    Vega Martínez, Esther; Lemus, Jesús; Anfruns Bagaria, Alba; González Olmos, Rafael; Palomar, José; Martín, María José (info:eu-re)

    The effect of physical and chemical properties of activated carbon (AC) on the adsorption of ethyl mercaptan, dimethyl sulphide and dimethyl disulphide was investigated by treating a commercial AC with nitric acid and ...

    Laccase-based biosensors for detection of phenolic compounds 

    Rodríguez Delgado, Melissa M.; Alemán Nava, Gibrán S.; Rodríguez Delgado, José Manuel; Dieck-Assad, Graciano; Martínez Chapa, Sergio Omar; Barceló i Cullerés, Damià; Parra, Roberto (2015-12)

    Monitoring of phenolic compounds in the food industry and for environmental and medical applications has become more relevant in recent years. Conventional methods for detection and quantification of these compounds, such ...

    New insights into the influence of activated carbon surface oxygen groups on H2O2 decomposition and oxidation of pre-adsorbed volatile organic compounds 

    Anfruns Bagaria, Alba; García-Suárez, Eduardo J.; Montes Morán, Miguel A.; González Olmos, Rafael; Martín, María José (info:eu-re)

    In this study, the influence of the surface oxygen groups of activated carbons (ACs) on the decomposition of H2O2 and the consequent OH radicals generation is investigated. The oxidation of pre-adsorbed volatile organic ...

    Reductive Coupling of Nitric Oxide by Cu(I): Stepwise Formation of Mono and Dinitrosyl Species en route to a Cupric Hyponitrite Intermediate 

    Bhadra, Mayukh; Albert, Therese; Franke, Alicja; Josef, Verena; Ivanović-Burmazović, Ivana; Swart, Marcel; Moënne-Loccoz, Pierre; Karlin, Kenneth D. (info:eu-re)

    Transition-metal-mediated reductive coupling of nitric oxide (NO(g)) to nitrous oxide (N2O(g)) has significance across the fields of industrial chemistry, biochemistry, medicine, and environmental health. Herein, we elucidate ...

    Tailoring the nonlinear absorption of fluorescent dyes by substitution at a boron center 

    Ośmiałowski, Borys; Petrusevich, Elizaveta F.; Nawrot, Katarzyna C.; Paszkiewicz, Bartłomiej K.; Nyk, Marcin; Zielak-Milewska, Judyta; Jędrzejewska, Beata; Luis Luis, Josep Maria; Jacquemin, Denis; Zaleśny, Robert (info:eu-re)

    The tuning of the spectroscopic signatures of boron-carrying fluorescent dyes is achieved by subtle chemical modifications. In more detail, we propose a new series of compounds incorporating up to three electron-donating ...

    Uptake, translocation and ligand of silver in Lactuca sativa exposed to silver nanoparticles of different size, coatings and concentration
