Steam reforming of methanol can be considered as an attractive reaction aiming at hydrogen production for PEM fuel cells. Although Cu/Al-contained catalysts are considerably evaluated in this reaction, further evaluation is essential to evaluate the impact of some promoters like Pt in order to find a comprehensively optimized catalyst. Pt promoter is employed with different methods in this ...

Magnetizing the fuel in inertial confinement fusion relaxes ignition requirements by reducing thermal conductivity and changing the physics of burn product confinement. Diagnosing the level of fuel magnetization during burn is critical to understanding target performance in magneto-inertial fusion (MIF) implosions. In pure deuterium fusion plasma, 1.01 MeV tritons are emitted during deuterium-d...

Diesel is the main fuel choice for commercial vehicles (Freight Transport Association, 2011a, Hill et al., 2011) and its combustion produces CO2 which is considered the main contributor to global warming (Barreto et al., 2003, Lee et al., 2011). For this reason, the government has targeted road transport to reduce its carbon footprint and it has developed different policy instruments to achieve...

Fire spread through chaparral fuels is a significant feature of wildland fire in southern California. In order to study the detailed physical processes involved during fire spread, FIRETEC, a coupled atmosphere/wildfire behavior model was refined to examine chaparral fire behavior. FIRETEC combines a sophisticated fine-scale model to simulate a threedimensional wildfire, moving over a terrain-f...

Correction for 'All-solid-state Z-scheme system arrays of Fe2V4O13/RGO/CdS for visible light-driving photocatalytic CO2 reduction into renewable hydrocarbon fuel' by Ping Li et al., Chem. Commun., 2015, 51, 800-803.

An experimental investigation on the reduction of nitrogen oxide emission from swirling, turbulent diffusion flames was conducted using a prototype multi-annular burner. The burner utilizes swirl-induced centrifugal body forces to dampen turbulent exchange between the fuel and air streams, allowing an extended residence time for fuel pyrolysis and fuel-N conversion chemistry in a locally fuel-r...

Population growth, industrialisation worldwide and the consequent increase in the use of fossil fuels such as petroleum contribute to the advancement of environmental damage. Burning fossil fuels releases carbon dioxide (CO2) into the atmosphere, which contributes to an increase in the earth's greenhouse effect and climatic change (Balat & Balat, 2010). Factors such as increased demand for ener...

Ultra-portable devices like wireless autonomous sensors can be as ubiquitous as cellular phones, if not more, because, among other things, they can retrofit and convert older macro-scale technologies that are difficult to upgrade and expensive to replace in places like factories, power plants, hospitals, and every-day living spaces into intelligent energyand power-efficient solutions [1]. The p...

Direct numerical simulation (DNS) is used to study chemically reacting, laminar vortex rings. A novel, all–Mach number algorithm developed by Doom, Hou, & Mahesh [1] is used. The chemical mechanism is a nine species, nineteen reaction mechanism for H2/air combustion proposed by Mueller et al. [2]. Diluted H2 at ambient temperature (300 K) is injected into hot air. The simulations study the effe...
