Technically known as fillers, these small hydrogel tubes can be made from synthetic polymer ... Less pollution, however, means more residues in biodiesel storage tanks — being denser, the water is ...

Finally, the new loofah-like material was tested on samples polluted with organic dyes, heavy metals, oil and microplastics. In all of the tests, the gel made the water substantially cleaner.

In the search for innovative materials that enable the harvesting of water, hydrogels that can absorb moisture from the air – hygroscopic hydrogels – have attracted the attention of researchers.

And under lower light conditions, replicating partly cloudy skies, it took 15 to 20 minutes for the material to release a similar amount of stored water. Finally, the new loofah-like material was ...

but because their molecules stick to the gel, they don't get expelled when the water is released at warmer temps. Droplets of oil pollution don't get drawn in in the first place, as the (then ...

Thermosensitive hydrogels are polymeric materials capable of absorbing a large amount of water, depending on the temperature to which they are exposed, and expelling it free of salts and ...

To combat this emerging pollutant, researchers at the Indian Institute of Science (IISc) have designed a sustainable hydrogel to remove microplastics from water. The material has a unique ...

The researchers also observed distinctions in the movement of water on the hydrogel fiber surface compared to that on glass. On the glass, droplets advanced as a cohesive unit with successive ...

What’s more, that same collected moisture can be heated, condensed, and subsequently collected into “ultrapure” water. Hydrogels—materials composed mostly of water alongside cross-linked ...
