“…Figure 21 shows a single snapshot of this recorded movie which allowed us for the first time to watch the engine work "from the inside" in real time. 147 In addition to the above mentioned industrial applications, neutron testing and imaging techniques are routinely used in examining geological and construction materials, 145,148,149 archeology, 150 metallurgy, 151 as well as water flow and diffusion in soil 142 and engineered porous materials. 152 One of the most recent applications of NTR is in situ measurements of the water transport in operating proton exchange membrane fuel cells.…”

Modern materials science and engineering relies increasingly on detailed knowledge of the structure and interactions in "soft" and "hard" materials, but there have been surprisingly few microscopic techniques for probing the structures of bulk samples of these substances. Small-angle neutron scattering ͑SANS͒ was first recognized in Europe as a major technique for this purpose and, over the past several decades, has been a growth area in both academic and industrial materials research to provide structural information on length scales ϳ10-1000 Å ͑or 1-100 nm͒. The technique of ultrahigh resolution small-angle neutron scattering ͑USANS͒ raises the upper resolution limit for structural studies by more than two orders of magnitude and ͑up to ϳ30 m͒ and hence overlaps with light scattering and microscopy. This review illustrates the ongoing vitality of SANS and USANS in materials research via a range of current practical applications from both soft and hard matter nanostructured systems.

“…Neutron imaging [1][2][3][4] and neutron diffraction [5][6][7] have been demonstrated to be important tools in the study of archaeological artefacts because they allow morphological and compositional analysis of the objects in a completely nondestructive way. The combination of imaging and compositional analyses using neutrons, as well as complementary techniques, have been exploited in a few studies.…”

Here, an innovative non-invasive multi-analytical approach for the archaeometallurgical characterisation of ancient bronze artefacts using high resolution neutron tomography, time of flight neutron diffraction, and laser induced plasma spectroscopy has been investigated. We show its effectiveness through an example application aimed at describing the crafting processes, characterising the alloy compositions and deterioration phenomenologies of three small bronze figurines from the antiquarian collection of the Egyptian Museum of Florence. The present methodology has allowed unprecedented overall archaeometallurgical descriptions of these artefacts based on the detection of fine morphological details, degree of mineralisation, elemental and phase composition of the metal walls, and mineral contents of the core materials. Such an approach can be extended to other hollow copper alloy artefacts in order to identify their raw materials and interpret their technological processes.

Investigation of the Content of Ancient Tibetan Metallic Buddha Statues by Means of Neutron Imaging Methods

Many important cultural and religious objects from Asia consist of outer metallic shapes, usually bronze, which fully enclose inner contents made of organic materials such as wood, bark, paper, textile, plants and others. Bronze and other metallic materials, such as copper and silver, are generally more transparent to neutrons than to X‐rays. However, organic materials are less transparent to neutrons than to X‐rays and therefore organic materials, enclosed by metallic materials, can be made visible with neutrons. Therefore, neutron imaging (radiography and tomography) was found to be an ideal tool for the inspection of objects that consist of metal outside and organic materials inside. This has been successfully demonstrated here with four metallic Tibetan Buddha statues, providing archaeometry with a powerful new tool. The first successful applications of this novel technique are described in this article. Further possible and useful applications of neutron imaging of cultural objects are outlined.
