Advanced Science, EarlyView.This study constructs a dual‐scale Ag‐based catalyst on CeO2 nanorods via a facet‐guided strategy. This catalyst can induce a cascaded orbital hybridization effect, which synergistically optimizes oxygen vacancy stability, CO desorption kinetics, and charge transfer efficiency.

On the Edge-Hyper-Hamiltonian Laceability of Balanced Hypercubes
Discussiones Mathematicae Graph Theory, 2016 The balanced hypercube BHn, defined by Wu and Huang, is a variant of the hypercube network Qn, and has been proved to have better properties than Qn with the same number of links and processors.

Hamiltonian paths and hamiltonian connectivity in graphs
Discrete Mathematics, 1993 A degree and neighborhood type condition on independent triples of vertices of a graph \(G\) that implies \(G\) is hamiltonian-connected is given. In particular, the following is proved. If \(G\) is a 3-connected graph of order \(n\) such that \(d(u) + d(v) + d(w)-| N(u) \cap N(v) \cap N(w) | \geq n+1,\) then \(G\) is hamiltonian-connected.

A Proton‐Intercalation Pathway Realizes Long‐Life Manganese‐Ion Hybrid Batteries With Layered KV3O8
Advanced Science, EarlyView.This is the first study to demonstrate layered monoclinic KV3O8 as a highly stable cathode material for aqueous Mn‐based hybrid batteries, exhibiting excellent cycling stability with 88.0% capacity retention after 3600 cycles. The proton storage mechanism is systematically elucidated through comprehensive spectroscopic analyses, further supported by ...

Euclidean tours in fairy chess [PDF]
Notes on Number Theory and Discrete MathematicsThe present paper aims to generalize the Knight's tour problem for k-dimensional grids of the form {0,1}ᵏ by considering other fairy chess leapers. Accordingly, we constructively show the existence of closed tours in 2×2×...×2 (k times) chessboards ...
