In recent years, “green” nanomaterial synthesis methods that rely upon natural alternatives to industrial chemicals have been increasingly studied. Although the feasibility of synthesizing nanoparticles (NPs) using phytochemicals, carbohydrates, and other biomolecules is well established, environmental burdens of thes…
A series of tunable luminescence NaGdF4:Dy3+, Eu3+ nanophosphors have been synthesized for the first time by a one-step hydrothermal method. X-ray diffraction (XRD), field emission-scanning electron microscope (FE-SEM), X-ray energy dispersive spectrometer (EDS) and photoluminescence (PL) spectroscopy were employed to…
Silicene is a two‐dimensional structure composed of a buckled hexagonal honeycomb lattice of silicon atoms. Freestanding silicene is yet to be synthesized, but epitaxial silicene monolayers have been directly observed or predicted to exist on a number of supporting substrates. Herein the atomic and electronic structur…
A novel 3D networked graphene-ferromagnetic hybrid can be easily fabricated using one-step microwave irradiation. By incorporating this hybrid material into shape memory polymers, the synergistic effects of fast speed and the enhancement of thermal conductivity and mechanical stiffness can be achieved. This can be bro…
The structure of multilayer silicene formed on Ag(111) films was studied by low-energy electron diffraction. It turned out that the experimental data cannot be explained by proposed models that only consider buckling of silicon atoms. We have rather found that multilayer silicene on Ag(111) is actually a thin film of…
Magnetic nanoparticles (NPs) MnFe2O4 and Fe3O4 were stabilised by depositing an Al(OH)3 layer via a hydrolysis process. The particles displayed excellent colloidal stability in water and a high affinity to [(18)F]-fluoride and bisphosphonate groups. A high radiolabeling efficiency, 97% for (18)F-fluoride and 100% for…
Boronyl (BO) is a monovalent σ radical with a robust B≡O triple bond. Although BO/BO(-) are isovalent to CN/CN(-) and CO, the chemistry of boronyl has remained relatively unknown until recently, whereas CN/CN(-) and CO are well-known inorganic ligands. Further analogy may be established for BO versus H or Au ligands,…
We have computed the correlated electronic structure of FeSe and its dependence on the ${A}_{1g}$ mode versus compression. Using the self-consistent density functional theory-dynamical mean field theory (DFT-DMFT) with continuous time quantum Monte Carlo, we find that there is greatly enhanced coupling between some co…
Aluminate garnet phosphors Ca2GdZr2(AlO4)3:Ce(3+) (CGZA:Ce(3+)) for solid-state white lighting sources are reported. The crystal structure and Mulliken bonding population of the CGZA:Ce(3+) have been analyzed. The larger 5d ((2)D) barycenter shift εc and smaller phenomenological parameter 10Dq of Ce(3+) in CGZA are re…
A simple and efficient route to gold–polymer nanoparticle composites is described. Our versatile synthetic route exerts facile control over polymer nanoparticle morphology, including micelles, rod-like structures, and vesicles, all easily attainable from a single polymerization taken to different monomer conversions.…
Twinning is generally considered to be the primary deformation mechanism for hexagonal close-packed (hcp) metals due to their limited slip systems. Recent microcompression experiments point to strong size effects indicating that pyramidal slips can dominate in deformation under compression. We present analysis on the…
In this article, the rapid synthesis of colloidal, spherical polymer resins via enhanced copolymerization and polycondensation of resorcinol with formaldehyde is presented. The ultrasound-mediated technique assembles perfectly spherical resins in less than 5 min due to generated active species and free radicals produc…
We study the geometrically nonlinear behavior of uniformly compressed tensegrity prisms, through fully elastic and rigid--elastic models. The presented models predict a variety of mechanical behaviors in the regime of large displacements, including an extreme stiffening-type response, already known in the literature,…
In the search for phase change materials (PCM) that may rival traditional random access memory, a complete understanding of the amorphous to crystalline phase transition is required. For the well-known Ge2Sb2Te5 (GST) and GeTe (GT) chalcogenides, which display nucleation and growth dominated crystallization kinetics,…
We report a high-pressure experimental and theoretical investigation of the structural properties of zircon-type HoVO4. Angle-dispersive x-ray diffraction measurements were carried out under quasi-hydrostatic and partial non-hydrostatic conditions up to 28 and 23.7 GPa, respectively. In the first case, an irreversible…
Recent reports on the fabrication of phosphorene, i.e., mono- or few-layer black phosphorus, have raised exciting prospects of an outstanding two-dimensional (2D) material that exhibits excellent properties for nanodevice applications. Here we study by first-principles calculations the adsorption of CO, CO2, NH3, NO a…
We present a nano‐W dispersed polymer composite whose gamma attenuation is greatly enhanced. In situ pulverization and simultaneous encapsulation of polyethylene (PE) onto the nano‐W particles was successfully performed by ball milling. Adhesive encapsulation of PE was observed by means of interstitial diffusion of at…
We demonstrate the feasibility of superhydrophobic aligned nanocones as energy-effective frost-free coatings. Exemplified by Co(OH)2 nanocone films with condensed microdrop self-removal ability, their edge and whole-surface frosting time can be delayed to about 10 and 150 min, respectively. By using a Teflon gasket to…
Recent experimental results have demonstrated the ability of monolayer ${\mathrm{MoS}}_{2}$ to efficiently generate second harmonic fields with susceptibilities between 0.1 and 100 nm/V. However, few theoretical calculations exist with which to interpret these findings. In particular, it is of interest to theoreticall…
Nanotechnology exploits the enhanced reactivity of materials at the atomic scale to improve various applications for humankind. In agriculture, potential nanotechnology applications include crop protection and fertilization. However, such benefits could come with risks for the environment: non-target plants, plant-ben…
