Abstract: Versatile applications and broad interest in amorphous electrode materials, especially the nickel-phosphorus coatings, primarily results from their unique properties and low-production costs in comparison to precious metals. This paper discusses the most important research conducted over several years into the Me-P layers, in particular the Ni-P and Ni-Me-P ones, which led to only partial understanding of these amorphous alloys. Methods of increasing the catalytic activity of the Ni-P layers in the process of electroevolution of hydrogen are also discussed because the electrolytic layers of amorphous nickel still seem to be the promising electrode material.

Abstract: Nanomaterial based electrochemical method gain tremendous interest for the detection of biomolecules due to high sensitivity, selectivity, and low fabrication cost. High surface to volume ratio, excellent electrocatalytic properties of the nanomaterials plays important role for the sensitive and selective detection of biomolecules. For electrochemical biosensors, proper control of chemical, electrochemical and physical properties, as well as their functionalization and surface immobilization significantly influences the overall performance. This chapter gives an overview of the importance of the development of nanomaterials based electrochemical biosensors; particularly direct electrooxidation-or electroreduction-based biosensors, catalysis-based biosensors, and label-based affinity biosensors. In addition, fabrication methods including modification of electrode surface with nanomaterials, tailoring their physico-chemical properties, and functionalization with chemicals or biomolecules are also highlighted.

Abstract: Titanium based anodes are widely used in chlori-alkali industry. Two kinds of titanium based anodes were characterized by using XRD and SEM. The test results of their electrocatalytic properties showed that the nanosize crystals have great effect on the anode’s polarization behaviors and accelerated stability life. The anode with higher content of Ta possessed a smaller crystal size and better electrocatalys
