Comparative Study of Planar Octahedron Molecular Structure via Eccentric Invariants
Molecules, 2023 A branch of graph theory that makes use of a molecular graph is called chemical graph theory. Chemical graph theory is used to depict a chemical molecule. A graph is connected if there is an edge between every pair of vertices.

Classification of integrable discrete equations of octahedron type [PDF]
, 2010 We use the consistency approach to classify discrete integrable 3D equations of the octahedron type. They are naturally treated on the root lattice $Q(A_3)$ and are consistent on the multidimensional lattice $Q(A_N)$. Our list includes the most prominent

Control of geometry and stability of tensegrities in the Octahedron and X-Octahedron families
Computers & StructuresTensegrity structures obtained from the same connectivity patterns are said to belong to families. The Octahedron and X-Octahedron families are examples of these. In the literature, little attention has been paid to how the final geometries of the equilibrium forms of the members of both families are obtained.

Advanced Functional Materials, EarlyView.This work explores Li‐substituted P2 layered oxides for Na‐ion batteries by crystallographic and electrochemical studies. The effect of lithium on superstructure orderings, on phase transitions during synthesis and electrochemical cycling and on the interplay of O‐ versus TM‐redox is revealed via various advanced techniques, including semi‐simultaneous

First facets of the octahedron
Discrete Mathematics, 1974 AbstractA procedure is given for identifying the facets of the octahedron that are first intersected upon extending the edge of a polyhedral cone. The information generated by this procedure can be exploited to advantage by cut-search procedures for zero-one integer programming. Results are given which make it possible to determine the first two facets

Advanced Functional Materials, EarlyView.The THz drive of the Mott insulating state of a rare‐earth nickelate induces instantaneous insulator‐metal transition via quantum tunneling of valence electrons across the bandgap. This transition is pure electronic and highly non‐thermal, which may find its applications in ultrafast opto‐electronics with enhanced performance and minimal device size ...

The 4th Dimension. Wittgenstein on Colour and Imagination [PDF]
, 2002 In this paper I first discuss the colour-octahedron and the position of this model as an idealized system with respect to the remarks on colour-concepts in Remarks on Colour (RC).

Engineering Strategies for 2D Layered Tin Halide Perovskite Field‐Effect Transistors
Advanced Functional Materials, EarlyView.2D halide perovskites are promising candidates for field‐effect transistor (FET) applications due to their high stability and suppressed ion migration in the presence of bulky organic spacers. This review systematically summarizes the optimization engineering strategies of 2D perovskite FETs and future challenges, which provide guidance for developing ...

Structural and magnetic aspects of the metal insulator transition in Ca$_{2-x}$Sr$_x$RuO$_4$
, 2000 The phase diagram of Ca$_{2-x}$Sr$_x$RuO$_4$ has been studied by neutron diffraction on powder and single-crystalline samples. The experiments reveal antiferromagnetic order and structural distortions characterized by tilts and rotations of the RuO$_6 ...
