Planetary atmosphere in a tank

Planetary atmosphere in a tank

Chemical engineering • Geosciences • Physics

By César Tomé

Earth’s atmosphere is a vast, swirling engine of weather and climate. Jet streams race across continents, storms spin into hurricanes, and invisible eddies churn the air at every scale. For decades, scientists have struggled to understand exactly how energy and swirling motion flow through these turbulent systems, especially in the layered zones where the air […]

How a shifting photonic crystal creates a robust laser

How a shifting photonic crystal creates a robust laser

Condensed matter • DIPC Advanced materials • Materials

By DIPC

New research numerically demonstrates how carefully structured materials can control light in ways that are both precise and robust. It brings together ideas from photonics and topology to show how a laser can emerge from the boundary between two distinct optical regimes. The physical system considered in the study is a bilayer photonic crystal. A […]

100-meter underground wireless communication

100-meter underground wireless communication

Technology

By Mapping Ignorance

Korean researchers have confirmed that underground wireless communication is possible, moving beyond the terrestrial wireless communication they have primarily focused on until now. This opened up a new wireless channel for confirming the survival of buried people in the event of a collapse of an underground facility such as a mine, conducting underground rescue operations […]

Chiral altermagnets and the unexpected origins of spin currents

Chiral altermagnets and the unexpected origins of spin currents

Condensed matter • DIPC Advanced materials • Materials • Quantum physics

By DIPC

Every time a computer processes information, electrons shuttle through circuits carrying electric charge, and much of the energy they carry is wasted as heat. Spintronics proposes a different approach: instead of relying solely on the charge of electrons, exploit another of their properties called spin, a quantum-mechanical quantity that can be thought of as a […]

How strain shapes the quantum properties of twisted graphene

How strain shapes the quantum properties of twisted graphene

Condensed matter • DIPC Electronic Properties • Materials • Quantum physics

Imagine taking two identical sheets of chicken wire and laying them on top of one another. If you align them perfectly, they look like a single sheet. But if you rotate the top layer by just a tiny amount, a beautiful large-scale crawling pattern emerges. In physics, we call this a Moiré pattern. When we […]

Real-time imaging of the forces that build chemical gardens

Real-time imaging of the forces that build chemical gardens

Chemistry • DIPC Biochemistry • Evolution • Geosciences • Materials

By DIPC

The classic chemical garden experiment is a staple of introductory chemistry, where colorful, plant-like structures sprout from metal salt crystals dropped into a solution of sodium silicate. While these vibrant tubes look like biological life, they are entirely inorganic, driven by the physics of osmosis and the chemistry of precipitation. For decades, scientists have admired […]

12 reasons why plastic recycling is failing so badly

12 reasons why plastic recycling is failing so badly

Chemistry • Economics • Environment • Materials

By Invited Researcher

Author: Jordi Diaz Marcos, CCiTUB , Universitat de Barcelona As good citizens, we diligently fill the recycling bins provided by our local authorities with all manner of plastic trays, boxes, bottles and bags. But as these bins fill up quicker and quicker each week, an awkward question arises: is all this effort actually doing any […]

Crafting the ideal glass in two dimensions

Crafting the ideal glass in two dimensions

Chemistry • Condensed matter • Materials • Physics

By César Tomé

Imagine cooling a liquid so fast it turns into glass: a solid that’s jumbled inside, unlike neat crystal lattices. In 1948, Walter Kauzmann noticed a puzzle. As liquids cool, their entropy (a measure of disorder) drops faster than in crystals. Below a certain temperature, a supercooled liquid would have less entropy than the crystal, implying […]

First living cochlea outside the body unlocks secrets of hearing

First living cochlea outside the body unlocks secrets of hearing

Biomedicine • Medicine • Neuroscience

By Rosa García-Verdugo

Have you ever wondered how your ears can pick up the faintest whisper yet also handle loud music without damage? Scientists at Rockefeller University have achieved a remarkable feat : they kept a tiny piece of cochlea alive and working outside the body, allowing them to witness the hearing process in unprecedented detail. Building a […]

The intertwined nature of electronic waves in 2D TiSe<sub>2</sub>​ crystals

The intertwined nature of electronic waves in 2D TiSe2​ crystals

Condensed matter • DIPC Advanced materials • Materials

By DIPC

When we peel a crystal down to its very last layer, the physics governing its behavior undergoes a radical shift. This transition from the bulk (three-dimensional) to the two-dimensional limit is where some of the most exotic phenomena in condensed matter physics emerge. Among these, Titanium Diselenide, or TiSe₂, has long fascinated researchers because of […]
