Chemistry students discover new way of identifying hydrogen peroxide
(Phys.org) —Peroxide-based explosives were used during the London bombings in July 2007. They are difficult to detect using traditional instruments based in airports, for example, as their chemical structure ...
Seeing protein synthesis in the field
(Phys.org) —Caltech researchers have developed a novel way to visualize proteins generated by microorganisms in their natural environment—including the murky waters of Caltech's lily pond, as in this ...
Dye-sensitized solar cell absorbs a broad range of visible and infrared wavelengths
Dye-sensitized solar cells (DSSCs) rely on dyes that absorb light to mobilize a current of electrons and are a promising source of clean energy. Jishan Wu at the A*STAR Institute of Materials Research and ...
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 ...
