Disclosed is a method for treating fly ash containing an initial carbon concentration to obtain ash containing a predetermined final carbon concentration less than the initial concentration, the method including: a step of granulometric separation of the ash into at least two fractions, a coarse traction and a fine fraction, the coarse fraction having a granulometry greater than the fine fraction; a step of extracting carbon from the ash; a method wherein the extraction step is subsequent to the separation step, the extraction step being implemented solely on the coarse fraction, by electrostatic separation, the method including a step of drying the ash during which the temperature of the ash is above 60 C.

A microparticle sorting apparatus includes a detection unit which detects microparticles flowing through a flow path; an imaging device which images a droplet containing the microparticles which is discharged from an orifice provided on an edge portion of the flow path; a charge unit which applies a charge to the droplets; and a control unit which determines a delay time as from a time that the microparticles are detected by the detection unit to the time at which a number of bright spots in a standard region, which is set beforehand, of image information imaged by the imaging device reaches the maximum, making it possible for the charge unit to apply a charge to the microparticles once the delay time has lapsed after the microparticles are detected by the detection unit.

Microsphere compositions containing a mixture of at least two materials with same or differing phases are described. The materials have differing optical dispersion curves that intersect at at least one particular wavelength exhibiting the Christiansen effect. The materials may be encompassed by a microsphere, which may also include a separation entity.

The present invention comprises a method of shredding treated medical waste, cleaning it of all traces of biological gunk, and sorting it into separate components for recycling. To clean biological gunk from materials, all materials must be first shredded into small parts to expose the interior. The cleaning is performed by submerging the gunk coated materials into a caustic solution that breaks down and dissolves the gunk off of the materials. The caustic solution may comprise sodium hydroxide, potassium hydroxide, or a similar chemical, which is highly effective in producing a corrosive chemical that can break down blood, bone marrow, urine, unused medication, food waste, organs, tissues and any other biologic materials. After all of the biological material is removed from the cleaned materials, they are sorted into component materials, such as plastics, metals, rubbers, glass, etc.

The present invention provides a method for aligning nanowires which can be used to fabricate devices comprising nanowires that has well-defined and controlled orientation independently on what substrate they are arranged on. The method comprises the steps of providing nanowires and applying an electrical field over the population of nanowires, whereby an electrical dipole moment of the nanowires makes them align along the electrical field. Preferably the nanowires are dispersed in a fluid during the steps of providing and aligning. When aligned, the nanowires can be fixated, preferably be deposition on a substrate. The electrical field can be utilized in the deposition. Pn-junctions or any net charge introduced in the nanowires may assist in the aligning and deposition process. The method is suitable for continuous processing, e.g. in a roll-to-roll process, on practically any substrate materials and not limited to substrates suitable for particle assisted growth.

A method and system for air classification of a milled feed stock includes generating a feed stream by combining the milled feed stock with at least one gasflow element, wherein the milled feed stock includes a plurality of particle sizes. The method and system includes directing the feed stream across a curvilinear surface, such that the milled feed stock in the feed stream separates into a plurality of classification streams, each of the plurality of classification streams based on the particle sizes of the milled feed stock. Therein, the method and system separates the plurality of classification streams and collects each of the plurality of classification streams, thereby classifying the milled feed stock contained therein based on the particle sizes for each of the plurality of classification streams.
