR) spectrometry, fourier transform infrared spectroscopy (F...

Properties of soft biological tissues are increasingly used in medical diagnosis to detect various abnormalities, for example, in liver fibrosis or breast tumors. It is well known that mechanical stiffness of human organs can be obtained from organ responses to shear stress waves through Magnetic Resonance Elastography. The Local Interaction Simulation Approach is proposed for effective modelli...

A family of multilayer microwires with hard/soft biphase magnetic behavior is here introduced. The microwires consist of a Fe63Pt27Si10 hard magnetic nucleus and a Fe20Ni80 soft outer shell separated by an intermediate insulating Pyrex glass microtube. The precursor FePtSi glass-coated microwire is fabricated by quenching and drawing technique, and its L10 hard magnetic phase is grown by postan...

Fe-based metallic glasses such as FINEMET, NANOPERM and HITPERM usually produced from amorphous precursors in various forms have been intensively studied over the past thirty years, because these materials exhibit a unique combination of soft magnetic properties [1], which is very interesting from a scientifi c point of view. The application of these materials at elevated temperatures is determ...
