How next-generation composite materials are manufactured and analysed

By Luigi Raspolini - Mar 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 - Feb 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 - Jan 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 - Nov 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.

How research on new material can help minimize environmental damage

By Karl Kersten - Nov 8, 2018

In science, efforts are rising exploring options that help minimize environmental damage. To understand how environmental damage can be minimized it is worthwhile to research new materials. We would like to show you an example taken from fiber development to illustrate the possibilities new materials provide. This example is particularly interesting for anyone working in the materials science field.

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

By Luigi Raspolini - Sep 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.

Additive manufacturing: improving the quality of AM processes through SEM analysis

By Antonis Nanakoudis - May 17, 2018

In a previous blog, we introduced Additive Manufacturing (AM) as a new manufacturing approach and described its key points (you can read the blog here). Additive Manufacturing, also known as 3D printing or rapid prototyping, has attracted the attention of many people and industries around the world due to its unlimited and promising potential. In this blog we will describe how the use of a Scanning Electron Microscope (SEM) can be a powerful tool to monitor and improve the quality of additive manufacturingprocesses.

Effective asbestos detection with a Scanning Electron Microscope (SEM)

By Luigi Raspolini - May 10, 2018

Resistance to fire, sound absorption, tensile strength and low price caused a boost in asbestos mining activities at the beginning of 19th century.

Already used in the production of asphalt, brake pads, electrical insulators, fireproof suits, technical fabrics and other everyday products, asbestos started its golden century when the Austrian engineer Ludwig Hatschek invented the first asbestos-cement, often mistakenly referred to as Eternit.

The material properties, particularly its lightness and resilience, started a real revolution in the construction engineering and asbestos-cements factories, which immediately emerged all over the world.
