How does a scanning electron microscope work?5 answersA scanning electron microscope (SEM) works by using high voltage to accelerate electrons, which are then focused onto the sample. As the electron beam scans the surface of the sample, electrons and material atoms interact, producing electrons and X-rays that are collected by detectors. These signals are converted into digital signals and displayed on a computer screen, providing information about the microstructure of the sample. SEMs have a higher resolution and focusing depth compared to optical microscopes, making them more effective for microstructural analysis. SEMs can also perform microchemical analysis, including elemental analysis using energy dispersive X-ray (EDX). The SEM imaging technique has been improved with features such as backscattered electrons and secondary electrons. The electron gun, along with other components, is the heart of the SEM. Different types of electron guns, magnetic lenses, and vacuum systems contribute to the unique imaging capabilities of SEM. The scanning electron microscope described inincludes an electron optical tube to generate and focus the electron beam, as well as probes to receive electrons and photons from the sample. The scanning electron microscope inincludes a sliding vacuum seal and a detector that can be moved relative to the electron beam. The scanning electron microscope inincludes a surface height measurement system using a spectral interference displacement meter and an objective lens control unit for correcting the focal position of the electron beam.
Who invented CT scan?3 answersThe CT scan was invented by Godfrey Hounsfield and Allan Cormack. They independently developed the technology and were awarded the Nobel Prize in Physics and Medicine in 1979 for their discovery. Hounsfield designed the CT scanner, which allowed for the reconstruction of three-dimensional images from X-ray projections taken at regular angles. Cormack, on the other hand, worked on developing algorithms for effective scanning of the human body. Despite never meeting and being unaware of each other's work, Hounsfield and Cormack made significant contributions to the development of X-ray computed tomography, revolutionizing diagnostic medicine.
How to use scanning tunneling microscope?5 answersScanning tunneling microscopy (STM) is a technique used for obtaining high-resolution images and manipulating single atoms/molecules on a substrate. It is beneficial for studying materials at the atomic scale and has potential applications in various fields such as surface science, solid-state physics, biology, and organic chemistry. An RF reflectometry scanning tunneling microscope utilizes a probe, an RF resonant circuit, a directional coupler, and an RF signal measuring device to observe the surface of an object and generate a scanning result based on the reflected RF signal. STM is the first scanning probe microscope used for atomic-scale imaging of conducting materials. It operates by converting the distance between the tip and the surface into electric current and allows for the control of tip position and data recording for surface mapping. Other scanning microscopes, such as atomic force microscopy (AFM), electrostatic force microscopy (EFM), scanning thermal microscopy (SThM), and scanning near-field optical microscopy (SNOM), have also been developed. The principles and practical aspects of STM techniques, including scanning tunneling spectroscopy (STS), are outlined, along with examples, data analysis, sample preparations, and common problems encountered in STM experiments.
