Rheology: In-Depth Description

Rheology is the branch of physics and materials science that studies the deformation and flow of matter, primarily in liquids, soft solids, and complex fluids that do not follow the simple laws of viscosity or elasticity. Its primary goal is to understand and predict how materials respond to applied forces, stresses, or strains over time.

Image Credit: Scientific Frontline

Scientific Frontline: Extended "At a Glance" Summary

The Core Concept: Researchers have identified specific achiral "parent" materials that can be engineered into electronically chiral materials with a single, uniform handedness through targeted structural distortion.

Key Distinction/Mechanism: Unlike traditional materials where resistivity increases as they shrink (e.g., copper), these parent compounds utilize specific electronic structures—visualized as "figure eight" shapes on their Fermi surfaces—that can be manipulated. By adjusting electron filling and applying distortion, these achiral precursors transition into chiral conductors that may maintain or even decrease electrical resistance at microscopic scales.

Origin/History: The discovery was announced in January 2026 by physicists at Martin Luther University Halle-Wittenberg (MLU) and the Max Planck Institute for Microstructure Physics. The findings were published in Nature Communications (2025) and are central to the new "Centre for Chiral Electronics" (EXC 3112).

Major Frameworks/Components:

• Chirality: The geometric property where an object (or electronic structure) cannot be superimposed onto its mirror image.
• Fermi Surfaces: The abstract boundary in momentum space useful for predicting the electrical properties of metals; here specifically observed as "figure eight" (Octdong) or Spindle-Torus shapes.
• Kramers Nodal Line Metals: The specific class of metallic materials investigated for these tunable electronic properties.

Branch of Science: Condensed Matter Physics, Microelectronics, and Materials Science.

Future Application: Development of next-generation microchips that are significantly faster, more robust, and energy-efficient by utilizing thin layers of materials with uniform electronic chirality.

Why It Matters: As conventional microelectronics approach physical limits where shrinking components causes unmanageable electrical resistance, this discovery offers a viable pathway to bypass those limits, enabling the continued miniaturization and efficiency of computing technology.

Rare earth elements (REEs) are crucial for energy-related applications and are expected to play an increasingly important role in emerging technologies. However, these elements have very similar chemical properties and naturally coexist as complex mixtures in both traditional and unconventional feedstocks, making their separation challenging. Researchers in the Non-Equilibrium Transport Driven Separations (NETS) initiative used standard low-cost permanent magnets to induce a magnetic field gradient in solutions containing REEs. They found that these permanent magnets create local magnetic fields strong enough to lead to regions enriched in REE ions, with concentration increases of up to three to four times the concentration of the starting solution. Directly observing magnetic field–driven ion enrichment in real time, without intrusive probes that disturb the system, has long been a challenge. The development of a new high-throughput Mach–Zehnder interferometry imaging capability has now enabled visualization of these dynamics as they unfold.

Scientists have found a way to make perovskite solar cells not only highly efficient but also remarkably stable, addressing one of the main challenges holding the technology back from widespread use. 

Perovskite has long been hailed as a game-changer for the next generation of solar power. However, advances in material design are still needed to boost the efficiency and durability of solar panels that convert sunlight into electricity. 

Led by Professor Thomas Anthopoulos from The University of Manchester, the research team achieved this by fine-tuning the molecules that coat the perovskite surfaces. They utilized specially designed small molecules, known as amidinium ligands, which act like a molecular “glue” to hold the perovskite structure together.

Researchers at the Paul Scherrer Institute PSI have achieved a breakthrough on the path to practical application of lithium metal all-solid-state batteries – the next generation of batteries that can store more energy, are safer to operate, and charge faster than conventional lithium-ion batteries. 

All-solid-state batteries are considered a promising solution for electromobility, mobile electronics, and stationary energy storage – in part because they do not require flammable liquid electrolytes and therefore are inherently safer than conventional lithium-ion batteries. 

