Chitin‐Derived Carbon‐Metal Functional Materials

open access: yesAdvanced Functional Materials, EarlyView.
Functional carbon materials are synthesized from combination of biopolymer (chitin) and iron precursors. The resultant material exhibits superior surface area and adsorptive properties compared to carbon materials synthesized directly from pure chitin.

Multicomponent Peptide‐MXene‐Hyaluronic Acid Hydrogel as a Conductive Scaffold for Enhanced Fibroblast Proliferation and Migration Under Electrical Stimulation

open access: yesAdvanced Healthcare Materials, EarlyView.
An electrically conductive FmocFF/MXene/hyaluronic acid hydrogel combines extracellular matrix‐like architecture, self‐healing behavior, oxidation‐resistant conductivity, and biochemical cues in a single scaffold. By enabling physiologically relevant electrical stimulation, the platform enhances fibroblast attachment, proliferation, and migration ...

Stability of Medicinal Nanoemulsions to Spaceflight: Insights From the StarMed Experiment

open access: yesAdvanced Healthcare Materials, EarlyView.
Chitosan‐coated melatonin nanoemulsions (MN) recovered from a sounding rocket mission preserve droplet size and controlled‐release behavior, whereas uncoated nanoemulsions show ageing‐driven droplet growth and increased accessible drug fraction. Simple polymer coatings thus enhance the flight resilience of liquid space medicines under cumulative launch

Miniature Soft Robot With Magnetically Reprogrammable Surgical Functions

open access: yesAdvanced Materials, EarlyView.
Miniature soft robots have great prospects to revolutionize minimally invasive treatments. Here we present a miniature soft robot, which can be reprogrammed to perform five surgical functionalities with six‐degrees‐of‐freedom motions. This soft robot can prospectively make minimally invasive surgery considerably safer and painless, and enable ...

Leaftronics: Bio‐Fractal Scaffolds From Leaf Venation for Low‐Waste Electronics

open access: yesAdvanced Materials, EarlyView.
“Leaftronics” transforms naturally evolved leaf venation into quasi‐fractal scaffolds for sustainable electronics. Polymer‐infiltrated leaf skeletons can be used to fabricate ultra‐smooth, reflow‐ and thin‐film‐compatible decomposable substrates, while making the same lignocellulose networks conducting results in flexible transparent electrodes.
