American Ceramic Society Recognizes Dr. Singh with President’s Award
July 25, 2009 – 3:12 pm
Dr. Mrityunjay Singh has received the prestigious “President Award” from the American Ceramic Society for his sustained service and remarkable contributions to the American Ceramic Society and global leadership in the field of ceramics. In the more than 110 year history of the society, this award has been given only few times to select individuals. Dr. Singh has served and is currently serving on various society level award committees, and strategic and long term planning committees. He played a key role in raising funds for the Richard M. Fulrath Endowment of the society.
Dr. Bansal Appointed to Advisory Board of the Ceramic Science Journal
July 4, 2009 – 2:40 pm
Narottam P. Bansal of the Ceramics Branch has been appointed as a member of the International Editorial Advisory Board of the Ceramic Science Journal published by Bentham Science publishers. This peer-reviewed journal publishes full length research articles, research reviews, and letters in all areas of ceramic science, technology, and applications.
Patent Awarded for NASA Solid Oxide Fuel Cell
June 12, 2009 – 3:09 pm
United States Patent number 7,534,519 was issued May 19 on Symmetrical, Bi-Electrode Supported Solid Oxide Fuel Cells (SOFC). The patent is for a novel design of fuel cells, where the fuel and air are fed into the fuel cell by tiny micro-channels in the electrodes, rather than by large, heavy metal plates. This allows removal of the large heavy plates which account for most of the weight and volume in planar SOFCs.
The NASA SOFC design, called the “BSC” for bi-supported, is all ceramic. Tests on the cell have shown excellent performance, including in the regenerative mode of operation where the cell runs in electrolysis mode. The superior electrolysis capabilities of this design have been confirmed by an independent group at the DOE Idaho National Laboratory, where they are producing hydrogen from the hot steam exiting nuclear reactors.
Work to prototype this SOFC design is being conducted by the Ceramics Branch at NASA Glenn Research Center. A second patent, on the stack of cells, is expected to be granted in the next couple months. Two companies are interested in the patent rights and GRC is actively submitting proposals with both companies to increase research funds.
Ceramic Integration Technology Work Highlighted on the Cover of International Ceramics Journal
April 11, 2009 – 3:00 pm
A paper authored by Dr. Mrityunjay Singh (Ceramics Branch/OAI) and Prof. Rajiv Asthana, University of Wisconsin-Stout on the “Joining and Integration of Zirconium Diboride -based Ultra-High Temperature Ceramic Composites to Copper-clad- Molybdenum for Advanced Aerospace Applications” was published in the March 2009 issue of International Journal of Applied Ceramic Technology. This paper documented the results of four different types of interface (braze) materials and three types of composites and the influence of various factors on the properties.
This topical issue was devoted to “High Temperature Ceramic Matrix Composites.” This journal is published by the American Ceramic Society and Wiley-Blackwell and is one of the leading journals in the ceramics field. The photographs from this paper were featured on the cover page of the journal. This work was supported by the Hypersonics project of the Fundamental Aeronautics program.
Dr. Mrityunjay Singh Selected as Recipient of Prestigious Lee Hsun Lecture Award
February 13, 2009 – 12:54 pm
Dr. Mrityunjay Singh received this award in recognition of his accomplishments in materials science and technology research. The Lee Hsun Lecture Award is annually administered by the Shenyang National Laboratory for Materials Science (SYNL) in China and the Institute of Metal Research, Chinese Academy of Sciences (IMR CAS). As an award recipient, Singh has been invited to visit IMR in Shenyang, China to give a lecture and thus further advance the scientific cooperation between research institutions in both countries.
Dr. Narottam Bansal Is Editor of International Symposium Proceeding Volume
February 13, 2009 – 12:49 pm
A proceeding volume of the 5th international symposium "Solid Oxide Fuel Cells: Materials, Science, and Technology," co-edited by Dr. Narottam Bansal of the Ceramics Branch, has been published recently by John-Wiley for the American Ceramic Society. The symposium, held during January 27 to February 1, 2008 in Daytona Beach, FL., had a total of 120 papers, with participation of researchers from 17 countries.
The proceedings volume contains contributions describing the current status of solid oxide fuel cell technology and the latest developments in the areas of fabrication, characterization, testing, performance analysis, long term stability, anodes, cathodes, electrolytes, interconnects and protective coatings, seals, cells and stack design, protonic conductors, electrolyzers, etc.
SiC/SiC Ceramic Matrix Composite Stress Damage Paper Published
December 5, 2008 – 2:53 pm
The article entitled "Tensile creep and fatigue of Sylramic-iBN melt-infiltrated SiC matrix composites: Retained properties, damage development, and failure mechanisms" by Gregory N. Morscher, Greg Ojard, Robert Miller, Yasser Gowayed, Unni Santhosh, Jalees Ahmad, and Reji John was recently published in Composite Science and Technology vol. 68, no. 15-16, pp. 3305-3313 (2008). This represents a collaborative effort among Pratt and Whitney, RAI, University of Auburn, OAI, and Air Force under a PRDA contract with Pratt and Whitney.
Significant stress rupture and low to high cycle fatigue data at 1200C in air is represented on the NASA developed N24A Syramic-iBN, slurry cast melt-infiltrated SiC/SiC composite system. The paper focuses on damage (matrix cracking) development over the range of stresses and times tested, the failure mechanisms over the stress ranges tested as it relates to the damage state, and retained properties of specimens that did not fail after the stress-oxidation condition.
