  • Patent number: 11433372
    Abstract: The present invention provides a stationary phase for solid-phase microextraction (SPME) devices based on nickel and titanium alloy nuclei and a metal-organic framework (MOF) exterior, which may be used for chromatographic analysis in environmental, food, etc. applications. The method of preparation of the stationary phases consists of a number of steps which provide a covalent adhesion of the MOF to the nickel/titanium alloy. In these stationary phases, the metal-organic framework is the only component that comes into contact with the sample to be analysed. The interior of the stationary phase is executed in nitinol and endows the system with thermal and mechanical stability, this being the first time that it is used to support a metal-organic framework, and presenting extractive advantages in comparison with commercial SPME stationary phases.

  • Patent number: 10230940
    Abstract: A method for determining the complex amplitude of the electromagnetic field associated with a scene, comprising a) capturing a plurality of images of the scene by means of a photographic camera, the images being focused in planes of focus arranged at different distances, wherein the camera comprises a lens of focal length F and a sensor arranged at a certain distance from the lens in its image space, taking at least one image pair from the plurality of images and determining the accumulated wavefront to the conjugate plane in the object space corresponding to the intermediate plane with respect to the planes of focus of the two images of the pair.

  • Publication number: 20150030706
    Abstract: The present invention starts with a method for obtaining organic extracts of the Artemisia absinthium L. plant, which includes: a methodology phase for producing said plant, an extraction phase during which said essential oil and a non-volatile extract are obtained, and a phase of extracting supercritical extracts with CO2, and refers specifically to the use of the essential oil and/or the supercritical extract extracted as fungicides against phytopathogenic fungi. For said purpose, the Artemisia absinthium L. plant is used, specifically the Candial variety from Teruel and/or Sierra Nevada in Spain. The present invention also relates to the aqueous residue generated during said method, which includes an organic compound which in turn contains (Z)-2,6-dimethylocta-5,7-diene-2,3-diol as an active organic compound against nematodes. The method for obtaining said organic portion and the corresponding active organic component thereof is protected by the present application.

  • Patent number: 8471897
    Abstract: The invention relates to a method for calculating the focal stack associated with an object space from the plenoptic function thereof, using a sum transform along the length of constrained planes in discrete hypercubes, which allows the computing time to be considerably reduced. The invention also relates to a method for increasing the resolution of the focal stack obtained. In addition, the invention relates to two methods for the real-time recovery of the depths and moduli and phases of the complex amplitude of the wavefront respectively in each position of the surfaces of a three-dimensional scene and to a system adapted for carrying out the aforementioned methods.

  • Publication number: 20100091146
    Abstract: A system consisting of a phase camera with microlenses placed in the focal point of a converging lens, wherein the camera data, processed using a combined Fourier “Slice” and fast Fourier transform edge detection technique, provide both a three-dimensional wavefront map and a real scene depth map within a broad range of volumes. The invention is suitable for use in any field where wavefronts need to be known such as earth-based astronomical observation, ophthalmology, etc., as well as in fields requiring metrology, e.g. real scenes, CCD polishing, automobile mechanics, etc. The invention is applied to the particular case of atmospheric tomography using ELTs (large-diameter telescopes: 50 or 100 meters).
