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.
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.
Stanford researchers may have just opened the door to a future where quantum technology no longer depends on multi-million-dollar cryogenic systems.
In this video, we break down Stanford University’s groundbreaking 2025 research that demonstrated room-temperature photon-electron quantum entanglement on a silicon-compatible chip. While this is not yet a full quantum computer, it represents a major step toward solving one of the biggest challenges in quantum technology: the extreme cooling requirements that have limited quantum systems for decades.
We’ll explore how twisted light, molybdenum diselenide (MoSe₂), valley states, and silicon nanostructures work together to create stable quantum interactions without dilution refrigerators operating near absolute zero. You’ll also learn what this breakthrough means for the future of quantum computing, quantum communication, quantum cryptography, and the emerging quantum internet.

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).
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.
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.
McGill University researchers have developed a light-detecting nanoscale structure that mimics how a neuron processes information. The neuron-like behavior emerges from the materials themselves, reducing the energy demand associated with similar devices that rely on circuits or software.
Instead of capturing data first and processing it elsewhere, the device senses and interprets light in the same place, similar to how the eye processes visual information.
The researchers say the discovery could increase the efficiency of vision-based technologies like artificial retinas and smart optical sensors. It could also transform how artificial neural networks (ANNs), a foundation of machine learning, are built. The research is published in the journal Nanoscale.
Researchers at Oregon State University have potentially found a new way to treat the most aggressive form of brain cancer, glioblastoma, whose two-year survival rate is less than 30%.
The study, led by Oleh Taratula, Olena Taratula and Yoon Tae Goo of the OSU College of Pharmacy, addresses what they describe as the two most persistent obstacles to effective glioblastoma treatment: delivering therapeutic agents through the blood-brain barrier, the cell network that acts as a security checkpoint between the bloodstream and the central nervous system, and then getting those agents to preferentially target tumors.
In research published in the Journal of Controlled Release, the scientists demonstrate the novel treatment technique in a mouse model. They loaded lipid nanoparticles with genetic material that promotes tumor suppression, then coated the nanoparticles with a type of sugar. The result was a 50% median increase in glioblastoma survival time.
