Fast electrons produced by a 10 ps, 160 J laser pulse through laser-compressed plastic cylinders are studied experimentally and numerically in the context of fast ignition. K(α)-emission images reveal collimated or scattered electron beam depending on initial density compression timing. A numerical transport model shows that implosion-driven electrical resistivity gradients induce strong magnetic fields able to guide electrons. The good agreement with measured sizes provides first...
We have investigated the effect of pressure on hydrogen bonding in liquid methanol using Raman spectroscopy. Specifically, we measured OH and CO stretching modes assigned bands, agreement with recent IR crossed molecular beam experiments clusters. At about 7 to 8 kbar, note indications that intrinsic nature clusters our samples has changed. Our results provide support for extend conclusions derived from Monte Carlo simulations, explain anomalies observed by previous researchers, new insights...
Inconel 625 (IN625) coatings were deposited by High-Velocity Oxy-fuel (HVOF) and laser cladding, on a 10.50–12%Cr steel to improve its oxidation resistance. Both as-deposited exhibited γ-Ni-Cr matrix two protective oxides (Cr2O3 NiCr2O4). In addition, cladding also presented precipitates A2B-type Laves phases due the dilution effect from technique. Coated uncoated oxidized under isothermal conditions at 600 °C for 2000 h subsequently analyzed using gravimetry, SEM-EDS XRD techniques. The...
Abstract Fast-electron beam stopping mechanisms in media ranging from solid to warm dense matter have been investigated experimentally and numerically. Laser-driven fast electrons transported through Al targets shock-compressed plastic foam targets. Their propagation has diagnosed via rear-side optical self-emission K α X-rays tracer layers. Comparison between measurements simulations shows that the transition collision-dominated resistive field-dominated energy loss occurs for a...
The performance of a concentrated solar power plant is strongly driven by its heat storage capacity and evolving through the development new salt mixtures. Molten nitrates, which have already proved their high potential, can be further improved in terms economic environmental aspects, with mitigation toxic compounds higher electricity generation capability. In this work, stability range energy density characterisations were performed on nitrate ‘Solar’ salt, along life cycle assessment,...
The present study compares the biomass corrosion behavior of two diffusion aluminide coating obtained by slurry application, which were deposited on low-chromium content steels, ferritic-martensitic P92 (8.7 wt% Cr) and ferritic T22 (2 Cr). Their performance degradation was conducted under an oxy-fuel combustion environment for both coated uncoated materials laboratory conditions in a pilot plant burning thistle 500 h. Exposures carried out at different temperatures, 600 °C 650 °C, model...
Abstract new enzyme, usnic acid dehydrogenase, which catalyzes the reduction of ʟ-usnic acid, has been isolated from cell-free extract Evernia prunastri thallus. Purification enzyme (approx. 150-fold with a recovery 42%) can be achieved by using gel adsorption and filtration techniques. The apparent molecular weight is 450000. Cofactor requirement restricted to NADH. Kinetics show an allosteric behaviour for both Structure reaction product described.
Abstract The technique of CVD in a fluidized bed reactor (CVD‐FBR) has useful application obtaining protective coating on substrate using low work temperature, less than 600 °C. In this way, ferritic steels such as P‐91, P‐92, or P‐122 can be coated at temperatures that do not change their microstructural properties. Coatings improve the chemical properties substrates and high temperature durability corrosive environments. aim paper is general review deposition, co‐deposition, modified...
A conventional austenitic AISI 309S stainless steel has been subjected to high temperature oxidation at 950°C under atmospheric pressure of air. Isothermal as well 1 h and 10-h cyclic runs have conducted in order get acquainted with the resistance this establish maintain oxide scales upon such aggressive environments. It will be shown that isothermal oxidation, develops chromia Cr-Mn spinel oxides some internal Si-rich structures which may peg scale alloy. The nature phases not changed...
High resolution, wide field-of-view, infrared (IR) imagers find use in defense and civilian applications. The most demanding of them desire uniform sensitivity across an image's field view, while maintaining a small light-weight optical design. These attributes can be achieved by curving the focal plane array to reduce need for curvature correction. Using experimental numerical methods, we investigated spherical hybridized arrays demonstrate mechanical feasibility opto-electronic...

Satellite communications are now specially developing for land vehicles, since they provide a wide area coverage. The current state of the art makes possible both transmission to and reception from satellites. Although some systems this kind use omnidirectional antennas, space segment system is simplified if directive antennas employed. This paper explains design, building operation new adaptive, electronically steered phased array, which can search keep on tracking one or more satellites by...
