In a recent theoretical study, scientists discovered the presence of the Hopfion topological structure in nano-sized particles of ferroelectrics — materials with promising applications in microelectronics and information technology.
New research shows that in the important ceramic material silicon carbide, carbon atoms collect at those grain boundaries when the material is exposed to radiation. The finding could help engineers better understand the properties of ceramics and could aid in fine-tuning a new generation of ceramic materials.
Researchers from Monash, Swinburne and RMIT universities have successfully tested and recorded Australia's fastest internet data speed, and that of the world, from a single optical chip - capable of downloading 1000 high definition movies in a split second.
Cements, clays, soils, inks, paints, and even toothpaste. Many paste materials, also known as dense colloidal suspensions, stiffen as they age. Structural dynamics, or changes in the loads the materials undergo over time, are partly responsible for this change, but for decades, experts have suspected that there’s more going on inside these materials. Now, a University of Delaware professor and an international team of researchers have discovered a process called contact-controlled aging that explains some age-related changes in paste materials.
Researchers from the National University of Singapore have created a new collection of atomically thin two-dimensional materials. Using novel synthesis conditions for transition metal dichalcogenides, more than 10 new materials have been made by the team, with many more still to be discovered.
