  • Patent number: 10611809
    Abstract: A single-domain antibody (sdAb) is produced by causing a bacteria to express the sdAb into cytoplasm of the bacteria, wherein the sdAb is expressed as a fusion protein with the acid tail of ?-synuclein. In embodiments, the protein is free of a periplasmic location tag. Such antibodies have the unexpected ability to refold after thermal denaturation.

  • Patent number: 10600644
    Abstract: Processes for fabricating multi- and monolayer silicene on catalyst metal surfaces by means of plasma-enhanced chemical vapor deposition (PECVD). Silicene is grown by means of PECVD from a starting mixture of H2 and SiH4 having an H2:SiH4 ratio of 100 to 400 on an Ag(111) substrate having a substrate temperature between 20° C. and 290° C., with the deposition being performed for about 10-25 minutes at an RF power between 10 W and 500 W and under a chamber pressure between about 100 mTorr and 1300 mTorr. In most cases, the substrate will be in the form of an Ag(111) film sputtered on a fused silica substrate. A multi-layer silicene film can be formed by extending the deposition time past 25 minutes.

  • Patent number: 10593824
    Abstract: A method for making an ultra-thin, flexible crystalline silicon solar cell from thick, inflexible cells. A thick, inflexible cell having a plurality of electrical contacts on the back side thereof is adhered to a mount by means of a temporary bonding adhesive tape and a thickness of the mounted stack. A thickness of the bonding tape and the back-side contacts is determined and compared to a desired thickness of the final cell. Excess material is ground from the front side of the stack to obtain a thinned stack having the desired thickness and the thinned stack is removed from the mount to produce an ultra-thin, flexible rear-contact Si solar cell having a total thickness of less than 80 ?m and a bending radius of less than 20 mm. The front surface can be textured, with a passivation layer and/or a dielectric layer being deposited thereon.

  • Patent number: 10584988
    Abstract: Embodiments relate to estimating river discharge and depth. Initially, observed velocities are used to generate a maximum velocity streamline for a river section, which is then used with an observed shoreline to construct a streamline curvilinear grid. The grid is used to interpolate scattered velocity data points, which are used with a bottom friction of the river section to approximate mean total head slope values. A least squares minimization scheme is applied to a velocity-slope relationship to estimate a bottom friction and discharge coefficient by fitting a difference in the predicted mean total head elevation values between upstream and downstream ends of the river section to a respective ?-average of the measured total head values of the river section. Discharge of the river section is determined based on the coefficient and a velocity-depth relationship and then used to generate a river forecast.
