H. Passos has published 57 scientific articles, including 4 critical reviews: 2 on Green Chem journal (IF 11.03) [1 classified as a Highly Cited Paper, Web of Science], 1 on Crit Rev Environ Sci Technol journal (IF 11.75), and 1 on Curr Opin Green Sustain Chem (IF 8.84). All 57 articles were published in JCR SCI journals, counting with +1950 citations and an h-index of 24 ( Scopus on Apryl 2024). She has published in several high IF journals, namely Angew Chem Int Ed (IF 16.82), Chem Eng J (IF 16.74), Green Chem (IF 11.03), ACS Sustain Chem Eng (IF 9.22) and Sep Purif Technol (IF 9.14), with an average journal IF of 7.95. She is the first author in 16 papers, corresponding author in 7, and worked with +130 different co-authors with diverse affiliations and internationally recognized as leading scientists in green solvents field, namely H. Ohno (Japan), R.D. Rogers (United States), I. Billard (France) and J.A.P. Coutinho (Portugal). Moreover, she has contributed with +150 oral and posters communications and 2 plenary/invited lectures in national and international conferences. H. Passos supervise(d) 1 post-doctoral researcher, 3 PhD, 10 MCs (3 international) and 9 BCs students. H. Passos was PI of one international Bilateral Cooperation with France and Co-PI of another with Brazil. Currently she is the PI of one FCT R&D project, PlatILPlus, aiming the recycling and recovery of platinum group metals and rare earth elements from spent automotive catalytic converters. H. Passos was guest editor of one special issue and is reviewer on several multidisciplinary journals.
