Liquid: a liquid filter

Water filtration for human consumption and industrial wastewater purification accounts for huge electricity consumption and CO2 emissions. Passing water through a porous membrane to filter out particles larger than water molecules is a common water processing method. A problem with this filtration method is that membranes are susceptible to fouling (clogging by the filtrates). To…

Truly recycling plastic with reversible polymer chemistry

In the ideal world, recycling plastics should break the polymers back to monomers, its original building blocks. Monomers could then be made into new plastics over and over. The team from the Lawrence Berkeley National Laboratory in California brought us one step closer to the dream of closed-loop, zero-waste plastics. Researchers utilised a family of…

Mussels Inspire Self-Healing Plastics

They’re strong, flexible and tough – mussels have proved they’ve got muscle. Recently they’ve inspired researchers to create a new plastic which could potentially heal itself. Plastics are made of polymers – long, repetitive chains of atoms which can stretch and then relax back to their original shape. Designing a polymer is a trade-off between…
