Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

open access: yesAdvanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

The Effect of Flotation Reagents Addition (MIBC and PAX) on the Relative Permittivity Value Using 2-Electrode Capacitance Sensor

open access: yesProcedia Engineering, 2017
Abstract In general, frother and collector are used as reagents to obtain an optimum condition in flotation processes. In this study, the effect of methyl isobutyl carbinol (MIBC) frother and potassium amyl xanthate (PAX) collector on the relative permittivity value using 2-electrode capacitance sensor was conducted. The objective of this study is to

Spatially Modulated Morphotropic Phase Boundaries in a Compressively Strained Multiferroic Thin Film

open access: yesAdvanced 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 ...
