Using a new kind of hydrogel material, researchers at the University of Texas at Austin have pulled water out of thin air at temperatures low enough to be achieved with sunlight. Atmospheric water harvesting draws water from humidity in the air. The material is a hydrogel, a polymer network that naturally retains a lot of water.

While effective at keeping wine inside a bottle, suberin’s most important function in plants is to control water and nutrient transportation and keep pathogens out. Plants use different polymers in constructing cell walls, each with unique qualities essential for growth and survival. Chang-Jun Liu.

Researchers at Georgia Tech have developed an inexpensive and simple prototype of a triboelectric nanogenerator that could be used to produce energy from ocean waves by making use of contact electrification between a patterned plastic nanoarray and water. The tank is filled with deionized water. Or a surface charge density of 4.5

But we have demonstrated that by directly using power generated by the cold universe, we can chill water to cool buildings by as much as 5 ºC during the day without electricity and light the night without wires or batteries. In the case of moving water, a turbine harvests the energy in the flow to generate hydroelectricity.

After capturing carbon dioxide, the materials give it up easily so that the CO 2 can be used in making other substances, or permanently isolated from the environment. It is now widely accepted that anthropogenic CO 2 , due to its role as a greenhouse gas, is the major contributor to climate change. —Goeppert et al.

Secondary recovery techniques generally injecting water or gas to displace oil and drive it to a production wellbore, resulting in the recovery of 20 to 40% of the original oil in place. During primary production, natural reservoir pressure or gravity pushes oil into the wellbore. Gas injection (e.g., Jaramillo et al. Jaramillo et al.
