A ceremony that dedicated a new fast scanning confocal microscope, which was purchased through the generosity of Dr. Ken Young ’72, was an opportunity for some 1972 classmates to visit the Department of Physics. This event, along with Prof. Gene Mele’s ’72 seminar, attracted several of our alumni including Dr. Jim McGroddy ’58, who sponsors The McGroddy Frontiers in Science Seminar Series, his wife Bonnie, Dr. Richard Kelly ’59, Sebastian Hurtado Parra ’15, and others. It was a great opportunity for our current majors to interact and chat with our alumni.

Our student will use the confocal microscope in their upper level physics courses and research. Laser scanning confocal microscopy is an essential tool in biological, biochemical, and biomedical sciences. It plays a similar role to scanning electron microscopy in materials science. Moreover, confocal microscopes can be used to perform pseudo-infinite depth of field imaging without the need for a vacuum system, topographic imaging, luminescence imaging, and Raman spectroscopic imaging, just to name a few applications. These and other capabilities make confocal microscopy a versatile addition to the Concentration in Materials Science curriculum as a novel technique of materials science characterization toolkit.

Prof. Eugene Mele, SJU class of 1972 (Physics), visits SJU

March 27, 2019

On March 20th Prof. Eugene Mele, SJU class of 1972 (Physics), was a speaker for the McGroddy Frontiers in Science Seminar Series and delivered a talk entitled “Topological Insulators: Mind the Gap”. The seminar addressed questions such as: What is a topological insulator? What is its relation to the iconic warning posted on the London tube? And how about Brexit? Prof. Mele’s talk gave an introduction to topological quantum states of matter, explained why they are important and offered at least a guess at how they might be used.

Prof. Mele is the 2019 recipient of the Breakthrough Prize in Fundamental Physics along with his colleague Prof. Charlie Kane, both of the Department of Physics and Astronomy at University of Pennsylvania.

Students Present at the Mid-Atlantic Soft Matter Workshop

February 18, 2019

Four of our students, Martyna Habdas ’20, Michael Jenkins ’19, Francis Snyder ’21, and Rui Zhang ’18, gave oral presentations on February 15 at a regional workshop on soft matter held at the Institute for Bioscience & Biotechnology Research.

Students Inducted into the Scientific Research Honor Society

April 2, 2018

Three of our students, Rui Zhang ’18, Miranda Mazzio ’18, and Thomas Buerkert ’18, were inducted into Sigma Xi Scientific Research Honor Society.  Sigma Xi is a research honor society for scientists and engineers founded in 1886 at Cornell University by a junior faculty member along with a few graduate students.  Members are elected on basis of their research achievements.  Congratulations!

Miranda Receives the Nicholas and Susan Nicolaides Research Fellowship

Congratulations to Miranda Mazzio!  Miranda received the Nicholas and Susan Nicolaides Research Fellowship.  Dr. Nicholas Nicolaides is a 1987 graduate of Saint Joseph’s University and the CEO of Morphotek.  Nicholas and Susan Nicolaides have been long-time supporters of the SJU Summer Scholars Program.  This fellowship entitles Miranda to receive research supplies and travel funds to present at a scientific conference.  Miranda is working with Dr. Piotr Habdas conducting research on the particle dynamics of dense colloidal suspensions with varying inter-particle potential using confocal microscopy.

Students Present at the 19th Mid-Atlantic Soft Matter Workshop

February 24, 2018

Miranda Mazzio ’18, Rui Zhang ’18, and Michael Jenkins ’19 (left to right) visited University of Maryland in February where they attended the 19th Mid-Atlantic Soft Matter Workshop.  All of them gave oral presentations on their research. Miranda talked about her 3D studies of particle dynamics in dense colloidal suspensions with varying interparticle attraction.  Rui presented preliminary results of studies on motion of a probe particle through dilute colloidal suspensions.  Finally, Mike presented his most recent attempts in applying machine learning to “live” tracking of colloidal particles.

Izzy and Zack presented at the 252nd American Chemical Society National Meeting and Exposition

March 29, 2017

Two of our students attended and presented at the ACS National Meeting in Philadelphia.  Isabella Goodenough ’16 (chemistry major and physics minor) presented a poster titled “Charge Accommodation in n-Doped Ethynyl-Bridged π-Conjugated Porphyrin Arrays”.  Zachery Brown ’17 gave a talk titled “Studying particle dynamics in the reentrant glass transition using colloidal suspensions”.  Awesome job!

Department of Physics hosted AAPT Southeastern Pennsylvania Section Spring 2016 Meeting

March 29, 2017

On April 1st and 2nd the Department of Physics hosted The American Association of Physics Teachers Southeastern Pennsylvania Section Spring 2016 Meeting. Paul Hewitt was the featured guest speaker and gave a presentation titled “Equations as Guides to Thinking” on Friday evening. Saturday’s featured speakers were Paul Steinhardt (Princeton University) who gave a presentation titled “Once Upon a Time in Kamchatka” and Rick VanBerg (University of Pennsylvania) who delivered a talk titled “Sixty Years of Experimental Neutrino Physics – A Somewhat Personal Perspective”. For detailed program please see the flyer.

Zack presented at American Physical Society March Meeting

March 29, 2017

Zachery Brown ’17 attended the APS March Meeting in Baltimore during the March 13th week. He gave a talk titled “Probing Dynamical Heterogeneity in Dense Colloidal Suspensions with Depletion Attraction”. His talk was about his recent results of studies of particle dynamics in dense collodoidal suspensions and was given in a regular science session titled Colloids: Interactions, Structure, Statistics.

Mars, Venus, Jupiter and the Moon in the Morning Sky

March 29, 2017

More than 25 students got up very early to view the three planets and the Moon visible in the morning sky on Wednesday (11/4/15).  They were able to see beautiful images of the three planets and were even able to take a few snapshots with their phones.  Spectacular Jupiter with its Galilean moons wowed the students and the Moon with its craters is always impressive to see.  We will announce the next sky viewing event in advance.
