  • Publication number: 20230175886
    Abstract: An apparatus is configured to count N-photon events within a time-dependent sequence of events of interactions of a plurality of photons with a light sensitive detector. The apparatus includes a signal-processing device and the light sensitive detector. An N-photon event represents an occurrence of at least N timely overlapping single photon events. The light sensitive detector is adapted to generate a time-dependent digital signal comprising digital patterns representing the time-dependent sequence of events from the detection of the plurality of photons with the light sensitive detector. Each digital pattern in the digital signal comprises a digital pattern width having a continuous sequence of digital values representing at least one event of interaction of at least one photon with the light sensitive detector. The signal-processing device is adapted to identify N-photon events from the digital patterns in the digital signal in dependence from the respective digital pattern width.

  • Publication number: 20230002284
    Abstract: A glass/quartz composite structure comprises quartz grit (and/or nan-glass crystals), quartz powder and glass grit wherein the glass grit is in an amount greater than any other single material by weight of the composite structure (e.g. a combined weight of the quartz grit, quartz powder, glass grit, resin, and coupling agent). Natural stone components, which may include the quartz grit and quartz powder, may be in an amount greater than 30% by weight of the composite structure. The structure may be formed into a 1.2-1.5 cm thick slab for countertops using standard cabinet perimeter support. The slab may be made by mixing the quartz grit, quartz powder, glass grit, and binding resin, pouring the mixture in a mold, and compacting the mixture in the mold. Specific natural mineral components, decorative chips, and/or wet mixture pieces may be added to the composite structure to provide aesthetics of specific natural stones.

  • Publication number: 20220395610
    Abstract: A bone regeneration material has a cotton-wool like structure formed of a plurality of electrospun fibers that contain bound BMP-2 through ?-TCP binding peptide. The electrospun biodegradable fiber contains 25-65 vol % of ?-TCP particles distributed in the fiber such that a portion of the ?-TCP particles is exposed on a surface of the electrospun fiber and the remaining portion of the ?-TCP particles is buried in the fiber. ?-TCP binding peptides that are fused with BMP-2 are bound to the ?-TCP particles so that BMP-2 is tethered to ?-TCP particles on the surface of the fibers. Upon implantation of the bone regeneration material in a bone defect site of a human body, BMP-2 that are tethered to ?-TCP particles on the surface of the bone regeneration material promotes proliferation and differentiation of cells at the bone defect site.

  • Publication number: 20220389374
    Abstract: Embodiments of this disclosure relate to bioinks and bioink compositions. These bioinks may be 3D printed into a hydrogel. The printed hydrogel may support primary cell and induced pluripotent stem cell attachment, proliferation, and spreading. Compounds in the bioink may be modified to incorporate chemical functionality, such as by chemical synthesis means. Incorporating chemical functionality may allow the incorporation of modified material as a component in the bioink. The modifications may allow chemical conjugation of a desired component. The desired component may maintain its cell interactive feature to aid in cell attachment and proliferation. Such incorporation may allow modulation of the bioprinted object's mechanical properties without interfering with cell adhesion.

  • Publication number: 20220356433
    Abstract: The systems and methods of the present disclosure can be used to generate systems and models that are physiologically relevant to the human and animal system. These physiological conditions can be designed to mimic the actual human condition for cell differentiation and proliferation. The system and methods of this present disclosure allow the formation of an appropriate biomaterial to mimic that which exists in a human or animal scaffold. Utilizing 3D printing technology, a hydrogel scaffold can be printed at various resolution very close to human physiological geometry. Additionally, the architecture can be optimized for the selected application and appropriate cells can be seeded on the scaffold prior to testing.
