The NSF grant comes under the auspices of the Curriculum, Course & Lab Instrumentation Program, which focuses on new ways of teaching undergraduate science. This article is about five professors who were awarded an impressive National Science Foundation or NSF grant for the procurement of an environmental scanning electron microscope.
This article is about the adaptable and limitless use and power of the electron microscope.
In the late 1920s, electron microscope was invented and has been a most powerful and versatile tool for investigating the structure of cells, tissues, microorganisms and other microscopic objects. For the study of interfaces, boundaries, and various point, line, or planar […]
The topic in this link provides details and information on the functions of the electron microscope for the scientists in Beltsville Agricultural Research Center (BARC) in using high resolution imaging for each of their research programs. The instrument electron microscope unit is being described in this link as equipment with the modern state of the […]
Here is an article about endometrial cancer. Under an electron microscope, cancer cells can be revealed using tissue slides of microscopic tissues to be examined under the microscope. The endometrium is the lining of the uterus. The uterus is a hollow, muscular organ in a pelvis of a woman and the uterus is where a […]
This is an article about the first observation of the smallest and tiniest metal atoms seen under the electron microscope. For the first time researchers have used a transmission electron microscope, the One Angstrom Microscope or OÅM to image lithium atoms. Only atoms of hydrogen and helium are smaller and lighter than those of lithium, […]
Here is an article about imaging lithium atoms. For the first time researchers have used the One Angstrom Microscope or a transmission electron microscope at the Department of Energy’s National Center for Electron Microscopy, NCEM, at Lawrence Berkeley National Laboratory to image lithium atoms. Only atoms of hydrogen and helium are smaller and lighter than […]
Simple (one lens) microscope and the compound (many lenses) microscope are the two basic configurations of optical microscope. And all of them share the same basic components. The eye piece or the ocular is a canister that contains two or more lenses that brings the image to focus for the eye.
The first simple microscope was made and developed by Anton van Leeuwenhoek. Leeuwenhoek lived from 1632 to 1723. He made the early microcope that had one lens, thus it was called a simple microscope. Though it only had a single lens, it was said to have been regarded as the best microscopes of his time. […]
Before viewing the specimen under the electron microscope, there are different techniques done as sample preparation. The techniques to be done for a specific specimen would depend on the type of specimen and the type of analysis desired.
Some of the techniques commonly done for electron microscope specimen are cryofixation, fixation, embedding, dehydration, sectioning, staining, freeze […]
Electron Microscopes were developed due to the limitations of Light Microscopes. There are two general types of electron microscopes developed – the TEM or the transmission electron microscope, and the SEM or the scanning electron microscope. The Transmission Electron Microscope was the first type of Electron Microscope to be developed in the year of 1931. […]
