Multiscale Analysis of Plasma-Modified Silk Fibroin and Chitosan Films

This study demonstrates that biological interactions with plasma-modified silk fibroin and chitosan surfaces are scale-dependent, revealing that bacteria respond to fine-scale topographic features while macrophages correlate with larger-scale features, thereby suggesting that tailoring surface topography to specific biological length scales is a promising strategy for developing antibacterial wound-healing materials.

Stress Asymmetry in Hard Magnetic Soft Materials

This paper demonstrates that while continuum magnetomechanical formulations for hard magnetic soft materials yield different Cauchy stress symmetries depending on whether the magnetization is described in the referential or current configuration, both formulations converge to symmetric stresses with identical equilibrium behavior when the magnetization field is at its energy-minimizing state.

A comparison of the spin-phonon behaviour of Fe2_2P-based magnetocaloric materials

This study investigates the spin-phonon behavior and magnetocaloric potential of Fe2_2P and FeMnP0.55_{0.55}Si0.45_{0.45} using magnetometry, neutron scattering, and theoretical modeling, revealing that the magnetic transitions are driven by distinct site-specific behaviors and uncorrelated magnetic processes at two length scales, which are well-supported by first-principles calculations.
