SEMINARS ******************** 3.1: Wednesday, April 2, 2008, 6:00PM, MRGN 121: Bioethics Seminar, ³Conflicts of Interest in Biomedicine,² by David Resnik. Issues surrounding conflicts of interest and the commercialization of research are both timely and vital to Purdue¹s research community. BIO: Dr. Resnik is the Bioethicist for the NIH and the NIEHS. His extensive experience and publication record both in philosophy and in the sciences promise this to be a very interesting talk! More information, including Resnik¹s CV, is available online at www.purdue.edu/bioethics <file://www.purdue.edu/bioethics>. 3.2: Friday, April 4, 2008, 3:30 refreshments, 3:45 sminar, ARMS 1010: ³Laser Weldability of Nickel and Cobalt Based Alloys,² by Henry J. White, Haynes International, Kokomo, IN ABSTRACT: For nearly a century, arc welding has been the primary technique used to join both nickel and cobalt based alloys. The advantages (excellent corrosion resistance, increased productivity, etc.) of a deep and narrow weld geometry with a limited heat affected zone led to the first detailed study of laser welding of Hastelloy® and other nickel based alloys- Welding Journal 1986. A modification of the ³Weeter Laser Weldability Test² was used to evaluate eighteen commercially available and five experimental alloys produced by Haynes International. The original test involves drilling a matrix of holes of various diameters (0.343 to 0.572 mm) and depths (0.127 to 0.508 mm) in the material. Then a laser (Nd- YAG, CO2, Fiber, etc.) is used to make spot welds in the drilled holes. A laser spot size greater than the drilled hole diameter is selected so that the absence of metal in the drilled hole causes the solidified spot weld to have a concave contour. By varying the depth and width of the drilled hole the weld restraint and the depth of the cavity resulting from the solidified spot weld changes. By measuring the depth of the cavity at which the alloy exhibits incipient cracking, ³Weeter index², a rating of the material¹s weldability is obtained. In this study a ramp (depth from 0.127 to 0.508 mm) / taper (width from 0.343 to 0.572 mm) geometry was machined into each specimen. A Fiber Laser (IPG Photonics) was used to produce an autogeneous bead on plate weld in the ramp/ taper region. A laser spot size, greater than the restraint area, was used to ensure that the resulting cavity assumes a concave contour. As in the original test procedure, the cavity depth at which the alloy exhibits incipient cracking was measured/ recorded and used as a rating of the material¹s weldability. We will report on the laser weldability of corrosion resistant (Hastelloy B-3®, C-4, C-22®, C-276, C-2000®, G-3, G-30®, G-35®), high temperature (Haynes® 25, HR-120®, HR-160®, 188, 230®, 242®, 282®, 556®, 625, Hastelloy X), and five experimental alloys which have been/ will be used in the chemical, hygienic, aerospace, and the automotive industries. We will compare these test results with Varestraint Testing (a technique used to evaluate the arc weldability of materials) done on the same materials and comment on hot cracking propensity/ mechanisms. SHORT BIO: Dr. Henry J. White, a Registered Professional Engineer in the State of Indiana, joined Haynes International in 2007 as Welding Metallurgist/ Senior Staff Engineer. He has a B.S. in Metallurgical Engineering from Polytechnic University, M.S. in Materials Science and Engineering (Welding Metallurgy) from The University of Tennessee, Knoxville, and Ph.D. in Materials Science and Engineering from SUNY Stony Brook. After completing his BS, Dr. White worked as a Metallurgical Engineering for ABB Lummus Global where he developed/ reviewed welding procedure specification/ procedure qualification records and selected material of construction for Ethylene, Styrene, and Maleic Anhydride petrochemical plants. After completing his MS, Dr. White worked for Misonix Incorporated as a Materials Engineer where he developed welding procedures and selected materials for ultrasonic medical instrumentation. While in graduate school, Dr. White managed the heat treatment facilities for Skyo Industries Inc. a mill to market torsion tool manufacturer. At Skyo Industries Inc., Dr. White designed new materials and heat treatment procedures to improve and maintain tool quality. Dr. White was a member of the faculty in the Materials Science and Engineering Department at Stony Brook University from 1996-2007. During this period he was an National Science Foundation Career Awardee, Chairman of the Metro NY/ NJ Chapter of the American Society of Materials International, Accreditation Board of