FACING THE FUTURE WITH OPTIMISM

he paint is peeling off the walls, the stair steps are visibly worn from 50 years of students scurrying to classes, and an old-fashioned padlock and chain secures the gate to the faculty parking lot. Welcome to the Department of Chemistry at the University of Warsaw, one of the best research chemistry departments in Poland and a historically important place for analytical chemistry. It was here where Wiktor Kemula and his student Zenon Kublik developed the hanging drop mercury electrode in the late 1950s that helped launch modern electroanalytical chemistry (D

picting Poland's most famous chemist, Maria Sklodowska Curie.) To appreciate how far the University ol Warsaw has come, it is important to understand its past. The university emerged from the dark days of World War II with many of its students and faculty dead or gone and an estimated 70% of its buildings destroyed. The small, old central university campus was rebuilt. The chemistry building, which was completed in 1939, was outside the campus and survived the war. Because the government made no effort to create a single new campus (possibly for political reasons or to prevent student criticism) chemistry and many other sciences are today spread over Warsaw and located several kilometers from flie central campus

By the 1970s Poland had developed into a somewhat more open society than

many other communist-led countries. Western journals were common and scientists were allowed to travel and work with western scientists, although the process for getting exit visas was not easy. "I never knew until the last moment whether I could leave," says Stojek. Simple correspondence was also difficult. "It took six weeks to get a letter to the U.S.," recalls Stojek. "I was embarrassed." The slow mail deliveries "killed collaborations" and were a barrier to publishing in western journals. Osteryoung agrees: "It was hard to keep the collaboration going back and forth." Despite the obstacles, Stojek managed several trips to the United States and even brought his family with him. He also published extensively in English language journals and authored 31 articles in international journals from 1976 to 1989. Stojek

credits his "informal" ties with western researchers as one of the keys to his publishing success. Adequate research instrumentation proved to be another problem. Buying western equipment was virtually impossible because the Polish currency, the zloty, was not convertible into western currency. However, there were eastern block instruments. "There were lots of bright ideas in terms of instruments, potentially even better than western instruments " says Stojek. "However, you couldn't repair them the parts weren't of high quality and breakdowns were very often " In the early eighties remembers Stojek he had 10 potentiostats but only four or five were working at one time "Now we have four PAR [Princeton Aoolied Research ] potentiostats We don't need any more They work well"

Focus Communications, too, have improved. Not only is there E-mail, but Warsaw has a special post office that takes air mail letters directly to the airport to expedite delivery. Foreign travel is encouraged, although funding is limited. A few students have even recently come from the west to study and conduct research at Warsaw. "They appreciate our work," says University of Warsaw analytical chemist Adam Hulanicki.

tem is judged, in part, by the number of publications by a researcher multiplied by a journal's citation impact. Thus, publications in western journals such as Analytical Chemistry are highly prized.
