Thioamides and selenoamides with chirality solely due to hindered rotation about the C-N bond: enantioselective complexation with optically active hosts
PublicationBariera rotacji wokół wiązania C-N w tioamidach jest średnio o 3-5 kcal/mol wyższa niż w odpowiednich amidach, a w analogicznych selenoamidach wzrasta jeszcze o 1 kcal/mol. Dzięki temu związki te występują w dwu enancjomerycznych formach, których wzajemna przemiana zachodzi w wyniku rotacji wokół wiązań C-N. Bariera rotacji jest wystarczająco wysoka, aby można było podjąć próbę ich rozdziału na enancjomery w temperaturze pokojowej....

Experimental certification of more than one bit of quantum randomness in the two inputs and two outputs scenario
PublicationOne of the striking properties of quantum mechanics is the occurrence of the Bell-type non-locality. They are a fundamental feature of the theory that allows two parties that share an entangled quantum system to observe correlations stronger than possible in classical physics. In addition to their theoretical significance, non-local correlations have practical applications, such as device-independent randomness generation, providing...
