Influence of sunlight exposure on rhizophora dye solution

(Phys.org) —Natural dyes have been used as the colouring of natural fibres, in cosmetic products, to produce ink, watercolour and artist's paints. Natural dyes produce an extraordinary diversity of rich and complex colour. ...

DNA constructs antenna for solar energy

Researchers at Chalmers University of Technology have found an effective solution for collecting sunlight for artificial photosynthesis. By combining self-assembling DNA molecules with simple dye molecules, the researchers ...

Flexible polymer opals

A synthetic material which mimics the brightest and most vivid colours in nature, and changes colour when twisted or stretched, has been developed by researchers at the University of Cambridge, and could have important ...

Multi-component nano-structures with tunable optical properties

(PhysOrg.com) -- Scientists at the U.S. Department of Energy's Brookhaven National Laboratory report the first successful assembly of 3-D multi-component nanoscale structures with tunable optical properties that incorporate ...

Novel technique informs drug delivery research

University College Dublin researchers led by Conway Fellow, Professor David Brayden have shown that a candidate drug delivery polymer may have potential for oral or topical use. These findings were recently published in the ...

'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. ...
