| Abstract | Herein, we report for the first time a facile and cost-efficient synthesis of metal oxide nanostructures comprised of nanorods type without the use of any additive. Nd(OH) and Nd O nanorods were obtained by ultrasound wave assisted pulse electrochemical deposition in a Nd(NO ) ·6H O nitrate bath. In addition, the interconnected nanorods were mesoporous leading to large electrochemical active sites for the redox reaction and fast ion transport within the Nd O nanorods. Furthermore, for improving the electrochemical performance of conductive polymer, hybrid POAP/Nd O films have then been fabricated by POAP electropolymerization in the presence of Nd O nanorods as active electrodes for electrochemical supercapacitors. Surface and electrochemical analyses have been used for characterization of Nd O and POAP/Nd O composite films. Different electrochemical methods including galvanostatic charge discharge experiments, cyclic voltammetry and electrochemical impedance spectroscopy have been applied to study the system performance. Prepared composite film exhibited a significantly high specific capacity, high rate capability and excellent cycling stability. Importantly, electrochemical investigation show that POAP/Nd O nanorods composite material has better properties than POAP without Nd O nanorods, suggesting it can be used as supercapacitor electrode material with excellent specific capacitance (379Fg ) which indicates this material is a promising electrode material for energy storage applications in high-performance pseudocapacitors. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
