Water filtration may be one of graphene's most directly beneficial capabilities. Now scientists have demonstrated how effective a specially-designed form of graphene can be at purifying water with a pretty challenging test: the filter made water from Sydney Harbour safe to drink in one step.

Seawater is a complex cocktail of useful minerals, but it’s hard to separate the ones we need. Now a team of scientists from Australia and the US has developed a new water desalination technique that can not only make seawater fresh enough to drink, but recover lithium ions for use in batteries.

Plastic’s resilience makes it great for product packaging, but not so great when it ends up in the ocean. Scientists in Sweden are testing a new filter system to catch tiny bits of plastic before they enter natural waterways, and quickly break them down using visible light from the Sun.

Researchers at Rice University have developed a new material that could be used to capture carbon dioxide from the atmosphere. Made from hexagonal-boron nitride (h-BN) and polyvinyl alcohol (PVA), the foam can soak up more than three times its own weight in CO2, and is reusable.

ScienceA new water purification technology developed by researchers at Princeton University doesn't require filters, instead relying on the injection of CO2 gas to change the water's chemistry and separate waste particles based on their electrical charge.
-
Researchers at the University of Manchester have developed a graphene-oxide membrane with a scalable, uniform pore size that can filter out even the smallest salts, giving it potential for producing drinking water from salt water without affecting the flow of the water too much.

Northern Ireland's Mindflood has developed the compact minijam studio platform to provide everything an electronic musician needs to create a beat or track. The first "tek" minijam range is made up of a drum machine, a wavetable synth module, an analog filter, a mixer unit and a portable speaker.

Soon, people in smog alerts could breath easy thanks to a new nanofiber solution developed at NUS. Air filters made from the material can block most small particles while still letting air circulate, and at the same time block UV rays without reducing natural light.

ScienceEngineers at the Washington University in St. Louis (WUSTL) have developed graphene-based biofoam sheets that can be laid on dirty or salty dams and ponds to produce clean drinking water, using the power of the sun.

To combat health risks posed by air pollution, car manufacturers are working to make sure we're able to breathe easy in their cars. Tesla has Bioweapon Defense Mode, and now Audi is getting on board with a new filter that removes particulates, gases and allergens from the air.

A new eco-friendly take-with-you shower is being developed by Japanese company Hotaru. Relying on the company's water purification system, it delivers great pressure and can run on 5 gal (20 L) of water for two weeks.

The all-new Oasis water treatment system brings your filter of choice to your drinking vessel of choice. Filter out harmful bacteria and viruses or just bad taste from inside a water bottle, hydration pack and more.
