Decomposing a Planar Graph into Degenerate Graphs
Journal of Combinatorial Theory, Series B, 1995 A graph \(G\) is \(k\)-degenerate if every subgraph of \(G\) has a vertex of degree less than \(k\). The author proves that the vertex set of any planar graph can be decomposed into two sets such that one of them induces a 3-degenerate graph and the other induces a 2-degenerate graph.

Advanced Functional Materials, EarlyView.An entropy‐tuned niobium‐based oxide (ETNO) anode for fast‐charging lithium‐ion batteries are presented, engineered via multi‐cation doping. The synergistic effects of entropy tuning result in excellent rate capability and long‐term durability under ultrafast charging conditions.

Planar lattices and planar graphs
Journal of Combinatorial Theory, Series B, 1976 AbstractIt is shown that a finite lattice is planar if and only if the (undirected) graph obtained from its (Hasse) diagram by adding an edge between its least and greatest elements is a planar graph.

Advanced Functional Materials, EarlyView.Charge carrier concentration and mobility in TiO2, ZrO2, and HfO2 powder films are experimentally mapped as a function of temperature. The results uncover polaron‐mediated transport regimes and field‐activated conduction, enabling the design of oxide‐based electronic and energy devices with thermally tunable functionality.

Advanced Functional Materials, EarlyView.A reproducible synthesis to control 3D/0D phase ratios via water‐tuned solvent–antisolvent methods is presented. Enhanced scintillation yield and ultrafast decay are achieved. Defect‐driven emission mechanisms are revealed through cathodoluminescence and radioluminescence, shedding light on the underexplored role of the 0D Cs4PbBr6 and mixed 0D/3D ...

Advanced Functional Materials, EarlyView.Electromagnetic interference (EMI) shields consisting of polylactic acid (PLA) in layers with different concentrations of multiwalled carbon nanotubes (MWCNT) are produced using additive manufacturing. The permittivity function of layers with different filler concentrations is learned using data of homogeneous and randomly ordered shields.
