A new diagnostic technique was developed to produce high-resolution impurity transport measurements of the steep-gradient edge of fusion plasmas. Perturbative impurity transport measurements were performed for the first time in the NSTX plasma edge ( r / a ∼ 0.6 to the SOL) with short neon gas puffs, and the resulting…
Cryo electron tomography is a technique that allows visualization of biological specimens in three dimensions with nanometer resolution. For cryo immobilized life sciences samples it can reveal cellular morphology, the shape of membranous structures, and depict internal macromolecular arrangements and large proteins.…
High-quality-factor room-temperature light-emitting diodes based on Ge self-assembled quantum dots are successfully fabricated by employing a lateral p–i–n diode structure and a modified L3-type photonic crystal nanocavity. Sharp resonant peaks with Q-factor larger than 800, corresponding to the cavity modes, are clea…
The aim of this work is to improve the select mechanical properties of keratin films for biomedical application by exploiting the hierarchical cell structure of wool fibers in a simple and green process. Bio-composite keratin films were prepared by ultrasonic irradiation of wool fibers soaked in clean water, have prev…
Binuclear ruthenium(III) complexes [RuX3L]2 · nH2O (X = Cl, L = L1, L2, L3; n = 1, L4 and L5, X = Br; L = L3), [RuX3L1.5]2 · nH2O (X = Br, L = L1; n = 0, L4; n = 6 and L5; n = 10), and [RuX3L2]2 (X = Br, L = L2) have been isolated by treatment of hydrated RuX3 (X = Cl/Br) in acetone with 2-(2′-aminophenylbenzimidazole…
Nonlinear numerical simulations are reported for a conventional unitized laminated glass curtain wall subjected to high- and low-level air blast loading. The studied curtain wall, spanning floor to floor, consisted of a laminated glass panel, a continuous bead of structural silicone sealant, a split screw spline frame…
(Ag,Cu)(In,Ga)Se2alloy absorber layers with various Ga/(Ga+In) and Ag/(Ag+Cu) ratios were deposited using multisource elemental evaporation and analyzed by glancing incidence X-ray diffraction and energy dispersive X-ray spectroscopy. All films exhibit chalcopyrite reflections in the X-ray diffraction pattern and film…
A perturbation theory is used to calculate bcc solid-liquid interfacial free energies of metallic systems with embedded-atom model potentials. As a reference system for bcc crystals we used a single-occupancy cell, hard-sphere bcc system. Good agreements between the perturbation theory results and the corresponding re…
The origin of spin-dimerization and concomitant spin-gap opening in the triclinic phase of poly- and single-crystalline La${}_{2}$RuO${}_{5}$ at unusually high temperatures was investigated using magnetic susceptibility and specific-heat measurements. From the low-temperature crystal structure the formation of antifer…
A two-step growth method, namely, initial crystallization from pentacene monolayer grains to nanosized single crystals (nanocrystals) and subsequent physical vapor transport (PVT) growth on the nanocrystals as seeds, is demonstrated to fabricate larger microsized pentacene single crystals. The pentacene monolayer film…
The goal of sustainable water splitting is to generate hydrogen and oxygen from water using only renewable energy inputs. The hydrogen can then be stored and recombined with oxygen later, giving energy and water as the only products. Hence water splitting can be seen as an environmentally friendly way of turning inter…
Three new 2D copper(ii) complexes [Cu(NIPH)(L)] (1), [Cu(BDC)(L)(H2O)] (2), and [Cu(HBTC)(L)]·2H2O (3) were hydrothermally synthesized by self-assembly of aromatic polycarboxylates (H2NIPH = 5-nitroisophthalic acid, H2BDC = 1,3-benzenedicarboxylic acid, H3BTC = 1,3,5-benzenetricarboxylic acid) and the flexible bis(pyr…
Abstract Platinum nanoparticles were fabricated on multiwalled carbon nanotubes (MWCNTs) by using supercritical fluid deposition. In this technique, deposition was carried out in a supercritical carbon dioxide fluid via hydrogen reduction of a dissolved platinum complex. The deposition temperature and deposition‐time…
Purpose No one particular fluid has cooling and lubrication properties suitable for every metalworking application. The purpose of this paper is first, to investigate the effect of anionic and nonionic mixed emulsifier system in stabilization of cutting fluid formulations and second, to study the interaction synergism…
Pharmacokinetic modeling of dynamic contrast-enhanced (DCE) MRI data provides measures of the extracellular-extravascular volume fraction (v(e) ) and the volume transfer constant (K(trans) ) in a given tissue. These parameter estimates may be biased, however, by confounding issues such as contrast agent and tissue wat…
We optimized Ag/ZnO back reflectors (BR) for hydrogenated nanocrystalline silicon (nc-Si:H) solar cells by independently changing the textures of the Ag and ZnO layers. We found that Ag/ZnO with textured Ag and thin ZnO provides the highest nc-Si:H solar cell efficiency. Optimized Ag texture with an rms = 40 nm effect…
A series of phosphate based glasses of composition 45 P 2 O 5 –(40− x ) CaO –15 Na 2 O – x ZnO ( x = 0, 3, 6, 8 10, and 12 mol%) were prepared employing melt‐quenching techniques. Based on the thermal analysis data of glasses, the schedule of thermal treatments have been designed and employed to obtain their glass cer…
Abstract Triple‐shell architectures, consisting of poly[(N,N‐diethylaminoethyl methacrylate)‐block‐(N‐vinylcaprolactam)‐block‐(N,N‐dimethylaminoethyl methacrylate)] triblock copolymers, are obtained by sequential reversible addition–fragmentation chain transfer polymerizations, using a terminal‐modified hyperbranched…
Cobalt-silver (Co-Ag) core-shell nanoparticles with different silver thicknesses were prepared by the microemulsion method in a two-step reduction process. Transmission electron microscopy (TEM) characterization revealed the almost monodispersity and nanometric size (in the range 3-5 nm depending on the shell thicknes…
