“…Cyclic voltammograms of the electrodes in deareated PBS solutions with or without 5 mM glucose are shown in Fig 4 (the RHE scale is shown for comparison). Although the behavior of the Pt-Ni 650 and Pt-Ni 800 electrodes are similar to that of pure Pt electrodes through peak A, C, D and I [46][47][48], Ni still has its influence on the electrode behavior through peak F [49], [50,51], [52]. Peak C in Fig.…”

Fuel cells capabable of synthetic glucose catalysis have revolved around the implementation of abiotic catalysts that require extreme acid and alkaline environments. These are not compatible with implantable medical sensor systems, and hence there is a need to develop abiotic catalysts that operate at neutral pH. This paper presents structural and electrochemical characteristics of a nanoporous electrode designed for abiotic glucose oxidation in the presence of oxygen in neutral physiological media. The electrode was fabricated by annealing e-beam deposited thin films of Platinum (Pt) and Nickel (Ni) into a Pt-Ni alloy on a silicon substrate. The porous nature of the alloy enhance electrochemical properties by increasing the real surface area ~ 500 times compared to the geometric surface area of as-prepared multilayer thin films. This was reflected in the exchange current density of the electrode annealed at 800 C being twice that of the electrode annealed at 650 C. The cell voltage increase, due to the addition of dissolved physiological oxygen of 2 ppm, was about 100 ± 8 mV under a load current density of 2 µA cm-2. After running for 72 hours in a physiological saline solution with 5 mM glucose, the increase in the electrode potential was only 23 µV h 1 . These results suggest that the nanoporous Pt-Ni alloy anode offers an improved catalytic stability with time and should be a viable candidate for use in abiotic catalysed glucose fuel cell systems operating under physiological conditions.

“…nanotubes, nanowires or nanocables). This could be the main reason why after decades of researches all over the world there is still interest in studying properties of common 1-dimmensional nanomaterials [1][2][3][4]. This particularity makes materials to exhibit interesting behavior compared to bulk materials, which can be exploited in order to create more energy efficient materials, with improved magnetic properties at room temperature (i.e.…”

Synthesis of nanomaterials is one of the most researched areas. Nanomaterials are at the core of all modern nano-devices. The reduced size helps electronics to have increased performance, low energy consumption and low heat output. Properties of nanomaterials are mainly related to the involved large surface to volume ratio. Nanomaterials can be fabricated using different methods. One of the intensely used, inexpensive and with high degree of reproducibility is electrochemistry (EC), which can be used either to destroy (corrosion) or to create (thin films, nanoparticles, nanowires (NWs), etc.) materials. In this paper we focus on the effect of the electrochemical treatment (EchT) on the structural and magnetic properties of nanowires. Ni NWs were synthesized and analyzed by SQUID to study the magnetic properties induced by the EchT of the Au substrate. Ni NWs were synthesized in a gold-coated PCTE membrane using template synthesis. The EchT induced structural modifications of the Au substrate and further modifications of NWs magnetism.
