Magnetic properties of materials for MR engineering, micro-MR and beyond

open access: yes, 2014
We present the results of a systematic measurement of the magnetic susceptibility of small material samples in a 9.4 T MRI scanner. We measured many of the most widely used materials in MR engineering and MR micro technology, including various polymers ...

Stretchable p/n‐Pair Thermoelectric Fibers Based on Core (Ag)–Shell (Ag2Se) Structure for Wearable Electronics

open access: yesAdvanced Functional Materials, EarlyView.
Stretchable p/n‐pair Ag@Ag2Se TE fibers are developed for next‐generation fiber‐based electronics. The TE fibers maintain excellent electrical conductivity and a high Seebeck coefficient under strain. Integrated into textiles, they enable simultaneous temperature and strain sensing, as well as energy harvesting, offering great potential for ...

Targeting microplastic particles in the void of diluted suspensions

open access: yesEnvironment International, 2019
Accumulation of microplastic in the environment and food chain will be a grand challenge for our society. Polyurethanes are widely used synthetic polymers in medical (e.g. catheters) and industrial products (especially as foams).

Robust and Reversible Thermofluorescence in Solvent‐Free Thermoplastic Polyurethane Composites

open access: yesAdvanced Functional Materials, EarlyView.
Thermofluorescent polymer composites with high‐contrast optical outputs are prepared by solvent‐free blending of indenoquinacridone dye into a thermoplastic polyurethane matrix. The temperature‐dependent fluorescence originates from aggregation–dissociation of the dye molecules, regulated by competing hydrogen bonds from the polymer matrix.

Adaptive 4D‐Printed Vascular Stents With Low‐Temperature‐Activated and Intelligent Deployment

open access: yesAdvanced Functional Materials, EarlyView.
Microarchitected coronary artery stents were fabricated using a polycaprolactone (PCL)‐based shape memory polymer (SMP) composite via projection micro‐stereolithography (PµSL) 4D printing. By incorporating diethyl phthalate (DEP) as a plasticizer, the thermal transition temperature (Ttran) was modulated to about 37°C, enabling rapid and autonomous ...
