Magnetite Nanoparticles: Synthesis and Applications in Optics and Nanophotonics

Magnetite nanoparticles with different surface coverages are of great interest for many applications due to their intrinsic magnetic properties, nanometer size, and definite surface morphology. Magnetite nanoparticles are widely used for different medical-biological applications while their usage in optics is not as widespread. In recent years, nanomagnetite suspensions, so-called magnetic ferrofluids, are applied in optics due to their magneto-optical properties. This review gives an overview of nanomagnetite synthesis and its properties. In addition, the preparation and application of magnetic nanofluids in optics, nanophotonics, and magnetic imaging are described

Magnetic memory and spontaneous vortices in a van der Waals superconductor

Magnetic memory and spontaneous vortices in a van der Waals superconductor Tue, 02/08/2022 - 12:00

Doped Mott insulators exhibit some of the most intriguing quantum phases of matter, including quantum spin liquids, unconventional superconductors and non-Fermi liquid metals1–3 . Such phases often arise when itinerant electrons are close to a Mott insulating state, and thus experience strong spatial correlations. Proximity between diferent layers of van der Waals heterostructures naturally realizes a platform for experimentally studying the relationship between localized, correlated electrons and itinerant electrons. Here we explore this relationship by studying the magnetic landscape of tantalum disulfde 4Hb-TaS2, which realizes an alternating stacking of a candidate spin liquid and a superconductor4 . We report on a spontaneous vortex phase whose vortex density can be trained in the normal state. We show that time-reversal symmetry is broken in the normal state, indicating the presence of a magnetic phase independent of the superconductor. Notably, this phase does not generate ferromagnetic signals that are detectable using conventional techniques. We use scanning superconducting quantum interference device microscopy to show that it is incompatible with ferromagnetic ordering. The discovery of this unusual magnetic phase illustrates how combining superconductivity with a strongly correlated system can lead to unexpected physics.

Excellence in Business to Business Electronic Technologies - ZERO EC

Excellence in Business to Business Electronic Technologies - ZERO EC Wed, 30/06/2021 - 12:00

Bar Ilan Institute of Nanotechnology and Advanced Materials (BINA), Ramat Gan, Israel – created in an unexpected speed a prototype that will revolutionize the approach used in semiconductors. It took only 24 months to come out with the first attempt to combine Zero EC technology within Silicon (a patented technology).

The technology allows electrons to be guided in vacuum, reducing the energy dissipated in the tube to practically zero regardless of the distance (about 10-4 pJ/bit in total). The transfer of data is faster; the usable bandwidth is increased considerably (x1000). In contrary to its homonym, copper that heats and fiber optics that is expensive, this technology feels like an energy boost. The improvements are numerous and permitting a bright future for the semi conducting industry.

Nanotechnology: Good Things Come in Small Packages

Nanotechnology: Good Things Come in Small Packages When scientists split the atom, there was sure to be a reaction. Some began wondering “What do we do with the pieces?” Curiosity is the soul of discovery. Playing with those pieces has resulted in life-enhancing breakthroughs, from clothing to medicine. And no one knows what might come next.
