Revealing a Pathway for Low‐Temperature Recrystallization in Germanium

open access: yesAdvanced Science, EarlyView.
This study reports the discovery that energy transferred to electrons and atoms by highly ionizing ions results in a disorder‐order (amorphous‐crystalline) phase transformation in noncrystalline (amorphous) Ge. This discovery unlocks low‐temperature recrystallization pathways in Ge, offering a nonthermal strategy for fabricating Ge‐based devices that ...

Regulating Enzyme Activity via Microaggregates Mediated by Phase Separation

open access: yesAdvanced Science, EarlyView.
An enzyme‐sequestration strategy for combating postoperative pancreatic fistula (POPF) is developed, employing a D‐peptide called DPMD to induce liquid–solid phase separation (LSPS) of pancreatic proteases. This LSPS‐driven microaggregate approach effectively isolates trypsin and chymotrypsin from their substrates, thereby reducing pancreatic fluid ...

Reversing Hydrogen‐Related Loss in α‐Ta Thin Films for Quantum Device Fabrication

open access: yesAdvanced Science, EarlyView.
α‐Tantalum is one of the best materials for superconducting quantum computers because of its stable, low microwave‐loss oxide. However, excessive amounts of hydrogen can enter the material during fabrication. This study shows that hydrogen degrades quantum device performance, while annealing the device in ultra‐high vacuum removes hydrogen and fully ...

An Ultra‐Selective and Humidity‐Resistant Room‐Temperature‐Operated NO2 Sensor Based on Black TiO2

open access: yesAdvanced Science, EarlyView.
A room‐temperature‐operated NO2 sensor that achieves ultrahigh selectivity and humidity resistance is developed using black TiO2 for the first time in this work. A portable sensing equipment capable of recognizing NO2 from a mixed atmosphere with several common interfering gases and identifying real environmental differences is developed ...

Magnetic Fe3O4 Nanoparticles Modified Hydroxyapatite Whisker: A Novel Framework with Superior Osteogenic Efficacy

open access: yesAdvanced Science, EarlyView.
A novel magneto‐active bone regeneration framework was engineered by integrating Fe3O4 nanoparticles with hydroxyapatite whiskers (HAw/Fe3O4). This composite acquired magnetic responsivity, enabling programmable microstructural alignment and amplified mechanobiological cues under magnetic fields, significantly enhancing osteogenesis and bone ...
