Emerging materials for sample preparation

Journal of Separation Science, 2017
AbstractThis review provides an update on the implementation of emerging materials as sorbents for sample preparation in combination with chromatographic separation. We have focused on recent applications of metal–organic frameworks, layered double hydroxides, porous carbons obtained from polymers or biomass precursors, and silicates (clays and ...

Sampling of road surfacing materials

Journal of Applied Chemistry, 1970
AbstractThe meaning and purpose of sampling are discussed. Results are presented from a series of road trials on the sampling of asphalt mixtures to demonstrate the importance of bias and variability introduced into test measurements by sampling. Further variability is introduced by the reduction in size by quartering of gross samples to the size ...

Sampling Reactive Materials

2017
A reactive material is a material which can undergo further reaction either with itself or another material or compound under environmentally-mediated conditions. Examples of these types of reactions include polymerization, hydrolysis and oxidation. Since these reactions can occur in the workplace under ambient conditions or even on sampling media, the

Nested Sampling for Materials

2017
This chapter develops nested sampling into a powerful tool for the calculation of pressure-temperature phase diagrams, and demonstrates how it may be applied to single species and binary systems, including the Lennard-Jones system, a binary Lennard-Jones alloy, and an EAM model for Aluminium. A comparison to parallel tempering is also presented.
