Deicing technologies often rely on heat to melt ice. But University of Texas at Dallas researchers have found that, under extreme cold, making ice even colder can weaken its grip on surfaces.

Storing energy as heat is a proven pathway to address the challenge solar power faces when it's dark or cloudy outside by enabling the capture, storage and on-demand release of thermal energy. The process, called high-temperature thermal energy storage (TES), however, can be prohibitively expensive.

A new stretchable quantum-dot light-emitting diode (QLED) delivers incredibly high resolution while producing record brightness that can be clearly viewed even outside in direct sunlight.

In a recent paper published in Nature Nanotechnology, Korean researchers unveiled a new QLED material with applications far beyond televisions, stretching into many future daily-use technologies.

This new QLED can stretch in every direction, just like organic skin, making it extremely useful in future wearable applications and as a covering for soft robots. Unlike earlier attempts to make a stretchable QLED, this one doesn’t lose picture quality when it stretches, delivering high resolution and extreme brightness under tension.

QLED Explained

For most of us, QLEDs are familiar as one of the technologies available in modern televisions. Conventional QLED TVs use quantum dots—nanoscale semiconductor crystals—to help produce exceptionally bright and vivid colors. OLED displays, by comparison, use self-emissive pixels that can switch off individually, allowing them to produce deeper blacks. While OLEDs perform particularly well in dark viewing environments, the high brightness achievable with quantum-dot displays can make them especially well-suited for brightly lit environments.

Despite the technology’s suitability for the bright world around us rather than just darkened environments, major challenges remained in producing a stretchable version. Early attempts addressed the problem by allowing the wiring to stretch while the light-emitting pixels remained unchanged in size. This meant that as the material expanded, its effective resolution dropped because the same number of pixels became spread across a wider area, much like enlarging a low-resolution digital image.

Building on these efforts, some researchers attempted to replace conventional materials with more stretchable alternatives, but these tended to make achieving high resolutions and efficiently moving electrical charge through the material difficult. As a result, these systems produced dimmer, lower-resolution images, limiting their utility.

A New Process

The researchers developed a new fabrication approach to address some of the major problems facing stretchable QLED technology. Central to their innovation is the use of an elastic polymer incorporating MPA as a ligand, or bonding molecule. This approach improves charge injection efficiency while helping eliminate the image stretching and smearing that have affected previous stretchable displays.

Using this new process, the researchers produced a display with a resolution of about 16,000 pixels per inch, with features spaced at roughly 700 nanometers. Red, green, and blue emissive layers can also be precisely arranged, allowing the stretchable material to produce full-color images.

Testing a New QLED

In tests, the team’s new QLED proved to be a major advance. They successfully stretched the material to 1.65 times its original size with no damage to its light-emitting performance. Additionally, their stretchable QLEDs were the brightest ever tested at 53,300 nits, more than triple the brilliance of prior attempts.

Based on these tests, the researchers see numerous future applications for their material in extended reality devices, soft robots, electronic skin, wearable technologies, health care, and automotive displays. 

“We resolved both the drop in resolution and the limits on light-emitting performance, which had been the biggest challenges for stretchable displays, and secured core technology for commercialization,” concluded co-author Professor Moon Kee Choi of Ulsan National Institute of Science and Technology in Korea. “It will be used widely as a manufacturing platform for various next-generation soft devices, including wearables and electronic skin.”

The paper, “High-Resolution Intrinsically Stretchable Quantum-Dot Displays Through Thermally Assisted Intaglio Transfer Printing,” appeared in Nature Nanotechnology on September 14, 2026.

Corrosion is a major concern for aging steel bridges because progressive material loss can affect their long-term serviceability and, in severe cases, structural safety. Visual inspection remains indispensable for assessing bridge condition, but inspectors must evaluate corrosion under widely varying conditions, including differences in lighting, coating color, shadows, surface deposits, structural geometry and accessibility. These factors can make consistent corrosion assessment challenging.

Researchers at the Department of Energy's (DOE) Oak Ridge National Laboratory (ORNL) developed a new type of monitor that can check every minute or even every second for the buildup of nuclear material in the air ducts of nuclear fuel cycle facilities, promoting high standards of safety and security.

Scientists have used an X-ray detector on a sounding rocket, a type of research rocket that flies to the edge of space, then returns to Earth within minutes, to document metal dendrites—the branching structures that form as liquid metal cools—forming in microgravity conditions for the first time. By analyzing the images using machine learning, they reveal insights that could improve how metal components are solidified and manufactured.

