Atomic electron tomography: “A 20-year-old puzzle solved: Researchers reveal the 'three-dimensional vortex' of zero-dimensional ferroelectrics.” This could then be applied to the development of next-generation ultra-high-density memory. A collaborative team, for the first time, experimentally clarified the 3D, vortex-shaped polarization distribution inside ferroelectric nanoparticles in a Nature Communications paper (https://lnkd.in/e-aGwi88). 20 years ago, Prof. Laurent Bellaiche (currently at University of Arkansas) and Prof. Sergey Prosandeev theoretically predicted that a unique form of polarization distribution, arranged in a toroidal vortex shape, could occur inside ferroelectric nanodots. They also suggested that if this vortex distribution could be properly controlled, it could be applied to ultra-high-density memory devices with capacities over 10,000 times greater than existing ones.

Photon-number distributions of various light sources have been studied extensively. However, little is known about the statistical distribution of electrons emitted under the effect of intense light. Researchers at the Max Planck Institute for the Science of Light and FAU Erlangen-Nürnberg led by Prof. Maria Chekhova and Prof. Peter Hommelhoff have now discovered extreme and highly unusual statistical events in electron-number distributions obtained when nanometer-sized metal needle tips are illuminated with ultrashort pulses of bright quantum light. The results prove that the number of electrons is influenced by the light statistics and contributes to a deeper understanding of the process of electron emission. These findings will help to further improve electron microscopes. Learn more 👉 https://lnkd.in/dgZWVwuq #science #research #quantum #optics #statistics 📸  © Stefan Meier

**The Hidden World of Quasi-Crystals: A New Frontier in Material Science** Quasi-crystals, first discovered in 1982 by Dan Shechtman, challenge traditional notions of symmetry in materials science. Unlike regular crystals, which repeat patterns periodically, quasi-crystals exhibit a form of order that is non-repeating yet highly structured. This phenomenon allows for unique properties such as low thermal conductivity and high structural stability. Recent research reveals their potential applications in creating more efficient energy storage systems and advanced coatings. With ongoing studies exploring their role in biomaterials and photonics, quasi-crystals are positioning themselves as a groundbreaking component in the next generation of material science. #MaterialScience #QuasiCrystals #Innovation

Discover CINT Science — As described in an article just published in Nature, the CINT research team designed and fabricated asymmetric, nano-sized gold structures on an atomically thin layer of graphene. The gold structures are dubbed “nanoantennas” based on the way they capture and focus light waves, forming optical “hot spots” that excite the electrons within the graphene. Only the graphene electrons very near the hot spots are excited, with the rest of the graphene remaining much less excited. https://lnkd.in/gRBKUf34

Great for material science: a new microscopy technique is developed👍

UC Irvine scientists have developed a groundbreaking material capable of measuring the temperature of nanoscale objects. This innovative material, InSeI, exhibits remarkable thermal stability and exfoliability, showing promise for use in solution-processable thermal sensors for a wide range of applications. These sensors could be utilized in automotive engine thermal management, cold storage monitoring, and nanothermometry, functioning efficiently at both cryogenic and high temperatures. Moreover, by integrating InSeI into thermochromic devices, temperature detection can be achieved solely through visible light sensing. Through experiments showcasing the material's properties, including the correlation of RGB values to temperature, the potential for InSeI in thermal sensing applications is evident. The material's reversibility of thermochromism, demonstrated through cyclic heating and cooling processes, further highlights its stability and reliability for recurring thermal measurements. The unique electron–phonon coupling in InSeI expands the accessible energy range for optical properties, making it an ideal candidate for thermal measurements with visible light readout. This development represents a significant advancement in the field of thermal sensing technology, with broad implications for diverse industries seeking precise and efficient temperature monitoring solutions.
