NanoTechnology: Materials, Processes & Devices

Electrode surface structure and functional modification with higher catalytic response are of great interest in many technologies. This work aims at designing highly efficient nanostructured gold- based electrochemical catalyst. Using the calixarene-capped gold nanoclusters as the construction unit, we report on the formation of gold films with nanoporous structure via hydrogen-bubble templating under electrochemically reducing conditions. The resulting nanoporous gold (NPG) assembly possesses the highest aspect ratio (defined as the ratio of the pore size to the wall thickness)...

Dopamine (DA) plays a significant role in the central nervous system, the loss of which is linked to various problems, e.g., schizophrenia, drug addiction and Parkinsons disease. Accordingly, the development of sensitive and selective detection method for DA is of great interest. Electrochemical DA detection has gained increasing attention due to its operation simplicity and rapid response. Despite these advantages, electrochemical methods often lack...

While the transition metal oxides and dichacogenides have been extensively used as sensing materials, the transition metal diborides (TMDBs) have not been explored to any appreciable extent. As a class, TMDBs possess a variety of unique properties, including very high melting points, high thermal and electrical conductivities, and good corrosion resistances, and therefore hold promise as materials for the sensing of harmful gases or at elevated temperatures....

Paper electronics have attracted researchers’ attention in recent years for its potential advantage of disposability, foldability, low density and low cost. In our previous studies, we have shown a drastically different approach by a direct-write laser patterning process on paper to realize various basic device applications, such as a foldable triboelectricity generator and a folded supercapacitor as the potential paper-based power source for paper electronics, a wireless...
