From: elist39-bounces(a)lists.purdue.edu [mailto:elist39-bounces@lists.purdue.edu] On Behalf Of List 39 Administrator Sent: Wednesday, August 12, 2015 11:01 AM To: elist39(a)purdue.edu; elist39d(a)purdue.edu Subject: [Elist39] Traffic and student move-in [Purdue University] TO: Executive Vice Presidents, Chancellors, Vice Presidents, Vice Chancellors, Vice Provosts, Deans, Directors and Heads of Schools, Divisions, Departments and Offices FROM: Frank Dooley, vice provost for teaching and learning DATE: August 12, 2015 RE: Traffic and student move-in As you all are certainly aware by now, Interstate 65 in Tippecanoe County is causing challenging traffic issues for those traveling to or around Purdue. Soon, more than 40,000 students will be arriving on campus, further compounding the issue. Purdue is working to alert all students via email and social media of the Interstate closure and advising them to plan ahead, expect delays and be as patient as possible while state, area, local and Purdue law enforcement work to assist traffic in every way possible. As a reminder, Purdue's West Lafayette students attending Boiler Gold Rush will move into their on-campus housing on August 17-18, a Monday and a Tuesday, accommodating a shifted Boiler Gold Rush schedule designed to improve student engagement and connect orientation more closely to the start of the academic term. Boiler Gold Rush will take place August 19-22. Residence hall contracts for returning students begin Friday, August 21. The first day of classes is August 24. During the move-in days, the central campus area will experience heavy traffic that may cause delays or disruptions to normal business. The most-affected areas will include State Street from Martin Jischke Drive to Airport Road; Stadium Avenue between Northwestern Avenue and McCormick Road; Martin Jischke Drive from State Street to Stadium Avenue; Third Street from Martin Jischke Drive to McCormick Road and all side roads in the vicinity of residence halls. On August 18, the new student induction event will take place at 4:00-4:45 p.m. in Mackey Arena. Before and after that period, about 6,000 undergraduate students and 6,000 parents will be walking from the residence halls areas to the arena, then returning to the halls and parking areas. It is important for employees to anticipate delays and give themselves additional time for their morning commutes and/or to travel around campus for meetings during these periods. At the same time, I hope that departments and supervisors will exercise discretion and an extra degree of understanding if the additional activity during the workday causes unavoidable delays for workers. Additional information about the Boiler Gold Rush, move-in and how it will affect those on campus is available online at www.purdue.edu/bgr<http://www.purdue.edu/bgr>. Those with immediate questions should contact Dan Carpenter, director of student success, at dwcarpen(a)purdue.edu<mailto:dwcarpen@purdue.edu>.

Aaron Harrison Dissertation Defense, Thursday, August 13th, at 1:30 p.m. in FRNY 3062B
by Green, Corwin S 06 Aug '15

06 Aug '15

This e-mail is to announce that Aaron Harrison will be defending his dissertation, Detailed Investigations of Capillary and van der Waals Forces in the Adhesion between Solids, on Thursday, August 13th, at 1:30 p.m. in FRNY 3062B. The dissertation is directed by Dr. Beaudoin, and the abstract is below. All are welcome to attend. Abstract: The primary focus of this dissertation is on characterizing two fundamental forces common to adhesion between solids: capillary and van der Waals forces. These two forces have a significant impact on how solids flow, stick to surfaces, agglomerate and break; therefore, understanding their behavior can lead to better processing techniques. Capillary forces are responsible for caking in the food, cosmetic, and pharmaceutical industries and are caused by the spontaneous formation of liquid bridges between two surfaces in close contact. To better understand how capillary forces depend on the system relative humidity (RH), solid surface separation, and surface hydrophilicity, the Wang-Landau Monte Carlo technique on a lattice-gas framework has been used. For a smooth, hydrophilic AFM tip against a flat, hydrophilic plate on a 45x45 lattice, a maximum capillary force occurs when the separation distance is one molecular diameter of the adsorbate and the capillary force decreases as the separation distance increases, except when the tip and the surface are in contact. The capillary forces associated with completely wetting AFM tips are strongly dependent on the system RH, while partially wetting and partially drying tips are relatively independent of RH. Interestingly, capillary forces can be significant in low RH environments and thus cannot be ignored in AFM studies involving hydrophilic surfaces. Another aspect in predicting capillary forces involves the use of the Kelvin equation, which describes the relationship between the system saturation and the curvature of the liquid-vapor interface. Using a two-dimensional lattice-gas model with mean-field density functional theory, the effect of meniscus curvature on the prediction of the Kelvin equation has been studied. First, the dependence of the surface tension on the curvature of the liquid-vapor interface is established for critical bubbles forming within a bulk liquid. It is demonstrated that for a pure-component, bulk system the Kelvin equation properly describes the curvature of the interface at the Gibbs surface of tension, even for very small bubbles. Next, the system is modified to include parallel, hydrophilic surfaces between which capillary bridges can form. The curvature of these capillary bridges is quantified at differing saturation levels, separation distances and contact angles and then compared to the Kelvin equation. For these capillary bridges, it is found that the radius of curvature is not constant (i.e., the meniscus is not circular) and that the Kelvin equation is a non-physical extrapolation as the system approaches zero saturation or as the separation distance decreases. Therefore, the Kelvin equation best describes curvatures for pure-component systems or for capillary bridges that are near or at saturation and with large plate separations. Dry adhesion caused by dipole-dipole interactions (i.e.,van der Waals forces) have also been considered. The Hamaker constants (which are a measure of the van der Waals forces) and dispersive surface energies have been characterized for ten energetic powders using inverse gas chromatography. It has been determined that the effect of the amount of fuel additives in the energetic powders on Hamaker constants is not statistically significant. In addition, the Hamaker constants agree with Lifshitz theory indicating that inverse gas chromatography is a possible alternative for characterizing the dry adhesion of powders. Lastly, when combined with a better prediction of capillary forces, these experimentally determined Hamaker constants can lead to better models describing the removal of these energetic materials. Finally, an ancillary project investigating the nanoscopic, chemical properties of crystalline griseofulvin embedded in polymer is also included in this dissertation. Obtaining small-scale chemical information from traditional infrared (IR) spectroscopy has recently been improved from 3-30 μm to 10-100 nm by combining atomic force microscopy (AFM) with IR and is known as AFM-IR. It is shown that AFM-IR can chemically distinguish drug nanoparticles embedded in polymer with a sub-100 nm resolution, which is a considerable improvement over traditional IR techniques.
