| Abstract | Summary form only given. The field of complex plasmas has witnessed almost exponential growth since the discovery in 1994 of the self-assembly of ordered structures (Coulomb crystals) within a controlled lab environment. Recently there has been enormous interest in the static and dynamic behavior of 2- and 3D dust clusters consisting of a finite number of charged, ordered dust grains within a horizontal confinement. Both the resulting structures and the dynamic behavior of such small dust clusters (N<100) is now under intense investigation. It has recently been shown employing a numerical simulation that under certain conditions a structural phase transition can occur, reordering a 2D dust crystal from one exhibiting hexagonal lattice structure to that showing a spherical structure consisting of concentric rings. Such phase transitions appear to occur preferentially within the outer layers of larger dust clusters, where the Debye length and the confining potential both vary in a manner which is not yet completely understood. This paper examines such structural phase transitions, analyzing them quantitatively. Experimental data are also compared to simulation results. |

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.
