  • Patent number: 11894449
    Abstract: Heterostructures include a layer of a two-dimensional material placed on a multiferroic layer. An ordered array of differing polarization domains in the multiferroic layer produces corresponding domains having differing properties in the two-dimensional material. When the multiferroic layer is ferroelectric, the ferroelectric polarization domains in the layer produce local electric fields that penetrate the two-dimensional material. The local electric fields modulate the charge carriers and carrier density on a nanometer length scale, resulting in the formation of lateral p-n or p-i-n junctions, and variations thereof appropriate for device functions.

  • Patent number: 11890598
    Abstract: A supported heterogeneous catalyst material for catalyzing the reverse water-gas shift (RWGS) reaction for the selective formation of CO using an alkali metal-doped molybdenum carbide on a gamma alumina support (A-Mo2C/?-Al2O3, A=K, Na, Li). The A-Mo2C/?-Al2O3 catalyst is synthesized by co-impregnation of molybdemun and alkali metal precursors onto a ?-Al2O3 support. It is then carburized to form the A-Mo2C/?-Al2O3.

  • Patent number: 11885979
    Abstract: High-performance optical-metasurface-based components configured to at frequencies of UV light and, in particular, in deep UV range and performing multiple optical-wavefront-shaping functions (among which there are high-numerical-aperture lensing, accelerating beam generation, and hologram projection). As a representative material for such components, hafnium oxide demands creation and establishment of a novel process of manufacture that is nevertheless based on general principles of Damascene lithography, to be compatible with existing technology and yet sufficient for producing high-aspect-ratio features that currently-used materials and processes simply do not deliver. The described invention opens a way towards low-form-factor, multifunctional ultraviolet nanophotonic platforms based on flat optical components and enabling diverse applications including lithography, imaging, spectroscopy, and quantum information processing.

  • Patent number: 11882023
    Abstract: Methods, and systems, for Multiagent Pathfinding for Non Dynamic Programming Problems, including a CE method which provides for sampling from a complex probability distribution that is not necessarily known in a closed form. The applications of this method include rare-event simulation, variance reduction for estimation problems, and stochastic optimization. The method iteratively searches for a probability distribution that is “close” to the intended distribution, where the closeness of distributions is measured using the Kullback-Liebler (KL) divergence between the distributions. At each step, the method generates samples according to a current candidate distribution from the family. Next, it uses those current candidate distribution samples to move the distribution toward a new candidate distribution that is closer in the sense of KL divergence to the target distribution.
