DOC: PREPARATIONS OF SUPPORT FILMS FOR TEM GRIDS


In general, 200-400 mesh (lines/in) grids are used in TEM experiments. Most EM grids are made of copper because it is non-ferro magnetic and thus minimally distorts the magnetic field of the objective lens. The copper mesh also rapidly removes heat away from the support film and thus prevents thermal expansion and movement of the specimen under electron irradiation....

  PHYSIOLOGY PRACTICAL

... PHYSIOLOGY IS AN EXPERIMENTAL SCIENCE GAINING ITS KNOWLEDGE THROUGH OBSERVATIONS ON LIVING ANIMALS, ORGAN PREPARATIONS AND TISSUE CULTURES. OBSERVATIONS DURING MEDICAL PROCEDURES ON HUMAN BEINGS ALSO CONTRIBUTE TO THIS KNOWLEDGE. EXPERIMENTS DONE IN THE LABORATORIES SHOULD COMPLY WITH THE EXISTING LAWS AND REGULATIONS THAT ARE BASED ON BIOETHICAL PRINCIPLES. B IOETHICS IS AN INTERDISCIPLINARY SCIENCE DEALING WITH ETHICAL ISSUES CONCERNING BOTH BIOLOGICAL EXPERIMENTS AND MEDICAL PROCEDURES. IT IS RELATED TO THE NATURAL AND SOCIAL SCIENCES AS WELL. ...
