Abstract:
The disclosure relates to methods and apparatuses for forming activated carbon from feedstock particles comprising a carbon feedstock and at least one activating agent. The feedstock particles are contacted with a plasma plume generated by the combination of RF and DC power sources. The feedstock particles may flow in a cyclonic pattern in the plasma plume for increased residence time. The carbon feedstock may be a carbon precursor material or a carbonized material. The feedstock particles are contacted with the plasma plume at a temperature and for a time sufficient to carbonize and/or activate the feedstock particles.

Abstract:
The disclosure relates, in various embodiments, to methods for forming activated carbon comprising (a) providing a feedstock mixture comprising a carbon feedstock, at least one activating agent chosen from alkali metal hydroxides, and at least one additive chosen from fats, oils, fatty acids, fatty acid esters, and polyhydroxylated compounds to form a feedstock mixture; (b) optionally heating the feedstock mixture to a first temperature, and when a step of heating the feedstock mixture to a first temperature is performed, optionally holding the feedstock mixture at the first temperature for a time sufficient to react the at least one activating agent with the at least one additive; (c) optionally milling and/or grinding the feedstock mixture; (d) heating the feedstock mixture to an activation temperature; and (e) holding the feedstock mixture at the activation temperature for a time sufficient to form activated carbon.
Abstract:
The disclosure relates to methods for forming activated carbon. In an example method, a feedstock mixture comprising carbon feedstock and at least one chemical activating agent is heated to at least a fluxing temperature to form a feedstock melt. The feedstock melt is atomized and introduced into a reactor and rapidly heated to at least a solidification temperature by introducing a hot stream into the reactor. The heated feedstock mixture is introduced into a reaction vessel, and held at a temperature and for a time sufficient to react the carbon feedstock with the at least one chemical activating agent to form activated carbon, wherein heating the atomized feedstock comprises heating the mixture within a time period sufficient to maintain the feedstock mixture in a substantially solid state throughout the rapid heating stage.
Abstract:
According to some embodiments method for making an optical fiber preform comprises the steps of: (i) placing a plurality of rods (115B) with an outer surface having a coefficient of friction 0.02
Abstract:
A electrostatic chucking apparatus and method for coating mobile device 2D or 3D cover glass in a vacuum coating chamber having a rotating drum and which is driven in rotation. The apparatus includes a carrier including a liquid-cooled cold plate which is removably mountable to the rotating drum. In the case of 3D cover glass, the carrier includes a portion with a 3D profile to match a 3D profile of the 3D cover glass. The carrier further includes an electrostatic chuck (ESC) adapted to secure the cover glass in place against the carrier in the face of centrifugal forces caused by rotation of the rotating drum, with the ESC developing a sufficient clamping force for reliably securing the cover glass in place.
Abstract:
A method of forming an optical fiber includes the steps of forming a silica-based soot blank with at least one silica-based soot core cane at least partially embedded in the soot blank. The soot blank with the soot core cane positioned therein is consolidated to form a preform. The preform is then drawn to form an optical fiber. The soot core cane preferably has an average bulk density within 10% of the bulk density of the soot blank, and more preferably within 5% of the bulk density of the soot blank.
