Excited to share our latest paper in @softmatter! 🎉
We show how the pressure equation of state of an active suspension can be extracted from its sedimentation profile.
Great work by Yunhee, Elijah, and Parvin!

One does not simply compute the equation of state of a suspension of active colloids.
But with sedimentation equilibrium… one might.
🧪 Recent preprint from our group — excellent work by Parvin, Yunhee, and Elijah!

Excited to share our latest work out in @J_A_C_S ! Building off previous observations that oxidative additions to electrophilic metals might be a little different... including evidence for the first Pd(IV)-dihydride.

New publication from our group @softbiocol led by Vivien Willems.
Check the group Twitter thread about it below👇
Very excited to get this work published! A step forward on active soft microsystems
Thanks to all the colleagues who made this happen!

Publication Alert!🎉
🚀🧪 New paper out! @softmatter
We show that Janus lipid vesicles can self-propel under AC electric fields, exhibiting run-and-tumble dynamics—just like bacteria, but driven by membrane-phase behavior.

🚀🚀 Tiny robots, big questions! Our work on active colloids is featured in @penn_state’s latest Q&A.
Grateful for the spotlight on our efforts to uncover how microswimmers self-organize, move, and transport.

🚶♂️ Hate waiting in line? So do active particles! Our new @JChemPhys paper shows how self-propulsion reshapes single-file diffusion.
Great work by Akin Akintunde, Parvin Bayati, and @HyeongjooRow.

Thrilled to see this paper published @ScienceAdvances!
In it, we describe how growing bacterial colonies form metastable “living gels” in polymeric fluids.
Check it out at doi.org/10.1126/sciadv.adq77…!

Excited to release our latest work, led by Sebastian Gonzalez La Corte (@sesgonzalez) with Ned Wingreen: doi.org/10.1101/2024.04.18.5…!
Here, we show that polymers unexpectedly sculpt proliferating bacterial colonies into spaghetti-like "cables".🦠🍝

The paper that launched the field of self-propelled autonomous nanomotors — extremely small particles that can move on their own — was written by our own Ayusman Sen, Verne M. Willaman Professor of Chemistry, and is celebrating its 20th anniversary.

We had the absolute pleasure of hosting Nobel laureate Stan Whittingham @binghamtonu this week for the Allcock Alumni Lectureship!!
Our faculty and students engaged in discussions about his work on lithium-ion batteries, and shared updates on our department's activities. ⬇️

Now in @J_A_C_S . When a microdroplet is out-of-equilibrium (e.g. solubilizing), partitioning of molecules (like surfactant) can take unexpected pathways.
