On axis holography by random particles encoding (2012)

A method for eliminating the unwanted terms in an on axis hologram is presented. In this method, free randomly distributed nanoparticles are in proximity to the object and their Brownian motion encodes the spatial features of the object in the recorded hologram. The nanoparticles are localized and a decoding pattern is calculated for each frame. This decoding pattern is then used to remove the reference beam and the conjugate beam in the reconstruction of the hologram.

Transport properties of ${\mathrm{Ba}}_{1\mathrm{\ensuremath{-}}\mathit{x}}$${\mathrm{K}}_{\mathit{x}}$${\mathrm{BiO}}_{3}$ and ${\mathrm{Nd}}_{2\mathrm{\ensuremath{-}}\mathit{x}}$${\mathrm{Ce}}_{\mathit{x}}$${\mathrm{CuO}}_{4}$ are calculated by solving the Boltzmann equation using the electronic energy-band structures obtained with the local-density full-potential linearized augmented-plane-wave method. For ${\mathrm{Ba}}_{1\mathrm{\ensuremath{-}}\mathit{x}}$${\mathrm{K}}_{\mathit{x}}$${\mathrm{BiO}}_{3}$ the calculated Hall coefficient ${\mathit{R}}_{\mathit{H}}$ is (two times) larger than experiment and has the correct (negative) sign. For ${\mathrm{Nd}}_{2\mathrm{\ensuremath{-}}\mathit{x}}$${\mathrm{Ce}}_{\mathit{x}}$${\mathrm{CuO}}_{4}$ a positive Hall coefficient is obtained for the magnetic field oriented perpendicular to the Cu-O planes. This is to be compared with a negative experimental value found for x0.18 and recent experiments that show a change of sign of this Hall coefficient (from negative to positive with increasing x) for x=0.18. These results indicate a trend (previously found for ${\mathrm{La}}_{2\mathrm{\ensuremath{-}}\mathit{x}}$${\mathrm{Sr}}_{\mathit{x}}$${\mathrm{CuO}}_{4}$) towards a regime in which the conventional band-theoretical description comes into better agreement with experiment. The highly anisotropic nature of the resistivity of ${\mathrm{Nd}}_{2\mathrm{\ensuremath{-}}\mathit{x}}$${\mathrm{Ce}}_{\mathit{x}}$${\mathrm{CuO}}_{4}$ is discussed.
Fuel Cell Systems for a Greener Aviation (2011)

The trend in new civil aircraft’s development is toward “more electric” aircraft and green sky. Fuel cell systems as possible part of the electrical supply in civil aircraft can allow reaching this target. Indeed fuel cell systems have high electrical efficiency, which can be used for on ground power generation and emergency power on flight, and are only producing water and oxygen depleted air as gas emissions. What it is also very innovative is that this “waste products” can be used to generate water on board and inert gas for the jet fuel tank as fire retardation and suppression measure. For several years the Institute of Technical Thermodynamics of the German Aerospace Centre (Deutsches Zentrum für Luft- und Raumfahrt; DLR) in cooperation with Airbus developed fuel cell systems which fulfil these functionalities for both aircraft ground and cruise operation. The main achievements of the last past years are the Antares-H2 development and tests as well as the successful milestones passed with the research aircraft DLR ATRA with fuel cell system test. This paper presents all the modelling and experimental activities of the DLR on fuel cell development for aircraft.
Synthesis of Carbocyclic Compounds via a Nickel-Catalyzed Carboiodination Reaction (2021)

A scalable nickel-catalyzed carboiodination reaction generating 6-membered carbocycles is reported. NiI2 and P(OEt)3, as the ligand and reducing agent, provided decorated iodo-tetrahydronaphthalenes in up to 94% yield. The impact of varying electronic and steric parameters on the reaction are reported and a non-linear Hammett plot was obtained, supporting a change in the rate-determining step from oxidative addition to reductive elimination. Experimental and DFT studies suggest that the malonate group may stabilize a nickel oxidative-addition complex. A variety of heteroatom-containing nucleophiles and medicinally relevant heterocycles were easily incorporated into the products via simple SN2 chemistry.
An asynchronous, single-chip, LMS based, adaptive fir echo canceller (1995)

An asynchronous, single-chip, high-speed communication adaptive echo canceller was developed during this research. Adaptation is based on the LMS algorithm with power-of-two convergence factor. Cancellation is performed by a 128-coefficient adaptive finite impulse response filter whose coefficients are updated every cycle. The LMS power-of-two update equations were modified to allow a pipelined implementation. Pipelining the adaptation and echo estimation operations enabled hardware minimization, a high sampling rate, and no increase in convergence time. The resulting circuit updates the filter coefficients and generates the output at a sampling rate greater than 205 kHz. The chip was designed using 0.8 mum CMOS standard cells. The single-chip layout requires a die size of 9.25 mm by 7.25 mm.
Mutual Complementarity between Diffusion-Type Flow Control and TCP (2006)

