IQCC Forum: Autumn edition 2021

Yesterday took place the Autumn edition of the IQCC Forum, a quarterly meeting-place where high-quality science is discussed. The IQCC Forum gives the opportunity for PhD and postdoc members of the IQCC to present their work to a select group of critical researchers, enhancing intra-IQCC collaborations and promoting knowledge exchange within the institute. This will

A shared mechanistic pathway for pyridoxal phosphate–dependent arginine oxidases

Dr. Marc Garcia-Borràs (IQCC) is part of an international multidisciplinary research team led by Prof. Katherine Ryan (University of British Columbia, Canada) that has recently published a new study in PNAS entitled “A shared mechanistic pathway for pyridoxal phosphate–dependent arginine oxidases”. Pyridoxal phosphate (PLP)-dependent enzymes rarely react with oxygen, but an emerging group of PLP-

Cover ChemEurJ on mechanistic aspects of the Pd-catalyzed Suzuki-Miyaura cross-coupling reaction

The journal Chemistry-A European Journal included in the Hot Topic on C-C coupling the recently published review “Mechanistic Aspects of the Palladium-Catalyzed Suzuki-Miyaura Cross-Coupling Reaction”. Among the different reactions that lead to the formation of C-C bonds, the Suzuki-Miyaura approach has a fundamental role, at the level of basic research and industrial applications. In particular, the palladium

European Researchers’ Night 2021 at IQCC

Every year in September since 2008, the IQCC is organizing together with the Scientific Culture and Digital Communication (C4D) unit of the UdG, the Diputació de Girona and the Girona City Council the European Researchers’ Night with the aim to bring science closer to the Girona general public. The European Researchers’ Night is a coordianted

Cover CatSciTech on substrate oxyfunctionalizations

The journal Catalysis Science & Technology features on its front cover the recently published research article “Simultaneous screening of multiple substrates with an unspecific peroxygenase enabled modified alkane and alkene oxyfunctionalisations”, a collaboration between the research teams of Jun.-Prof. Martin Weissenborn (Leibniz Institute of Plant Biochemistry, Halle (Saale)) and Dr. Marc Garcia-Borràs. In this project,

IQCC Challenges – Live talks

The IQCC is starting a new series of online talks to address challenges in the research fields where the IQCC is playing a role, through the investigations of one of the Principal Investigators. An external expert is invited to give a seminar, together with one of the junior researchers of the IQCC. These complementary views will highlight

Sergi Ruiz-Barragan, new postdoc at IQCC

Dr. Sergi Ruiz-Barragan has recently become a new member of the Institute of Computational Chemistry and Catalysis (IQCC). Dr. Ruiz-Barragan did his PhD at the IQCC/University of Girona on modelling of potential energy surfaces for photochemistry: conical intersections and application to optical control under the supervision of Dr. Lluís Blancafort in 2014. He has postdocotral

The Unexplored Importance of Fleeting Chiral Intermediates in Enzyme-catalyzed Reactions

Decades of extensive research efforts by biochemists, organic chemists and protein engineers have led to an understanding of the basic mechanisms of essentially all known types of enzymes, but in a formidable number of cases an essential aspect has been overlooked. The occurrence of short-lived chiral intermediates formed by symmetry-breaking of prochiral precursors in enzyme

Unexpected Disparity in Photoinduced Reactions of C60 and C70 in Water with the Generation of superoxide or singlet-oxygen

Well-defined fullerene-PEG conjugates, C60-PEG (1) and two C70-PEG (2 and 3 with the addition sites on ab-[6,6] and cc-[6,6]-junctions), were prepared from their corresponding Prato monoadduct precursors. The resulting highly water-soluble fullerene-PEG conjugates 1–3 were evaluated for their DNA-cleaving activities and reactive oxygen species (ROS) generation under visible light irradiation. Unexpectedly, photoinduced cleavage of DNA by C60-PEG 1 was much higher than that by

Cover JMaterChemC on photo-induced electron transfer in mechanically interlocked suit[3]ane systems

The journal Journal of Materials Chemistry C features on its front cover the recently published paper “Photoinduced electron transfer in mechanically interlocked suit[3]ane systems”. Suitanes, a new class of two-component mechanically interlocked systems, have recently been developed. In this work, we report a detailed study of photoinduced electron-transfer processes in suit[3]anes consisting of a 3-fold
