App Note | Technology: Optical Tensiometry
Wettability and Adhesion Problems for Polypropylene (PP) Products When applying coatings, inks, adhesives, and other materials to a surface, controlling the surface properties becomes critical. In particular, the wettability – the ability of the process liquid to spread and adhere to the solid surface –…
App Note | Technology: Force Tensiometry
How the Attension Sigma 702ET Quickly and Easily Monitors the Interfacial Tension and Quality of Transformer Oil Transformers account for nearly 60% of the cost of high voltage substations [1], and the time to repair some transformers is over one year [2]. Given the long…
App Note | Technology: Ion Milling
High Resolution Electron Back Scatter Diffraction (EBSD) and Scanning Electron Microscope (SEM) Surface/Cross Section Sample Preparation In Electron Back Scatter Diffraction (EBSD) studies, surface quality is a key issue. Diffraction patterns are formed within a few tens of nanometers of the sample surface. A crystalline,…
App Note | Technology: Ion Milling
Focused Ion Beam (FIB) Sample Milling for High Performance Transmission Electron Microscopy Investigation (TEM) The use of focused ion beam (FIB) systems has become the method of choice for site-specific transmission electron microcscopy (TEM) sample preparation. Although focused ion beam offers advantages over conventional mechanical…
App Note | Technology: Scanning Electron Microscopy
Fractography is a method in failure analysis for studying the fracture surface of materials. Studying the characteristics of the fractured surface can help to determine the cause of failure in an engineered product. Different modes of failure produce characteristic features on the surface, allowing a…
App Note | Technology: Scanning Electron Microscopy
Fiber-based filtration systems clean everything from the air we breathe to the oil that runs our engines. Many filters, like high-efficiency particulate air (HEPA) and ultra-low particulate air (ULPA) filters, are made from glass or polymer fibers. Some are a woven mesh of metal fibers,…
App Note | Technology: Scanning Electron Microscopy
Filtration and fibers used to separate liquids from particles or particles from air play an important role in our everyday lives. Filters help to clean air, water or oil for automobiles, this important product plays a major role in keeping our lives running at their…
App Note | Technology: Scanning Electron Microscopy
Ceramics often have grain sizes and microstructure that impact material performance. Scanning electron microscope (SEM) images are used to quantify the grain sizes and distribution. Grain boundaries and microstructure can be optimized with ceramic processing parameters for specific product requirements. Ceramic Grain Size and Coverage Backscattered…
App Note | Technology:
Ceramics typically include a combination of ionic and covalent bonds to form a material with high modulus and hardness, high melting point, high thermal expansion and corrosion resistance. Because these materials may be brittle, fracture toughness is also an important mechanical property. Composites are made from…
App Note | Technology: Electrospinning
There are multiple manufacturing processes for fiber production. Depending on the physical and/or chemical properties of the materials to be used in some techniques are more feasible than others. Common techniques include 3D printing, hot melt extrusion, and electrospinning. Among these, the electrospinning technique, which…
