Summary: Researchers from Chalmers University of Technology, Sweden have discovered a way to make a new insulating material 3 times more insulating for high voltage direct current cables or HVDC cables. The way they have found is quite novel and can be used commercially easily. The researchers believe that this could lead to a new field of research. Image cred: Chalmers University of Technology

Summary: Researchers from USF, collaborating with Princeton University and Zhejiang Sci-Tech University have discovered that glassy polymers are not all glassy. Apparently, if you see at a nanoscale level, there exists a rubbery layer on the surface. They have figured out how to control this layer “for important properties such as adhesion and scratch resistance, even on rigid surfaces”. This breakthrough paves way for better products such as improved batteries, cellphone screens and automobile paint.

Summary: In Material Science, glass describes any substance with disordered structure and not just your typical window glass. Researchers from Yanshan University have recently discovered how to make a glass harder than diamond while experimenting around with some buckyballs(C60). To put this in context, “Scratching another diamond might require somewhere between 60 and 100 gigapascals, depending on whether it's natural or made with care in a lab. The glassy material AM-III measured somewhere between 110 and 116 gigapascals on the Vickers hardness test, making it the hardest amorphous solid to date.” AM-III leaving its mark on a diamond (Zhang, et al., National Science Review, 2021)

Summary: Conventional methods to produce thin films of metals such as Platinum, Iridium and Tungsten which are used in the semiconductor and energy industry are expensive and energy consuming. Researchers from the University of Minnesota have developed a way to lower the temperature from several thousands to less than 200 degrees effectively using organic ligands. “"Bringing down the cost and complexity of metal deposition while also allowing for deposition of more complex materials like oxides will play a large role in both industrial and research efforts," said William Nunn, a University of Minnesota chemical engineering and materials science graduate student, the paper's first author, and a recipient of the department's Robert V. Mattern Fellowship.” Image cred: https://phys.org/news/2021-08-technology-important-metals-efficiently.html
