Pectin-decorated magnetite nanoparticles as both iron delivery systems and protective matrices for probiotic bacteria
(Elsevier Science, 2019-08)
The goal of this work was to investigate biophysical stability of iron-pectin nanoparticles and analyze the feasibility of using them as delivery systems for the probiotic strain Lactobacillus plantarum CIDCA 83114. Iron ...
Synthesis of a zinc–imidazole metal–organic framework (ZIF-8) using ZnO rods grown on cotton fabrics as precursors: arsenate absorption studies
(Springer, 2020-05)
A Zn-imidazolate metal–organic framework, ZIF-8, was synthesized using ZnO nanorods grown on cotton fibers as precursors. We monitored the synthesis path via X-ray diffraction, scanning electron microscopy, and thermogravimetric ...

The literature describes experiments in which the ceria nanoparticles significantly improved the bioactive glass mensenquimais differentiation of stem cells into osteoblasts and increased production of collagen (extracellular ...
Nanofibras de carbono verticalmente alinhadas: estudo do crescimento por microscopia eletrônica de transmissão
(Universidade Federal de Minas GeraisUFMG, 2008-08-22)
This work is about the growth of vertically aligned Carbon Nanofibers -CNFs - grown by Plasma Enhanced Chemical Vapour Deposition - PECVD. Being so, a detailed study of catalyst particle is necessary and Transmission ...
Electronic structure, growth mechanism, and sonophotocatalytic properties of sphere-like self-assembled NiWO4 nanocrystals
(Elsevier B.V., 2018-12-01)
In this communications, we report the synthesis of nickel tungstate (NiWO4) nanocrystals by controlled co-precipitation at 95 degrees C for 2 h, followed by heat treatment at 600 degrees C for 2 h. The structure of the ...
Zn1-xMgxO nanoparticles prepared by the polymeric precursor method: Correlation between photoluminescence and local structure
(2018-12-01)
ZnO is an n-type semiconductor having a wide band gap which has been studied as green phosphors because of its luminescence properties, although the centers and mechanisms responsible for its luminescence are still a matter ...
Growth and vacuum post-annealing effect on the structural, electrical and optical properties of Sn-doped In2O3 thin films
(Elsevier B.V., 2020-09-01)
Nowadays, the fabrication of cheaper, thermodynamically stable and durable transparent semiconducting oxide-based thin films are on high demand to enhance the properties of optoelectronic, sensing and energy harvesting ...
Processamento de dados sísmicos marinhos de alta resolução usando sistema sparker monocanal: (plataforma da Bahia, Brasil)
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM GEODINÂMICA E GEOFÍSICA, 2021-04-20)
Single-channel seismic data are still a challenge to apply fundamental processing
techniques such as deconvolution and migration. This study proposes a workflow
processing for high-resolution seismic-reflection data regarding ...
Porous cordierite-based ceramics processed by starch consolidation casting – Microstructure and high-temperature mechanical behavior
(Elsevier, 2018-03)
Porous cordierite-based ceramics with different microstructural features and mechanical behavior were formed by starch consolidation casting (SCC) using native potato and corn starches and sintered at 1275, 1300 and 1330 ...
