Alkylation or arylation of selenide or diselenide anions is a well-established method to obtain organoselenium compounds. Nevertheless, detecting inorganic selenium anions using 77Se NMR is still a challenge. In a previous work, alkylation of Na2Se w

The cetane number (CN) is one of the most important parameters regarding diesel fuel oil quality, mainly ignition properties. Traditionally, the CN determination is performed by a quite laborious and high-cost method on an explosion engine. On the ot

The success of cancer treatment is directly related to early detection before symptoms emerge, although nowadays few cancers can be detected early. In this sense, 1H nuclear magnetic resonance (1H NMR)-based metabonomics was used to identify metaboli
