Wide Temperature Zero Thermal Expansion in Al Matrix Composites with High Thermal Conductivity

Advanced Science, EarlyView.
Strain engineering strategy is implemented on the negative thermal expansion (NTE) phase Zn1.6Mg0.4P2O7 within composites, where Al matrix‐induced compressive strain drives uniform polyhedral and unit cell evolution, thereby enabling broad and consistent thermal compensation efficacy and obtaining good thermal performance.

Ultrafast Hot‐Carrier Cooling in CsPbBr3 Supercrystals via Long‐Range Electronic Coupling

Advanced Science, EarlyView.
CsPbBr3 supercrystal self‐assembly, which induces long‐range electronic coupling, enables spatial carrier delocalization that accelerates carrier‐LO phonon scattering and weakens the Auger heating. These effects enable ultrafast, excitation‐intensity‐independent hot‐carrier cooling, offering a trade‐off‐free strategy for high‐performance perovskite ...

Multiplexed acoustic microscopy.

, 1995
There is much biological evidence that mechanical forces play a significant role in controlling normal cell growth and proliferation. This evidence has motivated many researchers to use scanning acoustic microscopes to study the mechanical properties of ...

Photoelectric‐Coupled Ferroelectric Heterojunctions for Ultrahigh NO2 Sensing With Polarization‐Memory‐Assisted Interfacial Modulation

Advanced Science, EarlyView.
This study demonstrates a Bi2WO6/SrBi2Ta2O9 heterojunction where light‐driven ferroelectric polarization reversal couples with persistent photoconductivity, enabling exclusive NO2 selective room‐temperature sensing. The device achieves a two‐order‐of‐magnitude sensitivity enhancement over an unpolarized device, a sub‐ppb detection limit, and robust ...

Microblasting Wound Dressings Mechanically Disrupt Polymicrobial Biofilms to Enhance Healing in Treatment‐Resistant Wounds

Advanced Science, EarlyView.
Treatment‐resistant wounds caused by polymicrobial biofilms are refractory to conventional therapies due to the dense extracellular matrices. We developed μBLAST, a microblasting wound dressing that combines MnO2‐doped biosilica and a H2O2‐releasing mesh to generate localized oxygen microbubbles that mechanically disrupt biofilms.
