Multiscale Architecture and Mechanics of the Cell Nucleus: Implications for Disease, Bioengineering and Nanomedicine

open access: yesAdvanced Science, EarlyView.
Nuclear mechanical properties are inherently scale‐dependent, arising from a hierarchical architecture that spans DNA, chromatin, the nuclear envelope, and condensates. Experimental techniques and theoretical models are integrated into a cohesive multiscale framework linking nanoscale structural features to organelle‐level mechanical behavior.

Displacement Monitoring of Stacked Piezoelectric Actuator by Observing Induced Charge

open access: yesInternational Journal of Automation Technology, 2008
This paper deals with condition monitoring of a piezoelectric actuator using induced charge for precision positioning. When conductive plates are attached on each end of the piezoelectric actuator to which voltage is applied, charges induced in plates are proportional to internal charge, which indicates piezoelectric actuator displacement.

Flexoelectricity in Photoconversion: Fundamentals, Materials, and Outlooks

open access: yesAdvanced Science, EarlyView.
Mechanical bending of a flexible cantilever induces a strain gradient in the photoactive material. The resulting flexoelectric field couples with photovoltaic and photoconductive effects, modulating charge generation, separation, and collection. A comparative analysis of oxide perovskites, halide perovskites, and two‐dimensional materials is presented,
