Uppsala University, Sweden
A breakthrough in material science has taken place at Uppsala University in Sweden, where researchers have created what was once considered an "impossible" material. This new substance, known as Upsalite, is the most porous material ever developed, with a surface area of up to 800 square meters per gram. Its remarkable absorbent properties have sparked excitement across multiple industries. The findings were recently published in the Public Library of Science (PLOS).
Scientists believe that Upsalite could revolutionize several fields, from reducing energy use in humidity control systems to improving drug formulation and warehouse climate management. It also holds potential for environmental applications, such as capturing toxic waste, oil leaks, and even controlling odors in sanitation and fire suppression systems.
The material is a form of amorphous magnesium carbonate, which had long been thought impossible to produce without water. However, through a simple cryogenic process, the team at Uppsala successfully synthesized it. This discovery marks a significant shift in how scientists view the synthesis of such materials.
According to John Gomz de la Tor, a researcher from the Department of Nanotechnology and Functional Materials, the discovery was somewhat accidental. In 2011, while experimenting with a previous method, they left more than three substances in the reactor due to an error. This led to the formation of a hard, glue-like substance. After drying and extensive analysis over the next year, they finally produced what was once deemed unattainable.
What makes Upsalite unique is its ultra-high surface area and nano-sized pores, less than 10 nanometers in diameter. These features allow it to interact with its environment in highly efficient ways. For instance, when humidity is low, it can absorb more moisture than any other existing material. This makes it one of the top-performing materials in the category of high-surface-area breathable materials, alongside mesoporous silica, zeolites, metal-organic frameworks, and carbon nanotubes.
Malila Stom, the head of the nanotechnology and functional materials department, highlighted that Upsalite's distinct properties open new doors for sustainable industrial applications. With its versatility and efficiency, this material could pave the way for innovative solutions in energy, healthcare, and environmental protection.
