Co‐Firing Slow Solidification Process for Growing Indium‐Doped Cs3Cu2I5 Single Crystals With Record‐Breaking X‐Ray Detection Performance

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A novel brand‐new co‐firing slow solidification process has been used to prepare Cs3Cu2I5: In single crystals (SCs), which demonstrate record‐breaking X‐ray detection performance. The regular‐shaped Cs3Cu2I5: In wafer obtains a high light yield (74 368 Ph MeV−1), which is the highest related to indium‐doped Cu‐based perovskites.

In Situ Constructed TiO2 on Ti3C2‐MXene Cathode Enables Photo‐Assisted Zn‐Ion Hybrid Microsupercapacitors With High‐Energy Density

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A strategy has been developed for the in situ constructed of TiO2 nanoparticles on a Ti3C2‐MXene cathode, which is assembled with a zinc anode to form a photo‐assisted ZIH‐MSC device. The designed light‐assisted ZIH‐MSC device achieved a wide operating voltage (1.3 V) and battery‐level energy density (97 μWh cm−2, 1 mA cm−2), overcoming the limitations

Learning Rocking Dynamics From Sparse Shake‐Table Data With Interpretable Physics‐Informed Neural Networks

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT We present a hybrid interpretable Physics‐Informed Neural Network Long‐Short Term Memory (Hybrid PINN LSTM) framework for predicting the seismic response of rocking blocks. Existing analytical models rely on uncertain idealizations, while purely data‐driven and machine‐learning approaches lack physical consistency and interpretability.
