To self-enroll in this Blackboard course, click here<https://mycourses.purdue.edu/webapps/blackboard/execute/viewCatalog?id=&typ…> . Also please read the lab access form thoroughly for lab specific requirements such as “billing information required” or “faculty permission needed.” **** Safety Updates to ARMS 2136 Sample Prep Lab **** Earplugs and fingertip protectors are now available for use in the grinding lab (ARMS 2136). These were installed thanks to student input regarding a possible noise hazard during certain machine operations. The earplugs dispenser is installed on the grey cabinet in the back corner of the lab; it is easily visible from the entrance to the lab. The fingertip protectors are in the green bins on top of the middle belt grinder. We encourage you to make use of these items; and we also encourage feedback as to how effective these may or may not be. **** PPE Reminder **** Physical and health hazards and the required PPE for each MSE lab space are posted on the lab’s main door. Required PPE typically includes impact-resistant safety glasses, long pants, closed-toed shoes, and, for CHP labs, a lab coat. To encourage PPE use, a “three-strike” infraction policy has been adopted, described below. For example, an infraction could be not wearing safety glasses in a lab space where safety glasses are required. · First infraction: warning email with supervisor copied · Second infraction: lab access temporarily suspended · Third infraction: lab access permanently suspended **** Equipment Reporting Reminder **** If you encounter a piece of broken equipment, or have any questions about a specific piece of equipment, you should contact a member of the MSE Technical Staff: · For general equipment (and associated checklists): Tim VanMeter<mailto:tcvanmet@purdue.edu>, Darren Pauly<mailto:dpauly@purdue.edu> · For mechanical testing equipment: Jenni Fifer<mailto:fiferj@purdue.edu> · For analytical (iLab) equipment: Talukder Alam<mailto:alam18@purdue.edu> **** Important Links and Contact Information **** · For general safety questions, concerns, and lab access issues: mse-safety(a)purdue.edu<mailto:mse-safety@purdue.edu> or speak directly to MSE Safety Officer Jenni Fifer<mailto:fiferj@purdue.edu> (ARMS 2207) · For iLab equipment training and issues: Talukder Alam<mailto:alam18@purdue.edu> (ARMS 2207) · Equipment/Safety/Consumables Reporting Form<https://purdue.ca1.qualtrics.com/jfe/form/SV_7QcGyO9IVMwWRPD?_ga=2.24554381…> · Purdue REM Researcher’s Guide<https://www.purdue.edu/ehps/rem/laboratory/researchers.html#cs2> (all new researchers should check this out) · ARMS general safety information<https://engineering.purdue.edu/Intranet/Groups/Facilities/ArmstrongHall> ****Jan/Dec Accidents, Near Misses, and Concerns **** * Grad student was cleaning the sink when they noticed black stuff and a weird smell in the sink. Grad student asked around and discovered that another researcher was likely pouring a strong acid with a powder down the drain. Per their report, He was filtering out particles ineffectively with a paper towel. They do not know what the substance was and the other researcher refused to answer when asked. * Senior design group was diluting concentrated sulfuric acid and a small amount (<5 mL) was spilled over the graduated cylinder used to measure it in the fume hood. One groupmate stayed behind to watch it while the other went to go find Jenni but could not find me so they found Darren and a grad student to help. They cleaned up by wiping it up with several paper towels and then putting those paper towels in a beaker full of water. This was all disposed of as waste in an appropriately labeled waste bottle. * A grad student was draining nickel alloy waste directly down the drain. Another student approached them saying that they did not believe that it was something that should be put down the drain. The student approached me for my opinion on the matter and we determined that based on the SDS, the waste should be disposed of as hazardous waste. * An undergrad reported a glass tip that appears to have broken on the gas compressor by the window. It was broke from being turned on with too much force all at once and then slipping away and hitting the side of cylinder. A grad student cleaned up the glass and put it in a sharps container. * A grad student became concerned that the surface grinder in ARMS 2136 may be a noise hazard. REM has done a noise hazard assessment for this area and determined that it is a borderline noise hazard. Further assessment will be done at a later date. For now, earplugs have been added to this lab.

Please consider attending the following: MATERIALS ENGINEERING SEMINAR "Towards Plasmonic-assisted Magnetization Switching" By Alan Hwader Chu Purdue MSE Preliminary Exam Advisor: Professor Ernesto E. Marinero ABSTRACT All-optical magnetization switching has been reported to be a viable way for achieving magnetization reversal in fs time scales. Among the mechanisms involved in such ultrafast, magnetization switching is the generation of large opto-magnetic fields by fs circularly polarized laser pulses. In this work, we seek to exploit plasmonic resonances at the interface between magnetic materials and plasmonic materials. The enhancement of the opto-magnetic field is obtained via the excitation of plasmons induced by laser pulses. Ideally, the magneto-plasmonic nanostructures should consist of magnetic films with strong Perpendicular Magnetic Anisotropy (PMA) and a plasmonic material with low optical losses. CoCrPt magnetic films and TiN plasmonic materials are chosen in this work as the components of the magneto-plasmonic nanostructures. CoCrPt films grown on TiN exhibit in-plane magnetization. This study aims to search for suitable ultrathin seed layers for the growth of CoCrPt films with strong PMA on TiN plasmonic materials. Suitable seed layers need to be no more than a few nm in thickness, as the generated opto-magnetic field is expected to be strongly decremented by the presence of a thick interlayer between TiN and CoCrPt. The optimal thickness of seed layers based on magnetic, optical, and opto-magnetic properties will be further explored. As shown in the preliminary results, the growth of CoCrPt films on (CoCrPt)Ta seed layers deposited on TiN exhibit PMA. Whereas PMA is weaker than that observed when CoCrPt is grown on thick Ta/Ru bilayers, the reported results pave the way for the growth of magnetic materials on photonic structures.

Seminar Notice for Luis Regalado Bermejo's Preliminary Exam. January 21, at 9:00 a.m., in ARMS 1021.

Please consider attending the following: MATERIALS ENGINEERING SEMINAR "Towards the Development of an In Vitro Electro-Magnetic (EM) Platform to Study Neural Mechanisms" By Luis Regalado Bermejo Purdue MSE Preliminary Exam Advisor: Professor Ernesto E. Marinero ABSTRACT Electro-Magnetic (EM) stimulation techniques such as Transcranial Magnetic stimulation (TMS) have shown promising results towards the treatment of neurodegenerative diseases, however, there is an incomplete understanding of the physical mechanisms responsible for said effects. Current advances in the study of EM stimulation have found evidence of cellular-level effects caused as a result of this stimulation that have the potential to relate them towards changes in internal neural mechanisms such as synaptic plasticity. However, to unambiguously establish correlation between EM stimulation, neuron response and synaptic processes, the development of new techniques is required to probe directly within neuron and at synaptic connections, the coupling of applied electric and magnetic fields with fundamental processes responsible for neuron response such as action potential and ionic transport processes. This may be achievable with the proposal of in vitro EM stimulation platforms that can stimulate neurons directly and measure their effects on quantifiable sources such as ionic potentials or genetic expression. In addition, the miniaturization of these techniques has the potential of optimizing parameters of interest such as the magnetic field intensity and frequency spike train delivery which may help improve current stimulation therapies. This platform has the potential for providing interesting approaches towards the study of neurons with the ability to stimulate cells in a non-invasive manner, allowing the integration of different characterization technique, and to provide direct measurements of factors that can be related to synaptic plasticity.
