Programmable, very low noise current source.

A new approach for the realization of very low noise programmable current sources mainly intended for application in the field of low frequency noise measurements is proposed, based on a low noise Junction Field Effect Transistor acting as a high impedance current source and programmability is obtained by resorting to a programmable floating voltage source.

Configurable low noise amplifier for voltage noise measurements

This work proposes to employ a modular design entirely based on monolithic operational amplifiers that allows, by paralleling and/or combining in a proper way a number of identical basic amplifier blocks, to reach different compromises in terms of background noise and input capacitance while enabling, at the same time, differential measurement configurations and/ or cross correlation background noise reduction approaches.

Electrochemical Detection of p-Aminophenol by Flexible Devices Based on Multi-Wall Carbon Nanotubes Dispersed in Electrochemically Modified Nafion

Electrical measurements performed in deionized water show that the Au/Nafion/Au-MWCNTs– Nafion:Cu cells can be successfully used in order to detect the presence of p-aminophenol (PAP) in water, without the need for any supporting electrolyte.

Polypyrrole and Graphene Nanoplatelets Inks as Electrodes for Flexible Solid-State Supercapacitor

Electrochemically active conducting inks are developed starting from commercially available polypyrrole and graphene nanoplatelets blended with dodecylbenzenesulfonic acid, resulting in areal capacitance that, when obtained from about 100 mF⋅cm−2 in the sample with poly pyrrole-based electrodes, increases by a factor of about 3 when using electrodes deposited from inks containing polyp Pyrrole and graphite nanoplateles.
