Huge 3D Printing Breakthrough! Caltech is printing metal atom by atom. A hydrogel scaffold soaked in metal salts becomes the blueprint, the gel burns away, and oxygen is stripped in a hydrogen-rich chamber, leaving alloys crafted with surgical precision. They can change metal ratios on the fly. Flip from a copper-heavy mix to a Cu12Ni88 alloy nearly four times stronger, without altering shape or tooling. Every property, from strength to density, is now designed, not guessed. This is metallurgy reinvented. Also a game changer for Aerospace applications. caltech.edu/about/news/bring…

Just published in @ChemRxiv: A Practicable Measure and Spatial Visualization of Steric repulsion with Atomic Resolution ==> chemrxiv.org/engage/chemrxiv… We successfully present a method to hunt one of the unicorn of #Chemistry: steric repulsion! #compchem @khartab

Excited to share a primer* my team and I wrote for ACS as an entry piece to the field of ion soft landing + single molecule imaging! pubs.acs.org/doi/book/10.102… * A pedagogical piece bridging a complete stranger to review papers in the field!

Renormalisation is a central concept in modern physics. It describes how the dynamics of a system change at different scales. A great way to understand and visualise renormalisation is the Ising model (some math, but one can follow without it ) 1/13

Curious to see what people think about this, we had quite a debate at the Editorial Board. After the reviews came in, the conclusion was that, on the great wide spectrum that stretches from bonkers to brilliant, this is closer to brilliant. science.org/doi/full/10.1126…

HISTORY OF PHYSICS What's wrong with this Lagrangean? by David Mermin. [This is so funny that I'll post it in full]

(5/5) The presence of a global ring current shows that the molecule behaves as a quantum object instead of a classical one. We predict such currents in rings with a circumference of almost 20 nm, which makes the molecular quantum world much bigger than previously thought (~5 nm).

🧵 Using nc-AFM, we've visualized #cyclodextrins (CDs) with submolecular resolution— molecules made of glucose units with the remarkable ability to "trap" other molecules. 1/10 (paper in Nat Comm: rdcu.be/dYWOL)
