Study of change in packed bed state of nano-structured FeTi hydrogen storage alloy

open access: yesNihon Kikai Gakkai ronbunshu, 2019
The volume of metal hydride packed bed changed by the influence of the expansion during hydrogen absorption and by the contraction during hydrogen desorption was measured by direct observation. The metal hydride used in the experiment are newly developed

Directional Lower Porosity [PDF]

open access: yesReal Analysis Exchange, 2014
We investigate differences between upper and lower porosity. In finite dimensional Banach spaces every upper porous set is directionally upper porous. We show the situation is very different for lower porous sets; there exists a lower porous set in the plane which is not even a countable union of directionally lower porous sets.

Hierarchical integration of porosity in shales [PDF]

open access: yesScientific Reports, 2018
AbstractPore characterization in shales is challenging owing to the wide range of pore sizes and types present. Haynesville-Bossier shale (USA) was sampled as a typical clay-bearing siliceous, organic-rich, gas-mature shale and characterized over pore diameters ranging 2 nm to 3000 nm.

Enhancing Corrosion Resistance and Mechanical Strength of 3D‐Printed Iron Polylactic Acid for Marine Applications via Laser Surface Texturing

open access: yesAdvanced Engineering Materials, EarlyView.
Laser surface texturing significantly improves the corrosion resistance and mechanical strength of 3D‐printed iron polylactic acid (Ir‐PLA) for marine applications. Optimal laser parameters reduce corrosion by 80% and enhance tensile strength by 25% and ductility by 15%.

Thermal performance investigation of a plate fin heat sink equipped with twisted tape and perforated twisted tape

open access: yesJournal of Thermal Science and Technology, 2021
The concept of heat transfer enhancement in a plate fin heat sink (PFHS) using twisted tape is presented. The airflow behavior in the flow channel and heat sink performance are investigated at the Reynolds numbers between 2000 and 5000.

Characterization and Analysis of Porosity and Pore Structures

open access: yes, 2015
Porosity plays a clearly important role in geology. It controls fluid storage in aquifers, oil and gas fields and geothermal systems, and the extent and connectivity of the pore structure control fluid flow and transport through geological formations, as

Cathode porosity is a missing key parameter to optimize lithium-sulfur battery energy density

open access: yesNature Communications, 2019
While high sulfur loading has been pursued as a key parameter to build realistic high-energy lithium-sulfur batteries, less attention has been paid to the cathode porosity, which is much higher in sulfur/carbon composite cathodes than in traditional ...
