1. Announcements
****************
 
1.1: All BNC cleanroom and laboratory users: The once a semester mandatory
safety and procedures meeting will be held March 19, 6:00pm, and March 20,
7:00pm, in Burton Morgan Room 121 – the large conference room on the first
floor.  Due to safety updates and information that must be provided to all
users of the BNC facilities, attendance at ONE of these two meetings is
required.  To accommodate schedules to the best of our abilities, we have
scheduled the meetings on Monday and Tuesday evening.  To retain your access
privileges to the cleanroom and/or laboratories, you MUST attend one of
these meetings.  Thank you for your cooperation.
 
 
1.2:  Equipment scheduling, billing, and logging for BNC Cleanroom: John Coy
announces that the Coral Software System will go online April 2, 2007 to
handle equipment scheduling, billing, and logging for the BNC cleanroom.
Coral will replace all paper billing sheets and the current reservation
system.  It is setup such that each user working on a project(s) can have
one or more accounts to charge equipment time against. Faculty members need
to complete an on-line web form in order to add students to the system.  The
web address is: 
 
https://engineering.purdue.edu/NANO/CORAL <file://localhost/NANO/CORAL>
 
The form will ask for:
Account name (i.e., NSF, DARPA, etc.)
Account number (i.e., old-style account numbers 521-1211-1234 or
OnePurdue-style account numbers 41040000 008000012345)
Account Code (constructed using your initials and 01-99; i.e., TDS01, TDS02)
 
For each student, input
a Project name (i.e., MEMS, CMOS)
accounts they can charge against.
 
Please have the form completed by March 21, 2007 so your students will have
access to the cleanroom starting April 2, 2007.
 
Contact John Coy with any questions (jcoy at purdue.edu; 43480)
 
 
1.3: Heads Up: Cleanroom Preventive Maintenance scheduled for May 1-2, 2007
 
A scheduled shut down of cleanroom operations for 48 hours to complete a
six-month preventive maintenance procedure will take place on Tuesday
(1-May-07) at 7:00AM through Wednesday (2-May-07) at 5:00PM.  Maintenance is
required for our cleanroom makeup air handlers, chemical exhaust, and ultra
pure water systems.  Please note that the ultra pure water will be shut down
for the entire building.  We will also complete cleanroom troubleshooting to
improve temperature repeatability during this time.
 
Since the chemical exhaust system will be shut down please remove chemicals
from all hoods in the cleanroom prior to the shutdown.  If not, lab staff
will dispose of them for you.
 
Thank you for your understanding and patience during this necessary
procedure.  If you have any questions or concerns, please contact MARK
VOORHIS, 43036; mvoorhis at purdue.edu.
 
 
1.4: Visitor Safety Glasses: a new program per John Weaver and Ira Young.
New safety glasses have been purchased and distributed for use by visitors
coming into the laboratories.  To distinguish them from the regular safety
glasses that normal occupants of the laboratories use, we purchased brightly
colored (red, white, blue) glasses.  These are for VISITOR use only — please

3.1: “Piezoelectric Transducers – Strain Sensing and Energy Harvesting,” by
Toshikazu Nishida, Interdisciplinary Microsystems Group, Department of
Electrical and Computer Engineering, U of Florida, March 19, 11:00, BRK 2001
 