Two key problems, however, stand in the way of market readiness: On the one hand, the formation of lithium dendrites at the anode remains a critical point. These are tiny, needle-like metal structures that can penetrate the solid electrolyte conducting lithium ions between the electrodes, propagate toward the cathode, and ultimately cause internal short circuits. On the other hand, an electrochemical instability – at the interface between the lithium metal anode and the solid electrolyte – can impair the battery’s long-term performance and reliability.

FAMU-FSU College of Engineering researchers are applying fuel cell technology to new applications like sustainable energy and water treatment.

In a study published in Frontiers in Membrane Science and Technology, the researchers examined a type of membrane called a perfluorosulfonic acid polymer membrane, or PFSA polymer membrane. These membranes act as filters, allowing protons to move through, but blocking electrons and gases.

In the study, the researchers examined how boiling these membranes — a common treatment applied to the material — affects their performance and helps them work as specialized tools for different applications.

The knots in your shoelaces are familiar, but can you imagine knots made from light, water, or from the structured fluids that make LCD screens shine? 

They exist, and in a new Nature Physics study, researchers created particle-like so-called “vortex knots” inside chiral nematic liquid crystals, a twisted fluid like those used in LCD screens. For the first time, these knots are stable and could be reversibly switched between different knotted forms, using electric pulses to fuse and split them. 

“These particle-like topological objects in liquid crystals share the same kind of topology found in theoretical models of glueballs, experimentally-elusive theoretical subatomic particles in high-energy physics, in hopfions and heliknotons studied in light, magnetic materials, and in vortex knots found across many other systems,” explains Ivan Smalyukh, director of the Hiroshima University WPI-SKCM² Satellite at the University of Colorado Boulder and a professor in CU Boulder’s Department of Physics. 

Rice researchers uncover the hidden physics of knot formation in fluids

Knots are everywhere — from tangled headphones to DNA strands packed inside viruses — but how an isolated filament can knot itself without collisions or external agitation has remained a longstanding puzzle in soft-matter physics.

Now, a team of researchers at Rice University, Georgetown University and the University of Trento in Italy has uncovered a surprising physical mechanism that explains how a single filament, even one too short or too stiff to easily wrap around itself, can form a knot while sinking through a fluid under strong gravitational forces. The discovery, published in Physical Review Letters, provides new insight into the physics of polymer dynamics, with implications ranging from understanding how DNA behaves under confinement to designing next-generation soft materials and nanostructures.

“It is inherently difficult for a single, isolated filament to knot on its own,” said Sibani Lisa Biswal, corresponding author, chair of Rice’s Department of Chemical and Biomolecular Engineering and the William M. McCardell Professor in Chemical Engineering. “What’s remarkable about this study is that it shows a surprisingly simple and elegant mechanism that allows a filament to form a knot purely because of stochastic forces as it sediments through a fluid under strong gravitational forces.”

Electrodes created using light

Visible light can be used to create electrodes from conductive plastics completely without hazardous chemicals. This is shown in a new study carried out by researchers at Linköping and Lund universities. The electrodes can be created on different types of surfaces, which opens up for a new type of electronics and medical sensors. 

“I think this is something of a breakthrough. It’s another way of creating electronics that is simpler and doesn’t require any expensive equipment,” says Xenofon Strakosas, assistant professor at the Laboratory of Organic Electronics, LOE, at Linköping University. 

Breakthrough could connect quantum computers at 200 times longer distance

New research from University of Chicago Pritzker School of Molecular Engineering Asst. Prof. Tian Zhong could make it possible for quantum computers to connect at distances up to 1,243 miles, shattering previous records.

A new nanofabrication approach could increase the range of quantum networks from a few kilometers to a potential 2,000 km, bringing quantum internet closer than ever

Quantum computers are powerful, lightning-fast and notoriously difficult to connect to one another over long distances. 

Previously, the maximum distance two quantum computers could connect through a fiber cable was a few kilometers. This means that, even if such cable were run between them, quantum computers in downtown Chicago’s Willis Tower and the University of Chicago Pritzker School of Molecular Engineering (UChicago PME) on the South Side would be too far apart to communicate with each other.
