Tunable Switching Behavior of GO-Based Memristors Using Thermal Reduction

open access: yesNanomaterials, 2022
This work reports on the fabrication of a novel planar reduced graphene oxide (rGO) memristor (MR) device. For the first time in the literature, the MR tunable resistive switching behavior is controlled by the GO reduction time at a constant temperature.

Droplet microreactor for high-throughput fluorescence-based measurements of single catalyst particle acidity

open access: yesMicrosystems & Nanoengineering, 2023
The particles of heterogeneous catalysts differ greatly in size, morphology, and most importantly, in activity. Studying these catalyst particles in batch typically results in ensemble averages, without any information at the level of individual catalyst

An all-glass microfluidic network with integrated amorphous silicon photosensors for on-chip monitoring of enzymatic biochemical assay [PDF]

open access: yes, 2017
A lab-on-chip system, integrating an all-glass microfluidics and on-chip optical detection, was developed and tested. The microfluidic network is etched in a glass substrate, which is then sealed with a glass cover by direct bonding.
