The Meissner Effect Mapped at High Pressure

A new data-analysis method allows researchers to visualize a superconductor expelling an applied magnetic field under high-pressure conditions. [...] Except in limited regions, magnetic fields cannot penetrate a superconductor―a phenomenon known as the Meissner effect. Researchers routinely make use of this effect to detect defects in the material, which are sites that can trap the magnetic field. However, some materials require high pressures to be coerced into superconducting states, making magnetic-field measurements impractical. Now Cassandra Dailledouze from the University of Paris-Saclay and her colleagues have mapped a magnetic field contorting around a superconductor under a pressure of 4 gigapascals [1]. Their result was made possible by the development of a fast and robust data-analysis method.

AI pinpoints promising materials that capture only CO₂ from air

In order to help prevent the climate crisis, actively reducing already-emitted CO₂ is essential. Accordingly, direct air capture (DAC)—a technology that directly extracts only CO₂ from the air—is gaining attention. However, effectively capturing pure CO₂ is not easy due to water vapor (H₂O) present in the air. KAIST researchers have successfully used AI-driven machine learning techniques to identify the most promising CO₂-capturing materials among metal-organic frameworks (MOFs), a key class of materials studied for this technology. The research team, led by Professor Jihan Kim from the Department of Chemical and Biomolecular Engineering, in collaboration with a team at Imperial College London, published their research in the journal Matter.

Decoding thermal behavior in crystals: Insights from thalidomide

Understanding how molecular arrangements within crystals influence their thermal behavior is a fundamental question in solid-state chemistry. This topic is especially relevant in pharmaceuticals existing as enantiomers, molecules in two forms that are mirror images of one another but cannot be superimposed, which can exhibit distinct physical and chemical properties depending on their crystalline form. Thalidomide is a notable example. Initially introduced as a sedative, it was withdrawn due to its devastating effects on embryos. However, in recent years, thalidomide has regained clinical importance as a treatment for conditions such as multiple myeloma and leprosy. Despite this renewed relevance, the physicochemical behavior of thalidomide in the solid state remains insufficiently explored.

Near-perfect defects in 2D material could serve as quantum bits

Scientists across the world are working to make quantum technologies viable at scale—an achievement that requires a reliable way to generate qubits, or quantum bits, which are the fundamental units of information in quantum computing. The task has so far remained elusive, but one of the materials that has garnered a lot of attention as a possible qubit platform is hexagonal boron nitride (h-BN), a 2D material that can host solid-state single-photon emitters (SPEs). Like the name indicates, SPEs are atomic structures in solid materials that can produce individual photons. In a new study published in Science Advances, researchers at Rice University and collaborators at Oak Ridge National Laboratory and the University of Technology, Sydney report the first demonstration of low noise, room-temperature quantum emitters in h-BN made through a scalable growth technique.

Simple table salt enhances new adhesive polymer technology

Adhesives are everywhere, from the tape used in households to the bonding materials in vehicles and electronics. The search for stronger, more adaptable adhesives is ongoing and may come down to adding a dash of salt to two special polymer ingredients known as polyzwitterions, or PZIs. New research from a FAMU-FSU College of Engineering team led by Hoyong Chung, an associate professor in the Department of Chemical and Biomedical Engineering, shows a new way to create adhesives by using the natural attraction between positively and negatively charged materials. The work was recently published in the Journal of the American Chemical Society. "We want to create stronger and more versatile adhesives using a strategy involving electrostatic interactions," Chung said. "Our research centers around two special polymers, known as PZIs, with the goal of getting them to bond more effectively."

Low-cost method removes micro- and nanoplastics from water

Researchers at the University of São Paulo (USP) in Brazil have developed a novel nanotechnology-based solution for the removal of micro- and nanoplastics from water. Their research is published in the journal Micron. Tiny plastic particles are ubiquitous in the world today and may currently be one of the most important environmental problems, after the climate emergency and the accelerating extinction of species and ecosystems. Microplastics are in the soil, water and air, and in the bodies of animals and humans. They come from everyday consumer goods and from wear-and-tear on larger materials. They are found everywhere and in every kind of environment. A major source is the water used to wash clothes made of synthetic fibers. Microplastics currently cannot be filtered out of wastewater and eventually penetrate the soil, water table, rivers, oceans and atmosphere.

