#zrodlo

Researchers have developed a first-of-its-kind technique for creating entirely new classes of optical materials and devices that could lead to light bending and cloaking devices -- news to make the ears of Star Trek's Spock perk up. Using DNA as a key tool, the scientists took gold nanoparticles of different sizes and shapes and arranged them in two and three dimensions to form optically active superlattices. The structures could be programmed to exhibit almost any color across the visible spectrum.

Radioactivity from oil and gas wastewater persists in Pennsylvania stream sediments

Added: 19.01.2018 14:11 | 0 views | 0 comments

#zrodlo

More than seven years after Pennsylvania officials requested that the disposal of radium-laden fracking wastewater into surface waters be restricted, a new study finds that high levels of radioactivity persist in stream sediments at three disposal sites. Radioactivity at these sites is 650 times higher than at unaffected sites upstream. The contamination comes from conventional, or non-fracked, oil and gas wastewater, which, under current state regulations, can still be treated and discharged into streams.

#zrodlo

Researchers have described a new technique to improve chemical stability of electrode materials which can extend the lifespan by employing a very little amount of metals. Using computational chemistry and experimental data, the team observed that local compressive states around the Sr atoms in a perovskite electrode lattice weakened the Sr-O bond strength, which in turn promote strontium segregation.

Slow 'hot electrons' could improve solar cell efficiency

Added: 16.01.2018 15:45 | 0 views | 0 comments

#zrodlo

Photons with energy higher than the 'band gap' of the semiconductor absorbing them give rise to what are known as hot electrons. The extra energy is lost very fast, as it is converted into heat so it does not contribute to the voltage. Researchers have now found a material in which these hot electrons retain their high energy levels for much longer.
