6.3.1 IntroductionCoal is a dual-porosity organic rock with complicated pore structure from nano- to microscales. The International Union of Pure and Applied Chemistry (IUPAC) has classified the pores into three categories: micropores (<2nm...
cell ingrowth or physicochemical bonding. Other drivers for the development of a permanent porous biomaterial include closer structural replication of the host tissue. The material properties of solid PEEK are already considered useful to produce flexible implants, and the introduction of porosity may pro...
nuclear magnetic resonance and so on.It is showed that the reservoir space of studied area is dominated by solution-type secondary porosity.Intercrystalline pore is relatively more and residual intergranular pore is relatively small.Intercrystalline pore may be good reservoir sites owing to the ...
while resistivity logging has a general response to fractures; In layers with more developed fractures, natural gamma values are mostly higher than 40API, rock volume density is less than 2.8 g/cm3, neutron porosity is greater than 12.5%, and acoustic time difference is greater than 160 μ s...
A fine pore-preserved deep neural network for porosity analytics of a high burnup U-10Zr metallic fuel Article Open access 14 December 2023 Introduction Next-generation advanced nuclear reactors with improved safety and economics are the future of nuclear energy for the United States and worldwide...
Overall, the object is rather heterogeneous with a high amount of porosity (Fig. 4a). Numerous metal prills are distributed throughout the slag, and most of them are smaller than 10 μm in diameter. A small fraction ranges up to 100 μm, and only some of the prills are larger than 1...
[247]. Fluctuations in MC in coated wood cladding systems are influenced by the film thickness, porosity, durability and colour of the coating systems employed [248]. According to EN 971–1 [249] (superseded by ISO 4618 [250]) a coating is defined as: ‘a product, in liquid, in paste...
Introduction Biomass-derived activated carbon can be the electrode material for high performance EDLCs, owing to its high surface area, porosity, and excel... Toshiki Tsubota,Anh Duy Khuong,Daiki Morioka - IOP Publishing Ltd 被引量: 0发表: 2024年 ...
the effective porosity becomes zero, hence, the bearing ratio is assumed to be 100%. Of course, cutting through the grains would reveal pores inside the structure. However, those pores are not considered to be part of the effective porosity of the surface. Clearly, effective porosity of the ...
Introduction Porous organic materials have attracted wide interest due to their distinguished advantages, such as high surface area, tuneable porosity, and easy processability.1,2 They combine the advantages of both porous frameworks and polymers and have the following unique properties for high-performan...
