A Local Gauge-Covariant Formulation of Classical Dynamics
Gunjan Auti, Hirofumi Daiguji, Gouhei Tanaka
Classical dynamical laws are conventionally formulated as closed evolution equations defined on fixed geometric backgrounds and a global time parameter. We develop a formulation in…
Structures of iron and cobalt bimetallic clusters for optimized chemical vapor deposition growth of single-walled carbon nanotubes
Qingmei Hu, Daniel Hedman, Ya Feng +17
We investigate iron-cobalt (Fe-Co) alloys as a representative high-performance catalyst system for SWCNT growth in a systematic manner by combining chemical vapor deposition (CVD)…
Analysis of Fe and Co binary catalysts in chemical vapor deposition growth of single-walled carbon nanotubes
Qingmei Hu, Ya Feng, Wanyu Dai +17
Metal catalysts play a pivotal role in the growth of single-walled carbon nanotubes (SWCNTs), with binary metallic catalysts emerging as an efficient SWCNT synthesis strategy. Amon…
Hebbian Physics Networks: A Self-Organizing Computational Architecture Based on Local Physical Laws
Gunjan Auti, Hirofumi Daiguji, Gouhei Tanaka
Physical transport processes organize through local interactions that redistribute imbalance while preserving conservation. Classical solvers enforce this organization by applying…
Statistical modeling of equilibrium phase transition in confined fluids
Gunjan Auti, Soumyadeep Paul, Wei-Lun Hsu +3
The phase transition of confined fluids in mesoporous materials deviates from that of bulk fluids due to the interactions with the surrounding heterogeneous structure. For example,…
Thermodynamic Bifurcations of Boiling in Solid-State Nanopores
Soumyadeep Paul, Yusuke Ito, Wei-Lun Hsu +1
Boiling heat transfer is the basis of many commonly used cooling techniques. In cooling of electronic devices, for example, it is desirable to further miniaturize heat exchangers t…
Boiling in Nanopores through Localized Joule Heating: Transition between Nucleate and Film Boiling
Soumyadeep Paul, Wei-Lun Hsu, Yusuke Ito +1
The transition from nucleate to film boiling on micro/nano textured surfaces is of crucial importance in a number of practical applications, where it needs to be avoided to enable…
A theoretical understanding of ionic current through a nanochannel driven by a viscosity gradient
Amer Alizadeh, Hirofumi Daiguji, Anne M. Benneker
It has been recently shown that a viscosity gradient could drive electrical current through a negatively charged nanochannel (Wiener and Stein, arXiv: 1807.09106). To understand th…
Transport-Induced-Charge Electroosmosis
Wei-Lun Hsu, Zhixuan Wang, Hirofumi Daiguji
We report theoretical analysis of transport-induced-charge electroosmosis (TICEO) in a nanopore due to the presence of a local electric field and a conductivity gradient. TICEO sha…
Evaluation of gas permeability in porous separators for polymer electrolyte fuel cells: CFD simulation based on micro X-ray computed tomography images
Soichiro Shimotori, Toshihiro Kaneko, Yuta Yoshimoto +4
Pore structures and gas transport properties in porous separators for polymer electrolyte fuel cells are evaluated both experimentally and through simulations. In the experiments,…
Single-Bubble Dynamics in Nanopores: Transition Between Homogeneous and Heterogeneous Nucleation
Soumyadeep Paul, Wei-Lun Hsu, Mirco Magnini +4
When applying a voltage bias across a thin nanopore, localized Joule heating can lead to single bubble nucleation, offering a unique platform for studying nanoscale bubble behavior…
Viscoelectric Effects in Nanochannel Electrokinetics
Wei-Lun Hsu, Dalton J. E. Harvie, Malcolm R. Davidson +3
Electrokinetic transport behavior in nanochannels is different to that in larger sized channels. Specifically, molecular dynamics (MD) simulations in nanochannels have demonstrated…
