We are cxcited to represent UCLA Chemical & Biomolecular Engineering at the #APS2025 Global Physical Summit @APSPhysics! 🚀 Our group will present 9 talks + 4 posters showcasing our latest research. Check out our lineup, and we hope to connect with you there!
Our latest publication in @ChemCommun , led by @FahedAlbreiki , introduces a modular synthesis of catechol-containing triblock copolymers that form strong and wet adhesives!

@UclaCBE @UCLAengineering @UCLA #NSFfunded #MusselAdhesion #Hydrogels
In this work, we utilize ring opening polymerization and thiol-ene click chemistry to produce triblock polycatechol (tbPC) - polymers that feature high density of catechol endblocks bridged with a hydrophilic PEG middle block.
The result? Cross-linkable polymers that gel rapidly and achieve robust adhesion across diverse surfaces - marking a stark enhancement in properties compared to conventional catechol-based wet adhesives.

Excited and proud of Advait Holkar, a graduate of our lab, who has been selected as an Activate Fellow! He is launching Prāio Inc., which will focus on enabling low-cost production of sustainable aviation fuel (SAF) through a pioneering protocellular biocatalysis platform (1/2)
Advait developed this innovative technology in his graduate research. Join us in supporting this solution to reduce CO2 emissions and drive sustainable aviation! 🌍✈️

🚀 The latest study from @samanvaya's group shows that comb polyelectrolyte stabilizers improve coacervate microdroplet stability for drug delivery. Thanks to @BioPACIFICMIP, high-throughput materials characterization was possible.

Number density and avg. microdroplet size are shown to be controlled by varying the cPE and salt concentrations. Turbidity maps, akin to binodal phase maps, depict an expansion of the turbid two-phase region. (5/6)
Our group members spent a fun afternoon at the Willows Community School’s Sunday Funday with 100+ kids excited to learn about polymers, surface tension and complex fluids!

We developed inks comprising gelatin and block polyelectrolyte scaffolds that were printable at physiological temperatures in commercial extrusion-based printers w/ high resolution (<0.5 mm).
We provide insights about their viscoelastic properties and 3D printability assessments.
Thanks to our collaborators at @KITKarlsruhe and @BioPACIFICMIP for their valuable contributions!
