Abstract: A thermally treated metal sheet or article as well as processes and systems for making the thermally treated sheet or article is provided. The process comprises heating and/or cooling the metal sheet by non contact thermal conduction for sufficiently long to provide a desired microstructure and mechanical properties. The process results in thermally treated metal sheets.

Abstract: An optical fiber with low attenuation and methods of making same are disclosed. The optical fiber has a core, an inner cladding surround the core, and an outer cladding surrounding the inner cladding. The outer cladding is chlorine-doped such that the relative refractive index varies as a function of radius. The radially varying relative refractive index profile of the outer cladding reduces excess stress in the core and inner cladding, which helps lower fiber attenuation while also reducing macrobend and microbend loss. A process of fabricating the optical fiber includes doping an overclad soot layer of a soot preform with chlorine and then removing a portion of the chlorine dopant from an outermost region of the overclad soot layer. The soot preform with the modified chlorine dopant profile is then sintered to form a glass preform, which can then be used for drawing the optical fiber.

Abstract: Methods of selecting, from a set of like optical fibers, a subset of optical fibers that can meet both short-wavelength and target-wavelength bandwidth requirements are disclosed. The method includes obtaining short-wavelength bandwidth data from DMD measurements, and determining a peak wavelength for each optical fiber. A target-wavelength bandwidth is then calculated using the determined peak wavelengths. The calculated target bandwidth is then compared to the short-wavelength and target-wavelength bandwidth requirements to identify which of the optical fibers satisfy these requirements.

Abstract: A method to form a laminar integral skin of a honeycomb structure is provided. The method includes extruding a ceramic precursor batch through a die with feedholes in entry side and slots in exit face of the die to form the honeycomb structure. In a region on the periphery of the die configured to form the cell matrix, a series of concentric slots around the matrix in the exit face of the die are configured to feed skin onto the matrix. Ring sections between concentric slots are angled away from the center and a mask is disposed on top of the periphery producing a channel for extruded skin to meet and bond to extruded matrix. Optionally, slots in the skin-forming ring sections enhance knitting between laminar skin layers. The die and honeycomb body having uniform integral skin are also provided.

Abstract: A method of controllably bonding a thin sheet having a thin sheet bonding surface with a carrier having a carrier bonding surface, by depositing a carbonaceous surface modification layer onto at least one of the thin sheet bonding surface and the carrier bonding surface, incorporating polar groups with the surface modification layer, and then bonding the thin sheet bonding surface to the carrier bonding surface via the surface modification layer. The surface modification layer may include a bulk carbonaceous layer having a first polar group concentration and a surface layer having a second polar group concentration, wherein the second polar group concentration is higher than the first polar group concentration. The surface modification layer deposition and the treatment thereof may be performed by plasma polymerization techniques.

Abstract: According to embodiments, an optical fiber may include a core portion comprising a radius rC, a centerline CL, a numerical aperture NA greater than or equal to 0.15 and less than or equal to 0.25, a graded relative refractive index profile having a maximum relative refractive index ΔCmax and an α value greater than or equal to 1 and less than or equal to 3. The core portion may include an up-dopant with a graded concentration from the radius rC to the centerline CL and an attenuation dopant with a constant concentration from the centerline CL of the core portion to the radius rC of the core portion. The optical fiber is multi-moded for wavelengths of light within a range from 800 nm to 1350 nm and an attenuation of the optical fiber wavelengths between 800 nm and 1000 nm is greater than or equal to 0.5 dB/m.

Abstract: Optical preforms and methods for forming optical preforms are disclosed. According to one embodiment, a method for producing an optical preform includes compressing silica-based glass soot to form a porous optical preform comprising a soot compact. The porous optical preform is heated to a dwell temperature greater than or equal to 100° C. Thereafter, the porous optical preform is humidified at the dwell temperature in a water-containing atmosphere having a dew point greater than or equal to 30° C. to form a humidified porous optical preform. The soot compact portion of the humidified porous optical preform generally comprises greater than or equal to 0.5 wt. % water.
