In today's world of rapidly advancing technology, scientific breakthroughs rely heavily on our ability to visualize and understand materials at the smallest scales. One such tool of considerable importance is the field emission scanning electron microscope (FE SEM), and the CIQTEK SEM5000 stands out for its superior imaging capabilities and versatility. In this blog post, we will delve into the fa...
Electron paramagnetic resonance (EPR) spectroscopy is a powerful technique used to study the electronic structure of paramagnetic substances. It provides valuable insights into the nature and interactions of unpaired electrons in magnetic fields. Selection rules in EPR spectroscopy establish conditions that allow or prohibit leaps between different energy levels. Understanding these selection rule...
Scanning electron microscopes (SEMs) are highly advanced and sophisticated scientific instruments that provide high-resolution imaging and analysis of samples at the nanoscale level. There are several renowned scanning electron microscope brands available in Europe that offer state-of-the-art SEMs. Here are a few notable brands: FEI Company (Thermo Fisher Scientific): FEI Company is a leadi...
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...
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...
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...
