Preparation of Zeolites for TEM Using Microtomy [PDF]
MRS Proceedings, 1987 ABSTRACTThe application of microtomy to Transmission Electron Microscopy (TEM) specimen preparation of zeolite catalysts is explained. Using a new acrylic resin (LR White®) thin sections (≤60 nm) may be cut with relative ease. Although the details described are specific to catalysts, microtomy and the use of the acrylic resin are applicable to any hard

Optik & Photonik, 2007 AbstractThe laser microtome (LMT) has been designed to slice biological tissue and various materials with high precision. The cutting process is performed by ultra short laser pulses in the near infrared region, inducing an optical breakdown below the surface of the material. Biological Tissue can be processed in its native state without prior fixation

Microtomy of Large Particle Zeolites for Tem [PDF]
MRS Proceedings, 1990 ABSTRACTUniformly thin specimens of powders, suitable for electron microscopy, can be prepared by ultramicrotomy. There is a size limit to the particles that can be studied since larger particles tend to be dislodged from the available resins when microtomed. A method is described to strengthen the binding of the organic resin to the inorganic zeolite,

Ultrasonically Assisted Cutting of Bio-tissues in Microtomy
Physics Procedia, 2016 Modern-day histology of bio-tissues for supporting stratified medicine diagnoses requires high-precision cutting to ensure high quality extremely thin specimens used in analysis. Additionally, the cutting quality is significantly affected by a wide variety of soft and hard tissues in the samples.

CODEX Microtomy Tracking Sheet v1 [PDF]
, 2019 Microtomy Tracking Sheet for CODEX Specimens The process of sectioning CODEX specimens presents tediously at the tissue block trimming and microtomy stage. As you begin to cut into a new or already used tissue block, you must keep track of how many microns of tissue are removed from the section during trimming, and also during microtomy. Attached is a

Three-dimensional cardiac architecture determined by two-photon microtomy [PDF]
Journal of Biomedical Optics, 2009 Cardiac architecture is inherently three-dimensional, yet most characterizations rely on two-dimensional histological slices or dissociated cells, which remove the native geometry of the heart. We previously developed a method for labeling intact heart sections without dissociation and imaging large volumes while preserving their three-dimensional ...

Electron Microtomy Training: A Self-Contained Learning Package [PDF]
Proceedings, annual meeting, Electron Microscopy Society of America, 1972 An electron microtomy training program has been prepared and tested at junior college, state college and university levels. This program consists of 5 basic units: fixation, dehydration, embedding, sectioning and staining. The materials, planned and prepared by utilizing modern educational theory, are designed to be largely self-instructional.

Effect of old age on the subpopulations of enteric glial cells in human descending colon
Glia, Volume 71, Issue 2, Page 305-316, February 2023., 2023 Main Points The number of Sox‐10 immunoreactive (IR) enteric glial cells (EGCs) were unaltered with age in both the myenteric and submucous plexus. The density of S100‐IR EGCs declined among the elderly in the circular muscle and within the myenteric plexus per ganglionic area.

Influence of microtomy on measurements of orientation
Polymer Testing, 1994 Abstract The correct measurement of orientation and crystallinity on thin sections microtomed from larger specimens requires a knowledge of the influence of sectioning on these properties. In this work, the measuring technique used is FTIR, using dichroism to determine the orientation and regular FTIR to determine the degree of crystallinity.
