Magnetic and Crystal Symmetry Control on Spin Hall Conductivity in Altermagnets

Advanced Science, EarlyView.
Crystal structures and schematic illustrations of the spin Hall effect (SHE) in altermagnets. High‐symmetry RuO2 exhibits conventional SHE, while tilted RuO2 shows trivial unconventional SHE (USHE) caused by structural tilting. CrSb and MnTe, with reduced magnetic symmetry, display intrinsic USHE arising from symmetry‐driven spin–momentum locking ...

Atomic‐Scale Insights into Yttrium‐Induced Grain Boundary Structure Modification in Al2O3

Advanced Science, EarlyView.
Using advanced STEM characterization combined with NNP‐based MCMD calculations, it is revealed that Y segregation at ∑13 Al2O3 GB involves not only simple substitution of Y for Al atoms but also structural adaptation with a change in GB atomic density, leading to minimized excess volume and lowest GB energy.

A theoretical and flight test study of pressure fluctuations under a turbulent boundary layer. Part 2: Flight test study [PDF]

The study of pressure fluctuations under a turbulent boundary layer was undertaken with the objective of extending previous work to lower frequencies. Wind tunnel and flight test measurements are invalid at low frequencies because of extraneous acoustic ...

pH/ROS‐Responsive Injectable Hydrogel Co‐Loaded with B7‐H3 Blocker and NETs Suppressor Boosts OSCC Synergistic Immunotherapy

Advanced Science, EarlyView.
A pH/ROS‐dual‐responsive injectable hydrogel, formed by dynamic boronic ester and Schiff base crosslinking, co‐delivers enoblituzumab (B7‐H3 blocker) and Cl‐amidine (NETs suppressor). Via localized intratumoral delivery, it synergistically reprograms the immunosuppressive tumor microenvironment, overcomes T cell infiltration barriers, restores ...

AI‐Driven Acceleration of Fluorescence Probe Discovery

Advanced Science, EarlyView.
We present PROBY, an AI model trained on large‐scale datasets to predict key photophysical properties and accelerate the discovery of target‐specific fluorescent probes. By screening a target‐annotated library, PROBY identifies candidate probes for diverse targets and could guide probe optimization, enabling a range of in vitro and in vivo imaging ...
