Andy Koswara Dissertation Defense, Friday, July 11th, at 1:00 p.m. in FRNY 3062B

This e-mail is to announce that Andy Koswara will be defending his dissertation, Robust and Multiobservable Evolutionary Control of Quantum Dynamics, on Friday, July 11th at 1:00PM in FRNY 3062B. The dissertation is being directed by Dr. Varma, and the abstract is below. All are welcome to attend. Abstract: Advances in quantum control theory and optimization techniques have made possible a new phenomenon of quantum engineering. Chemical reactions can now be dynamically manipulated using first-principle quantum chemical models, in which a laser field, rather than a catalyst, serve as photonic reagents to selectively break a chemical bond and yield products via intramolecular rearrangement. A field pulse may also be designed to perform ultrasensitive spectroscopy, where compounds with very similar chemical properties are differentiated through their unique interaction with resonant and off-resonant photons. Despite significant progress in theoretical and laboratory quantum control, however, quantum engineering remains principally challenging due to manifestation of noise and uncertainties associated with the input and system parameters. Specifically, a small magnitude of variation in the field and Hamiltonian parameters would cause an otherwise optimal field to deviate from controlling desired quantum state transitions and reaching a particular objective. Thus, an accurate analysis of robustness of controlled quantum dynamics followed by a robust control framework is essential in achieving quantum control in a practical setting. In this work, theoretical foundations for quantum control robustness analysis are presented from both a distributional perspective - in terms of moments of the transition amplitude, interferences, and transition probability - and a worst-case perspective. In addition, an evolutionary control strategy for achieving robust control via open- and closed-loop approach are described with its mechanism of convergence elucidated using the robustness analysis method.

Haroan Yang dissertation defense tomorrow (Tuesday 7/1) at 10:00 a.m. in GO60A

This e-mail is to announce that Haoran Yang will be defending his dissertation, Nanostructured Thermoelectric Materials Based on Solution Phase Synthesis: Towards Efficiency and Sustainability, tomorrow (Tuesday 7/1) at 10 a.m. in FRNY GO60A. The dissertation is being directed by Dr. Wu, and the abstract is below. All are welcome to attend. Title Nanostructured Thermoelectric Materials Based on Solution Phase Synthesis: Towards Efficiency and Sustainability Abstract Thermoelectric devices fulfill the direct conversion between heat and electricity, which have many potential applications including waste heat harvest, solar thermoelectric power generation, solid state cooling, and etc. However, it is a challenge to develop materials with superior performance that allow the practical uses of thermoelectric technology. Recent progresses in nanostructured thermoelectric materials have shown great potential in the enhancement of thermoelectric figure of merit ZT. Meanwhile, it is equally important to consider the sustainability of thermoelectric technology, which should satisfy many features such as low-cost, energy-efficient, scalable, and pollution-free. In the present study, we aim at both the efficiency and sustainability in the development of nanostructured thermoelectric materials. We explore the feasibility of using solution phase synthesized nanostructures as the building blocks for the fabrication of high-performance thermoelectric materials, and then extend our research on some of the sustainability issues. Firstly, we show that composition modulation can be used to control the doping level in Ag2Te nanowires, which yield nano-grained samples with enhancedZT. Secondly, we demonstrate that a novel kind of dumbbell PbTe-Ag2Te heterostructures can be synthesized with wet chemistry, and a complex nano-inclusion-in-matrix structure can be achieved correspondingly, which mimics similar structures fabricated by melt synthesis that have been proven to be successful, and gives rise to a further enhancement in ZT. Thirdly, we studied the possibility to replace the hazardous chemical hydrazine with a green chemical ascorbic acid in the synthesis, and we show that various metal telluride nanowires can be synthesized including Ag2Te, Bi2Te3 and etc. Finally, efforts have been made seeking for novel thermoelectric materials contain only non-toxic and earth-abundant materials, and as a proof-of-concept study, Cu2ZnSnS4 nanocrystals based thermoelectric properties are investigated. The results suggest the bottom up approach toward nanostructured thermoelectric materials based on solution phase synthesis is of great potential. Not only simple nano-grained materials but also some more complex heterogeneous structures can be achieved with this approach. With proper control over the composition, these samples exhibit enhanced ZT. Moreover, the complex structures also provide an ideal platform to study the newly proposed energy filtering effect, which could enhance the thermoelectric power factor. The study on the sustainability has made progressed on “greener” chemistry for the synthesis of nanostructured thermoelectric materials. The searching for novel thermoelectric materials with environmental benign composition and cheap elements, although is still in the preliminary stage, stands for the future direction.

