Influence of defect distribution on the reducibility of CeO2-x nanoparticles

Maria Chiara Spadaro

Ceria nanoparticles (NPs) are fundamental in heterogeneous catalysis because of their ability to store or release oxygen depending on the ambient conditions. Their oxygen storage capacity is strictly related to the exposed planes, crystallinity, density an ...

Bubble electrodeposition of gold porous nanocorals for the enzymatic and non-enzymatic detection of glucose

Sandro Carrara, Irene Taurino

Au nanocorals are grown on gold screen-printed electrodes (SPEs) by using a novel and simple one-step electro-deposition process. Scanning electron microscopy was used for the morphological characterization. The devices were assembled on a three-electrode ...
