A fun fact about using thermoreflectance for measuring thermal conductivity is that it can provide highly detailed and precise measurements at microscopic scales. By monitoring how the reflectivity of a material changes with temperature, researchers can track temperature gradients very accurately. This is especially useful for studying thin films, nanomaterials, or microelectronics, where traditional methods like the hot wire or laser flash technique might not be feasible due to size constraints. What's particularly exciting is that thermoreflectance can measure heat flow in materials as small as a few micrometers, allowing scientists to explore the thermal conductivity of materials at scales that were once unreachable with conventional methods! It's like getting a microscopic view of how heat moves through materials without ever physically touching them.

Exfoliation of Diamond: remarkable and working! A realy GOOD NEWS for the New Year Producing ultrathin diamond membranes for widespread use in technology is up-to now challenging. In a recent paper by Jing et al. (see: Jing, J., Sun, F., Wang, Z. et al. Scalable production of ultra flat and ultraflexible diamond membrane. Nature 636, 627–634 (2024). https://lnkd.in/ewrC7nZG) the authors show that edge-exposed exfoliation using sticky tape is a simple, scalable and reliable method for producing ultrathin and transferable polycrystalline diamond membranes. Their approach enables the mass production of large-area (2-inch wafer), ultrathin (sub-micrometer thickness), ultraflat (sub-nano surface roughness) and ultra flexible (360° bendable) diamond membranes. The membranes show high quality, have a flat workable surface, support standard micromanufacturing techniques, and are  ultra flexible in nature. The authors claim that the quality of the exfoliated membranes depends on the peeling angle and membrane thickness. This single-step method will enable mass production of diamond membranes. This is expected to accelerate the commercialization and arrival of the diamond era in electronics, photonics and other related fields.

New Technique Enables Mass Production of Metal Nanowires. by Riko Seibo - Tokyo, Japan (SPX) Mass production of metal nanowires possible by breakthrough technique.  Researchers at Nagoya University in Japan have developed a new method for producing metal nanowires (NWs) that could enable their mass production for next-generation electronics. The breakthrough technique addresses challenges in scaling up the production of pure metal NWs, making them more practical for use in advanced electronic devices, including circuits, LEDs, and solar cells. Their findings were published in the journal 'Science'. Until now, mass production of NWs has been hindered by difficulties in maintaining both quality and purity during scaling. Typically, NWs are created by transporting atoms in a gas phase state, but this process has proven particularly challenging for metals, limiting their use in electronic components. To address this issue, a team led by Yasuhiro Kimura from Nagoya University's Graduate School of Engineering employed a process called atomic diffusion, facilitated in a solid phase state and enhanced by ion beam irradiation, to create aluminum NWs from single crystals. Atomic diffusion, which involves atoms moving from high concentration areas to low concentration areas due to changes in stress and temperature, was key to this technique. The researchers used ion beams to irradiate crystal grains inside thin aluminum films, causing them to coarsen at the surface. This changed the stress distribution, directing the flow of atoms and creating a feedstock for NW growth. When heat was applied, atoms moved upward from the fine grains at the bottom to the coarser grains at the top, leading to the large-scale production of NWs. "We increased the density of aluminum NWs from 2x105 NWs per square cm to 180+ 105 per square cm," Kimura explained. "This achievement paves the way for bottom-up metal NW growth methods, which have so far been grown only accidentally and in small quantities. It can also be extended to other metals in principle." The produced aluminum NWs have several potential applications, particularly as nanocomponents for sensing devices and optoelectronics, due to their large surface area, strong mechanical properties as single crystals, and resistance to natural oxidation. https://lnkd.in/dPe5WYYr
