The paper depicts some advanced technologies in order to install a low power consumption and reconfigurable sensor networks, which presents optimal operation and excellent reliability. The results of this paper are prepared during a research project that implements a low power microsystem in package so that the antenna and the radio interface are co-integrated. Consequently, […]

In this article are presented the results of 113 women of reproductive age study. The control group included 45 healthy women (the age range 22-47 years) who had no urogenital, endocrine system diseases or surgical intervention, no earlier than 9 months after the last birth and at least 3 months of regular menstrual cycles. The […]

Different artificial sweeteners were studied in blood medium as electrolyte by cyclic voltammetric technique using modified glassy carbon electrode with carbon nanotubes to determine the diffusion coefficient for the redox current peaks of artificial sweetener by Randles-Sevcik equation. It was determined the viscosity of the blood medium after the addition of the artificial sweetener to […]

Gold coated mesoporous silica magnetic nanocomposite (mSiO2@Fe3O4 @Au) was synthesized using ethylene glycol (EG) as template at two different ratios of EG: TEOS of 0.1 and 0.6. The chemistry, morphology, optical and magnetic properties of the obtained nanocomposites were characterized by Fourier Transform (FTIR), Scanning Electron Microscopy (SEM), Transverse Electron Microscopy (TEM), Atomic Force Microscopy […]

Highly-porous ceramics samples based on nanostructured biogenic hydroxyapatite and superfine fumed silica have been prepared using a foam replication method at a sintering temperature of 850°C. They were shown to possess a total porosity 86-89 % and a permeable open-porous (~ 90 % of the total porosity) structure with pore sizes in the range 500-1000 […]

This study aimed to develop a sustained-releasing asiaticoside-loaded liposome with well lung-targeting. Liposomes were prepared by film-dispersion and extrusion method. The rotatable central composite design (RCCD) with three-factor and five-level were applied to evaluate the optimization experiments. To maximize the percentage encapsulation efficiency (EE) and drug loading, a quadratic polynomial model was generated to predict […]

ENFETs are field-effect transistors integrated in the same chip with their recognition enzymatic elements, applied to bio-molecules detection like urea, creatinine, glucose, pesticides and so on. Despites to the recent developments, the concept of the ENFET designing is pretty complex and challenging, requiring microelectronics, electro-chemistry and bio-recognitions knowledge. Therefore, this paper presents some punctual advances […]

Here, the Baicalin-loaded PLGA microspheres (BC-MS) were prepared, and their properties in vitro and in vivo were evaluated. The microspheres were prepared using the solvent evaporation method based on O/W emulsion. The HPLC method was established in the determination of the content of baicalin in the microspheres. The surface and particle size were observed by […]

In this work, the effect of sonication on the size, morphology, and stability of gold nanostars was investigated for the first time. It was found that the seed-mediated method, followed by the sonication treatment developed in this study, offers new opportunities to synthesize aqueous suspensions of monodispersed gold nanostars with prolonged stability. The results indicate […]

This work reports on successful one pot surfactant free in-situ synthesis of cobalt doped ZnO-chemically converted graphene (CCG) nanocomposite (CZG) by adopting a low temperature solution process utilizing zinc acetate dihydrate and graphene oxide with varying content of cobalt acetate tetrahydrate (upto 10% Co with respect to Zn) in the precursor medium. The materials properties […]
