Abstract:
A method for the preparation of a highly polarized nuclear spins containing sample of an organic or inorganic material, containing H or OH groups or adsorbed water molecules. Such highly polarized nuclear spins containing samples can be subjected to nuclear magnetic resonance (NMR) measurement and/or can be thawed and immediately administered to an individual undergoing a magnetic resonance imaging (MRI) scan. The method is based on generating unstable radicals on the surface of the sample in the presence of ionized environment followed by cooling the sample to cryogenic temperatures. A device for carrying out a particular step of said method is also discloses.
Abstract:
Verfahren und Vorrichtungen zur Präparation mikroskopischer Proben mittels Lichtpulsen, wobei Volumen abgetragen werden, die größer als 100 µm 3 sind. Das Verfahren umfasst folgende Schritte: - Inspizieren eines Objekts mittels eines Rasterelektronenmikroskops (REM) oder eines fokussierten Ionenstrahls (FIB), wobei ein Bild des Objekts aufgenommen wird - Festlegen eines zu untersuchenden Bereichs des Objekts - Festlegen eines Laser-Bearbeitungsweges anhand des Bilds des Objekts derart, dass eine Probe aus dem Objekt herauspräpariert werden kann. - Entfernen eines abzutragenden Volumens durch Laserbearbeitung entlang des festgelegten Laser-Bearbeitungswegs - Inspizieren des Objekts mittels Rasterelektronenmikroskop (REM) oder fokussiertem Ionenstrahl (FIB).
Abstract:
An electron beam sterilization device includes: a sterilization chamber (6) in which electron beams are applied to containers to perform sterilization; a blocking cover member that covers the sterilization chamber (6) and blocks radiations; and a rotational member having an upper portion exposed through an opening portion (44) formed in the blocking cover member. The blocking cover member includes a fixed blocking cover (41) that covers the upper portion of the rotational member. Between the rotational member and the fixed blocking cover (41), there are provided a rotational annular blocking plate (64) that projects from the rotational member toward the fixed blocking cover (41) and a fixed annular blocking plate (65) that projects from the blocking cover member toward the rotational member. The rotational annular blocking plate (64) and the fixed annular blocking plate (65) face each other with a blocking gap (66) therebetween. The rotational annular blocking plate (64) and the fixed annular blocking plate (65) constitute a blocking lap portion (67) that blocks radiations.
Abstract:
An electron beam sterilization device (1) includes a rotational member (22) that rotates around vertical rotational shafts (33), (34), and the rotational member (22) includes an upper stage (25), a middle stage (27), and a lower stage (26). On the upper stage (25), there are provided a plurality of electron beam emission units (15) arranged along the circumferential direction. On the middle stage (27), there is provided a retaining device (17) that retains a container (2). On the lower stage (26), there are provided a plurality of power supply units (71) that supply power to the electron beam emission units (15). Power supply cables (72) extend from the power supply units (71) to the upper stage (25) along the rotational shafts (33), (34) and are connected to the electron beam emission units (15).
Abstract:
The present invention generally relates to a low temperature plasma probe for desorbing and ionizing at least one analyte in a sample material and methods of use thereof. In one embodiment, the invention generally relates to a low temperature plasma probe including: a housing having a discharge gas inlet port, a probe tip, two electrodes, and a dielectric barrier, in which the two electrodes are separated by the dielectric barrier, in which application of voltage from a power supply generates a low temperature plasma, and in which the low temperature plasma is propelled out of the discharge region by the electric field and/or the discharge gas flow.
Abstract:
The present application is directed to methods and devices for altering material properties of lubricants and other cross-linkable compounds comprising organic or organometallic materials through exposure to energized gaseous species. The energized gaseous species may create reactive sites among lubricant molecules that may alter their material properties by cross-linking at least a portion of the lubricant molecules. The cross-linked lubricant may reduce the ability of the lubricant to migrate away when force is applied between lubricated sliding friction surfaces.
Abstract:
Lithographic apparatuses suitable for complementary e-beam lithography (CEBL) are described. In an example, method of forming a pattern for a semiconductor structure including forming a pattern of parallel lines above a substrate. The method also includes aligning the substrate in an e-beam tool to provide the pattern of parallel lines parallel with a scan direction of the e-beam tool. The e-beam tool includes a blanker aperture array (BAA) having a staggered pair of columns of openings along an array direction. The array direction has an acute rotation angle from an axis orthogonal to the scan direction. The method also includes forming a pattern of cuts or vias in or above the pattern of parallel lines to provide line breaks for the pattern of parallel lines by scanning the substrate along the scan direction.
