One area is so-called spintronics, with devices that encode information in magnetic domains. These magnetic bits can be written, read and erased in a more energy-efficient way than bits in current semiconductor devices. Spin textures and magnetic domains in such materials can be investigated using nanoscale magnetic imaging techniques. For example, photoemission electron microscopy (PEEM), coupled with a magnetically sensitive detection mechanism. https://phys.org/news/2026-07-tiny-magnetic-image-spintronic-materials.html Nanophysics Sun, 12 Jul 2026 17:00:03 EDT news702563676 Light Emitting Diodes (LEDs) are used in everything from household lighting and mobile phones to large display screens.

Their metric promises to take nanomaterials engineering from a process of discovery to one of design, enabling engineers to produce combinations of properties not seen in natural or existing man-made materials. https://phys.org/news/2026-05-complexity-isnt-subjective-amount-results.html Nanomaterials Thu, 21 May 2026 18:20:01 EDT news698594941 All cells, whether big or small, short or long, rely on proteins to function properly. In most cells, transporting these proteins is relatively simple. Neurons in the brain, however, face a significant logistical challenge because their axons, the thread-like structures that carry electrical impulses, can extend for meters. As a result, essential materials produced in the cell body must travel enormous distances to reach the ends of axon terminals. https://phys.org/news/2026-05-neuron-imaging-captures-unconventional-receptor.html Cell & Microbiology Fri, 15 May 2026 15:20:03 EDT news698059304 The task of gently transporting a microscopic particle from one point to another along a winding path, and then bringing it back using nothing more than a single, compact chip is a challenge we set out to address in our new study, now published in Nature Communications. https://phys.org/news/2026-05-optical-metaconveyors-enable-programmable-nanomanipulation.html Nanophysics Wed, 13 May 2026 18:00:02 EDT news697800686 Antiferromagnetic materials, with antiparallel atomic spins and zero net magnetization, are fast and resistant to external magnetic interference, making them ideal for high-speed, high-density spintronic devices.

The answer lies in structures far too small to see—and difficult to access even with advanced techniques. So far, researchers have relied mainly on X-ray methods to understand how molecules are arranged within these materials and how this order can be optimized for high efficiency. While powerful, X-rays provide only a spatially averaged picture. Electrons, in contrast, offer a local view at the nanoscale, revealing both structure and chemical composition. https://phys.org/news/2026-04-electrons-solar-cells-exposing-hidden.html Nanophysics Wed, 15 Apr 2026 18:50:01 EDT news695490421 A new analysis reveals what happens when very short or narrow electron beams encounter a particle.

University at Buffalo researchers have demonstrated this phenomenon by creating the first-ever star-shaped vanadyl hydroxide (VOOH) and shown that this shape can fundamentally alter how the material stores energy. https://phys.org/news/2026-04-pretty-picture-star-nanomaterial-energy.html Nanophysics Tue, 07 Apr 2026 12:40:04 EDT news694776061 The electrons that power our society flow left and right through the circuitry in our electronics, back and forth along the transmission lines that make up our power grid, and up and down to light up every floor of every building. But the electrons in newly discovered "moiré crystals" move in much stranger ways. They can move left and right, back and forth, or up and down in our three-dimensional world, but these electrons also act as if they can teleport in and out of a mysterious fourth dimension of space that is perpendicular to our perceivable reality. https://phys.org/news/2026-04-electrons-moir-crystals-explore-higher.html Condensed Matter Mon, 06 Apr 2026 10:00:03 EDT news694685941 A team led by scientists at the National Graphene Institute (NGI) at The University of Manchester has developed the first technique capable of capturing atomic‑resolution videos of individual gold atoms 'dancing' across a surface surrounded by liquid, opening a window into a hidden atomic world that has been invisible until now. https://phys.org/news/2026-04-graphene-nano-aquariums-capture-atomic.html Nanomaterials Thu, 02 Apr 2026 14:00:03 EDT news694340281 Scientists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a new way to determine atomic structures from nanocrystals previously considered unusable, a breakthrough that could transform how researchers study materials too small or imperfect for conventional crystallography. https://phys.org/news/2026-03-4d-stem-method-isolates-atomic.html Nanomaterials Wed, 04 Mar 2026 04:17:13 EST news691820185 A stretchy, conductive type of plastic could help power the next generation of implantable biomedical devices, like longer-lasting pacemakers or glucose monitors, according to Enrique Gomez, professor of chemical engineering at Penn State. https://phys.org/news/2026-02-stretchy-plastics-electricity-tiny-whisker.html Bio & Medicine Mon, 23 Feb 2026 10:20:04 EST news691062601 Researchers from the Institute of Metal Research (IMR) of the Chinese Academy of Sciences have developed a new ferroelectric ultraviolet photodetector material that overcomes the long-standing performance limitations of conventional photodetectors. https://phys.org/news/2026-01-ferroelectric-ultraviolet-photodetector.html Condensed Matter Wed, 28 Jan 2026 15:00:32 EST news688834801 Researchers from the Institute of Metal Research (IMR) of the Chinese Academy of Sciences have stretched a chain of gold atoms by a record-breaking 46%, providing direct evidence of how fundamental metal bonds behave under extreme deformation.
