Burners and methods of making burner bodies via a focused beam are disclosed. In an aspect, a burner includes (a) a burner body and (b) at least one connector configured to supply at least a fuel and an oxidizer to the burner body. The burner body includes (1) a plurality of passageways; (2) a first major surface; (3) a plurality of ports at the first major surface, each port defined by an end of one of the passageways; and either: (4a) at least one heating element in or adjacent to at least one of the plurality of passageways that increases the temperature of a wall of the at least one of the plurality of passageways; or (4b) a cooling chamber directly adjacent to three or more of the plurality of passageways. The burner body includes a number of layers of metal directly bonded to each other. Further, methods are provided, including receiving, by a manufacturing device having one or more processors, a digital object comprising data specifying a burner body; and generating, with the manufacturing device by an additive manufacturing process, the burner body based on the digital object. A system is also provided, including a display that displays a 3D model of a burner body; and one or more processors that, in response to the 3D model selected by a user, cause a 3D printer to create a physical object of the burner body.

Burners and additive manufacturing methods

Compositions are provided that include a matrix and a polymeric composite particles disposed in the matrix. The polymeric composite particles include a porous polymeric core and a fragrance positioned within the porous polymeric core. Polymeric composite particles are also provided including a porous polymeric core, a fragrance positioned within the porous polymeric core, and a coating layer around the porous polymeric core. Further, a method of determining a minimum temperature of a composition is provided including providing a composition including polymeric composite particles disposed in a matrix, heating the composition, releasing at least a portion of the fragrance as a vapor from the porous polymeric core of the polymeric composite particles at or above the minimum temperature, and detecting at least a portion of the fragrance vapor in a location outside of the matrix.

Polymeric composite particles

A catalyst-containing particle including a core and an acidic coating layer thereon, wherein the core includes a nitrogen-containing catalyst for a thermoset polymeric system, and the acidic coating layer comprises a binder; and a method of making such particles. A curable, one-part epoxy/thiol resin composition that includes: an epoxy/thiol resin mixture including: an epoxy resin component that includes an epoxy resin having at least two epoxide groups per molecule; a thiol component that includes a polythiol compound having at least two primary thiol groups; and catalyst-containing particles dispersed in the epoxy/thiol resin mixture; wherein each particle includes a core and an acidic coating layer thereon, wherein the core includes a nitrogen-containing catalyst for the epoxy resin; and a method of curing such curable composition.

Epoxy stabilization using acid-coated nitrogen containing catalysts, particles, and methods

Composite particles are provided that can be used to cure epoxy resins. More particularly, the composite particles have a porous polymeric core particle, a curing agent and/or a curing catalyst for an epoxy resin positioned within the porous polymeric core particle, and a fluoropolymer-containing coating layer around the porous polymeric core particle. Additionally, curable compositions are provided that are mixtures containing an epoxy resin and the composite particles. The epoxy resin typically does not react until the curable composition is heated causing the release of the curing agent and/or curing catalyst from the composite particle. Further, cured compositions formed from the curable composition are provided.

Composite particles for curing epoxy resin compositions and curable and cured epoxy resin compositions prepared using the particles

Polymeric composite particles are provided that can be used for the storage and delivery of various biologically active agent. The polymeric composite particles contain a porous polymeric core and a coating layer around the porous polymeric core. The porous polymeric composite particles typically further include a biologically active agent positioned within the porous polymeric core but not covalently bonded to the porous polymeric core. The biologically active agent can be released from the polymeric composite particle by diffusing out of the porous polymeric core through the coating layer.
