The Scherer group introduced a method of calculating the entropy production rate of overdamped, non-conservative, N-body systems. Their article in Physical Review E uses a novel collective mode decomposition and force field decomposition to show that the rates of entropy production and power dissipation are equal in these systems, in agreement with a theorem by Seifert.

The King group introduced a strategy for functionalizing a sulfur-containing transition metal dichalcogenide (TMD) with multimolecular architectures.
Their article in ACS Applied Optical Materials describes how molecular adsorption in the growth and characterization of ion-linked bilayers offers a new pathway to introduce complex molecules onto sulfur-containing TMDs.

Princeton University Press published Soft Matter: Concepts, Phenomena, and Applications by Vincenzo Vitelli, Wim Van Saarlos, and Zorana Zeravcic.

NanoPattern Technologies cofounded by Dmitri Talapin has raised $1.5 million, including a $1 million NSF grant, to expand its work creating commercial quantum dot ink.

The Irvine group created a novel active matter system that can self propel, flock, and form a chiral active phase. Their publication in Nature Physics explains how a suspension of magnetic particles driven to spin at intermediate Reynolds numbers with a rotating magnetic field was able to behave as a synthetic active system.

The annual Physics With A Bang MRSEC open house welcomed 400 visitors of all ages on Dec. 9 to get them excited about science. Attendees explored a hall of interactive demonstrations, toured lab spaces, and watched Heinrich Jaeger and Sidney Nagel’s double act of dazzling science presentations.

The Vitelli and Gardel groups created new models for predicting cell traction forces. Their paper in Cell details how trained neural networks could predict the forces created by complex biochemistry using images of just fluorescent zyxin proteins.