Acoustic pressure or mechanical force sensing via piezoelectric coupling is
closely related to the harvesting of electrical energy from acoustical and
mechanical energy sources.  In this talk, mesoscale and microscale
piezoelectric transducers for acoustic and vibrational sensing and energy
harvesting will be discussed.  For example, a micromachined piezoelectric
microphone has been developed for aeroacoustic applications with a
demonstrated sensitivity of 0.75 μV/Pa, a dynamic range greater than six
orders of magnitude (47.8 - 169 dB, ref. 20 μPa), and a resonant frequency
of 50.8 kHz.  In addition, acoustic energy harvesting has been demonstrated
using a mesoscale (~ 2 cm) Helmholtz resonator machined in aluminum,
delivering 25 mW to a resistive load at a sound pressure level (SPL) of 152
dB (ref. 20 μPa). This acoustic energy may be used to locally power a
wireless active liner for suppression of engine noise in turbofan engines,
where acoustic levels typically reach up to 150 dB. For space-constrained
applications, a micromachined acoustic energy harvester was also recently
developed. It employed a silicon-micromachined, circular, piezoelectric
composite diaphragm.  Experimental results indicated a maximum output power
density of 0.34 μW/cm2 at 149 dB (ref. 20 μPa) and a potential output power
density of 250 μW/cm2 with an improved fabrication process.  Similar
examples will be given for cantilever-based vibrational energy harvesters.
Finally, some system considerations will be discussed for energy
harvesting-powered systems.  As the volume of the energy harvester is
reduced, as expected, the harvestable power decreases given a specific power
density for the available ambient conditions and  material parameters. For
system designs, the power balance between average power dissipation and
average power harvesting determines the maximum duty cycle possible under
specific energy harvesting conditions.

3.2: NCN/INAC Tutorial Lecture: “Nanoscale Antenna Apertures,” by Xianfan
Xu, Professor, School of Mechanical Engineering, Purdue University,
Wednesday, March 21, 2:00PM, EE 317
 
ABSTRACT: This presentation will discuss light concentration and enhancement
in nanometer-scale ridge aperture antennas.  Resent research, including
numerical simulations and near field optical measurements has demonstrated
that nanoscale ridge antenna apertures can concentrate light into nanometer
domain.  More importantly, these ridge antenna apertures also provide
enhanced optical transmission several orders of magnitude higher than
regularly shaped nano-apertures.  We will discuss fundamental theories of
ridge antenna apertures, finite-difference time-domain (FDTD) calculations
for optimizing the design of these antenna apertures, and near field
scanning optical microscope (NSOM) measurements of the near field intensity
distribution of the light transmitted through these apertures. It is shown
that the nanoscale antenna apertures can produce a concentrated light spot
beyond the diffraction limit with enhanced transmission.  Potential
applications of these nanoscale aperture antennas include nano-lithography
and nano-imaging.

3.3: “CMOS-Nano Hybrid Technology: A nanoFPGA-related study,” by Dr. Wei
Wang, Electrical and Computer Engineering, IUPUI, Wednesday, March 21,
3:30PM, POTR 234 (Fu Room) [Refreshments at 3:00PM]
 
ABSTRACT: The future of the hundred billion dollar semiconductor industry
relies on radical innovations of nanoelectronics.  Instead of completely
replacing CMOS technology, the non-conventional nanotechnologies are
expected to be hybrid with the CMOS systems. The CMOS-nano hybrid technology
tries to utilize the advantages of both traditional CMOS and novel
nanowire/nanotube devices, which will enhance IC performances in the near
future and create breakthroughs in the long run. In this talk, based on
hybrid technologies, new interconnections, devices, and reconfigurable
structures will be discussed with respect to future FPGA design
technologies.

3.4: RCHE Brownbag Lunch Series: “Engineering a Policy-Based System for
Federated Healthcare Databases,” by Arjmand Samuel, Electrical and Computer
Engineering, Purdue University; March 23, 11:30, MRGN 206
 
