Combustion studies of metallized fuels for solid fuel ramjets
21st Joint Propulsion Conference, 1985Combustion phenomena of highly metallized, boron containing, solid fuels in solid-fuel ramjets (SFRJ) were studied by means of high-speed photography using a windowed two-dimensional SFRJ combustor. The ex- periments indicated the existence of a gas-phase diffusion flame of the volatile fuel ingredients within the bound- ary layer above the fuel ...

Metal, Metal Oxides, and Metal Sulfide Roles in Fuel Cell
2021Today, energy generation is the most challenging issue for scientists and engineers, since their goal to produce energy via economic, efficient, clean, and environmentally friendly processes. Fuel cells have turned chemical energy which is obtained from fuel gas directly into electrical energy that is both efficient and environmentally clean because of

Metallic fuels are neutronically ideal for fast reactors because they produce an extremely hard neutron spectrum. Early metallic fuels had little endurance, due to excessive swelling. By incorporating space for swelling, very high burnups are now routinely achieved.

Hybrid combustion with metallized fuels
29th Joint Propulsion Conference and Exhibit, 1993A chemical method of adding certain catalysts to improve the degradation process of a solid fuel is discussed. Thermogravimetric (TGA) analysis used to study the fundamental degradation behavior of a typical hybrid fuel (HTPB) shows that high surface temperatures increase the degradation rate. Fuels were tested in a laboratory-scale experimental hybrid

Advances in Metallic Nuclear Fuel
JOM, 1987Metallic nuclear fuels have generated renewed interest for advanced liquid metal reactors (LMRs) due to their physical properties, ease of fabrication, irradiation behavior, and simple reprocessing. Irradiation performance for both steady-state and transient operations is excellent.

Metal-Free Motifs for Solar Fuel Applications
Annual Review of Physical Chemistry, 2017Metal-free motifs, such as graphitic carbon nitride, conjugated polymers, and doped nanostructures, are emerging as a new class of Earth-abundant materials for solar fuel devices. Although these metal-free structures show great potential, detailed mechanistic understanding of their performance remains limited.

Laser dispersion and ignition of metal fuel particles
Review of Scientific Instruments, 2011The development of a laser-shock technique for dispersing Al metal fuel particles at velocities approaching those expected in a detonating explosive is discussed. The technique is described in detail by quantifying how air drag affects the temporal variation of the velocity of the dispersed particle plume. The effect of particle size is incorporated by
