  • ULTRASONIC INJECTION DEVICE
    Publication number: 20240082870
    Abstract: An ultrasonic injection device and methods of use are presented. The ultrasonic injection device comprises a housing, an injection nozzle attached to the housing, an ultrasonic vibration generator attached to the housing, and a pressure applicator. The injection nozzle has a number of openings configured to dispense a fluid. The ultrasonic vibration generator is configured to apply ultrasonic energy to fluid within the injection nozzle. The pressure application is configured to propel the fluid towards and out of the number of openings.

  • METHODS FOR EXPERIMENTAL EVOLUTION OF NATURAL AND SYNTHETIC MICROBES
    Publication number: 20210214713
    Abstract: Disclosed herein are a high-throughput continuous culture system and novel methodologies for the experimental evolution of natural and synthetic microbes using the continuous culture system. The microbial culture is exposed to a stress ramp function which is overlaid on top of a culture fitness function. The amount of stress applied to the culture is increased in response to increased fitness of the microbial culture.

  • Electrochemical processing of clathrate hydrates
    Patent number: 9234285
    Abstract: A method of using clathrate hydrates (including ammonia clathrates), in electrochemical transformations. Noted are converting clathrate guest molecules such as CO2, CH4, alkanes, and alkenes; and, optionally, the use of clathrates-promoting molecules such as tetra hydro furan, to produce higher value carbon molecules including propane and formic acid.
