Perovskite solar cells: Perfection not required

Added: 16.01.2018 11:11 | 0 views | 0 comments

#zrodlo

Metal-organic perovskite layers for solar cells are frequently fabricated using the spin coating technique on industry-relevant compact substrates. These perovskite layers generally exhibit numerous holes, yet attain astonishingly high levels of efficiency. The reason that these holes do not lead to significant short circuits between the front and back contact has now been discovered.

Scientists have, in recent decades, pinpointed neurons called 'place cells' in our brains that encode our own location in the environment, but how our brains represent the positions of others has been a mystery. New research in bats, reveals a sub-population of neurons that encode the specific location of other bats that are flying nearby.

High performance CNT catalyst relating to its electroconductivity

Added: 16.01.2018 9:56 | 0 views | 0 comments

#zrodlo

Biofuels were obtained from Jatropha Oil using carbon nanotube (CNT) catalyst, which showed efficient cracking activity. The performance was activated by the high stability, metal sites, acid sites, electroconductivity, and coking tolerance of CNT. Two cracking circulations were found in the hydroprocessing. Meanwhile, the sulphur-free process was eco-friendly.

Scientists discovered a dinosaur fossil with feathers so well-preserved that they were able to see the feathers' microscopic color-bearing structures. By comparing the shapes of those feather structures with the structures in modern bird feathers, they're able to infer that the new dino, Caihong juji ('rainbow with the big crest') had iridescent rainbow feathers like a hummingbird.

#zrodlo

An international team of citizen scientists and professional astronomers has discovered a system of at least five massive exoplanets, orbiting the Sun-like star K2-138. This planetary system is approximately 792 light-years away toward the constellation Aquarius. A paper reporting this discovery is published in the Astronomical Journal (arXiv.org preprint). K2-138, also known as 2MASS J23154776-1050590 [...]

#zrodlo

Conjugated tetraenes are important key substructures in electronic materials, natural products and pharmaceutical molecules. However, they are difficult to synthesize. Now, researchers in Japan have achieved a new synthetic route of conjugated tetraenes from inexpensive and easily available 1,3-butadiene and substituted acetylenes by a one-pot approach under mild conditions.

#zrodlo

Phytoplankton blooms are one of the most important factors contributing to the efficiency of the carbon pump in the North Atlantic Ocean. To better understand this phenomenon, researchers have developed a new class of robots able to collect data in the ocean throughout the year. Using these unparalleled data, the researchers have identified the starting point for the explosive spring phytoplankton bloom.

Surfers three times more likely to have antibiotic-resistant bacteria in guts

Added: 15.01.2018 20:23 | 0 views | 0 comments

#zrodlo

Scientists compared fecal samples from surfers and non-surfers to assess whether the surfers' guts contained E. coli bacteria that were able to grow in the presence of the antibiotic cefotaxime. Cefotaxime has previously been prescribed to kill off these bacteria, but some have acquired genes that enable them to survive this treatment. The study found that 13 of 143 (9 percent) of surfers were colonized by these resistant bacteria, compared to just four of 130 (3 percent) of non-surfers swabbed.
