Electrochemical methods for restructuring of metal surfaces: mechanisms and strategies for tailoring free-standing electrocatalysts

Mohamed M. Elnagar · Ludwig A. Kibler · Timo Jacob

Electrocatalysis is driven by the chemical nature of electrodes and their surfaces. Furthermore, the electrocatalytic activity and selectivity critically depend on the atomic surface arrangement of electrodes, characterized by facets and their crystallographic orientation, surface steps, and defects, i.e., the electrod...

Viscous pressureless flows with free boundary in one space dimension: The constant viscosity case

Xin Liu

We establish the global well-posedness of the free boundary problem of the viscous pressureless and almost pressureless heat conductive flows in one space dimension. In both cases, arbitrarily large but smooth initial data is considered, and the evolving fluid domains remain bounded for all time. In the viscous pressur...

Compact harmonic RCD (K, N) spaces are harmonic manifolds

Zhangkai Huang

In this paper, we study harmonic RCD$(K,N)$ spaces as the counterpart of harmonic Riemannian manifolds with Ricci curvature bounded from below. We prove that a compact RCD$(K,N)$ space is isometric to a smooth closed Riemannian manifold if it satisfies either of the following harmonicity conditions:(1) the heat kernel...

Spectral properties of surface-localized transmission eigenmodes and applications to inverse scattering problems

Jiang, Yan · Liu, Hongyu · Zhang, Kai · Zheng, Haoran

This paper investigates a distinctive spectral pattern exhibited by transmission eigenfunctions in wave scattering theory. Building upon the discovery in [7, 8] that these eigenfunctions localize near the domain boundary, we derive sharp spectral density estimates--establishing both lower and upper bounds--to demonstra...

Predicting wicking dynamics of Newtonian liquid droplet in paper channels

Anuragmani, Tripathi · Rishabh, More · Simon, Corrie · Gil, Garnier

Capillary-driven wicking in porous substrates is commonly described by models assuming an infinite liquid reservoir, which is not a valid assumption for point-of-care applications using finite droplets. In addition, wicking depends on multiple factors such as paper microstructure, fluid properties, and fabrication meth...

Evolution of organic matter with subcritical water during the formation of icy moons.

Gabriel TOBIE · Léo POCHAT · Anna PAKHOMOVA · Michael HANFLAND · y 3 más

Recent models and observations suggest that organic matter (OM) is a major compound of the refractory cores of the icy moons of the solar system. This OM would have interacted with large amounts of water only during the accretion and differentiation of these bodies (before/during the formation of the refractory core)....

Liouville Type Results for Quasilinear Elliptic Inequalities Involving Gradient Terms on Weighted Graphs

Duong, Anh Tuan · Liu, Yao · Minh, Nguyên Công · Quyet, Dao Trong · y 1 más

In this paper, we study the following quasi-linear elliptic inequality $Δ_m u +u^p |\nabla u|^q \leqslant 0$ on weighted graphs, where $(m,p,q)\in (1,\infty)\times\mathbb{R}\times\mathbb{R}$. According to the ranges of parameters $(m, p, q)$, we establish the non-existence of nontrivial positive solutions under the cor...

Elemental distribution and speciation of Sr in bones to improve growth model in palaeontology

Romain AMIOT · Hugo Mathias BERT · Jean GOEDERT · Léa DE BRITO · y 1 más

Almost all skeletal tissues record visible marks such as Lines of Arrested Growth (LAGs) that form annually during the unfavourable season. The identification of LAGs serves in palaeontology to calculate individual ages and to model the growth of organisms. However, sometimes bone growth slows down without ceasing, whi...

Spectral constants for the quantum annulus

Pal, Sourav · Pascoe, James E. · Tomar, Nitin

We find several new estimates for the spectral constants $K(\mathbb A_r)$ for which a closed annulus $\overline{\mathbb A}_r$ or closed polyannulus $\overline{\mathbb A}^n_r$ is a $K$-spectral set for operators in the quantum annulus $\mathbb Q \mathbb A_r$. We give two alternative proofs to an existing estimate of spe...

Experimental investigation of inlet subcooling effects on flow boiling in an open microchannel under hydrostatic inlet-head control

Jaume Camarasa · Montse Vilarrubí · Pol Rosell · Alicia Crespo · y 2 más

Open microchannels are a promising configuration for flow boiling because the top gap facilitates vapor evacuation and liquid replenishment, thereby improving thermal performance and moderating flow instabilities. However, their behavior under different inlet subcooling conditions remains insufficiently understood unde...
