Abstract: Ammonia is made in a system that includes a conversion reactor for performing a Haber-Bosch process. Effluent streams from the conversion reactor, which include an ammonia component and excess hydrogen and nitrogen reactants, are fed to a membrane separator that includes NaA zeolite membranes disposed on one or more hollow porous supports. The NaA zeolite membranes are highly selective for the ammonia component, allowing the ammonia to be collected from a lumen of the membranes as a product and enriching the excess hydrogen and nitrogen reactants for reuse in the conversion reactor. These systems and the methods of their use are effective to replace and/or modify the energy-intensive condensation/recycling steps in the traditional Haber-Bosch process used to condense NH3 from the exiting stream of the reactor. The selective removal of ammonia by high quality NaA membranes helps to shift the ammonia evolution reaction.

Abstract: Provided is a method for analyzing the stability of a PMSG-WT connected to a weak power grid considering the influence of power control. New energy power generation mostly uses a perturbation and observation (P&O) method for maximum power point tracking, and nonlinear discontinuous links therein make stability analysis difficult. The present application analyzes the stability of the PMSG-WT connected to the weak grid system based on a describing function method, and fully considers the nonlinear discontinuous links in the power loop, thus making the analysis result more accurate. At the same time, the describing function method is a method that can quantitatively calculate the frequency and amplitude of oscillation. The analysis method of the present application can provide a powerful and good reference for oscillation suppression and controller design.

Abstract: A minimally invasive penetrating microelectrode array is used to generate localized electric field “hotspots” for delivering biomolecules, such as nucleic acid or protein molecules, into cells located in the epidermal or dermal layer of the skin via transient membrane permeabilization. The “hotspots” can be controlled by selectively insulating the penetrating microelectrodes at specific regions. The portion of microelectrodes that are not covered with insulation coating can be coated with nucleic acid or protein vaccine vector, or other biomolecules to be delivered. Upon insertion into the skin, an anchor microelectrode region mechanically anchors the penetrating microelectrode to position the target tissue microelectrode region, so as to selectively align the biomolecule coating with cells located in the tissue location. The biomolecule coating will dissolve when in contact with surrounding tissue. By applying an electrical pulse, the biomolecules can be delivered into surrounding cells.
