Journal ArticleDOI
The role of Pd nanoparticles in ionic liquid in the Heck reaction.
TL;DR: Results strongly suggest that the Pd(0) nanoparticles serve as a reservoir of "homogeneous" catalytic active species.
Journal ArticleDOI
Nanoscale Pt(0) particles prepared in imidazolium room temperature ionic liquids: synthesis from an organometallic precursor, characterization, and catalytic properties in hydrogenation reactions.
Carla W. Scheeren,Giovanna Machado,Jairton Dupont,Paulo Fernando Papaleo Fichtner,Sérgio Ribeiro Texeira +4 more
TL;DR: The reaction of Pt(2)(dba)(3) dispersed in room temperature 1-n-butyl-3-methylimidazolium (BMI) hexafluorophosphate ionic liquid with molecular hydrogen leads to stable and isolable nanometric Pt(0) particles.
Journal ArticleDOI
Staphylococcus aureus and Staphylococcus epidermidis infections on implants.
Weslley Felix de Oliveira,Priscila Marcelino dos Santos Silva,Rayane C.S. Silva,Germana M.M. Silva,Giovanna Machado,Luana Cassandra Breitenbach Barroso Coelho,Maria Tereza dos Santos Correia +6 more
TL;DR: It is discussed some methodologies used in the search for new compounds with antibiofilm activity and the main strategies for biomaterial surface modifications to avoid bacterial plaque formation and consequent infection, and some approaches used as a way to avoid the spread of bacterial resistance to antimicrobials.
Journal ArticleDOI
The partial hydrogenation of benzene to cyclohexene by nanoscale ruthenium catalysts in imidazolium ionic liquids.
Edson T. Silveira,Alexandre P. Umpierre,Liane M. Rossi,Giovanna Machado,Jonder Morais,Gabriel Vieira Soares,Israel Jacob Rabin Baumvol,Sérgio R. Teixeira,Paulo Fernando Papaleo Fichtner,Jairton Dupont +9 more
TL;DR: The controlled decomposition of an Ru(0) organometallic precursor dispersed in 1-n-butyl-3-methylimidazolium hexafluorophosphate (BMI.PF(6), which represents a rare example of partial hydrogenation of benzene by soluble transition-metal nanoparticles, is controlled.
Journal ArticleDOI
Synthesis and Characterization of Pt(0) Nanoparticles in Imidazolium Ionic Liquids
Carla W. Scheeren,Giovanna Machado,Sérgio R. Teixeira,Jonder Morais,and Josiel B. Domingos,Jairton Dupont +5 more
TL;DR: In this article, a controlled decomposition of Pt2(dba)3 (dba = dibenzylideneacetone) dispersed in 1-n-butyl-3-methylimidazolium tetrafluoroborate (BMI.BF4) and hexafluorophosphate (bMI.PF6) ionic liquids in the presence of cyclohexene by molecular hydrogen produces Pt(0) nanoparticles.
