Sol-Gel Derived Ferroelectric Nanoparticles Investigated by Piezoresponse Force Microscopy
, 2009 Piezoresponse force microscopy (PFM) was used to investigate the ferroelectric properties of sol-gel derived LiNbO$_3$ nanoparticles. To determine the degree of ferroelectricity we took large-area images and performed statistical image-analysis.

Advanced Functional Materials, EarlyView.Ferroelectric memcapacitors enable non‐volatile, voltage‐programmable capacitance tuning for adaptive electronics. A TiN/HfZrO/TiN device stack demonstrates more than eight stable capacitance states within a 24 pF memory window in compact 60 ×$\times$ 60 μm2$\umu{\rm m}^{2}$ devices at low operating voltages.

Some remarks on stability for a phase-field model with memory [PDF]
, 2006 The phase field system with memory can be viewed as a phenomenological extension of the classical phase equations in which memory effects have been taken into account in both fields.

Spatially Modulated Morphotropic Phase Boundaries in a Compressively Strained Multiferroic Thin Film
Advanced Functional Materials, EarlyView.ABSTRACT The coexisting rhombohedral‐like (R′, MA) and tetragonal‐like (T′, MC) monoclinic phases in compressively strained bismuth ferrite thin films exhibit exceptional piezoelectric and magnetic properties. While previous studies have largely focused on probing the morphotropic phase boundaries (MPBs) comprising ordered R′/T′ twins, their self ...

Distributed representation of pelvic floor muscles in human motor cortex
Scientific Reports, 2018 Human motor cortex can activate pelvic floor muscles (PFM), but the motor cortical representation of the PFM is not well characterized. PFM representation is thought to be focused in the supplementary motor area (SMA). Here we examine the degree to which

The Relationship Between Pelvic Floor Function and Sexual Function in Perimenopausal Women
Sexual Medicine, 2021 : Introduction: Perimenopausal women with pelvic floor dysfunction have worse sexual function than women with functional pelvic floor muscle (PFM), especially in terms of libido, orgasm, sexual satisfaction, and total Female Sexual Function Index (FSFI)
