Publikováno v: Pakiet, M, Kowalczyk, I, Leiva Garcia, R, Moorcroft, R, Nichol, T, Smith, T, Akid, R & Brycki, B 2019, ' Gemini surfactant as multifunctional corrosion and biocorrosion inhibitors for mild steel ', Bioelectrochemistry, vol. 128, pp. 252-262 . https://doi.org/10.1016/j.bioelechem.2019.04.005
Biocorrosion is an important type of corrosion which leads to economic losses across oil and gas industries, due to increased monitoring, maintenance, and a reduction in platform availability. Ideally, a chemical compound engineered to mitigate again

Self-similar roughening of drying wet paper
Autor: Jesús Marquez, Rafael Leiva García, Orlando Susarrey, Didier Samayoa, Alexander S. Balankin, Daniel Morales, José Francisco Martínez Trinidad
Publikováno v: Physical review. E, Statistical, nonlinear, and soft matter physics. 73(6 Pt 2)
We studied the kinetic roughening dynamics of drying wet paper. The configurations of dry paper sheets are found to be self-similar, rater than self-affine. Accordingly, the paper roughening dynamics corresponds to the new class of anomalous kinetic
