The adsorption of methamphetamine on Ag nanoparticles dispersed in agarose gel – Detection of methamphetamine in fingerprints by SERS

Autor: Luciano P. Silva, Marco Antonio de Souza, Flavia C. C. Oliveira, Joel C. Rubim, Karolyne V. de Oliveira

Publikováno v: Vibrational Spectroscopy. 98:152-157

Surface-enhanced Raman scattering (SERS) has been used to investigate the adsorption of methamphetamine hydrochloride (MA) on AgNPs surfaces characterized by the dispersion of AgNPs on agarose gel (AgNPs/Agar). The AgNPs/Agar was characterized by tra

Process development for cigarette butts recycling into cellulose pulp

Autor: Loureine Raposo Garcez, Marco Antônio Duarte, Paulo A. Z. Suarez, Thérèse Hofmann Gatti, Maria Betânia d’Heni Teixeira, Joel C. Rubim

Publikováno v: Waste Management. 60:140-150

Cigarette butts, which are usually thrown on the ground or into ordinary bins, have been recognized as toxic residues since may contain cigarette contaminants and chemicals produced during combustion. Therefore, contaminants in cigarette butts can be

Surface-enhanced Raman spectroscopy of molecules adsorbed on silver nanoparticles dispersed an agarose gel and their adsorption isotherms

Autor: Karolyne V. de Oliveira, Joel C. Rubim

Publikováno v: Vibrational Spectroscopy. 86:290-301

Surface-enhanced Raman scattering (SERS) was used to obtain adsorption isotherms for two types of SERS-active substrates: silver nanoparticles (AgNPs) dispersed in water (AgNP/sol); and AgNPs dispersed in agarose gel (AgNP/Agar). Rodhamine 6G (R6G) w

The electrochemical reduction of CO2 on a copper electrode in 1-n -butyl-3-methyl imidazolium tetrafluoroborate (BMI.BF4 ) monitored by surface-enhanced Raman scattering (SERS)

Autor: Isabela R. Leite, Vianney O. Santos, Alexandre G. Brolo, Joel C. Rubim

Publikováno v: Journal of Raman Spectroscopy. 47:674-680

The electrochemical conversion of CO2 into value-added products using room temperature ionic liquids as solvent/electrolyte has been proposed as an alternative to minimize the environmental effects of CO2 emissions. A key issue in the design of elect