SUMMARY In current IP-based networks, the application of windowbased end-to-end flow control, including TCP, to ensure reliable flows is an essential factor. However, since such a flow control is provided by the end hosts, end-to-end control cannot be applied to decision-making in a time-scale shorter than the round-trip delay. We have previously proposed ad iffusion-type flow control mechanism to realize the extremely time sensitive flow control that is required for high-speed networks. In this mechanism, each network node manages its own traffic only on the basis of the local information directly available to it, by using predetermined rules. The implementation of decision-making at each node can lead to optimal performance for the whole network. Our previous studies showed that the mechanism works well, by itself, in high-speed networks. However, to apply this mechanism to actual networks, it needs to be able to coexist with other existing protocols. In this paper, we investigate the performance of diffusion-type flow control coexisting with TCP. We show that diffusiontype flow control can coexist with TCP and the two can be complementary. Then, we show that a combination of both controls achieves higher network performance than TCP alone in high-speed networks.
Demulsification of Heavy Crude Oil Emulsion Driven by Natural Materials (2023)

Abstract This study investigated the effectiveness of fly ash (FA) and extracted silica (SC) from sand as natural demulsifiers for breaking stable crude oil emulsions and spiltting oil-water into phases. A series of stable emulsion was formulated and the oil-water ratio was 4:6. Various concentrations of either FA or SC ranging from 0.25 – 1% were added into vials containing the prepared emulsions and demulsification test was conducted inside the oven at 70 °C. Rheology and interfacial tension characterizations were used to illustrate the demulsification mechanism of FA and SC demulsifiers. According to the experimental outcomes, the demulsification from the bottle test showed that water removal increased with the increasing FA concentration. The demulsification efficiency (DE) of 0.25, 0.5, 0.75, and 1% FA was 35.33%, 81.99%, 92.67% and 93.77%, respectively; within 150 minutes of demulsification duration while all the tested SC concentrations (0.25, 0.5, 0.75 and 1%) achived 90.11%, 93.87%, 95.89%, and 95.89%, respectively; under the same demulsification period. The reference sample (blank) only achieved DE of 14.76%. Rheological characterization showed that the incorporation of either FA or SC caused the reduction of emulsion viscosity which indicated the breaking of emulsion and separation of oil and water. The results from the interfacial tension measurments revealed that FA and SC could migrate and adsorb at oil-water interface. The addition of either FA or SC in the oil-water system led to a more drastic reduction in the interfacial tension as compared to the interfacial tension of oil-water system devoided of the FA and SC. The interfacial tensions of oil/water system in the presence of 0.25% and 1% FA were 18.91 mN/m and 14.85 mN/m, respectively, and that of 0.25% and 1% SC were 16.44 mN/m and 14.80 mN/m, respectively, after 200 seconds and that of blank sample was recorded to be 18.1 mN/m in the same duration.

Clickable Poly(ionic liquids): A Materials Platform for Transfection (2016)

Abstract The potential applications of cationic poly(ionic liquids) range from medicine to energy storage, and the development of efficient synthetic strategies to target innovative cationic building blocks is an important goal. A post‐polymerization click reaction is reported that provides facile access to trisaminocyclopropenium (TAC) ion‐functionalized macromolecules of various architectures, which are the first class of polyelectrolytes that bear a formal charge on carbon. Quantitative conversions of polymers comprising pendant or main‐chain secondary amines were observed for an array of TAC derivatives in three hours using near equimolar quantities of cyclopropenium chlorides. The resulting TAC polymers are biocompatible and efficient transfection agents. This robust, efficient, and orthogonal click reaction of an ionic liquid, which we term ClickabIL, allows straightforward screening of polymeric TAC derivatives. This platform provides a modular route to synthesize and study various properties of novel TAC‐based polymers.

