Abstract: For improving the tribological performance of hard disk drives, nanometer-thick perfluoropolyether (PFPE) lubricant films are generally treated with ultraviolet (UV) irradiation to bond them to the carbon overcoats of the disks. By modeling UV irradiation as an electron emission and attachment process, we investigate the UV bonding of nonfunctional PFPE Z and functional PFPE Zdol to hydrogenated and nitrogenated carbon surfaces with quantum chemical methods. Our calculation results show that, upon electron attachment, Z dissociates at its main chain to two fragments terminated by CF2CF2 and CF2O groups, whereas Zdol dissociates to a hydrogen fluoride and a fragment. The perfluoromethoxy oxygen in one of the Z fragments and the carbon radical and the hydrogen-truncated end group in the Zdol fragment interact strongly with sp2 and oxidized sites on carbon surfaces. Imine moieties on the CNx surface also contribute considerably to the UV bonding of Zdol.

Abstract:
 plays an important role in catalysis, due to its ability to store and release oxygen depending on the condition present in the catalyst environment. To analyze the role of ceria in  it is necessary to know the details of the interaction of  with environmentally sensitive molecules. This study was conducted using ultra accelerated quantum chemical  UA-QCMD to investigate the reduction processes of the (1 1 1) and (1 1 0) surfaces of ceria with  as well as water desorption mechanisms from the surfaces. This simulation demonstrated that when high-energy colliding hydrogen's are adsorbed on the ceria, it pulls up an O atom from the ceria surfaces and results in the formation of a H2O molecule. This is the first time quantum  have been used for such reduction processes.

Abstract: In this article modeling of  of hydrogen on Pd (1 1 1) surface by ultra-accelerated quantum chemical  (UA-QCMD) was reported for the better understanding of the role of hydrogen vacancy for the dissociative adsorption of hydrogen. Here we have demonstrated and examined the isolated steps of hydrogen dissociative adsorption on Pd (1 1 1) surface. The direct observations of dissociative adsorption of hydrogen on Pd (1 1 1) surface (different vacancy models) were successfully simulated. From the analysis of the change of electronic structures and the dynamics of dissociative , we can conclude that divacancy sites are inactive for dissociative adsorption of hydrogen on Pd (1 1 1) surface. Our findings suggest that H2 dissociation on Pd (1 1 1) requires an ensemble of at least three hydrogen vacancies.

This study was conducted using ultra accelerated quantum chemical .
