Secret of Eumelanin’s Ability to Absorb Broad Spectrum of Light Uncovered

Melanin — and specifically, the form called eumelanin — is the primary pigment that gives humans the coloring of their skin, hair, and eyes. It protects the body from the hazards of ultraviolet and other radiation that can damage cells and lead to skin cancer. But the exact reason why the compound is so effective at blocking such a broad spectrum of sunlight has remained something of a mystery. Now, however, researchers at MIT and other institutions have solved that mystery, potentially opening the way for the development of synthetic materials that could have similar light-blocking properties.

Coming Soon - Virtual Fit-Ups: How to Eliminate Rework with 3D Measurement

When replacing equipment or components achieving accurate measurements can be very challenging, especially if the unit is still being used. A solution to this challenge is implementing portable CMM’s, such as laser trackers, to conduct virtual fit-ups. Conducting virtual fit-ups (ensuring parts will fit mating parts) allows for early verification of critical dimensions during disassembly. Stop wasting time and money on rework and get it done right the first time!

Fundamentals of Vector Network Analysis Primer

One of the most common measuring tasks in RF engineering involves analysis of circuits (networks). A network analyzer is an instrument that is designed to handle this job with great precision and efficiency. Circuits that can be analyzed using network analyzers range from simple devices such as filters and amplifiers to complex modules used in communications satellites

Oscilloscope Fundamentals Primer

The oscilloscope is arguably one of the most useful tools ever created for use by electronic engineers. In the more than five decades since the modern analog oscilloscope was created, hundreds of useful documents and thousands of articles have been written about what it is, how it works, how to use it, and application-specific examples of the “oscilloscope” in action. It is the purpose of this primer to instead describe digital oscilloscopes, which have for practical purposes replaced their analog predecessors in the vast majority of applications. Covered here is a short description of the oscilloscope’s origins, its transition from analog to digital, types of digital oscilloscopes and their major subsystems, key benchmark specifications, and measurements.

Physicists Create Water Tractor Beam

Physicists at The Australian National University have created a tractor beam on water, providing a radical new technique that could confine oil spills, manipulate floating objects or explain rips at the beach.The group discovered they can control water flow patterns with simple wave generators, enabling them to move floating objects at will. Advanced particle tracking tools revealed that the waves generate currents on the surface of the water.“We have figured out a way of creating waves that can force a floating object to move against the direction of the wave,” said Dr Horst Punzmann, from the Research School of Physics and Engineering, who led the project.SourceAlso: Learn about a Floating Oil-Spill Containment Device.

Magnetics Design: Specification, Performance & Economics

An informative white paper from Datatronics Romoland, Inc., provides a discussion of the design, development and delivery of affordable magnetic components. The design development process begins once performance requirements are specified. Upon design approval, the procurement of materials for a prototype build is initiated. During this stage, specifications are not final and options remain open for cost-effective production. Specifications must be reviewed and design trade-offs evaluated to ensure that the technical requirements are economically attainable with consideration given to performance and tolerance in relation to affordable cost.
