Heterogeneous nucleation characteristics of mixed vapor of benzene and cyclohexane on a cold substrate. (1993)

The heterogeneous phase transition of mixed benzene and cydohexane vapors on a cold copper substrate was observed by slowly cooling the substrate under reduced pressure conditions. In the conversion of the vapor to the condensed phase, vapor-to-liquid or vapor-to-solid phase transitions occurred depending on the mixing ratio of both vapors. By measuring the critical vapor pressure and temperature, corresponding critical supersaturation ratios were determined for various mixing ratios of both vapors. The critical pressure for the formation of solid benzene from mixed vapor agreed closely with that of pure vapor having higher composition. The critical pressure for the formation of solid cyclohexane from mixed vapor decreased from 6 to 9% compared with that from pure vapor. Liquid condensate was formed at critical supersaturation ratios of almost unity. A phase diagram was constructed by solving a non-linear simultaneous equation derived from vapor-liquid equilibrium and critical pressure-temperature relationships. It agreed in a practical sense with the observed results.

On identifying the aging mechanisms in li-ion batteries using two points measurements (2017)

Lithium-ion batteries are prone to aging, which decreases the battery performance. The term battery State of Health (SOH) is widely used to describe many different aspects of battery performance. One critical aging characteristic is the loss of cyclable energy quantified by the decrease in capacity. Algorithms that estimate the capacity fade using voltage measurements are widely published in literature and are commonly used in commercial Battery Management Systems (BMS). However, there are fewer studies identifying the aging mechanisms, such as the loss of cyclable lithium, or the loss of active material, both of which manifest as capacity fade. Furthermore, many of these algorithms require voltage measurement data acquired during a full charge or discharge cycle, which is inconvenient to obtain while the battery is in use. In the following, we present a methodology to identify the aging mechanisms by changes in the capacity of active material in each electrode, and the changes in the stoichiometric operating window of the half-cell potentials. The proposed method utilizes measurement obtained from only two operating points, with no requirement on a constant current while traversing between these two operating points. The method is tested via simulating the LiFePO4 (LFP) chemistry, where identification is particularly difficult due to its flat voltage characteristics. Furthermore, unlike previously presented methods, the identifiability of the aging mechanisms is studied with respect to location of the two operating points in the voltage curve. It is important to note that the techniques explored and proposed in this paper rely on opportunistic measurements of terminal voltage after a rest period due to its reliance on the invariant characteristic of the half-cell potentials.
Influence of Hydrodynamic Conditions on Quantitative Cellular Assays in Microfluidic Systems (2007)

This study demonstrates the importance of the hydrodynamic environment in microfluidic systems in quantitative cellular assays using live cells. Commonly applied flow conditions used in microfluidics were evaluated using the quantitative intracellular Ca2+ analysis of Chinese hamster ovary (CHO) cells as a model system. Above certain thresholds of shear stress, hydrodynamically induced intracellular Ca2+ fluxes were observed which mimic the responses induced by chemical stimuli, such as the agonist uridine 5'-triphosphate tris salt (UTP). This effect is of significance given the increasing application of microfluidic devices in high-throughput cellular analysis for biophysical applications and pharmacological screening.
Bend-optimized dispersion-shifted single-mode designs (1985)

A bend-optimized design for a dispersion-shifted single-mode fiber with segmented-core profile is described. With this design, dispersion-shifted fibers having the highest cutoff wavelengths reported to date have been achieved. Results on dispersion, attenuation, mode radius, bending, and microbending loss for such fibers are presented and compared to alternate designs.
Broadly tunable parametric generation of ultrashort pulses (1994)

