ISP Recertification of our School
by Nagy, Gabriela 29 Apr '24

29 Apr '24

Hello Everyone, I am pleased to let you know that following the Integrated Safety Plan (ISP) recertification meeting with REM representatives on Monday, March 25, 2024, followed by safety inspection of selected ChE labs and corrections of identified deficiencies, our School was ISP recertified for another year. The official recertification document was signed on April 24, 2024, and made available to me over the weekend. Thank you for your efforts in making this possible and for your sustained commitment to safety! Sincerely, Gabriela on behalf of ChE Safety Committee __________________ Gabriela Nagy, PhD Industrial Education Director Davidson School of Chemical Engineering Room FRNY G051 Purdue University Tel: (765)-496-1710 E-mail: nagyg(a)purdue.edu<mailto:nagyg@purdue.edu>

ChE Safety Committee Openings for Graduate Students
by Nagy, Gabriela 24 Apr '24

24 Apr '24

Hello Everyone, Two of the current graduate student members of the ChE safety committee (Melissa Marsing and Dharini Varadharajan) have served for nearly two years on the safety committee and I want to take this opportunity and thank them for all their help and input as committee members; they have been very active and valuable members of our committee. I also want to thank Catherine Vincent for her service and contributions; Catherine represented the GSO on the safety committee for 18 months. We are looking forward to working with the next GSO safety officer once results of GSO elections are announced. The ChE Safety Committee has now two (2) openings for graduate students. We are looking for enthusiastic, motivated and safety oriented graduate students to join our active safety committee. An ideal candidate is someone who still has to complete about 3 years of graduate studies and who performs research in a lab. Typically, graduate students serve on the ChE Safety Committee for a period of two years. We would like the new members to join us this summer (July 2024), as trainees, and then with full responsibilities from August 2024. Some of the Safety Committee members responsibilities are: * attend the safety committee meetings (once a month) and actively participate in discussions and committee activities * report unsafe conditions and unsafe practices/acts * assist in addressing safety issues/concerns * contribute with ideas and suggestions for improvement of safety in our School * follow safety procedures and rules and be an example for others for work safely * help with the safety inspections throughout the year, and with preparations for the ISP Recertification Review with REM * help investigating safety incidents, if/when necessary * share safety information with colleagues, etc. For a more detailed description of the role please see this document: Responsibilities of graduate student members of the ChE Safety Committee<https://engineering.purdue.edu/ChE/aboutus/safety/documents/2023-05-11-Resp…> If you know someone who you think would be a good member of the safety committee, or if you feel this would be a good fit for you, please send your nomination or intent to join, and a short supporting statement/justification describing why you or your nominee should be considered for this opening, by email to: Gabriela Nagy: nagyg(a)purdue.edu<mailto:nagyg@purdue.edu>, by 5 pm on Monday, May 13 , 2024. I look forward to receiving your emails! Thank you, Gabriela on behalf of ChE Safety Committee __________________ Gabriela Nagy, PhD Industrial Education Director Davidson School of Chemical Engineering Room FRNY G051 Purdue University Tel: (765)-496-1710 E-mail: nagyg(a)purdue.edu<mailto:nagyg@purdue.edu>

Further information can be found below. [cid:image001.jpg@01DA8118.6C280050]<https://maillinks.purdue.edu/t/45922180/1710281286/79579849/0/1006672/?x=27…> Dr. Hansol Wee Post-Doctoral Research Associate Davidson School of Chemical Engineering Purdue University Bio: After receiving his Bachelors of Science degree in Chemical Engineering from Sogang University in 2014, Dr. Hansol Wee continued on in the same department to receive his Master of Science degree in Chemical Engineering under the guidance of Professor Won Bo Lee (now at Seoul National University). He then obtained his PHD under the guidance of Professor Osman Basaran at Purdue University in 2023. "Effects Of Surface Viscosity On Breakup Of Liquid Threads" April 4, 2024 Seminar: 3:00 p.m. - 4:15 p.m. ET FRNY G140 - Reception at 2:30 p.m. in FRNY Atrium - Abstract: Free surface flows exhibiting hydrodynamic singularities are ubiquitous in technology, daily life, and nature. Examples of such flows include dripping faucets, inkjet printing in both industrial and personal settings, drop-by-drop manufacturing, microarraying, crop spraying, atomization or spray coating, fuel injectors, as well as natural occurrences like fountains and waterfalls. Additionally, they are encountered during the usage of numerous consumer and household products like paints, cleaners, cosmetics, drugs, and foods. After giving a quick overview of the current understanding of pinch-off singularities which arise during the breakup of liquid drops, jets, and threads, the majority of the presentation will be devoted to the role of surface-active additives on pinch-off. Surfactants residing at fluid interfaces not only reduce and induce gradients in surface tension but can also induce additional surface rheological or viscous effects in response to dilatational and shear deformations. Both surface tension and surface viscosities are dependent on surfactant concentration. While the measurement of surface tension and its effects on interfacial flows have become standard practices, determining surface viscosities remains notably challenging. This challenge persists because existing measurement methods often fail to isolate the effects of surface viscous stresses from those attributed to Marangoni stresses. Consequently, the quantitative characterization of surface viscous effects in interfacial flows remains arduous. To address this difficulty, a combined asymptotic and numerical analysis is presented for the pinch-off of a surfactant-covered Newtonian liquid jet. Asymptotically exact solutions derived from slender-jet theory and numerical solutions of the full three-dimensional but axisymmetric (3DA) equations are provided for jets with and without surface rheological effects. The analysis reveals that Marangoni stresses become negligible near pinch-off compared to other forces. Furthermore, it demonstrates that the rate of jet thinning is significantly reduced by surface viscous effects. Simple analytical formulas for inferring surface viscosities are derived from the dynamics near the pinch-off singularity, offering straightforward means for measuring surface viscosity. 3DA simulations confirm the validity of the asymptotic analyses.
