Sorry, no etymologies found.
Helium hydride is the simplest heteronuclear molecule (besides HD), yet its spectrum had not been observed.
LoGrasso and Wright tackled the main question on everyone’s mind: why lithium-ion when nickel metal hydride is a battery technology that, according to LoGrasso, is “nearing maturity in cost and performance.”
Price is one of them: lithium-ion batteries currently cost twice as much as nickel-metal-hydride, which is why GM says its plug-in Chevy Volt could cost nearly $40,000 when it hits the streets in late 2010.
REINER: No, it is called a hydride -- whatever it is.
Secondly, additional amounts of tritium placed in the proper location nearby the fission device - called a "primary" in this case - begin a fusion reaction There are other ways of doing this, of course The chemicals of choice are lithium-deuteride and lithium-hydride, which is more stable, but tritium is still extremely useful for certain weapons applications '
But Hayasaki said Nissan's unique system enables it to better control the motor by using a lithium-ion battery instead of nickel-metal hydride, which is slower in capturing and discharging energy.
In particular, the team identified that the first step of the FTDS-catalyzed reaction involves the transfer of a proton and two electrons, known as a hydride, from a flavin co-factor molecule to dUMP whereas the first step of the TS-catalyzed reaction involves an amino acid from the enzyme's active site forming a bond with dUMP.
Under the steeply raked hood, the Prius v hosts the now-familiar Prius gas-electric drivetrain, consisting of a 1.8-liter gas engine working with two motor/generators and the nickel-metal hydride battery pack, sluicing mechanical force and regenerated electrons back and forth through the car's power-splitting planetary gearset.
Toyota's Hybrid Synergy Drive, the energy management system first deployed in the Prius, has proven to be dead reliable, and the nickel-metal hydride battery packs have outlasted even the most optimistic estimates.