Negative feedback-controlled, mode-locked Nd:YAG or Nd:YLF lasers are attractive pump sources for parametric oscillators (OPO) 1,2 because of their exceptional stability, and extended pulse train and the short duration of the pulses. In this work we demonstrate effective parametric compression down to 600 fs in a simple synchronously pumped linear cavity OPO using a KTP crystal. As pump source, the active-passive, mode-locked Nd:YAG laser with passive-negative feedback was used (Continuum model PY-61C-10). This laser generated stable (less than ± 0.2% pulse to pulse fluctuation) picosecond pulse trains of 600 ns (85 pulses) with energy of 4.7 mJ at a repetition rate of 10 Hz. A minimum pulse duration of 9.5–10 ps is achieved after an initial transient of 7–10 roundtrips in the laser cavity. The pulse duration increases after the first 200 ns to reach a maximum of 13–15 ps towards the end of the train. The OPO crystal is pumped through a 1-m focal distance lens by the second harmonic of this source, generated in a 6-mm-long KTP crystal. The OPO cavity, resonant for the idler only, was formed by two flat mirrors: Al-coated and dielectric output mirror (R ≈ 50% between 1.2 and 3 μm). We used a noncollinear scheme for parametric interaction, with an angle between pump beam and optical cavity axis of ≈ 3°). As nonlinear OPO element 14-mm and 6-mm-length KTP crystals cut at θ = 54° and ϕ = 0°, and θ = 90° and ϕ = 23.5°, respectively, were used.
Preparation, surface and colloidal properties of (vinyl acetate‐butylacrylate) copolymer latexes‐effect of emulsion polymerization process and copolymer composition (1981)

Abstract The effects of comonomer composition and the method of monomer addition on the compositional homogeneity and the colloidal properties of (vinyl acetate‐butyl acrylate) copolymer latexes were investigated. Particle size and distribution, and the surface characteristics of the copolymer latexes were found to vary with the comonomer composition and the type of the polymerization process. The aging of the latexes affects the surface properties and by that the colloidal stability against electrolytes. Branching, hydrolysis, flexibility of the molecules and heterogeneity of the latex particles appear to play a major role for the stability of the latexes.
Conversion to Graves disease from Hashimoto thyroiditis: a study of 24 patients (2018)

To our knowledge, large series documenting the conversion of HT to GD are scarce. Although rare, this phenomenon should not be misdiagnosed. Suspicion should be raised whenever thyroxine posology must be tapered down during the follow-up of HT patients. Further immunological and genetic studies are needed to explain this unusual autoimmune change.
Emergence of Influenza Viruses and Crossing the Species Barrier (2013)

ABSTRACT Influenza A viruses are zoonotic pathogens that infect a variety of host species including wild aquatic birds, domestic poultry, and a limited number of mammals including humans. The error-prone nature of the virus's replication machinery and its ability to transmit among multiple hosts lead to generation of novel virus variants with altered pathogenicity and virulence. Spatial, molecular, and physiological barriers inhibit cross-species infections, particularly in the case of human infection with avian viruses. Pigs are proposed as a mixing vessel that facilitates movement of avian viruses from the wild bird reservoir into humans. However, the past decade has witnessed the emergence of highly pathogenic and virulent avian H5 and H7 viruses that have breached these barriers, bypassed the pig intermediate host, and infected humans with a high mortality rate, but have not established human-to-human transmissible lineages. Because influenza viruses pose a significant risk to both human and animal health, it is becoming increasingly important to attempt to predict their identities and pathogenic potential before their widespread emergence. Surveillance of the wild bird reservoir, molecular characterization and documentation of currently circulating viruses in humans and animals, and a comprehensive risk assessment analysis of individual isolates should remain a high priority. Such efforts are critical to the pursuit of prevention and control strategies, including vaccine development and assessment of antiviral susceptibility, that will have a direct impact on the well-being of humans and animals worldwide.
Spectroscopic ellipsometry studies of I-IF treated Si (100) surfaces (2001)

Both ex situ and in situ spectroscopic ellipsometry (SE) measurements have been employed to investigate the effects of HF cleaning on Si surfaces. The hydrogeniterminated (H-terminated) Si surface was modeled as an equivalent dielectric layer, and monitored in real time by SE measurements. The SE analyses indicate that after a 20-s 9:l HF dip without rinse, the Si ( 100) surface was passivated by the hydrogen termination and remained chemically stable. Roughness of the HF-etched bare Si (100) surface was observed, in an ultrahigh vacuum (UHV) chamber, and analyzed by the in situ SE. Evidence for desorption of the H-terminated Si surface-layer, after being heated to 550 “C in the UHV chamber, is presented and discussed. This is the tirst use of an ex situ and in situ real-time, nondestructive technique capable of showing state of passivation, the rate of reoxidation, and the surface roughness of the H-terminated Si surfaces.

