A research team has devised a novel method to prepare carbonized polymer nanodots capable of emitting multi-color ultra-long room-temperature phosphorescence (RTP) from blue to green.

Ferroelectric binary oxides thin films are garnering attention for their superior compatibility over traditional perovskite-based ferroelectric materials. Its compatibility and scalability within the CMOS framework make it an ideal candidate for integrating ferroelectric devices into mainstream semiconductor components, including next-generation memory devices and various logic devices such as Ferroelectric Field-effect Transistor, and Negative Capacitance Field-effect Transistor.

An international research team led by the University of Göttingen has demonstrated experimentally that electrons in naturally occurring double-layer graphene move like particles without any mass, in the same way that light travels. Furthermore, they have shown that the current can be "switched" on and off, which has potential for developing tiny, energy-efficient transistors—like the light switch in your house but at a nanoscale.

To save on fuel and reduce aircraft emissions, engineers are looking to build lighter, stronger airplanes out of advanced composites. These engineered materials are made from high-performance fibers that are embedded in polymer sheets. The sheets can be stacked and pressed into one multilayered material and made into extremely lightweight and durable structures.

In recent years, the adherence of microorganisms to surfaces or coatings has created major health risks to humans. Among these, microbial attachment and growth on surgical suture lines accounts for more than 20% of health-related infections in patients.

For the first time, scientists have managed to create sheets of gold only a single atom layer thick. The material has been termed goldene. According to researchers from Linköping University, Sweden, this has given the gold new properties that can make it suitable for use in applications such as carbon dioxide conversion, hydrogen production, and production of value-added chemicals. Their findings are published in the journal Nature Synthesis.

A recent UCLA study demonstrates a new process for screening T cells, part of the body's natural defenses, for characteristics vital to the success of cell-based treatments. The method filters T cells based on the receptor proteins found on their surface—which enable them to latch onto certain threats—and the type and amount of cell-killing or immune response-triggering molecules that they secrete.

Researchers from the National University of Singapore (NUS) have developed a new design concept for creating next-generation carbon-based quantum materials, in the form of a tiny magnetic nanographene with a unique butterfly-shape hosting highly correlated spins. This new design has the potential to accelerate the advancement of quantum materials which are pivotal for the development of sophisticated quantum computing technologies poised to revolutionize information processing and high density storage capabilities.

An afterglow luminescent nanoprobe opens up new possibilities for imaging living cells. As a research team reports in the journal Angewandte Chemie International Edition, their new "nanotorch" can continue to luminesce for more than 10 days after a single excitation.

The accumulation of plastic waste in natural environments is of utmost concern, as it is contributing to the destruction of ecosystems and is causing harm to aquatic life. In recent years, material scientists have thus been trying to identify all-natural alternatives to plastic that could be used to package or manufacture products.

Microplastics pose a great threat to human health. These tiny plastic debris can enter our bodies through the water we drink and increase the risk of illnesses. They are also an environmental hazard; found even in remote areas like polar ice caps and deep ocean trenches, they endanger aquatic and terrestrial lifeforms.

A team of uOttawa Faculty of Medicine researchers have developed a path to a biomanufacturing process that could potentially transform how Canada generates immunotherapeutic materials—specifically natural killer cells and extracellular vesicles (EVs)—to fuel tomorrow's novel cancer treatments.

For years, scientists have been intrigued by how molecules move across surfaces. The process is critical to numerous applications, including catalysis and the manufacturing of nanoscale devices.

A study of oxygen molecules interacting with atomically thin layers of materials being developed as new generations of semiconductors could significantly improve control over the fabrication and applications of these two-dimensional (2D) materials.

New options for making finely structured soft, flexible and expandable materials called hydrogels have been developed by researchers at Tokyo University of Agriculture and Technology (TUAT).

Understanding water behavior in nanopores is crucial for both science and practical applications. Scientists from City University of Hong Kong (CityU) have revealed the remarkable behavior of water and ice under high pressure and temperature, and strong confinement.

Left unchecked, corrosion can rust out cars and pipes, take down buildings and bridges, and eat away at our monuments. Corrosion can also damage devices that could be key to a clean energy future. And now, Duke University researchers have captured extreme close-ups of that process in action.

Voids, or empty spaces, exist within matter at all scales, from the astronomical to the microscopic. In a new study, researchers used high-powered microscopy and mathematical theory to unveil nanoscale voids in three dimensions. This advancement is poised to improve the performance of many materials used in the home and in the chemical, energy and medical industries—particularly in the area of filtration.

Medicine can help to treat certain illnesses; for example, antibiotics can help overcome infections, but a new, promising field of medicine involves providing our body with the "blueprint" for how to defeat illnesses on its own.

In an article published in Nature Communications, an international team led by researchers from the Nanodevices group at CIC nanoGUNE succeeded in voltage-based magnetization switching and reading of magnetoelectric spin-orbit nanodevices. This study constitutes a proof of principle of these nanodevices, which are the building blocks for magnetoelectric spin-orbit (MESO) logic, opening a new avenue for low-power beyond-CMOS technologies.
