N-N single bond, ring formation of some 2-amino-1,4-benzoquinones, or interactions between two reducible groups in a molecule. Polarographic reduction of pesticides has been used to study their adsorption on lignin, to determine their bioavailability in applications in forest nurseries. Studies of alkaline cleavage of lignin at room temperature will form a basis for the use of lignin (which is a renewable raw material) for future industrial applications. He has won numerous awards, including the prestigious 1975 Benedetti–Pichler award given annually by the American Microchemical Society, as well as numerous visiting professorships at institutions around the world. He has been a prolific author with well over 400+ papers and 15 books published, many considered classics in electrochemical analysis. Petr has been a member of the editorial board of the Microchemical Journal, has published on a regular basis, and has critically reviewed many manuscripts and books. He had many master and Ph.D. students including James Rusling, William James Bover, Melek Sirin Baymak, Hayati Celik, Nuha Salem and many more.
