Glass has been part of human life for thousands of years, from ancient decorations to modern technology like fiber-optic cables.
Now, scientists have found a new way to design a special type of glass that could play an important role in future technologies, including capturing carbon dioxide and storing clean energy gases like hydrogen.
The study, published in Nature Chemistry, focuses on a new kind of material called metal–organic framework glass, or MOF glass.
Unlike traditional glass, which is usually made from sand and minerals, MOF glass is built from metal atoms connected by organic (carbon-based) molecules.
This structure creates tiny spaces inside the material, making it very good at trapping gases and even absorbing water.
One challenge with MOF glass has been that it is difficult to work with. It only softens at very high temperatures, above 300 degrees Celsius, which is close to the point where the material starts to break down.
This makes manufacturing complicated and limits its practical use.
Now, researchers from institutions including University of Birmingham and TU Dortmund University have found a solution inspired by a centuries-old idea from traditional glassmaking.
In regular glass, adding small amounts of certain chemicals can change how the material behaves. The team applied the same principle to MOF glass.
They discovered that adding tiny amounts of chemicals containing sodium or lithium can make a big difference.
These additives lower the temperature at which the glass softens and make it flow more easily when heated. This means the material becomes much easier to shape and process, opening the door to real-world manufacturing.
To understand how this works, scientists used advanced techniques to study the material at the atomic level. They found that sodium does more than just sit inside the glass. Instead, it replaces some of the metal atoms, gently loosening the structure. This makes the glass less rigid and easier to handle, while still keeping its useful properties.
The team also used artificial intelligence and computer simulations to analyze the data and confirm their findings. This combination of experiments and modeling gave them a clear picture of how the material changes when these additives are introduced.
One well-known example of MOF glass is a material called ZIF-62. It can be melted and cooled into a glass while still keeping some of its internal pores. This makes it especially promising for uses such as gas separation, chemical storage, and catalysis.
This discovery provides a new “design rule” for scientists. It shows that MOF glasses can be tuned and engineered in a similar way to traditional glass, allowing researchers to customize them for different purposes.
While more research is needed to improve stability and test these materials in real-world applications, this breakthrough brings MOF glass closer to everyday use.
In the future, these advanced materials could help tackle major challenges such as climate change and clean energy, proving that even something as familiar as glass can still hold surprising new possibilities.
