Mold design, fabrication and tensile testing of EMBed-812, a tissue embedding epoxy resin
Serial sectioning is a process whereby fixed tissue is embedded in a polymer to preserve structure and is then sliced into very thin sections as small as 25nm. Currently, there is a lack of understanding of this embedding material, preventing accurate and clean slicing at this level of precision. …

Silver Diffusion and Isotope Effect in Silver-Rubidium-Iodide
… superionic phases using radiotracer Ag-110m and serial sectioning with a low temperature sectioning apparatus. The activation energies for diffusion in alpha-RbAg(,4)I(,5) and beta-RbAg(,4)I(,5), respectively, are .11 (+OR-) .01 eV and .20 (+OR-) .04 eV. These values are the same, within …

Thin-source concentration dependent diffusion
… source of Ca tracer, rectangular geometry, and serial sectioning. The l6 2 pre-diffusion surface concentration was approximately 3xlO(Ca)-atoms!cm, which, for an average penetration depth of IOOum-300um, produces a maximum (post-diffusion) impurity concentration comparable to or greater than the …

Percolation Paths of Three-Dimensions in Sensitized Stainless Steel
… in a three-dimensional model created through serial sectioning. Evidence is presented that triple or quadruple points that contain typically two boundaries with special character that intersect the percolation path break up the path. Some grains with no known special qualities (i.e., CSL) have …

Recovering Grain Boundary Inclination Parameters Through Oblique Double-Sectioning
… character distribution by oblique double-sectioning is proposed. The method, which is similar to the recovery of the orientation distributions from sets of incomplete pole-figures, is described along with a framework for implementation. The method directly measures grain boundary …

Effect of Nonequilibrium Defects Due to Phase Transformation on Diffusion in Beta Zirconium
… diffusivities of two samples were measured by serial sectioning and counting techniques. Appropriate correction methods were derived, for each set, to identify the proper interface because of the unique sectioning problems encountered.

The phytoplankton of a eutrophic lake : community dynamics and ultrastructural studies
… and scale formation in Synura petersenii, serial sectioning and 3-dimensional representation of the transverse flagellum of Peridinium cinctum and a study of the surface morphology of the scale-bearing Heliozoan Raphidocystis tubifera.

Effects of Voids on Delamination Behavior Under Static and Fatigue Mode I and Mode II
… methods; ultrasonic scanning, epoxy burn off, serial sectioning and X-Ray computed tomography. The effect of voids on both mode I and mode II interlaminar fracture toughness under static and fatigue loading was investigated. Finally, fractographic analysis (using optical and scanning electron …

Microstructural formations and phase transformation pathways in tantalum carbides
… TaO through selected area electron diffraction. Serial sectioning and 3D reconstruction was used to quantify the globular oxide structure. Finally, a thermo-mechanical testing apparatus has been constructed where an electrical current provides resistive heating and, in the presence of a magnetic …

The Use of Preclinical Models to Improve the Treatment of Retinoblastoma
… to the gold standard of enucleation, embedding, serial sectioning and hand tracing. It was found that there was a better correlation between the ultrasound and hand tracing histological sections.</p> <p>Concurrently, the tumor progression of six different genotypes was assessed. The tumor …

Segmented images and surface models made of serially-sectioned images of cadaver head
PURPOSE: Purpose of this research is to present serially-sectioned images of cadaver head with 0.1 mm intervals and 0.1 mm pixel size, accompanied by coronal and sagittal images, which are helpful in interpreting MRIs. Another purpose is to present segmented images and surface models (three …

Batch processing of brain tissue sections for millimeter-scale serial section transmission electron microscopy connectomics
… rapidly collecting neuroanatomical datasets with serial section transmission electron microscopy (ssTEM). In the cerebral cortex, for instance, a local circuit is contained in a cubic millimeter, but single sections—obtained by cutting brain samples with a diamond knife—must be “ultrathin” (< 40 …
