1. Estudo do mecanismo eletroforético de coleta na filtração de aerossóis.
Previous works have shown that the presence of electrostatic forces in particles significantly affect the performance of a filter, both increasing collection efficiency and reducing pressure drop. Recently, in the Environmental Control research group of the Chemical Engineering Department of UFSCar, Rodrigues (2005) have studied the filtration of electric ch

2. Like-charge attraction between polyelectrolytes induced by counterion charge density waves
Electrostatics in aqueous media is commonly understood in terms of screened Coulomb interactions, where like-charged objects, such as polyelectrolytes, always repel. These intuitive expectations are based on mean field theories, such as the Poisson–Boltzmann formalism, which are routinely used in colloid science and computational biology [Israelachvili

3. Do conformational biases of simple helical junctions influence RNA folding stability and specificity?
Structured RNAs must fold into their native structures and discriminate against a large number of alternative ones, an especially difficult task given the limited information content of RNA's nucleotide alphabet. The simplest motifs within structured RNAs are two helices joined by nonhelical junctions. To uncover the fundamental behavior of these motifs and

4. Theory of electrostatic effects in soft biological interfaces using atomic force microscopy.
We calculated the electrostatic force between a planar interface, such as a planar-supported lipid bilayer membrane, and the tip of a stylus on which another lipid bilayer or some other biomacromolecular system might be deposited. We considered styli with rounded tips as well as conical tips. To take into account the effect of dynamical hydrogen-bonded struc
