Optical properties of zigzag nickel nanostructures obtained at different deposition angles [PDF]

open access: yesScience of Sintering, 2021
In this study, nickel (Ni) thin films were deposited at two different angles (65o and 85o) using Glancing Angle Deposition technique, to the thicknesses of 60 - 290 nm.

Porosity in minerals

open access: yesAIMS Materials Science, 2022
Minerals typically form porous assemblies with porosity extending from a few percent to ca. 35% in porous sandstones, and over 50% in tuff, clays, and tuff. While transport of gases and liquids are widely researched in these materials, much less is known

A critical review on the effects of process-induced porosity on the mechanical properties of alloys fabricated by laser powder bed fusion

open access: yesJournal of Materials Science, 2022
Laser powder bed fusion (LPBF) is an emerging additive manufacturing technique that is currently adopted by a number of industries for its ability to directly fabricate complex near-net-shaped components with minimal material wastage.

Medical Applications of Porous Biomaterials: Features of Porosity and Tissue‐Specific Implications for Biocompatibility

open access: yesAdvanced Healthcare Materials, 2022
Porosity is an important material feature commonly employed in implants and tissue scaffolds. The presence of material voids permits the infiltration of cells, mechanical compliance, and outward diffusion of pharmaceutical agents.

Variation of Open-Pit Waste Dump Specimens Under Effective Pressure Influence

open access: yesFrontiers in Earth Science, 2021
The waste dump is a giant artificial loose pile body composed of fine, medium, and coarse particle sizes. Rising incidents of landslides caused by overburden pressure and effective pressure are of increasing concern in the open-pit waste dump and, if not

A modified pulse‐decay approach to simultaneously measure permeability and porosity of tight rocks

open access: yesEnergy Science & Engineering, 2021
Permeability and porosity are the two most important parameters of rocks for the evaluation and exploitation of oil/gas reservoirs. In this study, a modified pulse‐decay method has been developed to measure both permeability and porosity simultaneously ...

Quantification of bound water content, interstitial porosity and fracture porosity in the sediments entering the North Sumatra subduction zone from Cation Exchange Capacity and IODP Expedition 362 resistivity data [PDF]

open access: yesMarine and Petroleum Geology, Elsevier, 2020, 111, pp.156-165, 2020
In this study, we investigate porosity evolution through the sedimentary input section of the North Sumatra Subduction zone by quantifying interstitial porosity, bound water content and fracture porosity based on IODP Expedition 362 data and post-cruise chemical analyses.
