Modelling of Effective Permeability Coefficient Caused by the Formation of CO2 Hydrate in Sand Layer Using Pore-Scale Numerical Simulations

open access: yesJournal of MMIJ, 2021
Carbon dioxide capture and storage is an efficient technology to reduce CO2. Among CO2 storage methods, storage in the form of gas hydrate is thought to be promising for increasing the volume capacity of storable CO2.

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Thickness Dependence of Switching Behavior in Ferroelectric BiFeO3 Thin Films: A Phase-Field Simulation

open access: yesApplied Sciences, 2017
A phase-field approach to the analysis of the thickness effects in electric-field-induced domain switching in BiFeO3 thin films has been formulated. Time evolutions of domain switching percentage for films with different thicknesses were explored to ...

Numerical simulation on the freezing of deposited or impinged water droplets on a cold surface

open access: yesJournal of Thermal Science and Technology, 2021
The freezing of water droplets deposited or impinged on cold surfaces causes many problems in traffic lights, power transmission wires and heat exchangers. Thus, the suppression of the freezing of these droplets is very important.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Phase-field topology optimization model that removes the curvature effects

open access: yesMechanical Engineering Journal, 2017
The conventional phase-field topology optimization (PFTO) models minimize not only the objective function but also the interface energy. In the present study, a new PFTO model, which minimizes only the objective function, is developed by removing the ...

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

A phase‐field method for modeling cracks with frictional contact [PDF]

open access: yesInternational Journal for Numerical Methods in Engineering, 2019
SummaryWe introduce a phase‐field method for continuous modeling of cracks with frictional contacts. Compared with standard discrete methods for frictional contacts, the phase‐field method has two attractive features: (i) it can represent arbitrary crack geometry without an explicit function or basis enrichment, and (ii) it does not require an ...

Numerical Simulation of Dynamic Capillary Rise with Cryogenic Fluids under Microgravity

open access: yesZhileng xuebao, 2023
Spacecraft use surface tension to transport liquid fuel and continuously provide gas-free propellants to engines. To ensure the normal operation of spacecraft, it is important to study the capillary flow behavior of liquid propellants. In this study, the
