Investigation of the Combustion Products of Ionic Liquid-Based Green Propellants Using Infrared Spectroscopy

Aerospace
In rocketry today, conventional hypergolic propellant combinations typically use hydrazine-derived fuels and oxidizers based on nitrogen tetroxide. Due to their high toxicity and consequently expensive handling, safer alternatives, so-called “green ...

2D Co‐Mo‐Hydroxide‐Based Multifunctional Material for the Development of H2‐Based Clean Energy Technologies

Advanced Materials, EarlyView.
2D α‐Co(OH)2 interleaved with Mo species displays an appealing dual functionality for the production and use of green hydrogen.Mo incorporation greatly benefits the electrochemical behaviour in Oxygen Evolution Reaction for H2 production, while the magnetocaloric response at liquid H2 temperature paves the way for alternative cryogenic refrigerants ...

Polymorph‐Specific Electronic Transduction in WO3 during Molecular Sensing

Advanced Materials, EarlyView.
Metal‐oxide polymorphs with similar surface chemistry can nevertheless exhibit distinct sensing properties. In γ‐ and ε‐WO3, analyte adsorption appears comparable; yet, only ε‐WO3 induces a pronounced lattice electronic perturbation that accommodates charge in sub‐conduction band minimum states.

Determining the quantitative composition of an unknown gaseous fuel and combustion products from the measured process parameters in the fuel combustion process

Trudy Odesskogo Politehničeskogo Universiteta, 2014
There exists a wide range and a considerable potential of alternative (non-certified) gas fuel types. Uncertainty and flexibility of non-conventional fuels’ composition seriously limits the possible exploitation of these energy sources.
