Abstract:
A microreactor assembly comprising a fluidic interconnect backbone and plurality of fluidic microstructures is provided. The fluidic microstructures are supported by respective portions of the fluidic interconnect backbone, The microreactor assembly comprises a plurality of non-polymeric interconnect seals associated with the interconnect input and output ports. The interconnect input port of the fluidic interconnect backbone is interfaced with the microchannel output port of a first fluidic microstructure at one of the non-polymeric interconnect seals. The interconnect output port of the fluidic interconnect backbone is interfaced with the microchannel input port of a second fluidic microstructure at another of the non-polymeric interconnect seals. The interconnect microchannel is defined entirely by the fluidic interconnect backbone and is configured such that it extends from the non-polymeric interconnect seal at the microchannel output port of the first fluidic microstructure to the non-polymeric interconnect seal at the microchannel input port of the second fluidic microstructure without interruption by additional sealed interfaces.

Abstract:
A microreactor assembly (100) is provided comprising a fluidic microstructure (10) and an injector assembly (20). The injector assembly (20) comprises a liquid inlet (22), a gas inlet (24), a liquid outlet (26), a gas outlet (28), a liquid flow portion (30) extending from the liquid inlet (22) to the liquid outlet (26), and a gas flow portion (40) extending from the gas inlet (24) to the gas outlet (28). Further, the injector assembly (20) defines an injection interface with a microchannel input port (14) of the fluidic microstructure (10). The injector assembly (20) is configured such that the gas outlet (28) of the gas flow portion (40) is positioned to inject gas into the liquid flow portion (30) upstream of the liquid outlet (26), into the liquid flow portion (30) at the liquid outlet (26), or into an extension (35) of the liquid flow portion (30) downstream of the liquid outlet (26). Further, the injector assembly (20) is configured such that gas is injected into the liquid flow portion (30) or the extension thereof as a series of gas bubbles. The resulting microreactor assembly (100), and the injector assemblies utilized therein, which can be used with a variety of microreactor designs, effectively improves the interfacial surface area within the microstructure without requiring excessive reduction of microchannel dimensions.
Abstract:
A reformable area and a non-reformable area of a sheet of glass material are heated to a first temperature corresponding to a first viscosity. The reformable area is subsequently locally heated to a second temperature corresponding to a second viscosity, where the second viscosity is lower than the first viscosity. A bend is formed in the reformable area during the local heating of the reformable area by contacting a first pusher with the non-reformable area and translating the first pusher along a linear path to apply a pushing force to the non-reformable area that results in the bend in the reformable area or by contacting a second pusher with an edge area of the reformable area and rotating the pusher along a circular path to apply a pushing force to the edge area of the reformable area that results in the bend in the reformable area.

A method for bending a sheet of material into a shaped article includes providing the sheet of material. A reformable area and a non-reformable area of the sheet of material are heated to a first temperature range corresponding to a first viscosity range. The reformable area of the sheet of material is subsequently heated to a second temperature range corresponding to a second viscosity range. The reformable area of the sheet of material is reformed into a selected shape by at least one of sagging the reformable area of the sheet of material and applying a force to the sheet of material outside of or near a boundary of the reformable area.
