For decades, a laboratory procedure known as transmission electron microscopy (TEM) has been used to test for asbestos in samples taken at construction sites. In 1989, the U.S. Environmental ...

The U.S. Food and Drug Administration (FDA) announced on April 5, 2024, the results of its 2023 sampling assignment, testing talc-containing cosmetic products for the presence of asbestos. The testing ...

As discussed in the Product Perspective, the Modernization of Cosmetics Regulation Act of 2022 (MoCRA) represents a major shift in cosmetic industry regulations. This article, in a continuing series ...

TEM works by transmitting a beam of electrons through an ultra-thin specimen. As the electrons interact with the specimen, they are scattered or transmitted, producing an image that is magnified and ...

Support grids are a key part of electron microscopy measurements; the choice of the grid can directly influence the quality and accuracy of the final image. This is particularly true for transmission ...

Today, the Council formally adopted new rules on protecting workers from the risks related to exposure to asbestos at work. This directive updates the existing rules in line with the latest scientific ...

Electron microscopy is a powerful technique that provides high-resolution images by focusing a beam of electrons to reveal fine structural details in biological and material specimens. 2 Because ...

With the inventions of transmission electron microscopy (TEM) in 1931 and scanning electron microscopy (SEM) shortly after in 1937, scientists gained an unprecedented ultrastructural view of the ...