Second-Sphere Lattice Effects in Copper and Iron Zeolite Catalysis (2022)

Transition-metal-exchanged zeolites perform remarkable chemical reactions from low-temperature methane to methanol oxidation to selective reduction of NOx pollutants. As with metalloenzymes, metallozeolites have impressive reactivities that are controlled in part by interactions outside the immediate coordination sphere. These second-sphere effects include activating a metal site through enforcing an "entatic" state, controlling binding and access to the metal site with pockets and channels, and directing radical rebound vs cage escape. This review explores these effects with emphasis placed on but not limited to the selective oxidation of methane to methanol with a focus on copper and iron active sites, although other transition-metal-ion zeolite reactions are also explored. While the actual active-site geometric and electronic structures are different in the copper and iron metallozeolites compared to the metalloenzymes, their second-sphere interactions with the lattice or the protein environments are found to have strong parallels that contribute to their high activity and selectivity.
Analysis and control to the ultra-low frequency oscillation in southwest power grid of China: A case study (2018)

The ultra-low frequency oscillations(ULFO) are found in the future Southwest Power Grid under some faults, which will asynchronously interconnect with the State Grid via the HVDC and VSC-HVDC before the end of 2018. In this paper, the phenomenon of ULFO in the asynchronous interconnected Southwest Power Grid is introduced. And then, with the oscillation energy flow and the amplitude-phase analysis for the ULFO, the energy characteristics of each power plant participating in ULFO are revealed, i.e., the ULFO are mainly between the hydropower plants and the thermal power plants. Furthermore, with the analysis of damping characteristics of main hydropower plants, the cause of the ULFO, i.e., lacking of damping in the hydropower plant is revealed. Upon the above results, an example of suppressing the ULFO with the approach of control parameters tuning for the governor of the dominant generators is presented.

Minimum Cost Distributed Source Coding Over a Network (2010)

This paper considers the problem of transmitting multiple compressible sources over a network at minimum cost. The aim is to find the optimal rates at which the sources should be compressed and the network flows using which they should be transmitted so that the cost of the transmission is minimal. We consider networks with capacity constraints and linear cost functions. The problem is complicated by the fact that the description of the feasible rate region of distributed source coding problems typically has a number of constraints that is exponential in the number of sources. This renders general purpose solvers inefficient. We present a framework in which these problems can be solved efficiently by exploiting the structure of the feasible rate regions coupled with dual decomposition and optimization techniques such as the subgradient method and the proximal bundle method.
Efficient Ammonia Decomposition in a Catalytic Membrane Reactor To Enable Hydrogen Storage and Utilization (2019)

Liquid ammonia is a high density (17.7 wt. %) hydrogen carrier with a well-established production and distribution infrastructure. Efficient decomposition and purification are essential for its use as a hydrogen storage material. Here we demonstrate the production of high purity (> 99.7%) H<sub>2</sub> from NH<sub>3</sub> using a catalytic membrane reactor (CMR) in which a Ru catalyst is impregnated within a porous yttria-stabilized zirconia (YSZ) tube coated with a thin, 6 µm Pd film by electroless deposition. The intimate proximity of catalyst and membrane eliminates transport resistances that limit performance in the conventional packed bed membrane reactor (PBMR) configuration. The addition of a Cs promoter enabled complete NH<sub>3</sub> conversion at temperatures as low as 400°C, exceeding equilibrium constraints without the need for a sweep gas. A reactor model was developed that captured CMR performance with high fidelity. NH<sub>3</sub> decomposition was observed to follow first order kinetics due to efficient H<sub>2</sub> removal. Relative to a comparable PBMR, the Ru loading in the CMR was reduced an order of magnitude and the H<sub>2</sub> recovery increased 35%, enabling record volumetric productivity rates (> 30 mol m-3 s-1) that validate its promise for efficient, compact H<sub>2</sub> delivery from ammonia.
A General Methodology for the Enantioselective Synthesis of 1‐Substituted Tetrahydroisoquinoline Alkaloids (2010)

