This work describes a liquid allantoin-enriched pectin hydrogel with hydrophilic behavior that is supported by the presence of functional groups related to healing efficacy. A topical study shows effect application on surgically induced skin wound in rat model. Contact angle measurements confirm (11.37°), while Fourier-transform infrared spectroscopy indicates effectiveness (carboxylic acid and amine groups). Allantoin distributed surface inside amorphous surrounded heterogeneous...
Carbon nanotubes with single and few walls are highly appreciated for their technological applications, regardless of the limited availability due to high production cost. In this paper we present an alternative process that can lead lowering manufacturing cost CNTs only by means use spray pyrolysis technique. For purpose, ferrocene is utilized as a catalyst aliphatic alcohols (methanol, ethanol, propanol or butanol) carbon source. The characterization was performed scanning electron...
We present the structural and spectroscopy characterization of carbon nanotubes (CNTs) grown by spray pyrolysis technique, using ferrocene as catalyzer cyclohexanol source, synthetized in a temperature range 750 to 1000°C. The morphology was observed scanning electron microscopy (SEM) transmission (TEM). response obtained UV-Vis Raman spectroscopy. morphological changes found that product yield seems increase with temperature. optical corroborated presence <mml:math...
The wave equation is a direct but complex approach to solve analytically for the Chladni figures, mainly because of complications that non-smooth and open boundary conditions impose. In this paper, we present an alternate solution model based on principle Huygens-Fresnel ideas Bohr hydrogen atom. proposed has been implemented numerically compared, with good agreement, our own experimental results case thin homogenous circular plate boundaries.

Bacterial biofilm that formed when the Ti6Al4 V alloy was exposed to Escherichia coli, monitored over 48 h by electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (PP) estimate rate of corrosion influence bacteria on this process. High-resolution scanning electron microscopy used examine bacterial growth, colonisation process formation. Our results highlighted several critical points regarding impact E. coli its use as a model for monitoring formation biocorrosion...

This work presents the effect of synthesis time on morphology and its influence optical properties microwave-assisted carbon nanospheres. To analyze correlation between growth in size nanospheres, nanostructures was characterized by scanning electron microscopy (SEM) X-ray diffraction (XRD). Their were analyzed UV-Vis spectrophotometry, Tauc method used to estimate band gap. The results reveal that variation does have a significant size, shape, amount sample obtained. presented slight...
Carbon nanotubes of various diameters and length were grown through the alternative spray pyrolysis method [1-2], using propanol, buthanol cyclohexanol as carbon source, at temperatures higher than 700°C.In this investigation,we present a comparative analysis structures morphology three samples by Raman spectroscopy in order to verify whether it is possible, method, obtain small low cost.The spectra acquired LabRam Horiba HR system He-Ne laser 632.8 nm 14.2 mW, equipped with CCD detector...
We have performed a comparative study of electrical properties between pristine and nitrogen doped (at low concentration) single wall carbon nanotubes (SWNTs), for three zig-zag cases: (6,0), (8,0) (9,0). The results were obtained through the Density Functional Theory (DFT) with Generalized Gradient Approximation (GGA) in relaxed CC bond length long-wavelength limit. stability structures was determined by calculating total energies N-doped structures. From calculations energy loss function,...
