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.

How knowledge of fiber properties led to the fabrication of a heart valve

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.

How SEM helps analyze morphologies for nanofibers efficiently

By Dr. Jasmin Zahn - Mar 9, 2017

Most of us may not be aware, but we are constantly surrounded by fibers. From tissue engineering to diapers, high technology filters are part of our daily lives. Many common, inexpensive polymers can be processed on a large scale into flexible materials. But not every produced fibrous material is ready for usage, such as in electronic devices, and further alterations of the material are needed. This blog will give you an insight into how scanning electron microscopy (SEM) can be used in the context of various nano-engineered fibers.
