Provided is a storage device including a storage body for holding a liquid, a gas or an item, which has a first wall, a second wall, and a magnetic closure device for closing the storage body, which has a first closure part and a second closure part. The first closure part has a first strip body elongate along a transverse direction and is arranged on a first closing portion of the first wall. The second closure part has a second strip body elongate along a transverse direction and is arranged on a second closing portion of the second wall. The first closure part and the second closure part cooperate in a magnetically attracting manner. At least one of the first wall, the second wall, the first strip body and the second strip body are wholly or partly fabricated from a composition containing an antimicrobially active additive.

A method of lamellar corneal graft implantation is disclosed herein. In one or more embodiments, the method includes the steps of: (i) modifying a genetic component of a lamellar cornea or other tissue of an animal so that the lamellar cornea or other tissue of the animal can be used for human transplantation; (ii) decellularizing the lamellar cornea or other tissue ex vivo using chemical means; (iii) modifying a shape of the lamellar cornea or other tissue before or after transplantation; and (iv) applying a photosensitizer and ultraviolet radiation to the lamellar cornea or other tissue so as to crosslink collagen and intercellular proteins of the lamellar cornea or other tissue, kill the cells exposed to the photosensitizer, and eliminate an immune response by a host to the implanted lamellar cornea or the tissue.

The systems and methods disclosed herein are directed to an autonomous vehicle food locker system that may include environmentally controlled storage compartments for storing and/or transporting perishable food items to be delivered to end consumers. The storage compartments may provide ultraviolet light controls and surfaces that provide sanitized food storage areas for a delivery vehicle. Computing processor(s) may be configured for determining a sanitization procedure for sanitizing the interior portion of the food storage locker based on sensor information received from internal and external sensors, video feeds, photographs, and other information. The processor(s) may determine one or more sanitation characteristics that can indicate or inform cleanliness of the interior portion of the food storage locker, and perform automated sanitization procedures that can include activating a chemical layer disposed on the interior portion of the food storage locker. The system may also maintain a digital record documenting the delivery process.

A silicate-based lanthanide ion doped material converts electromagnetic radiation energy of a longer wavelength of below 530 nm to electromagnetic radiation energy of shorter wavelengths in the range of 220 to 425 nm. The silicate-based material is a crystalline silicate material doped with lanthanide ions selected from praseodymium, gadolinium, erbium, and neodymium. For co-doping, at least two of the lanthanide ions are used. The silicate-based material is obtainable from a blend comprising salts and an organic solvent, followed by specific calcination processes and tribological impacts to adjust particle size and to increase the crystallinity of the particles. The silicate-based material can be used to inactivate microorganisms or cells covering a surface containing the silicate-based material under exposure of electromagnetic radiation energy of a longer wavelength of below 500 nm.

A garnet is doped with a lanthanide ion selected from praseodymium, gadolinium, erbium, and neodymium. For co-doping, at least two of the lanthanide ions are selected. The lanthanide ion doped garnet converts electromagnetic radiation energy of a longer wavelength of below 530 nm to electromagnetic radiation energy of shorter wavelengths in the range of 220 to 425 nm. The garnet is crystalline and is obtainable from a mixture of salts or oxides of the components, in the presence of a chelating agent, that are dissolved in acid. This is followed by a specific calcination process to produce the garnet and, optionally, to adjust particle size and increase the crystallinity of the particles. The garnet can be used to inactivate microorganisms or cells covering a surface containing silicate-based material under exposure of electromagnetic radiation energy of a longer wavelength of below 500 nm.

The invention refers to an endoscope including at least one channel which may be contaminated in use, wherein the channel wall of the at least one channel is formed of a material having properties capable of photocatalysis. The invention further refers to a method for cleaning such an endoscope including the steps of: connecting the endoscope to a reprocessing device, performing a photocatalytic treatment at least in the at least one channel for the purpose of the decomposition of organic residues on the surface of the channel, and rinsing the endoscope. The invention further refers to a cleaning device for cleaning such an endoscope.

A LED ultraviolet germicidal lamp includes a bracket, a power box, a driving light source, a heat sink, an ultraviolet light source, a lampshade, a quartz glass, a catalyst gauze, and a lamp frame. The bracket is connected to the heat sink, and the power box and the driving light source are provided in the bracket in sequence from outside to inside. The driving light source is provided in the power box and is connected to the power box by bolts. The heat sink is connected to the power box and is provided at a lower end of the power box. Titanium dioxide is used as the catalyst and is catalyzed by the UVC light source. Hydroxyl radicals produced when nanoscale titanium dioxide catalyst gauze is exposed to the UVC light source destroy bacteria and viruses.
