Dr. S. Gupta, Associate Professor from the Physics and Astronomy Department,
published an Invited Featured Article in a world reputed and high impact factor journal namely, Materials Research Society (MRS) Bulletin, March Issue, Vol. 39 (2014) (http://journals.cambridge.org/action/displayAbstract?fromPage=online&aid=9202063&utm_source=Issue_Alert&utm_medium=Email&utm_campaign=MRS) in an important area of Materials Research entitled "Topological twist on materials science", co-authored with a collaborator from Los Alamos National laboratory, Condensed-Matter Theoretical Division. One of the significances of this work lies in an emerging paradigm of
topology/geometry → property → functionality that goes beyond the traditional
microscopic structure → property → functionality relationship.
For a brief abstract, page one is attached. The website is for accessing the full article.
The primary objective of this article is twofold: to address the key concept of topology that
impacts materials science in a major way and to convey the excitement to the materials
community of recent signifi cant advances in our understanding of the important topological
notions in a wide class of materials with potential technological applications. A paradigm of
topology/geometry → property → functionality is emerging that goes beyond the traditional
microscopic structure → property → functionality relationship. The new approach delineates
the active roles of topology and geometry in design, fabrication, characterization, and
predictive modeling of novel materials properties and multifunctionalities. After introducing
the essentials of topology and geometry, we elucidate these concepts through a gamut of
nanocarbon allotropes of de novo carbons, hierarchical self-assembled soft- and biomaterials,
supramolecular assemblies, and nanoporous materials. Applications of these topological
materials range from sensing, energy storage/conversion, and catalysis to nanomedicine.