There comes a time in your life when you accept and acknowledge your quirkiness, but you still want to pursue that behavior.

Not because the deviation triggers anxiety, but because you are so close to 30, you have developed your own conformity.. perhaps the first sign for Uncliyat is brewing !?!?!

Modeling system could enable future generations of self-sensing materials

Research that eliminates the guesswork in developing advanced 3D printed materials could help accelerate the development of new forms of "self-sensing" airplanes, robots, bridges and more. A team of engineers led by researchers from the University of Glasgow have developed the first system capable of modeling the complex physics of 3D-printed composites capable of detecting strain, load, and damage using nothing more than a measure of electrical current. By allowing material scientists to predict in advance for the first time how new structures can be fine-tuned to produce specific combinations of strength, stiffness, and self-sensing properties, it could help catalyze the development of revolutionary new applications for the technology.

Quality control: Neatly arranging crystal growth to make fine thin films

Table salt and refined sugar look white to our eyes, but that is only because their individual colorless crystals scatter visible light. This feature of crystals is not always desirable when it comes to materials for optical and electrical devices, however. Metal-organic frameworks are one such material. Crystalline with micropores, thin films of these nanomaterials have been attracting attention as a next-generation material that could also have an impact on environmental issues such as hydrogen storage and carbon dioxide capture. An Osaka Metropolitan University Graduate School of Engineering team has found a way to control the growth of crystals on such thin films so that light scattering is reduced significantly.

3D-printed blood vessels bring artificial organs closer to reality

Growing functional human organs outside the body is a long-sought "holy grail" of organ transplantation medicine that remains elusive. New research from Harvard's Wyss Institute for Biologically Inspired Engineering and John A. Paulson School of Engineering and Applied Science (SEAS) brings that quest one big step closer to completion. A team of scientists has created a new method to 3D-print vascular networks that consist of interconnected blood vessels possessing a distinct "shell" of smooth muscle cells and endothelial cells surrounding a hollow "core" through which fluid can flow, embedded inside a human cardiac tissue. This vascular architecture closely mimics that of naturally occurring blood vessels and represents significant progress toward being able to manufacture implantable human organs.

Understanding the forces that regulate crystallization by particle attachment

A complex interplay of energetics and dynamics governs the behavior of nanocrystals in solution. These dynamics are usually interpreted in terms of the theory developed by Derjaguin, Landau, Verwey, and Overbeek (DVLO), and understanding these forces is particularly important for controlling oriented attachment (OA), where individual nanocrystals fuse together in specific alignments. In a new study published in ACS Nano, researchers explored the effects of forces not accounted for in DLVO theory on a zinc oxide (ZnO) model system undergoing OA. They found that the driving forces behind the attachment are dipole–dipole forces that are not considered in DLVO theory. The dipole forces lead to faster attachment in less polar solutions, validated by calculations that account for non-DLVO forces. The researchers also showed that the short range, repulsive forces that slow attachment depend on the nature of the solvent, particularly its molecular packing and intermolecular interactions.

Researchers use plant-inspired polymers for water purification

Clean drinking water is a basic demand for our health and well-being. However, as the global population grows, achieving this for all communities worldwide becomes more challenging. Now, in a study published in Nature Communications, researchers from the HeKKSaGOn Alliance, which involved scientists from Kyoto University, Osaka University and Heidelberg University (Germany), have taken inspiration from a protein found in plants, creating a new way to remove harmful heavy-metal ions from water. Although current water-purification methods are effective for the large volumes of water involved, they are generally not specific for heavy-metal ions. This means that they also remove ions that are not harmful, making these methods less efficient.
