Controlling Surface Chemistry and Morphology to Promote or Prevent Adhesion

We encounter interfacial interactions every day. Our tires grip the road because frictional forces between the rubber and concrete prevent tires from slipping. Conditioner moisturizes hair because it is designed to make contact with each strand to deliver moisturizing agents that separate the strands. Not unlike these interactions, the ability to controllably alter interfacial or adhesion interactions is important for a wide variety of industries from aerospace to marine to space exploration. To control interfacial interactions, both surface chemistry and topography play vital roles.

A Design Engineer's Guide to Specifying Custom Bearings: Optimizing Features and Cost

As an engineer, one of the first lessons of design is to specify standard products if possible. With today’s demands for smaller, more reliable and more cost efficient products, engineers are often faced with significant design and performance challenges. So why should an engineer consider specifying a custom bearing?

Why Does Your Product Break?

Fatigue is often cited as one of the most common forms of operational failure in structures. Its nature is an often apparently premature failure at relatively low, but cycling, stress levels.

High-Performance, Thermally Insensitive Optics

Silicon Carbide has a unique set of thermal and mechanical properties that make it an ideal material for some reflective optics systems. The difficulty of manufacturing lightweight structures with SiC, however, has limited its use to substrates attached to benches made of more forgiving materials.

Improved Configuration Management in Aerospace Electrical Design

Configuration management of design data is a big challenge in aerospace electrical design. Creating, tracking, and checking the many variants of individual features is a challenge both from the standpoint of electrical integrity -“Does this configuration operate correctly?”; and from the standpoint of data management – “How to manage multiple effectivities without massive data duplication?”

Fluid Structure Coupling Technology

NASA Marshall Space Flight Center's Fluid Structure Coupling (FSC) technology is a highly efficient and passive method to control the way fluids and structures communicate and dictate the behavior of a system. Developed to solve a difficult structural dynamics issue of a national asset, an FSC device weighing less than 200 lbs successfully mitigated a potentially detrimental resonant response of this 650,000 lb structure.
