Bridging Theory and Experiment: Machine Learning Potential‐Driven Insights into pH‐Dependent CO₂ Reduction on Sn‐Based Catalysts

open access: yesAdvanced Functional Materials, EarlyView.
Machine learning potential (MLP) enables large‐scale molecular dynamics (MD) simulations, uncovering dynamic surface reconstruction of SnO₂ and SnS₂ under CO₂ reduction reaction condition. The negative dipole moments upon *OCHO adsorption are the primary factors driving the leftward shift of the volcano plot.

A Triple of Heavy Subgraphs Ensuring Pancyclicity of 2-Connected Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2017
A graph G on n vertices is said to be pancyclic if it contains cycles of all lengths k for k ∈ {3, . . . , n}. A vertex v ∈ V (G) is called super-heavy if the number of its neighbours in G is at least (n+1)/2.

Have Business Cycles Become More Synchronous After NAFTA?

open access: yesAmerican Business Review, 2021
Trade agreements do not necessitate business cycle comovement. Focusing on NAFTA, we investigate whether business cycles in Canada, Mexico, and the US have become more synchronous after the landmark trade agreement came into effect in 1994.

Accelerated Kinetics of Desolvation and Redox Transformation Enabled by MOF Sieving for High‐Loading Mg‐S Battery

open access: yesAdvanced Functional Materials, EarlyView.
A strategy of sieving catalysis based on the MIL‐101(Cr) with multistage pore structure and Lewis acid sites has been proposed as the catalyst to accelerate the kinetics of desolvation and redox conversion of sulfur species, achieving high performance Mg‐S batteries.

Highly Active Air Electrode with Enhanced Proton Conduction via Isovalent Doping in a Layered Perovskite for Reversible Protonic Ceramic Cells

open access: yesAdvanced Functional Materials, EarlyView.
A Ni‐doped PBSCN20 air electrode is proposed as a promising air electrode material for reversible protonic ceramic cells. An isovalent doping significantly facilitates oxygen vacancy formation and proton uptake while simultaneously reducing the energy barrier for proton migration.

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

open access: yesAdvanced 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

On hamiltonicity of uniform random intersection graphs

open access: yesLietuvos Matematikos Rinkinys, 2010
We give a sufficient condition for the hamiltonicity of the uniform random intersection graph G{n,m,d}. It is a graph on n vertices, where each vertex is assigned d keys drawn independently at random from a given set of m keys, and where any two vertices
