Apparatuses and methods for producing covetic materials by exciting a hydrocarbon gas with pulse microwaves to form hydrocarbon radicals in a hot first region of a microwave reactor. Graphene nanoplatelets are formed by the nucleation, growth and assembly of the hydrocarbon radicals, and contact a metal melt introduced downstream of the hot region to produce a mixture of molten metal and graphene nanoplatelets which assemble in-flight to form covetic materials. Graphene planes are infused in the metal matrix to achieve carbon loadings of at least 60%.

A system for determining the muzzle velocity of a firearm includes a firearm having a barrel and a gas block. A first sensor is arranged at a gas block and is configured to determine a change in pressure within the gas block. A second sensor is positioned at an end of the barrel of the firearm for detecting a pressure wave produced by a projectile fired by the firearm. A control unit is in communication with the first sensor and the second sensor and is configured to determine a velocity of the projectile based on information received from the first sensor and the second sensor.

System for determining muzzle velocity of a firearm

A firearm having an aim-compensation system. The firearm includes a barrel and is configured to fire a projectile. The firearm further includes a sensor disposed on the firearm that determines an orientation of the firearm. The firearm further includes a control unit that determines an intended point-of-aim of the firearm and an actual expected point-of-aim of the firearm based on the orientation of the firearm, and the control unit determines a differential of the intended point-of-aim and the actual expected point-of-aim. The firearm further includes a muzzle device arranged on the barrel which is in communication with the control unit, wherein, when the projectile is fired, the muzzle device directs a gas toward the projectile in an amount and direction based on the differential determined by the control unit so as to exert an aerodynamic force on the projectile to alter the trajectory of the projectile towards the intended point-of-aim.

A duoplasmatron ion source with a partially ferromagnetic anode can be used in multiple applications, including the production of negative ions for secondary ion mass spectrometers and particle accelerators. A partially ferromagnetic anode, which may be embodied in a partially ferromagnetic anode insert, includes a ferromagnetic and non-ferromagnetic portions joined together at a juncture, with an ion extraction aperture defined in the ferromagnetic portion and the juncture being laterally offset from the aperture. An asymmetric magnetic field produced by the partially ferromagnetic region facilitates extraction of charged ions from the central, most intense region of a source plasma in the duoplasmatron ion source. A ferromagnetic conical portion of the anode defines the ion extraction aperture in order to maximize the magnetic field in the vicinity of this aperture.

A primary ion source subassembly for use with a secondary ion mass spectrometer may include a unitary graphite ionizer tube and reservoir base. A primary ion source may include a capillary insert defining an ionizer aperture. An ionizer aperture may be centrally arranged in an outwardly protruding conical or frustoconical surface, and may be overlaid with a refractory metal coating or sheath. Parameters including ionizer surface shape, ionizer materials, ionizer temperature, and beam stop plate orifice geometry may be manipulated to eliminate ghost images. A graphite tube gasket with a dual tapered surface, or an externally threaded graphite tubular connecting body, may promote sealing of a source material cavity.

A pressure barrier comprising a window with a first side and a second side, a main section comprising a length, a first end, and a second end opposite the first end, a first gradient compression section adjacent to the first end of the main section, and a second gradient decompression section adjacent to the second end of the main section is described. A pressure difference can be formed between the first and second side of the window. The window can comprise a dielectric material, where an average dielectric constant of the gradient compression section increases toward the main section, and an average dielectric constant of the gradient decompression section decreases away from the main section. A microwave propagating in a propagation direction can enter the pressure barrier at the gradient compression section and exit the pressure barrier through the gradient decompression section.

The present invention relates to a novel method for analyzing nucleic acid sequences based on real-time detection of DNA polymerase-catalyzed incorporation of each of the four nucleotide bases, supplied individually and serially in a microfluidic system, to a reaction cell containing a template system comprising a DNA fragment of unknown sequence and an oligonucleotide primer. Incorporation of a nucleotide base into the template system can be detected by any of a variety of methods including but not limited to fluorescence and chemiluminescence detection. Alternatively, microcalorimetic detection of the heat generated by the incorporation of a nucleotide into the extending template system using thermopile, thermistor and refractive index measurements can be used to detect extension reactions.

An ion guide generates a radio frequency (RF) field to radially confine ions to an ion beam along a guide axis as the ions are transmitted through the ion guide. The effective potential of the RF field has potential wells distributed along the guide axis. The RF field is constructed such that the potential wells move in an axial direction toward an exit end of the ion guide.
