1. Study of nanocomposites with carbon nanotubes and their tendency for carbon organization

Abstract The carbon derived from the thermal treatment of modified phenolic resins (PR) tends to organize into graphitic lamellae or turbostratic carbon and is commonly considered non-graphitizable. In this study, nanocomposites were synthesized with modified phenolic resin (Novolac) used as the matrix and oxidized multi-walled carbon nanotubes (NTox) in amo

2. High-frequency devices effect in vitro: promissing approach in the treatment of acne vulgaris?

Abstract Background: Acne vulgaris is an inflammatory skin disorder leading to an impairment of quality of life and is therefore not only a cosmetic issue. Its pathogenesis is multifactorial - of particular importance is the colonization with the bacterium Propionibacterium acnes. A wide range of different treatment options exists including topical and syst

4. Analysis and evaluation of structural properties of Co3O4 microparticles obtained at low temperature

Abstract In the present research, the synthesis of cobalt oxide Co3O4 was carried out using the sol-gel technique with subsequent heat treatment at 225 and 235 °C. The final product obtained was characterized by X-ray diffraction (XRD), showing a pure crystalline phase of Co3O4, cell parameters a=b=c=8.071 Å, and a volume of 525.7 Å3. The particle size wa

7. Effect of pH level and calcination on the production of calcium phosphates by acidic route of wet precipitation

Abstract Multiphasic calcium phosphate powders were synthesized by the acidic route, using lactic acid as a chelating agent that allows the production of a stable and rich solution of calcium and phosphate ions at room temperature. After pH adjusting, without varying the concentrations of precursor solution, XRD and FTIR analyses showed different CaP phases
