Cząsteczki z przestrzeni – Gaz pierwotny
Cząsteczki z przestrzeni – Gaz pierwotny – Has been confirmed the hypothesis about the origin of molecules from space. The researchers were able to discover the so-called. Primary gas, which was created shortly after the Big Bang, it consists of hydrogen and its heavier isotope deuterium. This finding confirms that in the Big Bang were created only the lightest chemical elements, hydrogen and helium. Heavier elements appeared only after 100 million years.
Tunel Brukselski – Eksperyment z fotokatalizą
Tunel Brukselski – Eksperyment z fotokatalizą – In 09.2011. European experts began their experiment in the Brussels tunnel, through which passes every day 25 thousand. cars. 100 meter length of building was covered with cement with titanium dioxide TiO2, which is the source of a chemical process called photocatalysis, acts as a catalyst driven by solar radiation (UV).
Łańcuch DNA – Drabiny z milionami szczebli
Łańcuch DNA – DNA strands looks like spiral ladders with the millions rungs, each of which carries the instructions written by chemical code. If we could unravel and stretch the DNA of a single human cell, measure the approx. 2 meters, its thickness, however, would amount to approx. 0.000002 mm. Chain DNA from the body of one man is 16 times longer than the path from Earth to the Moon.
Przeciwmalaryczne skuteczne lekarstwo – Wyizolowana chinina
Przeciwmalaryczne skuteczne lekarstwo – Wyizolowana chinina – One of the first effective drugs for malaria was the bark of the Peruvian cinchona tree (Cinchona) containing alkaloid – quinine. Its action convinced the Jesuits and approx. 1640. Brought it from South America. to Europe. It was not until 1820. Quinine isolated the French chemists – Pierre Joseph Pelletier and Joseph Bienaime Caventou.
