Logging in natural γ-ray spectroscopy
Logging in natural γ-ray spectroscopy (NGS) is a technique used in the oil and gas industry to assess the content of specific materials in a specified area. This is achieved by measuring the energy of emitted γ-ray photons from natural sources, such as ura......
Introduction
Earth science downhole logging is a drilling engineering procedure that uses several methods to measure physical properties of rock formations present within a borehole. Downhole logging is used to assess the rock and fluid content around the borehole and to determine the characteris......
Introduction
The development of numerical control tool (NC) has made a great breakthrough in modern machining industry. It not only greatly improves the accuracy and efficiency of tool production, but also greatly reduces the labor intensity of operators and greatly increases the complexity of ma......
Ultraviolet and visible absorption spectrophotometers
Spectrophotometers are instruments used to measure how much light of a particular wavelength is absorbed by a sample. Absorbance is the fraction of light that is absorbed by the sample. These devices are used in a variety of applications, incl......
Spectroscopy is a major tool used in the study of the structure and properties of molecules. In the past, spectroscopists were limited to analyzing molecules in the lab. Today, advances in technology have given us the ability to analyze molecules in nearly any location. This has led to an explosio......
Nuclear Magnetic Resonance Spectroscopy (NMR), sometimes referred to as Magnetic Resonance Imaging (MRI), is a technique used to investigate the structure and dynamics of molecules. NMR spectroscopy is a powerful tool in studying proteins and other molecules, and it has become essential in the und......
Infrared semiconductor materials
Infrared radiation is a form of electromagnetic radiation with wavelengths longer than those of visible light. It is sometimes called infrared light. As with all types of electromagnetic radiation, infrared is affected by diffraction and polarization, and so can be......
Introduction
For a long time, bearings have played an important role in machinery. In order to reduce the vibration and thermal deformation of the machine and improve the working conditions, bearings need to be responsible for the obvious. However, due to the long-term operating conditions, beari......
Introduction
Dual frequency interferometers are interferometers that use optical instruments to measure the properties of a material or object to enable precise measurements of its size and shape. They can be used in a variety of applications including metrology, medical imaging, and spectroscopy.......
