Study of Dielectric and Piezoelectric Properties of (1-x)PZT-xSFN Ceramics Prepared by Conventional Solid State Reaction Method

Modified-PZT ceramics with a formula (1-x)Pb(Zr0.53 Ti0.47)O3-xSr(Fe2/3, Nb1/3)O3 (doped with isovalent: Sr2+, acceptor: Fe3+ and Donor: Nb5+ ions) abbreviated as (1-x)PZT-xSFN binary system with varying x (x= 0.02, 0.04, 0.06, 0.08 and 0.10) located near the morphotropic phase boundary (MPB) were prepared by a traditional process in a solid state. All the samples were sintered at a temperature of 1200°C during 2 h. The phase structure, the dielectric and piezoelectric properties of the system were studied. In-phase analysis used X-ray diffraction (XRD) at room temperature indicated that more

Investigation of the Effect of Substituent Species/Positions and Numbers on Removal of Toxicity from Chloro and Nitro Phenol Compounds with Fenton and Fenton-like Processes

Phenol derivatives containing substutient are used intensely in industry and their presence in surface and waste water is a problem requiring urgent solution due to their tendency for bioaccumulation, cancerogenic effects, high toxicity and weak biodegradability. In this study, the degradability and toxicity of chlorinated phenols 2-CP, 2,4-DCP and 4-CP and nitrated phenols 2-NP, 2,4-DNP and 4-NP were investigated. These phenols are included on the priority toxic pollutant list within the scope of clean water regulations according to both the US EPA-2014 and the European Union (2455/2001/CE) more

Applications, Challenges and Development of Nanomaterials and Nanotechnology

Nanomaterials and nanotechnology have been rapidly developed and widely applied in antimicrobial, biosensors, nanomedicine, nano-electronic technology, reinforcement, water treatment, and so on. However, there are also many problems and challenges during using and developing nanomaterials and nanotechnology. Are they secure enough for the health of human beings? Do they cause the environmental pollution? And how can we sustainably develop nanomaterial and nanotechnology? In this review, we introduced the applications, potential threats and hazards, and development and prospect of nanomaterial more

Synthesis and Applications of Antimicrobial and UV Protected Polymeric glass coatings

polymeric materials along with nanoparticles are widely used to protect from microbial propagation. In humid environments, enclosed edifice is amongst the foremost propagation substrates aimed at microorganisms. Antimicrobial coatings could help to stop microbial proliferation or, reduce the number of microorganisms growing on inside buildings. This paper deals with inhibition of Escherichia coli bacteria by TiO2 and silver nano-particles doping along with poly acrylate-based copolymers. Coated glass was characterized for FTIR, antimicrobial activity, UV Visible Spectroscopy and water contact more

Application of UV-Visible Spectrophotometric Method for the Estimation of Ciprofloxacin HCl and Levofloxacin Hemihydrate (Antibiotics) in Marketed Drugs

Ciprofloxacin HCl, 1-Cyclopropyl-6-fluoro-4-oxo-7-(piperazin1-yl)-1,4-dihydroquinoline-3-carboxylic acid, is a synthetic broad antibacterial compound belonging to the group of fluoroquinolones which is antimicrobial drug act through the inhibition of DNA-gyrase, an enzyme that is critical to bacterial chromosome replication. It is used in a wide range of infections of the urinary, respiratory and gastrointestinal tracts, as well as in skin structure and ocular infections. Levofloxacin Hemihydrate is a fluoroquinolone, has a broad-spectrum antibiotic activity against gram-positive and more

Photocatalytic Performance Evaluation of Bismuth Doped Tin-Dioxide under UV and Direct Sunlight Irradiation for Congo Red Dye Degradation

In the current research work, bismuth doped tin-dioxide (Bi-SnO2) was prepared by wet chemical co-precipitation method. The synthesized material was used as a photocatalyst in the degradation of congo red dye (CR) in its aqueous solution. The prepared catalyst was used in the uncalcined- and calcined forms for the photocatalytic reaction. The synthesized catalyst in both forms was characterized by UV-visible spectroscopy, scanning electron microscopy (SEM) and X-ray diffraction (XRD). The XRD revealed that the calcination of the Bi-SnO2 improved its crystallinity. The SEM showed that the more

Paper-Based Analytical Device for Rapid Naked-Eye Detection of Sulfide in Water Samples

This paper describes the development of a low-cost paper-based colorimetric analytical device for the accurate and rapid determination of sulfide. Under optimized conditions, Na2S was dropped in the uptake zone I and the probe in the uptake zone II, they converged to the detection zone via capillary force and formed an intense pink resorufin. Sulfide can be quantified based on the average color intensity values of the product “free resorufin”. The color intensity is recorded using a camera phone, and quantification was made using Adobe Photoshop. The as-developed analytical device detected more

Modified Zinc Oxide Nanoparticles for Corrosion Resistance Applications

Atmospheric corrosion is a big threat to the steel structures. This is because it compromises its structural integrity, aesthetic aspects and overall efficiency. An attempt has been made to counteract this through surface engineering of substrates including glass and steel by using modified zinc oxide nanoparticles to increase hydrophobicity. The synthesis of zinc oxide nanoparticles is carried out by using sol-gel method, thereafter these particles were modified by using stearic acid; a fatty acid. The zinc oxide nanoparticles were characterized by using X-ray diffraction analysis (XRD) more

Impact of Anionic Dopant Precursor on Nanostructured ZnO thin Films Surface Morphologies

The aim of this study is to investigate the impact of an anionic precursor [N2 gas and triethyleneamine (TEA) as nitrogen dopant source] to prepare anionic doped ZnO thin films surface morphologies, via a novel route - hydrothermal solution deposition at low temperature. The effect of dopant concentration under both with and without pH control was studied. The less populated doped ZnO crystal nearly had the same band gap as compared to undoped ZnO thin films. The photocatalytic activity of selected doped ZnO thin films were studied for the degrdation of 10 mg L-1 Methylene Blue under UV more

Removal of Acid Textile Dye from the Aqueous Solution by a New Adsorbent Obtained from Waste Cotton from the Garment Plant

The paper investigates the possibility of removing acid dye from the aqueous solution by an adsorption process on new adsorbent prepared from waste cotton textile from the ready-made garment industry. It is a waste generated during the cutting of the layers of cotton knitwear, which is practically the product from the textile cutting process. The obtained adsorbent is a bulk material with heterogeneous porous particles, of ragged shapes. In particle interiors, there are pronounced cracks, cavities and channels that form the basis of microporous material. The qualitative and quantitative more
