Mass Spectrometry: Overview

Mass Spectrometry: Overview

Mass spectrometry is an analytical technique used to determine the molecular mass and molecular formula of a compound. The basic principle of mass spectrometry is to generate ions from the analyte molecule and measure these ion abundances against their molecular mass. One common type of ionization, known as electron ionization or EI, bombards the analyte molecules in the gas phase with high-energy electron beams. The electron beams displace an electron from the molecule and leave behind a...

Maxwell-Boltzmann Distribution: Problem Solving

Maxwell-Boltzmann Distribution: Problem Solving

Individual molecules in a gas move in random directions, but a gas containing numerous molecules has a predictable distribution of molecular speeds, which is known as the Maxwell-Boltzmann distribution, f(v).
This distribution function f(v) is defined by saying that the expected number N (v1,v2) of particles with speeds between v1 and v2 is given by

Mass Spectrometry: Complex Analysis

Mass Spectrometry: Complex Analysis

Mass spectrometry is an important technique for the identification of pure compounds. However, it has some limitations for the analysis of complex mixtures, often due to excessive fragmentation making the spectrum too complicated to decipher. Mass spectrometry can be combined with suitable separation methods in sequence, forming hyphenated methods, which are useful in the analysis of complex mixtures.
GC–MS is a powerful hyphenated method commonly used in forensics and environmental...

Porosity and Absorption of Aggregate

Porosity and Absorption of Aggregate

Aggregates contain pores of varying sizes; while some are completely enclosed within the particles, others open onto the surface, allowing water to penetrate. The porosity of aggregates is a major factor contributing to the overall porosity of concrete, given that aggregates constitute about three-quarters of concrete's volume.
When all pores in an aggregate are filled with water, the aggregate is considered saturated and surface-dry. If left in dry air, water will evaporate until the aggregate...

Pore Size Distribution

Pore Size Distribution

In concrete, the pore size distribution significantly influences the material's properties. Capillary pores, markedly larger than gel pores, form a vast network within partially hydrated cement paste, reducing the concrete's strength and increasing its permeability. This heightened permeability leads to a greater risk of damage from environmental factors like freeze-thaw cycles and chemical attacks, with the extent of vulnerability also being tied to the water-to-cement ratio.
Adequate...

Geology

Background:

Small-angle scattering (SAS) is crucial for characterizing porous media.
Existing tools often lack comprehensive pore analysis capabilities, especially for sedimentary rocks.

Purpose of the Study:

To introduce MATSAS, a novel MATLAB program for advanced SAS data analysis.
To provide a comprehensive suite of pore characterization tools for sedimentary rocks.

Main Methods:

MATSAS imports and processes SAS data from various sources (.xls(x), .csv).
It utilizes the polydisperse spherical (PDSP) model for structural analysis.
The program calculates specific surface area, porosity, pore size distributions, and fractal dimensions.

Main Results:

MATSAS enables rapid, simultaneous analysis of multiple samples.
It offers a full suite of pore characterizations, a first for sedimentary rocks.
Results are exported in .xlsx and .csv formats for easy data sharing.

Conclusions:

MATSAS is a powerful, open-source tool for SAS data analysis in porous media.
It significantly advances the characterization of sedimentary rock pore structures.
