Advanced Healthcare Materials, EarlyView.Coagulative granular hydrogels are composed of packed thrombin‐functionalized microgels that catalyze the conversion of fibrinogen into a secondary fibrin network, filling the interstitial voids. This bio‐inspired approach stabilizes the biomaterial to match the robustness of bulk hydrogels without compromising injectability, mimicking the initial ...

A Novel Decellularized Fibrocartilage Graft Promotes Tympanic Membrane Repair
Advanced Healthcare Materials, EarlyView.An off‐the‐shelf decellularized porcine meniscus fibrocartilage graft (MEND) is engineered for pediatric tympanoplasty. Featuring a microchannel architecture that promotes host cell invasion, MEND rapidly closes tympanic membrane perforations and fully remodels in vivo, outperforming fascia and matching cartilage grafts while avoiding donor‐site ...

Adaptive Control Scheme for Space Debris Capture in the Presence of Mass and Inertia Uncertainty
IEEE AccessThis paper proposes an adaptive control scheme for capturing uncooperative space debris having uncertain inertial parameters. Debris parameters may be unknown or uncertain due to limited data or changes in orbit due to collisions.

Unifying Space: Australia Needs a Whole of Government Space Policy
, 2021 • Australia’s past and current space experience is characterised by the intertwined threads of civilian, defence and alliance interests. Defence has dominated much of Australia’s efforts in space, while in turn civilian space has been used to cement ...

Engineering of Glioblastoma‐Derived Biomimetic Vesicles and Their Structural and Molecular Features
Advanced Healthcare Materials, EarlyView.ABSTRACT Biomimetic nanosystems and vesicles have arisen as a novel approach to design vesicular transport systems with diverse therapeutic potential. The ‘biomimetic’ strategy involves the integration of cell membrane components into lipid bilayers, conferring them with biological properties originating from the cell of origin. Until now, most studies

Advanced Healthcare Materials, EarlyView.A thermo‐responsive poly(2‐oxazoline)‐based injectable formulation is developed to modulate intraocular pressure (IOP) in both normal and hypotonic eyes. By adjusting the PEG content, the aggregation behavior is finely tuned, enabling IOP elevation without long‐term deposition.
