How scanning electron microscopy impacts dental studies

By Dr. Jasmin Zahn - Dec 14, 2017

Microscopy is known to be a versatile tool in dental studies. Not only is optical microscopy used in day-to-day practices in dental clinics, but due to the surface information electron microscopy offers, it is used within a large variety of research subjects. With the following examples we want to offer more insights into how in detail scanning electron microscopy (SEM) is utilized within various dental studies.

The strong connection between microscopy and micro-organisms

By Dr. Jasmin Zahn - Nov 30, 2017

The human body is host to billions of micro-organisms of many kinds and has as many human cells as non-human ones! These micro-organisms are mainly harmless bacteria; in fact, they can sometimes be helpful. Due to their size, a distinction and characterization is always done with microscopy. Over the many, many years that micro-organisms have been observed, different types of microscopy have been used, from classical optical microscopy to scanning electron microscopy (SEM). In this blog, we showcase three examples of how micro-organisms were studied with the help of microscopy.

How does blood research benefit from scanning electron microscopy?

By Dr. Jasmin Zahn - Nov 16, 2017

Blood is a vital element of the body. It is essential to all organs and tissues as it provides the oxygen that is required and removes unwanted metabolites from cells. But blood isn’t just involved in oxygen transportation, it also contains immune cells and platelets that help defend the body from various diseases and are involved in bleeding disorders. This blog will give you more insights into how scanning electron microscopes (SEMs) can become an important tool for laboratories that focus on blood research and related fields.

How SEM analysis helps understanding new nanofiber applications

By Dr. Jasmin Zahn - Oct 26, 2017

How to transfer drugs into human bodies efficient and while doing that minimizing side effects, has been studied intensively, and many different techniques have been developed over the past few years. Electrospun nanofibers are one of such new systems that have attracted a lot of attention recently. This is thanks to the exceptional properties of these fibers: they have highly porous three-dimensional surfaces, a high surface-to-volume ratio, and interconnected porosity with tunable pore dimensions. Scanning electron microscopy (SEM) proved to be helpful as an analytical tool to understand how fiber properties can be altered and enhanced.

Scanning electron microscopy analysis of polymer coatings of stents

By Dr. Jasmin Zahn - Oct 5, 2017

The development of polymers and their diverse range of applications is a wide research field. Polymer materials became prevalent in implantable medical devices through processing capabilities in a wide variety of physical and chemical properties, as well as biocompatibility. This article describes how polymer coatings are used in the fabrication of drug-eluting coronary stents and how scanning electron microscopy (SEM) helps analyze the performance of these coatings in great detail.

How SEM revealed a solution to enhance hemp fibers for better properties

By Dr. Jasmin Zahn - Jul 26, 2017

Industrial hemp is one of the fastest growing plants and was one of the first plants used for the production of fibers about 10,000 years ago. Hemp fiber has been used extensively throughout history, with production climaxing soon after it was introduced to the New World. Read this blog to discover how hemp fibers can be used even more extensively because of better fiber properties, and how SEM helped reveal the solution that realizes these improvements.

How SEM helps discover suitable corrosion inhibitors

By Dr. Jasmin Zahn - Jun 12, 2017

Many industries would benefit from the inhibition of corrosion in metals. In the materials science field, scientists are therefore exploring ways to prevent or reduce corrosion. Many studies looking for suitable corrosion inhibitors have been carried out.

However, most of the inhibitors discovered and developed during those studies were synthetic chemicals, which are very expensive, and hazardous to the environment. Due to the characteristics of these chemicals, studies were carried out to investigate and analyze natural products that could be used as an anti-corrosion agent. SEM technology helped conduct these studies in an effective manner, something we will describe further in this article.

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

By Dr. Jasmin Zahn - Apr 26, 2017

3D printing, or additive manufacturing (AM), refers to processes that are used to make 3D printed objects. In order to achieve this, successive layers of material are formed under computer control to create an object. The objects can have almost any shape or geometry and are produced using digital data from a 3D model or other electronic data source. But successive layers formed under computer control can result in structural interruptions that negatively affect the reliability of an object. And these undesirable interruptions should not go undetected; something we discuss in this blog later on. But first, more about 3D printing.

By Dr. Jasmin Zahn - Apr 13, 2017

These days, fibers and fiber materials can be found in endless applications. A wide range of these materials is used everywhere from baby diapers to water filters, from applications in asbestos to the automotive industry. Because of their widespread use, a lot of research is carried out to alter fiber materials and enhance their properties. This includes research on components as well as on fiber preparation technologies. One example is the fabrication of a heart valve using differently engineered fibers, which is described in this blog in more detail.
