Nanomaterials and their composites (various forms) (both inorganic and organic) are still evolving and encouraging scientist community to explore their various possibilities and applications in developing Science and technology. In this era, we are experiencing and realizing a vital role of Nanotechnology as we are seeing in smart phones, millimeter sized storage devices, micro devices, digital voice/telecommunications etc. All these developments are possible because of small matters so called “Nanoparticles”. In the same way, electrochemistry is undertaking a big role in all areas of science and engineering. For ex; Electroanalytical methods have potential advantages in (bio) chemical sensing and biomedical science. Cyclic voltammetry is a classical tool to investigate and derive the reaction mechanisms of electroactive inorganic and organic materials. This special issue of article will address the recent developments of nanomaterials and their applications in the electrochemical solid-state science. In the first article, Prof. Subramaniam et al. reported about graphene and its charge storage performance. His group found that graphene enhanced charge storage performance in the Electrochemical Double Layer Capacitors (EDLC). Secondly, Karthick et al. developed a reliable method for the green synthesis of gold nanoparticles (Au- NPs) using a medicinally valued Adhatoda vasica Nees. It is a rapid and eco-friendly method which may help researchers to synthesize Au-NPs covered with bioactive compounds and is expected to have potential applications in biomedical science. Thirdly, Felix et al. have successfully synthesized IrO2 and demonstrated it as an effective anodic electrocatalyst for the oxygen evolution reaction (OER) in solid polymer electrolyte. In the fourth article, Arockiasamy et al. deposited titanium nitride (TiN)/nickel (Ni) composite by plasma assisted metal-organic chemical vapor deposition (PAMOCVD) using organo-metallic and metal-organic complexes. They proposed that Ni/TiN composite is useful to create super hard coatings. Lastly, Sundramoorthy et al. have proposed a conducting redox-polymer coated sensor for the detection of reduced form of nicotinamide adenine dinucleotide in physiological condition with lower detection limit. This new electrode system may be useful for real-sample analysis. We kindly appreciate all of the contributors for their timely support and co-operation. We hope our articles will be useful for academic and industrial researchers.
