Orbit evolution, maintenance and disposal of SpaceChip swarms [PDF]
, 2010 The combined effect of solar radiation pressure and atmospheric drag is investigated for future mission conceptsfor swarms of satellites-on-a-chip (SpaceChips). The natural evolution of the swarm is exploited to perform spatially distributed measurements

Advanced Functional Materials, EarlyView.The hidden role of Cd segregation at grain boundaries is revealed in p‐type Mg3Sb2 by atom probe tomography and other advanced characterizations. Grain boundary Cd enrichment suppresses the SbMg+ hole‐killer formation and lowers potential barriers, enhancing electrical conductivity.

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 ...

Advanced Healthcare Materials, EarlyView.A two‐phase workflow (OFAT screening followed by central composite design) maps how processing variables tune PFCE‐PLGA nanoparticle size, dispersity, surface charge, loading, and 19F‐MRI signal. In situ, time‐resolved synchrotron SAXS tracks albumin‐corona growth on intact dispersions and reveals PFCE‐dependent adsorption pathways.

Advanced Healthcare Materials, EarlyView.The DA/VTP‐NBs selectively recognized cardiac ECs damaged by DIC and achieved cell‐level targeted imaging. Then US‐triggered controlled release successfully enabled the release of DAPA within the DA/VTP‐NBs at the site of injury. This precise on‐demand drug release approach amplifies a series of localized therapeutic effects through the mtDNA‐mediated ...
