A successful drilling operation depends strongly on a useful drilling fluid system. Using nanoparticles (NP)s to formulate intelligent drilling fluids gives them a wide range of optimal properties under different operating conditions and resolves any operational problems. In this study, in order to provide an effective solution for improving the rheological and high pressure/high temperature […]
Green synthesis of metal nanoparticles (MNPs) is attracting the attention of chemists as it is cost effective and environment benign technique. Hence it is preferred to methods which use toxic reagents in the synthesis of MNPs. In. In this study, copper oxide nanoparticles (Cu2ONPs) were synthesized using Allium cepa (AC) and Raphanus sativus (RS) aqueous […]
The synthesis of bis(indolyl)methane derivatives in the reaction between indoles and aldehydes was carried out in a short reaction time (10-20 minutes) with good yield (78-96%) by using 1 mol% of nanoγ-Al2O3in H2O as a green solvent at room temperature. Moreover, we usednanoγ-Al2O3 as an effortlessly accessible, less costly, and possible under eco-friendly conditions catalyst […]
In this paper, the design of a novel low-power Min/Max circuit using Carbon Nanotube Field-Effect Transistor (CNTFET) technology has been discussed. By employing a new structure for the implementation of digital comparator, a high performance configuration has been obtained which consumes small area on chip due to the low transistor count used for its implementation. […]
The present investigation evaluates the potential of aqueous seed extract of Abrus precatorius L. for the biosynthesis of silver nanoparticles (AgNPs). The structure of AgNPs was authenticated by the changes in colour as well as the UV-vis spectroscopy, which showed an absorbance maxima peak at 441 nm. The scanning electron microscope (SEM) investigation proved the […]
In the present work the flow boiling charecteristics of CuO/water nanofluid were studied experimentally and the statistical as well as regression analysis were conducted to asses the flow boiling heat transfer coefficient and the influencing parameters. For this, CuO/water nanofluid was prepared by two step procedure for the particle concentration of 0.001%, 0.005%, and 0.01 […]
In this paper, the thermoelectric properties of zigzag single-walled carbon nanotubes (SWCNT) and zigzag single-walled boron nitride nanotubes (SWBNNT) are investigated. For this purpose, the chirality is considered as (9, 0). The characteristics are computed at three arbitrary temperatures of 200K, 300K, and 500K. Results show the Seebeck coefficient of zigzag SWCNT increases by increasing […]
The aim of this study was to prepare, the physicochemical assessment and the cytotoxicity testing of cisplatin-loaded mesoporous silica nanoparticles against head and neck squamous cell carcinoma cell line (HNSCC). Cisplatin-loaded mesoporous silica nanoparticles were prepared through the precipitation method. The prepared nanoparticles were evaluated by conventional methods in terms of physicochemical properties. The cytotoxic […]
In the current investigation phytochemically mediated, easy, efficient, and eco-friendly green synthesis of silver nanoparticles (AgNPs) was carried out using Entada rheedii leaf extract as a reducing and capping agent in a microwave-assisted synthetic pathway. UV-Visible spectroscopy, IR spectroscopy, scanning electron microscope (SEM), and transmission electron microscopic (TEM) techniques were used to confirm the formation […]
Synthesizing plant-derived nanoparticles attract attention due to both their broad-spectrum biological applications and sustainable production. This paper describes the production of Cobalt oxide nanoparticles (Co3O4 NPs) using M. charantia leaf extract. The Uv–Vis absorption spectrum of them has peaks at 309 and 595nm. FTIR spectroscopy reveals bands at 580cm-1 and 667cm-1 and confirms the formation […]