Initial Validation of Robotic Operations for In-Space Assembly of a Large Solar Electric Propulsion Transport Vehicle (2017)

Developing a capability for the assembly of large space structures has the potential to increase the capabilities and performance of future space missions and spacecraft while reducing their cost. One such application is a megawatt-class solar electric propulsion (SEP) tug, representing a critical transportation ability for the NASA lunar, Mars, and solar system exploration missions. A series of robotic assembly experiments were recently completed at Langley Research Center (LaRC) that demonstrate most of the assembly steps for the SEP tug concept. The assembly experiments used a core set of robotic capabilities: long-reach manipulation and dexterous manipulation. This paper describes cross-cutting capabilities and technologies for in-space assembly (ISA), applies the ISA approach to a SEP tug, describes the design and development of two assembly demonstration concepts, and summarizes results of two sets of assembly experiments that validate the SEP tug assembly steps.
Diode-pumped solid state laser light sources for confocal laser scanning fluorescence microscopy (2008)

Diode-pumped solid-state lasers (DPSSLs) have been integrated as light sources in confocal laser scanning microscopy (CLSM). The standard argon ion laser at 488 nm is compared with a DPSSL operating at 473 nm in terms of noise and CLSM image characteristics. The equally high fluorescence image quality together with the many advantageous characteristics inherent to solid-state lasers suggests that excitation using a DPSSL is favored. The application of a dual-line DPSSL emitting at 491 and 532 nm for high resolution CLSM fluorescence imaging is shown for the first time.
I-DVFS: Instantaneous Frequency Switch During Dynamic Voltage and Frequency Scaling (2021)

This work presents I-DVFS: a novel approach to perform instantaneously the frequency switch during dynamic voltage frequency scaling (DVFS). The I-DVFS, unlike legacy DVFS, does not require halting an IPs execution to perform a DVFS transition, and thus, the performance overhead of DVFS is both reduced and more deterministic. Such attributes enable the more frequent use of DVFS and, thus, improve an IPs performance, power, and energy efficiency. Nonetheless, the overlapping of an IPs DVFS transition with the normal IPs execution creates a number of issues that need careful treatment at design time to ensure the reliable operation in the field. This article presents these issues and elucidates on how they are addressed in an implementation of I-DVFS that has been productized and can be found in millions of CPUs.
Microstrip-to-waveguide transition in planar form using a substrate integrated waveguide (2018)

Interconnection of waveguides or horn antennas to a printed circuit board (PCB) is still a challenge in modern system design. Currently, this requires high effort since the waveguide cannot easily be connected to a microstrip line or coplanar grounded waveguide. This paper introduces a new transition from microstrip to waveguide for the 24 GHz Industrial, Scientific and Medical (ISM) band, which facilitates mounting a WR-42 waveguide or horn antenna on a single substrate PCB with low manufacturing costs and hardware effort. The design, based on a new substrate integrated waveguide (SIW) to rectangular waveguide transition, as well as the simulated and measured results will be presented.
The amino acid sequence of delta haemolysin purified from a canine isolate of <i>S. aureus</i> (1984)

The amino acid sequence of a staphylococcal delta haemolysin purified from a canine isolate has been determined by a combination of chemical and mass spectroscopic sequence methods. The toxin molecule consists of 26 amino acids residues and is compared with the sequence of a delta haemolysin purified from a human isolate. The two sequences are found to be homologous although amino acid differences are observed in 9 of the 26 residues.
Determination of the Absolute Configurations of Chiral Alkanes – An Analysis of the Available Tools (2020)

Knowledge of absolute configurations (ACs) is crucial to understand the properties and functions of chiral molecules. Although the development of asymmetric reactions has enabled access to a large variety of enantioenriched compounds, stereochemical assignments of chiral molecules, especially chiral alkanes, remain challenging. In this Minireview, we first summarize common analytical techniques for AC determination with a focus on chiral alkanes as analytical targets. Next, we describe some of our efforts over the last 20 years on syntheses and AC determination of chiral alkanes including [123]tetramantane, hexadeuterated neopentane, and trans ‐perhydroazulene. Lastly, microscopic techniques and the crystalline sponge method are discussed as particularly promising approaches to revolutionize the field of stereochemical analysis.
Investigation of single and multidomain Pb(In0.5Nb0.5)O3–Pb(Mg1/3Nb2/3)O3–PbTiO3 crystals with mm2 symmetry (2010)

The piezoelectric properties of Pb(In(0.5)Nb(0.5))O(3)-Pb(Mg(1∕3)Nb(2∕3))O(3)-PbTiO(3) crystals with various engineered domain configurations were investigated. Rhombohedral and monoclinic∕orthorhombic crystals poled along their crystallographic [011] directions were found to possess macroscopic mm2 symmetry, with "2R" and "1O" domain, respectively. Crystals with the "2R" domain configuration were found to exhibit high extensional piezoelectric coefficients d(33) (∼1300 pC∕N) and d(32) (∼-1680 pC∕N), while crystals with the "1O" configuration possessed high shear coefficients d(15) (∼3500 pC∕N) and d(24) (∼2070 pC∕N), with relatively low extensional piezoelectric coefficients d(33) (∼340 pC∕N) and d(32) (∼-260 pC∕N). The observed results were explained by "polarization rotation" model, as related to their respective domain configurations.
Ceramic Processing Techniques for Catalyst Design: Formation, Properties, and Catalytic Example of ZSM‐5 on 3‐Dimensional Fiber Deposition Support Structures (2012)

