| Abstract: | We report observation of high weight percentage hydrogen uptake at room temperature in a titanium-ethylene complex formed through vapor deposition in a ultra high vacuum chamber. An uptake upto 14% by weight is observed in monolayer films. Substitution of hydrogen with deuterium confirms the gravimetric percentage via a doubling. Such molecular level gravimetric observations are made possible with a high resolution quartz sensor based technique. The validity of this quartz sensor based gravimetric method is verified through H2 absorption measurements on a standard sample of samarium and through O2 absorption measurements on vanadium nanoparticles. |
