Battery research with a Scanning Electron Microscope: inspecting one layer at a time

By Luigi Raspolini - August 8, 2019

Batteries revolutionized the world of electronics by enabling us to carry an energy reserve in our pockets. Miniaturization and efficiency are the two key words when it comes to new developments in this field, impacting with the battery materials’ properties and stretching their limits. Let’s take a look at how researchers characterize materials and gather relevant information about batteries using scanning electron microscopy (SEM).

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.

What is depth of field and how can I optimize it in a scanning electron microscope?

By Luigi Raspolini - July 25, 2019

Imaging with a scanning electron microscope (SEM) consists of taking pictures of small features. So why not consider a comparison with photography? Let’s analyze how similar the behaviors of a SEM and a camera are when it comes to focusing on your subject, and what the exact definition of depth of field is.

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 to prevent oxidative damage to a scanning electron microscope sample

By Luigi Raspolini - June 27, 2019

O2 is an extremely reactive gas, and some materials don’t get along well with it. Oxidation processes are activated as soon as certain samples are exposed to the atmosphere and this affects the structure and characteristics of the samples — in most cases permanently. This blog explains how oxidative damage can be prevented and how SEM analysis can be performed on oxygen-sensitive samples without compromising the structure of the sample itself.

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.

70 Years of Electron Microscopy: The History of the Thermo Scientific Phenom Desktop Scanning Electron Microscope

By Rose Helweg - June 18, 2019

About 70 years ago, Philips built its first commercial electron microscope. This microscope made electron microscopy available to researchers worldwide. Now, 70 years later, electron microscopy plays a fundamental role in research done in various fields, ranging from materials science to life sciences. A big role in making electron microscopy accessible to everybody is played by the Phenom Desktop SEM, originally launched in 2006.
