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

iScience, 2022 Summary: Three-dimensional (3D) histology is vitally important to characterize disease-induced tissue heterogeneity at the individual cell level. However, it remains challenging for both high-throughput 3D imaging and volumetric reconstruction.

Transmission electron microscopy characterisation of Spirulina bioplastics [PDF]
Journal of Microscopy, Volume 303, Issue 1, Page 101-119, July 2026.Abstract Plastic pollution is impacting global ecosystem health. Bioplastics made from unprocessed biomass, including whole or fragmented tissues, are one potential solution. They are biodegradable and exhibit competitive mechanical performance. Seaweed and microalgae have gained popularity over the last decade as bioplastic feedstocks due to their ...

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,

Label-free automated three-dimensional imaging of whole organs by microtomy-assisted photoacoustic microscopy [PDF]
Nature Communications, 2017 The state-of-the-art three-dimensional biomedical imaging often requires specific tissue preparation that may alter the physical properties of the specimen causing loss of information. Here Wong et al.

Critical Evaluation of Embedding Media for Histological Studies of Early Stages of Chick Embryo Development [PDF]
Methods and Protocols, 2023 A histological examination is an important tool in embryology, developmental biology, and correlated areas. Despite the amount of information available about tissue embedding and different media, there is a lack of information regarding best practices ...

Ontogeny and Homology of the Shoulder Joint and Forelimb Muscles in Frogs and Toads (Lissamphibia: Anura) [PDF]
Journal of Morphology, Volume 287, Issue 8, August 2026.The ontogenetic development, innervation, and morphology of the shoulder joint and forelimb muscles were investigated in 11 anuran species. The results reveal largely conserved splitting patterns of the dorsal and ventral pre‐muscle masses, alongside interspecific variation in muscle subdivision and morphology.

Deep Learning‐Based Tumor Cell Classification in Lung Adenocarcinoma With a Case‐by‐Case Human‐in‐the‐Loop Approach [PDF]
APMIS, Volume 134, Issue 4, April 2026.ABSTRACT Deep learning networks trained for classification of single cells in hematoxylin and eosin‐stained (H&E) sections are limited in accuracy. We hypothesize the accuracy of a pathologist to be 98%–100%. Digital classification should be on par with this to be relevant.

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
