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

Dynamic analysis of double-helical gear system considering effect of oil film among meshing teeth
Advances in Mechanical Engineering, 2020 The oil film among meshing teeth is just like a spring-damping element, and it can dominate the friction and meshing characteristics of the gear pair and influence its dynamic performances further.

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,

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

Acta Botânica Brasílica, 2014 The traditional techniques employed for embedding plant samples are not suitable for the proper processing of small seeds with hard seed coats. Usually, these seeds are broken off from blocks during microtomy, which limits the technical success of this ...

Construção de um micrótomo de congelamento a partir da adaptação de um micrótomo de parafina
Brazilian Archives of Biology and Technology, 1998 A microtome for frozen sections was developed using the facilities and equipment available in our country. The requirements for making it were: 1) fast frozen of the tissue, 2) easy histological procedure, 3) no necessity of long period for preparation ...
