  • Publication number: 20230302408
    Abstract: Various systems and processes are directed to filtering organic compounds using nanoporous membranes and osmosis. In various implementations, the nanoporous membrane can be trained on one or more organic compounds such that the nanoporous membrane preferentially allows the one or more organic compounds to permeate the nanoporous membrane to the exclusion of other compounds. In some implementations, the nanoporous membrane is trained on ethanol such that the nanoporous membrane preferentially allows ethanol to permeate the nanoporous membrane to the exclusion of other compounds, such as water or other compounds or mixtures. In some implementations, the selective ethanol permeation of the nanoporous membrane may occur even where the other compounds have smaller molecules than ethanol.

  • Patent number: 11571659
    Abstract: A method for producing electrical energy. An electrolyte solution having a first concentration CA of a solute is placed in a first vessel having an electrode arranged so the electrode is contacted with the electrolyte solution of concentration CA. An electrolyte solution having a concentration CB of the same solute is placed in a second vessel having an electrode arranged so the electrode comes in contact with the electrolyte solution of concentration CB, the concentration CB being lower than the concentration CA. The first and the second vessels are separated by a membrane, the membrane having at least one nanochannel arranged to allow diffusion of the electrolyte solution from the first vessel to the second vessel through the at least one nanochannel. An inner surface of the at least one nanochannel is formed of at least one titanium oxide. Electrical energy generated by a potential difference existing between the electrodes is captured using a device having the first and second vessels.

  • Publication number: 20220063192
    Abstract: The present invention relates to a system for controlled deposition of a fluid on a substrate and also to a method employing the system. The system comprises: a nanoinjector, a mechanical resonator fixed to the nanoinjector, the mechanical resonator being adapted to detect contact between the nanoinjector and the substrate, control means of the mechanical resonator comprising: an excitation means adapted to cause the mechanical resonator to oscillate at an oscillation frequency (fi), a detector means adapted to detect the oscillation of the mechanical resonator, a regulator means adapted to adjust the contact between the nanoinjector and the substrate by controlling the oscillation of the mechanical resonator.

  • Patent number: 10960354
    Abstract: The present invention relates to a device for producing electrical energy, including two vessels A and B intended for each receiving a concentrated electrolyte solution CA and CB in the same solute and each including an electrode arranged so as to come into contact with the electrolyte solution, a membrane separating the two vessels, said membrane including at least one nanochannel arranged to allow the diffusion of the electrolytes from one vessel to the other through said one or more nanochannels, and a device making it possible to supply the electrical energy spontaneously generated by the differential in potential that exists between the two electrodes, characterised in that at least one portion of the inner surface of the one or more nanochannels is essentially made up of at least one titanium oxide. The present invention likewise relates to a method for producing electrical energy using said device.