ABSTRACT: Policy-based systems for federated healthcare systems have
recently gained increasing attention due to strict privacy and disclosure
rules. While the work on privacy languages and enforcement mechanisms, such
as Hippocratic databases, has advanced our understanding of designing
privacy-preserving policies for healthcare databases, the need to integrate
these policies impractical healthcare framework is becoming acute.
Additionally, while most work in this area has been organization-oriented
dealing with exchange of information between healthcare organizations (such
as referrals), the requirements for the emerging area of personal healthcare
information management have so far not been adequately addressed. These
shortcomings arise from the lack of a sophisticated policy specification
language and enforcement architecture that can capture the requirement for
(i) integration of privacy and disclosure policies with well-known
healthcare standards used in the industry in order to specify the precise
requirements of a practical healthcare system, and (ii) provision of
ubiquitous healthcare services to patients using the same infrastructure
that enables federated healthcare management for organizations. In this
paper, we have designed a policy-based system to mitigate these concerns.
One, we have designed our disclosure and privacy policies using a
requirements specification based on a set of use cases for the Clinical
Document Architecture (CDA) standard proposed by the community. We have
shown that our policy specification language is effective in terms of being
able to handle the most common use cases. Two, we present a context-aware
policy specification language that allows encoding of CDA-based requirements
use-cases into privacy and disclosure policy rules. Our language enables
specification and enforcement of privacy-aware access control for federated
healthcare information across organizational boundaries, while the use of
contextual constraints allows the incorporation of user and environment
context in the access control mechanism for personal healthcare information
management. Moreover, the declarative syntax of the policy rules makes the
policy highly reconfigurable and adaptable to changes in privacy regulations
or patient preferences. We also present an enforcement architecture for the
federated healthcare framework proposed in this paper.
 
 
3.5: Materials Science and Engineering Seminar: “Damage to Concrete by
Crystallization of Ice,” by George W. Scherer, Princeton University, Friday,
March 23, 3:30; MSEE B012
 
ABSTRACT: Frost damage to concrete has been attributed to hydraulic
pressure, resulting from the increase in volume as water transforms to ice,
and to crystallization pressure exerted by ice confined in mesopores.  We
will discuss the evidence for each mechanism, and examine the circumstances
under which one or the other may predominate.  The role of crystallization
pressure is clear in dilatometric experiments showing contraction of
air-entrained concrete during freezing, as ice in larger pores sucks liquid
from the surrounding mesopores, and the negative pore pressure induces
shrinkage of the body.
         If the temperature is low enough to permit the ice to propagate
through the pores, the release of heat of fusion raises the temperature of
the water toward the melting point, which results in the formation of
dendrites.  The nature of dendritic growth in a porous medium is different
from that in a free liquid, because the size of the dendrite and its radius
of curvature are strongly influenced by the pore structure.
         A different type of damage occurs when a layer of ice forms on the
surface of concrete, such as a sidewalk.  The familiar damage pattern, which
exposes the aggregate in the concrete, shows a mysterious dependence on the
concentration of deicing salt: there is no damage if there is no salt in the
water, or if there is a lot (> 5%), but the damage is severe at
concentrations around 3%. This behavior can be understood in terms of the
fracture mechanics of ice.
 
BIO: George W. Scherer received his BS and MS degrees in 1972 and his PhD in
materials science in 1974, all from MIT, where his thesis work was on
crystal growth in glass. From 1974 to 1985, he was at Corning Glass Works,
where his research included optical fiber fabrication, viscous sintering,
and viscoelastic stress analysis. The latter work was the subject of his
first book, Relaxation in Glass and Composites (Wiley, 1986). From 1985
through 1995, he was a member of the Central Research Dept. of the DuPont
Company, where his work dealt principally with sol-gel processing, and
especially with drying. In collaboration with Jeff Brinker of Sandia
National Labs, he wrote a book entitled Sol-Gel Science (Academic Press,
1990). In addition, he is the author of ~220 papers on glass, sol-gel
science, and cementitious materials, and holds 10 US patents.
         He has received the Morey, Purdy, Brunauer, and Sosman Awards from
the ACerS, and the Iler Award from the American Chemical Society. In 1997 he
was elected to the National Academy of Engineering.
         In February, 1996, he became a full professor in the Department of
Civil & Environmental Engineering at Princeton University, and a member of
the Princeton Materials Institute. His research involves mechanisms of
deterioration of concrete and stone, particularly by crystallization of ice
and salts in the pores.
