A molecular dynamics study on glucose molecular recognition by a non-enzymatic selective sensor based on a conducting polymer
Zanuy Gomara, David; Fabregat Jové, Georgina; Ferreira, Carlos Arthur; Alemán Llansó, Carlos (Royal Society of Chemistry (RSC), 2019-01-01)
Article
Open AccessPoly(hydroxymethyl-3,4-ethylendioxythiophene) (PHMeDOT), a very electroactive polythiophene derivative bearing a dioxane ring fused onto the thiophene ring and an exocyclic hydroxymethyl substituent, is able to electrocatalyze ... -
Antifouling properties of papain-based antifouling coatings
Peres, Rafael; Armelín Diggroc, Elaine Aparecida; Moreno Martinez, Juan Antonio; Alemán Llansó, Carlos; Ferreira, Carlos Arthur (2015-06-30)
Article
Open AccessThe aim of this work is to study the antifouling performance and water uptake behaviour of coatings formulated with papain (an environmentally friendly pigment). Antifouling coatings have been formulated using rosin (natural ... -
Influence of pH in the synthesis of ferric tannate pigment for application in antifouling coatings
Peres, Rafael; Zmozinski, Ariane V.; Moreno Martinez, Juan Antonio; Armelín Diggroc, Elaine Aparecida; Alemán Llansó, Carlos; Ferreira, Carlos Arthur (2017-05-08)
Article
Open AccessFerric tannate was synthesized at pH 4 and pH 7 (FT4 and FT7, respectively) as a new class of environmentally friendly antifouling pigments. The solubility of both pigments was evaluated by gravimetric tests, showing that ... -
Modified tannin extracted from black wattle tree as an environmentally friendly antifouling pigment
Peres, Rafael; Armelín Diggroc, Elaine Aparecida; Alemán Llansó, Carlos; Ferreira, Carlos Arthur (2015-03-01)
Article
Open AccessThe use of modified black wattle tannin as an antifouling pigment is reported in this work. A mixture of tannin adsorbed in activated carbon (soluble fraction of tannin) and low soluble fraction of tannin was used as an ... -
Nanometric polythiophene films with electrocatalytic activity for non-enzymatic detection of glucose
Hocevar, Marcele A.; Fabregat Jové, Georgina; Armelín Diggroc, Elaine Aparecida; Ferreira, Carlos Arthur; Alemán Llansó, Carlos (2016-06-01)
Article
Open AccessElectrochemical detection of glucose using simple polymeric electrodes without the assistance of enzymatic or inorganic catalysts (i.e. metals or metal oxides) has been issued a challenge to the scientific community. In ... -
Smart paint for anodic protection of steel
Silva, Rodrigo Sanchonete; Alemán Llansó, Carlos; Ferreira, Carlos Arthur; Armelín Diggroc, Elaine Aparecida; Ferreira, Jane Zoppas; Meneguzzi, Alvaro (2015-01-01)
Article
Open AccessIn order to overcome the difficulties associated to the solubility and mechanical integrity of polyaniline (PAni) films, in this work we develop a binder by mixing PAni in the oxidized and undoped state (emeraldine base ... -
The influence of organophosphonic acid and conducting polymer on the adhesion and protection of epoxy coating on aluminium alloy
Dalmoro, Viviane; Alemán Llansó, Carlos; Ferreira, Carlos Arthur; Dos Santos, J.H.Z.; Azambuja, Denise S.; Armelín Diggroc, Elaine Aparecida (2015-11-01)
Article
Open AccessIn the present study we compared the beneficial effect on the incorporation of modified silane nanocoating and conducting polymer additive to the adhesion and protection of aluminium surface with epoxy coating. Results ...
