The ability to modulate the surface chemical characteristics of solid-state nanopores is of great interest as it provides the means to control the macroscopic response of nanofluidic devices. For instance, controlling ...

The main goal of enzyme immobilization is the re-use of enzymes for many reaction cycles and extended periods of time. Many novel strategies were developed during the last 20 years. The most common are thec arrier-bound ...

The blocking of ion transport at interfaces strongly limits the performance of electrochemical nanodevices for energy applications. The barrier is believed to arise from space-charge regions generated by mobile ions by ...

Graphene is a two-dimensional (2D) material composed only of carbon atoms, which has been widely studied due to its electrical, mechanical and optical properties. The combination of this material with some characterization ...

The synthesis of α-MoO3 nanoplates with a unique well-faceted rectangular morphology produced by a polymeric solution route is presented. This versatile chemical route allowed the growth of layered nanoplates on different ...

Resistive Random Access Memories (RRAMs) are based on resistive switching (RS) operation and exhibit a set of technological features that make them ideal candidates for applications related to non-volatile memories, ...

As Estruturas Metalorgânicas (MOF, do inglês Metal Organic Framework) são compostos que tem atraído bastante atenção nas últimas décadas devido as suas características de alta porosidade, cristalinidade e versatilidade ...

We describe the use of asymmetric nanopores decorated with crown ethers for constructing robust signal-responsive chemical devices. The modification of single conical nanopores with 18-crown-6 units led to a nanodevice ...

Gold is a noble metal that, in comparison with silver and copper, has the advantage of corrosion resistance. Despite its high conductivity, chemical stability and biocompatibility, gold exhibits high plasticity, which ...
