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.

Using a SEM in packaging material development and analysis

By Luigi Raspolini - October 25, 2018

Nowadays, the packaging industry is one of the fastest growing in terms of technology advancement and employing the latest available scientific developments. The reason lies in the greater demand for products and the upscale of shipments from regional transport to worldwide delivery. To ensure that the technologies are integrated in the right way, and to verify the quality of such introductions, more advanced inspection tools are required and scanning electron microscopes (SEM) play an increasingly important role in the material development. This blog will highlight some of the most common uses of electron microscopy within this field of application.

Why do your materials break? Tensile testing: inspecting the breaking mechanisms of materials with SEM

By Luigi Raspolini - September 27, 2018

Tensile testing is a commonly-used analysis that provides information on the resilience of an object and how much resistance it can offer to traction or compression. Such tests can be performed on a large variety of materials and provide useful information to speculate on the behavior of a material when it undergoes a stress. The main purpose of the tensile test is to evaluate relevant parameters (like the Young's modulus, for example) or to study the how shear stress affects the material. This allows researchers to create models and design better materials. But how can you see what is happening? A scanning electron microscope (SEM) with tensile testing capabilities can provide you with that information.

Microscopy resolution resolved! A simple explanation for an often misunderstood term

By Luigi Raspolini - March 24, 2017

There are different definitions of resolution and they depend on what kind of application you are working on. This blog's intent is to highlight and clarify the differences between the resolution of a LCD screen and the idea of resolution in microscopy.
