Hamilton Cycles, Minimum Degree, and Bipartite Holes [PDF]

open access: yesJournal of Graph Theory, 2017
AbstractWe present a tight extremal threshold for the existence of Hamilton cycles in graphs with large minimum degree and without a large “bipartite hole” (two disjoint sets of vertices with no edges between them). This result extends Dirac's classical theorem, and is related to a theorem of Chvátal and Erdős.

Engineering a Sonotherapeutic RBC Membrane‐Derived Nanoparticle Platform for the Treatment of Liver Cancer

open access: yesAdvanced Functional Materials, EarlyView.
Herein, an RBC membrane‐derived nanoparticle (CMN‐ICG) is engineered to efficiently deliver a sonosensitizing agent, indocyanine green (ICG), for sonotherapy of hepatocellular carcinoma (HCC). CMN‐ICG exhibits excellent cytocompatibility, significantly enhances hepatocyte uptake, and produces excessive reactive oxygen species (ROS) upon ultrasound ...

Hamilton cycles in Euler tour graph

open access: yesJournal of Combinatorial Theory, Series B, 1986
The Euler tour graph of an Euler graph G denoted by \(E_ u(G)\) is the undirected simple graph defined as follows: The vertices of \(E_ u(G)\) are the Euler tours of G and two Euler tours E and F are adjacent in \(E_ u(G)\) if they can be transformed from each other by a K- transformation which was introduced by Kotzig in 1966.

Theory‐Guided Design of Non‐Precious Single‐Atom Catalyst for Electrocatalytic Chlorine Evolution

open access: yesAdvanced Functional Materials, EarlyView.
To overcome the reliance on noble metals for the chlorine evolution reaction (CER), we designed a non‐precious single‐atom catalyst (SAC), NiN3O–O. It achieves a low overpotential of 75 mV, 95.8% Cl2 selectivity, and outperforms commercial dimensionally stable anodes (DSAs).

Hamilton cycles and algorithms

open access: yes, 2022
We present three results in graph theory, united by the themes of Hamilton cycles and algorithms. A Hamilton cycle in a graph is a cycle that contains every vertex of the graph. The first result concerns path decompositions of digraphs, specifically an extension of a conjecture due to Alspach, Mason, and Pullman.

Mechanistic Insights into a Synergistic FeOx/Fe‐N4 System for Practical Nitrate Abatement with Value‐Added Ammonia Recovery

open access: yesAdvanced Functional Materials, EarlyView.
This work provides a novel interpretation of the nitrate reduction mechanism on iron oxides (FeOx) by employing constant‐potential density functional calculations and reports the design and synthesis of a robust and high‐performance Fe3O4/Fe‐N4‐C catalyst with remarkable Faradaic efficiency, current density, and stability under practical reaction ...

Femicomfort in the treatment of premenstrual syndromes: a double-blind, randomized and placebo controlled trial. [PDF]

open access: yesIranian Journal of Psychiatry, 2010
Objective: Premenstrual syndromes (PMS) affecting 20-40% of women of reproductive age. The aim of this double blind and placebo controlled trial was to investigate whether femicofort a supplement contains Vitamin B6, Vitamin E and evening primrose oil ...

Interparticle Bonding of Cu Powder under Repetitive Unidirectional Friction

open access: yesTribology Online, 2018
Unidirectional friction experiments on uniaxially compressed pure Cu powder were performed to clarify how the solid-phase interparticle bonding proceeds during a powder molding method by applying biaxial force, termed as a compression shearing method at ...

Spin‐Dependent Generation of Surface‐Bound Radicals Toward Selective and Long‐Lasting Water Purification

open access: yesAdvanced Functional Materials, EarlyView.
This study develops a novel atomic engineering strategy to fine‐tune the spin state of α‐Fe2O3 catalysts toward a medium‐spin state, thereby modulating peroxymonosulfate activation and selectively yielding surface‐bound radicals. Compared with free radicals, surface‐bound radicals exhibit moderated oxidation potential, extended lifespan, surface ...
