Nanoindentation in Crystal Engineering: Quantifying Mechanical Properties of Molecular Crystals
TL;DR: Through nanoindentation it is possible to correlate molecular-level properties such as crystal packing, interaction characteristics, and the inherent anisotropy with micro/macroscopic events such as desolvation, domain coexistence, layer migration, polymorphism, and solid-state reactivity.
Journal ArticleDOI
Non-covalent routes to tune the optical properties of molecular materials
TL;DR: In this paper, the authors highlight the scope and relevance of interdisciplinary and multitechnique approaches to unravel the structure-optical property relationships and also to augment the foundations of factual knowledge.
Journal ArticleDOI
Interaction anisotropy and shear instability of aspirin polymorphs established by nanoindentation
Sunil Varughese,Mangalampalli S. R. N. Kiran,Katarzyna A. Solanko,Andrew D. Bond,Upadrasta Ramamurty,Gautam R. Desiraju +5 more
TL;DR: In this article, nanoindentation is applied to the two polymorphs of aspirin to examine and differentiate their interaction anisotropy and shear instability, and different elastic moduli and hardness values are correlated with their crystal structures.
Journal ArticleDOI
Mechanical anisotropy in crystalline saccharin: nanoindentation studies
Mangalampalli S. R. N. Kiran,Sunil Varughese,C. Malla Reddy,Upadrasta Ramamurty,Gautam R. Desiraju +4 more
TL;DR: In this article, the nanoindentation technique has been employed to relate the mechanical properties of saccharin single crystals with their internal structure and to assess the mechanical anisotropy.
Journal ArticleDOI
Solvent-Dependent Coordination Polymers: Cobalt Complexes of 3,5-Dinitrobenzoic Acid and 3,5-Dinitro-4-methylbenzoic Acid with 4,4‘-Bipyrdine
TL;DR: The synthesis, structure elucidation, and analysis of the self-assembly of Co(II) complexes of 3,5-dinitrobenzoic acid and 3,4'-bipyridine with 4,4-ethyl sulfoxide have been reported, found to be dependent on the solvents employed for the synthesis of the aggregate.
