Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

Advanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

A short proof of the middle levels theorem

Discrete Analysis, 2018
A short proof of the middle-levels theorem, Discrete Analysis 2018:8, 12 pp. Let $n$ be a positive integer, and define a bipartite graph where one vertex set consists of all subsets of $\{1,2,\dots,2n+1\}$ of size $n$, the other consists of all subsets ...

Edge Disjoint Hamilton Cycles in Knödel Graphs [PDF]

Discrete Mathematics & Theoretical Computer Science, 2016
The vertices of the Knödel graph $W_{\Delta, n}$ on $n \geq 2$ vertices, $n$ even, and of maximum degree $\Delta, 1 \leq \Delta \leq \lfloor log_2(n) \rfloor$, are the pairs $(i,j)$ with $i=1,2$ and $0 \leq j \leq \frac{n}{2} -1$.

Amorphous High Entropy Alloy Nanosheets Enabling Robust Li–S Batteries

Advanced Functional Materials, EarlyView.
Amorphous ultrathin FeCoNiMoW high entropy alloy nanosheets are incorporated into the polypropylene separator of lithium‐sulfur batteries, enhancing their capacity, rate performance, and cycling stability. Abstract High‐entropy alloys (HEAs) show great potential for catalyzing complex multi‐step reactions, but optimizing their parameters, i.e ...

Sex differences in serum levels of 5α-androstane-3β, 17β-diol, and androstenediol in the young adults: A liquid chromatography-tandem mass spectrometry study.

PLoS ONE, 2021
Animal experiments have consistently shown that estrogen receptor β (ERβ)-selective ligands have antidepressant and anxiolytic effects. In humans, endogenous ligands for ERβ include 5α-androstane-3β, 17β-diol (3βAdiol) and androstenediol (Δ5-diol).

Hamilton $\ell$-Cycles in Randomly Perturbed Hypergraphs [PDF]

The Electronic Journal of Combinatorics, 2018
We prove that for integers $2 \leqslant \ell < k$ and a small constant $c$, if a $k$-uniform hypergraph with linear minimum codegree is randomly 'perturbed' by changing non-edges to edges independently at random with probability $p \geqslant O(n^{-(k-\ell)-c})$, then with high probability the resulting $k$-uniform hypergraph contains a Hamilton ...

Packing tight Hamilton cycles in 3-uniform hypergraphs

, 2010
Let H be a 3-uniform hypergraph with N vertices. A tight Hamilton cycle C \subset H is a collection of N edges for which there is an ordering of the vertices v_1, ..., v_N such that every triple of consecutive vertices {v_i, v_{i+1}, v_{i+2}} is an edge ...

Design of Sodium Chalcohalide Solid Electrolytes with Mixed Anions for All‐Solid‐State Sodium‐Ion Batteries

Advanced Functional Materials, EarlyView.
A novel family of sodium hafnium chalcohalide SSEs is designed with dual‐anion frameworks. Compared to the halide SSEs, the mixed anion chalcohalide framework exhibits a more compact morphology, improved thermal and mechanical properties, and enhanced electrochemical performance with different cathode materials.

Three infinite families of Hamilton-connected convex polytopes and their detour index

AIMS Mathematics
A path in a graph encompassing its whole vertex set is called Hamiltonian. Such a path with sharing the same initial and terminal vertices is called a Hamiltonian cycle. A graph comprising a Hamiltonian path (resp.

The Curriculum of the Jester: An Examination of Hamilton, An American Musical

Journal of Curriculum Theorizing, 2022
Relying on a curriculum theory and cultural studies lens, this paper examines the Broadway musical Hamilton and asks "What history is it teaching?".  Focusing on the cycle of cultural production, the paper further examines the lines of impact the musical
