Scanning electron microscopy
Scanning Electron Microscopy (SEM) is a powerful imaging technique used to observe the detailed surface structures of materials at a microscopic level. Instead of using light like traditional microscopes, SEM employs a focused beam of electrons. When these electrons hit a sample, they bounce off and create detailed images that reveal textures and features not visible to the naked eye. This method is crucial in fields like materials science, biology, and electronics, allowing researchers to analyze the composition and morphology of samples, leading to advancements in technology and understanding of various materials.

Scanning Electron Microscopy (SEM) is a powerful imaging technique used to observe the surface of materials at a very high resolution. Instead of using light, SEM employs a focused beam of electrons that scans the sample's surface. As the electrons interact with the material, they generate signals that are converted into detailed 3D images. This allows scientists and researchers to study the fine structures, textures, and compositions of various samples, including metals, biological specimens, and nanomaterials. SEM is vital in fields like materials science, biology, and nanotechnology.

Scanning electron microscopy (SEM) is a powerful imaging technique that uses a focused beam of electrons to scan the surface of a sample. Unlike traditional light microscopes, which use light to magnify, SEM produces detailed, three-dimensional images by detecting electrons emitted from the sample’s surface. This allows scientists to study the fine details of materials at a much higher resolution, revealing textures, structures, and compositions. SEM is widely used in various fields, including biology, materials science, and electronics, to analyze everything from tiny cells to the surface of metals.
