    摘要: A planar membrane cartridge includes a support and a semi-permeable membrane layer. The support includes a first layer attached to a second layer and defining a front face and a back face of the support. At least one of the first layer and the second layer form a first embossment and a second embossment. Respective back faces of the first layer and the second layer are attached to each other along edges of the first embossment and of the second embossment, such that the first embossment defines a fluid compartment between the first layer and the second layer and the second embossment defines an internal channel between the first layer and the second layer which is isolated from the fluid compartment. An area of the first layer corresponding to the first embossment is covered by the semi-permeable membrane layer.

    摘要: A method of enhancing hydrophilicity of a hydrophobic polymer material includes pre-treating the hydrophobic polymer material. The pre-treating includes treating the hydrophobic polymer material with a first atmospheric pressure plasma discharge in a first atmosphere including carbon dioxide to obtain a pre-treated polymer material. The method includes treating the pre-treated polymer material with a second atmospheric pressure plasma discharge in a second atmosphere in which an aerosol of an amine is introduced; the amine includes at least one hydrocarbon substituent. A substrate is provided that includes a hydrophobic polymer material having a modified interface. The modified interface includes amine functional groups grafted on the hydrophobic polymer material, the modified interface having a surface energy, which, measured after immersion in water at 20° C. for 3 days, differs from a surface energy of the hydrophobic polymer material by 20 mN/m or less.

    摘要: A smart grid management system and method where aggregators do not need to have knowledge about the topology of the electricity grid, the physical location of the end-points they control, or the congestion level of the grid. Instead, the smart grid system and method provides maximum freedom of operation to the aggregators to balance electricity supply and demand in such a way that the danger is reduced or it is even impossible for the aggregators to endanger voltage levels at the distribution system operator (DSO) level or the capacity levels at the transmission system operator (TSO) level. The distribution system operator is allowed to block, interrupt, or change the communication between aggregator and device based on a dual stage-gate control.

    摘要: A method of enhancing hydrophilicity of a hydrophobic polymer material includes pre-treating the hydrophobic polymer material, comprising treating the hydrophobic polymer material with a first atmospheric pressure plasma discharge in a first atmosphere. The first atmosphere includes ammonia to obtain a pre-treated polymer material. The method includes treating the pre-treated polymer material with a second atmospheric pressure plasma discharge in a second atmosphere in which an aerosol of a carboxylic acid is introduced. A substrate is provided as well, the substrate including a hydrophobic polymer material having a modified interface, wherein the modified interface includes carboxylic functional groups grafted on the hydrophobic polymer material, the modified interface having a contact angle with water, which, measured after immersion in water at 20° C. for 3 days, is at least 25° less than a contact angle with water of the hydrophobic polymer material.
