Foram preparadas mantas de nanofibras eletrofiadas, compostas por poli(ε-caprolactona) (PCL) e diferentes concentrações extrato própolis marrom, com o objetivo desenvolver biomateriais potencial atividade bioativa. As amostras produzidas foram submetidas à análise morfológica meio microscopia eletrônica varredura (MEV), a qual revelou que as fibras apresentavam continuidade, homogeneidade ausência formação gotas. Observou-se uma redução significativa no diâmetro médio das conforme...
Abstract Natural rubber ( NR ) microfibers were obtained from NR/chloroform solutions with or without vulcanization agents, by a solution blow spinning SBS technique. The showed ribbon‐like morphology average widths ranging 15 to 45 μm, depending on the processing conditions. Concentrations of 3%, 4%, and 5% (wt/vol) /chloroform compared; at 4% wt/vol process was most stable, fiber width homogeneous. Microfibrous membranes incorporating vulcanizing agents treated temperatures 70, 80, 90°C...
Among the many methods developed for synthesis of titanium dioxide, cathodic electrosynthesis has not received much attention because resulting amorphous oxy‐hydroxide matrix demands a further thermal annealing step to be transformed into crystalline titania. However, possibility filling deep recessed templates by control solid–liquid interface makes it potentially suitable technique fabrication porous scaffolds photovoltaics and photocatalysis. Furthermore, careful crystallization process...
Abstract With its ability to purify water and treat wastewater, photocatalytic membranes have become a promising solution. The membrane's unique properties allow for the separation of solid compounds degradation organic materials through antibacterial means. Poly(vinylidene fluoride)/titanium oxide (PVDF/TiO 2 ) composite remain choice making these due their economy, effectiveness, safety, durability. In this work membrane reactor (PMR) system was developed using PVDF/TiO fabricated by...
The preparation of mesoscopic states radiation and matter fields through atom-field interactions has been achieved in recent years employed for a range striking applications quantum optics. Here we present technique the control cavity mode which, addition to interacting with two-level atom, is simultaneously submitted linear parametric amplification processes. role amplification-controlling achievement real produce highly squeezed field and, consequently, increase both (i) distance phase...
In this study the incorporation of small contents iron species in polypyrrole was investigated by means magnetization measurements. The performed addition FeCl3 to solution during chemical polymerization with a mass ratio [monomer]/[Fe3+] = 10. Comparison made between pellets and without showed an increase saturation ferromagnetic properties when is present material. This magnetic probably occurs due effective local polarization polymer's polarons.
We demonstrate here for the first time an original and facile approach to preparing titanium oxide (TiO2) tubes using hydrogen peroxide (H2O2) titanyl (IV) oxysulfate (TiOSO4) as sacrificial templates. The method involves dissolving TiOSO4 powder in H2O2 solution subsequently applying thermal treatment on resulting amorphous precipitate. Prepared samples were characterized by X-ray diffraction, scanning electron microscopy (SEM) images, thermogravimetric (TG) analysis, UV-vis analysis....
We present a proposal for the production of longer-lived mesoscopic superpositions which relies on two requirements: parametric amplification and squeezed vacuum reservoir cavity-field states. Our involves interaction two-level atom with cavity field is simultaneously subjected to processes.
Abstract This work proposed a study of in situ polymerization polyaniline (Pani) the presence graphite nanosheets (GNS). The focused on different physical–chemical interactions promoted among them during Pani synthesis using dopants (HCl and DBSA). By means Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X‐ray diffraction (XRD), thermogravimetry (TG/DTG), DC electrical conductivity, demonstrated production nanocomposites with electrical, thermal,...
As propriedades magnéticas de pastilhas prensadas poli (3-hexiltiofeno) (P3HT) parcialmente dopado com o íon foram estudadas na faixa 5 a 300 K, e uma fase ferromagnética foi observada à temperatura ambiente. A origem do momento magnético no P3HT sua interação estão relacionadas formação polarons cadeia polimérica durante processos oxidação/redução.
