Specimen preparation for X-ray micro-computed tomography of forest pests

Applied Microscopy
X-ray micro-computed tomography (XCT) is an X-ray-based three-dimensional (3D) imaging technique that enables non-destructive imaging of both external and internal structures. It is widely used for studying biological specimens such as animals and plants.

A Comprehensive Study of Laboratory-Based Micro-CT for 3D Virtual Histology of Human FFPE Tissue Blocks

IEEE Access
Advances in laboratory-based X-ray computed tomography (CT) have enabled X-ray 3D virtual histology. This method shows a great potential as a complementary technique to conventional 2D histology where extensive volumetric sampling is necessary.

Moldavite porosity: a 3-D X-ray micro-tomography study

European Journal of Mineralogy, 2013
Moldavites are natural glasses formed by distal ejection of meteorite-impact melts; they occur in several shapes ( e.g ., teardrops, lenticular, dumbbells, spheres) and all contain pores in different sizes. The aim of this study is to describe the distribution of pores in the interior of the scanned objects.

Interconnectivity of habitats in soil:combining X-ray micro tomography and thin sectioning to reveal fungal-soil structure interactions [PDF]

, 2009
The extreme heterogeneity and interconnectivity of the 3-dimensional pore space within soil makes it a unique habitat for the diverse microbial population and has a pivotal role in microbial interactions.

Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing

Advanced Engineering Materials, EarlyView.
This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...

X-ray micro-tomography examination of specimens of deciduous teeth

Varna Medical Forum, 2016
Увод: Утвърдените класически методи на диагностика и лечение на кариеса на временните зъби изискват преосмисляне и промени, налагани от подхода за лечение в медицината. До скоро зъбният кариес се приемаше като ,,инфекциозно` заболяване. От конгреса на FDI, 2012 г., зъбният кариес се приема като ,,поведенческо заболяване с бактериален компонент`.
