Expanded use of a fast photography technique to characterize laser-induced plasma plumes
(2014-06)
"Expanded use of fast photography is proposed to characterize laser ablation plasma plumes by the analysis of a set of photographs by means of appropriate mathematical algorithms. The laser ablation plasma plumes studied ...
Electron transport study on functionalized armchair graphene nanoribbons: DFT calculations
(2016)
"Quantum transport studies are performed on doped and functionalized 8- and 11-armchair graphene nanoribbons (aGNRs) by means of density functional theory. Substitutional doping is performed by introducing boron, nitrogen, ...
The role of silver nanoparticles functionalized on TiO2 for photocatalytic disinfection of harmful algae
(2015)
"Silver loaded TiO2 samples were prepared by photodeposition of different amounts of Ag+ ions over commercial titanium dioxide (Evonik TiO2 P25) in aqueous media without the presence of sacrificial agents. The obtained ...
Microstructure and magnetocaloric effect of melt-spun Ni52Mn26Ga22 ribbon
(2012-04)
"Microstructural features and magnetocaloric properties of Ni52Mn26Ga22 melt-spun ribbons were studied. Results show that there are four types of differently oriented variants of seven-layered modulated (7M) martensite at ...
Effective photoreduction of a nitroaromatic environmental endocrine disruptor by AgNPs functionalized on nanocrystalline TiO2
(2015)
"Unprecedented photoactivity of silver nanoparticles photodeposited on nanocrystalline TiO2 for the efficient reduction of 4-nitrophenol at room temperature is reported. The use of Na2SO3 as a harmless scavenger agent for ...
Improvement and analysis of a pseudo random bit generator by means of cellular automata
(2010)
"In this paper, we implement a revised pseudo random bit generator based on a rule-90 cellular automaton. For this purpose, we introduce a sequence matrix HN with the aim of calculating the pseudo random sequences of N ...
A simple circuit with dynamic logic architecture of basic logic gates
(2010)
"We report experimental results obtained with a circuit possessing dynamic logic architecture based on one of the theoretical schemes proposed by H. Peng and collaborators in 2008. The schematic diagram of the electronic ...
Matrix approach of an encryption system based on cellular automata and its numerical implementation
(2012)
"The main components of an encryption system based on rule 90 cellular automata, i.e., two indexed families of permutations and a pseudorandom bit generator are implemented in a very xible way through a convenient matrix ...
Including transcription factor information in the superparamagnetic clustering of microarray data
(2010)
"In this work, we modify the superparamagnetic clustering algorithm (SPC) by adding an extra weight to the interaction formula that considers which genes are regulated by the same transcription factor. With this modified ...
Multifractal analyses of row sum signals of elementary cellular automata
(2012)
"We first apply the WT-MFDFA, MFDFA, and WTMM multifractal methods to binomial multifrac-tal time series of three different binomial parameters and find that the WTMM method indicates an enhanced difference between the fractal ...