Abstract Starting from tricyclic lactam 2 , which is easily accessible by cyclocondensation of δ‐oxoester 1 with ( R )‐phenylglycinol, a three‐step synthetic route to enantiopure 1‐substituted tetrahydroisoquinolines, including 1‐alkyl‐, 1‐aryl‐, and 1‐benzyltetrahydroisoquinoline alkaloids, as well as the tricyclic alkaloid (–)‐crispine A, has been developed. The key step is a stereoselective α‐amidoalkylation reaction using the appropriate Grignard reagent.
Development and Evaluation of a Device for the Haptic Rendering of Rotatory Car Doors (2010)

Virtual prototyping of car doors enhanced with haptic feedback is a promising way to decrease the number of physical prototypes. We clarify, correct, summarize, and extend our previous work on the haptic simulation of car doors. A fundamental issue is the derivation of the performance specification of a task-optimized haptic interface, which is based on the knowledge of the typical user interaction with a car door and a comprehensive model of the dynamics of a rotatory car door. We reason that a direct drive with a high torque output (≥ 100 N·m) and a high control bandwidth has to be used. Consequently, we created a backlash-free very stiff device providing a safe and high-fidelity haptic rendering. Finally, we conducted an extensive user study with 17 participants. An important result is that the haptic simulation can be reliably used to evaluate different door concepts if the difference between them is larger than 5 N·m. Furthermore, the participants did not like a high effort for closing the door, while both a low and a medium effort are appreciated. This is in accordance with the heuristic findings of the automotive industry, which shows the effectiveness of our virtual prototyping approach.
Growth of high-quality SnS epitaxial films by H2S flow pulsed laser deposition (2014)

SnS epitaxial films were grown on MgO (100) substrates by pulsed laser deposition using a H2S gas as an S source. High growth temperature and high H2S gas flow rate caused re-evaporation and etching of the deposited films; therefore, the optimum condition was limited to a narrow region around 400 °C. The measured bandgap 1.08 eV is consistent with the previously reported theoretical calculation. The films with a S/Sn ratio of ∼1.0 showed the largest mobility of ∼37 cm2/(Vs). The hole transport was dominated by domain boundary potential barriers ∼0.05 eV in height.
Living organism imaging with the adaptive scanning optical microscope (ASOM) (2007)

Imaging of small biological specimens and microorganisms that are living and moving is often hampered by a traditional microscope's small field of view at high resolution. This paper discusses a new optical microscope design, called the Adaptive Scanning Optical Microscope (ASOM), which uses a deformable mirror combined with a custom scanner lens to effectively enlarge the field of view. Using a high speed scanning mirror in a post-objective configuration, the ASOM captures a complete image (not a single point) at each scan position and assembles image mosaics on the fly. Consequently, this microscope offers advantages when compared to moving stage based approaches or confocal microscopes. Whereas previous work on imaging motile organisms has primarily focused on tracking only one temporally challenging specimen at a time within a single field of view, this microscope is well suited for tracking multiple moving organisms or monitoring larger organisms at both the full animal and single cell levels simultaneously. In studies requiring manipulation, probing, or sensing, the ability of the microscope to automatically monitor several regions of the specimen without agitating the workspace is particularly advantageous. Using a low cost prototype of the ASOM, we illustrate the basic capabilities of the instrument by imaging multiple living and freely moving <i>Caenorhabditis elegans</i> nematode worms. In addition to transmitted, reflected, and epifluorescent illumination modes, we have also integrated an LED light source that can be rapidly turned on and off in synchronization with the scanning to minimize unnecessary light exposure to the specimens.
