In response to the growing trend of greenhouse gas emissions from production and use conventional fuels, COx free hydrogen generation is introduced as an alternative efficient energy carrier. Due hydrogen’s storage challenges, more be produced on-site by other chemical compounds for fuel cell applications. This work outlines (H2) ammonia (NH3) hydrous hydrazine (N2H4·H2O) catalytic decompositio...

We have investigated the adsorption of hydrazine (N2H4) and its reactivity on terraces and steps of Cu(111) surfaces by first-principles calculations in order to gain insight into the hydrazine decomposition mechanism. We have investigated different possibilities for the N-N and N-H bond cleavage for any intermediate states by analysing the reaction and barrier energies of each elementary step....

Chromium selenide (Cr2Se3) nanoparticles were prepared by hydrothermal method from Cr(NO3)3.9H2O and SeCl4 as precursors. These nanoparticles could be produced simply in the presence of cetyltrimethyl ammonium bromide, sodium dodecyl sulfate and polyethylenglycole 600 (PEG600) and 4ml of hydrazine hydrate (N2H4.H2O) at 180 ˚C for different times. By varying the reducing agent to potassium boroh...

We have designed and realised a micromachined micro Coriolis flow sensor for the measurement of hydrazine (N2H4, High Purity Grade) propellant flow in micro chemical propulsion systems. The sensor should be able to measure mass flow up to 6 mg/s for a single thruster or up to 24 mg/s for four thrusters. The sensor will first be used for measurement and characterisation of the micro thruster sys...

The graphene which is a two dimensional carbon structure has been significantly explored due to its excellent mechanical and physical properties. Based on its prominent properties, graphene has a wide range of useful applications. Among the methods for synthesizing graphene, chemical method is known as the most powerful method for mass production of graphene. During the process, to achieve high...

In this article, we established a fluorescent chiral recognition and detection method for cysteine based on the L-glutathione (L-GSH)-stabilized Ag nanoclusters (AgNCs) with high selectivity and sensitivity. A fast and green microwave (MW)-assisted strategy has been employed for synthesizing water-soluble fluorescent L-GSH-AgNCs. The reaction time was shortened from hours to several minutes. Th...
