The uranium(IV) terminal oxo species Tp*(2)U(O) has been synthesized by oxygen-atom transfer from pyridine-N-oxide to Tp*(2)U(2,2'-bipyridine), a trivalent uranium species with a monoanionic bipyridine ligand. Full characterization of the oxo species using (1)H NMR and IR spectroscopies, X-ray crystallography, and com…
Solid state crystal structures are discussed and compared for all seven members of the indenocorannulene family that have been recently synthesized by iterative microwave-assisted intramolecular arylations and characterized by single crystal X-ray diffraction. These bowl-shaped polyaromatic hydrocarbons include monoin…
In this research, the condition for uniform lighting generated by array of LEDs with large view angle was studied. The luminous intensity distribution of LED is not monotone decreasing with view angle. A LED with freeform lens was designed as an example for analysis. In a system based on LEDs designed in house with a…
Abstract Fabrication of organic field‐effect transistors (OFETs) using a high‐throughput printing process has garnered tremendous interest for realizing low‐cost and large‐area flexible electronic devices. Printing of organic semiconductors for active layer of transistor is one of the most critical steps for achieving…
The term 'nanoclay' generically refers to the natural clay mineral, montmorillonite, with silica and alumina as the dominant constituents. The incorporation of nanoclays into polymeric systems dramatically enhances their barrier properties as well as their thermal and mechanical resistance. Consequently, nanoclays are…
We review recent efforts to detect small numbers of nuclear spins using magnetic resonance force microscopy. Magnetic resonance force microscopy (MRFM) is a scanning probe technique that relies on the mechanical measurement of the weak magnetic force between a microscopic magnet and the magnetic moments in a sample. S…
In order to explore the reason why the single-layered cuprates, ${\mathrm{La}}_{2\ensuremath{-}x}(\mathrm{Sr}/\mathrm{Ba}{)}_{x}{\mathrm{CuO}}_{4}$ (${T}_{c}\ensuremath{\simeq}40\text{ }\text{ }\mathrm{K}$) and ${\mathrm{HgBa}}_{2}{\mathrm{CuO}}_{4+\ensuremath{\delta}}$ (${T}_{c}\ensuremath{\simeq}90\text{ }\text{ }\m…
It is noticeable that porous architectural characteristics of the biomaterials play an important role in revascularization of the scaffold. However, there has been no consensus regarding the optimal conditions for vascularization, including macropore size, shape, interconnection, and the arrangement of macropores, due…
Stem cells are of widespread interest in regenerative medicine due to their capability of self-renewal and differentiation, which is regulated by their three-dimensional microenvironment. In this study, a computer-aided biofabrication technique based on laser-induced forward transfer (LIFT) is used to generate grafts…
A simple and straightforward method combines microwave-assisted solvothermal conditions with the coordination modulation method to achieve the size-controlled formation of the porous coordination polymer (PCP), [Cu 3 (btc) 2 ] (where btc represents benzene-1,3,5-tricarboxylate) in the nano/micro regimes. The addition…
Disordered nanocomposites comprised of polyethylene oxide and exfoliated MoS2 are cycled in the voltage range of 0.01−3.0 V. The nanocomposites showed a significant increase in reversible capacity and cycle stability when compared to exfoliated or bulk MoS2 and may be used as anode material in lithium ion batteries.
Recent processing activities at the Savannah River Site (SRS) involved purifying neptunium solutions using anion exchange (ReillexTM HPQ resin) columns. The addition of cooling coils and the use of antifreeze in a chemical make-up tank led to an evaluation of chemical incompatibility accident scenarios between the ant…
Ba2Ca(BO3)2: Eu2+ green phosphors were prepared by sol-gel process. The crystallization processes of the phosphor precursors were characterized by X-ray diffraction (XRD) and thermogravimetric analysis (TG). The photoluminescence (PL) results showed that this phosphor was efficiently excited by ultraviolet (UV)-visibl…
Small scale explosions, using a detonator, of 7075 aluminium alloy cylinders, 15–100 mm outside diameter, were carried out to investigate the effects of heat treatment on fragmentation. This was the finest for the strongest as received alloy and coarsest for the softest overaged alloy. This effect was similar to that…
The title compound, [Ag(C(27)H(23)BrN(3)O(4))(CH(3)CN)(2)](PF(6))(2), is a mononuclear salt species in which the silver(I) atom is coordinated by one ligand and two acetonitrile mol-ecules and exhibits a distorted T-shaped coordination. The asymmetric unit contains one independent cation and two independent hexa-fluor…
Abstract The purpose of this study was to evaluate the in vitro characteristics of poly(lactic acid‐co‐lysine) arginine–glycine–aspartic acid (PLA–PLL–RGD) nanoparticles (NPs) loaded with mitoxantrone. PLA–PLL–RGD NPs with a particle size of 200 nm were prepared with a modified emulsification solvent‐diffusion method.…
We report the large-scale assembly of type-switchable field effect transistors (FETs) based on carbon nanotubes (CNTs) and nanoparticles (NPs). In this device, the charges stored in NPs adjacent to ambipolar CNT channels were adjusted to control the carrier type and density in the channels. We demonstrated the real-ti…
ZrB2, YAG, and Al2O3 are widely applied because of some excellent performance qualities, but ZrB2 is easily oxidized in high-temperature air. To make the ZrB2 ceramics obtain better oxidation resistance, high-density ZrB2–YAG–Al2O3 ceramics were prepared. The oxidation behavior of ZrB2–YAG–Al2O3 ceramics was investiga…
A method is developed for calculating the small-angle x-ray scattering originating from within the interior of a thin film under grazing incidence illumination. This offers the possibility of using x-ray scattering to probe how the structure of polymers is modified by confinement. When the diffuse scattering from a th…
Lead-free 0.95 K0.5Na0.5NbO3-0.05LiSbO3 (KNN-LS) ceramics doped with 0.2 mol% BiMnO3 (BM) have been prepared by the conventional mixed-oxide technique, with sintering temperature at 1095–1120°C. Microstructural and compositional analyses of these doped ceramics have been carried out using X-ray diffraction (XRD) and s…
