“…Throughout the described examples, high importance is placed on the application of SANS alongside other scattering techniques. This can be used to increase the range of sizes detected, using USANS, 11,12,84,115 or to provide a different contrast, using SAXS, 44,45,55,56,114,118 from which material composition can additionally be estimated using ACV. 133 Additionally, the importance of evidence from microscopy techniques cannot be ignored as this provides critical information that can be fed into the SANS data modelling to increase accuracy.…”

[84][85][86][92][93][94][95] The ability to generate such detail is clearly of benefit to the identification of structureproperty relationships and SANS has a crucial role to play, particularly in determining the statistically significant structural parameters.…”

Recent improvements in beam-line accessibility and technology have led to small-angle neutron scattering (SANS) becoming more frequently applied to materials problems. SANS has been used to study the assembly, dispersion, alignment and mixing of nanoscale condensed matter, as well as to characterise the internal structure of organic thin films, porous structures and inclusions within steel.Using time-resolved SANS, growth mechanisms in materials systems and soft matter phase transitions can also be explored. This review is intended for newcomers to SANS as well as experts. Therefore, the basic knowledge required for its use is first summarised. After this introduction, various examples are given of the types of soft and hard matter that have been studied by SANS. The information that can be extracted from the data is highlighted, alongside the methods used to obtain it. In addition to presenting the findings, explanations are provided on how the SANS measurements were optimised, such as the use of contrast variation to highlight specific parts of a structure. Emphasis is placed on the use of complementary techniques to improve data quality (e.g. using other scattering methods) and the accuracy of data analysis (e.g. using microscopy to separately determine shape and size). This is done with a view to providing guidance on how best to design and analyse future SANS measurements on materials not listed below.

“…However, for most geological applications where the concentration of scatterers in a given rock volume is of interest (i.e. the pore fraction or absolute pore volume distribution), then the data must fi rst be corrected for various effects and normalized to an absolute intensity scale (units of cm -1 , Wignall and Bates 1987;Russell et al 1988;Heenan et al 1997;Glinka et al 1998;Orthaber et al 2000;Hu et al 2011b;Wignall et al 2012). This can either be done by referencing the results to a precalibrated sample or relative to the intensity of the direct beam.…”
