W roku akademickim 2023/2024 - konsultacje poprzez Teams - bez umawiania się, proszę po prostu zadawać pytania, będę odpowiadał na bieżąco, w miarę możliwości czasowych. In the academic year 2023/2024 - consultations through Teams - no need to register or book, just ask questions through the chat, I will answer as soon as possible, depending on my schedule. Odbywają się tylko po uprzednim umówieniu się na nie (przez Teams/mail/osobiście). Pokój 346, Gmach Chemii, środy g. 13:15 i czwartki g.15:15. Inne terminy tylko po kontakcie mailowym minimum dwa dni wcześniej. Jeśli nikt nie przychodzi przez 15 minut, to uznaję, że nikt nie przyjdzie. Only upon appointment made personally/by Teams/mail. Room no. 346, Chemistry building (central campus), Wednesdays 1:15pm and Thursdays 3:15pm. Other days/hours possible upon contact with me. If no one comes for 15 minutes, consultations can be cancelled.

Wejście z terenu centralnego (od fontanny): Z holu windowego wjechać windą na 3. piętro (lub skorzystać ze schodów z szatni). Na 3. piętrze, wychodząc z windy należy skręcić w lewo, dojść do końca korytarza, wejść na półpiętro i zadzwonić przez domofon do drzwi po prawej (drzwi nr 341): domofon nr 6, ew. jeśli nikt nie odbiera, to 1, 7 lub 10. Po otwarciu drzwi trzeba iść na wprost przez całe laboratorium. 346 to pierwszy pokój po lewej w korytarzu za laboratorium. Entrance from the campus side (fountain): In the elevator hall use elevator to reach 3. floor (or use stairs from the cloakroom entrance). On the 3. floor, when going out of the elevator turn left, go to the end of the corridor and 10 steps up at the end of the corridor. Use intercom on the right at the door number 341. Dial 6, in case nobody picks up you can also try 1, 7 or 10. Behind the doors with intercom go straight through the laboratory. 346 is the first door on the left in the corridor behind the laboratory.
