MXene-polymer composite enables printed, eco-friendly device for energy harvesting and motion-sensing

Researchers at Boise State University have developed a novel, environmentally friendly triboelectric nanogenerator (TENG) that is fully printed and capable of harvesting biomechanical and environmental energy while also functioning as a real-time motion sensor. The innovation leverages a composite of Poly (vinyl butyral-co-vinyl alcohol-co-vinyl acetate) (PVBVA) and MXene (Ti3C2Tx) nanosheets, offering a sustainable alternative to conventional TENGs that often rely on fluorinated polymers and complex fabrication.

TENGs are innovative energy-harvesting devices that convert mechanical energy into electricity using the triboelectric effect. They were invented by Prof. Zhong Lin Wang of the Georgia Institute of Technology and generate power through contact and motion between materials, making them ideal for applications like wearable electronics, IoT sensors, and self-powered devices.

This work, published in the journal Nano Energy and led by Ph.D. student Ajay Pratap under the supervision of Prof. David Estrada of the Micron School of Materials Science and Engineering at Boise State University, showcases how additive manufacturing can produce high-performance, skin-compatible, and flexible devices for real-world applications in energy harvesting, wearables electronics, and human-machine interaction.

Molecular machinery in cardiac mitochondria reacts to metabolic stress in unexpected way

In a recent study published in Nature Communications, researchers at Karolinska Institutet report that the molecular machinery responsible for cellular energy conversion is more interconnected than previously understood, shedding light on how mitochondria adapt under stress.

Mitochondria generate most of the cell’s energy by converting nutrients into ATP, the molecule that powers nearly all cellular processes. Although ATP synthase and metabolic pathways such as the tricarboxylic acid (TCA) cycle have long been known to work together, they have generally been viewed as separate systems.

Nanopattern method unlocks precise control of disorder for wave-guiding devices

A research team has developed a methodology to precisely design and control the “degree of disorder” in nanopattern arrays using metal-infiltrated block copolymer (BCP) thin films. The work was led by Professor So Youn Kim of the Seoul National University College of Engineering Department of Chemical and Biological Engineering, in collaboration with Professor Su-Mi Hur’s team at DGIST and Professor S. Joon Kwon’s team at Sungkyunkwan University. The paper is published in the journal Nature Communications. The study was selected as an Editors’ Highlight in materials science and chemistry.

This disordered nanopattern fabrication technology is regarded as an innovative approach that enables precise control of nanoscale disorder structures—previously difficult to regulate—thereby opening new possibilities in the design of nano-optical and nanoelectronic devices.

In ordered structures, waves propagate over long distances, whereas in disordered structures, repeated scattering can lead to localization, where waves remain confined within a specific region. Such disordered structures exhibit unique functionalities that can induce localization phenomena for various types of waves, including light, sound and heat.

What really controls water chemistry in nanoscale spaces

Water is the most studied molecule on Earth, yet a surprisingly basic question has gone unanswered for decades: When water is squeezed into gaps just a few molecules wide—as happens inside nanoscale pores, membranes and biological channels—does it become more or less chemically reactive?

This matters because water’s most fundamental chemical property is its ability to split into two charged species, H₃O⁺ (the hydronium ion) and OH⁻ (the hydroxide ion). This reaction defines the pH, a measure of how acidic or alkaline (basic) a solution is, and underpins all of acid-base chemistry, from how enzymes work in your cells to how electrodes function in batteries.

Through this research, the scientists wanted to understand whether (and how) confining water to nanometer-scale spaces affects this behavior.

Advances in materials science are helping unlock secrets of nanomaterials

New instruments on the horizon promise the most precise tools yet to study and experiment on the smallest and most complex materials ever manufactured. In a paper published in the journal Nature Materials, University of Cincinnati assistant professor Hanxun Jin highlighted advances in ultrasensitive technology to measure and manipulate some of the tiniest nanomaterials used in manufacturing, aerospace, medicine and more.

And when Jin says tiny, he means really tiny. Semiconductor nanocrystals called quantum dots that are used in TV screens are so small they’re considered zero-dimensional. That makes the field of nanomaterials characterization a particularly exciting one, Jin said.

Clean crystal surface lets single molecules hit ultimate quantum limit

Scientists at the Max Planck Institute for the Science of Light (MPL) have developed a technique for interrogating molecules on surfaces with spectroscopic precision, thereby reaching the ultimate quantum limit for the first time. With their findings, published in Science, the researchers open new opportunities for the study of molecule-surface interactions and molecular quantum technologies.

Many optical quantum technologies rely on nanoscale objects, such as atoms or molecules, that interact strongly with light. These quantum emitters are used for generating single photons, storing quantum information and entanglement distribution, processes that find application in quantum communication and computation.

To investigate these emitters individually, researchers need to keep them in one place for a long time. This is usually achieved by either trapping them in a vacuum or placing them inside a bulk material. Quantum emitters located on a surface would create new opportunities to manipulate their functionalities by “touching them,” for example, with an atomically sharp tip, as is used in scanning tunneling microscopy (STM) and atomic force microscopy (AFM).

Ultra-fast light-shaping technology could be ‘game-changer’ for future imaging

Scientists have developed a new type of “virtual” metasurface—capable of controlling light in ways traditional lenses and optics can’t—which they say is superior to the current approach, which relies on ultrathin engineered materials. The Nottingham Trent University team says the work will help fully optimize metasurface potential for a range of real-world applications and paves the way for a move from physical to virtual platforms in nanotechnology.

Metasurfaces are many times thinner than a human hair and can bend and focus light, change its color and steer it in different directions, meaning they can replace bulky optical elements in small devices such as lenses, mirrors and filters.

While they are powerful, however, the materials and dimensions of physical metasurfaces are fixed—once built, they can’t change their shape, which can limit how useful they are in real-world technologies.

Copper thin films reveal ballistic electron transport that could reshape future chip wiring

A joint research team has experimentally observed ballistic transport in single-crystalline copper thin films, demonstrating that ballistic transport is achievable in an industry-standard metal at interconnect-relevant dimensions. The study, titled “Ballistic transport in nanodevices based on single-crystalline Cu thin films,” was published in Nature Communications.

Ballistic transport refers to a phenomenon in which electrons travel along straight trajectories without scattering. Until now, this behavior has mainly been observed in special quantum materials such as graphene or semiconductor nanostructures. In copper, where electron scattering is pronounced, realizing ballistic transport has been considered practically impossible.

In this study, the team led by Professor Gil-Ho Lee of the Department of Physics at POSTECH, Professor Emeritus Se-Young Jeong of the School of Transdisciplinary Engineering at Pusan National University and Professor Seong-Gon Kim of the Department of Physics and Astronomy at Mississippi State University, experimentally demonstrated that ballistic transport can occur in structures with a thickness of 80 nm and a linewidth of 150 nm, dimensions comparable to those used in semiconductor interconnects.
