  • Publication number: 20250051554
    Abstract: Closed cell chitin foam is provided. The closed-cell chitin foam composition does not absorb water, is biodegradable, and is mechanically characterized by a density range of 16 to 800 kg/m3, closed-cell pore sizes ranging from 50 microns to 1 mm, an elastic modulus of 3 to 175 MPa, and a tensile strength of 0.15 to 6.5 MPa. The chitin is at least 70% acetylated. In one aspect, the foam is enclosed in a shell e.g. in the form of a surfboard. Chitin foam according to this invention is fully biodegradable. The chitin foam overcomes the current problems with foams that contain polyurethane and polystyrene, and which are manufactured from petroleum-based sources. Petroleum based foams are not renewable, have an adverse impact on our environment, and pose significant health hazards to those who manufacture them. The chitin foam with its water-based manufacturing process and naturally sourced chitin, solves these problems.

  • Patent number: 11637271
    Abstract: A method of forming microelectronic systems on a flexible substrate includes depositing a plurality of layers on one side of the flexible substrate. Each of the plurality of layers is deposited from one of a plurality of sources. A vertical projection of a perimeter of each one of the plurality of sources does not intersect the flexible substrate. The flexible substrate is in motion during the depositing the plurality of layers via a roll to roll feed and retrieval system.

    Abstract: A composite material includes a polymer matrix with a polymer having D-glucosamine monomer units and 50% or fewer N-acetyl-D-glucosamine monomer units. A salt can be disposed in the polymer matrix. A dispersed phase is disposed in the polymer matrix with the salt, and the dispersed phase and the polymer matrix form a porous composite foam. The porous composite foam includes, by weight, 0.5-3 times the dispersed phase to the polymer matrix, and the porous composite foam has a density of less than 1 g/cm3.

  • Patent number: 8947653
    Abstract: A method for detecting a coating on a bottle includes directing light at a first point of incidence on the bottle and detecting a first intensity of reflected light from the first point of incidence on the bottle. Further, light is directed at a second point of incidence on the bottle and a second intensity of reflected light from the second point of incidence on the bottle is detected. The first intensity is compared to the second intensity to determine whether the coating on the bottle has been uniformly deposited.
