Nicole Sharp<p><strong>Ultra-Soft Solids Flow By Turning Inside Out</strong></p><p>Can a solid flow? What would that even look like? <a href="https://doi.org/10.1103/PhysRevLett.134.058205" rel="nofollow noopener noreferrer" target="_blank">Researchers explored</a> these questions with an ultra-soft gel (think 100,000 times softer than a gummy bear) pumped through a ring-shaped annular pipe. Despite its elasticity — that tendency to return to an original shape that distinguishes solids from fluids — the gel does flow. But after a short distance, furrows form and grow along the gel’s leading edge. </p> Front view of an ultra-soft solid flowing through an annular pipe. The furrows forming along the face of the gel are places where the gel is essentially turning itself inside out. <p>Since the gel alongside the pipe’s walls can’t slide due to friction, the gel flows by essentially turning itself inside out. Inner portions of the gel flow forward and then split off toward one of the walls as they reach the leading edge. This eversion builds up lots of internal stress in the gel, and furrowing — much like crumpling a sheet of paper — relieves that stress.

Nicole Sharp<p><strong>Cooking Perfect Cacio e Pepe</strong></p><p>In cooking, sometimes the simplest recipes are the toughest to master. Cacio e pepe — a classic three-ingredient Italian pasta — is an excellent example. Made properly, the sauce of cheese and black pepper combines with starchy water to coat the pasta in a uniform, cheesy sauce. Or, if you’re me, you wind up with a pasta sauce flecked with stringy clumps of melted cheese. Fortunately for those of us who have yet to master this one, a <a href="https://arxiv.org/abs/2501.00536" rel="nofollow noopener noreferrer" target="_blank">new research paper</a> has us covered with tips to make the perfect cacio e pepe. </p><p>The key to that elusive silky sauce, they found, is the starch – water – cheese combination. Your water needs just the right amount of starch — they found that between 1 – 4% starch by (cheese) mass worked. If the starch concentration is too low (which can easily happen in pasta water), you’ll get the clumpy cheese mess that so frequently happens in my kitchen. Temperature is also critical; if the water is too hot when it’s added, then it can destabilize the sauce. Check out the <a href="https://arxiv.org/abs/2501.00536" rel="nofollow noopener noreferrer" target="_blank">pre-print’s Section V</a> for the scientific, supposedly foolproof, recipe.

Nicole Sharp<p>This planet-like balloon started out as two elastomer sheets, heat-sealed together into a spiraling tube. As the balloon was inflated, it changed from flat to a saddle-like shape. With more air, the pressure inside increased, triggering an instability that caused the middle of the balloon to bulge. As inflation continued, the central bulge expanded, unbonding layer after layer of the seal. Even late in inflation, the balloon maintains hints of its original shape in the form of a ring around the Jovian bulge in the middle.

Dom<p><a href="https://qoto.org/tags/SoftMatter" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>SoftMatter</span></a> have just published the <a href="https://doi.org/10.1039/D2SM01188C" rel="nofollow noopener noreferrer" target="_blank">results</a> of a project that Renato Assante, Davide Marenduzzo, Alexander Morozov, and I recently worked on together! What did we do and what’s new? Briefly…</p><p><a href="https://qoto.org/tags/Microswimmer" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Microswimmer</span></a> suspensions behave in a similar way to fluids containing kinesin and microtubules. Both systems can be described by the same system of three coupled nonlinear <a href="https://qoto.org/tags/PDEs" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>PDEs</span></a>.</p><p>A <a href="https://qoto.org/tags/LinearStabilityAnalysis" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>LinearStabilityAnalysis</span></a> of these equations suggests that variations in concentration across the system don’t significantly affect emergent <a href="https://qoto.org/tags/phaseBehaviour" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>phaseBehaviour</span></a>. How then can we explain <a href="https://qoto.org/tags/experiments" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>experiments</span></a> that show visible inhomogeneities in <a href="https://qoto.org/tags/microtubule" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>microtubule</span></a>–<a href="https://qoto.org/tags/kinesin" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>kinesin</span></a> mixtures, for instance?</p><p>With increasing activity, we move away from the quiescent regime, past the onset of <a href="https://qoto.org/tags/SpontaneousFlow" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>SpontaneousFlow</span></a>, and deeper into the active phase, where <a href="https://qoto.org/tags/nonlinearities" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>nonlinearities</span></a> become more important. What role do concentration inhomogeneities play here?</p><p>We investigated these questions, taking advantage of the <a href="https://qoto.org/tags/openSource" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>openSource</span></a> <a href="https://qoto.org/tags/Dedalus" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Dedalus</span></a> <a href="https://qoto.org/tags/spectral" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>spectral</span></a> framework to simulate the full nonlinear time evolution.

As a result, domains reach a characteristic size that decreases with increasing activity.</p><p>This regime is one part of the <a href="https://qoto.org/tags/PhaseDiagram" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>PhaseDiagram</span></a> we mapped out.
