• Where foam fits in medical design
  it isn't abrasive enough to harm patients' mouths and gums. Closed cell. Open cell. Reticulated. Foam can be processed to change its structure and properties. Foam offers designers a full palette of potential materials. They can use it to absorb, seal, filter, wick, cushion, insulate, or support...
• Vacuum Mixing Techniques (.pdf)
  Mixing under vacuum has a direct impact on end-product performance. Studies show that processing under vacuum reduces porosity and unbound particles. Reducing the number of pores leads to remarkable improvements in strength and fatigue life. By definition, vacuum refers to space absolutely devoid...
• Recent Advances in Pulsed Thermography
  data compression also occurs in TSR, facilitating rapid inspection of large. structures. Applications include thickness measurement of thermal barrier coatings or turbine blade walls,. corrosion detection and measurement of material loss, and measurement of porosity and backing film. inclusions...
• Plastics Consultancy Network - Analysis of plastics
  DSC (Differential Scanning Calorimetry) or DTA which gives you the melting points or gelation and sometimes the glass transition Tg, which is when the material softens from being a plastic into a rubber or elastomer. Only a few milligrams are needed in a sample pan which can be open, closed...

  it will begin production of the material later this year. A key to the SiLK advance is the researchers' ability to lower the material's density by introducing porosity. The reduction is the only way to lower dielectric values below 2.5, according to McClear. "For integration reasons, pore size needs...
• MICRO: The Hot Button
  node and below will be for patterned layers (CD, overlay, layer thickness, macrodefects), gate oxides (thickness, uniformity, nitrogen content), metal layers (filling quality, grain size, boundaries), and low-k materials (thickness, refractive index, porosity, composition, uniformity). Although...
• Superstrong parts
  the ability to produce superior quality metal parts in a wide array of sizes, shapes, materials, and finishes. Several well-known forging processes include impression or closed die, cold forging, and extrusion. There are also open-die and seamless-rolled-ring forging processes, each offering their own...
• Tight seals for the long haul
  help gauge which material will best give a long-lasting exterior seal: Closed-cell content: Seal and gasket materials typically contain a blend of both open and closed cells. Closed-cell content is often listed as low, medium, or high. Generally, foams rated high in closed-cell content have fewer...

  with high accuracy. Other substrate parameters such as porosity, texture, and stress can be measured as well. The systems use the company's X-Ray Microsource, which provides high x-ray flux on sample spots ranging in size from 500 500 um down to 100 100 um, which makes the tools suitable...
