Coming Soon - Electropolishing: Providing Solutions for Your Common Metal Finishing Problems

You may have heard of the term electropolishing but most likely don’t know how useful this reverse plating process can be. Regardless of the industry, manufacturers are faced with finish specifications that are becoming increasingly demanding. As a result, there is a need for secondary finishing processes that are both cost effective and reliable.

Ensuring Part Quality in Industrial Metal Additive Manufacturing

Concept Laser
Grapevine, TX

Now that metal additive manufacturing (AM) is creating fully functional industrial parts, many OEMs are taking a closer look at how the technology might support their individual production goals. Interest has also been piqued by the commitment to AM of some major companies. “I think the news about the GE Leap engine fuel nozzle really resonated throughout industry,” said Doug Hedges, President and COO of Sintavia LLC, a metal AM service provider for aerospace, defense, and other industries. “That got everyone's attention, and certainly increased the pace of inquiries for us.” The nozzle, produced internally at GE, was the first 3D-printed part certified by the U.S. Federal Aviation Administration (FAA) to fly inside a commercial jet engine.

New Class of ‘Soft’ Semiconductors Could Transform HD Displays

A new type of semiconductor may be coming to a high-definition display near you. Scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have shown that a class of semiconductor called halide perovskites can emit multiple, bright colors from a single nanowire at resolutions as small as 500 nanometers. The findings represent a clear challenge to quantum dot displays that rely upon traditional semiconductor nanocrystals to emit light. It could also influence the development of new applications in optoelectronics, photovoltaics, nanoscopic lasers, and ultrasensitive photodetectors, among others.

'Magic' Alloy Could Spur Next Generation of Solar Cells

In what could be a major step forward for a new generation of solar cells called "concentrator photovoltaics," University of Michigan researchers have developed a new semiconductor alloy that can capture the near-infrared light located on the leading edge of the visible light spectrum. Easier to manufacture and at least 25 percent less costly than previous formulations, it's believed to be the world's most cost-effective material that can capture near-infrared light—and is compatible with the gallium arsenide semiconductors often used in concentrator photovoltaics.

Adhesive Strength Enhancement of Shape Memory Polymer Composite and Metal Joint

This technology has applications in adaptive space structures, smart fabrics, intelligent medical devices, morphing structures, and packaging.

NASA Langley Research Center has developed technology to increase the adhesive strength between shape memory polymer composites (SMPs) and metal alloys. Shape memory materials, including SMPs, have been explored for numerous applications because of their unique shape memory capabilities. These materials can change shape and/or other properties in response to changes in an external stimulus such as stress, temperature, or an electric field.

System for Repairing Cracks in Structures

This thermally activated coating heals cracks in metallic materials.

NASA’s Langley Research Center has developed an innovative coating to heal cracks in metal components, such as in aircraft and bridges. Currently, the coating is used for in-laboratory repairs of surface cracks. Development continues with the ultimate goal of an in-situ healing mechanism that can work autonomously with structural health monitoring detectors.

Safer, Cleaner, Corrosion-Protecting Metal Coatings

LumiShield
Pittsburgh, PA
For more info click here

Corrosion-related issues cost the U.S. economy $276 billion a year. The Energy Department’s National Energy Technology Laboratory (NETL) teamed up with Carnegie Mellon University (CMU) to create a cost-effective technology to reduce that impact. The work resulted in the creation of LumiShield, a new CMU/NETL spinoff that signed a licensing agreement with the laboratory for the ionic liquid solvent for aluminum electroplating process.
