Fast and slow surfactants in turbulence-driven bubble breakup

Fast and slow surfactants in turbulence-driven bubble breakup

Zhan Rui Wu, Tristan Aurégan, Luc Deike

A stormy patch of water can make bubbles in two very different ways: surfactants may leave the larger bubbles untouched while creating up to five times as many tiny ones. The key is not just what the surfactant is, but how fast it arrives.

Solvent effects on the electronic structure, excited states, and nonlinear optical properties of two anthracene-based chalcone derivatives: a DFT and TD-DFT study

What if the liquid around a molecule could change not just how it absorbs light, but which of two molecules appears more powerful? This study finds that the answer can switch with the solvent.

Assessing primary health care network preparedness for future pandemics in Lebanon

Assessing primary health care network preparedness for future pandemics in Lebanon

Zeina Salaheddine Mneimneh, Michele Kosremelli-Asmar

A health clinic can report a dangerous disease quickly and still be unprepared for the next pandemic. In Lebanon, that contradiction is exactly what this study uncovered.

Tsunamigenic potential of flank instabilities of Kameni Volcano inside Santorini Caldera, southern Aegean

Tsunamigenic potential of flank instabilities of Kameni Volcano inside Santorini Caldera, southern Aegean

Benedikt Bauer, J. Preine, P. Nomikou, Tom Kwasnitschka, María Blanch Jover, Jens Karstens, Félix Gross, Lars Helmuth Rüpke, Heidrun Kopp

Santorini’s volcano could pose a tsunami threat not only through an eruption, but through a sudden collapse of its own side. The most severe modeled wave could reach thirty-nine meters.

Probing flavour deconstruction via primordial gravitational waves

Probing flavour deconstruction via primordial gravitational waves

Noemi Fabri, Gino Isidori, Davide Racco

A faint ripple from the early Universe could reveal particles that no collider can reach. But this study finds the signal may be hiding at a higher pitch than the detector many people are counting on.

Residual monomers and volatile leachable substances of conventional and CAD/CAM-fabricated denture base materials — GC-MS analysis and surface characterization

Residual monomers and volatile leachable substances of conventional and CAD/CAM-fabricated denture base materials — GC-MS analysis and surface characterization

Viktor Martian, Christoph Sasse, Ralf Bürgers, Andrea Schubert, Oskar Bunz

A denture can contain leftover building blocks from its manufacture. But in this study, the material with the most detectable residue did not release more of one key substance than plain control liquid.

Thermal sculpting of nanoconfined single-atom cavities enables urea electrosynthesis with near-unity selectivity

Thermal sculpting of nanoconfined single-atom cavities enables urea electrosynthesis with near-unity selectivity

Boxuan Yang, Yuxin Zeng, Lifeng Yin, Yunrong Dai, Qingsong Hua

Fertilizer production helps feed nearly half the world, but it consumes huge amounts of energy and creates carbon dioxide. This study turns waste gases and wastewater into fertilizer inside a space far smaller than a human hair is wide.

A frightening memory can protect you, or make a safe place feel dangerous. This study finds that the brain can change how widely fear spreads without changing how strong the fear itself is.

AAC Access and Interventions for Children with Motor and Speech Disabilities

AAC Access and Interventions for Children with Motor and Speech Disabilities

Dawn J. Sowers, Savanna Brittlebank, Krista M. Wilkinson

For a child who cannot reliably speak or point, the hardest part may not be finding words. It may be finding a way to select them, and research shows that the right access method can change communication itself.

High-throughput study of electrical conductivity in ordered metals

High-throughput study of electrical conductivity in ordered metals

Thalis H. B. da Silva, Hai-Chen Wang, Tiago F. T. Cerqueira, Simone Di Cataldo, Silvana Botti, Miguel A.L. Marques

Every phone, power line, and computer depends on electricity moving easily through metal. This study asks whether a computer can search millions of possible compounds and uncover conductors that could rival the best metals we already use.

Protecting a remarkable landscape is only half the challenge. The research on these places has built strong tools for conservation, but the way people discover, understand, and choose to visit them remains much less clearly developed.

Terahertz field-induced giant symmetry modulations in a van der Waals antiferromagnet

Terahertz field-induced giant symmetry modulations in a van der Waals antiferromagnet

Sheikh Rubaiat Ul Haque, Martin J. Cross, Sangeeta Rajpurohit, Jonah B. Haber, Christopher J. Ciccarino, Alexandra C. Zimmerman, Isabelle J. Sealey, V. A. Kulichenko, Monique Tie, Huaiyu Hugo Wang, Sharon S. Philip, Choongwon Seo, J. D. Koralek, Luis Balicas, Mykhaylo Ozerov, Dmitry S. Smirnov, Liang Zheng Tan, Felipe H. da Jornada, Tadashi Ogitsu, Matthias C. Hoffmann, Tony F. Heinz, Aaron M. Lindenberg

A flash of terahertz light makes a magnetic crystal move as though its hidden internal order has suddenly been rearranged. The striking part is that the crystal’s visible symmetry changes and keeps oscillating long after the flash.
