3D Printable Magnetic Soft Actuators–Ink Formulation, Rheological Characterization, and Hydrogel Actuator Prototypes

open access: yesMacromolecular Materials and Engineering, EarlyView.
Magnetic inks for direct ink writing (DIW), a 3D printing technique, are formulated based on acrylamide, iron oxide, and the rheology modifier laponite. They have shear thinning and thixotropic properties. Prototypes printed by DIW, followed by thermal curing, could be magnetically actuated.

Two‐Cycle Strain‐Induced Crystallization Behavior of Peroxide Cross‐Linked Solid Guayule Natural Rubber

open access: yesMacromolecular Materials and Engineering, EarlyView.
For the first time, peroxide cross‐linked solid green guayule natural rubber is shown to exhibit highly reproducible cyclic strain‐induced crystallization behavior, consistent with its tensile properties. Using in situ tensile testing and synchrotron wide‐angle X‐ray diffraction over two cycles, this study enhances understanding of its mechanical ...

Solvent and Ion‐Mediated Behavior of a Thermoresponsive Brush: Specific Ion Effects in Methanol‐Water Electrolytes

open access: yesMacromolecular Rapid Communications, EarlyView.
The manifestation of specific ion effects in methanol‐water mixtures on polymer brush exemplars is explored. Spectroscopic ellipsometry and neutron reflectometry revealed solvent‐driven LCST changes in a thermoresponsive brush, which is also readily influenced by the presence of electrolytes.

Comparison of secondary radiation dose between pencil beam scanning and scattered delivery for proton and VHEE radiotherapy

open access: yesMedical Physics, EarlyView.
Abstract Background Very high‐energy electrons (VHEEs) in radiotherapy may offer several potential advantages over conventional electron beams and other techniques, for example, the fact that they can be used at ultra‐high dose rates (UHDRs), therefore enabling FLASH radiotherapy.

A comparative analysis of GEANT4, MCNP6 and FLUKA on proton‐induced gamma‐ray simulation

open access: yesMedical Physics, EarlyView.
Abstract BackgroundPrecise range verification is essential in proton therapy to minimize treatment margins due to the steep dose fall‐off of proton beams. The emission of secondary radiation from nuclear reactions between incident particles and tissues stands out as a promising method for range verification.
