Engineered sand zaps storm water pollutants

University of California, Berkeley, engineers have created a new way to remove contaminants from storm water, potentially addressing the needs of water-stressed communities that are searching for ways to tap the abundant ...

Researchers develop new way to clear pollutants from water

When it comes to removing very dilute concentrations of pollutants from water, existing separation methods tend to be energy- and chemical-intensive. Now, a new method developed at MIT could provide a selective alternative ...

Bacteria adapt and evade nanosilver's sting

(Phys.org) —Researchers from UNSW have cautioned that more work is needed to understand how micro-organisms respond to the disinfecting properties of silver nano-particles, increasingly used in consumer goods, and for medical ...

Titanate cigarette filter could be safer

(PhysOrg.com) -- While current cigarettes are made with a filter created from cellulose acetate which absorbs things like nicotine, tar, and polycyclic aromatic hydrocarbons, Chinese researchers have discovered that nanomaterials ...

Characterisation of the structure of graphene

Graphene, the world's first two-dimensional material, is many times stronger than steel, more conductive than copper, lightweight, flexible and one million times thinner than a human hair.
