Abstract The construction of self-powered micro-electro-mechanical units by converting the mechanical energy of the systems into electrical power has attracted much attention in recent years. While power harvesting from deterministic external excitations is state of the art, it has been much more difficult to derive m…
High Resolution Image Download MS PowerPoint Slide Ionic liquids are a natural choice for supercapacitor electrolytes. However, their cost is currently high. In the present work, we report the use of ternary mixtures of sulfolane, 3-methyl sulfolane, and quaternary ammonium salts (quats) as low-cost alternatives. Sulf…
A continuous low-stress diamond film has been prepared on stainless steel by a novel two-step dropped power process using a Cr/CrN/CrTiAlN film as an interlayer. After the interlayer was deposited on the stainless steel, isolated diamond particles were firstly prepared under high power of 1800 W for 10 min in CVD, whi…
Atomic force microscopy (AFM) images give valuable information about surface roughness of thin films based on the results of power spectral density (PSD) through the fast Fourier transform (FFT) algorithms. In the present work, AFM data are studied for silver and gold nanoparticles (Ag NPs a-C: H and Au NPs a-C: H) em…
Chemical insights from simulations help to design a phase-change material that can crystallize in less than a nanosecond
The problem of suppressing the scattering from conductive objects is addressed in terms of harmonic contrast reduction. A unique compact closed-form solution for a surface impedance Zs(m,  kr) is found in a straightforward manner and without any approximation as a function of the harmonic index m (scatte…
Materials with a large magnetocaloric response are associated with a temperature change upon the application of a magnetic field and are of interest for applications in magnetic refrigeration and thermomagnetic power generation. The usual metric of this response is the gravimetric isothermal entropy change $\mathrm{\e…
Herein, we combine several methods to characterize the fibrils formed by a TTR 105–115 mutant in which Leu111 is replaced by the unnatural amino acid aspartic acid 4-methyl ester. We find that this mutant peptide exhibits significantly different aggregation behavior than the wild-type peptide: (1) it forms fibrils wit…
X-ray photon correlation spectroscopy (XPCS), an extension of dynamic light scattering (DLS) in the X-ray regime, detects temporal intensity fluctuations of coherent speckles and provides scattering vector-dependent sample dynamics at length scales smaller than DLS. The penetrating power of X-rays enables probing dyna…
Al <sub>2</sub> W <sub>3−x</sub> Mo <sub>x</sub> O <sub>12</sub> shows an orthorhombic to monoclinic transition with increasing Mo concentration and ∼100 mA h g <sup>−1</sup> capacity at 100 cycles in Li-cells.
The optical and electrical characteristics of a graphene oxide solution (GS) with different graphene oxide (GO) concentrations in de-ionized water are investigated via the electrochemical impedance spectroscopy (EIS) method. The measurement results produced by the EIS for the GS are represented with both Bode and Nyqu…
Sensitivity of lead detection (upto 0.1 nM) is greatly improved by enhancing the reactivity and stability of small gold nanoparticles.

Controlling the properties of quantum dots at the atomic scale, such as dangling bonds, is a general motivation as they allow studying various nanoscale processes including atomic switches, charge storage, or low binding energy state interactions. Adjusting the coupling of individual silicon dangling bonds to form a 2…

The objectives of this study were to determine the effects of 1) the extraction temperature (65, 75, 85, and 95°C) of chicken feet gelatin (CFG) and 2) CFG extracted at different temperatures and wheat fiber (WF) with different particle sizes (80, 250, and 500 μm) on the physicochemical properties of the resultant gel…
nanosheets (NSs) was retained in its supported form and hence, such supported materials can be effective for the abstraction of toxic lead from water, with fast kinetics.
Soil texture has been found to be a critical factor in regulating the fate and transport of cerium oxide nanoparticles (CeO 2 NPs) in the terrestrial environment. However, the underlying mechanisms for the interactions between CeO 2 NPs and different components of soil are still poorly understood. The attachment of Ce…
BACKGROUND: Peptides are promising compounds for use in inorganic or organic-inorganic hybrid syntheses (mineralization) and offer several advantages over proteins. Meanwhile, silica-based nanomaterials have been extensively investigated for many years because of their potential application in a diverse range of techn…
The effects of a fluorine-containing compound (4,4′-difluorobenzophenone; DF) on the electro-optical and dielectric properties of polymer-stabilized blue phase (PSBP) liquid crystals were investigated. When a PSBP cell was driven by an in-plane electric field, the addition of DF up to 2.7 wt% effectively reduced the o…
