Tuning the Optoelectronic Properties of Wide Bandgap Perovskites: Data‐Driven Insights from Combinatorial Synthesis and High‐Throughput Experimentation

open access: yesAdvanced Functional Materials, EarlyView.
Combinatorial vapor deposition enables independent tuning of Cs/Pb and Br/Cl in wide‐bandgap perovskites. Automated multimodal mapping of 500+ compositions reveals a high‐energy optical transition that correlates with enhanced photoluminescence, defining a practical Cs/Pb window.

Biodynamics of the seated human body with dual-axis excitation: nonlinearity and cross-axis coupling

open access: yes, 2012
The apparent mass of the seated human body and the transmissibility to the upper-body (i.e., the spine and the pelvis) during vertical vibration excitation have been reported to have resonance frequencies around 5 Hz.

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers

open access: yesAdvanced Functional Materials, EarlyView.
We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...
