This paper evaluates the potential of hydrogen (H2) and ammonia (NH3) as carbon-free fuels. The combustion characteristics NOx formation in H2 NH3 at different air-fuel equivalence ratios initial concentrations fuel gas were experimentally studied. burning velocity improved because increased amounts atom flame with addition H2. could be moderately applied to commercial engine together has an accelerant role H2–NH3–air combustion, whereas a major effect on maximum H2–NH3–air. In addition,...
Waste plastics offer valuable feedstock for refining facilities. Their well-structured molecular compositions and functional groups make them ideal candidates conversion into high-value chemicals fuels, playing a pivotal role in carbon recycling. Achieving this transformation demands not only the precise design of deconstruction reaction systems but also overcoming technological barriers, necessitating collaborative partnership between fundamental research industrial expertise. In context,...
A 170 GHz gyrotron has been developed at JAEA, which achieved operation of 1 MW/800 s and up to 55% efficiency. This is the first demonstration a achieving even exceeding ITER operating requirements MW/500 50% In addition demonstrated for h with an output power 0.6 MW. The oscillation was stable all cooling water temperatures vacuum pressure reaching equilibrium conditions during pulse length either level. successful aided by very low level stray radiation (∼2% power), contributed fast...
Recent progress on the high power gyrotron development in JAEA is presented. The featured to have a triode-type magnetron injection gun, cylindrical resonator working at 170 GHz with TE 31,8 mode, water-cooled diamond window and depressed collector. After demonstration of ITER basic performance, has been operated for 3 years, recorded ∼200 GJ total output energy. Next, which oscillates higher order 31,12 , designed fabricated study long pulse oscillation greater than 1 MW. In parallel,...
ABSTRACT The structure of solid polymer electrode and catalyst ink fuel cell has been investigated by focusing‐ (FSANS) contrast‐variation small‐angle neutron scattering (CV‐SANS). electrode, consisting carbon (C), platinum, ionomer (polymer, P), exhibited a power‐law function with two asymptotes, i.e., from I ( q ) ∼ −1 to −4 crossover around ≈ 0.005 Å . functions the ink, electrodes dispersed in water, were successfully decomposed corresponding partial factors, S CC ), PP CP exclusively...
Nonactivated and activated biochars have been successfully prepared by bananas at different thermotreatment temperatures. The biochar generated 900°C (Biochar-act900) exhibited improved oxygen reduction reaction (ORR) evolution (OER) performances in alkaline media, terms of the onset potential current density. Rotating disk electron result shows that average 2.65 electrons per molecule was transferred during ORR Biochar-act900. highest power density 528.2 mW/m 2 maximum stable voltage 0.47 V...
Incineration is one of the major methods for processing municipal solid waste (MSW) harmlessly; however, it could lead to low combustion efficiency and secondary pollution problems because high moisture content energy density MSW. Torrefaction has been reported be effective in removing improving properties various materials, such as feedstock wood. The aim this study was investigate whether torrefaction used a practical pretreatment method by reducing chloride Typical combustible components...
An excited-state intramolecular proton transfer (ESIPT) fluorophore, 2,6-bis(benzothiazol-2-yl)phenol, was modified with alkoxy groups at the 4-position to obtain methoxy (OMe), ethoxy (OEt), propoxy (OPr), and butoxy (OBt) derivatives. The derivatives exhibit bright red fluorescence in chloroform, giving same spectra a maximum (λmax) 619 nm. However, crystalline state, λmax values of OMe OEt are bathochromically shifted, producing deeper color, whereas those OPr OBt hypsochromically shifted...
