'Holey' Nanosheets for Wastewater Dye Removal

(PhysOrg.com) -- Researchers have discovered that extremely thin sheets of nickel oxide with hexagonally shaped holes can absorb hazardous dyes from wastewater nearly as well as the best traditional methods, but are recyclable. ...

Affordable solar technology

An innovative Oxford company has developed new solar cell technology that is manufactured from cheap, abundant, non-toxic and non-corrosive materials and can be scaled to any volume.

Ray of light could lead to next generation of superconductors

A superconductor, which can move electrical energy with no wasteful resistance, is the holy grail of cost-effective, efficient, and "green" power production. Unlike traditional conductors such as copper or silver, which waste ...

Graphene 'onion rings' have delicious potential

Concentric hexagons of graphene grown in a furnace at Rice University represent the first time anyone has synthesized graphene nanoribbons on metal from the bottom up—atom by atom.

A single-digit-micrometer thickness wood speaker

In a recent report on Nature Communications, Wentao Gan and a team of researchers at the departments of materials science and engineering in the U.S. have detailed the use of an ultrathin film of natural wood to create an ...

A touch of gold makes glass more see through

(PhysOrg.com) -- Physicists at the King's College London have discovered a means of making glass more transparent - by coating it in a thin layer of gold.