Engineering & Technology Materials Science and Engineering Program Evaluator, and Subject Matter Expert for the National Council of Examiners for Engineering and Surveying. He continues to participate in the later two activities. *********************** 4. DISCOVERY PARK NEWS *********************** 4.1: Burton Morgan building: security procedures adjusted: Effective March 31st, the building will be locked at 6:00 p.m. There will no longer be a student hired to ³sit² in the building. When events are scheduled in the building during the evenings or weekends, Denny Heath will hire students from the Purdue Security and Safety Patrol (PSSP) as needed to keep an eye on the facility. There will be a charge for this service, which runs ~$10.00/hour with a minimum charge of $30.00. If a DP Staff Member will be acting as the guest liaison for your event and wants to assume the responsibility for building security we would need to know this at the time the room reservation is made. In these instances, we would not need to hire the student patrol. All groups outside of Discovery Park will automatically be required to use the student patrol service. When a late reservation request is made (1-2 weeks), and a PSSP cannot be hired due to student availability, the building doors will be locked at 6pm. It will be the responsibility of the guest liaison to make arrangements to gain access to the building and to open the main doors for their attendees. These arrangements can be made through Denny Heath and/or Valerie Lawless. These procedures are consistent with University Policy and will help us safeguard the facility. Reservations should be requested by e-mail to Ruth Ann Weiderhaft at weiderhaft(a)purdue.edu. The request should include the name of the group, date/time # of people, and room requested. When events and meetings are scheduled in the building outside of regular hours, Ruth Ann Weiderhaft will forward a request to Denny Heath and Valerie Lawless to keep the building unlocked for the meeting time. This will also be the time when patrol students will be requested as needed.

ABSTRACT: Fabrication of Nano-Electro-Mechanical-Systems (NEMS) of high quality is nowadays extremely efficient. These NEMS will be used as sensors and actuators in integrated systems. Their use however raises questions about their interface (actuation, detection, read out) with external detection and control systems. Their operation implies many fundamental questions related to single particle effects such as Coulomb blockade, light matter interactions such as radiation pressure, thermal effects, Casimir forces and the coupling of nanosystems to external world (thermal fluctuations, back action effect). Here we specifically present how the thermal fluctuations of an oscillating cantilever can be damped using three radically different ways: i) an electro-mechanical coupling in the presence of a strong Johnson noise ii) an external feedback control of thermal fluctuations. This is the cold damping. It is closely related to Maxwell's demon iii) a cavity Fabry Perot induced photothermal pressure that can quench the brownian vibrational fluctuations of an AFM lever. This shows how the interplay between MEMS or NEMS external control and their coupling to a thermal bath can lead to a wealth of effects that are nowadays extensively studied in different areas. 3.2: Friday, 03.28.08, 3:30 refreshments; 3:45 seminar, ARMS 1010: ³Getting the Pb Out: Whisker and Hillock Growth from Sn Electrodeposits,² William J. Boettinger, Metallurgy Division, NIST. ABSTRACT: For many years, electronic component leads made of Cu alloys were ³pretinned² with a 3 to 10 micron layer of electrodeposited tin-lead (Sn-Pb) alloy to maintain proper solder wetting during subsequent assembly. The worldwide electronics industry is in the process of removing Pb from their components. When Pb is removed from the electroplated surface finishes, Sn whiskers grow spontaneously from the surface finish. The whiskers are single crystal filaments typically 1 µm in diameter and several mm long. Numerous electronic failures due to shorting from whiskers have been reported, especially in the high reliability realm of aerospace, military, and medical device applications. This lecture will describe progress being made towards developing a fundamental understanding of Sn whisker growth and providing industry with information needed for mitigation strategies. See http://nepp.nasa.gov/whisker/ <http://nepp.nasa.gov/whisker/> for general information about the Sn whisker problem. BIO: William J. Boettinger is a NIST Fellow in the Metallurgy Division of the