ii) Part A is compulsory, which carries 25 marks. In Part A, answer all questions.
iii) In Part B, Answer any one question from each unit. Each question carries 10 marks and may have a, b as sub questions.
Part A
Define Nanomaterial.
Answer
Nanomaterials are substances with at least one dimension in the size range of 1 to 100 nanometers. At this scale, materials exhibit unique physical, chemical, and biological properties that differ significantly from their bulk counterparts due to quantum effects and increased surface-to-volume ratios.
Write a note on multiply twinned nanoparticle.
Answer
Multiply twinned nanoparticles (MTNs) are nanostructures, such as decahedra or icosahedra, formed by the assembly of several crystalline subunits joined at twin boundaries. These structures are thermodynamically stable at the nanoscale despite the internal strain caused by the geometric mismatch of the subunits, allowing them to minimize surface energy compared to single-crystal structures.
