Marius Steigmann, DDS/Alberto Monje, DDS/Hsun-Liang Chan, DDS, MS/Hom-Lay Wang, DDS, MS, PhD: One of the most challenging tasks in implant dentistry is to fulfill the esthetic expectations of patients. While implant positioning and adequate amounts of soft and hard tissues are essential for achieving an esthetic outco…
A new and faster Total Monte Carlo (TMC) method for the propagation of nuclear data uncertainties in Monte Carlo nuclear simulations is presented (the fast TMC method). It addresses the main drawback of the original TMC method, namely, the necessary large time multiplication factor compared to a single calculation. Wi…
We describe a novel cell used to combine in situ transmission X-ray absorption spectroscopy (XAS) with diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) in a single experiment. The novelty of the cell design compared to current examples is that both radiations are passed through an X-ray and IR tran…
Abstract Ausreichend leistungsfähige Primärsprengstoffe wie Bleiazid basieren oft auf giftigen Schwermetallen, die es zu ersetzen gilt. Eine neue potenziell geeignete Verbindung, Dikalium‐1,1′‐dinitramino‐5,5′‐bistetrazolat (K2DNABT), wurde ausgehend von Dimethylcarbonat, Hydrazin und Glyoxal hergestellt und chemisch…
Abstract Compared to organic light‐emitting diodes, solid‐state light‐emitting electrochemical cells (LECs) exhibit advantages of simple device structures, low operation voltages, and compatibility with air‐stable metal electrodes. Since the first demonstration of white LECs in 1997, the cells have been studied extens…
The effect of lithium (Li) on the development of pegmatitic textures was evaluated experimentally at H 2 O-saturated and H 2 O-undersaturated conditions at 500 MPa pressure and temperatures ranging from 400 to 800 °C. The addition of ~3700 ppm Li to a starting material of common granitic composition (Lake County obsid…
We have designed interlayer grating couplers with single/double metallic reflectors for Si/SiO(2)/SiN multilayer material platform. Out-of-plane diffractive grating couplers separated by 1.6 μm thick buffer SiO(2) layer are vertically stacked against each other in Si and SiN layers. Geometrical optimization using gene…
Various metal-doped p-type CaFe2O4 photocathodes were prepared in an attempt to improve the low quantum efficiency for photoreaction. CuO and Au doping enhanced the photocurrent by expansion of the absorption wavelength region and plasmon resonance, respectively. X-ray diffraction (XRD) and X-ray absorption fine struc…
In this work, we demonstrate that composite spoof surface plasmon polaritons can be excited by coplanar waveguide, which are composed of two different spoof surface plasmon polaritons (SSPPs) modes propagating along a periodically corrugated metallic thin film simultaneously. These two SSPPs correspond to the dominant…
To assess the effectiveness of the strategies implemented in the European Union (EU) to control Classical scrapie (CS), epidemiological data have been compared in the context of the efforts in terms of control measures applied over time. Official EU surveillance data and results from questionnaire surveys of EU Member…
We report a first-principles molecular dynamics study of the equation of state, structural, and elastic properties of MgSiO 3 glass at 300 K as a function of pressure up to 170 GPa. We explore two different compression paths: cold compression, in which the zero pressure quenched glass is compressed at 300 K, and hot c…
A new type of smart borinic acid polymer with luminescence and multiple stimuli-responsive properties is reported. In DMSO with small amounts of water, the homopolymer PBA shows a tunable upper critical solution temperature (UCST). As the amount of water increases from 0 to 2.5 % (v/v), the UCST rises linearly from 20…
Recent results from an ITPA joint experiment to study the onset, growth, and decay of relativistic electrons (REs) indicate that loss mechanisms other than collisional damping may play a dominant role in the dynamics of the RE population, even during the quiescent Ip flattop. Understanding the physics of RE growth and…
In this work, the synthesis and characterization of multifunctional crumpled graphene-based ternary nanocomposite photocatalysts for advanced water treatment applications is described. Currently, a major hurdle for the scale-up and optimization of aqueous, graphene-based photocatalysts is restacking of graphene nanosh…
Recent progress in developing various strategies for exploiting efficient MPA fluorophores for two emerging technological MPA applications including frequency upconversion photoluminescence and lasing as well as 2PA fluorescence bioimaging and biosensing are presented. An intriguing application of MPA frequency-upconv…
Shape-controlled Pt nanoparticles (cubic, tetrahedral, and cuboctahedral) are synthesized using stabilizers and capping agents. The nanoparticles are cleaned thoroughly and electrochemically characterized in acidic (0.5 M H2SO4 and 0.1 M HClO4) and alkaline (0.1 M NaOH) electrolytes, and their features are compared to…
Voltage sag remains a serious power-quality (PQ) problem by being the most common and causing more economic losses. The dynamic voltage restorer (DVR) is a definitive solution to address the voltage-related PQ problems. Conventional topologies operate with a dc link, which makes them bulkier and costlier; it also impo…
The photovoltaic performance and charge generation dynamics in thin film bulk heterojunction organic photovoltaic (BHJ OPV) devices comprising the small molecule donor 7,7′-(4,4-bis(2-ethylhexyl)-4H-silolo[3,2-b:4,5-b′]dithiophene-2,6-diyl)bis(6-fluoro-4-(5′-hexyl-[2,2′-bithiophen]-5-yl)benzo[c][1,2,5]thiadiazole) (p-…
The successful synthesis of a threefold symmetric C78H36 molecule with 22 fused benzene rings is reported. This clover-shaped nanographene was characterized on an ultrathin insulating film with atomic resolution by scanning probe microscopy.
BACKGROUND: Graphene oxide (GO) is a single layer carbon sheet with a thickness of less than 1 nm. GO has good dispersibility due to surface modifications with numerous functional groups. Reduced graphene oxide (RGO) is produced via the reduction of GO, and has lower dispersibility. We examined the bioactivity of GO a…
