Microfabricated Particles as MRI Contrast Agents

Potential applications exist in MRIs, drug development, diagnostics, and microfluidics.

Magnetic resonance imaging (MRI) has become an invaluable, widely used medical diagnostic and research tool, but despite numerous chemically synthesized image-enhancing agents, MRI still lacks the sensitivity and the multiplexing capabilities of optical imaging that benefit from colored fluorophores — multi-spectral quantum dots for multi-functional encoding and biomolecular/cellular labeling.

Self-Protected, Low-Temperature Nanosolder

The nanosolder is inexpensive and easy to use in an assembly process.

Nanosolders allow for increased capabilities in the formation of soldered interconnections for heat-sensitive electronic packages. The desired characteristic of nanosolder is to have a low process temperature that does not damage base materials or components, while also having a high service temperature that allows the product to operate in harsh environments.

Resistive Heating-Assisted Infiltration and Cure (RHAIC) for Polymer/Carbon Nanotube Structural Composites

This process can be used for airframe components, lightweight construction structures, thermal management, and electromagnetic shielding for cars.

NASA’s Langley Research Center scientists have developed a process for fabricating carbon nanotube (CNT) structural nanocomposites that brings CNT-based composites closer to realizing their potential for structural applications. Conventional methods fail to properly wet CNTs within the epoxy matrix due to high resin viscosity, resulting in poor infiltration and reduced load transfer between the CNTs and matrix. The NASA process — resistive heating-assisted epoxy infiltration (RHAEI) — uses the CNTs’ electrical resistance to generate heat, which reduces epoxy resin viscosity for greater CNT wetting and adhesion. Mechanical properties are significantly improved compared to conventional methods. NASA’s process has been demonstrated to offer 50% improvement in strength and elastic modulus, with mechanical properties competitive with structural carbon fiber composites.

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.
