Sample preparation techniques for SEM to neutralize the effect of vacuum

By Luigi Raspolini - May 23, 2019

Scanning electron microscopes (SEM) scan the surface of the sample with an electron beam, collecting reflected electrons which carry information about the material the electrons interact with. If gas is in the sample chamber, its atoms interact with the beam, partly deflecting electrons and adding noise to the image. 

This is the reason why vacuum must be achieved in SEM before imaging. But while vacuum is crucial for proper analysis, it can also have a negative effect on certain types of materials. Read this blog to learn how you can neutralize vacuum and keep your samples intact.

Why hi-tech textile engineering requires SEM for fiber analysis

By Luigi Raspolini - April 25, 2019

It’s been a long time since the textile industry relied exclusively on natural fibers. Over the decades, synthetic fibers have proven to be cheaper, easier to produce and often perform better. At the same time, chemical treatments have been developed that improve the smoothness and the resistance of both natural and synthetic fibers, which has resulted in higher quality products. Read this blog for more information on how electron microscopy can play a fundamental role in the textile engineering and fiber analysis process.

Sample tilting in scanning electron microscopy: how to keep the area of interest within the field of view

By Luigi Raspolini - April 18, 2019

Certain samples are tricky to image. Sometimes, even the best sample preparation will be 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.

How next-generation composite materials are manufactured and analysed

By Luigi Raspolini - March 7, 2019

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.

How engineers and researchers can boost polymers properties with SEM

By Luigi Raspolini - February 7, 2019

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.

Why the plastics industry relies heavily on microscopy analysis

By Luigi Raspolini - January 24, 2019

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.

The revolution in asbestos analysis

By Luigi Raspolini - November 30, 2018

The detection of asbestos fibers is a complex and time-consuming operation, requiring the use of electron microscopes and highly trained operators. This results in high costs for the analysis and a slow throughput. What if the microscope could support the operator with an automated fiber detection routine and cut the time (and cost) required for each analysis? Find out how in this blog.