Radar technology is one of the most powerful tools for better understanding the world around us. Researchers use radar to see beneath the surface of ice, forest canopies or soil in ways the human eye never could. As the planet changes, that capability matters more than ever.

Today’s chatbots aren’t likely to help lone actors invent a deadly pathogen, experts say. But newer models, trained in biology, may need stronger safeguards.

Billions of people still suffer from hunger and food insecurity worldwide. Meanwhile, microbial contamination causes a third of global food waste annually, resulting in major economic losses and illnesses. Although antibiotics and pesticides help control contamination, their excessive use can promote bacterial resistance or leave toxic residues. 

One alternative uses materials that generate highly reactive forms of oxygen when exposed to light, called photocatalysts, to prolong food freshness. These molecules kill bacteria by damaging their cell components in a process called photodynamic inactivation or PDI. However, current PDI systems rely on energy-intensive lasers and long exposure times because the bacteria’s protective cell membranes block reactive oxygen molecules. As a result, the systems don’t kill bacteria effectively and risk overheating food, affecting its freshness and nutritional value.

Scientists at Zhejiang University in China thought that it would be possible to achieve a PDI system using accessible, free sunlight with the right photocatalyst. Moreover, they also wanted to integrate this photocatalyst into food packaging to combat microbes during storage. 

To make the photocatalyst, the researchers mixed water with a glue-like plant fiber that provides structural support, called pectin, and a chemical from plant seeds that supplies phosphorus, called phytic acid. Then they heated the mixture in a sealed reactor at 220ºC (428ºF) for 5 hours to form tiny structures composed of a carbon core surrounded by a phosphorus-rich shell called phosphorus-modified carbonized polymer dots or PCDs.

To incorporate the PCDs into film packaging, the researchers dissolved equal amounts of a plant fiber from konjac, called glucomannan, and another plant-derived molecule, called carboxymethylcellulose, in warm water to form a network of entangled molecular chains. Then, they added 1.5 milligrams of PCD per milliliter to this mixture, which linked the chains together like molecular fasteners. Finally, they added a moisture-binding chemical called glycerin to prevent brittleness. The researchers cast this mixture onto separate Petri dishes and dried them, forming thin, plastic-like PCD films.

To test the films, the researchers placed Escherichia coli bacteria between 2 sterilized film sheets and exposed the samples to either darkness or simulated sunlight for 20 minutes. They then transferred the microbes onto agar plates and incubated them for 15 hours, allowing surviving bacteria to form visible colonies. They compared the number of bacterial colonies with those of untreated samples to calculate the percentage of bacteria the films eliminated in each environment. 

Tests under darkness showed that the films eliminated about 60% of the bacteria. The researchers attributed this result to the positive electrical charge of PCDs, which attracts the bacteria’s negatively charged cell surfaces. The electrical attraction stresses their cell membranes, interfering with essential life processes. This result suggested that the films use a separate charge-based antibacterial mechanism apart from PDI, which requires light to work.

Under simulated sunlight, the films eliminated nearly 100% of the bacteria. The researchers identified 2 principal mechanisms causing this. First, the PCDs acted as tiny heaters that generated localized heat, which stretched holes in the bacterial membranes, allowing contents to leak out of their cells through a process called photoporation. Second, the PCDs generated reactive oxygen molecules that could then penetrate the bacteria. Once inside the cells, these molecules irreversibly damage the bacteria’s internal components and genetic material through PDI. 

The researchers also investigated whether PCD films could serve as food packaging by using them to wrap fresh strawberries. Compared with conventional nonbiodegradable polyethylene packaging where visible rotting occurred, the PCD films kept the strawberries fresh for more than 4 days by suppressing bacterial growth and regulating moisture levels. When the team tested whether the films were toxic, they found that the films are safe for humans and compatible for food applications. They also buried the films in soil for 24 days and found that they degraded by 78%, demonstrating biodegradability suitable for packaging fresh foods.

The team concluded that PCD films could be a biodegradable food packaging that combines plant-based materials with multiple antibacterial strategies. The films retained antibacterial activity in darkness and became more effective under sunlight through the combined effects of photoporation and PDI. These findings demonstrated that by combining multiple mechanisms into a single material, researchers can create multifunctional food packaging that remains effective across different storage conditions.
