Penn physics PhD student, Zoey Davidson, in collaboration with Yodh, Collings, and Kamien, explored the physics of a new kind of drying drop - one filled with liquid crystals. The formation of different phases during drying led to dramatically different fluid movement and solid deposition.

Drndic and Johnson’s labs, together with researchers from Penn State, explore the creation and size control of two dimensional tungsten disulfide nanopores with light.
“We’d like to see if we can use this phenomenon, this chemical reaction, to actually make pores with light. As scientists at a university, we have the luxury of playing around a little bit to see what works better,” Drndić says. “We’re able to explore, which can lead to some new ideas. We’re laying down the fundamental basis behind how nanopores work so that one day engineers can continue the technology.”
Congratulations to Sarah Friedensen (far left) who received the 2017 NSF Graduate Fellowship. Sarah’s work includes electronics transport in topological and two-dimensional materials in Prof. Drndic lab.At the 2017 APS March Meeting in New Orleans she gave a talk on "Electron-beam nanosculpting and materials analysis of exfoliated bismuth selenide”
Professor Bhuvnesh Jain and Postdoctoral Fellow Eric Baxter surveyed the sky to find evidence that the dark matter halos surrounding galaxy clusters have a discernible edge. Analysis of a galaxy survey called the Sloan Digital Sky Survey has confirmed the reality of these edges through shifts in the distribution and colors of galaxies. Through their research, they are gaining a better understanding of the nature of dark matter.

The College of Arts and Sciences recognizes the exemplary performance of teaching excellence and committment toward the education of our students. A warm congratulations to Professors Evelyn Thomson and Cullen Blake on being honored as recipients of 2017 awards for distinguished teaching!
Penn Physics alum Jessamyn Fairfield has written a feature for the March 2017 issue of Physics World about neuromorphic electronics, novel devices whose function mimics synaptic function. Neuromorphic features can be realized in a variety of materials, from nanomaterials to polymers, and may enable the development of electronic skin, novel computational paradigms, or smart neuroprosthetics. Jessamyn is currently a professor at NUI Galway in Ireland, and did her PhD research in the Drndic lab on semiconducting nanocrystal optoelectronics.
Physics and Astronomy graduate student, Dillon Fox, is challenged to answer the question "What is energy?" judged by a team of eleven year old scientists in training in a bid to amplify effective communication with the public. To watch Fox's Flame Challenge video entry, visit OMNIA
As published in Advanced Science News, kirigami structures will someday literally reshape our world. These metamaterials have the unique ability to control their shape and design in response to external stimuli. With the introduction of notches, kirigami structures gain even more mobility and control. These enhanced kiri-kirigami implement thermal control and light control that can be especially useful in architecture and energy saving buildings.
