In this study, multi-walled carbon nanotubes (MWCNTs) were decorated with different types of nanoparticles (NPs) in order to obtain hybrid materials improved antimicrobial activity. Structural and morphological analysis, such as Fourier transformed infrared spectroscopy, Raman X-ray diffraction, transmission electron microscopy, environmental scanning microscopy/energy-dispersive spectroscopy the Brunauer–Emmett–Teller technique used investigate decoration NPs. Analysis showed a narrow size...
Nanotechnology can offer a series of new “green” and eco-friendly methods for developing different types nanoparticles, among which the development nanomaterials using plant extracts (phytosynthesis) represents one most promising areas research. This present study details use lavender flowers (Lavandula angustifolia Mill., well-known their in homeopathic applications) biosynthesis silver nanoparticles with enhanced antioxidant antibacterial properties. Several qualitative quantitative assays...
Three complexes of Cd(II), [Cd(NA)₂(NO₃)₂(H₂O)₂] (1), [Cd(NA)₂(NO₃)₂(H₂O)₂]·2NA (2), and [Cd(ox)(NA)(H₂O)]·H₂O (3) (NA = nicotinamide, ox oxalate) were synthesized characterized. Complexes (1) (2) are mononuclear, while complex is a bidimensional polymeric coordination compound, with oxalate anions bridging metal ions in two different ways: µ₂ bis-bidentate chelating manner µ₄ bis-monodentate manner. The stereochemistry Cd(II) compounds distorted pentagonal bipyramid, compound it regular...
Honey is a highly valued natural product with antioxidant, antimicrobial and anti-inflammatory properties. However, its antioxidant activity (AOA) not as high that of other honeybee products, such propolis. Several polyphenol—honey formulations have been proposed up to now, most them using maceration biomass in honey or mixtures liquid extracts, which either limit polyphenols bioavailability destroy the characteristics honey. To improve health benefits by increasing AOA keeping structural...
Raw materials, such as collagen and chitosan, obtained from by-products the food industry (beef hides crustacean exoskeletons), can be used to obtain collagen-chitosan composite biomaterials, with potential applications in regenerative medicine. Functionalization of these biomaterials is a possibility, thus, resulting molecule medicine, namely clotrimazole (a antibacterial, antifungal, antitumor activity), at mass ratio (collagen-chitosan-clotrimazole) 1:1:0.1. This functionalized...
The objective of this work was to develop a sustainable process for the extraction anthocyanins from red cabbage byproducts using, first time, apple vinegar in extractant composition. Our results showed that mixture 50% (v/v) ethanol-water, acidified with vinegar, used proportion 25 g by-products per 100 mL solvent, best solvent preparation an anthocyanin extract good stability food applications. chemical characterization performed by FTIR, UV-VIS, HPLC-DAD, and ICP-OES. evaluated...
Abstract Recycling of electric and electronic equipment is an emerging global issue in order to decrease the high amount waste deposited on landfill or incinerated, thus reducing environmental pollution. Different strategies eliminating this can be applied. In paper, non‐metallic fraction printed circuit boards, due contained glass fiber rigid epoxy matrix, are considered suitable for valorization as reinforcing filler polyvinyl chloride recovered from insulation cables. The composites...
The ionic association constants of sodium with carbonate ion (K1C') and acidic ions (K2C') were measured in NaCl-NaHCO3-H2O ternary systems to determine the distribution among chemical species present growth medium Chlorella homosphaera 424 algae. mean activity coefficients chloride (in pure a mixture electrolytes) determined experimentally using two electrochemical cells, namely Ag, AgCl| KCl (3 M)|| NH4NO3 (1 M)| NaCl (mNaCl)| Na+-ISE AgCl|KCl Cl--ISE. studies carried out show that values...
Annually, considerable amounts of polluted water are produced due to industrialization based on processing in various industries. The purpose this study refers a process obtaining photocatalytic system with structure metal oxides the field ultrasound, used advanced treatment wastewater resulting from pharmaceutical and agricultural These systems allow be treated relatively short time, being quickly recovered reused repeatedly. To quantify efficiency photocatalyst treating wastewater,...
As a result of population growth and changes in lifestyles, livestock meat production is increasing throughout the world. Therefore, large amount keratinaceous waste generated annually from food leather industry. The conventional method hair removal industry through all chemical processes used creates great concern for environment, being major contributor to water. enzymatic process microorganism an eco-friendly option reduce oxygen demands processing. In biodegradation bioremediation...
