| Abstract | Ti4+ was introduced onto the surface of 3-aminopropyltriethoxysilane (denoted as APTS; a silane coupling agent; commercial name: KH550) by surface-modification technology to afford a precursor of nanoscale cross-linker. The as-obtained precursor of nanoscale cross-linker was further transformed to a Ti-based nanoscale cross-linker (denoted as Ti-NC) by hydrolysis and condensation in association with self-aggregation. The microstructure of the Ti-NC crosslinking guar gum gel was characterised by field emission scanning electron microscopy. Moreover, the effects of the as-prepared Ti-NC on the thermal stability, rheological behaviour, and proppant-carrying ability of guar gum fracturing fluid were investigated with boric acid and TiCl4 as the controls. Results indicate that the as-prepared Ti-NC has a sphere-like shape and a size of 6–13 nm. In the meantime, the guar gum gel cross-linked by Ti-NC exhibits better thermal stability, rheological behaviour, and proppant-carrying ability than the ones cross-linked by TiCl4 or boric acid, which indicates that the as-prepared Ti-NC could find promising application in enhancing the oil recovery of the low-permeability reservoir. This is because Ti-NC contributes to enhancing the inter-molecular cross-linking rather than intra-molecular cross-linking of guar gum molecular chains and yielding a tight three-dimensional network structure in the cross-linked guar gum gel. |

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.
