The present invention provides additive manufacturing compositions, also referred as “inks” in the field of additive manufacturing, which can be fine-tuned with respect to porosity by varying the intensity of the photopolymerisation light source and which can further be used to obtain objects out of glasses, ceramics or glass-ceramics and their respective alloys.

A method of capturing soot includes the steps: combusting a first precursor in a burner to produce a soot stream, the soot stream comprising soot and exiting the burner at an outlet; and directing a capture medium to the soot stream, the capture medium contacting the soot in an impact region, the soot having a temperature greater than 50° C. in the impact region.

A method for producing a solid electrolyte, including: stirring a slurry including lithium sulfide and phosphorus sulfide in a hydrocarbon solvent in a reaction vessel, and circulating the slurry through a connecting pipe by a pump. The method is carried out in an apparatus including the reaction vessel and the connecting pipe connected to the pump and the reaction vessel.

Annealing treatments for modified titania-silica glasses and the glasses produced by the annealing treatments. The annealing treatments include an isothermal hold that facilitates equalization of non-uniformities in fictive temperature caused by non-uniformities in modifier concentration in the glasses. The annealing treatments may also include heating the glass to a higher temperature following the isothermal hold and holding the glass at that temperature for several hours. Glasses produced by the annealing treatments exhibit high spatial uniformity of CTE, CTE slope, and fictive temperature, including in the presence of a spatially non-uniform concentration of modifier.

The invention discloses porous, bioactive glass and glass ceramic morsels or pellets to be used as tissue graft substitute materials and processes for obtaining the same wherein the bioactive glass and glass ceramic morsels or pellets are made up of natural agents like phosphate, calcium, sodium and other elements which are not alien to the human or animal body. The said preparation process encompasses various steps like quenching sintering, foaming, and sol-gel casting which render the glass morsels or pellets unique bioactivity and enhanced porosity which may facilitate tissue repair and augmentation during tissue graft replacement.

An additive manufacturing ink composition may include a fluid medium. The ink may further include a chalcogenide glass suspended within the fluid medium to form a chalcogenide glass mixture. The ink may also include a surfactant. A method for forming an additive manufacturing ink may include wet milling a chalcogenide glass in a fluid medium and a surfactant to produce a chalcogenide glass mixture. The method may also include, after wet milling the chalcogenide glass, processing the chalcogenide glass mixture to reduce an average particle size of the chalcogenide glass.

A device formation method may include printing a chalcogenide glass ink onto a surface to form a chalcogenide glass layer, where the chalcogenide glass ink comprises chalcogenide glass and a fluid medium. The method may further include sintering the chalcogenide glass layer at a first temperature for a first duration. The method may also include annealing the chalcogenide glass layer at a second temperature for a second duration. A device may include a substrate and a printed chalcogenide glass layer on the substrate, where the printed chalcogenide glass layer includes annealed chalcogenide glass, and where the printed chalcogenide glass layer is free from cracks.
