Fundamental measure theory (FMT) for hard particles has great potential for predicting the phase behavior of colloidal and nanometric shapes. The modern versions of FMT are usually derived from the zero-dimensional limit, a system of at most one particle confined in a collection of cavities in the limit that all cavit…
Three kinds of amphiphilic copolymer, that is, poly(ε-caprolactone)-SS-poly(ethylene glycol) (PCL-SS-PEG), poly(ε-caprolactone)-polyethylenimine (PCL-PEI), and poly(ε-caprolactone)-polyethylenimine-folate (PCL-PEI-Fol) were synthesized and self-assembled into surface engineered hybrid nanoparticles (NPs). Morphologica…
We measured the acquisition of magnetic remanence of iron-nickel alloys (${\mathrm{Fe}}_{64}{\mathrm{Ni}}_{36}$, ${\mathrm{Fe}}_{58}{\mathrm{Ni}}_{42}$, and ${\mathrm{Fe}}_{50}{\mathrm{Ni}}_{50}$) and pure Ni under pressures up to 23 GPa at room temperature. Magnetization decreases markedly for ${\mathrm{Fe}}_{64}{\ma…
Only optically active excitons can be identified by transient absorption spectroscopy, and the actual mechanisms of exciton relaxation in nanoscale systems remain unknown as dipole-forbidden transitions and charge-transfer states are not accounted for. Focusing on interacting (6,4) and (8,4) carbon nanotubes (CNTs), w…
The electron-phonon coupling constant $(\ensuremath{\lambda})$ of carbon nanotubes $(\ensuremath{\lambda}=0.006)$ is much smaller than that of alkali-metal-doped ${\mathrm{C}}_{60}$ crystals $(\ensuremath{\lambda}=0.6)$. This difference may be due to the shape of the $\ensuremath{\pi}$-electron conjugated system: the…
An NMR-based approach for rapid characterization of translational diffusion of molecules has been developed. Unlike the conventional method of acquiring a series of 2D (13)C and (1)H spectra, the proposed approach involves a single 2D NMR spectrum, which can be acquired in minutes. Using this method, it was possible t…
Models of the amorphous phase of GeSbTe have been generated by density functional molecular dynamics simulations with the Becke–Lee–Yang–Parr (BLYP) exchange–correlation functional. Four independent 459-atom models have been used to improve the statistical analysis of the structural properties with respect to previous…
The biological solution small-angle X-ray scattering (BioSAXS) field has undergone tremendous development over recent decades. This means that increasingly complex biological questions can be addressed by the method. An intricate synergy between advances in hardware and software development, data collection and evalua…
Ferromagnetic shape memory alloys (FSMAs) and magnetic shape memory alloys (MSMAs) are metallic alloys that can undergo inelastic responses when exposed to magnetic fields. Several constitutive models have been proposed so far to model the behaviors of FSMAs. In this work, the effects of loading history on reorientati…
Abstract Surface‐enhanced Raman spectroscopy (SERS) has evolved from an esoteric physical phenomenon to a robust and effective analytical method recently. The need of addressing both the field enhancement and the extinction of nanoparticle suspensions, however, has been underappreciated despite its substantive impact…
We report an X-ray diffraction study and modeling of the structure of sodium silicate glasses and melts that are used as binders in the production of the latest generation of ceramic welding fluxes. Experimental data and reverse Monte Carlo (RMC) simulations results are analyzed in comparison with results for a sodium…
Herein, polypyridine (P 25 Py) is for the first time evaluated as an anode material for organic matter based electric energy storage devices. P 25 Py is synthesized both chemically and electrochemically and the influence of electrolyte and solvent on the doping behavior of the material is investigated in propylene car…
Abstract Pure powder and small single crystals of BaFe 2 S 2 O were obtained by solid‐state reaction between BaO, Fe, and S in closed silica ampoules. The crystal structure contains a magnetic ladderlike sublattice of high‐spin Fe 2+ (d 6 ) tetrahedrally coordinated by three S and one O atoms. Strong antiferromagnetic…
The present work reports a simple and easy wet chemistry synthesis of cuprous oxide (Cu2O) nanospheres at room temperature without surfactants and using different precursors. Structural characterization was carried out by X-ray diffraction, transmission electron microscopy, and scanning electron microscopy coupled wit…
We presented combinations of vapor phase transport (VPT) of mixture of methanol and acetone and thermal evaporation of brass (CuZn) which contain in-situ three stages in obtaining un-doped and Mn-doped zinc oxide (ZnO) nanostructures (NSs). The structure and morphology were characterized by energy dispersive X-ray ana…
In this paper we describe a prototype of a field effect transistor (FET) based on the Mott metal-insulator transition (MIT) in vanadium dioxide.It has been shown that increasing the modulation of the channel resistance, the gain of the field effect, and an increase of the amplification factor can be achieved by loweri…
We present a broadband and polarization-insensitive terahertz metamaterial absorber formed from double-layered same-sized patterned square patches on top of a metallic ground plane. The combination of the two same-sized metallic patches gives rise to an absorption bandwidth of 380 GHz with absorption over 90%. The ful…
We collect optical reflectivity data as a function of temperature across the structural tetragonal-to-orthorhombic phase transition at ${T}_{s}$ on ${\mathrm{Ba}(\mathrm{Fe}}_{1\ensuremath{-}x}{\mathrm{Co}}_{x}{)}_{2}{\mathrm{As}}_{2}$ for $x=0%$, 2.5%, and 4.5%, with uniaxial and in situ tunable applied pressure in o…
Nanodiamond has displayed some unique physical and chemical properties compared to bulk diamond, which broadens its applications in various areas. However, a more detailed picture of nanodiamond quantum confinements is still missing from a theoretical point of view. This investigation presents a study where the effect…
Solid-phase hydrogenation kinetics can be substantially increased by utilizing hydrogen spillover phenomenon. Carbonaceous allotropes are considered as promising spillover agents (SOAs) for improved hydrogen transport rate. We studied the effect of carbon-based SOA properties on irreversible hydrogenation. We divided…
