Food locker sanitation system for autonomous vehicles

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.

Sterilization of self-assembling peptides by irradiation

Gamma ray and e-beam irradiation provided efficient sterilization of certain self-assembling peptides (including RADA16 in solution) without substantial degradation of the major peptide, while, e.g., another self-assembly peptide, QLEL12 was significantly degraded following irradiation. Irradiation sterilization enhances the rheological property of, for example, RADA16 hydrogel once applied to tissue at a physiological pH. The rheological property increase can result in higher efficacy in a variety of biomedical applications.

Blue to UV Up-Converter Comprising Lanthanide Ions such as Pr3+ Activated and optionally Gd3+ Co-Activated Silicates and its Application for Surface Disinfection Purposes

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.

Blue to UV Up-Converter Comprising Lanthanide Ions such as Pr3+ Activated Garnet and its Application for Surface Disinfection Purposes

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.
