We present an experimental visualization study of centrifugal spinning, which is a novel method of producing nanofibers. The investigation was conducted using Newtonian and viscoelastic fluids to study the effect of viscoelasticity, driving force, and the flow rate on the initial thinning behavior, jet contour shapes,…

Molecular spin-crossover (SCO) compounds are attractive for information storage and photovoltaic technologies. We compared two prototypic SCO compounds with Fe(II)N6 (1, [Fe(phen)2(NCS)2], with phen = 1,10-phenanthroline) or Fe(III)S6 (2, [Fe(dedtc)3], with dedtc = N,N'-diethyldithiocarbamate) centers, which show abru…
This work reports on a high-voltage, hybrid capacitor involving two separate redox reactions. Aqueous solutions of Mg(NO3)2 and KI have been used for negative and positive electrode, respectively. Adjusting pH=2 for electrode (+) with KI solution and modifying Mg(NO3)2 solution to pH=9 for negative side play a crucial…
The infrared absorption and Raman scattering spectra of the monoclinic P21 l-aspartic acid anhydrous crystal were recorded and interpreted with the help of density functional theory (DFT) calculations. The effect of dispersive forces was taken into account, and the optimized unit cells allowed us to obtain the vibrati…
P <sub>5</sub> W <sub>30</sub> stabilized Au nanoparticles and graphene oxide were fabricated to form composite films exhibiting good electrocatalytic activity for H <sub>2</sub> O <sub>2</sub> reduction.
Abstract Synthesis and characterization of a highly efficient photoconductive nanocomposite comprising of two common metal oxides: copper oxide (CuO) and silicon dioxide (SiO 2 ) are being reported in this paper. The CuO/SiO 2 nanocomposite has been synthesized using a cost-effective and facile sol gel route. The stru…
2D nanoelectronics based on single-layer (SL) MoS2offers great advantages for ubiquitous electronics. With new device technology, highly uniform E-mode FETs using SL CVD MoS2with positive VT, large mobility, excellent subthreshold swing are achieved. The integrated inverter shows excellent voltage transfer characteris…
In this work, we have presented the green synthesis of silver nanoparticles (Ag-NPs) using extracts of Pistiastratiotes L. as reducing agent. The silver nitrate (AgNO 3 ) solutions were used as precursor. The experiments were performed under irradiation with a light that can help to increase the activation for reducti…
BACKGROUND: The constant increase of the use of nanomaterials in consumer products is making increasingly urgent that standardized and reliable in vitro test methods for toxicity screening be made available to the scientific community. For this purpose, the determination of the cellular dose, i.e. the amount of nanoma…
There are several accepted methods used for X‐ray diffraction analysis on graphene layers and sample's stacking height L C . The Scherrer equation is avoided since the layers in the graphene samples are non‐uniformly distributed and therefore the samples have non‐uniform thickness. Instead, a model that includes thick…
SF6is widely used in C-GIS as an insulating medium. However, SF6and its decomposition products can pollute environment and harm human health and equipment. Firstly, this paper verifies the high-energy discharge promotes CF3I to produce C2F6 and I2 by simulation. Therefore the paper puts forward the significance of usi…
A novel based electrochemically active various electrodes (Carbon nanotube, metal oxides, conducting polymers and nanocomposites) materials has been overviewed for the development of supercapacitor applications. Different kinds of morphological (Flowers, nano fibers, nano wires, nano rod and nanoporous) based electrod…
Nanofibers have emerged as advanced fibers with broad use and potential in biomedical fields in recent decades. The process of healing is an innate immune response towards a pathophysiology such as wound. Ordinary time taken for wound healing is approximately 2–3 days depending upon the chronic state. Air moisture and…
High Resolution Image Download MS PowerPoint Slide We calculated the absorption coefficient of colloidal wurtzite CdSe/CdS nanocrystals (NCs), ranging from spherical to strongly elongated shapes (aspect ratio up to 21) by correlating the NC absorbance spectrum to the NC elemental composition and overall dimensions. We…
Compared with the inert metal (gold), the active metal (Cd) is much more prone to oxidation, leading to its high oxidation state. In this work, we found that doping the homogold Au 25 (SR) 18 nanocluster with cadmium largely enhances its stability. The differential pulse voltammetry (DPV) analysis suggested that Cd do…
Guanidinium trichloroacetate (GTCA), a novel organic single crystal was grown by a slow evaporation technique. The single crystal X-ray diffraction study revealed that the GTCA crystal belongs to tetragonal crystal system with the space group P4 1 . From the linear optical studies, the lower cut-off wavelength of grow…
Corrosion of oil and gas pipelines significantly reduces the service life of the pipelines, thus increasing costs, and more seriously, it can cause catastrophic environmental accidents. More recently, the exploitation of oil in ultra-deep seawater fields is facing new technological challenges in material selection owi…
Recent progress in quantum dot (QD) sensitized solar cells has demonstrated the possibility of low-cost and efficient photovoltaics. However, the standard device structure based on n-type materials often suffers from slow hole injection rate, which may lead to unbalanced charge transport. We have fabricated efficient…
