The performance of several palladium precatalysts, namely, palladium(II) acetate, palladium(0) nanoparticles encapsulated into poly(amidoamine) (PAMAM) dendrimers (Pd DENs), and palladium(II)-PAMAM complexes, in the Stille reaction between trichloro(phenyl)stannane and iodoarenes in water is compared. The reactivity of Pd DENs is similar or inferior to that of palladium(II) acetate, although th...

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...

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...

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...
