Why SEM is the most suitable microscopy technique for fiber analysis

By Karl Kersten - Sep 1, 2017

Fibers are all around us. Different types of fibers exist, but in most cases we do not notice them because they are used in a product. In case an object is much longer as it is wide we consider it a fiber. Fibers have specific properties for the product in which they are used. This blog will describe the different ways how these fibers can be classified and how their performance can best be analysed. Hint: it has something to do with putting fibers under a specific type of microscope. You're about to discover the most suitable microscopy technique for fiber analysis, so do read on!

How next-generation composite materials are created and analysed

By Luigi Raspolini - Jul 6, 2017

The technical specifications of next-generation materials are taking our technology to a completely new level, allowing us to create products with outstanding properties that were impossible to achieve in the past. These materials are the result of a huge drive toward innovation in material science and could only be achieved because of the invention of the first composite materials and their introduction into the industrial landscape.

In this article, I describe how these next-generation materials are being developed — and equally important: how their chemical composition is analysed, and their performance is measured.

SEM: types of electrons, their detection and the information they provide

By Antonis Nanakoudis - Jun 29, 2017

Electron microscopes are very versatile instruments, which can provide different types of information depending on the user’s needs. In this blog we will describe the different types of electrons that are produced in a SEM, how they are detected and the type of information that they can provide.

Imaging fibers with a SEM: how to obtain a flawless quality analysis

By Marijke Scotuzzi - Jun 22, 2017

In our daily life, we make use of a large amount of objects and devices that are produced from fibers. Fibers are usually imaged in a scanning electron microscope (SEM), which provides high-resolution images, elemental analysis, and the possibility of automatically measuring thousands of fibers in mere minutes. But in some cases, imaging fibers with a SEM also presents challenges, as the nature of some fibers might compromise the quality of your analysis. With this in mind, this blog describes how you can obtain a high analysis quality through proper SEM configuration and sample preparation.

How engineers and researchers can boost polymers properties with SEM

By Luigi Raspolini - Jun 16, 2017

Polymers have many uses and applications: engineered combinations of monomers produce a nearly infinite number of molecules with different properties, which are determined by the chemical composition and structure of the molecule. The form of the molecule has a big influence on how the polymer will behave when exposed to different external forces. In this blog, you’ll find practical examples of how Scanning Electron Microscopes (SEMs) can provide unexpected results.

How SEM helps discover suitable corrosion inhibitors

By Dr. Jasmin Zahn - Jun 12, 2017

Many industries would benefit from the inhibition of corrosion in metals. In the materials science field, scientists are therefore exploring ways to prevent or reduce corrosion. Many studies looking for suitable corrosion inhibitors have been carried out.

However, most of the inhibitors discovered and developed during those studies were synthetic chemicals, which are very expensive, and hazardous to the environment. Due to the characteristics of these chemicals, studies were carried out to investigate and analyze natural products that could be used as an anti-corrosion agent. SEM technology helped conduct these studies in an effective manner, something we will describe further in this article.

What is SEM? SEM technology explained

By Antonis Nanakoudis - Jun 1, 2017

Scanning electron microscopy (SEM) has become a powerful and versatile tool for material characterization. This is especially so in recent years, due to the continuous shrinking of the dimension of materials used in various applications. In this blog, we describe the main working principles of a SEM instrument.

Is a desktop SEM the best choice for my application?

By Karl Kersten - Feb 9, 2017

You know you need more SEM capability. Maybe you have a traditional floor model SEM, but it is slow and complicated to operate. Maybe you are using an outside service and the turn-around time is unacceptably long. You’ve made your case that your company could significantly improve their business performance and you could do your job better if SEM imaging and analysis were easier, faster and more accessible. Can a desktop SEM do what you need?

How this engineering company supercharged their R&D process

By Karl Kersten - Dec 9, 2016

As device dimensions are shrinking, researchers are required to work on nanoscale levels. As a result, new technology is needed to create and evaluate structures. Luckily in turn, the physical size of this technology is getting smaller too.
