Abstract:
A solar-powered system includes a support portion; and an evaporation portion having a pumping layer and a photothermal layer. The support portion pumps a fluid to the evaporation portion, the pumping layer evaporates the fluid based on solar power; and the photothermal layer is insulated from the pumping layer.
Abstract:
An atmospheric water harvesting material includes a deliquescent salt, a photothermal agent, and a polymeric hydrogel matrix containing the deliquescent salt and photothermal agent.
Abstract:
Disclosed herein are surface-modified membranes and other surface-modified substrates exhibiting switchable oleophobicity and oleophilicity in aqueous media. These membranes and substrates may be used for variety of applications, including controllable oil/water separation processes, oil spill cleanup, and oil/water purification. Also provided are the making and processing of such surface-modified membranes and other surface-modified substrates.

Embodiments of the present disclosure provide structures or membranes including photothermal nanomaterials, devices including the structure, methods of use, methods of desalination, and the like.
Abstract:
A smart sand includes raw sand particles, synthetic SiO2 particles attached to the raw sand particles, a first material attached to a first set of the synthetic SiO2 particles, a second material attached to a second set of the synthetic SiO2 particles, and a third material attached to the first material. Each of the first to third materials is different from each other.
Abstract:
A solar-powered system including a chamber that is bordered by an evaporation layer and a condensation layer; and a photothermal layer located over the evaporation layer so that sun rays incident on the photothermal layer are transformed into heat and the heat is supplied to the evaporation layer for evaporating water. The sun rays incident on the photothermal layer do not pass through the condensation layer prior to arriving at the photothermal layer.
Abstract:
An osmotic energy conversion system includes a housing having a first inlet and a second inlet, an MXene lamellar membrane located inside the housing and configured to divide the housing into a first chamber and a second chamber, and first and second electrodes placed in the first and second chambers, respectively, and configured to collect electrical energy generated by a salinity-gradient formed by first and second liquids across the MXene lamellar membrane. The first chamber is configured to receive the first liquid at the first inlet and the second chamber is configured to receive the second liquid at the second inlet. The first liquid has a salinity lower than the second liquid, and the MXene lamellar membrane includes plural nanosheets of MXene stacked on top of each other.
Abstract:
An integrated photovoltaic (PV) panel-water sorption layer system that includes a PV panel having a front face that is configured to receive solar light for generating electrical current, and a back face that is opposite to the front face; and an atmospheric water harvesting device attached to the back face of the PV panel. The atmospheric water harvesting device is configured to cool down the PV panel by evaporating absorbed atmospheric water based on heat received from the PV panel.
