Abstract Recently, we reported the observation of superconductivity at ~0.5 K in a La2O2M4S6-type (M: metal) layered compound La2O2Bi3AgS6, which is a layered system related to the BiS2-based superconductor system but possesses a thicker Bi3AgS6-type conducting layer. In this study, we have developed the La2O2Bi3AgS6-…
We report the prediction of a two-dimensional (2D) allotrope common to group-IV and group-V elements and III-V compounds, which consist of two nonplanar atomic layers connected by vertical bonds and form deformed octagon, hexagon, and squares (dohs) with threefold and fourfold coordinated atoms. Specifically for silic…
We are concerned with controlling wave propagation in an elastic medium by engineering its dispersive properties. To this end, we discuss a flexible and systematic framework for designing the material composition of the unit cell of a periodic medium when given a target dispersion relation or, equivalently, a target g…
We report a unique phenomenon of physical adsorption of coumarin 6-β-cyclodextrin (C6-β-CD) inclusion nanostructures on graphene oxide (GO) nanosheets, thus inducing ground-state electron transfer from the C6-β-CD composite to GO. On excitation, the C6-β-CD composite initially transfers energy to the attached GO surfa…
ZnO, which has high electrochemical stability, wide band gap energy, large excitonic binding energy, intense near band excitonic emission and is non-toxic, have potential applications in all fields. This chapter reviews the structural, optical and electrical properties of undoped and doped ZnO thin films. The type of…
Abstract The thermal properties together with the identification of the emitted volatiles during heating of the starch-graft-poly(geranyl methacrylate) copolymers with the use of a TG/FTIR-coupled method and some of the physicochemical properties of the copolymers were determined. It was found that the use of the gera…
Nanomaterials had been used because of the properties they exert in such scale (<100 nm), and they have been used in a wide variety of products like paints, electronics, fabrics, and also personal care products. Recent manuscripts available in the literature demonstrate the potential benefits of nanotechnology with th…
It is greatly important to understand the gas bubble behaviors and realize their reliable manipulation. There still remain many challenges in the capture, transport, and release of gas bubbles at a preferred location intelligently. Herein, we provide a simple approach to manufacture a composite film with poly( N -isop…
Abstract The impact of different silica nanoparticles on rheology, interfacial tension and drop size distributions in liquid‐liquid systems is determined experimentally. The particles vary in wettability and specific surface area. In contrast to commonly used high‐energy devices for Pickering emulsion preparation, low…
Flexible micro-supercapacitors (MSCs) featured with high storage capacity and mechanical stability are essential and indispensable for the development of wearable devices. Since the active materials physically deposited on the current collectors are rigid and will be desquamated under the mechanical cycling, the perfo…
Hollow carbon spheres (HCS) with controllable diameter and shell thickness using a simple encapsulation pyrolysis synchronous deposition method is reported. This method changed the polystyrene spheres (PS), a widely used sacrifice hard template, into carbon by a pyrolysis and synchronous deposition process in the herm…
Abstract Hexagonal manganites belong to an exciting class of materials exhibiting strong interactions between a highly frustrated magnetic system, the ferroelectric polarization, and the lattice. The existence and mutual interaction of different magnetic ions (Mn and rare earth) results in complex magnetic phase diagr…
Temperature dependent analysis of electrical characteristics of multiferroics is an important tool to shed light on conduction mechanisms whose knowledge is vital for materials design with appropriate functionality. In this manuscript, we report on the effect of temperature on structural and electrical characteristics…
BACKGROUND: Due to the low water solubility of Docetaxel (DTX), it is formulated with ethanol and Tween 80 with lots of side effects. For this reason, special attention has been paid to formulate it in new drug nano-carriers. OBJECTIVE: The goal of this study was to evaluate the safety, antitumor activity and tissue d…
Combining organic synthesis with microscopy addresses long-standing bottlenecks in cyclocarbon production
Purpose is to determine regularities of the development of corrosive fatigue cracks in terms of high-strength drill pipes.
Water bridge dynamics between an atomic force microscopy (AFM) tip and a flat substrate is studied by using a multibody dissipative particle dynamics (MDPD) model. First, the numerical model is validated by comparing the present results of droplet contact angles and liquid bridges with those reported in the literature…
MgO films would naturally form on a magnesium alloy matrix in the air. They are loose and porous, and the corrosion resistance of magnesium alloys is limited. Here, we demonstrate that such a loose MgO film is not merely useless in the protection of magnesium alloys, as metallic atoms could penetrate the MgO film to f…
The comprehensive analyses of exciton states and absorption spectra from freestanding monolayer transition metal dichalcogenides such as ${\mathrm{MoS}}_{2}, {\mathrm{MoSe}}_{2}, {\mathrm{MoTe}}_{2}, {\mathrm{WS}}_{2}$, and ${\mathrm{WSe}}_{2}$ are theoretically presented in the Wannier\ensuremath{-}Mott exciton theor…
In this work, the penetration depth of a projectile with various geometries was analyzed using the cavity pressure method. The finite cavity method combines an analytical method and the finite element method and considers the deformation of the projectile only. This simulation method was implemented to ABAQUS/Explicit…
