Deposition of BiOBr thin films by thermal evaporation and evaluation of its photocatalytic activity
Published 2015“…The analysis by XRD of the thin film deposited confirmed the formation of BiOBr, showing a high degree of specific crystal orientation in {0 0 1} planes. In the same way, SEM analysis showed that the deposition of oxide took place by formation of plates and small particles with shape of flowers. …”

Biocompatibility and surface characteristics of resin-modified glass ionomer cements with ammonium quaternary compounds or silver nanoparticles: an in vitroStudy
Published 2018“…All the experimental groups increase or decrease statistically significantly the VHN (P < 0 05) compared with the control group, except for GC Fuji PLUS added with hexadecyltrimethylammonium bromide 1 wt%. In the same way, all groups show a statistically significant (P < 0 05) increase or decrease in Ra compared with the control group except for GC Fuji ORTHO added with benzalkonium chloride 2 wt%, GC Fuji PLUS added with benzalkonium chloride 2 wt%, and GC Fuji PLUS added with cetylpyridinium chloride 2 wt%. …”

Molecular dynamics of free and graphite-supported Pt-Pd nanoparticles
Published 2013“…The melting transition temperature was found to increase when the particle is on the graphite support, with an increase at least 180 K higher than that of the same-sized free nanoparticle. The results of the density distributions perpendicular to the surface indicate that the Pd atoms have a tendency to remain at the surface, and the Pd atoms wet the graphite surface more than the Pt atoms, while root mean squares suggest that surface melting starts from the cluster surface, and surface melting was seen in both free and graphite-supported nanoparticles. …”

One-Step Green Synthesis of Metallic Nanoparticles Using Sodium Alginate
Published 2016“…Currently, traditional physical and chemical methods can synthesize these nanoparticles but their disadvantages such as costs, time, effectiveness, and toxicity of precursors provide a wide range of problems for the synthesis of these nanoparticles. Recently, some natural polymers and organic compounds have been used for the synthesis of nanoparticles by green methods. …”

Synthesis and characterization of metal nanoparticles by pulsed laser ablation in liquid media (PLAL)
Published 2015“…In this thesis we report an easy, fast, alternative-novel and one-step method for the preparation of pure and stable (in some cases) noble metal nanoparticles, viz Pulsed Laser Ablation in liquid media; this method presents significant advantages over chemical routes as: pure metal nanoparticles production, less aggregation, non-vacuum requirements, non-toxic agents are required, size and shape tunability, between others. …”
