US PATENTS: Controlled synthesis of nanoparticles using continuous liquid-flow aerosol method, etc.
Here are three US Patents dealing with nano-particles and aerosols. As you know the smaller the size of the particulates that we are inhaling as they inundate the air that we breathe, our every breath, the deeper they can go into the lungs and the more readily they can go into the blood stream. This means that whatever it is that is being delivered from the sky is now absorbed in our bodies and all life faster.
Even though these patents are said to pertain to medicines, food, cosmetics, coatings and other uses — the same technology can be used in geoengineering. All these technologies are plasma based. Everything we are being entrapped by is founded in plasma physics. The ordinary uses for plasma technologies that are evident in these three patents as examples are applicable to the global aerosol spraying that is occurring all over our planet every single day and is suffocating our every breath, bringing slow death to every living creature, Nature, the trees, whatever grows, including the food we eat and need to survive, and our only home planet Earth.
I asked a technically knowledgeable person, who has a lifetime of experience in these matters, if these patents – that are said to be used in medicines, chips, coatings, etc. according to the patents – are the same technologies used to generate the new wispy-fine toxic clouds that are everyday covering us in toxic nano-stuff. The reply was — YES! Definitely, the nano-particles are best suited because they can be put into jet fuel, and the jet engine combustion process doesn’t affect the particle, therefore they can use ANY jet aircraft to disperse. And the jet fuel is only a small part of the whole. The shear quantity of material raining down on us could not be introduced by fuel alone. It is “payload dispersion”. Payload dispersion is occurring.

Controlled synthesis of nanoparticles using continuous liquid-flow aerosol method
US 7811543 B2 / Oct. 12, 2010
A method and apparatus for producing surface stabilized nanometer-sized particles includes the steps of mixing reactants, a surface-stabilizing surfactant, and a high boiling point liquid to form a mixture, continuously passing the mixture through an ultrasonic spray nozzle to form a mist of droplets of the mixture, injecting the mist directly into a furnace to cause a reaction between species of the mixture, and collecting the nanometer-sized products. The ultrasonic nozzle is positioned directly at one end of the heating furnace, preferably the top end, for travel of the droplets through the furnace. The continuous liquid-flow process, along with certain operating parameters, eliminates the need for dilution of the high boiling point liquid with a low boiling point solvent as in the prior art, significantly increases the yield, improves the quality of the product, and makes the process scalable.
BACKGROUND OF THE INVENTION
The present invention relates to methods for controlled production of surface stabilized particles, such as semiconductor nanoparticles, nanooxides and nanometals (also called nanocrystals or quantum dots) and apparatus for such manufacture.
It is anticipated that the future will be the era of nanotechnology. Through nanotechnology, higher quality products can be made by using smaller amounts of materials to achieve the same desired effects. Customers will receive products at lower costs with greater functionality in smaller packages.
Particles with their smallest dimension between 1 to 100 nm have generated great scientific and commercial interest due to their size-dependent properties and potential uses in electronics, fluorescent imaging, medicine, the chemical industry and everyday life.
Process for production of nanoparticles and microparticles by spray freezing into liquid
US 6862890 B2 / March 8, 2005
The present invention provides a system and a method for the production of microparticles and nanoparticles of materials that can be dissolved. The system and method of the present invention provide quicker freezing times, which in turn produces a more uniform distribution of particle sizes, smaller particles, particles with increased porosity and a more intimate mixing of the particle components. The system and method of the present invention also produce particles with greater surface area than conventional methods. One form of the present invention provides a method for the preparation of particles. An effective ingredient is mixed with water, one or more solvents, or a combination thereof, and the resulting mixture is sprayed through an insulating nozzle located at or below the level of a cryogenic liquid. The spray generates frozen particles.
BACKGROUND OF THE INVENTION
Small particle engineering enables an active pharmaceutical ingredient (API) to be incorporated into a formulation for targeted drug delivery. Powder micronization can also be used to increase the dissolution rates of poorly water-soluble drugs.
Micronization procedures can modify particle size, porosity and density, and the API may be mixed with pharmaceutical excipients using small particle technologies to maximize delivery to the desired target for drug administration.
Particle formation technologies may be classified as either mechanical micronization processes or solution-based phase separation processes.
Method and a system for producing thermolabile nanoparticles with controlled properties and nanoparticles matrices made thereby
US 20130035279 A1 / Feb. 7, 2013
This disclosure relates to a method and a system of producing nanoparticles and nanoparticle matrices of thermolabile, biocompatible matrix materials, like lipids and biopolymers with controlled properties. A prototype pulse-heat aerosol system is described for single-step production of free, thermolabile nanoparticles with sufficient control over size, morphology and crystallinity with controlled-release properties, for possible therapeutic, cosmetic or diagnostic use. Nanoparticles of the range 50 to 500 nm are obtained and are found suitable for controlled drugs delivery.
The controlled-release of drugs, their targeting to specific sites in the human body and the protection of delicate bioactive agents is desirable for efficient drug delivery. One approach towards achieving these ends involves encapsulating bioactive agents in biocompatible nanoparticle matrices. Control is needed over particle size and size distribution, substructure, crystallinity and thickness of encapsulating shell.
1. A method for production of thermolabile nanoparticles of biocompatible matrix material(s) such as fatty acids, lipids and proteins optionally with active agents such as therapeutics, cosmetics and protein, comprising the steps of:
atomizing a solution of thermolabile, biocompatible matrix material(s) in aqueous or organic solvent(s), with or without said active agents(s), to create droplets
suspending said droplets in a carrier gas,
subjecting said carrier gas with droplets, suspended therein, through a pulse-heat aerosol reactor under predetermined heat pulse of controlled magnitude and duration,
quenching with cooling gas, and
collecting the nanoparticles produced.
An object of this disclosure is to produce thermolabile nanoparticles with sufficient control over size, morphology, crystallinity and controlled-release properties.
Another object of this disclosure is to produce such particles in a single step, continuous process through pulse-heat aerosol process by the application of a heat pulse of predetermined temperature and duration followed by thermal quenching.
Nanoparticles matrices of this disclosure are prepared by pulse-heat aerosol reactor method, which involves atomizing a liquid precursor solution containing thermolabile compounds (e.g. encapsulating matrix agents like lipids and/or biodegradable polymers and bioactive agents like drugs, proteins, peptides, nucleic acids, or combination thereof) into a carrier gas, subjecting the aerosol to a heat pulse of controlled magnitude and duration, followed by quenching with cold gas, and collecting the nanoparticles produced. The evaporation rate control thus achieved is used to obtain nanoparticle matrices with varying size, morphology and crystallinity, which have controlled-release properties. The devices consist of atomizer, pump, modular aerosol reactor enabling pulse-heating and means for quenching and temperature sensor.
