Synthesis, optical, photocatalytic, and electrochemical studies on Ag2S/ZnS and ZnS/Ag2S nanocomposites
Applied Nanoscience - Tập 6 - Trang 503-510 - 2015
Novel Ag2S/ZnS and ZnS/Ag2S nanocomposites were synthesized by a simple chemical method in air. Different morphologies were obtained for Ag2S/ZnS nanocomposites annealed at different temperatures. The products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), UV–visible absorption, and photoluminescence (PL) spectroscopy. Thermal stability and phase transition of t......
Development of methotrexate-loaded cubosomes with improved skin permeation for the topical treatment of rheumatoid arthritis
Applied Nanoscience - Tập 9 - Trang 1781-1796 - 2019
Methotrexate-loaded cubosomes (MTCs) were developed to provide relief from pain/joint stiffness, by affording stable methotrexate concentration at the targeting sites through sustained pattern by non-invasive skin route with enhanced permeation upon skin, for the treatment of rheumatoid arthritis. Non-ionic surfactant poloxamer 188 works to enhance the permeation of methotrexate. The results of FT......
Physico-chemical properties of anti-corrosion pigment based on nanoporous zeolite and zinc monophosphate
Applied Nanoscience - Tập 13 - Trang 4685-4692 - 2022
It was studied a composite pigment based on nanoporous zeolite Na-A and zinc monophosphate synthesized by the mechanochemical method. The largest specific surface area achieved for zeolite dispersed particles is 65.3 m2/g, and their crystal structure is preserved after mechanochemical modification in a planetary mill for 60 min at 200 rpm. Mechanochemical treatment of a mixture of zeolite Na-A/Zn(......
Synthesis of ZnO submicron spheres by a two-stage solution method
Applied Nanoscience - Tập 2 - Trang 63-70 - 2011
This paper presents a two-stage method to synthesize the mono-dispersed ZnO spheres. The size and uniformity of ZnO spheres can be controlled in the sub-micrometer range. This makes the method applicable to the fabrication of photonic crystal structures. The effects of different reaction parameters such as reaction temperatures, reaction times, and water concentrations on the formation of ZnO sphe......
Experimental study on polishing performance of CeO2 and nano-SiO2 mixed abrasive
Applied Nanoscience - - 2018
In this paper, superfine SiO2 nanoparticles are utilized as composite abrasive additive to improve the polishing property of CeO2, which is prepared through chemical precipitation method by rare-earth chloride as raw materials, silicofluoric acid as fluoride, Na2CO3 as modifier, and NH4HCO3 as precipitator. XRD, SEM, particle size analyzer, and atomic force microscopy are applied to characterize t......
A molecular dynamics simulation study for the mechanical properties of different types of carbon nanotubes
Applied Nanoscience - Tập 2 - Trang 377-383 - 2012
Carbon nanotubes have caught tremendous attention of the researchers during the last decade due to their excellent mechanical, electrical, optical and thermal properties. The exploitation of these fibers as reinforcing agents in making strong fiber composites has been a primary research topic in the recent investigations on composite materials. Although the theoretical results are rather optimisti......
In situ detection of oil leakage by new self-sensing nanocomposite sensor containing MWCNTs
Applied Nanoscience - - 2021
One of the ever-existing concerns for operators in the oilfield industry is the integrity of the equipment used. Thus, in this crucial sector, an essential task involves developing extremely sensitive, reliable, and cost-effective techniques to detect and monitor oil spills. On this basis, the focus of this study is the creation and examination of the electrical resistance differences of novel sel......
Electro-conductive and temperature-sensitive poly(N-isopropylacrylamide) composite hydrogels with improved mechanical properties
Applied Nanoscience - Tập 10 - Trang 2189-2198 - 2020
Poly(N-isopropylacrylamide) (PNIPAAm) hydrogel with temperature-sensitive properties can be potentially applied in smart response area. However, poor mechanical and non-conductive characteristic have greatly restricted its widespread application. In this work, PNIPAAm composite hydrogels containing graphene aerogel (GA) and graphene oxide (GO) were prepared via vacuum-assisted backfilling and in-s......
Highly sensitive sensor probe development with ZCCO nano-capsule composites for the selective detection of unsafe methanol chemical by electrochemical technique
Applied Nanoscience - Tập 12 - Trang 1571-1584 - 2022
In this approach, an electrochemical sensor for the detection of methanol was assembled by depositing ZnO/CdO/CuO nanocapsules (ZCCO NCs) as a thin layer on the flat surface of glassy-carbon electrode (GCE) to result in the working electrode of the proposed methanol sensor probe. The characterization of wet-chemically prepared ZCCO NCs were performed by analyzing using including Fourier Transform ......
Enhancement of solid-phase thermal conductivity and specific heat of solar salt through addition of MWCNT: new observations and implications for thermal energy storage
Applied Nanoscience - Tập 9 - Trang 2117-2126 - 2019
Solid-phase thermophysical properties of solar salt (a mixture of NaNO3 and KNO3) influence the performance of sensible heat and latent heat thermal energy storage systems. Solar salt’s lower thermal conductivity imparts kinetic limitation during the discharge cycle and hence its thermal conductivity needs to be enhanced. This work is aimed at studying the influence of MWCNT incorporation on the i......
