SEM stands for scanning electron microscope. The SEM is a microscope that uses electrons instead of light to form an image. Since their development in the early 1950's, scanning electron microscopes ...

Today we are machining some metal inside the scanning electron microscope! By creating a custom fixture, we can manually ...

Oregon State University researchers have synthesized new molecules able to quickly capture significant amounts of carbon ...

Researchers at Caltech have developed bioresorbable acoustic microrobots (BAM) capable of delivering therapeutic drugs ...

Photosynthesis, the process by which plants, algae and certain kinds of bacteria convert solar radiation into chemical energy ...

Deriving starch nanofibers directly from plants is a process that is both energy and water intensive. A team led by chemist ...

Researchers have created organic materials for brain and heart pacemakers, which rely on uninterrupted signal delivery to be effective. Using a plastic base known as polypropylene, the researchers ...

Transmission electron microscopy generates an image of the internal structure of a thin sample. Scanning electron microscopy generates a topological image of a sample. The mechanisms of antibiotic ...

Traditionally, scanning electron microscopy (SEM) has been an effective tool to examine nanoscale structures. SEM works by scanning a sample with a focused electron beam and capturing the SEs ...
