Notable achievement of our chemists [The first work of Ukrainian chemists, published in the journal Nature]
A new world record for the length of the carbon bond C-C currently is 1.704 Ao (typically 1,540 Ao). Remarkable is that despite on the record bounding length, synthesized compounds are stable even at elevated temperatures. The result was so unpredictable that it was necessary to undertake specific study causes of anomalous stability and this has led to fundamental discovery.
Book and Copyright Day Celebration
Authors, publisher, teachers, librarians and everyone who works in this sphere celebrate Book Day. It is celebrated in 190 countries. For the first time it was celebrated in Catalonia (Spain) in 1996, where there is a nice tradition to give a person you like a book and roses in Saint George Day and it has been celebrating more than 80 years.
