Predictions of Energy Content in Stretched Ribbons of Segmented Polymer Piezoelectrics

open access: yes, 2015
Polymer piezoelectrics such as poly vinyldene fluoride (PVDF) offer advantages such as low temperature fabrication into large area flexible sheets. A primary advantage of this is that large sheets of PVDF can be stretched into membranes to build sensors ...

Bioengineered Interfaces for Peripheral Nerve Sensory Restoration

open access: yesAdvanced Materials, EarlyView.
Half of amputees abandon their prosthetics for lack of feeling. This review charts the full path from peripheral nerve injury to restored sensation, through surgical, regenerative, noninvasive, and implanted approaches, and shows how injury type and interface material properties determine which strategy can deliver naturalistic feedback, and why ...

Epitaxially Integrated Electro‐Optic KNbO3 Thin Films on Silicon

open access: yesAdvanced Materials, EarlyView.
We demonstrate the first epitaxial integration of electro‐optic KNbO3 thin films on silicon using suboxide molecular‐beam epitaxy. Combining adsorption‐controlled molecular‐beam epitaxy, advanced characterization, and phase‐field modeling, we demonstrate phase‐pure crystalline films mirroring bulk crystals with robust Pockels response, enabling future ...

Realization of Non‐Equilibrium Wurtzite Structure in Heterovalent Ternary MgSiN2 Film Grown by Reactive Sputtering

open access: yesAdvanced Electronic Materials
The piezoelectric and ferroelectric applications of heterovalent ternary materials are not well explored. Epitaxial MgSiN2 films are grown at 600 °C on (111)Pt//(001)Al2O3 substrates by the reactive sputtering method using metallic Mg and Si under the N2

Soft and Transient Bioelectronics Enabled by Polymer‐Free Ti3C2Tx MXene Hydrogels

open access: yesAdvanced Materials, EarlyView.
We present Ti3C2Tx MXene hydrogel (MXgel) bioelectronics, a soft, flexible, and fully transient platform for high‐fidelity neural recording and stimulation. MXgel bioelectronics exhibit exceptional electrical conductivities, low electrochemical impedances, and high charge injection capacities.

Increasing Lipid Nanoparticle mRNA Copy Number Improves Transfection Potency

open access: yesAdvanced Materials, EarlyView.
As lipid nanoparticle (LNP) systems are the leading platform for in vivo nucleic acid delivery, improving transfection potency of these systems is of considerable interest. In this work, we explored a post‐mixing formulation method involving a two‐step buffer exchange that increased the number of mRNA copies within each LNP while reducing the number of

RETRACTED: Effect of Zr Doping on Structure and Ferroelectric Properties of Nanostructured Barium Titanate

open access: yesNano Select
Using soft chemistry methods, solid solutions of BaTi1‐xZrxO3 with 0 ≤ x ≤ 1 were obtained. The phase nature and features of the perovskite crystalline structure were established by x‐ray analysis and Fourier transform infrared (FTIR) spectroscopy.
