Organic nitrate aerosol formation via NO3 + biogenic volatile organic compounds in the southeastern United States

Gas- and aerosol-phase measurements of oxidants, biogenic volatile organic compounds (BVOCs) and organic nitrates made during the Southern Oxidant and Aerosol Study (SOAS campaign, Summer 2013) in central Alabama show that a nitrate radical (NO3) reaction ...

Spherical superstructures of oxide nanoparticles for catalytic reactions in microchemical reactors

Martinus Gijs, Virendra Kumar Parashar, Josias Basil Wacker

We report the fabrication of spherical superstructures composed of SiO2 and TiO2 nanoparticles and their applications in catalyzing organic reactions. Assembling of the nanoparticles into superstructures is done by heating a water-in-oil micro-emulsion, wh ...

Comprehensive kinetic model for the dissolution, reaction and crystallization processes involved in the synthesis of aspirin

Julien Léo Billeter

Kinetic modeling of batch reactions monitored by in-situ spectroscopy has been shown to be a helpful method for developing a complete understanding of reaction systems. Much work has been done to demonstrate the ability to model dissolution, reaction and c ...

UV-Cured Cellulose Nanofiber Composites with Moisture Durable Oxygen Barrier Properties

Yves Leterrier, John Christopher Plummer, Tommaso Nardi, Sylvain Cyril Claude Galland, Lars Berglund

Nanocomposites based on 10 to 60 vol % cellulose nanofibers (NFC) in a photopolymerizable hyperbranched acrylate matrix were prepared. Unmodified NFC and NFC chemically modified with a silane coupling agent and with ceric ammonium nitrate for direct polyme ...

Insight into the decomposition pathway of the complex hydride Al3Li4(BH4)(13)

Elsa Callini

The decomposition pathway of the complex hydride Al3Li 4(BH4)13 is in the focus of this study. Initially the compound attracted great interest due to its high H2 capacity (17.2 wt.%) and desorption at moderate temperatures (<100 °C). This work sheds lig ...

Bimetallic Oxidative Addition Involving Radical Intermediates in Nickel-Catalyzed Alkyl-Alkyl Kumada Coupling Reactions

Xile Hu, Matthew Wodrich, Jan Breitenfeld, Jesus Ruiz

Many nickel-based catalysts have been reported for cross-coupling reactions of nonactivated alkyl halides. The mechanistic understanding of these reactions is still primitive. Here we report a mechanistic study of alkyl-alkyl Kumada coupling catalyzed by a ...

Mechanistic Studies Related to Nickel-Catalyzed Alkyl-Alkyl Cross Coupling Reactions

Jan Breitenfeld

Cross-coupling reactions of non-activated alkyl halides are potentially useful chemical transformations. At the same time, however, they are challenging due to a series of unproductive side reactions. Recently, significant progress has been made to overcom ...

Influence of Halogen Atoms on a Homologous Series of Bis-Cyclometalated Iridium(III) Complexes

Mohammad Khaja Nazeeruddin, Rosario Scopelliti, Ursula Röthlisberger, Ivano Tavernelli, Basile Curchod, Frédéric Steimer

A series of homologous bis-cyclometalated iridium(III) complexes Ir(2,4-di-X-phenyl-pyridine)2(picolinate) (X = H, F, Cl, Br) HIrPic, FIrPic, ClIrPic, and BrIrPic has been synthesized and characterized by NMR, X-ray crystallography, UV–vis absorption and e ...

Synthesis, Reactivity, and Catalytic Application of a Nickel Pincer Hydride Complex

Rosario Scopelliti, Xile Hu, Jan Breitenfeld

The nickel(II) hydride complex [(MeN2N)Ni-H] (2) was synthesized by the reaction of [(MeN2N)Ni-OMe] (6) with Ph2SiH2 and was characterized by NMR and IR spectroscopy as well as X-ray crystallography. 2 was unstable in solution, and it decomposed via two re ...

UV radiation induces genome-mediated, site-specific cleavage in viral protein

Tamar Kohn, Yury Tsybin, Laure Menin, Krista Rule Wigginton, Michele Cascella, Hisham Ben Hamidane, Anne Thérèse Sigstam

Much research has been dedicated to understanding the molecular basis of UV damage to biomolecules, yet many questions remain regarding the specific pathways involved. Here we describe a genome-mediated mechanism that causes sitespecific virus protein clea ...
