| Abstract | The interaction between parallel planes, immersed in a solution from which r-mer molecules are adsorbed, is treated theoretically using the multilayer lattice model for adsorption from solution. The surface excess of the configurational free energy is calculated as a function of the plane separation. The model is applicable both in dilute and concentrated solutions. Results are presented for solutions composed of monomers plus dimers and monomers plus flexible tetramers. The influence of the following parameters is shown: strength of adsorption, segment interchange energy, and concentration of the solution. Adsorption of r-mers with one end-segment preferentially adsorbed leads to a repulsive energy between the parallel planes at small separations. An increase in the length of the r-mer or in the quantity of r-mer adsorbed increases the repulsive energy at any separation. Adsorption of r-mers with every segment preferentially adsorbed from solution gives an attractive energy which increases as the planes approach. |

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.
