University of Texas at San Antonio
With a $1.2 million gift from the Robert J. Kleberg Jr. and Helen
C. Kleberg Foundation, a transmission electron microscope by JEOL Ltd. is now up
and running at the University of Texas at San Antonio’s Kleberg Advanced Microscopy
Laboratory. The microscope, model JEM-ARM200F, is anticipated to propel the development
of new cancer therapies and disease treatments by allowing nanotechnology researchers
to see samples magnified 20 million times their original size.

Glossary
- magnification
- The ratio of the size of the image of an object to that of the object. The ratio of the linear size of the image to that of the object is lateral magnification. Angular magnification is the ratio of the apparent angular size of the image observed through an optical device to that of the object viewed by the unaided eye. Longitudinal magnification is the ratio of the longitudinal or axial dimension of an image to the corresponding dimension of the object.
- nanotechnology
- The use of atoms, molecules and molecular-scale structures to enhance existing technology and develop new materials and devices. The goal of this technology is to manipulate atomic and molecular particles to create devices that are thousands of times smaller and faster than those of the current microtechnologies.
- transmission electron microscope
- A transmission electron microscope (TEM) is a powerful microscopy technique that uses a beam of electrons to create high-resolution images of extremely thin samples. In a TEM, electrons are transmitted through the sample rather than being bounced off its surface, as in scanning electron microscopy (SEM). The sample, typically prepared as an ultrathin section or a thin film, is placed in the path of the electron beam. As the electrons pass through the sample, they interact with its atoms,...
