On $ h $-integral Sombor indices
AIMS MathematicsIn 2021, Ivan Gutman introduced the Sombor index, a new vertex-degree-based topological index with significant geometric meaning. This index has shown remarkable growth in research activity in recent years.

Topological aspects in a two component Bose condensed system in neutron star
, 2010 By making use of Duan-Ge's decomposition theory of gauge potential and the Duan's topological current theory proposed by Prof. Duan Yi-Shi, we study a two component superfluid Bose condensed system, which is supposed being realized in the interior of ...

Topological indices for the antiregular graphs
Le Matematiche, 2021 Summary: We determine some classical distance-based and degree-based topological indices of the connected antiregular graphs (maximally irregular graphs). More precisely, we obtain explicitly the \(k\)-Wiener index, the hyper-Wiener index, the degree distance, the Gutman index, the first, second and third Zagreb index, the reduced first and second ...

Two‐Dimensional Materials as a Multiproperty Sensing Platform
Advanced Functional Materials, EarlyView.Various sensing modalities enabled and/or enhanced by two‐dimensional (2D) materials are reviewed. The domains considered for sensing include: 1) optoelectronics, 2) quantum defects, 3) scanning probe microscopy, 4) nanomechanics, and 5) bio‐ and chemosensing.

Advanced Functional Materials, EarlyView.Dual‐phase MoC/Mo2C/CoNC nanoframes are synthesized via a MOF‐on‐MOF strategy, demonstrating a large salt adsorption capacity, a low energy consumption, and an excellent cycling stability. In situ/ex situ characterizations and DFT calculations reveal that the MoC/Mo2C dual phase transition facilitates Na+ adsorption/desorption, while interface‐induced ...

Topological Indices of Semigraph
International Journal of Engineering and Advanced Technology, 2020 Topological indices of different molecular structures has been widely studied since last many decades. These indices are treated as a score function which maps a structure to a real numerical value and this value can be used as a descriptor of the structure which helps to study the structure and under its characteristics.

Microsphere Autolithography—A Scalable Approach for Arbitrary Patterning of Dielectric Spheres
Advanced Functional Materials, EarlyView.MicroSphere Autolithography (µSAL) enables scalable fabrication of patchy particles with customizable surface motifs. Focusing light through dielectric microspheres creates well defined, tunable patches via a conformal poly(dopamine) photoresist. Nearly arbitrary surface patterns can be achieved, with the resolution set by the index contrast between ...

Topological Study of Zeolite Socony Mobil-5 via Degree-Based Topological Indices
Journal of Chemistry, 2021 Graph theory is a subdivision of discrete mathematics. In graph theory, a graph is made up of vertices connected through edges. Topological indices are numerical parameters or descriptors of graph.
