Properties of phagraphene via hydrogenation and fluorination

We demonstrate that there is an inherent capability for the electronically-elastic RIXS to map the potential energy surface and to perform vibrational analysis of the electronic ground state in multimode systems. We show, that the control and selection of vibrational excitation can be performed by tuning the X-ray frequency across core-excited molecular bands and it is clearly reflected in the RIXS spectra. Using high level ab initio electronic structure and quantum nuclear wave packet calculations together with high resolution RIXS measurements we discuss in great detail the mode coupling, mode localization and anharmonicity in the studied systems.

Fluorination of Graphene with XeF2 A wide band gap semiconductor: Fluorination of Graphene with XeF2 Changes of optical transparency Raman signatures of florographene formation of graphene due to fluorination.

Graphene chemistry is important in large scale fabrication of electronic devices at molecular level. Graphene Chemistry is developing following the chemistry of fullerene and carbon nanotubes. The flat two-dimensional structural nature of graphene is expected to offer opportunities to perform myriad chemical reactions and the true chemical nature of graphene needs further attention.

The zero band gap electronic structure enables it to function as diene or dienophile in the Diels-Alder reaction.

Decarboxylation of the Carboxylic Acids: Alkanes might be prepared by decarboxylation of carboxylic acids via heating a mixture of the sodium salt of a carboxylic acid by soda lime.

Soda lime is a mixture of NaOH and CaO. The active ingredient NaOH, CaO assists in keeping the reaction mixture porous. A nitroalkene, or nitro olefin, is a functional group combining the functionality of its constituent parts, an alkene and nitro group, while displaying its own chemical properties through alkene activation, making the functional group useful in specialty reactions such as the Michael reaction or Diels-Alder additions.
