Transmission Electron Microscopes (TEM) and Scanning Electron Microscopes (SEM) are indispensable tools in modern scientific research. Compared to optical microscopes, electron microscopes offer higher resolution, allowing for the observation and study of specimens’ microstructure at a smaller scale. Electron microscopes can provide high-resolution and high-magnification images by utilizing the interactions between an electron beam and a specimen. This enables researchers to obtain critical information that may be difficult to obtain through other methods. Which microscope is more suitable for you? When choosing the appropriate electron microscopy technique for your needs, various factors need to be considered to determine the best fit. Here are some considerations that can…

Random Access Memory (RAM) is a crucial component in any computing device, responsible for temporarily storing data and instructions that the processor needs to perform tasks efficiently. Whether you’re upgrading your system or building a new one, understanding the different types of RAM and how they impact your system’s performance is essential. In this blog, we’ll explore the various types of Random Access Memory and guide you through choosing the right one for your needs, with insights on how GHT, a trusted RAM memory supplier, can provide high-quality memory solutions. 1. DRAM (Dynamic Random Access Memory) Dynamic RAM (DRAM) is the most…

When it comes to upgrading your computer’s storage performance, a Solid State Drive (SSD) is one of the best investments you can make. Unlike traditional hard drives (HDDs), SSDs offer faster speeds, increased durability, and better energy efficiency. But with so many options on the market, how do you choose the right one for your needs? In this blog, we’ll guide you through the key factors to consider when buying an SSD, and how to choose a reliable solid state drive supplier for your purchase. 1. Understand Your Storage Needs The first step in buying the right SSD is to determine your…

Since the discovery of the classic double helix structure of DNA by Watson and Crick in the 1950s, DNA has become the core of life science research. The number and arrangement of the four bases in DNA lead to genetic diversity, and its spatial structure affects gene expression. In addition to the traditional DNA double helix structure, a special four-stranded DNA structure called G-quadruplex has been discovered in human cells. G-quadruplex is a higher-order structure formed by the folding of DNA or RNA rich in tandem repeats of guanine (G). G-quadruplexes are highly abundant in rapidly dividing cells, such as…

The field of electron paramagnetic resonance (EPR) or electron spin resonance (ESR) made significant progress in 2024, with exciting developments and breakthroughs in a variety of areas. This blog post reviews the hot topics in the field of EPR over this year, highlighting the most notable achievements, emerging trends, and potential future directions. High-Resolution EPR: One of the major advances in the field of EPR in 2024 will be advances in high-resolution technology. Researchers have made great strides in improving the spectral resolution and sensitivity of EPR experiments. Advances in sample preparation, hardware design, and signal processing have increased spectral resolution, allowing for better resolution…

The Scanning Electron Microscope (SEM) is an important tool for observing micro-scale morphology and is widely used in fields such as materials science, biology, and environmental science. With the continuous development of technology, the Field Emission Scanning Electron Microscope (FESEM) has emerged. Compared to traditional SEM, FESEM offers advantages such as higher resolution, greater depth of field, and stronger signal stability. This article will provide a detailed introduction to the principles, characteristics, and advantages of FESEM compared to SEM. Principles of Field Emission Scanning Electron Microscope (FESEM): 1. Electron Source: FESEM uses a field emission electron source instead of the concurrent electron source used in SEM. The field emission electron source has higher…

Benchtop Electron Paramagnetic Resonance (EPR) spectrometers are compact, cost-effective, and user-friendly, making them ideal for labs with limited space or budgets. They provide reliable performance for analyzing free radicals, transition metals, and defects, with lower maintenance needs and simplified operation compared to traditional EPR systems. Several professional manufacturers in the United States offer benchtop EPR spectrometers. We have information here for researchers interested in purchasing one. Bruker Corporation: Bruker offers a range of Benchtop EPR instruments, including the EMXnano and EMXmicro series. Their instruments are known for their high sensitivity and versatility, allowing for a wide range of applications. CIQTEK: CIQTEK benchtop EPR spectrometers are…

Humans rely on their senses to perceive the world, and these microscopic analysis instruments extend human perception. We are all familiar with optical microscopes, but these microscopes, which work based on lens imaging, are limited by the Abbe limit, where the resolution is limited to half the wavelength of the light used. Therefore, the resolution of optical microscopes is only at the micrometer level due to the limitation of the wavelength of light. However, fast-moving electrons have wave-particle duality, and as a wave, an important characteristic of electrons is their wavelength. With increasing acceleration voltage, the electron wavelength decreases. By…
