SEM sample tilting: how to keep the area of interest within the field of view

By Luigi Raspolini - Aug 10, 2017

Certain samples are tricky to image. Sometimes, even the best sample preparation will be of no help in finding the results you need. Surface roughness and features on top of the sample might hide the specific area of interest, which could contain crucial information about surface defects or characteristics of the imaged material. In cases like this, you need a new point of view. Read this blog to discover how you can get just that.

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.

Why the plastics industry relies heavily on microscopy analysis

By Luigi Raspolini - May 26, 2017

Ever since oil became fundamental to industry, scientists and engineers from all around the world have carried out more and more research into how different organic molecules can be combined in certain patterns to obtain new materials with amazing properties. Commonly called plastics, they are known to the scientific community as polymers — chemical compounds with a highly-engineered chemical structure and composition. The analysis of these compounds is crucial in helping to improve polymer production processes. This article discusses how electron microscopy can provide the analysis that polymer developers need to improve product quality significantly.

Why SEM is the go-to technology for microfabrication evaluation

By Jake Wilkinson - May 19, 2017

The world of microfabrication is in a constant state of flux. With new technologies, new applications and more difficult problems to be solved, microfabrication is developing at such a speed that it will soon touch all our lives. In the past, microfabrication has been limited to using carbon and semi-conductor materials. But now, new commercial laser techniques, such as those used in the Technology & Applications Center (TAC) at Newport Corporation, are expanding the scope of microfabrication. The range of materials that can be worked on has been extended into polymers, composites, dielectrics and even ceramics.
