Iridescent films made from wood pulp cellulose may replace toxic dyes
Intensely coloured low-cost films made from cellulose could be used in place of toxic dyes, or to detect counterfeit materials.
Label-free, sequence-specific, inexpensive fluorescent DNA sensors
(Phys.org) —Using principles of energy transfer more commonly applied to designing solar cells, scientists at the U.S. Department of Energy's Brookhaven National Laboratory have developed a new highly sensitive ...
Anti-counterfeit 'fingerprints' made from silver nanowires
Unique patterns made from tiny, randomly scattered silver nanowires have been created by a group of researchers from South Korea in an attempt to authenticate goods and tackle the growing problem of counterfeiting.
Researchers develop new kind of polymers that can be created using solid-state polymerization of organic dye molecules
Israel researcher: Elusive Biblical blue found
An Israeli researcher says she has identified a nearly 2,000-year old textile that may contain a mysterious blue dye described in the Bible, one of the few remnants of the ancient color ever found.
Amplifying our vision of the infinitely small
Richard Martel and his research team at the Department of Chemistry of the Université de Montréal have discovered a method to improve detection of the infinitely small. Their discovery is presented in the ...
The chemistry of color: Energy researcher develops dye-based solar cells
(Phys.org) —UW-Madison researchers working at the intersection of basic and applied science focus on key factors like cost, environmental impacts ... and sometimes, color.
Lab-made complexes are 'sun sponges'
In diagrams it looks like a confection of self-curling ribbon with bits of bling hung off the ribbon here and there. In fact it is a carefully designed ring of proteins with attached pigments that self-assembles ...
Self-healing solar cells 'channel' natural processes
To understand how solar cells heal themselves, look no further than the nearest tree leaf or the back of your hand.
Watching molecule movements in live cells
The newly developed STED-RICS microscopy method records rapid movements of molecules in live samples. By combining raster image correlation spectroscopy (RICS) with STED fluorescence microscopy, researchers ...
Molecular chains hypersensitive to magnetic fields
Researchers of MESA+, the research institute for nanotechnology of the University of Twente, in cooperation with researchers of the University of Strasbourg and Eindhoven University of Technology, are the ...
Development of nonvolatile liquid anthracenes for facile full-colour luminescence tuning
A research team from the National Institute for Materials Science has developed a full-colour tunable luminescent liquid material with excellent photostability based on anthracene, which is a general organic ...
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, ...
Fast pollutant degradation by nanosheets
(Phys.org) —Waste from textile and paint industries often contains organic dyes such as methylene blue as pollutants. Photocatalysis is an efficient means of reducing such pollution, and molybdenum trioxide ...
