The present invention relates to a process for the production of hydrogen gas and a solid carbon product selected from the group consisting of graphene, graphite and mixtures thereof. The process comprises the steps of feeding an educt gas into a plasma section of a reactor in a direction different from the longitudinal axis of the reactor, converting the educt gas into a plasma having a temperature of more than 3,000 K by flowing the educt gas through an electric arc discharge, quenching the plasma and/or gas obtained from the plasma with a cooling rate of more than 1,000 K/s from a temperature of more than 3,000 K to a temperature of below 3,000 K. The educt gas comprises CH<4> and has an atomic H/C ratio of ≥ 4.0. The invention furthermore provides a device for the production of hydrogen gas and a solid carbon product selected from the group consisting of graphene, graphite and mixtures thereof or for the production of hydrogen gas and a modified solid carbon product selected from the group consisting of doped graphene, doped graphite and mixtures thereof.

Devices and methods for processing ultrasound images of manufactured parts to determine cracks in the parts. The devices comprise an imaging device with one or more ultrasonic transducer arrays that emit and receive ultrasound waves at various angles and distances, and a processing circuit that filters, beamforms, and compounds the ultrasound data to generate images of the tubulars. The methods involve insonating the tubulars with plane waves at non-zero or zero angles, applying a specular or anti-specular filter to the ultrasound scans, identifying a wall region between the inner and outer surfaces of the tubulars, and identifying a crack region by the presence of a signal void or a mode conversion of the ultrasound waves. The size of the crack is determined by measuring the dimensions of the crack region or fitting a geometric model to the compounded image.

Devices and methods are described for non-destructive testing of materials and components using multiple imaging modalities, such as ultrasound and optical imaging, to generate three-dimensional data volumes that can identify flaws, such as cracks. The devices comprise an imaging tool with an ultrasound array and an optical system, which are coupled to a first and a second block regions, respectively. The block may be separated by an interface layer that is sonically transparent and optically reflective. The methods involve emitting and receiving ultrasound signals from the ultrasound array, receiving optical signals from the optical system, determining a pose for the imaging tool, and assembling the ultrasound and optical images to create a multimodal image volume assembly. The devices and methods can be used for imaging pipelines and manufactured parts, such as airplane wings, to provide accurate and intuitive information about the structural integrity and environmental impact of the tubulars.
