  • Publication number: 20210324391
    Abstract: A recombinant microorganism, a preparation method thereof and its application in the production of coenzyme Q10. Specifically, the present disclosure provides a method of exogenously introducing a gene encoding the global regulatory protein irrE to construct a recombinant microorganism. This recombinant microorganism is suitable for producing coenzyme Q10 by fermentation method, and is particularly suitable for producing oxidized coenzyme Q10. The recombinant microorganism of the present disclosure has stress resistance, and has good tolerance against harsh environments including high osmotic pressure and high redox potential, thus making it possible to significantly increase the yield of coenzyme Q10, especially the yield of oxidized coenzyme Q10.

  • Patent number: 11104620
    Abstract: A method for manufacturing nano-sized insensitive high explosive molding powder usable as a booster HE is provided herein. The method preferably involving the steps of dissolving a binder in a liquid and suspending crystalline high explosive to said liquid, grinding that suspension in a bead mill until the crystalline high explosive is nano-sized, and precipitating the binder and crystalline high explosive using a spray dryer to produce granules containing nano-sized crystalline high explosive. The liquid may be water or an organic solvent so long as the binder is highly soluble in the liquid and the crystalline high explosive is generally insoluble in the liquid. A fatty alcohol, water defoaming/dispersant/surfactant agent can be added to the dissolved binder/suspended crystalline high explosive, to aid in the manufacturability.

  • Patent number: 9790137
    Abstract: A method of manufacturing a CL-20/HMX cocrystalline explosive which is coated in a polymeric binder, so as to be useful as an explosive molding powder. The cocrystalline material having a desirable average crystal size of from about 300 nm to about 1000 nm, which crystals are intimately coated with a polymeric binder and are produced as granular agglomerates that are less than on average 5 microns in size, and which crystals are relatively easy and safe to handle, transport, store and use. The method involving spray drying a CL-20 and HMX solvent solution containing a polymeric binder to form an intermediary amorphous material—which intermediary is then heated to cocrystallize the CL-20/HMX into the desired size cocrystals and aggregates thereof—which are coated in said polymeric binder.

  • Patent number: 9399580
    Abstract: Granules of graphene oxide may be produced from a dispersion of nanoscale graphene oxide sheets by a spray drying method. Such granules have a three-dimensional corrugated morphology. The complexity of the corrugations, and the size distribution of the granules can be varied through selection of the spray-drying equipment used, and variation of the composition of the dispersion and the spray-drying parameters. Structural modifiers may be included in the graphene oxide dispersion to control the ultimate morphology of the granules. The granules of graphene oxide may be thermally reduced at a moderate temperature of 220° C. to increase the granules' electrical conductivity. The reduced granules may be used to fabricate electrodes for supercapacitors. The power and energy density of such an electrode material is comparable to those of conventional/commercial activated carbon-based electrodes.

  • Patent number: 9212102
    Abstract: An insensitive crystalline high explosive molding powder, usable as a booster HE. The subject insensitive crystalline high explosive molding powder being manufactured by adding the crystalline high explosive, metal or semi-metal particles and a polymer or wax based binder to a solvent to form a solution, spray drying the solution to drive off the solvent, thereby co-precipitating the HE and binder to form granules in which the crystals of HE and metal particles are uniformly distributed in the binder.
