HPLC Column

The surface area of the particle is inversely proportional to the pore diameter; therefore, a 3 mm particle with a 120 nm pore diameter will have more than twice the surface area of a 3µm particle with a 300 nm pore diameter. There are a number of pore diameters used by manufacturers to control retention.

It is the pore diameter that is being sought.

Unveiling the relationship between MOF porosity, particle size…

This effect was clear in the mean pore size determination as clarified in Fig. 8 d. The mean pore size was slightly improving from 26.3 nm to 31.8 nm by increasing the porosity from M−0 to M−4. The improved mean pore size was attributed to the same reasons of improved porosity. 3.4. Zinc release profile

Study on the influence of microcracks of coarse aggregate …

The relationship between the microcracks of a single particle and the crushing strength was studied by virtual experiments. The three-dimensional profile of a single particle was obtained by CT-scanning technology. The particle bonding model is used to fill the three-dimensional contour to construct virtual particles, and the virtual crushing experiment is …

Relationship between breaking force and pore structure of …

The aim of this study was to determine the relationship between the breaking force of lactose, glucose and mannitol tablets and the pore structure characterised by numeric porosity parameters: total pore volume, total pore surface area, mean pore diameter, median pore diameter and volume-size distribution of pores, obtained by mercury porosimetry.

DEM study on the effect of pore characteristic on single …

The particle crushing strength decreases with the increase of porosity and fractal dimension of pore distribution. Further discussion confirmed that the particle crushing strength …

The relationship between pore structure and strength of …

The reason for the larger porosity of A100 compared to A0 at 20 °C is that the particle size of AS is smaller than that of RS, and the particle size is concentrated in the range of 0.1–0.3 mm. A large amount of AS replaced RS, resulting in a lack of aggregate grading.

Fractal behavior of particle-size distribution during particle crushing

The fractal model based on the correlation between the number, weight, and particle size of disintegrated particles was established to describe the disintegration process.

Effects of particle size on the particle breakage of …

In addition, the curve slope of the particle size with 5.00 ∼ 2.00 mm is slower, while the curve slope of the particle size with 0.50 ∼ 0.25 mm is greater, implying that the correlation between the volume deformation and particle breakage degree of coarse particles is higher than that of fine particles.

Influence of the particle morphology and internal porosity

As can be seen, the distribution of natural coral sand's particle sizes falls primarily between 0.5 and 5 mm, with the particle size content making up >76% of the entire sample. In light of this, the research work's particle size. Effect of mineral composition and particle size on roundness. Particle roundness degree is referred to as roundness.

Fine control of NaCl crystal size and particle size in

Fig. 4 a shows a narrow pore size distribution between ~ 0.11 and ~ 0.05 µm. ... Fig. 11 a shows a relationship between NaCl particle size and water flux, where a fine control in average particle size is demonstrated for the membrane carbonised at 750 °C. As this membrane delivered the highest water flux, it formed the smaller particle sizes ...

Influence of particle size on pore structure and multifractal

We reveal a negative power function relationship among particle size and pore volume, and SSA, indicating that crushing opens up more pores that were initially closed.

Particle size effect on pore structure characteristics of lignite

For decreasing lignite particle sizes, the change in pore specific surface area and pore volume can be calculated using the formula: Δ YM1-YMn, where YM1 represents the subsample with the largest particle size, YMn refers to subsamples where the particle size decreases sequentially (YM3, YM4, YM5, YM6, YM7, and YM8, respectively), and Δ ...

Fractal Analysis of Particle Size and Morphology in Single-Particle …

The relationship between 3D fractal dimensions and particle size, particle crushing strength, and morphology is meticulously investigated. Furthermore, the implications of these relationships on the particle breakage processes are thoroughly discussed, shedding light on the underlying mechanisms that govern particle breakage.

Particle size distribution of cement and concrete

Particle size distribution (PSD) is an essential property of cement. The only standard method to measure the PSD of cement, namely ASTM C115 is limited in scope; this standard describes a method ...

A compression line for soils with evolving particle and pore size

A good match between theoretical and experimental particle size distribution curves was only possible for data points having e values less than 0·26; this implies that e = 0·26 represents an (approximate) limit below which the amount of crushing becomes significant enough for the fractal dimensions and other parameters to be held constant.

Experimental Study of the Crushing Characteristics of Single Particle …

Since t 10 refers to the cumulative yield under the screen of the impact crushing product whose particle size is less than 1/10 of the initial particle size, in order to facilitate the acquisition of t 10 value from the crushed product, the horizontal coordinate in Figs. 7–9 is represented by the relative size (x i /x 0), that is, the ratio ...

Relationship Between Pore Size and Filtration Efficiency in …
