The synthesis and characterization of a library of modular multifunctional polyesters with pendant functional groups are described. The polyesters were synthesized at room temperature by carbodiimide-mediated polymerization of pendant functionalized diols and succinic acid. The pendant groups are designed to mimic the…
We present measurements of thermal transport in 500-nm-thick, 35-$\ensuremath{\mu}$m-wide, and 806-$\ensuremath{\mu}$m-long micromachined suspended silicon nitride (Si-N) bridges over the temperature range of 77 to 325 K. The measured thermal conductivity of Si-N (for material grown by low-pressure chemical vapor depo…
The inhibition effect of Rhodanine-N-acetic acid (R-NA) on copper corrosion in acidic media is studied by using potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), and linear polarization resistance (LPR). The surface morphology is investigated by using scanning electron microscopy (SEM). The e…
PURPOSE: Intravenously (i.v.) administered nanomedicines have the potential for tumour targeting due to the enhanced permeability and retention (EPR) effect, but in vivo tumour models are rarely calibrated with respect to functional vascular permeability and/or mechanisms controlling intratumoural drug release. Here t…
Graphene-metal contacts have emerged as systems of paramount importance in the synthesis of high-quality and large-size patches of graphene and as vital components of nanotechnological devices. Herein, we study the accuracy of several density functional theory methods using van der Waals functionals or dispersive forc…
Highly reliable and bendable dielectrics are desired in flexible or bendable electronic devices for future applications. Hexagonal boron nitride (h-BN) can be used as bendable dielectric due to its wide band gap. Here, we fabricate high quality h-BN films with controllable thickness by a low pressure chemical vapor de…
Conformance assessment of rolling journals in a molecular bearing has been carried out with a combination of fullerenes and finite single-wall carbon nanotube molecules through quantitative analysis of the binding affinities. Endohedral fullerenes were applicable to three-body molecular bearings with slightly weaker b…
Dynamic dipolar toroidal response is demonstrated by an optical plasmonic metamaterial composed of double disks. This response with a hotspot of localized $E$-field concentration is a well-behaved toroidal cavity mode that exhibits a large Purcell factor due to its deep-subwavelength mode volume. All-optical Hall effe…
We present an electro-photo double modulation on the resistive switching behavior in an Au/BiFeO3/La0.7Sr0.3MnO3/SrTiO3 heterostructure, combining the electro-resistance effect and the photo-resistance effect. The pulse voltages can lead to nonvolatile resistance variations in this heterostructure, and the laser illum…
We determined the atomic structures and energies of 109\ifmmode^\circ\else\textdegree\fi{}, 180\ifmmode^\circ\else\textdegree\fi{}, and 71\ifmmode^\circ\else\textdegree\fi{} domain walls in ${\mathrm{BiFeO}}_{3}$, combining density functional $\mathrm{\text{theory}}+\mathrm{U}$ calculations and aberration-corrected tr…
This letter presents a level set-based topology optimization method that provides discrete cloaking configurations with superior performance. In some cases, the amount of light scattered around the two-dimensional cloaking structures is less than one-tenth that obtained in previous studies. Optimal configurations that…

Accelerated insertion of nanocomposites into advanced applications is predicated on the ability to perform a priori property predictions on the resulting materials. In this paper, a paradigm for the virtual design of spherical nanoparticle-filled polymers is demonstrated. A key component of this "Materials Genomics" a…
Materials with Pt@CeO2-δ core–shell nanoparticles on 3D-ordered macroporous (3DOM) CeO2 are prepared by in situ colloidal crystal templating. 3DOM Ptn@CeO2-δ/CeO2 catalysts, which have both good contact between the solid reactant and the catalyst and a high density of coordinatively unsaturated ceric sites, show high…
PURPOSE: To develop tablet formulations by adsorbing liquid self-emulsifying drug delivery systems (SEDDS) onto Neusilin®US2, a porous silicate. METHODS: Nine SEDDS were prepared by combining a medium chain monoglyceride, Capmul MCM EP, a medium chain triglyceride, Captex 355 EP/NF, or their mixtures with a surfactant…
We report the photoluminescence (PL) from graphene nanoribbons (GNRs) encapsulated in single-walled carbon nanotubes (SWCNTs). New PL spectral features originating from GNRs have been detected in the visible spectral range. PL peaks from GNRs have resonant character, and their positions depend on the ribbon geometrica…
We have prepared 2% Al doped ZnO (AZO) thin films on SrTiO3 (STO) and Al2O3 substrates by Pulsed Laser Deposition technique at various deposition temperatures (Tdep = 300 °C–600 °C). Transport and thermoelectric properties of AZO thin films were studied in low temperature range (300 K–600 K). AZO/STO films present sup…
In this study, we have investigated the structure–flame-retardant (FR) efficacy relationships of phosphoramidates (PRs) on flexible polyurethane foam (FPUF). FPUFs that contain model monosubstituted secondary PRs, monosubstituted tertiary PRs, and trisubstituted secondary PRs were prepared and evaluated for FR efficac…
Novel α-MnS hollow spheres (MHSs) have been fabricated successfully by a one-pot template-free solvothermal method. The as-synthesized α-MnS spheres have diameters of about 3-5 μm and porous shells of thickness about 0.5 μm composed of numerous nanocrystals. The samples were characterized by X-ray diffraction, scannin…
As comparable to the spherical nanocrystals, the nanocrystals with non-spherical shape have fascinating properties induced by a large fraction of under-coordinated atoms located at end parts, including edges, vertexes, and side facets. Herein, taking into account the shell-core configuration of semiconductor nanospher…
