"Quantum Information in Nanoelectronics"
Charles Marcus, Professor of Physics and Director of Center for Nanoscale Systems
LISE 303

Join us for an overview of current research directions in the Marcus lab, including: electron phase coherence in quantum dots; coulomb blockade effects; experiments in quantum chaos;  coherence effects in carbon nanotubes; spin effects in mesoscopics; experimental schemes for quantum computing, and quantum information processing in the solid state.

"Water, Energy and Life: Fresh Views from the Water's Edge"
Gerald H. Pollack, PhD
Professor of Bioengineering, University of Washington
LISE 303

Photons from ordinary sunlight, may have an unexpectedly powerful effect that goes beyond mere heating. It may be that solar energy builds order and separates charge between the near-surface exclusion zone and the bulk water beyond - the separation creating a battery. The resemblance to photosynthesis is evident. Indeed, this light induced action would seem relevant not only for photosynthesis but also for all realms of nature and engineering involving water and interfaces, including chemistry, biology, physics and nanotechnology.

"Scanning Microwave Microscopy"
Gilbert Min, Ph.D., Agilent Technologies
Northwest Building Room 205
The new scanning microwave microscopy (SMM) platform enables the simultaneous measurements of AFM data and traditional microwave network analysis.  SMM measures the electrical properties of a material (i.e. dielectric properties, capacitance, and complex impedance), providing researchers in polymer science, semiconductors, and bioscience a new analytical tool for advancing research. This presentation will describe these nano measurement tools, followed by an example of SMM implementation, and an explanation of the technical challenges in developing this new technology.

"Multiple Nuclear Polarization States in a Double Quantum Dot"
Professor Jeroen Danon, Kavli Institute of Nanoscience, Delft University of Technology
Lyman 425
Abstract: We observe multiple stable states of nuclear polarization in a double quantum dot under conditions of electron spin resonance. The stable states can be understood within an elaborated theoretical rate equation model for the polarization in each of the dots, in the limit of strong driving. This model also captures unusual features of the data, such as fast switching and a 'wrong' sign of polarization. The results reported enable applications of this polarization effect, including manipulation and control of nuclear fields.

NNIN Program Renewed for Five more Years
NNIN at HarvardCNS was recently notified that it's National Science Foundation National Nanotechnology Infrastructure Network (NSF-NNIN) program has been renewed for five more years and will be awarded $4 million.  Through this program CNS currently supports 600 on-campus researchers and serves as a regional facility for 400 off-campus researchers from both academic and industrial sectors.

New Incident Report Form
Our best days in the laboratory are those when things go well and experiments are accomplished efficiently and safety.  But sometimes things don't go well.  Now both CNS lab users and staff members have a tool to document those times when things don't go as planned.  The Incident Report form should be completed by anyone who observes an unsafe condition including behavior, equipment problems, and building issues.  Bring completed forms either to the CNS administrative office in LISE 306, or drop off at the LISE EHS office "suggestion box" outside G56.


Updated
Material Request Form
The CNS Chemical Request form is familiar to anyone who has brought special chemicals into the laboratories.  Now this form has been modified to  screen more potential contamination sources, including
biological and nanoparticle
materials.  Users needing to bring such materials into the labs must now complete this form and submit to the Admin office for EHS approval.  See the form for instructions.
