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

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

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

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.

Corrosion-Inhibiting Self-Expanding Foam

Surfaces such as metal and other corrodible surfaces are often exposed to extreme weathering, temperatures, moisture, impurities, and otherwise damaging external forces that accelerate corrosion. Conventional methods of corrosion protection include applying paints and other coatings, such as petroleum-based undercoatings, with a sprayer to the exposed surface. To be effective, the entire exposed surface must be covered or the corrosion process will be accelerated at the unprotected areas. While open-area surfaces may be easier to protect, those surfaces found in internal cavities within an overall framework can be more challenging to protect. Achieving full coverage on internal surfaces can be extremely difficult, and in some cases impossible without drilling several access openings in the structure. These extraneous openings can compromise the strength of the structure as well as create more entryways for water and debris. This increases the opportunity for corrosion to initiate at the edges of the openings.

Reusable Sponge Absorbs Oil from Entire Water Column

When the Deepwater Horizon drilling pipe blew out seven years ago, beginning the worst oil spill in U.S. history, those in charge of the recovery discovered that the millions of gallons of oil bubbling from the sea floor weren’t all collecting on the surface where it could be skimmed or burned. Some of it was forming a plume and drifting under the surface of the ocean.
