Solução tampão que mimetiza as características ácido-base do tampão SMP em resposta à acidez de solos brasileiros
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Ciência do Solo, 2011-02-21)
In Brazil, the SMP buffer has been used since the 60's as the main method to estimate
the potential acidity and/or the soil lime requirement. However, SMP contains pnitrophenol
and potassium chromate, substances with high ...
Sensor for hydrogen peroxide based on Prussian Blue modified electrode: Improvement of the operational stability
(2000-09-13)
Improvement of the operational stability of amperometric sensors based on Prussian Blue (PB) modified glassy carbon electrodes is presented. The long term performance of the sensors was evaluated by injection of hydrogen ...

Determination of electrochemical parameters and corrosion rate for carbon steel in un-buffered sodium chloride solutions using a superposition model
(2007)
Corrosion of carbon steel in un-buffered NaCl solutions was studied applying linear potential sweep technique to a rotating disk electrode. Current-potential curves were obtained from linear potential sweep at a rate of 1 ...
GABA released from cultured cortical neurons influences the modulation of t-[35S]butylbicyclophosphorothionate binding at the GABAA receptor: Effects of thymol
(Elsevier Science, 2008-12)
Thymol is a monoterpene that specifically interacts with synaptic neural functions in neuronal GABA-operated Cl- channels. Here we explore the effects of thymol, and propofol as positive control, on t-[35S]butylbicycloph ...
