Retaining the specific capacitance under electrochemical stress: A pH-induced s...
Alves, Aila Cossovan; Chiavassa, Luísa; Martins, Tiago D.; Taryba, Maryna; Baleizão, Carlos; Moura e Silva, Teresa; MONTEMOR, FATIMAIn this study, we report the enhanced electrochemical performance of a MnO2 electrode modified with a pH-sensitive co-polymer, activated at acidic pH, and designed to counteract MnO2 degradation in aqueous aqueous pseudocapacitors. The conformation of this polymer is controlled by the local pH changes that occur at the electrode/electrolyte interface during electrochemical stress associated to oxygen evolution....
Mapeamento de processos erosivos e deposicionais utilizando modelagem matemátic...
Daniel, Evandro; Vieira, Bianca Carvalho; Martins, Tiago D.; Bateira, Carlos; Bonini, José EduardoMathematical models have the potential to estimate and identify prone areas to erosional processes. SIMWE (Simulated Water Erosion) model considers hydrological and soil properties, simulates erosion, transport, and deposition by surface flow. This research aimed to evaluate the dynamics of erosion and deposition rates through the application of the SIMWE in the Alto Espraiado basin, São Pedro (SP), which prese...
Reversible imine crosslinking in waterborne self-healing polymer coatings
Martins, Tiago D.; Viciosa, M. Teresa; Oliveira, Mariana B.; Fernandes, Auguste; Mano, João F.; Baleizão, Carlos; Farinha, José Paulo S.Waterborne polymer coatings have the potential to address the environmental concerns associated with solvent based systems. To improve their performance without using volatile organic compounds, we propose a new approach based on reconfigurable covalent crosslinking that provides mechanical resistance and self-healing properties. The new waterborne polymer coatings are based on mixtures of aldehyde- and amine-f...
Biotinylated polymer-ruthenium conjugates: in vitro and in vivo studies in a tr...
Côrte-Real, Leonor; Brás, Ana Rita; Pilon, Adhan; Mendes, Nuno Miguel Morais; Ribeiro, Ana Sofia; Martins, Tiago D.; Farinha, José Paulo S.The need for new therapeutic approaches for triple-negative breast cancer is a clinically relevant problem that needs to be solved. Using a multi-targeting approach to enhance cancer cell uptake, we synthesized a new family of ruthenium(II) organometallic complexes envisaging simultaneous active and passive targeting, using biotin and polylactide (PLA), respectively. All compounds with the general formula, [Ru(...
Escorregamentos rasos em São Luiz do Paraitinga (SP, Brasil) (2009-2010)
Bonini, José Eduardo; Sanches Ross, Jurandyr Luciano; Martins, Tiago D.; Vieira, Bianca CarvalhoEscorregamentos e inundações estão entre as tipologias de desastres que geram os maiores danos no Brasil. No verão de 2009-2010 algumas cidades no Planalto de Paraitinga-Paraibuna (SP), dentre elas São Luiz do Paraitinga, foram atingidas por precipitações intensas que deflagraram centenas de escorregamentos e uma grande inundação. O objetivo deste artigo foi caracterizar as áreas afetadas por escorregamentos co...

Red and near-infrared absorbing dicyanomethylene squaraine cyanine dyes: photop...
Martins, Tiago D.; Lima, Eurico; Boto, Renato E.; Ferreira, Diana Sara Pereira; Fernandes, José R.; Almeida, Paulo; Ferreira, Luis F. V.Photodynamic therapy is a medical modality developed for the treatment of several diseases of oncological and non-oncological etiology that requires the presence of a photosensitizer, light and molecular oxygen, which combined will trigger physicochemical reactions responsible for reactive oxygen species production. Given the scarcity of photosensitizers that exhibit desirable characteristics for its potential ...
Avaliação da suscetibilidade a escorregamentos rasos com base na aplicação de e...
Dias, Helen Cristina; Bateira, Carlos; Pissato, Edilson; Martins, Tiago D.; Vieira, Bianca CarvalhoThe aim of this paper was to define the shallowlandslides susceptibility on Caraguatatuba county, based onstatistical analysis of morphological parameters. Theproduction of morphological maps of curvature, aspect,hypsometry and slope were based on SRTM 30 m. From this,it was made a bivariate statistical analysis based oninformative value. Such index it is responsible to relatemorphological classes and shallow l...
Análise dos parâmetros morfológicos de escorregamentos rasos na Serra do Mar, P...
Martins, Tiago D.; Oka-Fiori, Chisato; Vieira, Bianca Carvalho; Correa, Antonio Carlos de Barros; Bateira, CarlosO mapeamento das cicatrizes de escorregamentos é uma importante ferramenta para compreender a espacialização e os fatores condicionantes destesprocessos, permitindo avaliar as principais características do relevo associadas à sua deflagração. O objetivo deste trabalho, portanto, foi realizar uma análise morfológica a partir do mapa de cicatrizes para duas bacias hidrográficas no município de Antonina (PR), afet...
