A system level microreactor concept for hydrogen generation with Sodium Borohydride (NaBH4) is demonstrated. The uniqueness of the system is the transport and distribution feature of fuel (hydrogen) to the anode of the fuel cell without any external feed connectors and flow fields. The approach here is to use palladium film instead of feed connectors and the flow fields; palladium’s property to...

Oxygen Reduction Reaction (ORR) is the bottle-neck strategic reaction ruling fuel cell efficiency process. The slow kinetics of require highly effective electrocatalysts for proper boosting. In this field, composite catalysts formed by carbon nanotubes functionalized with palladium(II) complexes showed surprising catalytic activity comparable to those a commercial Pt electrode, but mechanisms t...

The axolotl has extraordinary regeneration capacity compared to other vertebrates. This remarkable potential been attributed its life-long neoteny, characterized by the exhibition of embryonic characteristics at adult stage. A recent study provided a detailed morphological analysis sperm morphology Ambystoma mexicanum using routine and histological techniques. primary purpose present is describ...

Schiff base 2–Hydroxy–5–methoxy Benzaldehyde – Tris [HMBT] Ligand is a new chromogenic reagent have not been used so far for the determination of copper and palladium in trace quantities. Effect of p H on wave height for COPPER[HMBT] PALLADIUM –[HMBT] systems have been studied at p H 7-8.5 and 8.5-11.5 for Copper and Palladium respectively in 0.1 m molar NaNo3 and 0.002 % Triton –x–100 which in...

Poly(o-anisidine) molybdophosphate was expediently obtained by sol-gel mixing of Poly(o-anisidine) into the inorganic matrices of molybdophosphate, which was allowed to react with silver nitrate to the formation of poly(o-anisidine) molybdophosphate embedded silver nano composite. The composite was characterized by Fourier Transform Infrared Spectroscopy, X-ray powder diffraction, UV-Vis Spectr...

In this study, an efficient method for using pulsed plasma to produce hydrogen from ammonia was developed. An original pulsed plasma reactor with a hydrogen separation membrane was developed for efficient hydrogen production, and its hydrogen production performance was investigated. Hydrogen production in the plasma was affected by the applied voltage and flow rate of ammonia gas. The maximum h...

Resistive based hydrogen sensing, for safety applications for example, usually involves the reversible conversion of palladium (Pd) into palladium hydride (PdH0,7). This chemical conversion induces a resistivity change while the sensitive material changes from metal to semi-metal state in presence of hydrogen. H2 sensing relies on the measurement of the resistivity changes in the palladium base...

Polyacrylonitril (PAN)-supported chitosan (CS) nanocomposite membranes were prepared by cross-linking the CS with 3-aminopropyl-triethoxysilane (APTEOS) via sol-gel method. Pervaporative performances of the CS-SiO2/PAN membrane for dehydration of aqueous alcohol solutions were investigated. From SEM cross-sectional images of the membrane, the spongy pores and the finger-like pores we...

A novel work was performed for fabrication and modification of composite nanofiltration (NF) membrane by polymerization reaction between polyethyleneimine (PEI) and triphthaloyldechloride (TPC). the main purpose of this work was water treatment. polysulfone was applied as a main polymer of substrate. The result of reaction between PEI and TPC would be formation of polyamide layer on the membran...
