Engineered nanomaterials are increasingly used in everyday life applications and, consequence, significant amounts being released into the environment. From soil, water, and air they can reach organelles of edible plants, potentially impacting food chain human health. The potential environmental health impact these nanoscale materials is public concern. TiO2 ZnO among most terms production amounts. Our study aimed at evaluating effects large-scale (~100 nm) (~200 nanoparticles on soybean...
Our study is focused on the structural and morphological characteristics, optical behaviour photocatalytic properties of undoped 5 at% Eu3+-, Gd3+- Y3+-doped CeO2 nanoparticles prepared by a green hybrid sol-gel combustion method. Several techniques such as X-ray diffraction powder (XRD), Transmission Electron Microscopy (TEM), UV-Vis spectroscopy, Photoluminescence spectroscopy (PL) Paramagnetic Resonance (EPR) have been used to investigate obtained samples. Moreover, correlation between...
Various powders of graphene oxide (GO), GO with silver (GO-Ag) and zinc (GO-ZnO) were obtained. The silanized (3-aminopropyl) triethoxysilane (APTES) aiming to be used, in a future stage, as additives the hydraulic lime mortars composition. characterized by Fourier Transform Infrared Spectrometry (FTIR) Scanning Electron Microscopy (SEM) before after silanization process. GO, GO-Ag, GO-Ag-APTES, GO-ZnO GO-ZnO-APTES also investigated Thermogravimetric Analysis (TG/DTA) Ultraviolet–Visible...
Agricultural waste from the fruit and vegetable industry is used as an alternative source of animal feed, but detailed investigations are required. The aim this work was to conduct a physico-chemical characterization, through analytical techniques, wastes such those golden apples, red carrots, celery, beetroots, potato peels. bioactive compounds in samples indicated high carbohydrate content 50.38 g/100 g apples 59.38 mg/100 organic acids celery. In addition, total phenolic (TPC, mg gallic...
The aim of the paper is to obtain and characterize k-carrageenan–chitosan dual hydrogel multilayers shell BSA gel microcapsules, as a carrier for curcumin, possible antitumoral agent in biological studies. We used CaCO 3 template synthesize non-toxic /BSA particles microtemplates by coprecipitating CaCl 2 solution that contains dissolved BSA, with an equimolar Na CO solution. microcapsules assembled through layer-by-layer deposition technique calcium cross-linked k-carrageenan alternating...
The study evaluated the impact of graphene powders used as additives in recipe experimental lime mortar to a mixture ratio 1:2.5 NHL3.5 hydraulic lime:fine sand. content binder, aggregate and water was kept constant, varying only amount type added relation natural NHL3.5. following five types mortars were prepared follows: reference (without additive); containing 1 wt.% GO 5 powder; with mixture: powder functionalized silver nanoparticles fly ash (GO-Ag + GO-fly ash); zinc oxide titanium...
Abstract Thermal and catalytic degradation of polystyrene waste over two different samples natural volcanic tuff catalyst comparative with Florisil has been carried out in order to establish the conversion degree into styrene monomer. The (PS) was subjected a thermal process range 380–500°C presence studied catalysts ratio 1/10 mass, catalyst/PS. were characterized by N2 adsorption-desorption isotherms (BET), Scanning Electron Microscopy (SEM) Fourier-transform infrared spectrometry (FTIR)....
Abstract ZnO nanoparticles (ZnO‐NP) were prepared by a facile precipitation technique using di‐isopropyl amine as precipitating agent. The morpho‐structure and porosity of the as‐prepared nano‐powder investigated FT‐IR analysis, X‐ray diffraction (XRD), scanning electron microscopy (SEM), BET analysis. By drop‐casting, composite film was deposited to obtain ZnO‐NP‐Nafion/GCE modified electrode. electrode cyclic voltammetry, electrochemical impedance spectroscopy, square wave anodic stripping...
