  • Publication number: 20190119331
    Abstract: A system and method for controlling metabolic enzymes or pathways in cells to produce a chemical above the levels of a wild-type strain is disclosed. The system utilizes cells, including yeasts, bacteria, and molds, having at least two genes capable of being controlled bi-directionally with light, where one gene is turned from off to on when exposed to light and another gene is turned from on to off when exposed to light, the two genes reversing when the light is turned off. Cells may utilize any number of sequences that benefit chemical production, including sequences that: encode for constitutive transcription of light-activated transcription factor fusions; encode for a metabolic enzyme; encode for a repressor; induce expression of metabolic enzymes; and an endogenous or exogenous activator expressed by a constitutive promoter, inducible promoter, or gene circuit.

  • Publication number: 20190100852
    Abstract: A method for the electrohydrodynamic deposition of carbonaceous materials utilizing an electrohydrodynamic cell comprising two electrodes comprised of a conductive material, by first combining a solid phase comprising a carbonaceous material and a suspension medium, placing the suspension between the electrodes, applying an electric field in a first direction, varying the intensity of the electric field sufficiently to drive lateral movement, increasing the electrical field to stop the lateral transport and fix the layers in place, then removing the applied field and removing the electrodes. Among the many different possibilities contemplated, the method may advantageously utilize: varying the spacing between the electrodes; removing the buildup from one or both electrodes; placing the electrodes into different suspensions; adjusting the concentration, pH, or temperature of the suspension(s); and varying the direction, intensity or duration of the electric fields.

  • Patent number: 10246539
    Abstract: This invention relates generally to the field of quasicrystalline structures. In preferred embodiments, the stopgap structure is more spherically symmetric than periodic structures facilitating the formation of stopgaps in nearly all directions because of higher rotational symmetries. More particularly, the invention relates to the use of quasicrystalline structures for optical, mechanical, electrical and magnetic purposes. In some embodiments, the invention relates to manipulating, controlling, modulating and directing waves including electromagnetic, sound, spin, and surface waves, for pre-selected range of wavelengths propagating in multiple directions.

  • Patent number: 10239012
    Abstract: Disclosed herein are new methods, machines, processes, and systems for separating molecules by determining better materials and process optimization conditions. As a result of these advances, this disclosure provides improved carbon dioxide capture, better flue gas treatments, and more efficient methods of purifying gases have been developed. Optimal sorbents can be obtained by using a computational screening method that selects microporous structures (e.g. zeolites and metal-organic frameworks) from a database of materials with the greatest potential for cost-effective separations. The disclosed methods are the first to consider both the size and shape of the adsorbent material. This is also the first disclosure to consider the process application and cost when selecting which material to use.

  • Patent number: 10229068
    Abstract: An approach to implementing or configuring an Oblivious RAM (ORAM), which in addition to behaving as a RAM, provides a way to meet a specified degree of privacy in a manner that avoids applying unnecessary computation resources (computation time and/or storages space and/or data transfer) to achieve the specified degree of privacy. In this way, a tradeoff between privacy and computation resources may be tuned to address requirements of a particular application. This ability to tune this tradeoff is not found in other ORAM implementations, which in general aim to achieve complete privacy. In some implementations, the ORAM provides a constant bandwidth overhead compared to conventional RAMs, while achieving a statistical privacy as desired by the user.

  • Publication number: 20190040107
    Abstract: Provided are astexin-1, astexin-2 and astexin-3 lasso peptides, which are based on sequences identified in Asticcacaulis excentricus, and methods of making and using same. Astexin-1 is highly polar, in contrast to many lasso peptides that are primarily hydrophobic, and has modest antimicrobial activity against Caulobacter crescentus, a bacterium related to Asticcacaulis excentricus. The solution structure of astexin-1 was determined, revealing a unique topology that is stabilized by hydrogen bonding between segments of the peptide. Astexins-2 and -3 are intracellular lasso peptides.

  • Patent number: 10175389
    Abstract: The invention provides an article of manufacture, and methods of designing and making the article. The article permits or prohibits waves of energy, especially photonic/electromagnetic energy, to propagate through it, depending on the energy band gaps built into it. The structure of the article may be reduced to a pattern of points having a hyperuniform distribution. The point-pattern may exhibit a crystalline symmetry, a quasicrystalline symmetry or may be aperiodic. In some embodiments, the point pattern exhibits no long-range order. Preferably, the point-pattern is isotropic. In all embodiments, the article has a complete, TE- and TM-optimized band-gap. The extraordinary transmission phenomena found in the disordered hyperuniform photonic structures of the invention find use in optical micro-circuitry (all-optical, electronic or thermal switching of the transmission), near-field optical probing, thermophotovoltaics, and energy-efficient incandescent sources.
