Abstract:
An apparatus (1) for sampling and detecting a pathogen in air comprising a first air sampling module (A), a second module (B) for the isolation of viral RNA and a third module (C) for amplification and detection of the viral RNA; thanks to the integration between the modules (A, B, C) the apparatus (1) is compact and portable and can be used for in situ sampling of air in closed environments such as ambulances or hospital rooms, air in the external environment and air exhaled by patients.
Abstract:
A device (1) for the disinfection of a volume containing a gaseous fluid, comprising a hollow body (2) having a reflective inner surface (7), an inlet opening (3) and an outlet opening (4), and one or more sources (5) of ultraviolet UV-C radiation placed inside the body (2); the body (2) defines an optical cavity generating a multiplicative effect of the illumination intensity due to multiple reflections inside the body (2). The device can be used in assisted breathing or ventilation systems for disinfecting the air exhaled by a patient when connected to an interface device (14) such as a mask.
Abstract:
A device for disinfecting an air flow, comprising a hollow body (2) having an axis A, a side wall (3) and two base walls (4,5) provided with internal reflective surfaces, an inlet opening (6) and an outlet opening (8) formed in the respective base walls and at least one source (15) of UV-C radiation disposed within the hollow body (2), and a helical-shaped deflector (10) axially housed in the hollow body (2); wherein the hollow body (2) is cylindrical and an outer edge of the deflector (10) cooperates substantially sealingly with the inner surface (12) of the side wall (3) of the hollow body (2) so as to define with said side wall (3) a helical conduit (13) traversed by the entire flow. The device may be used in assisted ventilation systems to disinfect the air exhaled by a patient.
Abstract:
A process for manufacturing an optical element (1) comprising a first step of spinning a circular sheet (2) of a first metallic material for it to adhere to a rotating matrix (3) and form a shell (8); a second step of assembling the shell (8) on a temporary support (10); and at least a third step of diamond spinning the shell (8) by means of a diamond tool (13) to obtain an optical surface (14).
Abstract:
Device for disinfecting a fluid in a conduit (1) comprising an outer casing (3) adapted to be connected to at least a portion of said conduit (1) and having a longitudinal axis (A) and a source (6) of UV-C radiation housed in the casing (5), wherein the casing (5) includes at least one side wall (5) having a longitudinal section with a curved profile with the concavity facing the interior of the casing.
Abstract:
A method for applying a carbon-based reflective overcoating on a grazing incidence optical unit comprising a substrate and a coating of a high-density material chosen from the group comprising gold, platinum, iridium, palladium, rhodium, ruthenium, chrome and nickel or a low-density material such as carbon or B4C; the method comprises the step of treating the optical unit with a solution or gaseous phase containing at least one polymer precursor material to create the overcoating through absorption of the polymer material on the coating.
Abstract:
An apparatus for non-invasive inspection of solid bodies by muon imaging, comprising a receiver (3) adapted to intercept a muon flux associated with cosmic rays passing through a portion of a body to be inspected, sensor means (4) adapted to detect the amount of photons or Cherenkov radiation associated with the intercepted muon flux, electronic processing means adapted to reconstruct energy and direction of the muon flux incident the portion of the body to be inspected to calculate the local density thereof. The receiver (3) comprises an optical device (5) provided with at least one receiving surface (6) having reflecting and/or diffractive properties adapted to convey the Cherenkov radiation associated with muons toward the sensor means (4), these latter comprising a multipixel detection chamber (8) adapted to provide an annular image of the muon having radius and position variable as a function of the energy and direction of muon flux.
Abstract:
Method for manufacturing an optical unit (1) comprising a plurality of glass-sheets (2) having an aspherical shape, arranged superimposed and spaced apart to form a stack (10), comprising the steps of: - arranging either a pre-bent or a flat glass-sheet (2) on a reference surface (5) having the geometry desired to be reproduced; - cold-deforming said glass-sheet (2) so as to adhere it onto the reference surface (5); - integrating said glass-sheet (2) with a preceding element (4, 2) of said stack (10) in a predetermined relative position; and - repeating the preceding steps till stack completion. The integration step comprises fastening said glass-sheet (2) in a position spaced from the preceding element (4, 12) of the stack (10) by means of bars (3) arranged spaced apart from one another.
