The toxicity effects of silver (nAg) and zinc oxide (nZnO) engineered nanoparticles (ENPs) on the duckweed Spirodela punctuta were studied to investigate potential risks posed by these ENPs towards higher aquatic plants. influence media abiotic factors stability was also evaluated. Marked agglomeration observed after introduction into testing whereby large particles settled out suspension accumulated at bottom vessels. high ionic strength (IS) promoted because it reduced inter-particle...

HDA-capped ZnO nanoparticles were prepared by solvothermal method using solvents of different polarities. A number parameters kept constant such as temperature, pressure, time, and pH while varied, that is, water, ethanol, acetone. The TEM was used for the structural properties morphologies spheres, mixture rods, spheres stars obtained in acetone, respectively, a given reaction time 15 minutes. Both ethanol acetone gave rods with high aspect ratio primarily because lengths rods. Water have...

Glutathione-capped copper sulfide (CuxSy) nanoparticles with two different average sizes were successfully achieved by using a simple reduction process that involves only changing the reaction temperature. Temperature-induced changes in size of CuxSy resulted particles optical, morphological, and electrochemical properties. The dependence sensing properties on was studied voltammetric amperometric techniques. spherical particle 25 ± 0.6 nm found to be highly conductive as compared 4.5 0.2...

Abstract Carbon nanotubes (CNTs) containing Nafion composite membranes were prepared via melt‐blending at 250 °C. Using three different types of CNTs such as pure (pCNTs), oxidised (oCNTs) and amine functionalised (fCNTs); the effect surface oxidation well functionalisation in was investigated by focussing on aspects: thermo‐mechanical stability, thermal degradation proton conductivity. The oCNTs‐containing membrane exhibited concurrent improvement most properties compared to that or other...

Plain polyvinyl alcohol (PVA) nanofibres and novel benzene tetracarboxylate incorporated with strontium, lanthanum antimony ((PVA/Sr-TBC), (PVA/La-TBC) (PVA/Sb-TBC)), respectively, where TBC is 1,2,4,5-tetracarboxylate adsorbents, were fabricated by electrospinning. The as-prepared electrospun characterized scanning electron microscope (SEM), Fourier transform infrared (FTIR) thermogravimetric analysis (TGA). Only plain PVA followed the Freundlich isotherm a correlation coefficient of...

A series of MgO nanoparticles were prepared by first precipitating and isolating Mg(OH)2 from Mg(NO3)2 at three different temperatures using NaOH followed their thermal decomposition also temperature settings. The effects which precipitation the hydroxide occurred studied to assess influence on nanoparticle size surface area. synthesised characterized a suite techniques including Brunauer-Emmett-Teller (BET), X-ray diffraction (XRD), Transmission Electron Microscopy (TEM) Scanning Microscope...

Colorectal cancer (CRC) is among the leading causes of mortality. The lifetime risk developing CRC about 5% in adult males and females. usually diagnosed at an advanced stage, this point therapy has a limited impact on cure rates long-term survival. Novel and/or improved therapeutic options are needed. involvement microRNAs (miRNAs) development been reported, their regulation many oncogenic pathways suggests potent tumor suppressor action. Although miRNAs provide promising approach for...

This mini-review focuses on the use of dilute III-V semiconductors for near-infrared (NIR) sensing and detection tuberculosis (TB) in both humans animals. These composite materials could greatly improve sensitivity efficiency NIR detection. Well, we start off with effects TB, old methods detecting it, rise technologies. The significance is discussed fabrication, properties, performance these organic matrices explored. In this study test sensors TB across different species, discuss problems...

<title>Abstract</title> Textile manufacturing effluents exhibit high concentrations of Methylene blue (MB), with serious health impacts to both the population and environment. In this study, MB was removed from water using as-synthesized tungsten disulfide nanosheets produced at different residence times, yielding grey black coloured products (i.e., WS₂, G B). The morphological surface chemistry properties were determined SEM, HRTEM, FTIR, Rama spectroscopy, ZetaSizer. FTIR...

Titanium dioxide (TiO2) nanostructures were synthesized by microwave-assisted and conventionally heated hydrothermal treatment of TiO2 powder. The tubular structures converted to a rodlike shape sintering the samples at various temperatures in air for 3 h. This was accompanied phase transformation largely influenced method synthesis mode heating. X-ray diffraction results are agreement with structural indicating gradual changes crystallinity as prepared samples. structure is found collapse...

The fate and behaviour assessment of ZnO- Ag-engineered nanoparticles (ENPs) bacterial viability in a simulated wastewater treatment plant (WWTP) fed with municipal was investigated through determination ENPs stability at varying pH continuous exposure to wastewater, respectively. were introduced 3-L bioreactor (simulated WWTP) hydraulic residence time (HRT) 6 h dose rate 0.83 mg/min for 240 h. the found be dependent on their dissolution aggregation different pH, where ZnO exhibited highest...
