Atomic Interlayer Mo–N4 Sites Enable Rapid Charge Transfer and Efficient CO2 Photoreduction
Advanced Science, EarlyView.This work achieved efficient CO2 activation and ultrafast interlayer electron transport in a 2D COF by constructing atomic‐level Mo‐N4‐induced interlayer electron bridges (IEB), thereby kinetically and thermodynamically co‐driving the photocatalytic coupling of CO2 reduction with 4‐methoxybenzyl alcohol oxidation.

Modular chromatic number of $C_m square P_n$ [PDF]
Transactions on Combinatorics, 2013 A modular $k$-coloring, $kge 2,$ of a graph $G$ without isolated vertices is a coloring of the vertices of $G$ with the elements in $mathbb{Z}_k$ having the property that for every two adjacent vertices of $G,$ the sums of the colors of the neighbors are

Bounds on the complex zeros of (Di)Chromatic polynomials and Potts-model partition functions
, 2001 We show that there exist universal constants C(r) such that, for all loopless graphs G of maximum degree less than or equal to r, the zeros (real or complex) of the chromatic polynomial P-G(q) lie in the disc \q\ 7.963907r.

Star multigraphs with three vertices of maximum degree. [PDF]
, 1986 The graphs we consider here are either simple graphs, that is they have no loops or multiple edges, or are multigraphs, that is they may have more than one edge joining a pair of vertices, but again have no loops.

Advanced Science, EarlyView.A scalable radiative cooling fabric engineered with a multi‐layer assembly core–shell structure and integrated photoluminescent materials is reported. The fabric exhibits remarkable environmental stability, including UV resistance, mechanical durability, hydrophobicity, stain resistance, thermal stability, and flame retardancy, demonstrating its ...

Advanced Science, EarlyView.A rotational energy harvesting device that successfully reconciles high power density with mechanical durability through a hybrid sliding‐and‐bouncing kinematic mechanism is reported. The success reported in our paper includes addressing a dilemma where enhanced electrical output comes at the cost of increased friction and wear, limiting the practical ...

The incidence chromatic number of some graph
International Journal of Mathematics and Mathematical Sciences, 2005 The concept of the incidence chromatic number of a graph was introduced by Brualdi and Massey (1993). They conjectured that every graph G can be incidence colored with Δ(G)+2 colors.

On the adaptable chromatic number of graphs
, 2008 The adaptable chromatic number of a graph G is the smallest integer k such that for any edge k-colouring of G there exists a vertex k-colouring of G in which the same colour never appears on an edge and both its endpoints.

Advanced Science, EarlyView.A physics‐based framework resolving graphite phase‐separation dynamics establishes a predictive, degradation‐aware fast‐charging methodology for commercial Li‐ion batteries. The resulting model‐informed protocol achieves 20%–80% state‐of‐charge in 14 min while matching the long‐term degradation of a commercial 25‐minute EV strategy.
