Tech Front


Symposium on Nanoscience and Nanomaterials in Mexico. “We are looking for solid materials that can store and release hydrogen easily,” said Olivia Graeve, a professor at the Jacobs School of Engineering at UC San Diego.


Storage of hydrogen has become increasingly important as hydrogen fuel cells become more popular power sources. But hydrogen, the lightest element on the periodic table, is difficult to store as it tends to diffuse through the walls of pressurized tanks, and it also needs to be compressed in order to occupy manageable amounts of space when stored. The resulting ceramics are crystalline structures in a cage of


boron. To store hydrogen, the researchers would swap the cal- cium, strontium and boron with hydrogen atoms within the cage. The researchers mixed boron with metal nitrates and organic fuels, such as urea, in a box furnace at temperatures below 400º C (752º F). The nitrates and organic fuels ignite, generating heat that then drives the reaction without the need for an external source of power, a method known as combustion synthesis. ME


Top-Flight Research Papers T


he recent International Manufacturing Research Conference 2014, held June 9–13 in Detroit, brought together research innovators who presented more than 350 papers at the co-locat- ed SME NAMRC, ASME MSEC and JSME ICM&P venues. Next month’s Tech Front will include full coverage of research presentations from NAMRC (sponsored by the North American Manufacturing Research Institution of SME), MSEC (Manufacturing Science and Engineering Conference), sponsored by the American Society of Mechanical Engineers’ Manufacturing Engineering Div., and ICM&P (International Conference on Materials and Processes), which is cosponsored by the Japan Society of Mechanical Engineers and ASME. Advance conference highlights include several papers from the 42nd NAMRC that earned high rankings in the peer- review process. The best paper distinction was awarded to “Fiber Orientation Angle Effects in Machining of Unidirectional
