| What's New at Engineers Edge! |
| Tiny vibrating "microcantilevers" improve sensor performance - Researchers have learned how to improve the performance of sensors that use tiny vibrating "microcantilevers," like the one pictured here, to detect chemical and biological agents for applications from national security to food processing. (Vijay Kumar, Birck Nanotechnology Center, Purdue University. |
| Welding nanowires with light - At the nano level, researchers at Stanford have discovered a new way to weld together meshes of tiny wires. Their work could lead to innovative electronics and solar applications. To succeed, they called upon plasmonics.

| Pelton Wheel Review - Modern impulse turbines are generally know as Pelton type and are restricted to relatively high-head applications . One or more jets of water impinge on a wheel containing many curved buckets. |
| Orthopedic implants "dip-coated" aids in bone repair - When William Murphy works with some of the most powerful tools in biology, he thinks about making tools that can fit together. These constructions sound a bit like socket wrenches, which can be assembled to turn a half-inch nut in tight quarters, or to loosen a rusted-tight one-inch bolt using a very persuasive lever. |
| Open-source fluid dynamics design software - Stanford University Unstructured (SU2) is an open-source software package that gives advanced engineering students a crucial leg up on the time-consuming process of writing their own code to optimize aerospace designs - offering for free what commercial applications command thousands of dollars to do. |
| Stress Concentration Fundamentals - Stress concentration is defined as - Localized stress considerably higher than average (even in uniformly loaded cross sections of uniform thickness) due to abrupt changes in geometry or localized loading. |
