The future of human-machine interfaces is on the cusp of a revolution with the unveiling of a groundbreaking technology—a stretchable high-resolution multicolor synesthesia display that generates synchronized sound and light as input/output sources. A research team, led by Professor Moon Kee Choi in the Department of Materials Science and Engineering at UNIST, has succeeded in developing this cutting-edge display using transfer-printing techniques, propelling the field of multifunctional displays into new realms of possibility.

The team’s research is published in the journal Advanced Functional Materials.

Traditionally, multifunctional displays have been confined to visualizing mechanical and electrical signals in light. However, this pioneering stretchable synesthesia display shatters preconceived boundaries by offering unparalleled optical performance and precise sound pressure levels. Its inherent stretchability ensures seamless operation under both static and dynamic deformation, preserving the integrity of the sound relative to the input waveform.

A detailed experimental analysis explains the forces by which a spinning magnet can cause another magnet to levitate in midair.

Magnetic levitation is common in floating trains and high-speed machinery, but two years ago, a new type of levitation was discovered that uses a rapidly rotating magnet to suspend a second magnet in the air. Researchers have now clarified that this phenomenon originates from slight tilts in the magnetic axes of the magnets relative to their rotational axes [1]. The research team’s experimental and theoretical work reveals surprises about how magnetic levitation works. The new technique could one day be used as a contact-free tool for manipulating objects.

If you bring together two toy magnets with their north poles facing each other, they will repel each other. You might be tempted to try and use that repulsion to counter the force of gravity by placing one magnet beneath the other. However, common experience shows that this balancing act is unstable.

Lab experiments and theoretical models elucidate how chains of light-harvesting bacteria assemble into various density-dependent structures.

A new method identifies the most sensitive measurement that can be performed using a given quantum state, knowledge key for designing improved quantum sensors.

A quantum sensor is a device that can leverage quantum behaviors, such as quantum entanglement, coherence, and superposition, to enhance the measurement capabilities of a classical detector [1–5]. For example, the LIGO gravitational-wave detector employs entangled states of light to improve the distance-measurement capabilities of its interferometer arms, allowing the detection of distance changes 10,000 times smaller than the width of a proton. Typically, quantum sensors use systems prepared in special quantum states known as probe states. Finding the ideal probe state for a given measurement is a focus of many research endeavors. Now Jarrod Reilly of the University of Colorado Boulder and his colleagues have developed a new framework for optimizing this search [6].

Two different experiments on two different transition metals reveal that a current of electron orbital angular momentum flows in response to an electric field.

In the spin Hall effect, an applied electric field drives a current of electron spin in a direction transverse to the field. In a transition metal, theorists predict that an orbital angular momentum (OAM) current can also flow. Now two groups have independently observed this so-called orbital Hall effect (OHE) [1, 2]. These observations supplement one made by a third group earlier this year [3]. Together these demonstrations constitute a step toward the development of “orbitronic” devices based on an electron’s orbital degree of freedom.

For their demonstration, Giacomo Sala of the Swiss Federal Institute of Technology (ETH) in Zurich and his colleagues turned to a phenomenon known as Hanle magnetoresistance. In a conductor, when a magnetic field is applied parallel to the direction of electron OAM, orbital moments should accumulate at the edges of the sample because of the OHE. If instead the field is applied perpendicular to electron OAM, the orbital moments should precess. The orbital moments should then fall out of phase with each other, which boosts the material’s magnetoresistance. The team observed these effects in thin films of manganese [1].

New Horizons’ mission of exploration of the outer solar system will continue, according to a recently announced updated plan from NASA.

Beginning in fiscal year 2025, New Horizons will focus on gathering unique heliophysics data, which can be readily obtained during an extended, low-activity mode of operations.

In a surprising new study, researchers at the University of Minnesota Twin Cities have found that the electron beam radiation that they previously thought degraded crystals can actually repair cracks in these nanostructures.

The groundbreaking discovery provides a new pathway to create more perfect crystal nanostructures, a process that is critical to improving the efficiency and cost-effectiveness of materials that are used in virtually all electronic devices we use every day.

“For a long time, researchers studying nanostructures were thinking that when we put the crystals under electron beam radiation to study them that they would degrade,” said Andre Mkhoyan, a University of Minnesota chemical engineering and materials science professor and lead researcher in the study. “What we showed in this study is that when we took a crystal of titanium dioxide and irradiate it with an electron beam, the naturally occurring narrow cracks actually filled in and healed themselves.”
