The Electrochemical Society Interface • Fall 2004 ydrogen storage is a crucial step for providing a ready supply of hydrogen fuel to an end use, such as a car, as it is considered by many to be the most technically challenging aspect of achieving a hydrogen-based economy. Current hydrogen storage materials or systems are still far short of meeting target goals set for either 2010 or 2015. Two k...

The phenomenon of CP violation in the B system and strategies for extracting CKM phases are reviewed. We focus both on general aspects and on some recent developments including CP-violating asymmetries in Bd decays, the Bs system in light of a possible width difference ∆Γs, charged B decays, and SU(3) relations among certain transition amplitudes. In order to describe the relevant non-leptonic ...

In this contribution, for the first time, an efficient model of multi-objective product blending fixed-charge transportation problem with truck load constraints through transfer station is formulated. Transfer inserts cost and type-I fixed-charge. Our aim to analyze extra that treats as type-II in designed required when amount items exceeds capacity vehicle fulfilling shipment by more than one ...

transportation is by people and for them. it is a process of providing mobility and accessibility for people both as passengers and as consumers of the goods. therefore it is true when today there is an emphasis on the considering transportation the most influential development in every society. regional development cannot properly be happened without enough transportation infrastructure and qu...

the storage capacity of hydrogen on na-decorated born nitride nanotubes (bnnts) is investigated by using density functional theory within quantum espresso and gaussian 09. the results obtained predict that a single na atom tends to occupy above the central region of the hexagonal rings in (5,0) and (3,3) bnnt structures with a binding energy of -2.67 and -4.28 ev/na-atom respectively. when a si...

ii Τὸ εὖ γίνεσθαι μὲν παρὰ μικρόν, οὐ μὴν μικρὸν εἶναι. Abstract The world's first commercial High Voltage Direct Current (HVDC) transmission link was built in 1954 between the Swedish mainland and the island of Gotland. At that time, it was proved that HVDC transmission is technically feasible. Since then, HVDC cable systems have been used worldwide in electrical energy transportation. Most HV...

zirconium dioxide, commonly known as zirconia, is an interesting material and is receiving growing attention due to its excellent mechanical properties. the solid was characterized for surface area measurements, scanningelectron microscopy (sem), energy dispersive x-ray diffractometry (edx) and potentiometric titrations. surface titrations were carried out at the temperature range 303 to 323k i...
