Please consider attending the following: MATERIALS ENGINEERING SEMINAR "Effect of Biofuel Impurities on the Hot Corrosion of Yttria-Stabilized Zirconia Thermal Barrier Coatings" By Jorge H. Ramirez-Velasco Purdue MSE Ph.D. Preliminary Exam Advisor: Professor Rodney W. Trice ABSTRACT Aircraft propulsion and industrial power generation have highlighted the critical role of gas turbines in modern society. Currently, components for these applications must withstand temperatures of at least 1400°C when operating within the combustor and the high-pressure sections of a gas turbine engine. With superalloys operating at its maximum capacity, ceramic multilayered materials systems known as thermal barrier coatings (TBCs) are employed as thermal and environmental protection. However, the introduction of biofuels into gas turbines applications have come with new challenges. The contaminants found in military and commercial biofuels are known to include oxides of alkali and alkaline earth metals and silicon oxides. Furthermore, while calcium-magnesium-aluminum silicates (CMAS) are typically ingested as particulate in middle-east theaters, the impurity list in biofuels includes the necessary elements to form CMAS without exposure to any specific environment. This is very significant as CMAS is particularly destructive for operating temperatures above its melting temperature (~1250°C), mainly reducing yttria-stabilized zirconia (YSZ) TBCs lifetimes. Thus, identification of the corrosive compounds product of the interaction of biofuel contaminants/thermal barrier coatings and a specific understanding of its adverse effect its mandatory to avoid premature failure of gas turbines. In the proposed work, solutions containing the impurities of interest are prepared and sprayed onto TBCs simulating the deposit of the impurities during combustion. Subsequently, the TBCs are subject to static and dynamic heating up to 1400°C and their microstructures evaluated. Date: Wednesday, February 28, 2018 Time: 12:00 P.M.

Judges needed for the Lafayette Regional Science and Engineering Fair- Friday 3/2/2018
by Coar, Stacey L 21 Feb '18

21 Feb '18

Hello Everyone, It's that time of year again... The Lafayette Regional Science and Engineering Fair is upon us! (Friday, March 2) We need lots of volunteer judges, as there are 500+ students from grades 5-12 from 20 area schools. As always, a complimentary buffet dinner in the South Ballroom Purdue Memorial Union (4:30-5:45 pm) will precede judging in Stewart Center (6-9 pm). Please note that the Judges Room has been moved from the Stewart Center to the South Ballroom of the Purdue Memorial Union. Top 10 reasons to judge science fair: 10) Free dinner 9) It looks great on your resume/CV 8) You might learn something (I do every year!) 7) You see some really strange projects ("How much cigarette smoke does it take to kill a plant?") 6) Kids say funny things 5) You get to relay the funny things said by kids to your friends afterwards 4) These projects are not the most sophisticated, so you will feel really smart :) 3) It's a great way to inspire young students and give back to the scientific community- They're extremely excited to talk to "real scientists"! 2) Free cookies/coffee during judging 1) All that excitement about science is contagious! Significant others can judge too! (Remember, this is kid-level science) If you are willing to serve as a Judge this year, please register online using the directions below: Please see the attached document for judging categories, which can be used to help you decide which sections you might want to judge. Click HERE<http://www.sefi.org/register/judgeform.php?r=3> and fill in your information. In the "area of expertise" box, please enter up to three categories from the attached sheet that you are willing to judge. If you served previously as a special panel judge and you'd like to do so again, you can indicate that as well. (If the link above doesn't work, you copy-paste this URL http://www.sefi.org/register/judgeform.php?r=3 into your browser to navigate to the SEFI registration site) You will not get a reply email, but you will be getting more information as the date draws near. If you would like to recruit your friends, family members, or lab mates, just give them the category information and direct them to the registration link. I hope you can make it! We have a record number of projects again this year and need all the experienced judges we can get. Please feel free to ask if you have any questions. Best Regards, Phillip Rushton (prushton(a)purdue.edu<mailto:prushton@purdue.edu>) 2018 Judge Coordinator and Dr. Cynthia Stauffacher 2018 Director
