Aug 23, 2023 (Nanowerk News) A recent UNSW-led paper published in Nature Communications ("Crackling noise microscopy") presents an exciting new way to listen to avalanches of atoms in crystals. The nanoscale movement of atoms when materials deform leads to sound emission. This so-called crackling noise is a scale-invariant phenomenon found...
Ringing protons give insight into early Universe
Aug 22, 2023 (Nanowerk News) In the middle of the last century, physicists found that protons can resonate, much like a ringing bell. Advances over the last three decades have led to 3D pictures of the proton and significant insight into its structure in its ground state. But little is...
‘Topological gardening’ to achieve unexpected spin transport
Aug 22, 2023 (Nanowerk News) ‘Trimming’ the edge-states of a topological insulator yields a new class of material featuring unconventional ‘two way’ edge transport in a new theoretical study from Monash University, Australia (Materials Today Physics, "Extracting unconventional spin texture in two dimensional topological crystalline insulator bismuthene via tuning bulk-edge...
Nanogenerator powered smart food packaging
Aug 22, 2023 (Nanowerk News) Case Western Reserve University researchers are leading the development of a “smart packaging” system to monitor temperature fluctuations, moisture changes and pathogens in perishable food products during transportation. Their energy-efficient approach may offer a more cost-effective supply chain for distributors, savings for food producers and...
New epoxy resin resists flames and reduces waste
Aug 22, 2023 (Nanowerk News) Epoxy resins are tough and versatile polymers. In combination with glass or carbon fibers, they are used, for example, to manufacture components for aircraft, cars, trains, ships and wind turbines. Such epoxy-based fiber-reinforced polymers have excellent mechanical and thermal properties and are much lighter than...
Nano-sized force sensor improves high-precision microscopy
Aug 21, 2023 (Nanowerk News) Recent research in cell biology highlights groundbreaking results. An international team of researchers have recently established a tool they developed to study the mechanics of the cell. The tool can be used to study the inner forces of the cell, for example, the stretching of...
Carbon nanotubes may play a significant role in binding atmospheric carbon dioxide
Aug 21, 2023 (Nanowerk News) Looking at both impacts and the economic outlook, carbon capture and carbon negativity are promising ways in the transition from fossil fuels to green energy, and their role is crucial, since it is not enough to only convert productions towards low carbon technology to mitigate...
Rewriting the past and future of the Universe
Aug 21, 2023 (Nanowerk News) New research has improved the accuracy of the parameters governing the expansion of the Universe. More accurate parameters will help astronomers determine how the Universe grew to its current state, and how it will evolve in the future. It is well established that the Universe...
