Gas sorption properties of amino-functionalized metal-organic frameworks

Pascal D C DIETZEL · Chloe FULLER · Susan SEN · Kristine Marie HALVORSEN · y 1 más

Surface-grafted amino groups are implicated in enhanced interaction with carbon dioxide. This can be exploited in more efficient carbon capture processes. The purpose of this experiment is to elucidate the structural response of metal-organic frameworks constructed from organic linkers carrying amino- and diamino-group...

Can explicit subgrid models enhance implicit LES simulations? A very high-order solver perspective

Gonzalo Rubio · Gerasimos Ntoukas · Miguel Chávez-Módena · Oscar Mariño · y 4 más

High-order discontinuous Galerkin (DG) methods offer excellent accuracy for turbulent-flow simulations and are increasingly attractive on GPU-oriented architectures, where high polynomial orders can improve arithmetic intensity. However, very high-order under-resolved simulations remain sensitive to the balance between...

Composition-tunable H-PC/LPC discoidal lipid assemblies: molecular packing, nanoscale organization, and permeation behavior

Toshihiro, Mori · Nanami, Kiriyama · Mayuko, Miyanishi · Katsunori, Yoshida · y 1 más

Discoidal membrane-like lipid assemblies provide a useful framework for linking lipid composition to nanoscale organization and interfacial transport, but practical solvent-avoiding routes from formulation-compatible phospholipids remain limited. Here, hydrogenated phosphatidylcholine (H-PC)/lysophosphatidylcholine (LP...

Multivariable Wold-type decomposition and analytic models for a class of left-inverse commuting pairs

Bhattacharjee, Monojit · Gupta, Rajeev · Venugopal, Vidhya

This work establishes a multivariable Wold-type decomposition for left-inverse commuting $n$-tuples of bounded operators, built on the hypothesis that each component admits a Wold-type decomposition. For pairs of operators, we obtain a complete analytic model: every left-inverse commuting analytic toral $2$-isometric p...

Low regularity Sobolev well-posedness for Vlasov–Poisson

Jeong, In-Jee · Tae, Sangwook

We consider the Vlasov--Poisson equation on $\mathbb{R}^n \times \mathbb{R}^n$ with $n \ge 3$. We prove local well-posedness in $H^{s}(\mathbb{R}^n \times \mathbb{R}^n)$ with $s> n/2-1/4$, for initial distribution $f_{0} \in H^{s}(\mathbb{R}^n \times \mathbb{R}^n)$ having compact support in $v$. In particular, data not...

Following the proton: My journey through bioenergetics

Joachim, Heberle

As devised by Peter Mitchell's chemiosmosis, protons are actively translocated across a biological membrane, creating the proton motive force, which stores free energy in the form of an electrochemical gradient. Here, protons (H+ ions) are not merely participants but the core mediators of energy transduction: they stor...

The new clinical reality—mixed reality, augmented reality, virtual reality, 3D modeling, 3D printing, artificial intelligence: transformative technologies in medical practice in cardiology

H3PC: Hypersonic, high-order, high-performance code with adaptive mesh refinement and real chemistry

Ahmad Peyvan · Khemraj Shukla · George Em Karniadakis

We have developed a hypersonic high-order, high-performance code (H$^3$PC) utilizing the ``Trixi.jl" framework in order to simulate both non-reactive and chemically reactive compressible Euler and Navier-Stokes equations for complex three-dimensional geometries. H$^3$PC is parallel on CPU platforms and can perform exas...

Structure and dynamics of colloidal suspensions

Narayanan THEYENCHERI · Michael SZTUCKI · Avik DAS · Gouranga MANNA

The interactions and dynamics of different colloidal particles will be studied.

An Entropy-Stable Oscillation-Eliminating DGSEM for the Euler equations on curvilinear meshes

Jielin Yang · Guosheng Fu

We develop an entropy-stable high-order numerical method for the two-dimensional compressible Euler equations on general curvilinear meshes. The proposed approach is based on a nodal discontinuous Galerkin spectral element method (DGSEM) that satisfies the summation-by-parts (SBP) property. At the semidiscrete level, e...
