Effective asbestos analysis with a Scanning Electron Microscope (SEM)

By Luigi Raspolini - August 1, 2019

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.

How SEM helps to detect additive manufacturing defects in a 3D-printed object

By Antonis Nanakoudis - July 18, 2019

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 the additive manufacturingprocesses.

How SEM helps research polymers characteristics, properties, and uses

By Luigi Raspolini - July 11, 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.

SEM as a fiber analysis method for filtration systems quality control

By Luigi Raspolini - July 4, 2019

The production of filters and membranes undergoes several quality control steps to ensure that the properties of the product are up to specification. Different methods can be used for such fiber analysis, but only one can provide the best results. Find out in this blog how Scanning Electron Microscopes (SEM) can be used to investigate imperfections in metallic filters.

How a desktop SEM saves lab operators a lot of time

By Karl Kersten - June 20, 2019

Is it true that as a lab operator, you work under constant time pressure? Do you find it challenging to deliver output quickly? And does it take hard work to maintain your high standard of quality? This blogs explains how a desktop scanning electron microscope (SEM) can be used to increase your research productivity and therefore to save a lot of time.

How electron microscopy fuels the development of eco-friendly polymers

By Luigi Raspolini - May 16, 2019

Thermosetting polymers are widely used in modern industry due to their specific chemical and physical properties. With a wide range of applications, from components of huge aircraft to small electronics, epoxies are one of the main products of the polymers industry. This blog will focus on how these polymers are improved and made eco-friendly, by making use of a scanning electron microscope (SEM).

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.

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.
