With experimental results, we demonstrate the generation of high-order Laguerre-Gaussian modes with non-zero radial indices using a metal meta-surface, which is composed of a series of rectangle nanoholes with different orientation angles. The phase shift after transmission through the metasurface is determined by the…
Solid solution MAX phases offer the opportunity for further tuning of the thermomechanical and functional properties of MAX phases, increasing their envelope of performance. Previous experimental results show that the lattice parameters of ${\mathrm{Ti}}_{3}({\mathrm{Si}}_{x}{\mathrm{Al}}_{1\ensuremath{-}x}){\mathrm{C…
Dendrimers are hyper branched macro molecules with well-defined structure and high degree of functionality on the surface. The dendrimer architecture allows control over properties such as shape, size, density, polarity, reactivity, solubility etc. These special features can be exploited to design molecules having des…
To elucidate the persistent luminescence mechanism of the Ce3+-Cr3+-codoped Y3Al2Ga3O12 garnet (YAGG), the valence states of Ce and Cr ions before and during UV charging were investigated by X-ray absorption near edge structure (XANES) spectroscopy. In the XANES spectra for Ce LIII and Cr K edges of YAGG:Ce3+-Cr3+ und…
Graphene and other two-dimensional (2D) materials are of emerging interest as functional fillers in polymer-matrix composites. In this study, we present a multiscale atomistic-to-continuum approach for modeling interfacial stress transfer in graphene-high-density polyethylene (HDPE) nanocomposites. Via detailed charac…
Abstract Controlling the charges and spins of molecules lies at the heart of spintronics. A photoswitchable molecule consisting of two independent spins separated by a photoswitchable moiety was designed in the form of new ligand H 4 L, which features a dithienylethene photochromic unit and two lateral coordinating mo…
Abstract Titanium dioxide (TiO 2 ) is a white color additive that has a long history of global approval and use in food. There is, however, considerable confusion regarding the applicability of the biological effects of novel, engineered, nano‐sized forms of TiO 2 developed for nonpigmentary applications to the safety…
Because of their good behavior under irradiation, fuel elements based on U3Si2 particles dispersed in an Al matrix have been used to convert to low-enriched uranium in a large number of research reactors. This behavior is extended to any compound grown by interdiffusion between silicide and Al during the fabrication p…
Star-shaped molecules with three mutually immiscible arms self-assemble to form a variety of novel structures, with conformations that attempt to minimize interfacial area between the domains composed of the different arms. The geometric frustration caused by the joining of these arms at a common centre limits the siz…
The present work reports the influence of crosslink chemicals (vinyltrimethoxylsilane, dicumyl peroxide, and dibutyl dilaurate) on the mechanical strength and water absorption of the rice straw/high density polyethylene bio-composites. As revealed by the Fourier transform infrared spectra, the surface interaction betw…
A new type of atom‐thin carbon nanomesh clusters (CMCs) is prepared through a self‐sacrificial and morphology‐reserved thermal transformation of electrodeposited zinc coordination polymer (Zn‐CP). Such a unique structure can effectively inhibit the sheet stacking due to the self‐formed cluster morphology of Zn‐CP. The…
The described method enables facile gram‐scale preparation of CuFeS 2 nanocrystals exhibiting interesting thermoelectric properties from simple and readily available precursors. Exchange of primary organic ligands for inorganic ones using either (NH 4 ) 2 S or triethyloxonium tetrafuoroborate (Meerwein's salt) resulte…
The present preliminary study reports the synthesis of montmorillonite (MMT)/poly(o-toluidine) (PoTD) nanocomposites prepared by confining PoTD in the galleries of MMT. X-ray diffraction confirmed the intercalation of PoTD at 25°C, while exfoliation was observed at higher loading. UV–visible spectroscopy showed the va…
Materials science, as an interdisciplinary field with significant attention paid to nanoscience and nanotechnology in recent years, is generally concerned with the synthesis, atomic structure, chemical element distribution and various favorable properties of solid materials and structures. While solid-state processing…
A facile one-pot, bottom-up approach to construct composite materials of graphene and a pyrimidine-based porous-organic polymer (PyPOP), as host for immobilizing human hemoglobin (Hb) biofunctional molecules, is reported. The graphene was selected because of its excellent electrical conductivity, while the PyPOP was u…
Phase relations of magnesioferrite-magnetite solid solutions (Mg,Fe 2+ ) Fe23+ $\rm {Fe_{2}^{3+}}$ O 4 were investigated at pressures of 9–23 GPa and temperatures of 1200–1600 °C. Our new results indicate that the assemblage Mg 2 Fe 2 O 5 + Fe 2 O 3 reconstitutes to a hp-MgFe 2 O 4 phase at 20 GPa and 1300–1500 °C. Th…
When a semiflexible chain is confined in a narrow cylindrical tube, the formation of a polymer hairpin is a geometrical conformation that accompanies an exponentially large local free energy and, hence, is a relatively rare event. Numerical solutions of the hairpin distribution functions for persistence-length-to-tube…
Porous ZnO nanocrystalline films have drawn research attention due to improvement in gas sensing, adsorption, photocatalytic, and photovoltaic applications. However, scalable synthesis of porous nanostructures has been a challenge. Here, This paper reports a very easy, fast, and scalable one‐step process for synthesis…
This paper presents a feasibility study of a non-aqueous rechargeable battery based on aluminum and poly-(3,4-ethylenedioxythiophene) conductive polymer in a chloroaluminate ionic liquid. The polymer was electrodeposited on a vitreous carbon working electrode in a chloride aqueous solution and the structure was analyz…
This effort reports on novel fluorinated polyamide (FPA) and polyamide 1010 (PA1010)-based blends and graphene reinforced nanocomposite. PA1010/FPA (80:20) blend was opted as matrix material on the basis of molecular weight, thermal, and shear stress performance. Graphene was obtained through in situ chemical method o…
