Multibody expansion of particle interactions: How many-body is a particular element in a cluster
(2016)
The particle-particle interaction potential of an N-atom cluster is expanded in n-body contributions. The expansion allows us to determine the magnitude of each one of the n-body terms, and consequently quantifies how ...
Encapsulation of Gold Nanostructures and Oil-in-Water Nanocarriers in Microgels with Biomedical Potential
(2018)
Here we report the incorporation of gold nanostructures (nanospheres or nanorods, functionalized with carboxylate-end PEG) and curcumin oil-in-water (O/W) nanoemulsions (CurNem) into alginate microgels using the dripping ...

Effect of rinsing with water immediately after APF gel application on enamel demineralization in situ
(Karger, 2005-01-01)
This double-blind crossover in situ study evaluated the effect of rinsing with water immediately after the application of acidulated phosphate fluoride (APF) on enamel demineralization. APF application was followed by: no ...
Electrochemical studies with copper-based alloys: open-circuit potential oscillations in alkaline media
(Electrochemical Soc Inc., 1993-06-01)
In open-circuit potential measurements of certain Cu-based alloys in NaOH solutions oscillations were observed in Cu-Al and Cu-Ag-Al. Studies with various electrolyte concentrations and rotation speeds of the electrode led ...
Fast Screening for Antioxidant Properties of Flavonoids from Pterogyne nitens Using Electrochemical Methods
(Aoac Int, 2012-05-01)
A fast, low-cost, convenient, and especially sensitive voltammetric screening approach for the study of the antioxidant properties of isoquercitrin and pedalitin from Pterogyne nitens is suggested in this work. These ...
Preparation and bactericidal effect of composites based on crosslinked copolymers containing silver nanoparticles
(Associação Brasileira de Polímeros, 2010-09-01)
Commercial copolymers based on styrene and divinylbenzene containing sulfonic acid groups were used as support for the incorporation of silver nanoparticles. These nanoparticles were obtained in situ by the reduction of ...
Chromosomal characterization of Pseudonannolene strinatii (Spirostreptida, Pseudonannolenidae)
(Fundação Zoobotânica do Rio Grande do Sul, 2004-03-01)
The chromosomes of the cave millipede Pseudonannolene strinatii Mauriès, 1974 were investigated. The diploid chromosome number was found to be 2n=16, XX/XY; the C-banding technique revealed a large amount of heterochromatin ...
Testing the resolving power of two-dimensional K+K+ interferometry
(1998-11-01)
We show results from an analysis performed to test the resolving power of a two-dimensional χ2 method proposed previously when applied to the case of kaon interferometry, where no significant contribution from long-lived ...
