Tissue engineering scaffolds provide temporary mechanical support for tissue regeneration. To regenerate tissues more efficiently, an ideal structure of scaffolds should have appropriate porosity and pore structure. In this paper, we generate the Schwarz primitive P surface with various volume fractions using a phase-field model. The phase-field model enables us to design various surface-to-vol...

Porosity is one of the fundamental petrophysical properties that should be evaluated for hydrocarbon bearing reservoirs. It is a vital factor in precise understanding of reservoir quality in a hydrocarbon field. Log data are exceedingly crucial information in petroleum industries, for many of hydrocarbon parameters are obtained by virtue of petrophysical data. There are three main petrophysical...

A detailed study on the anode structure of solid oxide fuel cell (SOFC) is very crucial in developing high performance power generating devices, given how porous electrodes are known to provide a number of active sites for reaction, consequently accelerate fuel conversion. This present study investigates the feasibility of pore former addition to nickel oxideyttria stabilized zirconia (NiO-YSZ)...

An ideal scaffold for bone regeneration will provide adequate mechanical support and eventually degrade after bone healing without causing harm to the body. Chitosan, mixed with carboxymethyl chitosan, creates a scaffold with high porosity, but low mechanical strength. Therefore, the objective of this research is to develop biofunctional chitosan based scaffolds for possible application in bone...

The most commonly used solid oxide fuel cell (SOFC) anode material is a two phase nickel and yttria stabilized zirconia (Ni/YSZ) cermet. And the mechanical stability of anode support layer, in anode-supported electrolyte designs, is very important for large scale applications. During the assembly of stack and normal operation, the cermet anode should withstand enough mechanical loading to preve...

Tissue scaffolds provide structural support while facilitating tissue growth, but are challenging to design due to diverse property trade-offs. Here, a computational approach was developed for modeling scaffolds with lattice structures of eight different topologies and assessing properties relevant to bone tissue engineering applications. Evaluated properties include porosity, pore size, surfac...

The porosity of a zone can be estimated either from a single “porosity log” (sonic, density, neutron, or magnetic resonance log) or a combination of porosity logs, in order to correct for variable lithology effects in complex reservoirs. In the carbonates, mineral mixtures are primarily drawn from calcite, dolomite, and quartz (either as sand grains or as chert); anhydrite and gypsum may also o...

In industry, the porosity of petrochemical reservoirs is measured frequently by coring and is an important property when trying to determine if a site is appropriate for drilling. Porosity can also be used in waste water treatment in order to determine if a material is ideal for water purification in industrial or residential applications. The purpose of this experiment was to simulate a oil re...
