Convective shutdown in a porous medium at high Rayleigh number

open access: yes
Convection in a closed domain driven by a dense buoyancy source along the upper boundary soon starts to wane owing to the increase of the average interior density.

Preparation of N-Doped Layered Porous Carbon and Its Capacitive Deionization Performance

open access: yes, 2023
In this study, N-doped layered porous carbon prepared by the high-temperature solid-state method is used as electrode material. Nano calcium carbonate (CaCO3) (40 nm diameter) is used as the hard template, sucrose (C12H22O11) as the carbon source, and ...

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

open access: yesAdvanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

A solid with a hierarchical tetramodal micro-meso-macro pore size distribution

open access: yes, 2013
Porous solids have an important role in addressing some of the major energy-related problems facing society. Here we describe a porous solid, alpha-MnO2, with a hierarchical tetramodal pore size distribution spanning the micro-, meso-and macro pore range,

Gas hydrate growth and dissociation in narrow pore networks: capillary inhibition and hysteresis phenomena [PDF]

open access: yes, 2009
Marine sediments hosting gas hydrates are commonly fine-grained (silts, muds, clays) with very narrow mean pore diameters (0.1 mm). This has led to speculation that capillary phenomena could play an important role in controlling hydrate distribution in
