A photodialysis device that can desalinate saline streams is described herein. The device can have a desalination rate that is significantly faster than current solar thermal desalination technology. Salt is removed from water by passing ionic current derived from sunlight through this water using dye-sensitized membranes. The device can serve as a distributed, low-cost technology that can efficiently and effectively desalinate low salinity sources of water, which is particularly useful for agriculture and drinking water applications.

Systems and methods for integrated solar photodialysis

Provided are methods of making aliphatic or aromatic compounds (e.g., small molecules or polymers) having one or more amine groups and/or imine groups. A method of the present disclosure is an electrohydrogenation method, where a potential is applied to an aliphatic or aromatic compound (e.g., small molecule or polymer) having one or more nitrile groups, where after the potential is applied one or more of the nitrile groups are reduced to an amine or imine. The electrohydrogenation may be carried out using non-pulsed or pulsed potential waveforms.

Electrohydrogenation of nitriles

Methods of making aliphatic compounds having two or more electron withdrawing groups and compositions comprising aliphatic organic compounds having one or more electron withdrawing groups. The methods are based on electrohydrodimerization of aliphatic olefinic compounds having one or more electron withdrawing groups using pulsed potential waveforms. A method may produce adiponitrile by electrolysis of acrylonitrile using pulsed waveforms. A composition may be an electrochemically produced organic phase composition. A composition may comprise one or more undesirable products, such as, for example, propionitrile, AN-derived oligomers, and the like. A composition may not have been subjected to any purification and/or separation after electrochemical production of one or more aliphatic compounds comprising two or more electron withdrawing groups.

Provided are electrochemical cells for hydrogen production and methods for hydrogen production. The electrochemical cell and methods use a mediator that may have a reversible redox potential lying outside the onset of the oxygen evolution reaction (OER) and the hydrogen evolution reaction (HER). Also, provided are systems for generating hydrogen and water from oxygen and generating water from oxygen and hydrogen.

Methods and electrochemical cells for redox mediated hydrogen production

The present invention concerns a membrane-less electrolyzer comprising a fluidic channel for receiving an electrolyte fluid; a first electrode and a second electrode located inside the fluidic channel, the first and second electrode permitting to extract a first gas and a second gas inside the fluidic channel from the electrolyte fluid, the first electrode and second electrode being separated by solely a surrounding fluid in the fluidic channel or the electrolyte; and a first fluidic transport channel for transporting the first gas to a first outlet and a second fluidic transport channel for transporting the second gas to a second outlet.
