| Abstract | The observation of scanning electron microscope (SEM) on a Chamidae's shell showed that the shell consists of aragonite layers and collagen protein matrix. All aragonite layers are parallel with the surface of the shell and consist of many long and thin aragonite sheets. These aragonite sheets are perpendicular to the layers where they are located. The observation also showed that the aragonite sheets in different layers possess different orientations, which compose a kind of herringbone microstructure of the sheets. More careful observation showed that the aragonite sheets consist further of lesser aragonite microsheets. The thickness of the aragonite microsheets possesses nanometer scale. The maximum pullout force of the herringbone microstructure was investigated and compared with that of the parallel microstructure based on their representative models. It showed that the herringbone microstructure can markedly increase the pullout force of the microsheets and improve the fracture toughness of the shell. |

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.
