| Abstract | By an in-situ seeding synthetic route, with biocompatible reagents being used, walnut kernel-like Ag nanostructures (Ag nanowalnuts) composed of nanoplates were fabricated. The in-situ formation of seeds and introduction of complex [Ag3(C6H5O7)n+1]3n−were indispensable steps for this kind of self-assembled nanostructure. The size of Ag nanowalnuts was in the range of 200–400 nm and the thickness of a single nanoplate was about 30 nm. The morphology of nanoplates was of variety, and their surface was bumpy. Such Ag nanostructures with rough surface and high curvature provided plenty of ‘hot spots’ on a single particle for surface-enhanced Raman scattering (SERS) enhancement. Experimental results indicated that the Ag nanowalnuts offered great surface enhancement for 4-mercaptobenzoic acid and malachite green molecules. The limit of detection was low to 10−10 and 10−8 M, respectively. |

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.
