Getting the Most Out of Industrial CT Scanning

Quality assurance and flight certification of critical aerospace parts and assemblies have reached new levels of sophistication in recent years. Leading aerospace and defense manufacturers worldwide now consider computed tomography (CT) scanning to be an essential part of their non-destructive testing (NDT) toolkit. Far more powerful than the CT used to scan the human body, industrial CT can penetrate almost every material, from superalloys to lead, revealing hidden details that previously could only be found by cutting and destroying finished parts.

Machining Titanium Aero-Frames

The rise of titanium for aerospace applications has been well documented in recent years. Equally, the challenges associated with the efficient, productive and high-quality machining of this popular material, have also been a topic of debate and scrutiny. Of course, every machine shop wants optimized performance from its cutters when milling titanium, but this can prove less than straightforward without the right technology and know-how in place. Today, however, thanks to a breakthrough in this area, things are beginning to change.

Electrical Characterization of Crystalline UO2, THO2 and U0.71TH0.29O2

Tracking and identifying radiation sources in the age of nuclear proliferation and well- resourced non-state actors is a national priority. Current neutron detection methods favor large detector volumes and long data collection times. Additionally, portable neutron detection methods have persistent problems with low signal-to-noise (small pulse height) and require large applied voltages.

Matrix-Free Assisted Laser Desorption Ionization Using Metal-Organic Frameworks

Matrix-assisted laser desorption/ionization (MALDI) is a soft ionization technique that is widely applied in the characterization of large biomolecules using various mass spectrometry (MS) analyzers, specifically, time-of-flight (TOF) analyzers. The MALDI process involves the deposition of an analyte solution onto a metal substrate before the addition of a matrix. The matrix/analyte dry spot is exposed to a UV laser, and the laser energy that is absorbed by the matrix/analyte is converted into heat energy that initiates charge transfer, which results in the desorption of the matrix and analyte molecules in ionized form. The positive ions are then accelerated through a vacuum into MS analyses.

US and Japanese Scientists Conduct Joint Composites Study

Dr. Keisuke Umezawa of the Air Systems Research Center in the Japanese Ministry of Defense (JMoD) recently joined the Air Force Research Laboratory on an engineers and scientists exchange program (ESEP). The JMoD chose Umezawa for the ESEP based on his experience as a stress analysist of polymer matrix composite materials. Also, Umezawa has been heavily involved in the development of the next generation Japanese fighter aircraft, including the development of the test program for prototype PMC structures.

NASA to Advance Unique 3D Printed Sensor Technology

Mahmooda Sultana recently won funding to advance a potentially revolutionary, nanomaterial-based detector platform. The technology is capable of sensing everything from minute concentrations of gases and vapor, atmospheric pressure and temperature, and then transmitting that data via a wireless antenna — all from the same self-contained platform that measures just two-by-three-inches in size.
