| Abstract | Serial diffraction of proteins requires an injection method to deliver analyte molecules—preferably uncharged, fully hydrated, spatially oriented, and with high flux—into a focused probe beam of electrons or X-rays that is only a few tens of microns in diameter. This work examines conventional Rayleigh sources and electrospray-assisted Rayleigh sources as to their suitability for this task. A comparison is made and conclusions drawn on the basis of time-resolved optical images of the droplet streams produced by these sources. Straight-line periodic streams of monodisperse droplets were generated with both sources, achieving droplet diameters of 4 and 1 micrometer, respectively, for the conventional and electrospray-assisted versions. Shrinkage of droplets by evaporation is discussed and quantified. It is shown experimentally that proteins pass undamaged through a conventional Rayleigh droplet source. |

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.
