New forms of vanadium oxide Nanoporous were fabricated using a simple chemical synthesis method. Vanadium pentoxide (V2O5) Nanoporous were synthesized by sodium metavanadate as precursor and ethylene glycol as surfactant. The samples were characterized by high resolution transmission electron microscopy (HRTEM), field effect scanning electron microscopy (FESEM) and X-ray diffraction (XRD), Four...

The most common means of identification of gamma-hydroxybutyrate (NaGHB) involves using Fourier transform infrared spectroscopy (FTIR) or gas chromatography-mass spectrometry (GC-MS) of a suitable derivative. However, these methods may be complicated by possible shifts in chemical equilibrium between gamma-hydroxybutyric acid (GHB), GHB salts and the precursor lactone, gamma-butyrolactone (GBL)...

Native and peracetylated sporopollenin from the pollen of Typha angustifolia L. was investigated using several spectroscopic methods, inducing Fourier transform infrared spectroscopy (FTIR), solid-state 13C-nuclear magnetic resonance spectroscopy (13C-NMR) and X-ray photoelectron spectrometry (XPS). Interpretation of the experimental data shows that the greater part of oxygen found in sporopoll...

Main objective of this present study was to prepare and investigate the different pseudo polymorphic forms of gemifloxacin using Powder X-Ray Diffraction analysis (PXRD), Scanning Electron Microscopy (SEM), Differential Scanning Calorimetry (DSC), Fourier Transform Infrared Spectrometry (FTIR) and dissolution studies. For this purpose, crystals of gemifloxacin (G-1 to G-4) were obtained by solv...

N-vinylcarbazole (NVK) is proposed as an additive for acrylates thermal free radical polymerization (FRP) and epoxy thermal ring opening polymerization (ROP) at room temperature. The new initiating systems are based on a silane/silver salt/N-vinylcarbazole interaction, which ensures good to excellent polymerization. Moreover, the polymerization is much more efficient under air than under argon....

The influence of different application methods on UV protective properties of white and dyed cotton functionalized with ZnO nanoparticles (nano-ZnO) was investigated. The methods differ in application procedure, time of treatment and auxiliaries used in the treating bath. The ultraviolet protection factor (UPF) was determined for untreated and functionalized samples. The presence of nano-ZnO on...

It is possible to evaluate the taste of foods or medicines using a taste sensor. The taste sensor converts information on taste into an electrical signal using several lipid/polymer membranes. A lipid/polymer membrane for bitterness sensing can evaluate aftertaste after immersion in monosodium glutamate (MSG), which is called "preconditioning". However, we have not yet analyzed the change in th...

The detection and identification of microorganisms using spectroscopy techniques promise to be great value because their sensitivity, rapidity, low expense, simplicity. In this study, we used FTIR for the characterization Fusarium solani. PCR amplification DNA extracted from these isolates showed possibility amplifying products with sizes 559 bp ITS1-ITS4 primers. Based on phylogenetic tree ana...
