Modification of Metal Microelectrodes with Vertical Graphene Structure for Enhanced Electrochemical Detection of Dopamine

open access: yesAdvanced Materials Interfaces, EarlyView.
In this article, vertical graphene‐modified microelectrodes (VGMEs) are fabricated by modifying vertical graphene on different types of metal microelectrodes (Au, Ti, Ag, and W) for enhanced electrochemical detection of DA. Moreover, the sensing performance on dopamine concentrations is explored with different electrochemical methods, including EIS, CV,

Chitosan‐Graft‐Gelatin Hydrogel Containing Bromothymol Blue as a Food Spoilage Indicator for Intelligent Food Packaging

open access: yesAdvanced Materials Interfaces, EarlyView.
A chitosan‐graft‐gelatin hydrogel, incorporating a pH‐responsive dye, bromothymol blue, as a colorimetric freshness indicator is introduced to monitor the spoilage of chicken breasts. The hydrogel indicates microbial activity, and the production of carbon dioxide due to deteriorating food freshness via a change in pH, and serves as a smart and visual ...

In Situ Manipulation of Growth Mechanisms in the Vapor–Solid–Solid Growth of GaP Nanowires

open access: yesAdvanced Materials Interfaces, EarlyView.
The direct observation of the Ni‐assisted GaP nanowire growth process via transmission electron microscopy reveals two different growth mechanisms by Trimethylgallium (TMGa) precursor supply variations. The decrease of TMGa flow results in the formation of Ni2P phase as growth promoters with cation exchange reaction in addition to interface diffusion ...

AFM‐Based Functional Tomography – To Mill or Not to Mill, that is the Question!

open access: yesAdvanced Materials Interfaces, EarlyView.
Complex networks of conducting domain wall interfaces exist hidden underneath the surface of ferroelectric hexagonal manganites. It reveals the morphology and conductive properties directly by 3D tomographic atomic force microscopy. It correlates the measured surface level conductance with subsurface domain wall structure, and discuss the existence ...