Materials Science and Engineering Laboratory at NIST in Gaithersburg, MD. He earned a B.E.S. (Mechanics) in 1968 and a Ph.D. (Metallurgy) in 1972 from The Johns Hopkins University. Before joining the permanent staff at NIST, he was a NRC/NAE postdoctoral research associate at NIST from 1972-1974. From 1977 until 1995 he held a concurrent position as a professorial lecturer at the George Washington University where he taught a graduate course in phase transformations. His expertise includes the thermodynamics and kinetics of metallurgical systems especially the relationship of alloy microstructure to processing conditions. He has over one hundred fifty publications on topics including dendritic, eutectic and peritectic solidification, rapid solidification, phase diagrams, diffusion, intermetallic compounds, measurement of crystal perfection using x-rays, and soldering. Research with J. A. Warren on phase field modeling of solidification was recognized in the 11 May 1995 issue of Nature.¹ Dr. Boettinger was awarded the Department of Commerce Bronze Medal in 1980, Silver Medals in 1983 and 1994, and Gold Medals in 1999 and 2003. He received the Materials Science Division Award of the American Society for Materials (ASM) in 1989 and was made a fellow of that society in 1994. He co-chaired the 1994 Physical Metallurgy Gordon Research Conference with J. H. Perepezko. He has received several honors from The Minerals, Metals and Materials Society (TMS): the 1999 Champion Mathewson Best Paper Award, the 2001 TMS Bruce Chalmers Award for research in solidification and a Fellow in 2006. He was named a NIST Fellow in 2001, elected a member of the National Academy of Engineering in 2006 and received the federal government¹s Presidential Rank Award in 2007. **************** 4.

ABSTRACT: As the semiconductor industry moves beyond the 45nm node and as systems become more mixed signal in nature, System on Chip (SoC) solutions are facing major barriers due to technical and business related reasons. This is leading to the development of alternate technological solutions such as System on Package (SoP). SoP, a technology being pioneered by Georgia Tech, allows for integration of functions in the substrate. Higher levels of integration are being achieved by embedding functions in the package and merging the package and board. In this presentation aspects of RF and digital integration will be discussed in the context of System on Package implementation. BIO: Madhavan Swaminathan is the Joseph M. Pettit Professor in Electronics in the School of Electrical and Computer Engineering and Deputy Director of the Packaging Research Center, Georgia Tech. He is the co-founder of Jacket Micro Devices, a company specializing in RF substrates and modules for WLAN and WiMAX applications. He has over 300 publications in refereed journals and conferences, 15 patents and is the author and co-author of two books ³Power Integrity Modeling and Design for Semiconductors and Systems², Prentice Hall, 2007 and ³Introduction to SOP², McGraw Hill, 2008. Prior to joining Georgia Tech, he was with IBM working on the packaging for supercomputers. Madhavan is a Fellow of IEEE and is one of the pioneers of SOP technology at Georgia Tech. 3.2: Friday, 03.21.08, 3:30 refreshments, 3:45 seminar, ARMS 1010: ³Rapid Hydrogen Detection by Nanoscale Palladium and Quantitative Measurement of Hydrogen Uptake Using a Quartz Crystal Microbalance,² by Dr. Tao Xu, Department of Chemistry and Biochemistry, Northern Illinois University. ABSTRACT: Rapid detection of low-concentration hydrogen gas leaks under ambient temperature is crucial for the safe application of future hydrogen-driven vehicles. In conventional palladium-based hydrogen sensors, the decrease of the conductance of Pd upon absorption of hydrogen serves as the sensing mechanism. We show that an opposite phenomenon occurs in a percolating Pd nanocluster film, whose conductance increases upon its absorption of hydrogen. The mechanism is based on the swelling of the Pd nanoclusters, thus narrowing/closing the inter-nanocluster gaps, which creates extra conducting pathways in the film. Further improvement is achieved by placing a siloxane self-assembled monolayer between a substrate and an evaporated discontinuous ultra-thin Palladium (Pd) film, which promotes the formation of smaller Pd nanoclusters and narrower inter-cluster gaps, and reduces the stiction between the Pd and the substrate. As a result, the film can detect 2% H2 with a rapid response time of ~70 ms and is sensitive to 25 ppm hydrogen. Hydrogen uptake in storage materials often occurs at high pressure. Conventional