Results of safety inspections - June 2014
by Nagy, Gabriela 19 Jun '14

19 Jun '14

Hello Everyone, In preparation for the upcoming Safety Recertification of our School with REM, the ChE Safety Committee inspected last week all laboratories and offices in FRNY and the rooms occupied by ChE personnel in POTR. I am glad to report that we noticed an overall improvement in the safety of our labs. Please find attached a document that summarizes the he most frequent safety issues identified during the safety inspections. The document also spells out the OSHA and Purdue required documentation, PPE requirements and a reminder of some safety rules and policies applicable to our School. Please pay close attention to the safety gloves policy under the PPE section. It was brought to my attention that this safety rule is not always followed by our graduate students. As a reminder, safety gloves are not permitted on the corridors. Each faculty or person responsible for a specific area will shortly receive another email with the results of the safety inspection for that area, please address the problems identified. The Safety Committee will perform unscheduled inspections at the end of July to check whether the safety issues identified were addressed. Thank you all for your continuous commitment to safety! Best regards, Gabriela Nagy on behalf of the ChE Safety Committee ________ Gabriela Nagy, PhD Industrial Education Director ChE Safety Committee Chair School of Chemical Engineering Room FRNY G051 Purdue University Tel: (765)-496-1710 E-mail: nagyg(a)purdue.edu<mailto:nagyg@purdue.edu>

Safety incidents in FRNY
by Nagy, Gabriela 17 Jun '14

17 Jun '14

Hello Everyone, I would like to share with you two recent safety incidents in our School: 1. May 21, 2014: When a small amount of dry Pd/C was added to a flask containing methanol, a small flame was observed near the neck of the flask. The flame was instantaneous and disappeared quickly. No people were injured during this incident. To avoid this happening in the future, the procedure of mixing catalyst (Pd/C) with alcohol was modified to be performed under inert atmosphere. This measure was taken after identifying that the catalyst is most susceptible to rapidly ignite the vapors of lower alcohols (such as methanol). In the presence of air, many organic vapors that readily ignite can undergo combustion violently, but having the above procedure performed in inert atmosphere eliminates this hazard. 2. June 2, 2014: When taking the glassware out of the sink after washing, a piece of glassware dropped on the floor and broke. A fragment of broken glass bounced back and cut the researcher's hand. The lacerations to the hand caused by the broken glass were treated in the emergency room. The patient was discarded shortly after his wounds were cleaned and no further medical attention was needed. I hope that sharing this information with you will prevent similar situations occur in our labs.

FW: Interior windows in FRNY
by Valley, Jeffrey L 06 Jun '14

06 Jun '14

BE ADVISED- FYI.................................if you have any questions please contact me. Thank you. From: Scott, Vivian A Sent: Friday, June 06, 2014 1:01 PM To: Valley, Jeffrey L Cc: Clark, Kristal S; Brooks, Daniel A Subject: Interior windows in FRNY Hi Jeff, Building Services plans to provide interior cleaning of EXTERIOR windows this summer, as our resources allow. We plan to start in FRNY on Tuesday morning (6/10) and will work our way around to the rooms that have exterior windows. This should include all rooms that have blinds, or windows to the outside. It doesn't include things like door glass, or interior walls made of glass. The cleaning will take place between the hours of 7:30AM and 4:00PM, Monday - Friday. The door to each room will be left as we find it: if locked, we will lock it again when we leave. If unlocked, we will leave it unlocked. If you could please have all items removed from the window sills, that would be very much appreciated. We can't clean windows that have obstacles in front of the glass. If our crew members (Alex, Laura, and Juvenal) arrive to clean a window and the occupant doesn't want them cleaned, we will pass on to the next room. Will you notify the building occupants please so they will be prepared for our visit? Kristal Clark is the contact person for this project. Please know her know if you have questions or concerns. Her contact info is: kmuse(a)purdue.edu<mailto:kmuse@purdue.edu>. Her office phone number is: 494-7110. Thank you, Vivian Scott Day General Manager Purdue University Building Services scottv(a)purdue.edu<mailto:scottv@purdue.edu> Phone: 494-7116 How are we doing? - Building Services<https://purdue.qualtrics.com/SE/?SID=SV_8IV3f4oryRKVi8Q>