Material science and catalysis play an important role in the chemical industry. Porous ceramics and metals are highly relevant in this field. There are plenty of applications for porous functional components, with engineered pores sizes ranging from micro to macro pores. A novel type of structured catalyst is introduced: support structures manufactured by three‐dimensional fiber deposition coated by a thin mordenite framework inverted type zeolite film. Surface coverage, homogeneity, and stability are evaluated. The effect of the design of the support structure on the catalytic activity will be studied in an environmental catalysis application, that is, the decomposition of nitrous oxide as a demonstrator.
[A case of familial sarcoidosis accompanied by Heerfordt syndrome with pericardial effusion]. (2010)

We found no cases of familial sarcoidosis with Heerfordt syndrome in the literature. A 25-year-old woman presented with high grade fever and parotid gland swelling in April 2004. An accompany with Right peripheral facial palsy developed in June, following which she was treated with corticosteroid therapy for 7 days, and her condition temporarily improved. Four months later she came to our hospital complaining of glare, then uveitis was diagnosed. She was referred to our department for work-up for treatment of sarcoidosis in January 2005. TBLB/BALF findings by bronchoscopy for definitive diagnosis were compatible with sarcoidosis. Various clinical symptoms indicated Heerfordt syndrome. Interestingly, pericardial effusion was also detected. In addition, her sister also suffers from sarcoidosis. Our patient had a favorable response to oral corticosteroid therapy (PSL 30 mg/day), gradually tapered 2.5-5 mg every 4 weeks, then stopped at the eighth month after commencing therapy. However, pulmonary lesions have relapsed 3 years after the discontinuation of the therapy. It is well known that relapses can happen when corticosteroids are used, and we should consider the progression of this disease and the indications of further treatment in this case.
Photoinduced Electron Transfer Pathways in Hydrogen-Evolving Reduced Graphene Oxide-Boosted Hybrid Nano-Bio Catalyst (2014)

Photocatalytic production of clean hydrogen fuels using water and sunlight has attracted remarkable attention due to the increasing global energy demand. Natural and synthetic dyes can be utilized to sensitize semiconductors for solar energy transformation using visible light. In this study, reduced graphene oxide (rGO) and a membrane protein bacteriorhodopsin (bR) were employed as building modules to harness visible light by a Pt/TiO2 nanocatalyst. Introduction of the rGO boosts the nano-bio catalyst performance that results in hydrogen production rates of approximately 11.24 mmol of H2 (μmol protein)(-1) h(-1). Photoelectrochemical measurements show a 9-fold increase in photocurrent density when TiO2 electrodes were modified with rGO and bR. Electron paramagnetic resonance and transient absorption spectroscopy demonstrate an interfacial charge transfer from the photoexcited rGO to the semiconductor under visible light.
Highly Proton Conductive Phosphoric Acid–Nonionic Surfactant Lyotropic Liquid Crystalline Mesophases and Application in Graphene Optical Modulators (2014)

Proton conducting gel electrolytes are very important components of clean energy devices. Phosphoric acid (PA, H(3)PO(4) · H2O) is one of the best proton conductors, but needs to be incorporated into some matrix for real device applications, such as into lyotropic liquid crystalline mesophases (LLCMs). Herein, we show that PA and nonionic surfactant (NS, C(12)H(25)(OCH(2)CH(2))(10)OH, C(12)E(10)) molecules self-assemble into PANS-LLCMs and display high proton conductivity. The content of the PANS-LLCM can be as high 75% H(3)PO(4) · H2O and 25% 10-lauryl ether (C(12)H(25)(OCH(2)CH(2))(10)OH, C(12)E(10)), and the mesophase follows the usual LLC trend, bicontinuous cubic (V1)-normal hexagonal (H1)-micelle cubic (I1), by increasing the PA concentration in the media. The PANS-LLCMs are stable under ambient conditions, as well as at high (up to 130 °C) and low (-100 °C) temperatures with a high proton conductivity, in the range of 10(-2) to 10(-6) S/cm. The mesophase becomes a mesostructured solid with decent proton conductivity below -100 °C. The mesophase can be used in many applications as a proton-conducting media as well as a phosphate source for the synthesis of various metal phosphates. As an application, we demonstrate a graphene-based optical modulator using supercapacitor structure formed by graphene electrodes and a PANS electrolyte. A PANS-LLC electrolyte-based supercapacitor enables efficient optical modulation of graphene electrodes over a range of wavelengths, from 500 nm to 2 μm, under ambient conditions.