volumetric and gravimetric methods suffer from large sample quantity, the inevitable leak of hydrogen at high pressure and the correction of buoyancy force, etc. We demonstrate the application of a piezoelectric quartz crystal microbalance (QCM) for quantitative measurement of hydrogen mass uptake in storage materials up to 40 bar. Due to the high sensitivity of the QCM (<1ng/cm2), only miniature sample is required. The frequency shift of a quartz crystal coated with hydrogen absorbing materials is affected by the hydrogen mass uptake on the crystal, the pressure and the viscosity of the gases, and the crystal surface roughness, of which the roughness contribution has no direct analytical expression. We show that through a control experiment on the same crystal in helium, the roughness contribution in hydrogen can be derived and the frequency shift due to the hydrogen mass uptake can be obtained. BIO: Dr. Tao Xu received his B.S. in Chemistry at East China University of Science and Technology, Shanghai, China in 1991, and his PhD in chemistry at The University of Alabama in 2003. He did a post-doc in chemistry at Texas A&M in 2003-2004 and a post-doc in materials science at Argonne National Laboratory in 2004-2006. ***************** 4.

WEEKLY MEMO, March 10, 2008 ENJOY SPRING BREAK! ***************** 1. ANNOUNCEMENTS ***************** 1.1: Alarm System Work, completed Friday, 030708: John Weaver send a ³thank you² for your patience during the work on the building alarm systems on Friday! The amount of interruption of the work in the building was far more significant than we expected, and I apologize for the intrusion on your research. The engineer from Honeywell, supplier of the system, was very thorough in his analysis of the system, but in being thorough he needed to set off far more alarms than expected. Please be aware that this was a one-time event we will not have to do this type of verification again. The alarm system is now upgraded to include all new materials in use in the facility, modifications were made to give us more alarm levels allowing us to be more proactive in our response and hopefully minimize future alarms, and the functions of all notification systems were verified. Again, thank you for your patience and John sends apologies for the unanticipated interruptions. ******************** 2.

E. Garay, Department of Mechanical Engineering, Materials Science, and Engineering Program, University of California, Riverside. ABSTRACT: Nanocrystalline ceramics display significantly different properties and behaviors than their microcrystalline counterparts, yet they have been difficult to produce in bulk sizes so that some of the underlying property-microstructure relations are not entirely clear. One technique that has proven effective for producing high quality material with very small grain sizes is based on the application of large current densities and mechanical pressures to consolidate nano-powders. After an overview of the processing method, I will discuss several nanocrystalline oxide materials that we have been working on for structural-optical and magnetic applications. Properties presented will include improved visible light transmittance, altered thermal and electrical conductivity and highly temperature dependent magnetization. The results will be discussed in terms of crystal length scale effects, grain boundary structure differences and proximity of nanoscale phases. SHORT BIO: Prof. Garay received his B. S. in Mechanical Engineering (1999), M.S. in Materials Science and Engineering (2002) and Ph.D. in Materials Science and Engineering (2004) all from the University of California, Davis. During his doctoral studies he also worked in the Physics Directorate of the Lawrence Livermore National Laboratory. In 2004 he was appointed assistant professor in the Bourns College of Engineering at UCR where his research focuses on advanced material processing and synthesis. His laboratory is equipped with state of the art material processing and testing equipment including high vacuum chambers, a PVD system, furnaces, tensile testers, hardness testers and a novel electric current consolidation apparatus. Recently Prof. Garay¹s interests have been in producing nanostructured materials with tailored properties for optical, electrical/magnetic and structural applications. He, his students and co-workers also conduct fundamental studies on material defects and electric current effects on material processes. In 2005 he received the Army Research Office Young Investigator Award (ARO-YIP) for research on nano-crystalline oxide materials. ********** 4.
