Abstract: Devices and methods of providing a high-performance optical sensor disclose a sensor comprised of a porous material designed to have a multilayer rib-type or multilayer pillar-type waveguide geometry. The resulting porous nanomaterial multilayer-rib or multilayer-pillar waveguide design is optically capable of achieving ˜100% confinement factor while maintaining small mode area and single-mode character. Fabrication of the device is enabled by an inverse processing technique, wherein silicon wafers are first patterned and etched through well-established techniques, which allows porous nanomaterial synthesis (i.e., porous silicon anodization) either at the wafer-scale or at the chip-scale after wafer dicing. While ˜100% is an optimal target, typical devices per presently disclosed subject matter may operate with ˜98-99+%, while allowing for some design adjustments to be made if necessary, and still maintaining high sensitivity. i.e., >85-90% confinement suitable in some applications. In those instances, a primary benefit would still be use of the presently disclosed fabrication technology.

Abstract: A fiber includes a core and cladding, both of which may have temperature dependent indices of refraction. The materials and size of the core and cladding may be selected such that as the temperature of the core and/or cladding is heated above room temperature, the fiber transitions from supporting multimode optical waveguiding to supporting single mode waveguiding.

Abstract: Photocatalytic water treatment methods that can be particularly beneficial in degradation of PFAS and reactors and reactor systems that can be useful in carrying out the PFAS degradation protocols are described. Methods utilize bismuth phosphate-based semiconductors as catalysts in particulate or other effective high-surface area water-contacting form. The catalysts can be excited by UV light to induce reduction reactions that degrade or transform PFAS contaminants in the water. Reactor systems include multiple reactors in series and/or parallel. Each reactor includes mixers to encourage turbulent flow within the reactor, control of which is isolated from residence time control within the reactor. The reactors include a light source to deliver about 200 W/L or less of activating radiation emission to the internal volume of the reactor, providing a highly efficient photocatalytic reaction system.

Abstract: A hydrogen permeation membrane is provided that can include a carbon-based material (C) and a ceramic material (BZCYT) mixed together. The carbon-based material can include graphene, graphite, carbon nanotubes, or a combination thereof. The ceramic material can have the formula BaZr1-x-y-zCexYyTzO3-δ, where 0≤x≤0.5, 0≤y≤0.5, 0≤z≤0.5, (x+y+z)>0; 0≤δ≤0.5, and T is Yb, Sc, Ti, Nb, Ta, Mo, Mn, Fe, Co, Ni, Cu, Zn, Ga, In, or a combination thereof. In addition, the BZYCT can be present in the C-BZCYT mixture in an amount ranging from about 40% by volume to about 80% by volume. Further, a method of forming such a membrane is also provided. A method is also provided for extracting hydrogen from a feed stream.

Abstract: This system is directed to a computerized system for development of textiles with modified physical properties through stitching and can include a set of non-transitory computer readable instructions configured for: receiving a design pattern representing desired physical properties of a textile having a higher stiffness area and a lower stiffness area; developing a contiguous stitching pattern constrained by a pattern perimeter boundary and having a continuous stitching path, developing a first stiffness area within the contiguous stitching pattern having a first area of density, developing a second stiffness area within the contiguous stitching pattern having a second area of density wherein the first area of density has more stitch density than the second area of density, and transmitting the contiguous stitching pattern to an embroidery machine configured to provide a textile having the contiguous stitching pattern incorporating into the textile.

Abstract: Contaminant treatment methods and systems are described. Methods utilize biodegradable, non-toxic materials that can carry one or more functionalities useful for the remediation of fluids such as liquid or gaseous waste streams, chemical spills, etc. The carrier materials carry one or more functional groups that can target particular contaminants of a fluid for removal and/or modification to a more benign form. Targeted contaminants can include components of gaseous and/or liquids such as, and without limitation, gaseous discharges including VOCs and potentially hazardous contaminants such as organophosphorous compounds.

Abstract: Biocompatible biomimetic materials that exhibit desirable mechanical properties while also encouraging cell ingrowth and proliferation are described. The biomaterials include a multi-layer laminate of three or more decellularized aligned collagen tissues. The individual layers are aligned with one another in an angle-ply arrangement, with the collagen of each layer aligned at an angle to the collagen of the adjacent layer. The biomaterials are useful as collagenous graft materials such as a patch for a hernia in an annulus fibrosus or grafting materials for repair of tendons, ligaments, cartilage and other musculoskeletal tissues.
