It all started a couple of years ago in a discussion with Mario Mencia about proton transfer in bacterial membranes vs. archaeal ones. I told him we can give it a go, and we found some interesting, unexpected capability of ether lipids to support proton diffusion.

The role of ester- versus ether-linked phospholipids in the ability of biological membranes to accept protons and support proton diffusion In biology, the distribution of ester-linked versus ether-linked phospholipids is meaningful, such as in the abundance of ether-linked phospholipids i…

📢New paper 🥳Check out our new publication in @biophysj.bsky.social @biophysicalsoc.bsky.social as part of our series exploring proton transfer diffusion on the surface of biological membranes. sciencedirect.com/science/arti...
This time, we focus on the role of ester-linkage vs. ether-linkage ->

Starting our 3 weeks experiment at the Central Laser Facility. Fingers crossed 🤞

A Molecular Donor-Acceptor System to Induce and Visualize Proton Transfer Across Biomolecules Proton transfer (PT) is at the heart of fundamental natural biochemical reactions, e.g. in bioenergetics, where proteins are the main proton mediators. PT between two specific points requires a change...

I have never been so excited about a Preprint @chemrxiv.bsky.social. An idea started 10 years ago, and experiments started nearly 8 years ago, we finally present the first-ever Donor-Bridge-Acceptor system to initiate and explore proton transfer across biomolecules.

The role of lipid phase and temperature in proton barrier and proton migration on biological membranes Biological membranes play a major role in diffusing protons on their surfaces between transmembrane protein complexes. The retention of protons on the membrane's surface is commonly described by a mem...

With that note, Happy New Year to everyone. May the new year bring winds of good change and peace (or at least quiet) to our world.

I want to thank the Technion in Israel, which will always be my second home and where I have made so many good friends. Making that decision was one of my hardest, and I am sad that the state of my home country has pushed me away from the workplace I love so much. ->

I want to thank the University of Sheffield for believing in my science and offering me a full professor position in Chemistry. I am looking forward to making great science with the great people I have already met there. ->

🧵As the year ends, I wish all my friends and colleagues the best in 2025.
For me, 2024 was quite a ride. While some of you may know, I never wrote anything publicly about it. Earlier this year, my wife and I decided to move out of Israel and start a new adventure. ->

It is one of these black science magic that you don't understand in the beginning how this counter-intuitive thing can work, but suddenly it does. Congrats to Amit and Ziyu for this achievement.

Aqueous‐Based Assembly of Plant‐Derived Proteins Yields a Crosslinker‐Free Biodegradable Bioplastic Consistent with Green Chemistry Principles An aqueous-based sustainable formulation strategy is presented to create bioplastic from abundant and sustainable plant-derived proteins. The new formulation does not use any cross-linkers or convent...

Finally it is out!🥳 Our new generation of bioplastics made from plant-derived proteins. We developed an aqueous-based methodology that uses no cross-linkers or traditional platicizers. Published in ChemSusChem #Sustainabilty #Bioplastics
