Abstract:

AbstractAtomic-scale characterization of hydrogen and formation of niobium hydrides, using ultraviolet (wavelength=355 nm) picosecond laser-assisted local-electrode atom-probe tomography, was performed for ultrahigh purity niobium utilizing different laser pulse energies, 10 or 50 pJ/pulse or voltage pulsing. At 50 pJ/pulse, hydrogen atoms migrate onto the 110 and 111 poles as a result of stimulated surface diffusion, whereas they are immobile for <10 pJ/pulse or for voltage pulsing. Accordingly, the highest concentrations of H and NbH were obtained at 50 pJ/pulse. This is attributed to the

Abstract:

Recently, for the generation of extremely short pulses, a method was proposed for coherent control of the polarization of a medium, based on the excitation of atomic polarization oscillations and their subsequent arrest using a pair of ultra short pulses. The so-called stopped pulse of polarization of the medium, which appears in the interval between its excitation and de-excitation, can be a source of an extremely short radiation pulse. In this paper, the indicated possibility of generating an isolated attosecond ultraviolet pulse in a three-level resonant medium, the parameters of which corr

Abstract:

Acid produces a dynamic effect on the cell phenotype of Barrett’s esophagus (BE) ex vivo. An acid pulse induces hyperproliferation, whereas continuous acid exposure promotes differentiation. To examine the mechanism for acid pulse-induced hyperproliferation, we studied the Na+/H+exchanger (NHE), which plays a role in the control of intracellular pH and cell proliferation. NHE was inhibited pharmacologically in endoscopic BE biopsies using amiloride analogs. Cell proliferation was assessed after pulsed or continuous acid exposure using tritiated thymidine incorporation assays and immunohistoche

Abstract:

In this study, an ultrasonic optical fiber hydrogen sensor was newly developed for monitoring and detecting hydrogen leakages. Previously, we developed a pulse-echo sensor system for health monitoring system. Ultrasonic wave, generated from a piezoelectric actuator, is guided and propagated through the optical fiber and subsequently sensed by a piezoelectric sensor in the pulse-echo sensor system. For the detection of hydrogen, the optical fiber was coated with palladium particles, which expanded on exposure to hydrogen. Palladium was used, because it adsorbs hydrogen gas and swell slightly to

The selective excitation of the high ground vibrational state of rotationless HF in an unobserved quasi-resonant thermal environment under the control of a single pulse and pulse train is studied using the reduced density matrix theory. It is shown that the pulse train can enhance the population transfer probability. The numerical results reveal that the vibrational relaxation process is affected by the distribution of the environment frequency and the molecule–environment coupling intensity.

A Pulse Detonation Engine (PDE) is a propulsion device that takes advantage of the pressure rise inherent to the efficient burning of fuel-air mixtures via detonations. Detonation initiation is a critical process that occurs in the cycle of a PDE. A practical method of detonation initiation is Deflagration-to-Detonation Transition (DDT), which describes the transition of a subsonic deflagration, created using low initiation energies, to a supersonic detonation.
