We describe an unusual galvanic replacement process for facile synthesis of nickel nanostructures by using Cu as a sacrificial template in a deep eutectic solvent (DES) Ethaline. This replacement process occurred through a Galvanic exchange of [NiCl4] ions in Ethaline at 353 K with an immersed Cu substrate, which acted as both reactive template and reductant. The mechanism for this replacement ...

This paper outlines the development and hardware software integration of an instrumental setup designed towards the real-time assessment of the affective status of a computer user. This assessment is based on the measurement and digital signal analysis of three physiological variables that reflect dynamic changes of the Autonomic Nervous System (ANS): Blood Volume Pulse (BVP) measured with an i...

The purpose of this chapter is to provide the basic knowledge on batteries, which will allow for their general understanding. Therefore, after defi ning their components and structure, an overview of the quantities that characterize these storage devices will be given. Scientifi cally batteries are referred to as electrochemical or galvanic cells, due to the fact that they store electrical ener...
