  • Patent number: 12101887
    Abstract: In an embodiment, a method of manufacturing (100) is described. The method comprises providing (102) a first layer defining a first inner surface (203a) and a first outer surface (203b), a second layer defining a second inner surface (205a) and a second outer surface (205b), and an electrical component (206) positioned on the first inner surface or the second inner surface. The method further comprises attaching (104) the first and second layers together to create a device (200) comprising the first and second layers, wherein the first outer surface and the second outer surface define an external surface of the device. The device further comprises a sealed portion (208) defined by liquid-tight attachment between the first and second inner surfaces. In use of the device, the sealed portion prevents liquid ingress into the device between the first and second layers towards the electrical component.

  • Patent number: 9957288
    Abstract: The present invention relates to compounds which can be used to control plant development. Indeed, the present invention discloses a new class of pyrabactin analogues which have a physiological effect on—for example—seed germination, and/or stomatal closure, and/or have developmental effects on root and shoot development and organogenesis. Hence, the latter compounds can be used to control plant development such as—for example—increasing the tolerance of plants to drought stress or to control physiological phenomena such as pre-harvest sprouting, tolerance to pathogens etc.

  • Patent number: 9919271
    Abstract: The disclosure relates to efficient methods of controlling biological conversions while simultaneously removing and converting some of the generated products. More specifically, and, for example, the disclosure discloses electrochemical processes to remove and capture potentially toxic ammonium during anaerobic digestions and to remove and capture carboxylic acids during bioethanol production. The disclosure can, thus, be used to enhance bioproduction processes via controlling pH and/or reduction/oxidation, in combination with in situ product recovery.

  • Patent number: 9163868
    Abstract: A method is provided for storing thermal energy or increasing the thermal energy of a heat pump using reversible chemical reactions in which inorganic oxoacid compounds and/or their salts are hydrolysed and condensed or polymerized in order to release and capture heat.
