Electron paramagnetic resonance (EPR) spectroscopy is a powerful experimental technique for studying paramagnetic species' electronic structure and properties. In EPR spectroscopy, the g-value plays a crucial role in understanding the behavior and environment of unpaired electrons in paramagnetic systems. This article aims to provide an overview of g-values and their significance in EPR spectrosco...
In microscopic imaging, two dominant techniques have revolutionized our understanding of the complexity of the nanoworld: scanning electron microscopy (SEM) and transmission electron microscopy (TEM). These powerful tools have opened up new avenues for a variety of scientific disciplines, allowing researchers to delve into the composition, structure, and behavior of a wide range of materials. We c...
The scanning electron microscope (SEM) is an advanced scientific instrument to image and analyze high-resolution samples. Several countries in the Middle East have well-established scientific research institutes and universities, with Saudi Arabia, the United Arab Emirates (UAE), Turkey, Egypt, and Iraq investing heavily in scientific research and development, including scanning electron microscop...
The sensitivity of a spectroscopic technique refers to its ability to detect and analyze signals from a sample. In the case of electron paramagnetic resonance (EPR or ESR) and nuclear magnetic resonance (NMR), EPR is generally considered to be more sensitive than NMR for several reasons: 1. Detection principle EPR detects signals from unpaired electrons, while NMR detects signals from the n...
EPR (Electron Paramagnetic Resonance) Spectroscopy, also known as Electron Spin Resonance (ESR) Spectroscopy, is a technique used to study the electronic structure of paramagnetic species. There are two main types of EPR spectroscopy: Continuous Wave (CW) EPR spectroscopy and Pulsed EPR spectroscopy. Continuous wave (CW) EPR Spectroscopy: In continuous wave EPR spectroscopy, a microw...
Scanning Electron Microscopy (SEM) is based on the principle of using a focused beam of high-energy electrons to probe the surface of a sample and produce a high-resolution detailed image. Electron Source: SEM works by using an electron source, typically a heated tungsten filament or a field emission gun, to produce a beam of electrons. Electron Beam Generation: The electron source e...
The Scanning Electron Microscope (SEM) is a powerful tool for various applications in material sciences, life sciences, and other fields. Different kinds of detectors have been developed to obtain more information and improve the performance of SEM. The following are a few common types of SEM detectors: Backscattered Electron Detector (BSE): BSE detectors are used to detect electrons scatte...
ESR (Electron Spin Resonance) and EPR (Electron Paramagnetic Resonance) are used interchangeably to describe the same spectroscopic technique. The reason for the two different names can be traced to the historical development of the field and some of the interesting stories surrounding it. Originally, the technique was called ESR, or electron spin resonance. It was discovered in the mid-20t...
